Guide ranges for supply & fit; the electrician's final connection is quoted separately. 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.
Coverage in and around Guildford
Jobs across GU1, GU2 and GU4 are part of our normal cover for Guildford. 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 Godalming and Woking are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.
Your electric opening rooflights or ours
Your unit or ours, the fitting standard is the same. For supply and fit we choose an electric opening rooflight 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
- Cable route planned through the kerb or reveal before the lining goes on
- Wall switch, remote receiver or control box fixed in place
- Rain sensor positioned where it will get wet when rain starts
- Rain sensor position — We place the rain sensor where rain will reach it quickly and debris will not cover it.
- Where power comes from — We find a sensible power supply for the rooflight before fitting day.
A typical installation day
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 an electric opening rooflight: one day, plus the electrician's connection, weather permitting.
Planning, building control and Guildford
Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.
Details that speed up your quote
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 GU1 and we will come back with a quote or a survey date.
Common questions in Guildford
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.
How long does fitting take?
Fitting an electric opening rooflight 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.
Do you cover Guildford?
Yes. Fitters travel to addresses in Guildford and the surrounding districts, including GU1. 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.
