Inside this guide

  1. Read the benchmark as a dated starting point
  2. Define exactly which square metres are being counted
  3. Describe the room rather than relying on a shell label

  5. Keep approvals and VAT visible beside the build figure
  6. Reconcile the whole quotation before choosing a rate
