Commercial aluminium windows

Aluminium windows for commercial buildings and the upper floors above shops, fitted across the UK. They suit offices, flats over shops and mixed-use buildings where the existing windows have failed. Prices depend on size, opening type and glazing, and are quoted after a survey.

Consents this work tends to involve

  • Planning permission
    Often needed

    A change in material, glazing pattern or opening style on a commercial building often needs permission, and more often in a conservation area.

  • Listed building consent
    Sometimes

    Replacing historic windows on a listed building, which councils frequently resist.

  • Building regulations
    Usually needed

    Replacement windows are controlled work: energy performance, safety glazing and, in some rooms, escape and ventilation.

An installer’s general guide; your council decides.

Why do upper-floor windows matter on a shopfront job?

Because the street reads the building as one thing. A shopfront that lines up with the windows above sits in its terrace; a new front under a row of mismatched upper windows looks bolted on. Councils assessing a shopfront often look up.

Does an Article 4 direction affect commercial windows?

Article 4 directions remove permitted development rights, and they are most often used for houses. A commercial building has fewer such rights to begin with, so window changes on it usually need permission anyway. Flats above shops are where it gets complicated — check the council’s Article 4 map for your street.

Questions

Do replacement windows on a shop need building control?
Yes, replacement windows are controlled work. A registered competent person can self-certify some window installations; otherwise building control is notified. Ask how your installer will certify the work before it starts.
