Winter light in Hertford
Southern England has the UK’s highest winter sun angles, about 15° at midday in Hertford in late December. Big south-facing windows here can make good use of a higher solar-gain triple unit.
Rules 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
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

Questions
Which frame is best for a house in Hertford?
It depends on the house rather than the town: uPVC for value, aluminium for slim frames and big panes, timber for period homes, alu-clad timber for low upkeep. Our surveyor will talk through the options.
Are there grants for triple glazing in England?
Rarely. Most schemes fund insulation and heating before glazing. See our regulations and funding guide for the current position.
Do I need planning permission in Hertford?
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 before changing the style.
How much does triple glazing cost in Hertford?
Our guide prices are the same UK-wide: triple glazed uPVC windows from £695 each and a 3-bed semi from £9,395, fitted and inc VAT.
