How to Improve EPC Rating: A Step-By-Step Guide

How to Improve EPC Rating: A Step-By-Step Guide

Saving energy helps protect the environment and saves you money.

To reduce energy usage and lower bills, start by checking the Energy Performance Certificate (EPC) rating, which rates how efficiently you use energy, from A (very efficient) to G (inefficient).

Most importantly, the EPC gives you a guide to improve your rating and save a significant amount of money on energy costs. Let’s look at the top recommendations and practical tips on how to improve EPC rating and make your property more energy efficient.

What is the EPC Rating?

The EPC rating is an initiative by the European Union to promote energy efficiency across member countries. An EPC provides two crucial pieces of information about a property: energy efficiency and environmental impact.

The EPC assigns a rating to a property’s energy efficiency from A to G, with A being the highest and most energy-efficient rating, and G being the lowest. This rating is displayed as a graph like those found on kitchen appliances. It allows homeowners and occupiers to compare the energy efficiency of different properties easily.

What is the EPC Rating?

The EPC rating scale is as follows:

  • Very energy efficient – lower running costs
    • (92 plus) => A
    • (81-91) => B
    • (69-80) => C
    • (55-68) => D
  • Not energy efficient – higher running costs
    • (39-54) => E
    • (21-38) => F
    • (1-20) => G

The EPC gives you potential improvements to cut fuel bills, improve energy efficiency, and help reduce carbon emissions on your property.

Why is It Important to Improve Your EPC Rating?

There are various benefits when energy efficiency and the EPC rating are improved. It is not just about lowering your energy bills, but it results in many other indirect profits. The following are the primary benefits of improving your EPC rating:

Save on energy bills

When you manage to upgrade inefficiency in your energy use, you will achieve substantial savings on energy bills. Well-insulated buildings can prevent heat from escaping, which requires less energy to maintain indoor temperatures.

Research findings from Citizens Advice show if 13 million homes are updated to EPC C, they could save £24 billion on consumers’ energy bills by 2030.

Ease the burden on energy networks

Citizens Advice has also shown that when national and peak electricity demand is reduced by 8%, it will significantly lower the strain on energy networks. As a result, it will decrease the cost of producing and distributing energy. Thus, there is less need for costly infrastructure upgrades and more improvements in grid stability and operations in the gas system.

Boost social benefits

Improving energy efficiency has far-reaching societal benefits. Based on the research of Citizens Advice, if 13 million homes that waste a lot of energy get better insulation, it could reduce the amount of harmful CO2 gas in the air in Great Britain by 33 million tonnes by 2030. That’s a huge 5% cut in emissions by that year. It would also lower air pollution and provide £2.7 billion in benefits to society.

On top of that, warmer homes can actually save lives. Up to 6,000 extra deaths in winter could be avoided every year if homes were better insulated. This would create social and economic benefits worth £6.6 billion.

Reduce strain on the NHS

Making homes more energy-efficient can positively impact people’s health. When homes are warmer, there are fewer cold-related illnesses.

If 13 million homes are more energy efficient and meet the EPC C rating, there could be up to 30% lower the number of patients with these illnesses during the coldest months. This could save the National Health Service (NHS) around £2 billion by 2030, according to Citizens Advice! As a result, it would mean shorter waiting times for patients to get the treatment.

Solar photovoltaic panels require a potential installation cost of £5,000–£8,000, which can save you typical yearly savings of £287 and enhance your EPC rating to a B-83 level.

3. Fit a More Efficient Boiler

If your boiler is old, you should switch to a new condensing model, which can reduce the energy volume used and improve your energy efficiency as a result.

With a potential installation cost of £2,200–£3,000, a more efficient boiler can bring a typical yearly savings of £339 and elevate your EPC rating to a C-74.

4. Modernize Electric Storage Heaters

Another effort you must make on how to improve EPC rating is high heat retention storage heaters and a dual immersion cylinder. It is estimated to give £319 annual savings with the initial installation being £1,200–£1,800. Moreover, this improvement can boost your EPC rating to a D – 67.

4. Modernize Electric Storage Heaters

5. Enhance Central Heating Controls (Programmers, TRVs, And Room Thermostats)

If you still use an older boiler, it is recommended to introduce modern controls like room thermostats, individual thermostatic radiator valves, or boiler programmers. These devices often require substantial initial expenses, but these upgrades are one of the easiest ways to improve your property’s energy efficiency.

6. Replace Or Remove Secondary Heating

Secondary heating sources are the main causes of inefficiency in energy usage, so it is best to replace or remove them. A new condensing model can significantly improve your EPC rating to a C – 74. Its installation cost is around £2,800 on average and it will bring the typical savings of £339 per year.
