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.

  • Free survey and a written quote fixed for the specification
  • Glass build-up and whole-window U-value on every quote
  • Written handover pack at the end of the job
  • Guarantees on frames, units and fitting in writing

Questions from Corby

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.

Is alu-clad timber worth the extra cost?

It is for many self-builders and people planning to stay for decades, because the outside needs almost no upkeep and the timber inside looks warm. For a quick replacement on a typical semi, uPVC or aluminium give better value.

Do you fit alu-clad timber triple glazed windows in Corby?

Yes. We arrange surveys and fitting in Corby and across Northamptonshire. Send your postcode and the windows or doors you want replaced, and we will book a free survey.

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

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.
