Electric opening rooflight installation in Falmouth

If the electric opening rooflight on your roof now is misted, discoloured, cracked or letting water in, replacing it is often simpler than people expect. The old unit comes out, we inspect the kerb or frame underneath, and we decide with you whether it can be reused or needs rebuilding. Then the new one goes in, sealed to the roof covering and finished inside. We handle this kind of electric opening rooflight installation in Falmouth and nearby, alongside new openings and fit-only work. Postcode TR11 and its neighbours are all within our cover.

Guide ranges for supply & fit; the electrician's final connection is quoted separately. 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 TR11 and neighbouring districts

If you also own a property or a business unit in Truro, Redruth or Camborne, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and TR11, TR10 and TR3 sit comfortably within that pattern.

Already bought your unit?

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack an electric opening rooflight, photograph it, and tell the seller about any cracks or scuffs, because claims are much easier made early. We will also ask for the model or a link, so we can read the maker's instructions and check the builder's opening size and the upstand height it expects. If everything lines up, we fit it. If not, we explain what needs changing first.

What we do on the day

  • Opening and closing tested, with controls explained at handover
  • Cable route planned through the kerb or reveal before the lining goes on
  • Upstand checked or built to suit the unit and its actuator housing
  • Who makes the final connection — We confirm who will connect the rooflight to the mains before booking.
  • Cable length and size — We check the cable run against the maker's limits before planning where the controls go.

From arrival to clean-up

Where a job takes one day, plus the electrician's connection, the split is usually structural work first and finishing second. Early on, the fitters cut or prepare the opening, trim where needed and prepare the upstand or flashing. Then an electric opening rooflight is lifted in, fixed and made weathertight so the roof is sound before anyone moves inside. Plasterboard, trim and filler for the reveal come after. Each evening the work area is swept, and at the end the glass is cleaned and the team talks you through what was done.

Do you need permission in Falmouth?

Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.

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 TR11 and we will come back with a quote or a survey date.

Common questions in Falmouth

Does a rooflight need building regulations approval?

A new opening usually needs building regulations approval. A replacement is a controlled fitting: it must be self-certified by an installer registered with a competent person scheme or notified to building control. We are not registered with a scheme, so replacements we fit are notified to building control with a building notice, and the council's fee is shown on your quote.

Do you make good inside after fitting?

Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.

What if my roof opening is the wrong size for the electric opening rooflight?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.
