A residential Energy Performance Certificate (EPC) is valid for a period of 10 years, should you wish to use it to sell or rent your property. An EPC report since their birth back in 2008 are not only used for property transactions for other things such as claiming the feed-in tariff (FiT) for solar PV systems or claiming a subsidy on a new biomass boiler via the RHI.

An EPC is meant to be a representative score on the energy efficiency performance of a domestic property. The higher thef score, the more energy efficient it is, with the average in the UK being 60/100, which puts in Band D on the energy efficiency scale (A to G). EPC reports since 2008, have had periodic changes in how they are calculated, with big changes going through in 2012 and in 2014, so even if you didn’t do anything to a property in terms of improving it, the values given by the EPC may well now be different today than when they were commissioned a few years ago.

Why is the age of the EPC important?

The process of deriving the EPC score has also improved over time, with assessors now required to spend more time in the property and take extra diligence in deriving their finished output. Also, the customers have got more knowledgeable about the process of an EPC being produced and don’t generally stand for descriptive discrepancies on their final reports, whereas in the past certain assessors produced shoddy pieces of work.

To claim the Green Deal Home Improvement Fund (GDHIF) voucher from the Government to essentially get money off energy efficiency improvements like wall insulation, boilers and glazing improvements, the EPC needs to be at least 2 years old.

For Green Deal Finance or ECO subsidy claims many suppliers in the market are asking customers to have EPCs that may not be more than 6 months old. For ECO in most cases you won’t need to do anything as the company providing the funding for loft insulation, cavity wall insulation or a new boiler should provide this for free as part of the funded service.

You may think having to constantly have a new EPC is a bit excessive on the Government’s part and is probably a way round the 10 year rule indirectly (asking consumers to have a new one created); in reality many of these schemes have a valid point, given that so much in the EPC framework has been updated over time. If you as a householder update your boiler, have your cavity walls filled or swap out your lighting for LED, all those changes will cause the parameters of when your initial EPC was created to materially change. With these material changes coming through it makes sense to have a more accurate EPC report.

EPC for the FiT and RHI

For a renewable technology system subsidy claim, whether it is for the FiT or the RHI you will need to have an EPC undertaken. For solar PV claims under the FiT, you should be ok on the age of the EPC as long as the rating on is shown as band D or better. For biomass boilers, heat pumps and solar thermal systems you will have to have a full Green Deal Assessment, which means that you have to provide both the EPC and the Occupancy Assessment Reports. The Green Deal Reports only really came in January 2013, which means that it is very likely that you will have a new EPC done with that service. A Green Deal Report can be created with an existing EPC, but most assessors will recommend having a brand new one created for the full assessment.

The other reason, the RHI is more stringent is that the Government doesn’t want to be paying out the subsidy without the right amounts of insulation going into the property. Obviously with all this process you will have a much more accurate and relevant EPC.

Do I need to have my EPC redone?

The answer depends on what you are doing. If you are selling a property then you may want to have a new EPC done, just so as to provide the potential buyer with the best energy performance advice; but otherwise as long as it is within the 10 year period it should be absolutely fine. Obviously if the EPC is already under 24 months old, then we would suggest you sit tight unless you have made major alterations to the property. If you have just put in a new boiler with solid wall insulation, you may want to commission a brand new one, which will give a higher score to the property.

10 years since the first EPCs

If you had your EPC done in 2007 when they were first introduced, it will now need renewing. EPCs are only valid for a maximum of 10 years.

MEES: New EPC regulations for landlords

As of April 2018, any tenancies longer than 6 months being granted or renewed will hinge on whether the property has an EPC rating of ‘E’ or higher. Landlords are liable to pay a hefty fine if they do not adhere to the regulations. Read more here.
