Founded by architect, Peter King RIBA, the Rooflight Company created the original Conservation Rooflight® which today remains the best product in its class.

Spotting a gap in the market

When architect Peter King was practicing in London’s Hampstead Garden Suburb in the late 1980’s he had many clients who wanted to extend into their attics.

The problem was getting acess to light and ventilation – modern roof windows and dormers were completely out of the question due to the local Trust’s strict planning guidelines.

The only option was a cast iron single-glazed rooflight based on the Victorian design, which was prone to rusting and leaking.

Turning an idea into a business

Peter set about designing a copy of the Victorian cast iron model which would meet modern standards, using steel, double-glazing, draught stripping and a thermal lining.

He developed a range using sizes from original Victorian patterns and called it the Conservation Rooflight®. Conservation officers and architects loved it, appreciating its low-profile, glazing bar and slim sections, and have continued to specify it for over 20 years.

Now employing 70 people in Oxfordshire, all of whom are committed to designing, producing and providing the best products and services to our customers.

Design and Innovation is in our DNA

We are able to design and produce most sizes and shapes of rooflights with our Bespoke Design Service.

We are also able to offer any RAL colour for your roof windows.

And as a design-led company we’re always thinking of the next new development.


Working with architects and designers we introduced a new concept in roof window design – neo™.

Its edge-to-edge glazing and frameless appearance internally and externally offers a minimalist design aesthetic.
