Electric opening rooflight installation in Chalk Farm

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Chalk Farm is planned around the forecast rather than pinned to a date regardless of rain. The opening is kept covered whenever it is exposed, and a roof is not left open overnight without a proper temporary seal. That approach applies to every electric opening rooflight we install, from a new opening to a straight swap or a fit-only job. We cover Chalk Farm, the NW5 district and the rest of Greater London.

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.

Where our fitters travel

Chalk Farm and the districts around it, NW5, NW1 and NW3, all sit inside our working area. So does the ground between Chalk Farm and Camden Town (1 mile), and on towards Holloway (1 mile). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

Fit-only or supply and fit

If you have bought an electric opening rooflight yourself, we check four things before fitting. First, the delivery: open it, look for chips, cracks and bent frames, and report any damage to the seller straight away. Second, the size, measured against the builder's opening rather than the external frame. Third, the upstand height above the finished roof. Fourth, the maker's instructions, which set the fixings and sealing. Product warranty claims go to the seller and maker; our guarantee is for how it was fitted.

What we do on the day

  • Opening and closing tested, with controls explained at handover
  • Wall switch, remote receiver or control box fixed in place
  • Rain sensor positioned where it will get wet when rain starts
  • Opening onto a side slope — We check where the opening part will sit if the roof is pitched or the unit faces a neighbour.
  • Rain sensor position — We place the rain sensor where rain will reach it quickly and debris will not cover it.

How a fitting day runs

Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack an electric opening rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes one day, plus the electrician's connection.

Regulations for Chalk Farm properties

Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so replacements we fit are notified with a building notice, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.

Before you get in touch

A fast quote needs five things: a photo of the roof from outside, one from the room below, rough sizes of the opening or the space, the roof covering (felt, single-ply, fibreglass, tiles, slate or metal), and a note on access. If you have already bought the unit, add the product link or spec sheet. And give us the postcode, NW5 or a neighbouring district.

Common questions in Chalk Farm

How long does fitting take?

Fitting an electric opening 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.

Do you offer trade rates for builders and roofers?

We carry out subcontract fitting for builders, roofers, extension companies and commercial contractors. Pricing is per job or per schedule of units, agreed in writing before we start. We can work to your programme, fit on your upstand or build our own, and leave the opening ready for the next trade. Send drawings or a unit schedule and we will come back with a trade quote.

Can you fit the electric opening rooflight I bought online?

Yes, fit-only is one of our core services. Send the product link or spec, photos of the roof and rough sizes, and we can usually price it from those. Before fitting we check the delivery for damage, which should be reported to the seller, plus the size against the builder's opening and the upstand height. The product warranty stays with the maker or seller, and our guarantee covers the fitting.
