Skylight replacement for Boston: the essentials
Thinking about skylight replacement in Boston? 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.
Midlands housing is a mix of Victorian terraces, inter-war semis and newer estates, and rear kitchen extensions with flat rooflights are a common upgrade. Typical uses for skylight replacement include older extensions due a modern rooflight.
Boston sits about 23 km from Spalding and 31 km from Skegness, and we cover the whole PE21 postcode district and the roads in between.

Planning, building control and Boston
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. 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.
Read the planning permission guide before you commit to a design.

Skylight replacement in Boston: questions
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
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.
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.
Will I need planning permission in Boston?
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.
Is the survey in Boston free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
