External Wall Insulation manufacturer Wetherby Building Systems has revealed that its 2012 turnover has risen to £61 million from £18.4m (2011).

The latest figures come on the back of three subsequent years of steady growth, with the company’s annual turnover now six times the £9.3m it achieved in 2009.

The increase in sales is attributed to the company’s involvement in governmental energy efficiency schemes CESP and CERT, since EWI solutions are one of the primary energy-saving measures included under the schemes, creating huge demand for effective EWI systems.

Wetherby is also seeing demand for its systems to be installed under ECO, the government’s latest energy efficiency scheme launched at the beginning of the year. Involved in some of the largest ECO schemes in the country, Wetherby has recently been selected to provide EWI solutions for a £20m project to renovate 4,700 homes for Watford Community Housing Trust, which is currently the largest ECO project in the UK.

Wetherby has also secured new supply chain deals with major energy companies and building contractors that have ECO contracts agreed, increasing demand for the company’s EWI systems.
