Coverage in and around Isleworth
Isleworth and the districts around it, TW7, TW3 and TW5, all sit inside our working area. So does the ground between Isleworth and Hounslow (1 mile), and on towards Heston (2 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

What happens on the day
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 rooflight 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.
Do you need permission in Isleworth?
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 on replacements we agree up front who notifies building control.
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 TW7 and we will come back with a quote or a survey date.
Common questions in Isleworth
Who deals with building control on trade jobs?
On new-build and extension work the rooflights usually sit within your approval or warrant. On replacements in homes in England and Wales we agree up front who notifies building control; we are not registered with a competent person scheme, so we cannot self-certify.
What if my roof opening is the wrong size for the rooflight?
We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.
Do you cover Isleworth?
Yes. Fitters travel to addresses in Isleworth and the surrounding districts, including TW7. 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.
