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.

Towns we list in County Antrim

Coverage in County Antrim works by postcode, not by distance from an office. Give us the full postcode and we will confirm whether it is standard cover, as it is for most of Northern Ireland, or one of the few remote and island areas handled by arrangement. Either way, you get a written quote before any work is booked, with travel included in the price.

Rathlin Island is covered by arrangement, with travel priced into the quote before you commit.

What's included

Cable route and controls set up ready for the electrician's final connection, quoted as a separate line
Rain sensor positioned where it will get wet when rain starts
Unit fitted, sealed and weathered like a fixed flat rooflight
Who makes the final connection — We confirm who will connect the rooflight to the mains before booking.
Rain sensor position — We place the rain sensor where rain will reach it quickly and debris will not cover it.

Rules that apply in Northern Ireland

In Northern Ireland, the energy standard for a new or replacement rooflight or roof window in an existing home is WER Band C or a U-value of 1.6 W/m²K, under Technical Booklet F1. Cutting a new opening alters the roof structure, so a building control application is expected; confirm with the council's building control team. Planning permitted development covers many rooflights on houses if they stay below the ridge, project no more than 15 cm on a road-facing slope and sit at least 0.5 m from the ridge, eaves and verges.

Common questions in County Antrim

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.

What upstand height and roof pitch does electric opening rooflight fitting need?

It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.

Can you replace an old dome without redoing the whole roof?

Usually, yes. If the existing kerb is sound, level and tall enough, a new unit can often sit on it with a fresh seal to the roof covering. If the kerb is rotten or too low, we rebuild it and patch the covering around it rather than stripping the whole roof. This is checked at the survey and included in the written quote, so you know the full scope first.
