Quantity surveying and cost consultancy

Getting the numbers right is fundamental to any commercial project. Whether you are funding a development, refurbishing an office, or building from the ground up, you need to know what a scheme will cost before you commit. A weak grip on cost can erode a scheme's return, expose a funder to unquantified risk, or leave a final account in dispute, so getting it right matters.

BTG Eddisons provides RICS-regulated quantity surveying services and cost consultancy trusted by developers, funders, investors, and occupiers across the UK. Led by chartered cost professionals and working to recognised industry standards, our cost consultants bring genuine method and independence to every instruction.

A quantity surveyor, also known as a cost consultant or commercial quantity surveyor, manages construction costs from first estimate to final account. The role is to give you independent, evidence-based advice on what a building will cost, to keep that cost under control once the contractor is on site, and to make sure the money you spend delivers the value you expected.

On commercial schemes, the stakes are financial. Capital is committed on the strength of a budget, funders release money against certified progress, and a poorly controlled contract can erode a return before the building is even finished.

Sound cost advice protects the budget, surfaces risk early, and gives everyone with money in the project a clear, defensible view of where it stands.

Quantity surveying fees are usually structured in one of three ways, and the right approach depends on the scheme:

• A fixed fee, agreed against a defined scope, gives you cost certainty on the advice itself.
• A percentage of construction cost scales the fee with the size of the project.
• A time-charged basis suits shorter, less defined, or advisory pieces of work.

We will decide which model fits your project and what is included before you appoint us, so there are no surprises. Fees are set on a project-by-project basis, and you can get a figure for your scheme by speaking to the team.
