But in its response to a two-month consultation, DECC said that while energy-efficient lighting can make significant savings in larger non-domestic buildings, ‘it has proved difficult to date to model standard energy-saving estimates for lighting systems and controls in domestic properties’.
DECC also said it was concerned that people might remove low-energy lamps when they move house, which would cause problems because Green Deal repayments are linked to properties rather than people.
Lighting has also been left out of the Energy Company Obligation, under which energy suppliers will have to subsidise energy-efficiency work for poorer households or those where savings are harder to achieve.
Green Deal support will be available, however, for lighting systems, fittings and controls at businesses and other non-domestic properties. The government said it will continue to work with the lighting industry to review what measures are and are not covered.
The decision comes as energy secretary Ed Davey sets out secondary legislation paving the way for the Green Deal to come into operation in October.
The system is to be run by a network of accredited providers, assessors and advisors, helping households and companies to pay for energy-efficiency measures from the savings they make on their electricity bills.
The idea is that repayments will not exceed the expected savings from energy-efficiency measures. Because repayments are linked to properties rather than individuals, any new occupant who moves in will have to take over repayments from the previous occupant.
The Confederation of British Industry said this week that the scheme has the potential to cut costs and generate business and jobs, but that “there is still plenty of work to do” to make sure it works for businesses and consumers.
Engineering body CIBSE’s certification arm is one of the organisations that will be able to certify companies that want to provide Green Deal services, as part of an oversight system that will be run by energy industry services firm Gemserv.
Twenty-two companies including British Gas, E.On and Anglian Home Improvements, signed an agreement with the government in April to become the first Green Deal providers. DECC is holding a series of briefings across the UK in June and July for manufacturers, installers, advisors and consultants who are interested in becoming part of the Green Deal supply chain.
