How we approach dome rooflights in Henley-on-Thames
Our dome rooflights service in Henley-on-Thames covers polycarbonate and acrylic domes for flat roofs, new or replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Dome rooflights suit older flat roofs with yellowed or leaking domes.
From Henley-on-Thames to Reading, Earley and Maidenhead, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Clear, opal or tinted
- Fall-through protection mesh
- Twin, triple or quad skin
- Quick replacement on existing upstands
- Smoke-vent versions available
Things we check at survey
- Fire classification matters on some roofs
- Plastic domes have a lower acoustic and thermal performance than glass
Building control and safety duties in Henley-on-Thames
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. We confirm the route for your building before ordering.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fragile-roof safety and access are planned before work starts.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can domes open?
Hinged and vented domes are available, manual or electric.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Can you work alongside my builder in Henley-on-Thames?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do you fit dome rooflights in Henley-on-Thames?
Yes. We survey and fit dome rooflights in Henley-on-Thames and across Oxfordshire. Send your postcode and we will offer a survey date when we reply.
