Flat rooflight installation in Orpington

Guide prices in Orpington

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.

Is your address covered?

Distance is rarely the deciding factor. A roof in Chislehurst, 3 miles from Orpington, gets the same survey, the same written quote and the same fitting process as one in BR6, BR5 and BR7. What changes the price is the job itself: size of unit, roof type, access and lifting. Swanley, around 4 miles out, is treated the same way.

What we check on a supplied unit

Which works out better, buying your own or letting us supply? It depends on what you value. Buying your own gives you control of the product and what you pay for it. Letting us supply puts the whole job, unit and fitting, under one written quote. On a customer-supplied unit we still measure it against the opening, look at the upstand, and inspect the condition it arrived in. Warranty on the product sits with whoever sold it, while the fitting carries our own guarantee.

Included in the work

• Fall confirmed so rain runs off the glass rather than sitting on it
• Lifting gear or extra hands arranged for large and heavy panes
• Reveal lined and trimmed inside, with the glass left clean
• Pitch of the glass — We make sure the glass will sit at the pitch its maker asks for.
• Solar gain on south-facing roofs — We ask which way the roof faces and how the room is used before suggesting glass.

A typical installation day

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 flat rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Regulations for Orpington properties

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.

Before you get in touch

Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, BR6 or nearby, confirms travel.
