Information and project-specific advice
The service descriptions and guidance explain the kinds of work we offer. They are general information, not a project-specific assessment, approval from Building Control or a substitute for reviewing the applicable requirements and project documents.
Building Regulations, Approved Documents and assessment methods change. The requirements applying to a particular project depend on its circumstances, location, dates and transitional provisions. Contact us to establish the appropriate assessment route.
Enquiries and appointments
Submitting a form, sending drawings or receiving an enquiry reference does not appoint us or authorise professional work. We will agree the assessment scope, deliverables, fee, programme and appointment terms separately before work begins.
A requested-by date in the form is a request, not a confirmed completion date. The quotation and appointment will explain the information we need, any assumptions and the treatment of revisions or additional work. Those agreed terms govern the commissioned service.
Information and files you supply
Please provide accurate information and tell us about relevant changes. Only upload files you are entitled to share for reviewing the enquiry and carrying out any subsequently agreed service. Do not upload malicious files or use the form to send unsolicited advertising.
You retain your rights in the files you supply. Submitting them allows us to use them for the enquiry and any agreed service, subject to the privacy policy and appointment terms.
Website content and external links
Please contact us before reproducing website text, images or branding. Some material belongs to third parties, and its appearance here does not grant permission to reuse it.
Links to external guidance are provided for convenience. External websites are operated by their respective providers and may change independently. Check the date and applicability of any guidance you intend to use.
Availability and your rights
We may update the website and its information. If a form or download is unavailable, please contact us by email or telephone. Nothing in these website terms removes rights that cannot lawfully be excluded or replaces the terms agreed for a professional appointment.
