Skylight replacement for Southall: the essentials
Thinking about skylight replacement in Southall? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Think of skylight replacement for older extensions due a modern rooflight.
From Southall to Greenford, Ealing and Hayes, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Southall
- Roof window replacement in pitched roofs
- Dome to flat glass upgrade

Before you order: points to check
- A replacement is a chance to meet current thermal standards
- Enlarging the opening changes the structure and may need approval
Planning, building control and Southall
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.
