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.
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.

Questions from Northampton
Will triple glazed uPVC windows look bulky?
The frames look much the same as good double glazed uPVC. The glass unit is thicker, but that sits inside the frame, so from outside the difference is hard to spot.
Can I have coloured uPVC triple glazing?
Yes. Woodgrain and solid-colour foils are available on the outside, inside or both. Colour adds to the price and can add a week or two to the lead time.

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