Minimum Energy Efficiency Standards

Almost two years ago the government introduced major changes intended to improve the energy efficiency of rented homes.  There are concerns that in some towns and cities, rental stock is typically older, which could mean that many homes occupied by tenants may not have energy saving features such as cavity wall insulation or double glazing. 

Indeed, it has been estimated that although less than 6% of privately-owned homes fall into the lowest two efficiency brackets, where a tenant occupies the home then this could be as high as 20%.

All properties must now have an energy have an energy efficiency rating of at least an E before a new tenancy can be granted, and next month there are even more important changes.

This is because the legislation will impact landlords with longer term tenants because from 1st April, all rented homes must have an energy efficiency rating of E and above.

What you need to do:

Firstly, if you don’t know, you should find out what the current Energy Performance rating for your property is – you can find out by visiting The service is operated on behalf of the Ministry of Housing, Communities & Local Government.

If the Energy Performance Certificate has expired

If your property doesn’t have a valid EPC, then you’ll need to have an energy assessor complete an energy performance survey on your behalf. Their report will include the current energy assessment rating which could be anywhere between A and G. 

The report will include suggestions for how you could raise the property’s energy efficiency rating.

If the EPC is valid, but with an F or G

If your property has an F or a G rating then you need to improve its energy efficiency – see tips below.

How to improve the energy efficiency rating of your property

The range of improvements you can make varies from draught proofing, improved insulation, heating controls, and lighting – right through to installing certain renewable technologies. 

One of the least disruptive ways to improve the energy efficiency rating is to switch to a low energy lighting. Meanwhile installing draught excluders and sealing up any gaps around loft hatches, doors and pipes could prevent heat from escaping – which would also cause relatively little disruption. 

Options such as installing a condensing boiler can give your rating a boost as much as 45 points – however this of course comes with a much higher bill.


If the only improvements which can be made to bring the property up to an E rating are not classed as ‘cost neutral’ then a five-year exemption can be granted. ‘Cost neutral’ is as defined by the ‘Green Deal’s Golden Rule’ – which is that the cost of the improvement is less than the estimated amount of cost savings it would generate over five years.  Whatever the efficiency status and rating of your let property, haart can help.  We work with energy efficiency practitioners across the UK who can assess your property and make recommendations for how to improve the energy efficiency.
