What we do

Sava strives to make buildings better. We do this by providing education, technology, and compliance services to building owners, surveyors and the wider property industry. We were established in 1983, and our roots are within energy assessment and home condition surveying.

Sava is the new name of National Energy Services

On 1 February 2018, National Energy Services changed its name to Sava. The move to the new name Sava was part of the company’s strategy to communicate more clearly with its customers and to allow the business to grow and transform. The company’s registration details – such as its registered number at Companies House and its registered address –  remained unchanged.

Who we are

We are a team of building physicists and engineers, statisticians, software developers, residential surveyors, gas engineers and business management specialists.
