How we approach flat rooflights in Bognor Regis
For Bognor Regis 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Bognor Regis, as anywhere, flat rooflights are the usual choice for kitchen extensions, side returns and flat-roofed back rooms.
From Bognor Regis to Chichester, Littlehampton and Worthing, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Integral or fitted blinds
- Solar-control or self-cleaning outer pane
- Insulated kerb or timber upstand built to suit
- Rain sensor if paired with an opening unit
- Square, rectangular or long-format sizes
- Slim sightlines from inside — mostly glass, little frame
- 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 Bognor Regis
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.
See our building regulations guide for U-values, glazing limits and self-certification.

How the job runs
- Tell us what you have. Send the PO21 postcode, a rough size and a couple of photos.
- Measure and check. A surveyor visits Bognor Regis, measures and checks structure and access.
- Agree the quote. You approve the specification and price before anything is ordered.
- Installation day. Usually one day into a prepared opening, longer for new openings.

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.
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.
Do I need to be at home for the survey in Bognor Regis?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Bognor Regis free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
