Winter light in Welling
Welling sits in the milder south of the UK, so the heating season is shorter than further north, but winter days are still short: about 7 h 50 min of daylight on 21 December. Triple glazing pays back most here on north-facing and shaded rooms.
Rules 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
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.
- 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
Do you fit triple glazing in Welling?
Yes. We arrange surveys and fitting in Welling and the DA16 district. Send your postcode and what you need, and we will book a free survey.
Do I need planning permission in Welling?
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.
Which frame is best for a house in Welling?
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.
How much does triple glazing cost in Welling?
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.
