## Before you hire a window / door fitter
_What to check when choosing this kind of trade (general guidance, not a claim about this business):_
- 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.
