Planning and building regulations for Washington
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations in Washington are checked by your local authority building control team or a registered building control approver. Replacing a rooflight in an existing home is building work. Installers registered with a competent person scheme can self-certify; otherwise building control must be involved.

Questions from Washington
Who deals with building control?
We will explain on your quote how building regulations will be met for your job and who is responsible for any notification.
Do you need to survey before fitting?
For a lantern on a ready upstand, clear photos and measurements are often enough. Replacements and new openings need a survey.
Is it worth having solar-control glass in Washington?
With the midsummer sun about 58.5° high at noon, roof glass in Washington gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Who checks building regulations for a lantern in Washington?
Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
