How we approach flat rooflights in Stratford
Flat rooflights in Stratford means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the E15 district and the rest of Greater London, with a survey before any price is fixed.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Think of flat rooflights for landings, bathrooms and rear extensions with flat roofs.
Stratford sits about 1 km from Bow and 3 km from Hackney, and we cover the whole E15 postcode district and the roads in between.
What you can choose
- Plastered or lined internal reveal
- Frame colours: anthracite, black, white or RAL
- Integral or fitted blinds
- Insulated kerb or timber upstand built to suit
- Double or triple glazing
- Inner pane laminated for safety overhead
- Slim sightlines from inside — mostly glass, little frame
Before you order: points to check
- The roof membrane must be dressed up the upstand before the unit goes on
- New openings in an existing roof need a structural check on joists
Planning and building rules for Stratford
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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
Will it make the room too hot?
A big unglazed-to-sky area can add solar gain in summer. Solar-control glass, a blind, or pairing a fixed unit with an opening one keeps it comfortable.
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 Stratford free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Stratford?
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.
