Ensuring your rental property meets the EPC standards

If you’ve have property to let, you should be aware that changes to Energy Performance Rating standards are due to come into force from 1st April 2018. It’s also April Fool’s Day, of course, so to ensure that you don’t end up playing the fool next year, check that your rental properties are EPC compliant – or risk penalties, rent reviews and negative valuation.

EPC legislation changes at a glance

Under the new rules, all new lettings and renewed lettings must have an EPC rating of at least E. If the property doesn’t meet this requirement, it will be against the law to put it on the market or continue the existing tenancy unless improvements are made.

What changes can be made to improve an EPC rating?

If you have a property to let which is currently languishing in the F or G categories, you’re going to need to make some improvements before April 2018. You can help your property to become Energy Performance Rating compliant in the following ways:


Loft insulation should be at least 270mm deep in order to provide effective protection during the winter. Funding may even be available to top-up or fill lofts with current insulation of 90mm or less.

Cavity walls

If your rental property has cavity walls, filling these can help immensely with EPC ratings.


Properties with lighting which doesn’t meet LEL (Low Energy Lighting) guidelines should be replaced with more efficient Compact Fluorescent Lighting (CFL) or LED lighting. This inexpensive measure is incredibly effective, and should be the first port-of-call for anyone upgrading an older property.

Central heating

Replacing a central heating system is perhaps the trickiest and most expensive means of ensuring that your rental property meets EPC regulations. Older boilers are much less efficient than their newer, state-of-the-art energy saving counterparts. An ageing unit can have a significant impact on the EPC rating of a property and should be replaced if feasible.

Heating controllers

Modern heating controls like individual room thermostats, radiator valves and boiler programming systems all have a positive bearing on EPC results. These are easy enough for a qualified engineer to install but can be expensive to introduce.

Are there any exemptions to the new EPC rules?

Certain buildings may be exempt via a secondary piece of legislation – for example, listed buildings where renovations would be impractical or out of keeping with the style of the property would be excluded. Some short lease tenancies (less than six months) may also be exempt.
