Fit-only rooflight installation in Blackheath

Already bought a rooflight, or still deciding which one to get? Both are fine. For fit-only rooflight installation in Blackheath 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 SE3 and the surrounding districts are covered on the same terms.

Fitting across Blackheath and nearby

Jobs across SE3, SE13 and SE10 are part of our normal cover for Blackheath. 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 Lewisham and Greenwich 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 check on a supplied unit

There are two ways to do this. Supply and fit means we source a 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.

On the day, we cover

  • Check of the delivered unit, glass, fixings pack and instructions before work starts
  • Opening tested where relevant, packaging taken away and paperwork handed back
  • Upstand height, level and fall checked, and squareness confirmed across the diagonals
  • Upstand height above the roof — We measure how far the upstand stands above the finished roof surface, including any ballast or walkway.
  • Warranty conditions on your unit — We read the warranty terms that came with your rooflight before we fit it.

Fitting your rooflight, step by step

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 rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Planning and building rules in England

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.

Getting a price from photos

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in SE3, and we can price it.

Common questions in Blackheath

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 cover Blackheath?

Yes. Fitters travel to addresses in Blackheath and the surrounding districts, including SE3. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.

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.
