Aluminium glazing is a considered purchase, and prices swing widely because the specification does. Understanding the cost drivers lets you compare quotes on value, not just headline figures — and stops the cheap-looking quote from becoming the expensive mistake.
What moves the price
Size and glass area, the number of leaves, the glazing spec (acoustic, solar control, triple), the security rating, the finish (dual-colour costs more) and the threshold detail all move the number. A flush threshold and a PAS 24 build-up cost more up front and are usually worth it.

Compare like for like
The classic trap is comparing a bare-bones quote against a fully specified one. Line up the whole-door Uw, the security rating, the threshold type and the warranty before you judge on price. Our supplier guide lists the exact questions to ask.
Local supply and fit
Buying locally means the surveyor and fitter know the area's housing stock and can service the doors afterwards. Homeowners across the county can get a properly surveyed quote rather than a phone estimate — including in towns like St Albans and Hemel Hempstead.
Budget for the whole job
Remember the price includes structural work, making good and sometimes a steel head, not just the doors. A transparent supplier itemises this so there are no surprises on the final invoice.
