Catch conservation and heritage work early
Heritage glazing gets specified in conservation areas and near listed buildings. Filter to those flags, or alert on sash or Crittall.
New-build blocks before the facade package
Major schemes specify glazing and curtain walling early. Read the brief and value band. Pro names the architect and developer.

Free to start. Pro is £39/mo, or £29/mo billed annually.
Free covers search, application views and one daily alert, with each firm shown by its Companies House number. Pro adds the firm names, the project team on major schemes, published contact details and competitor watch. Team shares one pipeline across up to 5 users.
Frequently asked
Which window replacements need a planning application?
Often none on a house outside a conservation area. Listed buildings, conservation areas with an Article 4 direction, flats and commercial buildings commonly do, and that is where specialist glazing gets specified.
Can I use EPC ratings to find glazing work?
Yes. An EPC filter is on every plan and picks out residential applications with a low rating on their own certificate, where better glazing is a common recommendation.
Can I filter to listed buildings and conservation areas?
Yes. SiteLens checks every mapped application against 24 planning designations, including conservation areas and nearby listed buildings, and you can filter on them, free.
