Rooflights for Watford homes and buildings
We survey, supply and fit skylights and rooflights in Watford and the WD17 district — flat rooflights, roof lanterns, roof windows, walk-on glass, sun tunnels and commercial rooflights.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement.
Watford is the main town we list in Hertfordshire; we also cover nearby Bushey and Rickmansworth.

Planning and building rules in England
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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Skylight questions: Watford
Do I need to be at home for the survey in Watford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Watford free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Watford?
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.
Can you work alongside my builder in Watford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Can a skylight be fitted into an existing flat roof?
Yes. We form the opening, trim joists, build an insulated upstand, re-waterproof and make good the ceiling.
Fixed or opening?
Opening units suit kitchens, bathrooms and bedrooms; fixed units are simpler and cheaper where the room already ventilates well.
