Winter light and glass choice in Gainsborough

Rules for 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.

Before ordering: 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 Gainsborough

Do timber windows need planning permission?

Replacing like-for-like windows on a house is normally permitted development, but conservation areas, Article 4 directions and listed buildings have their own rules. See our planning guide.

Are timber windows warmer than uPVC?

They can be. Timber insulates well, and a deep timber frame with triple glass reaches whole-window U-values around 0.8 to 1.1, similar to good uPVC.

Do you fit triple glazed timber windows in Gainsborough?

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

How long does it take to get triple glazed timber windows fitted in Gainsborough?
