How we approach sun tunnels & tubular skylights in St Helens
Sun tunnels & tubular skylights in St Helens means light pipes that bring daylight to halls and bathrooms with no window. We cover the WA10 district and the rest of Merseyside, with a survey before any price is fixed.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. In St Helens, as anywhere, sun tunnels & tubular skylights are the usual choice for windowless hallways, landings and bathrooms.
Jobs in St Helens 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, building control and St Helens
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. 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.
Read the planning permission guide before you commit to a design.

Sun tunnels & tubular skylights in St Helens: questions
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
How much light does a sun tunnel give?
A good rigid tunnel on a bright day lights a hallway well. Output depends on tube diameter, length and the number of bends.
Do sun tunnels need planning permission?
Usually not on a house, provided the dome does not project too far and the property is not listed. Check if you live in a conservation area or a flat.
Can you work alongside my builder in St Helens?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in St Helens?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
