As of 13 August 2026, AI can only partly review your UK building contract.

What to actually do

1. Hand it to a person

   The route this page recommends

   Someone with a licence or accountable authority has to sign this before it counts.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 1 hour until you can act on the result.

   How to actually do it

   1. Open the full contract, quotation, plans, specification and payment schedule, and save the versions you were actually sent by the contractor.
   2. Gather written messages that change or clarify the price, materials, start date, completion date, variations, guarantees, access arrangements or responsibility for damage.
   3. Paste the prompt into an AI tool and attach or paste the documents, replacing each bracketed slot with the relevant material and removing documents you do not have.
   4. Ask the AI to identify conflicts by comparing the contract against the quotation, plans, specification and messages, and to quote the exact clause or page for each finding.
   5. Compare every listed price, payment date, scope item, completion obligation and proposed amendment against your source documents and mark any AI finding that does not match.
   6. Send the contract, the AI's issue list and your questions to the contractor for written clarification, then ask a UK solicitor to review the unresolved or high-risk terms before you sign.

   Prompt

   Review the attached contract for building work at a UK home. This is not professional advice. Do not tell me that a clause is legally enforceable or unenforceable unless the wording and context clearly support that conclusion. Do not invent facts, terms, prices, rights or deadlines.
   
   Use the attached contract and the supporting documents below:
   - Contract: [attach or paste the full contract]
   - Quotation or estimate: [attach or paste]
   - Plans and specification: [attach or paste]
   - Payment schedule: [attach or paste]
   - Any written promises or messages from the contractor: [attach or paste]
   - My known facts and concerns: [describe briefly]
   
   Review the documents under UK law at a practical, issue-spotting level. Produce:
   1. A plain-English summary of what each party must do.
   2. A table of every payment, deposit, retention, variation, delay, completion, defect, insurance, termination, cancellation, dispute-resolution and warranty term, with the exact clause reference.
   3. Any conflicts between the contract, quotation, plans, specification and messages.
   4. Terms that are missing, unclear, one-sided or risky for me, explaining the practical consequence without overstating the law.
   5. Questions I should put to the contractor before signing.
   6. Specific drafting changes that would make each unclear or risky point clearer, labelled as suggested wording rather than legal advice.
   7. A final list of issues that need review by a UK solicitor before I sign.
   
   Quote the relevant wording for each important finding. Separate facts from inferences. Flag anything you cannot determine from the documents. Do not approve the contract, do not tell me to sign it, and do not treat a builder's trade association membership, insurance statement or consumer protection claim as verified unless the document proves it.
