Sun tunnel installation in Allerton

Already bought a sun tunnel, or still deciding which one to get? Both are fine. For sun tunnel installation in Allerton 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 L19 and the surrounding districts are covered on the same terms.

Coverage in and around Allerton

Jobs across L19, L18 and L25 are part of our normal cover for Allerton. 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 Garston and Halewood are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Buying your own, or letting us supply

Your unit or ours, the fitting standard is the same. For supply and fit we choose a sun tunnel to suit the roof and price it with the installation. For fit-only we work with what you have, after confirming it arrived undamaged, that it matches the builder's opening, and that the upstand will sit at the height the maker asks for. Report any transit damage to the seller, as the product cover is theirs and the maker's. Our written guarantee applies to the fitting itself.

What we do on the day

  • Route through the loft checked for joists, cables and pipes
  • Ceiling opening cut neatly and the diffuser fitted
  • Roof opening cut and the flashing fitted to tiles, slates or a flat-roof kit
  • Tube size — We match the tube size to the room and the roof.
  • Flat or pitched roof kit — We confirm the roof type and covering before ordering the kit.

How a fitting day runs

Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a sun tunnel runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.

Planning, building control and Allerton

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.

Getting a price from photos

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 L19 and we will come back with a quote or a survey date.

Common questions in Allerton

Can you remove and dispose of the old rooflight?

Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.

Do you cover Allerton?

Yes. Fitters travel to addresses in Allerton and the surrounding districts, including L19. 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.

Can you fit a rooflight in winter or when it is raining?

Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.
