Building Job Contract Template for UK Tradespeople: What to Include
A clear written contract is not just good practice for UK tradespeople — it is legally recommended and, for domestic premises work, subject to specific consumer protection regulations. Here is what needs to go in a building contract and how to make contracting a standard part of your workflow.
Consumer Rights Act 2015
For contracts with domestic customers, the Consumer Rights Act 2015 requires that the service is performed with reasonable care and skill, within a reasonable time, and at a reasonable price (if not fixed in advance). A written contract with a clear scope, price, and timeline is your best evidence that you met these obligations if a dispute arises. The GOV.UK consumer rights guidance covers what customers are entitled to claim if work falls below standard.
What Your Contract Should Include
Your full business name and contact details, company registration number if applicable. Customer’s name and property address. Detailed description of the works — what is included and what is not. Materials specification. Fixed price or rate basis, and payment terms (typical: deposit, interim payments for longer jobs, final payment on completion). Start date and estimated completion. How changes to scope will be handled (change orders). Your insurance details. Dispute resolution process. The Federation of Master Builders provides standard contract templates for members.
Deposits: Reasonable Amounts and Protecting Yourself
Deposits of 10–25% are standard for UK building work. For larger jobs requiring significant materials purchase upfront, staged payments tied to project milestones are the norm. Avoid requesting large deposits from customers you have not worked with before — it raises red flags and creates unnecessary trust risk on both sides.
When Things Go Wrong
A clear written contract is the foundation for resolving disputes. Most disputes in UK building work arise from undocumented scope changes. The discipline of issuing written change orders for anything beyond the original scope — signed by both parties before additional work starts — prevents the majority of disagreements. HSE construction guidance also covers the health and safety obligations that form part of your legal duties on site.
