Smoke vent rooflight installation in Bath

Glass is heavy, and bigger units get heavy fast. Fitting a smoke vent rooflight in Bath means planning how it travels from the delivery vehicle to the roof without chipping an edge or straining a back. Smaller units go up by hand with two fitters. Larger ones may need a hoist, a scaffold loading bay or a crane, and we tell you at quote stage if that applies. Once it is up, the fitting follows the maker's sequence: seat, fix, seal, finish. We take on work like this across Somerset.

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.

Covering BA1 and neighbouring districts

Jobs across BA1, BA2 and BS31 are part of our normal cover for Bath. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Keynsham and Trowbridge are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

What we do on the day

  • Existing vent, actuator and upstand surveyed with the specialist
  • Commissioning and sign-off carried out by the specialist before handover
  • Old vent removed with the stairwell kept protected below
  • Free area at the stair head — We check the free area the vent must provide before choosing a replacement.
  • Controls and backup power — We confirm the controls, detection and backup power are being dealt with by a specialist.

What happens on the day

On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a smoke vent rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Planning, building control and Bath

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.

Details that speed up your quote

What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around BA1 and we will come back with a quote or a survey date.

Common questions in Bath

Can you remove and dispose of the old rooflight?

Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.

Who is responsible for the smoke-control system?

The building's responsible person, duty holder or managing agent, depending on the nation, is responsible for keeping fire safety systems working. Our part is the rooflight and roof work; the controls, detection and commissioning are handled by a smoke-control specialist, and the quote says who does what.

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.
