Worth checking yourself

Review volume: Low · 22

Profile status: Listed

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.
