Rules for alu-clad timber windows in England

In England, replacement windows must meet 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

After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.

Questions from Islington

Do alu-clad windows suit Passivhaus builds?

Many alu-clad systems are designed for low-energy homes. If you need Passive House Institute certified components, ask and we will price systems that hold that certification.

Can I choose different colours inside and out?

Yes. The aluminium can be any RAL colour and the timber inside can be natural, stained or painted.

How long does it take to get alu-clad timber triple glazed windows fitted in Islington?

After the survey, typical manufacture time is 8 to 12 weeks, and most homes are fitted in 1 to 4 days.

Do I need permission for alu-clad timber triple glazed windows in Islington?

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. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
