Step 1 — Complain to the builder (in writing, dated)
One page: what was agreed, what went wrong (dated facts), what you want, a 14-day deadline. The full structure: letter before action. Keep proof of posting and every reply.
Step 2 — Report to Trading Standards
London Borough of Islington Trading Standards
Trading Standards page verified live (HTTP 200) during the 2026-09-04 bulk council wave. Consumer complaints reach the team via the Citizens Advice consumer service. The council's Trading Standards page: https://www.islington.gov.uk/advice/consumer-advice (verified 2026-09-04). Complaints are triaged nationally: the Citizens Advice consumer service passes your report to this council.
Step 3 — Protect your money in parallel
Trading Standards does not recover money. In parallel: the money-back route map — card section 75, chargeback, then small claims.
Evidence while you wait
The evidence file — contract, payments, dated photos, full message threads. Project-specific: extensions, loft conversions, roofing, kitchens, bathrooms, driveways.
