Areas around Hanworth we cover
Hanworth and the districts around it, TW13, TW12 and TW2, all sit inside our working area. So does the ground between Hanworth and Hampton (2 miles), and on towards Feltham (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.
Buying your own, or letting us supply
Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a conservation rooflight on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.
On the day, we cover
- Slates or tiles made good around the frame with tidy cuts
- Inside lining fitted to suit the room's ceiling or exposed rafters
- Position checked against any consent drawings or council conditions
- Energy and old roofs — We make sure the rooflight meets current energy rules while suiting an older roof build-up.
- Glazing bar and frame detail — We check whether the council has asked for particular details, such as a central glazing bar or a dark frame colour.
From arrival to clean-up
On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a conservation rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.
Regulations for Hanworth properties
In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.
What to send for a quick 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 TW13.
Common questions in Hanworth
Can you fit the conservation rooflight 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.
What if my roof opening is the wrong size for the conservation 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 Hanworth?
Yes. Fitters travel to addresses in Hanworth and the surrounding districts, including TW13. 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.
Send a few photos and your TW13 postcode, and we will put together a written quote for the job.
