Flat rooflights for St Neots: the essentials
Our flat rooflights service in St Neots covers fixed double or triple glazed rooflights for flat roofs and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Flat rooflights suit landings, bathrooms and rear extensions with flat roofs.
St Neots is around 40 km from Peterborough, and we survey and fit throughout that part of Cambridgeshire, including the PE19 district.
Choices for your St Neots project
- Frame colours: anthracite, black, white or RAL
- Insulated kerb or timber upstand built to suit
- Rain sensor if paired with an opening unit
- Square, rectangular or long-format sizes
- Integral or fitted blinds
- Double or triple glazed with a warm-edge spacer
- Slim sightlines from inside — mostly glass, little frame
Before you order: points to check
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
- The roof membrane must be dressed up the upstand before the unit goes on
Planning, building control and St Neots
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Common 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.
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
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.
Is the survey in St Neots free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
