Straight advice on swapping glass only, and when it is worth it. Sealed unit replacement means changing only the glass in an existing frame.

Winter light and glass choice in Colne

By midsummer Colne has about 17 h 07 min of daylight, but in December only around 7 h 24 min, with the noon sun at about 13°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

Rules for glass-only replacement 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.

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

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 from Colne

Will heavier glass damage my hinges?

It can. Triple units are about 50% heavier, so hinges and packers are checked and upgraded where needed.

Can I put triple glazing in my existing windows?

Usually not in a way that helps. Most frames take up to about 28 mm units; a triple unit that thin performs about the same as, or worse than, good double glazing. We check your frames before recommending anything.

Do you fit triple glazed replacement sealed units in Colne?

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

Do I need permission for triple glazed replacement sealed units in Colne?

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.
