A written building contract protects both homeowner and contractor. Without one, disputes about scope, price and quality are very hard to resolve.

• Building Regulations approval required for most structural works
• Planning permission is separate — not covered by this contract
• Contractor must carry public liability insurance
• Retention is common (e.g. 5% held for 6 months)
• Consumer Rights Act 2015 implies quality standards
