What do flat rooflights in Basingstoke involve?
For Basingstoke homes and buildings we offer flat rooflights: fixed double or triple glazed rooflights for flat roofs and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Typical uses for flat rooflights include landings, bathrooms and rear extensions with flat roofs.
Basingstoke is around 46 km from Southampton, and we survey and fit throughout that part of Hampshire, including the RG21 district.
Options we can specify in Basingstoke
- Double or triple glazing
- Integral or fitted blinds
- Insulated kerb or timber upstand built to suit
- Solar-control or self-cleaning outer pane
- Rain sensor if paired with an opening unit
- Fixed units are simple, quiet and low-maintenance
- Pairs with an opening unit where you also need ventilation
What to check first
- The roof membrane must be dressed up the upstand before the unit goes on
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
Planning, building control and Basingstoke
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. 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.
Read the planning permission guide before you commit to a design.

Flat rooflights in Basingstoke: questions
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
Can a flat rooflight be walked on?
Not unless it is designed as a walk-on unit with structural laminated glass. A standard flat rooflight is for light only — if the roof is used as a terrace, choose a walk-on rooflight instead.
Double or triple glazing?
Double glazing suits most domestic jobs. Triple glazing improves thermal performance and cuts noise from rain, which is worth it over bedrooms or where the energy calculation is tight.
Is the survey in Basingstoke free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Basingstoke?
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.
