Winter light across Northumberland
Our 8 local town pages in Northumberland run from Hexham in the south to Berwick-upon-Tweed in the north. On the shortest day, daylight ranges from about 7 h 00 min in Berwick-upon-Tweed to 7 h 10 min in Hexham, and the midday sun reaches between 11° and 12°.
Blyth is far enough north that the December sun barely clears 11° at midday, with only about 7 h 08 min of daylight. Long, dark winters are where triple glazing’s lower heat loss matters most.

Rules 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
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.
- Guide prices published, not hidden
- No pressure: the quote is yours to keep
- Frames, glass and fitting in one contract
- Advice on planning and consents before you order
