Guide ranges for labour only, ex VAT for trade accounts. 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.
Where our fitters travel
Fitters travel to the job, so the address is what counts. In Chesham that means postcode districts HP5, HP6 and HP7, and the same teams can just as easily take on work in Amersham, about 2 miles away, or Berkhamsted at roughly 4 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.
What the job includes
- A short note of anything we found that needs your attention
- Roof lanterns assembled and glazed on your upstand
- Pitched roof windows fitted with their flashing kits
- Upstand ready and to size — We ask for the upstands to be built to the maker's drawing before we arrive.
- Building control sign-off — We agree with you how building control is handled before fitting.
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 rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.
Planning, building control and Chesham
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 agree up front who notifies it. 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.
Getting a price from photos
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 HP5 and we will come back with a quote or a survey date.
Common questions in Chesham
What is included in the price?
The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.
What upstand height and roof pitch does rooflight fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
Do you need scaffolding to fit a rooflight?
Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.
