All About Your EPC Rating – Part 1

All About Your EPC Rating – Part 1

What is an EPC rating?

An EPC is a document which states exactly how energy efficient your home is. EPC stands for ‘Energy Performance Certificate’. It takes into consideration various aspects of your home and judges how efficient they are. Your property will be given an overall rating between A – G. Your EPC certificate will also include areas to improve in the most cost-effective way and the potential rating that your property could be.

You may be thinking ‘’why are EPC ratings becoming such a topic of conversation lately’’ and more importantly ‘’why does it matter if my property has a G rated EPC rating?’’ Well aside from costings, which we will get into later, the main issue here lies with landlords and people who rent out their properties. As stated on the government website – ‘’Properties can be rented if they have an energy rating from A to E. If the property is rated F or G, it cannot be let, unless an exemption has been registered.’’ And it is very likely that an exemption will be accepted.

How can I find out what my EPC rating is?

All you need to do is go onto the government website or click on the link below and type in your address. From here it will show you a full breakdown on your property for free.

What’s included in my EPC rating?

When you look at your EPC certificate, you’ll see along the left-hand side the contents of what is included.

Rules on letting this property

This is the part of your EPC certificate which will tell you if you are able to rent or let your property based on the EPC rating.

Energy performance rating for this property

This will show you the energy rating of your property on a coloured scale as well as the potential rating on the same scale. Our example that we’re looking at is rated at a C with a potential rating of a B.

Breakdown of property’s energy performance

The next section is the breakdown of the property’s energy performance. This is the part where they go over how they got to the above rating. In the table it will show the wall insulation, roof insulation, window quality, heating and controls, water heating, lighting, floor insulation and secondary heating is all assessed and rated on either very good, good, average, poor or very poor.

Environmental impact of this property

This will tell you how many tonnes of CO2 your property produces per year, what the average household produces and the potential production for this property. This section also has a disclaimer that if you make the recommended changes, you could reduce emissions by x amount per year.

How to improve this property’s energy performance

Here shows the assessors comments on how you can improve your overall rating.

On the example that we used, our potential rating is a B. But how can we achieve this?

The assessor’s advice includes getting floor installation. It then shows the typically installation costs, in this case it’s £4,000 – £6,000 with a typical yearly saving of £39. Then it will show what your rating will be after making these changes.

Another recommendation is to get solar water heating, again with typically installation costs of £4,000 – £6,000 and a typical yearly saving of £36.

Estimated energy use and potential savings

Next on the certificate you can see the estimated yearly energy costs for the property. As an example, ours states £686, with a potential saving of £110 if the property owner follows the above advice. Most certificates will also have a disclaimer stating ‘’The estimated cost shows how much the average household would spend in this property for heating, lighting and hot water. It is not based on how energy is used by the people living at the property.

The estimated saving is based on making all of the recommendations in how to improve this property’s energy performance.’’

The next part under this section discusses heating. Again, with a disclaimer saying ‘’Heating a property usually makes up the majority of energy costs.’’

This part shows how much energy is used per year to heat this property and the amount of energy used for hot water as well.

Contacting the assessor and accreditation scheme

Lastly, the certificates show you who the assessor is and their contact details in case you have any issues, comments or queries about your EPC certificate.

I’m not a landlord or renting my property out, why is it important for me to have a low EPC rating? 

A low EPC rating can mean a number of things, but overall, it means higher costs. For example a low EPC rating will likely be related to poor insulation levels, low window quality, high energy lighting/water/heating and so on. If this is the case, it’s going to be difficult to heat. The heat won’t be retained well in rooms meaning they need to be on for longer and at a higher temperature. This means your overall running costs are going to be higher. With lighting, if using inefficient bulbs, it means lighting your property will be expensive compared to what it could be if you were to use efficient bulbs. Again with water, if you’re using a system that uses up a lot of energy, it’s going to cost you more money.

Even down to making small changes like the light bulbs, this should help with your EPC rating and in turn your bills!

Another point to make is, if you ever plan on selling your property, it doesn’t look the most attractive to a potential buyer if you have an E rating. They may see this and think that energy bills will be higher than normal and potentially a lot of work/time/money is going to be needed to put into the property to lower this.
