Check five things: a Class A profile under BS EN 12608, a Window Energy Rating of A or better, PAS 24 security testing, neat welds with smooth hardware, and a written guarantee from a Certass or FENSA registered installer. Price alone is not a reliable guide.
How can you judge quality in person?
- Corners should be cleanly welded with no gaps
- Sashes should close without forcing and sit evenly in the frame
- Handles and locks should feel firm, not loose
- Glass should be clear with no misting between panes
What should the paperwork show?
A Building Regulations certificate, the profile and glass specification, and a written guarantee that says who stands behind it and for how long.
Is a more expensive window always better?
No. Compare like for like on the profile, glazing, hardware and guarantee. See our uPVC windows. Wednesfield Trade Windows is a family-run firm fitting TruFrame windows, and as a Certass registered installer it certifies each job against the Building Regulations.
What are the red flags when choosing an installer?
- Vague specifications or refusal to name the profile system
- No Building Regulations certificate or competent person registration
- No written guarantee, or one that excludes the glass
- Pressure to sign on the day
