Loft conversion roof windows in Thatcham

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Thatcham 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 loft roof window we install, from a new opening to a straight swap or a fit-only job. We cover Thatcham, the RG19 district and the rest of Berkshire.

Guide ranges for supply & fit. 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.

Covering RG19 and neighbouring districts

Fitters travel to the job, so the address is what counts. In Thatcham that means postcode districts RG19, RG18 and RG14, and the same teams can just as easily take on work in Newbury, about 3 miles away, or Tadley at roughly 7 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

Already bought your unit?

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a loft roof window, photograph it, and tell the seller about any cracks or scuffs, because claims are much easier made early. We will also ask for the model or a link, so we can read the maker's instructions and check the opening size and the flashing kit it expects. If everything lines up, we fit it. If not, we explain what needs changing first.

Included in the work

  • Linings fitted, ready for the plasterboarder or decorator
  • Insulation collars fitted so the room's insulation meets each frame
  • Underlay dressed and taped around every frame
  • Energy performance in a loft — We check every window meets the energy limit for roof windows in existing homes.
  • Approved loft drawings — We work to the window positions on your approved loft drawings or agree changes with your builder first.

Fitting your loft roof window, step by step

Morning first: the team arrives, introduces itself and walks through the job with you. Dust sheets go down in the room below and along the route in. Then the opening and upstand, or the flashing on a pitched roof, are checked against the unit's measurements. A loft roof window goes in, is fixed to the maker's pattern and sealed into the roof covering. Inside, the reveal is finished as quoted. Before leaving, the team clears debris and talks you through what was done. Most jobs of this type take one to two days.

Do you need permission in Thatcham?

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

For fit-only work, the product details matter most: the link, the spec sheet, or a photo of the label on the box. Alongside that, send pictures of the roof and the ceiling below, approximate opening sizes, the type of roof covering, and how someone would get onto the roof. For supply and fit, the same photos and sizes do the job. Finish with your postcode, such as RG19.

Common questions in Thatcham

How long does fitting take?

Fitting a loft roof window into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.

Can you fit the loft roof window 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 Thatcham?

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.
