Despite the high demand for homes in the private rented sector, landlords still have a lot to do when it comes to marketing their properties and ensuring that the tenancies they offer are attractive to prospective tenants.

So with renewable energy becoming an increasingly important topic and investors having to consider the potential for the introduction of legal efficiency requirements in the future, it's a sensible idea to start thinking about how to make certain improvements now.

Indeed, with advertisements in commercial media having to carry details regarding a property's energy performance rating as of next year, green technology in rented homes could become a way of making a tenancy more appealing as tenants look to save money on their bills and minimise their carbon footprint.

Yet while the benefits of renewable measures such as LED lighting and heat pumps are well documented, the best ways to go about improving a property's green credentials are not always immediately clear.

But as Christian Engelke, technical director at Viessmann, advises, draft proofing and insulation could be the ideal place to start - especially with winter on the horizon.

"Home improvement is primarily driven through the insulation of the house - cavity wall, loft and floor insulation," he said.

"Draft proofing through better windows and improving the ventilation rate in the property are also very important measures. Once that's been done, then the homeowner should then look at improving their heating system."

Whether it's installing energy efficient boilers that can drive down bills or investing in insulation that reduces heat loss, landlords can make their properties more carbon friendly and enhance their appeal to prospective tenants.

And in order to protect their investments and avoid incurring unexpected costs, landlord insurance policies can serve as an effective financial safety net as investors guard against the risk of suffering losses.
