Planning and building rules in England
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Common questions
Do you cover all of Lancashire?
Yes. We survey and fit across Lancashire, including Preston, Burnley and Blackburn. Remote and island addresses are by arrangement.
Do I need planning permission for a rooflight in Lancashire?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof.
Is the survey free?
Yes, for new installations. Repair and maintenance visits are charged, and we tell you the visit price first.
Do you work on commercial buildings?
Yes — offices, schools, warehouses and retail, including smoke vents and fragile-roof replacements, with safe access planned.
Can I cancel?
Made-to-measure products are excluded from the statutory 14-day cancellation right, but you can cancel without charge until we place the order with the manufacturer. Our terms explain the rest.
