How do I choose a trustworthy glazier?

Compare the public evidence on each profile — how many independent reviews they have and across how many named platforms, the rating and how recent it is, any verified credentials, and the company record. A glazier backed by several named sources is harder to fake than one with a single listing.

Does MyTrustedTraders rank or recommend glaziers for payment?

No. There are no ads and no paid placement. Glaziers are ranked only by the strength of independent public evidence — no one can pay to rank higher, add a badge, or change their reviews.

Where do the reviews come from?

They're imported from named public review platforms and always shown with the source named — they aren't reviews written on MyTrustedTraders. We cross-check the same business across sources rather than creating new reviews.

What should I check before hiring a glazier?

Confirm credentials and insurance directly with the glazier, get a written quote, and run the Cowboy Checker on the business first. MyTrustedTraders helps you shortlist on the evidence — it doesn't replace your own checks before you hire.

How to judge a glazier

Independent, no-ads guidance — the trade-specific checks that matter most, the warning signs, and what to ask before you hire. Use it alongside each trader’s public evidence above.

Verify before you hire

Check the installer is on the FENSA, CERTASS, or ASSURE register — these are the government-authorised schemes that self-certify window replacement meets building regulations.
Confirm they offer an insurance-backed guarantee (IBG), which protects you if the company folds before or after the job.
For emergency call-outs, check recent reviews mention actual arrival times — not just the advertised promise.
If your home is in a conservation area or is listed, ask whether they have experience matching original glass or frame profiles to avoid planning enforcement.

Warning signs of a cowboy

A glazier who refuses to give a written quote before starting — especially at night or after a break-in — is a classic rogue-trader warning sign.
No mention of FENSA, CERTASS, or ASSURE membership for a planned window replacement means your job may not be building-regulations compliant.
Pressure to sign on the spot or pay cash in full upfront with no paperwork is a strong sign of a cowboy operator.
Trade logos or police 'Secured by Design' badges on a van or leaflet that you cannot verify on the scheme's own website have been used fraudulently.

Questions to ask before you hire

Are you registered with FENSA, CERTASS, or ASSURE, and will I receive a certificate after the job?
Does the job come with an insurance-backed guarantee, and which provider underwrites it?
For emergencies: what is your realistic arrival time from my postcode right now?
Do you carry public liability insurance, and can you show me proof before you start?
