What to check when hiring window / door fitters in City of London

MyTrustedTraders ranks on independent public evidence. No ads, no paid placement. Use these checks alongside the evidence on each profile before you decide who to contact.

  • Be wary of high-pressure 'today-only' discounts and a salesperson who won't leave. A reputable window or door firm gives you a written, itemised quote you can take away and compare against others.
  • Never pay the full price up front; a modest deposit with the balance on completion is normal. Ask what deposit protection or insurance-backed guarantee you get if the firm stops trading before fitting.
  • Get the specification in writing (frame material, the glazing units and their energy rating, and any trickle vents) so you can check you got what you paid for.
  • Replacement windows and external doors must be signed off as meeting building regulations. Use an installer registered with FENSA or CERTASS so they self-certify the work and give you the certificate you'll need when you sell.
  • Look for consistent reviews across several named sources, not one polished profile.
