Home Energy Audits

​​​​​​​​​​​​​About Home Energy Audits

A Home Energy Audit is a survey to tell you how energy efficient your home is. The more energy efficient your home, the more money you will save on your energy bills.

Having a Home Energy Audit done on your home tells you:

• how much energy you’re currently using
• recommendations of home improvements to make your home more energy efficient
• behaviours you can change to cut your energy bills, such as turning down your room thermostat by 1°C to save up to 10% on your heating bill

An Energy Performance Certificate (EPC) is awarded to a home as part of a Home Energy Audit.

Energy Performance Certificates (EPCs)

An EPC tells you how efficient your home is and gives it a rating from A (very efficient) to G (inefficient). 

Information about how your home is built and how it is heated is used to generate an EPC. It gives you a personalised list of home improvements that can increase your home’s EPC rating.

It also estimates how much energy your household currently uses, which shows how much energy you can save by making the suggestions provided.

EPC ratings give you a standardised way to compare your home with others.

EPCs can only be generated by a qualified assessor.

What a Home Energy Audit involves

A qualified assessor will visit you at your home to carry out an audit which takes between 45 minutes to 1 and a half hours. 

The assessor will need access to every room in your home so they can take measurements, photos and notes on how it’s built. They will ask you questions, such as whether you have your heating on a timer, and if so when it switches on and off.

After the visit the assessor will use the information they collected about your home to generate the EPC. They put the information into an online tool that has been personalised for Jersey homes.

The assessor will send you a copy of the EPC and run through the recommendations with you.

Cost of a Home Energy Audit

The cost of a Home Energy Audit varies depending on factors such as:

• age of your home
• size of your home
• if your home has had lots of extensions

It is likely to be in the region of £200 to £400. This is a guide only and we recommend you get at least 3 comparison quotes before you select your assessor.

Apply for funding for a Home Energy Audit

We are offering up to £150 funding per property towards a Home Energy Audit. Funding is dependent on the size of your home:

• £100 for 1 to 2 bedroom property
• £150 for 3 or more bedroom property

The subsidy amount available will gradually decrease until legislation for mandatory EPCs at point of sale or rental in 2026.  

You can apply for funding if:

• you own the property
  
• the property is older than 10 years old and does not hold a valid Energy Performance Certificate, obtained either through the property's initial building bye-law application or a previous home energy audit​
  

Funding is not available for Andium Homes properties.​

Apply for Home Energy Audit funding

Funding will be allocated on a first come first serve basis. 

You will be told within 5 working days of applying whether funding is available to you.

Your funding must be confirmed before your Home Energy Audit takes place, and must be carried out by a qualified assessor. We recommend you get at least 3 comparison quotes before you select your assessor, though you can get as many quotes as you wish.  

Funding will be valid for 8 weeks from the date issued. 

If the audit is not completed by the agreed date or any other terms and conditions are breached, the full cost of the audit is your responsibility.

You must email Energy Advice of you decide to not carry out a Home Energy Audit for whatever reason so that the subsidy can be reallocated.

Payment of Grants 

The value of the grant will be paid directly to the accredited assessor. The property owner will be responsible for paying the remainder of the cost directly to the assessor.  

The value of the grant will be paid once:

• the EPC has been lodged with Quidos
  
• the assessor has notificed Government of Jersey of the HEA reference number and corresponding EPC
  

The value of the grant will only be paid if the energy audit is carried out within the grant validity period.

Government funding of a maximum of £150 is available towards the cost of a ho​me energy audit. 

Assessors are responsible for collecting the full value of the Goods and Services Tax (GST) on this service. As it is a grant payment, GST should not be itemised on the invoice sent to government.

Property owners will need to pay GST as normal and will be responsible for paying anything over the grant amount.  

Landlords and multiple homes

Landlords that own more than one property may apply multiple times. Up to 10 subsidies can be claimed per person.

If you would like to apply for a Parish owned property email energy advice to find out more.
