How we approach sun tunnels & tubular skylights in Didcot
For Didcot homes and buildings we offer sun tunnels & tubular skylights: light pipes that bring daylight to halls and bathrooms with no window. 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. Sun tunnels & tubular skylights suit windowless hallways, landings and bathrooms.
From Didcot to Abingdon, Wantage and Oxford, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Didcot
- Integrated electric light
- Insulated tube sections
- Diffusers in several sizes
- Rigid (brighter) or flexible tubes
- Pitched or flat-roof flashings
- Daylight where no window is possible
- Works on pitched and flat roofs
What to check first
- Tube runs need insulation in cold lofts to limit condensation
- Gives light, not a view
Planning, building control and Didcot
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.
