On 20 May 2009, the National Measurement Office, which was then part of the Department for Innovation, Universities and Skills but is now an Executive Agency of BIS, published an Economic Impact Report-Metrology Investment: Impact on Innovation and Productivity. The models described in that report estimated that an additional investment of £6 million (10 per cent. of the annual investment at the time) in the National Measurement System (NMS) could enable additional GDP of between £300 million and £400 million through enhanced innovation.
The NMS budget covers work at several laboratories but about 80 per cent. of it is carried at the National Physical Laboratory. The National Physical Laboratory also carries out significant work not funded from the NMS budget.
