Pitched roof windows for Berkhamsted: the essentials
Thinking about pitched roof windows in Berkhamsted? The short answer: centre-pivot and top-hung skylights for tiled and slate roofs. The longer answer depends on your roof, which is why we survey before we price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Pitched roof windows suit lofts, attic rooms, landings and vaulted ceilings.
From Berkhamsted to Chesham, Hemel Hempstead and Amersham, the same survey-first process applies: measure, specify, fix the price, then fit.

- Double or triple glazing

Planning and building rules for Berkhamsted
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about pitched roof windows in Berkhamsted
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
Do I need planning permission for a roof window?
Often not, under householder permitted development, provided it does not project too far above the roof plane and conditions are met. Listed buildings, flats and some conservation areas are different. Our planning guide covers each nation.
Will it need building regulations approval?
Fitting a new roof window usually involves cutting rafters and changing the thermal envelope, so building control approval (or, in England and Wales, a competent-person route) is normally needed. We tell you which applies.
How do I book a survey in Berkhamsted?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Berkhamsted?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
