Most roofing companies grow by winning one domestic customer at a time. It works, but it is fragile — the work is unpredictable, margins vary wildly, and you are always competing against whoever is cheapest on Checkatrade that week. Commercial tenders and framework contracts are a different model entirely.
A single housing association roofing framework can guarantee two or three years of planned maintenance work across hundreds of properties in your area. A local authority re-roofing contract can represent more revenue than twelve months of domestic jobs. These contracts are not reserved for the large national contractors — in fact, UK procurement law specifically requires public bodies to consider smaller local contractors, and many frameworks have lots sized precisely for regional SMEs.
The barrier is not company size. It is knowing how the system works, having the right documents ready, and writing bids that score well rather than bids that merely answer the questions. This guide covers all of it — from understanding the different types of contract available to actually writing a winning tender response.
The four main types of commercial roofing contract
Before you can bid effectively, you need to understand what you are bidding for. Commercial and public sector roofing contracts fall into four broad categories, each with different buyers, processes, and requirements.
Local Authority and Public Sector Contracts
Councils, NHS trusts, schools, emergency services, and central government agencies
Public sector buyers are required to follow the Public Contracts Regulations 2015 (PCR 2015) and, for contracts above the threshold, advertise on Find a Tender Service (FTS). Below the threshold (£213,477 for most works contracts), they can use Contracts Finder or their own portals but still follow transparency requirements.
Public sector buyers are the most process-heavy — they must evaluate against published criteria, keep records of all scoring, and offer debriefs. This transparency works in your favour: you know exactly how bids are scored, you can request feedback after every submission, and you can improve methodically over time. A well-structured response to a public sector ITT has a predictable relationship between input quality and outcome.
Housing Association (Registered Provider) Frameworks
The largest single source of repeat roofing work for regional contractors
Housing associations (Registered Providers of social housing) manage millions of properties across the UK and are required under the Decent Homes Standard and building safety legislation to maintain roofs to a defined condition. They typically run roofing frameworks every 2–4 years, covering both planned maintenance (re-roofing programmes) and responsive repairs.
Housing association contracts are often the most accessible entry point for regional roofing contractors. Many split their frameworks into geographic lots specifically to enable local contractors to compete against national players. The weighting given to social value (local employment, apprenticeships, community investment) in housing association tenders is among the highest in the sector — an area where a local contractor can score well against a large national competitor.
Facilities Management (FM) Subcontracts
Working under a main FM contractor who holds the public sector relationship
Large facilities management companies — Mitie, ISS, Amey, Integral, and others — hold national and regional contracts with councils, NHS trusts, and other public bodies. They are required to deliver specialist roofing work but rarely employ roofers directly. They subcontract to regional specialists and are actively looking for reliable local contractors to add to their approved supply chains.
The advantage of the FM route is that you are not competing against national contractors for the work — you are being asked to supply services to them. The procurement process is lighter than a full public sector tender; many FM companies onboard subcontractors via a supply chain portal or qualification questionnaire rather than a full ITT. The downside is margin compression — FM companies apply a management fee, so rates tend to be lower than direct public sector work.
Private Sector Commercial Frameworks
Retailers, developers, industrial estates, and large commercial landlords
Large commercial landlords, property developers, retailers, and industrial estate managers also run approved contractor frameworks for roofing maintenance, though their procurement is less formally regulated than public sector. These buyers typically issue ITTs via their surveying or estates teams, with decisions driven more by track record, references, and price than by the weighted scoring matrices of public procurement.
The process is faster and less bureaucratic than public sector, but the relationships are harder to access — you usually need a warm introduction via a surveyor, architect, or facilities manager. Building a presence with local surveyors and commercial property consultants (CBRE, JLL, Savills at the large end; independent regional surveyors at the accessible end) is the most reliable path into this segment.
Where to find roofing tenders: the complete UK list
Every public body spending public money is required to advertise contracts openly. The days of council work going to contractors the procurement officer happened to know are largely over for anything above a few thousand pounds. Here is where the work is published:
| Portal / source | Type of contracts | Cost | Notes |
|---|---|---|---|
| Find a Tender Service (FTS) | Public contracts above PCR threshold (£213k+ for works) | Free | Mandatory for all qualifying UK public contracts. Set up email alerts for "roofing" and your region. |
| Contracts Finder | Central government + any buyer choosing to advertise. Lower-value contracts. | Free | Useful for sub-threshold contracts. Also shows awarded contracts — intelligence on who wins what. |
| Local council procurement portals | Council-specific tenders — often use their own portals (ProContract, Proactis, etc.) | Free to register | Register with every council in your operating area. Alerts are essential — portal UIs are poor. |
| Housing association portals | RP-specific tenders. Many large HAs use In-Tend, Delta eSourcing, or their own portals. | Free to register | Identify your local HAs and register on each. The NHF supplier directory lists most RPs. |
| Tracker Intelligence | Aggregates all of the above plus private sector. Alert tools and pipeline analytics. | £1,500–£4,000/yr | Worth the cost once you are bidding regularly. Saves significant daily monitoring time. |
| BiP Solutions / Delta eSourcing | Public and housing sector. Also host many buyer portals directly. | Free basic / paid advanced | Delta is used as the buyer portal by many councils and HAs — register on Delta regardless. |
| Supply chain portals (FM companies) | FM subcontracts — Mitie, ISS, Amey, Integral all have supplier registration portals. | Free to register | Register proactively — do not wait for a specific job to be advertised. Most operate approved lists. |
| LinkedIn and direct outreach | Private sector and commercial frameworks — not formally advertised | Free | Surveyors, estates managers, and commercial property contacts who commission roofing work directly. |
Register on Find a Tender Service with alerts for "roofing," "roof," and "planned maintenance" in your region. Do the same on Contracts Finder. Then identify the 8–12 housing associations operating in your area and register on each of their procurement portals. This setup takes a day and means relevant opportunities land in your inbox rather than requiring daily searches.
Getting tender-ready: the documents and accreditations you need
The single most common reason capable roofing contractors fail to qualify for or win tenders is not the quality of their work — it is the absence of required documents at the time of bidding. Public sector and housing association buyers run pre-qualification checks that are non-negotiable. If you cannot evidence them, you cannot proceed.
How the tender process works: PQQ to contract award
Public procurement follows a structured sequence. Understanding each stage tells you what is being assessed at each point and where your effort is best spent.
Some buyers publish a PIN before formal procurement begins. This signals that a contract is coming and invites market expressions of interest or supplier engagement. PINs are worth responding to — they give you early intelligence on the scope, timeline, and likely requirements, and occasionally buyers use them to shape the final specification. Responding to a PIN does not commit you to bidding, but it puts you in the buyer's awareness before the formal process starts.
Not all tenders include a PQQ stage — some go straight to an open ITT. Where a PQQ exists, its purpose is to shortlist capable bidders before the full tender documents are issued. At PQQ stage you are typically asked to evidence:
- Company details, legal status, and financial standing
- Insurance certificates
- Health and safety accreditation and policy
- Previous relevant contracts (comparable in scale and scope)
- Key personnel qualifications and experience
- References from named clients
The PQQ is essentially a compliance and capability check. Scoring well is less about writing quality and more about having the right documents and presenting them clearly. Most PQQ failures are caused by incomplete responses, expired certificates, or references from clients who cannot be contacted — all preventable with preparation.
The ITT is the substantive stage where the work is won or lost. Shortlisted bidders (typically 3–6) receive the full tender documents: specification, drawings, schedule of rates, and quality questionnaire. Responses are evaluated against published criteria, usually split between quality (method statements, case studies, social value, mobilisation plan) and price (schedule of rates, lump sum where applicable).
After submissions close, the buyer evaluates responses against the published criteria. They may issue clarification questions — points where your response was ambiguous or required expansion. Always respond to clarification requests promptly and thoroughly; a slow or incomplete clarification response has cost contractors contracts that they otherwise would have won.
Notification of award is followed by a 10-day standstill period (the Alcatel period) before contract signature, during which unsuccessful bidders can challenge the decision. Always request a debrief — win or lose. The scoring breakdown you receive in a debrief is the most precise feedback on how to improve your next bid.
How to write a roofing tender that actually scores well
Most roofing contractors who lose tenders do not lose on price. They lose because their quality responses are vague, generic, and fail to provide the evidence evaluators are looking for. Here is how to write ITT responses that score in the top tier.
Answer the question being asked — not the one you want to answer
Every quality question in an ITT has a specific ask. Evaluators mark against that ask — not against the overall impression of your company. If the question is "describe your approach to managing health and safety on site," a response that pivots to talking about your accreditations and years of experience without specifically describing your on-site H&S approach will score poorly, regardless of how impressive the wider content is.
Read each question three times before writing. Identify every sub-component — most questions have two or three distinct parts. Structure your answer to address each part in sequence. Use the question's own language where appropriate; evaluators are often marking against a scoring guide that uses the same words.
The five quality sections that appear in almost every roofing ITT
Method Statement / Technical Approach
Describe precisely how you will deliver the contract — how jobs are instructed, surveyed, scoped, priced, and delivered. Include your quality control process, supervision ratio, and how you handle defects. Generic responses ("we will carry out all works to a high standard") score poorly. Specific process descriptions with named steps score well.
Health & Safety
Describe your site-specific risk assessment process, how you brief operatives before each job, your approach to working at height, and how near-misses and incidents are reported and reviewed. Reference your accreditation but do not rely on it — evaluators want to see your actual practice, not just a certificate number.
Social Value
This is where local contractors can consistently beat national ones. Describe your local supply chain (how much of your spend stays in the region), any apprenticeships or training commitments, community engagement, employment of local people, and environmental commitments. Be specific and quantified: "we commit to employing X% of operatives from within Y postcodes" scores far better than "we support local communities."
Mobilisation and Service Management
How will you be ready to start work on contract commencement? Name your contract manager, describe your response time commitments, your job management and reporting system, how you communicate with the client and with residents/tenants during works, and how you will handle surge demand after storm events.
Case Studies and References
Choose case studies that most closely match the scope and scale of the contract being bid. Include: the client name (with permission), the contract value, the types of work delivered, specific challenges encountered and how they were overcome, and the outcome. A case study with a named referee who can be called scores significantly higher than one with vague or anonymised detail.
Continuous Improvement and KPIs
Some ITTs ask how you will drive continuous improvement across the contract and how you will report performance. Describe the KPIs you will report against (response time, first-time fix rate, customer satisfaction score, defect rate), and how you will share performance data with the client at contract review meetings.
- Use numbered headings to address each sub-question
- Be specific — name people, processes, systems, tools
- Quantify everything possible (response times, satisfaction scores, defect rates)
- Use the buyer's own language from the specification
- Keep sentences short — evaluators are reading many submissions
- Leave time to proofread — typos in ITT responses damage credibility
- Stay within word limits — exceeding them can result in text being cut
- Generic responses copied from a previous bid without tailoring
- Pivoting to what you want to say instead of answering the question
- Opening with company history paragraphs before addressing the question
- Vague commitments ("we will endeavour to…") with no specific content
- Not reading the scoring criteria before writing
- Submitting at the last minute with no time to review
- Failing to provide evidence for claims ("we have excellent H&S" with nothing to back it up)
Pricing commercial tenders: schedule of rates vs lump sum
Commercial roofing tenders are usually priced against a Schedule of Rates (SoR) — a pre-agreed list of unit prices for labour, materials, and plant that the buyer will use to value individual call-off jobs across the contract term. Getting your SoR right is more important than winning on headline rate, because the prices you submit become the basis for every job you carry out over the contract period.
Schedule of Rates: what to watch for
Understand what the SoR actually covers. Review every line item carefully. Some items that appear straightforward (e.g. "replace ridge tile") may include scaffold access in some SoRs and exclude it in others. Items that are priced too low because you misread the scope will erode your margin on every job that includes them for the duration of the contract.
Look at the frequency weightings. Some buyers provide estimated quantities alongside each SoR item to help you understand which items will be called off most often. Price high-frequency, low-complexity items competitively; price rarely-called specialist items at full margin — they have low impact on the overall price score but protect you when those jobs arise.
Factor in mobilisation and contract management overhead. A commercial contract has costs that domestic work does not — contract management time, reporting, resident liaison, compliance paperwork, KPI meetings. These need to be absorbed across your SoR rates; they do not appear as separate line items and will not be added later.
Never price to win at the expense of viability. Buying a contract at unsustainable rates to get on the framework is a common mistake. Buyers will hold you to the submitted rates for the full term. If you cannot deliver at the prices you bid, you will either lose money or start cutting corners — both of which end the relationship.
After you win: mobilisation and performance management
Winning a tender is the beginning, not the end. Commercial contracts have mobilisation requirements — things that must be in place before the first job is instructed — and ongoing performance obligations that are monitored throughout the contract term.
- 📋Appoint a named contract manager — your main point of contact with the client. This person attends contract review meetings, manages performance reporting, and handles escalations. On smaller contracts this may be you; on larger ones it needs to be a dedicated role or at minimum a clearly defined responsibility.
- 📋Set up your job management system — most commercial clients require jobs to be instructed, tracked, and closed on their systems (or yours, linked to theirs). Understand what platform they use and ensure you are set up before day one. Common platforms include Concept Evolution, Maximo, Planon, and bespoke housing management systems.
- 📋Brief all operatives on the contract requirements — every operative working under the contract needs to understand the response time commitments, the resident communication standards (no cold calling, always carry ID, leave the property as found), the reporting requirements, and who their site supervisor is.
- 📋Set up your KPI reporting — agree the KPI framework with the client at mobilisation and build your reporting into your job management system from the start. Trying to reconstruct performance data retrospectively at contract review is time-consuming and error-prone.
- 📋Attend the mobilisation meeting — most contracts begin with a formal meeting with the client's contract manager, the procurement team, and sometimes residents' representatives. Come prepared: bring your mobilisation programme, your emergency contact details, your operative IDs, and your insurance certificates. This meeting sets the tone for the entire contract period.
- 📋Keep records of everything — site visit records, photo evidence for every job, signed job sheets, tenant feedback. Commercial clients run audits. A contractor who cannot produce records for a random sample of completed jobs is in breach of contract regardless of the quality of the underlying work.
The SME route in: how to win your first public sector contract
The first public sector or housing association contract is always the hardest to win because you have no public sector case studies to submit. Here is the most practical path to breaking through.
-
1Start with the FM subcontract route
Register on Mitie, ISS, Amey, and Integral's supply chain portals. FM subcontracting does not require Constructionline Gold in most cases and does not involve a full ITT. Once you have 12 months of verified delivery for an FM client, you have a case study and a reference — both of which are essential for your first direct public sector bid.
-
2Target below-threshold contracts first
Public contracts below £213,477 (for works) are not required to follow the full PCR 2015 process. Many councils and housing associations let small roofing contracts — individual school re-roofs, void property programmes, small estate maintenance — through simplified quotation processes on their procurement portals. These are genuinely accessible to smaller contractors without full Constructionline Gold or extensive public sector case studies.
✅ How to find theseRegister on every local council procurement portal in your area. Filter for roofing-related quotes and low-value works contracts. The competition is lighter, the documentation requirements are lower, and a successfully delivered below-threshold job becomes the case study that gets you into the next tier.
-
3Attend pre-market engagement events
When public bodies are planning large procurement exercises — a new housing maintenance framework, a school roofing programme — they often run a market engagement event where contractors can meet the procurement team, ask questions, and signal their interest. These events are advertised on Find a Tender and Contracts Finder. Attending signals seriousness and gives you direct insight into what the buyer is prioritising before the documents are issued.
-
4Consortium bid with a compatible contractor
If the contract value or geographic scope is beyond your current capacity, bidding as a consortium with another regional contractor can bridge the gap. Procurement regulations permit consortium bidding. The lead contractor takes primary responsibility; the consortium partner contributes capacity, coverage, or specialist skills. It is a legitimate path to contracts that would otherwise be out of reach — provided the partnership is formalised with a consortium agreement before submission.
-
5Request a debrief after every submission — including losses
A debrief from a public sector buyer is not optional on their part — they are required to provide it under PCR 2015. The scoring breakdown you receive tells you exactly where you ranked on each criterion and what the winning bidder scored. Over two or three tender cycles, the pattern of where you are losing points becomes clear and your bids improve methodically. Most contractors never ask for debriefs; the ones who do consistently improve their win rates.
Want commercial clients to find you on Google before you even approach them?
Many procurement officers and housing association surveyors search Google for local contractors before publishing a formal tender — particularly for below-threshold work. Being visible when they search matters. A free visibility audit shows you exactly where you stand in your area.
Get Your Free Visibility Audit →Building a tender library: the asset that compounds over time
Every tender response you write is an investment that should be reused, refined, and improved. Roofers who win consistently in the commercial market do not write every bid from scratch — they maintain a library of pre-written, high-scoring responses to common ITT questions that can be tailored to each specific contract in hours rather than days.
What to include in your library
Master versions of your method statement, H&S approach, equality policy, social value commitments, mobilisation plan, and continuous improvement approach. Three to five case studies in a standard format (client, value, scope, challenge, outcome). All supporting documents in a single, organised folder with clear version dates and expiry tracking.
How to update it after each bid
After every debrief, identify the questions where you scored below the winner. Rewrite those sections using the debrief feedback and save as a new version. After every contract delivery, write a case study capturing the measurable outcomes. The library improves with every cycle — after six or eight bids, your standard responses are materially better than they were at the start.
When to use a bid writer
Professional bid writers typically charge £800–£3,000 per bid depending on complexity. For a contract worth £500k+ over three years, this is a rational investment. For lower-value tenders or your first few submissions, writing yourself and asking a trusted contact to read it as if they were the evaluator is more instructive — the learning you get from writing badly and debriefing is more valuable than outsourced writing you do not understand.
Pipeline management
Track every tender you are aware of — published, imminent, and anticipated — in a simple pipeline spreadsheet. Log the tender reference, buyer, estimated value, submission deadline, and your decision to bid or no-bid. A no-bid decision (where the scope or price weighting makes winning unlikely) is as valuable as a bid decision — it preserves your bandwidth for opportunities you can actually win.
Want a steady pipeline of roofing work beyond domestic one-offs?

Frequently Asked Questions
Where do I find roofing tenders in the UK?
The main free sources are Find a Tender Service (FTS) for public contracts above the procurement threshold, Contracts Finder for lower-value central government contracts, local council procurement portals, and housing association portals such as Delta eSourcing and In-Tend. For FM subcontracts, register directly on the supply chain portals of Mitie, ISS, Amey, Integral, and similar FM companies. Paid aggregator services such as Tracker Intelligence and BiP Solutions pull from multiple portals and are worth considering once you are bidding regularly.
What is the difference between a tender and a framework contract?
A tender is a competitive bid process for a specific defined project — one school re-roof, one housing block maintenance contract. A framework contract is an approved supplier list that a buyer creates by running a single procurement exercise. Once you are on the framework, you can be called off for individual projects without a full tender each time, often for 2–4 years. Frameworks are more valuable long-term as they provide ongoing access to work without repeated full procurement exercises.
What accreditations do I need to win roofing tenders?
The most commonly required accreditations for UK roofing tenders are Constructionline Gold (or an equivalent SSIP scheme such as CHAS or SafeContractor), public liability insurance of at least £5m, employer's liability insurance of at least £10m, and a documented health and safety policy. NFRC membership is not always required but is frequently cited as a quality signal. Some larger contracts also specify ISO 9001 and ISO 14001 certification, though these are less common at SME level.
How long does a typical roofing tender process take?
A typical public sector tender process runs between 8 and 16 weeks from notice to contract award. A PQQ stage, where it exists, takes 3–4 weeks; the ITT stage 4–6 weeks; evaluation and award a further 2–4 weeks. Framework tender processes can take 4–6 months from publication to award. Allow additional time for contract mobilisation before work actually starts — most frameworks have a 4–8 week mobilisation period after award.
Can a small roofing company win public sector contracts?
Yes. The Public Contracts Regulations 2015 require public bodies to consider SMEs and to break contracts into lots where possible specifically to enable smaller contractors to bid. Many housing association and council roofing frameworks include SME lots or reserve certain contract values for regional businesses. The most accessible entry point for smaller contractors is below-threshold quotation processes and FM subcontracting, both of which have lighter requirements than full ITT procurement.
What is Constructionline and do I need it for roofing tenders?
Constructionline is a UK procurement and compliance service that pre-qualifies contractors against a standard set of criteria — insurance, health and safety, financial standing, equalities — so buyers do not have to run the same checks on every tender. Constructionline Gold is specified by the majority of public sector and housing association buyers as a minimum requirement. Annual membership costs approximately £750–£1,500 depending on company turnover. It is not legally mandatory, but in practice it is essential for this market segment.
