Winter light and glass choice in Margate

Rules for glass-only replacement in England

The rules for replacement windows in England are set by Approved Document L (2021 edition, with 2023 amendments): 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.

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.

  • 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 Margate

Why are my windows misting between the panes?

The seal around the unit has failed and moist air has got in. Only replacing the unit fixes it.

Can I put triple glazing in my existing windows?

Usually not in a way that helps. Most frames take up to about 28 mm units; a triple unit that thin performs about the same as, or worse than, good double glazing. We check your frames before recommending anything.

Do you fit triple glazed replacement sealed units in Margate?

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

How long does it take to get triple glazed replacement sealed units fitted in Margate?

After the survey, typical manufacture time is 1 to 2 weeks for units, and replacing the units usually takes a few hours to a day.
