Triple glazed casement windows for homes in Haywards Heath: measured on a free survey, made to order and fitted by installation teams working for us across West Sussex.

Winter light and glass choice in Haywards Heath
By midsummer Haywards Heath has about 16 h 33 min of daylight, but in December only around 7 h 55 min, with the noon sun at about 16°. 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 casement windows 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.
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.
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 from Haywards Heath
Do casement windows need trickle vents?
If the old windows had them, yes, and at least as large. If not, ventilation must be no worse than before. We size this on survey.
Are triple glazed casements harder to open?
They are a little heavier, but with correctly sized hinges they open and close smoothly.
How long does it take to get triple glazed casement windows fitted in Haywards Heath?
After the survey, typical manufacture time is 4 to 6 weeks in uPVC, and most homes are fitted in 1 to 4 days.
