Flat rooflights for Hailsham: the essentials
Our flat rooflights service in Hailsham 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.
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.
Hailsham sits about 11 km from Eastbourne and 15 km from Seaford, and we cover the whole BN27 postcode district and the roads in between.
What you can choose
- Solar-control or self-cleaning outer pane
- Frame colours: anthracite, black, white or RAL
- Rain sensor if paired with an opening unit
- Insulated kerb or timber upstand built to suit
- Integral or fitted blinds
- 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
Consents for flat rooflights in Hailsham
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
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.
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.
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.
Is the survey in Hailsham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
