Tradesman Contract UK 2026: 10 Legal Requirements, Consumer Rights Act Obligations, 1 in 5 Tradespeople Face Non-Payment Dispute
A free, practical contract template covering scope of work, payment terms, variation clauses, dispute resolution, and your obligations under the Consumer Rights Act 2015.
Why Every Job Needs a Written Contract
Most tradesmen start out trusting a handshake. It works — until it doesn't. The reality is that 1 in 5 tradesmen experience a non-payment dispute each year, and the single biggest factor in how that dispute ends is whether a written contract exists.
Without a contract, a customer can dispute the agreed price, claim the scope was different, or simply refuse to pay and dare you to take them to court. With a contract, you have a signed record of exactly what was agreed — and courts will enforce it.
Under the Consumer Rights Act 2015, if you're working for a consumer (not a business), you already have legal obligations whether you write them down or not. A written contract makes those obligations explicit and protects both parties. It also demonstrates professionalism and reduces the number of disputes that arise in the first place — customers who understand exactly what they're getting tend not to dispute it.
A written contract also protects you from County Court Judgements (CCJs). If a customer takes you to the small claims court claiming poor workmanship or a billing dispute, a clear contract is your primary defence. Without one, the judge has very little to go on except witness statements — and you may lose a case that was entirely in your favour.
Key stat
1 in 5 UK tradesmen experience a non-payment dispute each year. Tradesmen with written contracts recover unpaid invoices at a significantly higher rate than those relying on verbal agreements alone.
Legal Requirements Under the Consumer Rights Act 2015
The Consumer Rights Act 2015 (CRA) applies any time you contract with a consumer — that is, an individual acting outside their trade or business. Most domestic work falls under this Act.
Under the CRA, all services provided to consumers must:
- 1Be performed with reasonable care and skill — the standard expected of a competent tradesman in your trade.
- 2Be completed within a reasonable time — if no time is agreed, the law implies a reasonable timeframe based on the nature of the work.
- 3Be provided at a reasonable price — if no price is agreed, the customer only has to pay a reasonable price, not whatever you later decide to charge.
You are also required to provide pre-contract information to consumers, including your full business name, address, and contact details, a clear description of the service, the total price or how it will be calculated, and — for off-premises contracts (work arranged away from your place of business) — the customer's right to cancel within 14 days.
Failing to provide this information does not invalidate the contract, but it can expose you to claims and regulatory action. A well-drafted written contract covers all of this automatically.
Business-to-business contracts
If your customer is a business (e.g. a landlord operating commercially, a developer, or a facilities management company), the CRA does not apply. Instead, your contract is governed by general contract law and the Supply of Goods and Services Act 1982. The key differences: no mandatory cancellation rights, and the implied terms about care and skill still apply but the remedies differ.
The 10 Things Every Contract Must Include
A contract does not need to be long or use legal language. It does need to be clear, complete, and signed by both parties. These are the ten elements every UK tradesman contract should include:
Your full business name, address, and contact details
Include your trading name, registered address, phone number, and email. If you are a limited company, include your Companies House registration number. If VAT registered, include your VAT number.
Customer name and address
The full legal name of the customer and their billing address. For business customers, include their company name and registered address.
Job site address (if different)
Where the work will actually be carried out. This matters for insurance purposes and is important evidence if a dispute about site access or condition arises.
Detailed scope of work — what IS included
Be specific. Not 'bathroom renovation' but 'supply and fit new toilet, basin, and bath; tile floor and walls to 1.2m; fit new chrome towel rail; connect to existing waste and supply pipes'. The more detailed, the better protected you are.
What is NOT included (exclusions)
Explicitly state what you are not doing. Common examples: making good of surfaces after trades, disposal of waste beyond X bags, structural work, specialist electrical or gas work, or dealing with hidden defects discovered during the job.
Start date and estimated completion
Include both a planned start date and a realistic completion estimate. Use 'estimated' rather than 'guaranteed' unless you are certain, as delays outside your control (materials, weather, third-party trades) can make fixed end dates risky.
Price and payment terms
State the total price (or how it will be calculated for time-and-materials work), the deposit amount and when it is due, any stage payment schedule, and when the final balance is due. Be explicit: 'Final balance due within 7 days of completion'.
What happens if additional work is found (variation clause)
Any work not in the original scope must be agreed in writing before you proceed. Include a clause requiring written sign-off for all variations, the agreed price or day rate for additional work, and confirmation that no variation will be started without the customer's written authorisation.
How disputes will be resolved
Specify that disputes will first be addressed through written notice, then mediation (through your trade association or a RICS-accredited service), and finally through the county court small claims track if unresolved. This clause demonstrates good faith and often discourages frivolous disputes.
Cancellation rights (for consumer contracts)
For work arranged away from your place of business (which is almost all domestic work), consumers have a 14-day right to cancel under the Consumer Contracts Regulations 2013. You must inform them of this right. If they want work to start within 14 days, they must sign a written request to waive the cooling-off period — otherwise you cannot charge for work done during those 14 days.

Payment Terms — What's Enforceable?
Payment terms need to be agreed upfront and written into the contract. Once agreed, they are legally enforceable — but only if you have them documented.
Business clients
The Late Payment of Commercial Debts (Interest) Act 1998 sets a maximum payment period of 30 days for most B2B contracts (60 days by agreement). After this, you are automatically entitled to charge statutory interest at 8% above the Bank of England base rate, plus a fixed compensation fee of £40–£100 depending on the debt size.
Consumer clients
No statutory limit applies, but you must agree and document terms in advance. Courts will enforce whatever is written in a signed contract. If no terms are agreed, a 'reasonable time' applies — typically 14–30 days after invoice.
Deposits
A deposit of 10–25% of the contract value is standard and reasonable for most jobs. Never request more than 50% upfront, as this is considered unusual by courts and consumer protection bodies and may be harder to justify if a dispute arises.
Staged payments for large jobs
For contracts over £2,000, consider staged payments tied to milestones rather than a single lump sum. This protects you from carrying the cost of materials and labour for weeks before payment, and gives the customer confidence they are only paying for work completed.
Recommended payment structure for jobs over £2,000
- 20% deposit on signing the contract
- 40% at an agreed midpoint milestone (e.g. first fix complete)
- 35% on practical completion
- 5% retention released after agreed snagging period (e.g. 14 days)
Variation / Change Order Clause
One of the most common causes of disputes is "scope creep" — work that was never in the original contract but the customer claims was implied or verbally agreed. A robust variation clause protects you completely.
The golden rule: no variation proceeds without written sign-off, period. Not even if the customer says "just do it, we'll sort the money later." Especially not then.
Template Variation Clause
VARIATION CLAUSE
Any instruction to carry out work outside the agreed scope ("Variation") must be agreed in writing before work commences. The Contractor will issue a Variation Notice stating:
- (a) Description of the additional or amended work;
- (b) The additional cost (or revised total);
- (c) Any adjustment to the estimated completion date.
No Variation will be incorporated into this contract until the Customer has provided written approval (email confirmation is acceptable). Work carried out pursuant to an unconfirmed verbal instruction is carried out entirely at the Contractor's risk and may not be recoverable. The Contractor reserves the right to stop work if a Variation is required and written approval is not provided within [48 hours / a reasonable time].
Send variation notices by email so you have a timestamped record. A simple email saying "As discussed, here is a variation notice for X additional work at a cost of £Y — please confirm by reply" is legally sufficient and takes 60 seconds to send.
What to Do When a Customer Disputes
Even with a perfect contract, disputes happen. The key is responding correctly — a well-handled dispute rarely ends up in court.
Issue a formal written notice
As soon as a customer signals they are disputing a payment or the quality of work, send a written notice by email (and optionally recorded post). State clearly: what is owed, what the contract says, and that you expect resolution within 14 days. Keep the tone professional. This creates a documented paper trail and often resolves disputes without further action.
Attempt mediation
If the written notice does not resolve the dispute, offer mediation. Many trade associations (FMB, NICEIC, Gas Safe, APHC) offer dispute resolution services for members. RICS and CIOB also provide accredited mediators. Mediation is cheaper, faster, and less stressful than court. It also shows good faith — courts take a dim view of parties who refuse reasonable mediation.
Small Claims Court — free up to £10,000
If mediation fails, the county court small claims track handles claims up to £10,000 (£5,000 in Scotland) and is designed to be accessible without a solicitor. Filing fees start from £35 for small claims. You can claim the unpaid debt, statutory interest, and court costs. In a well-documented case with a signed contract, non-payment disputes are very commonly found in the tradesman's favour.
Evidence to gather for any dispute
- Signed contract and any variation notices
- All email and WhatsApp correspondence
- Dated photographs of work at each stage
- Receipts for materials supplied
- Time logs and job notes
- Any customer sign-offs or approvals given
