UK Sealed Units Ltd is a London-based glazing manufacturer supplying premium, made-to-measure glazing products direct to homeowners, builders, and trade customers across the UK.
We manufacture everything ourselves — from flat roof skylights and frameless Juliet balconies to bespoke glass units, replacement sealed units, windows, doors, and shower glass. By selling direct from our London facility, we cut out the middlemen and pass the savings on — without ever compromising on materials, safety standards, or craftsmanship.

Our Story
UK Sealed Units Ltd was founded by glazing specialists who saw a gap in the market: customers were paying over the odds for made-to-measure glazing because of long supply chains and unnecessary intermediaries.
We built the business to fix that — combining in-house manufacturing with a direct-to-customer model that keeps prices fair and quality uncompromised.
- ✔ Owner-operated — you deal with the people who make your glass
- ✔ Every order personally reviewed and quality checked before dispatch
- ✔ No call centres — fast, direct communication on every enquiry
- ✔ London-based, serving the whole of the UK
