Wondering what it costs to have an EPC assessor to your home?
This EPC certificate cost guide breaks it all down for you including what the energy assessor does, EPC prices and more!
Let's begin!!
Are you looking for an EPC assessor but not sure about how much it will cost you?
The average cost of an EPC Assessor is normally around £15 to £25 per hour or £90 to £120 per day.
The cost of an EPC includes the survey conducted by a certified Domestic Energy Assessor as well as the Energy Performance Certificate. The Certificate rates the property's energy efficiency on a scale of A to G, with A indicating "Very Efficient" and G indicating "Not Very Efficient." In England and Wales, the average energy efficiency rating for a property is band D.
The EPC will also assign a rating to the property ranging from 1 to 100, with a higher number indicating greater energy efficiency. Fuel bills will be lower if your home is more energy-efficient. Therefore, getting an EPC assessor is the better option as they can improve your home, and they are only needed around every ten years, so you probably won't need another one.
To find out more about what EPC assessors do and how much they charge, take a look at the following guide, which will break down everything you need to know.
We will also go over the qualifications and insurance an EPC assessor needs. Therefore, if you are moving homes and want the process to be easy and find the perfect EPC assessor for an affordable price, then this article will help you on your journey of finding the perfect one.
An EPC is meant to provide information about a building's energy performance to potential purchasers or tenants so that they can consider energy efficiency as part of their investment or business decision to buy or occupy that property. An EPC assessor job does not affect the cost of the overall assessment. However, they can include different roles and what is expected from them.
In the United Kingdom, the average hourly rate for a domestic energy assessor is around £14 per hour.
The cost of an EPC will vary depending on the following factors:
For example, an EPC for a large house in London will likely cost far more than an EPC for a one-bedroom unit in Grimsby. Many individuals obtain an EPC from their estate agent because it is a convenient choice, but it may end up costing you more in the long run.
EPC assessors also vary their price depending on how many hours a day they work, as some jobs can take longer than others. Therefore, if your building is slightly different, the EPC assessor cost per hour might increase as the assessor is taking more time than usual to make sure it is perfect for you.
The table below sets out the average price of different areas in the UK:
Location | Cost Per Hour |
---|---|
North-west | £15-£20 |
North-east | £17-£20 |
South-west | £13-£17 |
South-east | £20-£25 |
EPC Assessor typically charges a daily rate of around £90. The daily rate varies based on where you live. The size of the property will also determine the cost; for example, a larger building will take longer to assess.
EPCs can cost up to £120, though most houses will cost far less if they are just an average-sized house with easy property. While all homes must have an EPC before being sold or rented, there is no value in going with the most expensive provider, so look around for the best bargain. It is often less expensive to hire a residential energy assessor directly rather than through an estate agent as they often give you more expensive options.
The below table sets out the daily rate for EPC assessors:
Location | Cost Per Day |
---|---|
North-west | £90-£100 |
North-east | £90-£95 |
South-west | £110-120 |
South-east | £110-£120 |
The below table provides a summary for the timeframes and EPC assessor costs for several jobs that require an Energy Performance Certificate.
EPCs are usually valid for 10 years, although for any significant changes to a property you may be required to apply for an updated review, especially as it is a legal requirement when selling or renting your property.
Renovation Type | Estimated Cost | Duration |
---|---|---|
Major Extensions | £45–£100 | 3–4 hours |
Loft Conversions | £30–£90 | 2–3.5 hours |
New Heating Systems | £30–£50 | 2 hours |
Cavity Wall Insulation | £22–£50 | 1.5–2 hours |
Garage Conversions | £30–£90 | 2–3.5 hours |
Whole-House Refurbs | £60–£150 | 4–6 hours |
If you have carried out any of the above jobs, then the chances are you may well need an EPC assessor to complete an official report.
Below are links to more information on the topics already mentioned, where you can find more detail on any costs you may encounter prior to applying for your EPC assessment:
If you are unsure as to whether or not any work you have had carried out requires an updated EPC it's best to contact your local council for advise or you could encounter additional costs further down the line.
To become an EPC (Energy Performance Certificate) assessor, individuals must hold a valid and recognised qualification aligned with the current National Occupational Standard for Energy Inspection.
These qualifications not only show the assessor is technically competent of doing the work, but may also cover specific types of buildings or system requirements. In the event they are called to a job outside of their accreditations, it is likely they will need to work alongside a more qualified assessor.
EPC assessors must also belong to a government-approved scheme to ensure they meet required standards. Only those who are suitably qualified can carry out the assessments, issue EPC certificates and have them officially registered.
If you are unsure when hiring a EPc assessor, then ask for evidence of their appropriate qualifications to carry out the job.
All qualified EPC assessors and clients must carry professional insurance and join a certified scheme for the safety and protection of energy assessors and clients. Both of which are faily common within the industry:
If you wish to double check, ask your assessor if they are fully covered prior to carrying out the review.
You'll need an Energy Performance Certificate whether you're selling a house, putting it up for rent, or even if you've built a house from the ground up (EPC). A professional Domestic Energy Assessor (DEA) issues this certificate, which establishes your home's energy efficiency rating. Before the property is put on the market, EPCs must be ordered.
The EPC assessor will need access to all rooms in the house, including the loft hatch, room in the roof, expansions, conservatory, and electric and gas metres (if applicable).
They'll make a rough sketch of the property's overall floor plan. After that, they'll go around each room, taking precise measurements and recording all pertinent information:
The EPC assessor will then calculate and produce your EPC Certificate after they have completed the survey. They will also take advice on how to increase the energy efficiency of your home.
The EPC certificate is then uploaded to the EPC Register, and you will receive an email copy of the report. On the EPC Register, you can always see a copy of your EPC certificate.
Commercial energy assessors evaluate commercial buildings' energy efficiency and provide Non-Domestic Energy Performance Certificates. Performing extensive inspections of properties and collecting information on the age, number of floors, and building type, as well as measuring the number and size of rooms and windows, would be part of the job.
The ability to detect heating systems is critical since it has a significant impact on the energy rating. They will then record the information on a computer system to generate an energy efficiency rating and an Energy Performance Certificate at the end of the day (EPC) working conditions. Commercial EPC assessors will also advise businesses on reducing energy usage and saving money in the long run.
A Non-Domestic Energy Assessor (NDEA) is a person who has been accredited by the government. Conducting an energy assessment, creating an EPC, and filing the EPC with their accreditation system are all tasks that energy assessors are accountable for.
Government-approved accreditation schemes ensure that energy assessors are qualified and have the necessary skills to conduct energy assessments, ensuring the quality of energy assessments and EPCs.
Energy assessors must be certified in the type of building being evaluated.
The different levels of an energy assessor include:
There are two ways to determine whether an energy assessor is a member of a certification scheme:
As a house settle,s cracks can appear in the floorboards or along the skirting boards, inviting an unwanted draught into the property.
Floorboards and skirting boards are typically addressed in the same manner; the gaps are located and then filled with a flexible material, such as silicone mastic or decorators caulk. This will stop the draught penetrating the home and, as it is flexible, allows for house movement without the risk of the seal being broken like you may expect with a brittle material.
When wanting an EPC, you can google ones near you. This will give you multiple options; however, how will you know which one to trust? Picking the right EPC assessor can be a task, as you want a reasonably priced, straight to the point assessor that will give you exactly what you want and need on your home.
Family/friend recommendations are often the best as they have had experience with the assessor, and you know that they will be good. Going online and looking for an EPC can be risky as they sometimes are not the best, and you don't know anything about them, so it is always a hit or miss.
However, to avoid this, it is best to research assessors or ask what type of insurance or work history they have done to make sure they are legit and won't waste your money.
A good EPC assessor will have:
Choosing the right energy assessor is critical for your EPC rating and the long-term success of your building management. It's not just about energy efficiency; it's also about the health of your company and its employees.
