As the government continues to emphasise the importance of energy efficiency in UK homes, it appears that Britain's landlords are increasingly aware of the benefits of focusing on properties with strong carbon friendly credentials.

A survey conducted by the Association of Residential Letting Agents (ARLA) revealed that 61 per cent of investors do not own holdings rated 'F' or 'G' for energy efficiency - an 11 per cent jump on 2011, which reflects an emerging trend for landlords to prefer greener properties.

What's more, with a 12 per cent drop in the number of investors who do not know what bracket their assets fall into in terms of their Energy Performance Certificate (EPC) rating, it appears that landlords are paying greater attention to the energy efficiency of their portfolios.

"EPCs have attracted considerable scrutiny in the past, but it would appear that landlords are now paying increased attention to the efficiency of their properties," said Ian Potter, managing director of ARLA.

"This understanding is complimented by rising awareness of the 'split incentive' offered by the Government's Green Deal proposals [for the private rented sector].

"Increasingly, savvy tenants will ask to see a property's EPC or even ask about previous bills, therefore it is prudent for landlords to have a clear picture of the performance of their properties."

With prospective tenants more inclined to favour properties with a strong EPC rating as they look to combat rising energy prices, it seems that landlords can increase the appeal of their assets through making energy efficiency improvements.

And while the Green Deal will help them to combat the cost of installing green technology, there are other ways they can protect their financial position.

Landlord insurance policies will cover the cost of any damage to an investor's properties, safeguarding profits and reducing the risk of losses as they look to build a competitive portfolio.
