Skylights and rooflights in Penzance
We survey, supply and fit skylights and rooflights in Penzance and the TR18 district — flat rooflights, roof lanterns, roof windows, walk-on glass, sun tunnels and commercial rooflights.
Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street.
Jobs in Penzance are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

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.
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.

Skylight questions: Penzance

Yes. We survey and fit skylights and rooflights in Penzance and across Cornwall. Send your postcode and we will offer a survey date when we reply.
Is the survey in Penzance free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Penzance?
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.
What guarantees do I get?
Products carry the manufacturer's own warranty, which we pass to you with the product data. Our workmanship terms are set out in the quote.
Will a rooflight make my room too hot?
It can on a south-facing roof with clear glass. Solar-control glass, an opening unit and a blind keep the room comfortable.
