Sun tunnel installation in Bicester

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Bicester 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 sun tunnel we install, from a new opening to a straight swap or a fit-only job. We cover Bicester, the OX26 district and the rest of Oxfordshire.

Coverage in and around Bicester

Looking at a property near Bicester but not quite in it? We work across OX26, OX6 and OX25 and outwards to Oxford, Cowley and Banbury. 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 Bicester.

Already bought your unit?

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 the job includes

  • Rigid or flexible tube run and joined, with as few bends as possible
  • Dome fixed and sealed on top of the flashing
  • Dust cleared from the room below and the loft
  • Rigid or flexible tube — We check whether a rigid tube will fit the route before falling back on a flexible one.
  • Length and bends in the tube — We plan the shortest, straightest route we can between the roof and the ceiling.

What happens on the day

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 a sun tunnel 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 half a day to a day.

Do you need permission in Bicester?

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.

Help us quote accurately

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 OX26 and we will come back with a quote or a survey date.

Common questions in Bicester

Can you fit the sun tunnel 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 opening, the flashing kit and the roof pitch. The product warranty stays with the maker or seller, and our guarantee covers the fitting.

Do I need planning permission for a rooflight in Bicester?

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.

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.
