For landlord clients we operate an open-book policy on all costs. Materials, plant, labour, sub-contractor invoices and our own time are all visible to the client through the build. Monthly reports show committed cost, actual cost, and forecast outturn.

The result is a level of trust that closed-book contracting struggles to deliver. Disputes are rare because everyone is looking at the same numbers.

Open-book also makes year-end accounting and HMRC reporting much simpler — every cost is already categorised against the project.
