Who can install green measures for you?

Only organisations that have registered with the Department of Energy and Climate Change, and have been authorised and given a Green Deal Quality Mark, can become Green Deal assessors, providers or installers. 

Assessors carry out the Green Deal assessment. They will send an adviser to assess your property and recommend which measures to install. Green Deal Providers are able to offer Green Deal loans, and can help you arrange installation of measures through a certified installer. Green Deal installers are traders authorised to install energy efficient measures in your home.

There are more than 500 organisations registered as Green Deal assessors and providers so far, and there are many more Green Deal installers. Authorised traders include: British Gas, Kingfisher, Npower, Scottish Power, SSE, The Big Green Energy Company and Wolseley UK. 

You can find your nearest registered Green Deal assessor, provider or installer by using the DECC search function

Just over a quarter of Green Deal providers offer Green Deal Finance.

Not all Green Deal providers are profit-making businesses. Besides shops, small companies and energy suppliers, local councils and social housing providers may decide to provide Green Deals themselves or partner with Green Deals provided by others.
