By [Jack Butler-Kettle]() · Updated 30 September 2026 Guidance for England and Wales. Check the contract, amendments and facts that apply to your job. ## What it means in practice Read this alongside [NRM 2: Detailed measurement for building works](). A schedule of rates provides prices for defined units of work. The descriptions, measurement rules and included allowances determine how a rate is used. A rate for one specification or working condition may not be appropriate for a materially different item. Retain the agreed descriptions as well as the numbers. [Variation recovery]() can help connect measured changes to the applicable valuation basis. ## Worked example ### The facts A schedule prices a defined type of painting at £12 per square metre. ### What happens 1. The subcontractor measures 50 square metres of matching instructed work. 2. It checks that preparation and access conditions fall within the rate's description. ### What this shows The illustrative £600 valuation follows only after confirming that the rate applies to the work measured. ## Sources 1.
