Most landlords are considering having energy-efficiency measures installed in their properties, according to a survey by the National Landlords Association.

According to the NLA's latest Landlord Panel, 63% of landlords are aware of the Green Deal when it officially launches next month, and 56% are considering taking advantage of the initiative.

The Green Deal is the Government’s vehicle to make properties more energy efficient. To help encourage take up of the scheme, after 2018 any rental properties found to have a poor Energy Performance Rating (F or G rated) will no longer be fit to let.

Under the Green Deal, the cost of energy-efficiency improvements such as loft and wall insulation will be paid through a loan attached to the property’s energy bills. However, due to the energy savings achieved by the improvements, the energy bill will never be higher than it would have been if the work had not been carried out.

David Salusbury, Chairman of the NLA, said: "While our research shows that many landlords are keen to take advantage of the Green Deal, a third of landlords are not yet aware of the initiative. We encourage landlords to become familiar with the Green Deal as the private-rented sector has a key role to play in ensuring Britain meets its energy targets.

“Furthermore, it is imperative that landlords future-proof their properties and their investments. The Green Deal is their opportunity to improve the quality of their properties and demonstrate their ability to engage with government initiatives without the burden of further regulation. If landlords don’t act now, they may find their property cannot be legally let come 2018.”

The NLA Landlords Panel was conducted through 546 online interviews with NLA members, carried out in June 2012.
