Flat rooflights for Ipswich: the essentials
We handle flat rooflights across Suffolk, including Ipswich. In short: fixed double or triple glazed rooflights for flat roofs and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
In the East of England, bungalows and chalet bungalows with large flat-roofed extensions are common, and they often suit a long run of rooflights. Flat rooflights suit landings, bathrooms and rear extensions with flat roofs.
Ipswich is the main town we list in Suffolk; we also cover nearby Harwich and Felixstowe.
Specification options
- Double or triple glazing
- Rain sensor if paired with an opening unit
- Plastered or lined internal reveal
- Frame colours: anthracite, black, white or RAL
- Solar-control or self-cleaning outer pane
- Inner pane laminated for safety overhead
- Pairs with an opening unit where you also need ventilation
Before you order: points to check
- The roof membrane must be dressed up the upstand before the unit goes on
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
Planning, building control and Ipswich
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
Read the planning permission guide before you commit to a design.

Common questions
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.
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.
Will I need planning permission in Ipswich?
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.
How do I book a survey in Ipswich?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
