Rules for uPVC 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

We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.

  • 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 Gainsborough

Do I need trickle vents?

In England and Wales, if your old windows had trickle vents, the new ones must have vents at least as big, and if they did not, the room must be no less ventilated than before. Scotland and Northern Ireland also require that replacement windows do not make ventilation worse. We size vents on the survey.

How much more is triple glazed uPVC than double?

Usually 20 to 30% more for the same window, though quotes in the UK range from about 15 to 40%. The written quote shows the triple price, and we can price double glazing alongside it if you want to compare.

Do you fit triple glazed uPVC 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.

Do I need permission for triple glazed uPVC windows in Gainsborough?

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.
