This page provides general practical guidance and does not replace project-specific legal, engineering, planning, ecological, asbestos or waste advice.
The short answer
A useful first enquiry includes the site postcode, photographs of the structure and access route, what must be removed, what must remain, and any available plans or surveys. The more clearly the scope is defined at the outset, the more accurately it can be priced — and the less likely the written quotation is to carry qualifications or exclusions that cause problems later.
Why it matters
Demolition and strip-out pricing depends on what is being removed, what is being retained, how waste leaves the site and what condition is required at handover. Without that information, a contractor is pricing a generic scenario rather than the actual job. A quotation based on incomplete information is more likely to require revision once work starts.
Information that may be needed
Photographs, plans, structural drawings, asbestos information, service information and the required handover condition may all be relevant. For larger or more complex projects, a brief written scope of works is more useful than a verbal description.
What can affect the scope
Access, waste routes, retained structures, roof materials, service responsibilities and the condition required for the next contractor can all change the scope. Restricted access, manual carrying distances and building-management rules affect both method and cost.
When specialist input may be needed
A structural engineer, asbestos professional, ecologist, utility provider or local authority may need to be involved depending on the structure and proposed work. Identifying these dependencies early prevents them from becoming programme risks.
