What do conservation rooflights in Grantham involve?
Thinking about conservation rooflights in Grantham? The short answer: slim, low-profile steel-look rooflights for period and listed roofs. The longer answer depends on your roof, which is why we survey before we price.
Older terraced streets in Midlands towns often have back additions and side passages that suit a ridge rooflight or long flat rooflight. In Grantham, as anywhere, conservation rooflights are the usual choice for period, listed and conservation-area roofs.
Grantham is around 36 km from Lincoln, and we survey and fit throughout that part of Lincolnshire, including the NG31 district.

Do you need permission in Grantham?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.
