Sun tunnels & tubular skylights for Plymouth: the essentials
Our sun tunnels & tubular skylights service in Plymouth covers light pipes that bring daylight to halls and bathrooms with no window. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. Typical uses for sun tunnels & tubular skylights include windowless hallways, landings and bathrooms.
We cover all of Plymouth and the PL1 district, and nearby Plymstock and Paignton.

Planning, building control and Plymouth
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. 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.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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 it work at night?
Some models include a light fitting in the diffuser.
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
Do I need to be at home for the survey in Plymouth?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Plymouth?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
