How to improve the EPC rating of your rental property

Green homes grant for landlords

As a landlord, you’ll know only too well that currently, all rental properties must have a minimum energy performance certificate (EPC) rating of E, although there is the potential for this to change to a D or even a C in the next few years. With that in mind, now could be the perfect time to upgrade the energy efficiency of your property, to futureproof yourself (and the property) against any potential regulation changes.

Whether you decide to replace the boiler, fit new doors and windows or install an external wall insulation system, every measure will likely contribute to the overall EPC rating of the property. So which is the best option?

Choosing the right upgrades

Every property is different and will require a tailored solution to improve the EPC rating. For example, properties with poorly insulated loft space will benefit from additional loft insulation, improving both the EPC rating and making the property more comfortable to live in. 

Adding cavity wall insulation is a great option, however some properties – often older ones – will have solid walls and therefore need to find an alternative to mitigate heat loss through walls. Solid wall insulation can be added to a property in the form of internal or external wall insulation.

Why external wall insulation?

With around 33% of heat lost through uninsulated solid walls, an external wall insulation system is a great way of reducing the carbon footprint of your property without compromising on interior space, and gives you a chance to update the exterior too. We’ve got colours and textures to suit everyone’s taste – we’ve even got brick finishes for the traditionalists among you.

What’s more, with all the work taking place outside, there’ll be no need for your tenants to vacate the property whilst the renovations are carried out. This means no loss of rental income for you, and less hassle for your tenants.

Once the renovations are complete you and your tenants will experience benefits such as a refreshed exterior, a more comfortable interior, and lower energy costs. This will make the property more attractive to potential renters, as well as increasing the value in the long run.
