It is a legal requirement to have an EPC (Energy Performance Certificate) in place before marketing a property for sale or rent, however some people see them as a waste of time as buyers and renters seldom look at them.

I actually think EPC’s can be of more use than many believe though.

I was contacted recently by a first-time landlord seeking a rental valuation on the one bedroom flat he was in the process of purchasing. Seeing it was Grade II listed, without double glazing or gas central heating, my first port of call was to look at the EPC.

You can look up EPC’s on the EPC register ( free of charge. The property will be given an energy efficiency rating from A (highest) to G (lowest). EPC’s are valid for 10 years; so check whether your property already has one before an agent tries to sell you a new one.

I discovered that this particular property had an ‘F’ rating. This low rating combined with the flat’s Grade II listing, which would make improvements both difficult and costly, would pose a fundamental problem to the landlord…

From 1st April 2018 you will not be able to let out any property with an energy rating lower than an E!

Considering the F rated flat had been recommended to the investor as a buy-to-let by the estate agent, you’d have thought the first thing they might consider is “will he be able to let it in a few years’ time?”

In fact, almost 10% of the 4.2 million privately rented properties in England and Wales will not be lettable from April 2018 without improvements.

This particular landlord did some further research and decided against buying that particular flat, thanking me for my timely intervention and advice.

Another positive use for the EPC is that it identifies the measures that can be taken to improve the property, the cost of doing so and the potential energy savings they would bring.

When you combine this with knowledge of the available local and national government grants to improve energy efficiency in homes, you might find that you can improve the comfort and value of your property at a subsidised cost!

Whilst common sense should enable someone to look at the age of a property’s boiler, the state of its (double?) glazing and its heating type, the EPC will also set out the property’s likely electricity and gas usage and their cost.

Tenants and homeowners should make use of this, as it may be cheaper overall to rent or pay the mortgage on a modern energy efficient home at £950pcm rather than a poorly rated one at £900pcm.

If you’re in the process of purchasing a buy-to-let property and would like me to check its long-term viability, please get in touch.

  1. I disagree – to some extent.
    I\’ve looked at EPCs, and the way they are produced. To say I am not as confident as the article author in the \”quality\” of the information and advice in the EPC would be an understatement ! Stories abound of EPCs done where the person has not even set foot in the property, and without having taken into account important aspects – such as making assumptions as to whether there is cavity wall insulation !

    It is certainly worth reading the full report – the chart alone is more or less worthless without seeing the assumptions made in getting to it.

    • Simon, I certainly agree with you that many EPC\’s are fundamentally flawed due to the assessor\’s poor assumptions. Whilst I never claimed they were a \”quality\” source of information, I believe they are useful as the banding is the banding in the eyes of the law…..much like a Volkswagen\’s CO emissions for road tax banding purposes…..

      Some landlords may be in for a nasty surprise come 2018 and new investors should bear it in mind when purchasing a property.

  2. Another reason one may consider them a waste of time, is that they are (currently) valid for 10 years, yet the pace of eco-efficiency develops year on year.

    We purchased our flat under 2 years ago and it had a rating of 66. Although the smaller measures were taken (ie, not spending £10k on a boiler to save £100 per year) we installed the thickest possible loft insulation, replaced the old radiators with new efficient A rated, made measures to draft proof all the single glazed sash windows, and replaced every light bulb with LED / energy efficient light bulbs at great cost so thought it would be worthwhile spending a few more quid to receive a new EPC when putting it on the market.

    Despite the measures put in place, the new EPC came back at 61, because the EPC benchmarks have moved on during that period. Needless to say, we kept the 2 year old EPC and went to market.
