Rules for sash 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 Milton Keynes

Will triple glazing make my sashes heavy to lift?

The balances are sized for the sash weight, so they should slide smoothly. Heavier sashes use stronger balances or weights.

Can I keep my original sash boxes?

Sometimes. A timber specialist can fit new sashes into sound original boxes, but the glass thickness is limited by the sash depth.

Do I need permission for triple glazed sash windows in Milton Keynes?

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.

How long does it take to get triple glazed sash windows fitted in Milton Keynes?

After the survey, typical manufacture time is 6 to 10 weeks, and most homes are fitted in 1 to 4 days.
