Skylight replacement for Liverpool: the essentials
Our skylight replacement service in Liverpool 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.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Think of skylight replacement for yellowed domes, misted glass and leaking roof windows.
We cover all of Liverpool and the L1 district, and nearby Birkenhead and Wallasey.

Do you need permission in Liverpool?
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. 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.

Common questions
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Do I need building regulations approval to replace a rooflight?
Replacements in existing homes generally need to meet current thermal standards and may need notification or approval. We advise on the route for your job.
Is the survey in Liverpool free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Liverpool?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
