Roof lantern installation in Hertford

Guide prices

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?

Jobs across SG13, SG14 and SG12 are part of our normal cover for Hertford. 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 Ware and Hoddesdon are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

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.

What the job includes

• Caps, end closures and ridge trims fitted and sealed
• Glass lifted and laid into the frame by hand or with gear
• Roof membrane checked where it meets the lantern frame
• Upstand size and tolerance — We check the kerb against the lantern maker's figures before the kit is opened.
• Lanterns and planning — We check whether your lantern can go in without a planning application.

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 roof lantern 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 Hertford?

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

Keep it simple. Two or three photos, outside and inside. Approximate sizes. What the roof is made of. Anything awkward about getting up there, such as a conservatory below, a narrow side path or no parking. If you bought the rooflight online, the link or model name. Then your postcode in or around SG13. That is enough for a first price.
