Warmer front rooms on 1930s and Victorian homes. A bay window projects out from the wall in angled sections; a bow window curves in more, shallower sections.

Winter light and glass choice in Daventry

Winter days in Daventry are short: about 7 h 41 min of daylight on 21 December, with the sun peaking near 14°. That low angle reaches deep into south-facing rooms, so we match the glass to each elevation rather than using one spec for the whole house.

Rules for bay and bow 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

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.

Questions from Daventry

Can I change a bay to a flat window?

That is a structural and planning change, not a like-for-like replacement. Ask and we will explain what it involves.

Do bay windows need bay poles?

If the old frames carry load from above, yes. We check on survey and include support in the quote where needed.

Do I need permission for triple glazed bay and bow windows in Daventry?

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 bay and bow windows fitted in Daventry?

After the survey, typical manufacture time is 5 to 8 weeks, and most homes are fitted in 1 to 4 days.
