Energy advice for landlords and tenants

Affordable Warmth Network

We are part of the Buckinghamshire Affordable Warmth Network. Together with our partner local authorities, the NHS and National Energy Foundation the Network offers advice and funding to improve the energy efficiency of your home and reduce heating bills.

Free and impartial energy efficiency advice

Whether you rent or own your home you can call the Affordable Warmth Helpline (external website) on 0800 107 0044 between 9am and 5pm Monday to Friday, for free, impartial and expert advice on:

  • reducing your energy bills
  • heating your home economically and efficiently
  • grants and financial assistance
  • a free talk to your group

Insulating your home will help it stay warmer in the winter and cooler in the summer. It can be inexpensive and you may be eligible for assistance.

Energy performance certificates (EPCs)

Landlords are required by law to provide an energy performance certificate when they rent out a home. An energy performance certificate gives information on the energy efficiency of a property you want to rent.

Minimum Energy Efficiency standards

From April 2018, landlords of privately rented property must ensure that their property reach at least an energy performance certificate (EPC) rating of E before granting a new tenancy to new or existing tenants. These requirements will then apply to all private rented properties in England and Wales – even where there has been no change in tenancy arrangements – from 1 April 2020 for domestic properties, and from 1 April 2023 for non-domestic properties.

In addition to minimum energy efficiency standards, a landlord cannot unreasonably refuse consent to a tenant’s written request for energy efficiency improvements to their home where these can installed at no cost to the landlord.


Exemptions may apply in the following circumstances, where -

  • all relevant energy efficiency improvements have been made and the property remains sub-standard
  • a recommended measure is not a relevant energy efficiency improvement because it cannot be purchased and installed at no cost to the landlord
  • installation of wall insulation is not a relevant energy efficiency improvement due written expert advice confirming that the measure is not appropriate for the property
  • third party consent is required and despite making reasonable efforts this cannot be obtained
  • an RICS registered surveyor has confirmed that the installation may have a significant impact on the value of a property

There are limited circumstances for which a temporary exemption may also apply where you have recently become a landlord, a temporary exemption will last for six months from the date you become a landlord.

If you consider than an exemption applies which allows you to continue to let a property below the minimum energy efficiency standard, you must register this on the PRS Exemptions Register.
