Guide ranges for supply & fit; controls and commissioning by a smoke-control specialist. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.

Towns we list in Berkshire

Fitting across Berkshire means planning routes, access and lifting as well as the roof itself. Narrow lanes, shared driveways and town-centre parking restrictions all affect how a large unit is delivered and raised to roof level. We ask about these early so the quote reflects them. That approach is the same everywhere we work in England, from single domestic jobs to multi-unit commercial sites.

What we do on the day

Existing vent, actuator and upstand surveyed with the specialist
Controls, detection and wiring handled by the smoke-control specialist
Old vent removed with the stairwell kept protected below
Fire rules near escape routes — We check the roof around the vent for fire rules that affect it.
Upstand and weathering — We check the upstand suits the new vent and that the roof around it is sound.

Rules that apply in England

In England, smoke vents for common stairs must be certified to BS EN 12101-2, provide the free area the fire strategy requires (Approved Document B calls for at least 1 m² at the top of a common stair), and have backup power. Smoke vents have their own energy limit, commonly 3.5 W/m²K. Controls and commissioning are handled by a smoke-control specialist, and building control is involved where the system changes.

Common questions in Berkshire

Do commercial rooflights need planning permission?

Like-for-like replacements on commercial buildings rarely need planning permission. New or larger rooflights on non-domestic buildings and blocks of flats usually need checking with the planning authority, because householder permitted development rights don't apply. We tell you what we know about your building and point you to the right team.

Do you need scaffolding to fit a rooflight?

Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.

How long does fitting take?

Fitting a smoke vent rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.
