How to Write Terms and Conditions for a Construction Quote

Most tradespeople don’t have terms and conditions. The ones who do have usually borrowed them from somewhere and haven’t read them properly. Well-written T&Cs protect you in a dispute, set clear expectations with customers, and signal professionalism. They don’t need to be complex – but they do need to cover the right things.

Here’s what your construction quote T&Cs should include and how to present them.

Why Terms and Conditions Matter

A quote without terms is a number on a page. A quote with clear terms is a contract. When a customer accepts your quote (in writing), they’re accepting your terms. If a dispute arises about payment, scope, delays or defects, your terms define the rules of engagement.

Without them, disputes are resolved on the basis of what can be proved – which usually means whoever has the most contemporaneous written evidence wins. With them, the key points are pre-agreed.

What to Include

1. Payment Terms – Deposit amount (e.g. 25% before work commences) – Stage payments if applicable – Balance due on completion / within X days of practical completion – Accepted payment methods – Late payment: state you reserve the right to charge statutory interest on overdue commercial invoices

2. Quote Validity – Quote valid for 30 days (or your preferred period) from date of issue – After this, prices may be subject to revision

3. Scope and Variations – Work covered is as described in the quote only – Any additional work outside the quoted scope will be quoted separately before proceeding – Verbal instructions do not constitute a variation instruction – written confirmation required – Price not inclusive of any work behind walls, under floors or in concealed areas unless specifically stated

4. Access and Site Conditions – Customer to provide clear access to the work area – Removal of furniture/fittings the customer’s responsibility unless quoted – You are not responsible for damage to existing surfaces unless caused by negligence

5. Materials – Materials as specified in the quote; substitutions subject to agreement – Materials remain your property until full payment received – Customer responsible for allowing reasonable materials storage on site

6. Timescales – Start and completion dates are estimates unless specifically agreed as fixed – You are not liable for delays caused by third parties, weather, or factors outside your control – Customer delays (late decisions, failure to provide access) may affect programme and attract additional costs

7. Defects and Guarantee – You will return to remedy defects caused by your workmanship within [your specified period – typically 12 months] – Guarantee does not cover fair wear and tear, customer misuse, or damage caused by others – You are not responsible for pre-existing defects discovered during the work

8. Liability – Your liability is limited to the value of the contract – You are not liable for consequential losses (loss of use, loss of income etc.) – Nothing limits liability for death or personal injury caused by negligence

9. Dispute Resolution – Disputes to be raised in writing within X days of the issue arising – Parties to attempt resolution by negotiation before involving third parties

How to Present Them

You don’t need to attach a 10-page legal document to every quote. A clear, well-written terms section at the bottom of your quote document works perfectly. Alternatively, a separate one-page T&Cs document referenced in the quote (“our standard terms and conditions apply, available at…”).

The key is that the customer has had the opportunity to read them before accepting the quote. If they accept the quote, they’ve accepted the terms.

Getting Them Checked

For a standard residential or small commercial construction business, you can draft terms yourself using the headings above. A one-hour review by a construction-experienced solicitor will cost £100-200 and is worth it for peace of mind.

For larger commercial work, you’ll be operating under JCT or NEC contracts which have their own terms – your T&Cs are less relevant in that context.

Conclusion

The trades industry rewards those who combine excellent work with professional business practices. The guidance above covers the practical fundamentals – applying it consistently is what separates the tradespeople who stay busy and profitable from those who struggle with feast-and-famine cycles.

Frequently Asked Questions

Do I legally need T&Cs for construction work?

No, they’re not legally required. But without them you have no pre-agreed framework for resolving disputes. A quote accepted without T&Cs still forms a contract – the terms are just implied by law and common practice, which is far less certain than explicit written terms.

Can I use T&Cs I found online?

Be careful. Generic business T&Cs often don’t address construction-specific issues (CIS, CDM duties, defects liability, materials ownership). Use them as a starting point but review carefully, ideally with professional input.

What if a customer crosses out or changes my T&Cs?

Technically, this is a counter-offer which you can accept, reject or negotiate. In practice, if a customer significantly changes your terms before signing, have a conversation about it before proceeding.

Do T&Cs need to be in a specific format?

No. Clear, readable plain English is better than dense legal language. Courts consistently find that T&Cs written in accessible language are more enforceable than ones that appear designed to confuse.
