Data sources & credits

Listings in DoINeedAGlazier.com are compiled from the sources below. Each is named with the dataset it came from, the licence it is used under, and the credit that licence requires. Where a licence makes attribution a condition of use, that credit is reproduced here word for word.

  Companies House verbatim: "Material of this sort is subject to Crown copyright protection and is made available on GOV.UK under the Open Government Licence v3.0" and "if information is used from guidance notes, the website, publications or statistical tables the customer must credit Companies House as the source". OGL v3.0 verbatim: "acknowledge the source of the Information in your product or application by including or linking to any attribution statement specified by the Information Provider(s) and, where possible, provide a link to this licence" — and the condition is self-executing: "if you fail to comply with them the rights granted to you under this licence ... will end automatically". CH specifies no bespoke attribution statement of its own, so the OGL default line above applies (re-confirmed 2026-09-10 on the bulk-download page http://download.companieshouse.gov.uk/en_output.html, which carries NO licence statement at all). TENSION, named not resolved: the same CH page also says "Companies House imposes no rules or requirements on how the information on the public register is used." That sentence is about USE, not about the licence grant; it does not withdraw the OGL acknowledgement condition, and the safe reading (give the credit) is also the cheap one. Graded HIGH on the licence + line; the register-carve-out reading is recorded so a ruling can overturn it deliberately.
