What does skylight installation in Hertford involve?
For Hertford homes and buildings we offer skylight installation: survey, supply and fit — new openings, extensions and fit-only work. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for skylight installation include new extensions, new openings and fit-only jobs.
Neighbouring towns include Hoddesdon (6 km) and Welwyn Garden City (9 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Hertford
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

The process, step by step
- Send the details. Postcode, rough size and a photo of the roof and room.
- Measure and check. A surveyor visits Hertford, measures and checks structure and access.
- Fixed quote. Product, work and price in writing — nothing is ordered until you agree.
- Fit and make good. We fit, seal, test and finish the reveal, then hand over the paperwork.

Common questions
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
Who handles building control?
We tell you which route applies — building control approval, a building warrant in Scotland, or in England and Wales self-certification by a registered competent person — and supply the product data.
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
Will I need planning permission in Hertford?
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 Hertford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
