As of 13 August 2026, AI can only partly draft a subcontractor agreement.

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 a document and gather the legal names, addresses, company numbers or sole trader details for both the principal contractor and subcontractor.
   2. Collect the scope of work, deliverables, acceptance criteria, site details, programme, milestones, price, VAT treatment and payment arrangements from your quotation or project records.
   3. Ask the subcontractor and project lead to confirm responsibility for materials, equipment, access, permits, health and safety, insurance, variations, defects and delay.
   4. Paste the completed details into the prompt and ask the chatbot to produce the agreement, schedule and separate solicitor review list.
   5. Compare every party detail, date, price, milestone, payment term and responsibility in the draft against the quotation, purchase order and current project instructions.
   6. Send the draft and review list to a UK solicitor, specifically asking them to check liability, indemnities, employment-status risks, insurance, intellectual property, data protection, termination and dispute provisions.
   7. Apply the solicitor's amendments, obtain written agreement from both parties to the commercial terms, then have authorised representatives sign and retain the final version with its schedules.

   Prompt

   Draft a UK subcontractor agreement for the following arrangement. This is a drafting aid, not professional advice, and you must not invent facts or legal requirements.
   
   Principal contractor: [legal name, company number and registered address]
   Subcontractor: [legal name, company number or sole trader details and address]
   Services and deliverables: [describe the work and acceptance criteria]
   Site or place of work: [location]
   Start date and end date: [dates]
   Price and payment: [amount or pricing method, VAT treatment if known, invoice requirements and payment period]
   Programme and milestones: [dates and dependencies]
   Materials, equipment and access: [who supplies what]
   Changes and variations: [approval process]
   Subcontracting: [whether further subcontracting is allowed]
   Insurance: [required policies and limits if known]
   Health and safety: [site rules and responsibilities]
   Confidentiality and intellectual property: [requirements and ownership of deliverables]
   Data protection: [whether either party handles personal data and each party's role if known]
   Warranties, defects and rectification: [requirements]
   Delay, suspension and termination: [rights and notice periods]
   Liability and indemnities: [agreed positions or leave clearly marked as solicitor review points]
   Dispute resolution and governing law: [commercial preference, otherwise mark for solicitor review]
   Other requirements: [anything else]
   
   Produce a clear agreement with numbered clauses and a schedule for the services and payment terms. Use UK English and distinguish a company from a sole trader. Put every missing, ambiguous or legally sensitive issue in a prominent review list rather than guessing. Explain in plain English what each review point affects. Do not claim that the draft is legally suitable, compliant or ready to sign. Do not include invented company details, legislation references, insurance limits, tax treatment or liability caps.
