New rooflight in an existing roof in Pimlico

Already bought a new rooflight, or still deciding which one to get? Both are fine. For new rooflight openings in Pimlico we either source a suitable unit and install it, or fit the one waiting in your garage. Fit-only jobs are usually priced from your photos and measurements, while supply-and-fit and replacement jobs get a free survey first. Whichever route you take, the opening, the upstand or flashing, and the delivery are checked before anything is fixed down. Properties in SW1V and the surrounding districts are covered on the same terms.

Fitting across Pimlico and nearby

Looking at a property near Pimlico but not quite in it? We work across SW1V, SW1 and SW1P and outwards to Battersea, Chelsea and Soho. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Pimlico.

What we check on a supplied unit

There are two ways to do this. Supply and fit means we source a new rooflight that suits your roof and install it, so one company answers for both the product choice and the fitting. Fit-only means you buy the unit and we install it. With fit-only, the product warranty stays with the maker or seller, and our written guarantee covers the fitting work. Both routes get the same checks on the opening, the upstand and the maker's instructions before anything is fixed.

Included in the work

  • Plasterboard reveals formed inside and left ready for skim or decoration
  • Rooflight fitted, sealed and checked for even clearance on every side
  • Opening marked out, covering stripped back and the deck cut cleanly
  • Planning for your roof — We check whether the new rooflight falls within permitted development for your house and nation.
  • Cables, pipes and ceiling fittings — We look into the ceiling void for anything in the way of the new opening.

From arrival to clean-up

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a new rooflight: two to three days, weather permitting.

Regulations for Pimlico properties

England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.

Details that speed up your quote

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, SW1V or a neighbouring district.

Common questions in Pimlico

Do I need planning permission for a rooflight in Pimlico?

Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in England. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.

Will my new rooflight leak?

A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out 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.
