Before you pay a deposit
Being registered at Companies House means a company exists — it doesn't mean your quote is safe or your deposit is protected. Here's what a BYP check actually covers.
Search the directory for your insulation installer's company name. Then run a BYP check — enter their name, trade, and location. No account needed.
Companies House status, trade body membership, director history, dissolved companies — all cross-matched against the name and town on your quote.
Large upfront deposits, cash-only demands, no written contract — we flag the patterns that appear in 9 out of 10 rogue trader prosecutions.
What you get back
A clean result lets you pay with confidence. And if something needs a closer look, you'll know exactly what to ask — before any money changes hands, not after.
A two-minute check on any UK trader — so handing over a deposit feels like an easy decision.
