A Scottish company is reporting a significant surge in work following a decision to restructure its business to target the Government's Green Deal campaign.

Firstcall Home Assist says it has booked more than 500 Green Deal assessments since February's launch of the scheme that allows homes or businesses to pay for energy-saving improvements, such as loft or cavity wall insulation, heating, draughtproofing, double glazing and renewable energy technologies, through savings on their fuel bills.

The spike in activity could boost turnover by up to £3 million this year and is already prompting an expansion into larger premises and immediate recruitment of 25 new staff, to take the total to 60, which will allow the Edinburgh-based company to service customers across Scotland.

Paul Greaves, managing director, said they spotted early an opportunity existed to grow the business rapidly by seizing on the changing profile of the energy efficiency market in the UK.

"We set out on a clear strategy a year ago to be at the forefront of the Green Deal revolution in Scotland," he said.

"We have invested more than £200,000 in training our existing surveyors and installers and we are currently recruiting additional staff to help with the demand."

He added: "We have also done considerable work to research and secure the best possible range of energy efficient appliances and materials, as well as finance options, to ensure the property owner or tenant is getting the optimum advice and access to measures."

Edward Davey, the Energy and Climate Change Secretary, has said he believes the Green Deal will empower SMEs to enter the growing energy efficiency market, providing key innovation and the creation of new jobs at local and national level.

Under the scheme, homeowners and businesses can obtain access to 45 potential energy efficiency measures aimed at reducing carbon emissions and saving energy.

There are no upfront costs and the scheme is not means-tested.

The Edinburgh company offers advice on Government grants and a range of payment options including a bespoke Barclays personal loan.

Firstcall Home Assist was initially set up to offer competitive home emergency assistance policies to homeowners.
