Rules in England
England requires replacement windows to achieve 1.4 W/m²K, or a Window Energy Rating of band B or better, which good triple glazing passes comfortably. 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
The surveyor measures every opening, checks ventilation, escape windows and safety-glass zones, and talks through styles. Your written quote lists each item with its glass build-up and U-value, and the price is fixed for that specification.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
Questions
How much extra is acoustic glass?
Comparing our guide prices, acoustic glass adds about £50 to £200 a window, inc VAT, depending on size.
Will acoustic glazing block all traffic noise?
No glazing makes a room silent. Well-specified acoustic glazing makes a clear, noticeable reduction, especially in the low rumble of traffic.
Do trickle vents let noise in?
Standard vents can. Acoustic trickle vents are designed to keep ventilation while reducing sound.
Do you cover all of Northamptonshire?
We arrange surveys and fitting across Northamptonshire.
Do I need permission for acoustic triple glazing in England?
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.
