Websites & marketing for glaziers and window fitters
There are 4,160 glazing firms registered in the UK, and the number has risen 31.2% since 2021. Here is how they win customers online, and what a glazier’s website needs to do.
Glazing splits into two very different customers. One has a broken pane or a failed seal and needs help soon. The other is planning replacement windows or doors, researches carefully and compares quotes.
A glazier's website needs to serve both: make urgent repairs easy to request, and give planned jobs the photos, product information and reassurance that justify a larger decision.
The UK market for glazing firms
The number grew 31.2% between 2021 and 2026, well ahead of the +0.8% for UK businesses overall, so more firms are competing for the same customers.
95% of them have fewer than 10 employees, 15% are sole proprietors and 81% are limited companies. Most are small operations, so a clear, quick website is a genuine way to stand out from competitors who have not looked after theirs. The ten areas with the most firms hold about 24% of the UK total.

What a glazier’s website needs to do
- Emergency glass repair and boarding-up availability stated plainly, with a tap-to-call number
- Pages for each main product or service (replacement windows, doors, glass repair, sealed unit replacement)
- Any competent-person scheme registration you hold, such as FENSA, shown only if it is true
- Honest information on guarantees: only state what you offer
- Photos of finished installations and genuine reviews
- A quote form that accepts photos and rough measurements
Mistakes we see
- One page covering both urgent repairs and planned replacements
- Guarantee claims that you cannot back up
- No clear way to ask for an urgent visit
- Product pages with no photos of real installations
How we would approach it
- Bespoke web design. Separate paths for urgent repairs and planned replacements make the site easier to use.
- SEO. Customers search for the exact job, such as window replacement, in their area.
- Meta and Google ads. Search ads can catch urgent repairs, and social ads can promote planned replacements.
