Skylight replacement for Plymouth: the essentials
Our skylight replacement service in Plymouth covers replacing tired domes and failed glass with a modern rooflight. 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. Skylight replacement suits older extensions due a modern rooflight.
We cover all of Plymouth and the PL1 district, and nearby Plymstock and Paignton.

Consents for skylight replacement in Plymouth
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. 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.

Skylight replacement in Plymouth: questions
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
