With many of the Big Six energy suppliers announcing increases in their charges this winter, a fresh emphasis has been placed on the need for sustainability and efficiency to combat rising bills.

And in an attempt to ensure that those who live in the private rented sector aren't left behind, the National Landlords Association (NLA) has voiced its support for Big Energy Saving Week - a campaign spearheaded by the Energy Saving Trust and Citizens Advice.

The initiative is designed to encourage Britain's households to become more aware of their energy consumption, paying attention to the ways in which they can cut back on bills through making simple changes to their behaviour.

Whether it's ensuring that they only use the kettle to boil the amount of water they're going to need or turning the thermostat down a notch, there are plenty of easy ways for Brits to generate impressive savings.

But it's not only about remembering that it's not a great idea to leave the hot tap running, as there is renewable technology that can be installed to improve a household's green credentials and reduce its carbon footprint.

That's where landlords come in, as the NLA says that they should take steps to help tenants reduce their energy bills through making efficiency improvements in their properties.

"In light of the recent energy company price rises, many tenants are understandably concerned about their utility expenses," said David Salusbury, chair of the NLA.

"Landlords have a duty to ensure their properties are as energy efficient as possible, helping to minimise tenants' energy consumption."

From small additions such as LED lights to larger projects involving cavity wall insulation, there are many ways to boost a household's energy rating and cut back on bills.

And while the initial process will involve some sort of outlay, it should begin to pay off as a tenancy becomes more attractive, and landlord insurance policies can protect investors from any unexpected costs that they haven't budgeted for.
