Energy saving help for landlords

You can save money by improving the condition and energy efficiency of your properties.

Duty to improve energy performance

Private landlords must arrange an Energy Performance Certificate (EPC) on any property they intend to let. EPCs last for 10 years and should give any prospective tenant an idea of how much it will cost to heat the property.

From the 1st April 2018, private landlords must ensure that any property they intend to let out has an EPC rating of atleast band ‘E’.

From 1 April 2020, a private landlord will be in breach of the regulations if s/he continues to a let a property that has an EPC rating below band ‘E’.

A landlord who fails to comply could face a fine of up to £5,000.

EPCs include graphs showing the current and potential energy efficiency rating and environmental impact (CO2 rating) of the property.

Energy saving measures

These tips will help your tenants save money and help them to manage their energy bills.

Under £100

  • Swap inefficient bulbs for low energy bulbs and save around £55 a year
  • Fit draught excluders to windows and doors and save between £10- £50 a year
  • Seal and fill in gaps in the skirting boards and save £75 a year
  • A boiler jacket saves £30 a year

Over £100

  • Fill cavity walls with insulation in houses built after 1920. A semi-detached house will save around £145 a year.

  • Fit loft insulation (at least 270mm) and save up to £250 a year
  • Install solar panels and save up to £125 a year

Help your tenants cut their energy bills

Give your tenants a guide with suggestions on how they can save money on their energy bills, for example:

  • turn off appliances when not in use
  • turn down the thermostat by 1 degree Celsius and save around £60 a year
  • reduce washing machine cycle to 30 degrees Celsius
  • use a bowl to wash the dishes instead of leaving the hot tap running
  • keep shower heads clean.

The Green Deal

Before applying, you must get the tenants’ permission and acknowledge in the tenancy agreement that they will be paying the bills and repaying the Green Deal loan as part of the electricity bill for the property.

In particular, you must show tenants a copy of the EPC, which explains:

  • what improvements have been made
  • how much they have to repay
  • the length of the Green Deal Plan
  • the Green Deal provider

You are not liable if the tenant defaults. The electricity company uses their normal collection measures to collect money owed by the tenant.
