Guide to estimating the value of building work

The following table of fees is based on the Building Cost Information Service review of building prices for April 2026.

The cost of a building warrant  is based on the value of any proposed building work. The tables below contain the cost per square metre for a variety of different construction projects in the West Lothian area. These tables will be used by building standards to determine the estimated value of any building warrants submitted.

Once the estimated value of works has been calculated, the April 2026 Building warrant fee table (PDF, 74 KB)(opens new window) should be used to determine the building warrant fee. Payments should be made online.

Please note, when calculating the value of the works the tables below should be used as a guide, rather than any discounted costs which you might be able to achieve. For example, even if the labour was unpaid because it is a self-build project, the value of the building work should still include a fair assessment of the value of labour had commercial contractors undertaken the work.
