Triple glazed aluminium windows in Bedfordshire
We survey and fit triple glazed aluminium windows across Bedfordshire, from Luton and Bedford to smaller towns such as Kempston.

Slim sightlines and a powder-coated finish, with three panes of glass. Triple glazed aluminium windows use thermally broken aluminium frames, where an insulating strip separates the inside and outside of the frame, holding a three-pane sealed unit.

Rules in England
The rules for replacement windows in England are set by Approved Document L (2021 edition, with 2023 amendments): 1.4 W/m²K, or a Window Energy Rating of band B or better. Replacement windows are a controlled fitting. A competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council within 30 days; otherwise a building control body approves it.
Planning: Replacing windows on a house is normally permitted development if the new ones look similar. New upper-floor windows in a side wall must be obscure glazed and fixed, or open only above 1.7 m. Flats and maisonettes have no householder permitted development rights, so a change that alters their appearance needs planning permission. An Article 4 direction in a conservation area may mean permission is needed, and listed buildings need listed building consent.
How it works
You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.

Questions
Can aluminium windows take triple glazing?
Yes, and the strength of aluminium suits the extra weight. The system needs a glazing rebate deep enough for the unit, which we check on survey.
How much do triple glazed aluminium windows cost?
Our guide runs from £1,095 for a small window to £2,795 for a large one, fitted and inc VAT. UK quotes typically sit 20 to 35% above uPVC.
Do aluminium windows suit older houses?
They suit many 20th-century homes well. For Victorian and Georgian houses, or conservation areas, timber or heritage-style frames are usually a better match.
Do you cover all of Bedfordshire?
We arrange surveys and fitting across Bedfordshire.
Do I need permission for triple glazed aluminium windows in England?
In England, like-for-like replacements on a house are normally permitted development; flats need permission if the change alters their appearance, Article 4 areas may need permission, and listed buildings need listed building consent.
