Loft conversion roof windows in St Albans

What the job costs in St Albans

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.

Fitting across St Albans and nearby

Jobs across AL1, AL2 and AL4 are part of our normal cover for St Albans. 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 Harpenden and Hatfield are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Already bought your unit?

There are two ways to do this. Supply and fit means we source a loft roof window that suits your roof and install it, so one company answers for both the product choice and the fitting. Fit-only means you buy the unit and we install it. With fit-only, the product warranty stays with the maker or seller, and our written guarantee covers the fitting work. Both routes get the same checks on the opening, the upstand and the maker's instructions before anything is fixed.

What we do on the day

• Window positions set out on the slope to line up inside and out
• Linings fitted, ready for the plasterboarder or decorator
• Underlay dressed and taped around every frame
• Balcony-style windows — We check the rafters and the roof pitch before recommending balcony-style windows.
• Approved loft drawings — We work to the window positions on your approved loft drawings or agree changes with your builder first.

How a fitting day runs

Where a job takes one to two days, the split is usually structural work first and finishing second. Early on, the fitters cut or prepare the opening, trim where needed and prepare the upstand or flashing. Then a loft roof window is lifted in, fixed and made weathertight so the roof is sound before anyone moves inside. Plasterboard, trim and filler for the reveal come after. Each evening the work area is swept, and at the end the glass is cleaned and the team talks you through what was done.

Regulations for St Albans 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.

Getting a price from photos

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 AL1. That is enough for a first price.
