uPVC frames give the best heat-loss figure for the money, in white or woodgrain. Triple glazed uPVC windows are plastic-framed windows fitted with a sealed unit of three glass panes and two gas-filled cavities.

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

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 Berkhamsted

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 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.

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

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 uPVC windows fitted in Berkhamsted?

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