Skylight installation for Guildford: the essentials
Thinking about skylight installation in Guildford? The short answer: survey, supply and fit — new openings, extensions and fit-only work. 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. Skylight installation suits new extensions, new openings and fit-only jobs.
We work across Surrey, including Guildford, and in neighbouring towns such as Godalming and Woking. Access, parking and how the glass reaches the roof are all checked at the survey.

Do you need permission in Guildford?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Is the survey free?
Yes, for new installations. Repair visits are charged.

Will I need planning permission in Guildford?
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.
