Green Homes Grant


Three Rivers District Council has successfully secured Green Homes Grant Local Authority Delivery funding (separate from the former voucher scheme) to be administered by the Council to help local lower-income households improve their homes.

Three Rivers District Council are working alongside Watford Community Housing Trust, E.ON , and the National Energy Foundation to deliver grants to eligible residents. The Green Homes Grant scheme aims to help the country achieve its net-zero carbon goal, while also helping households save money, stay warm, and reduce their carbon footprint.

This scheme is targeting households who would like a warmer home but cannot afford to make energy-saving home improvements, with fully funded measures worth up to £10,000 for homeowners – or £5,000 contribution for landlords.  These energy efficiency measures may include wall, loft and underfloor insulation, solar photovoltaic panels, and low carbon heating upgrades, which will help to improve the warmth of your home and reduce your energy bills.  

Households in specific areas are being contacted by letter so we would urge you to consider if you qualify and then make contact with our partner on the number given in the letter.

If you have not been contacted by letter but think you may qualify, please contact the Green Homes Grant team at E.ON on their free helpline at 0333 202 4846, or email with your full name, address and phone number after which one of their advisors will give you a call.

Alternatively, you can apply for the scheme directly by completing a short online form on the E.ON website.


Note: The Green Homes Grant voucher scheme was withdrawn by the Government due to administrative issues on 31 March 2021. We will update this page if there are any further developments. 


About the Scheme

What is the difference between the Green Home Grant Voucher Scheme and the Green Homes Grant Local Authority Delivery Scheme?

The voucher scheme, which closed to new applications on 31 March 2021, was run directly by the Government and the Council was not involved in delivering it.

Our Local Authority Delivery scheme started May 2021 and finishes in March 2022, and is accepting applications. It is open to both homeowners and landlords, and is being administered directly by the Council who will refer you on to our delivery partner to manage and deliver the works to your property.

Only households living in properties with an EPC rating of D, E, F or G should apply. The household living in the property that will receive improvements must have a household income less than or in the region of £30,000 per year. Where a property is rented, that means that the tenants must have a household income less than or in the region of £30,000 per year. Large households and those with high housing costs may have incomes over £30,000 but could still be eligible so do call and check.

Do you have to pay back a Green Homes Grant?

No, you don't have to pay back a Green Homes Grant. The funding is provided by the Government to help the UK meet its zero-carbon targets.

Why We May Contact You

Why have you written to me?

We are writing to residents who we think might be eligible based on several different sources of information about local housing stock, including data on EPC ratings and the suitability of properties for different energy efficiency measures.

You do not have to take part if you receive a letter, but we are writing to you because we believe you may be eligible and could benefit from this funding.

Receiving a letter does not guarantee that you are eligible as eligibility is based on your specific household income and your property’s EPC rating. We do not know your household income, and your EPC rating could have changed since an assessment was last made.

If you have not been contacted by letter but think you may qualify, please contact the Green Homes Grant team at E.ON on their helpline at 0333 202 4846, or email with your full name, address and phone number after which one of their advisors will give you a call.

You can also apply to the scheme directly by completing a short online form on the E.ON website.


Check If You Can Apply

I am a tenant, how can I take part?

The scheme requires the permission of the homeowner or landlord. If you are a tenant, please tell your landlord about the scheme and ask them to get in touch with the National Energy Foundation to discuss whether they would like to take part.

I am a homeowner of a leasehold property; can I still apply to the scheme?

Yes, you can still apply. However, the type of measures you can have installed will depend on the terms of your lease agreement and we suggest you read through your lease agreement first. It may be that some measures can be installed (these are likely to be internal measures), but some others (likely to be external) will depend on whether your freeholder is willing to give consent.

If I have applied for the Government’s Green Homes Grant Voucher Scheme, can I apply for the Green Homes Grant Local Authority Delivery Scheme?

No. It is not possible to apply for both this scheme (the Local Authority Delivery Scheme) and the Government’s now expired Green Homes Grant Voucher Scheme. You cannot mix funding from the two, and you will be asked to declare when you apply to our scheme that you have not applied to the Voucher scheme.

If you have already applied for the Government’s Green Homes Grant Voucher Scheme and have progressed to the point where you have received quotes and successfully applied for the voucher, that voucher should be used and support from the Local Delivery Scheme cannot then be provided. If you have not yet reached this point, please do contact the National Energy Foundation to discuss your options.

How the Work Is Carried Out

Who carries out the work?

The works are managed by our main partner, E.ON. They will be your main point of contact throughout installation of the works and will arrange for a retrofit assessor to determine which measures are suitable for your property. They will appoint an accredited sub-contractor to undertake the work.  The quality accreditation scheme – PAS:2030 – will ensure the work is carried out to industry standards. Surveyors will sign off the project when the installation of measures is complete to ensure required standards have been met.

How disruptive will the works be?

This will depend on the nature of the work recommended. Some measures are quick to install and will not be very disruptive, others may require a deeper level of intervention. The nature of works will always be discussed in advance with the homeowner/landlord as part of the whole house plan.

Whilst there may be some disruption for a short period of time, the works should reduce the cost of your energy bills and make your home more comfortable in the long term.

How long will the works take?

The duration of the works will depend on the measures that your retrofit assessor determines could be suitable for the property. When producing a whole house plan, your retrofit assessor will explain the recommended works, the costs and the length of time these works could take.

What happens if COVID-19 restrictions affect works?

We will work with you and in line with Government guidance to carry out works safely.

Retrofit assessors and installers will follow Government guidance on working in other people’s homes at all times.

Financial Issues

How will you check my household income?

We will need to check your household income before you can receive funding from the scheme.

Household income is the combined gross income of all household members who are 18 years or older. Individuals do not have to be related to be considered members of the same household. Paying lodgers are not considered members of the household, although their rent payment will be considered as part of household income.

There are several documents we can use as evidence of income:

  • The last 3 months of bank statements for all bank accounts held. These must be consecutive.


and / or (if employed)

  • Five wage slips in a row if paid weekly or
  • Three wage slips in a row if paid every two weeks or
  • Two wage slips in a row if paid monthly
  • If you have recently started a new job, a letter from your employer confirming salary / a copy your contract of employment

If you are self-employed: accounts for the last financial year or a trading summary if you have only recently started trading

Once personal data has been checked, the information will not be retained.


If I have savings but am on a low income, can I still apply?

Yes. Eligibility for the Green Homes Grant LAD Scheme is based on an annual household income in the region of £30,000 or less. For this scheme, savings are not taken into consideration.

If I want to apply to the scheme and am not in receipt of benefits, what information will you require?

In order to comply with audit processes, we require the last three months’ worth of bank statements for all bank accounts you hold and of anyone else in the household and, if applicable, pay slips. These will need to be full statements with nothing crossed out. We do appreciate that this is personal information and can feel intrusive. Our privacy notice sets out how we will handle your data, and you are also welcome to speak to E.ON directly if you have any concerns.

If you are successful in applying to the scheme, your property could receive improvements worth up to £10,000. This funding is coming from the Government and we are required to carry out due diligence to ensure that only people that are eligible benefit from this funding and to minimise the risk of fraud. We take the privacy of this information seriously.

My household income was more than £30,000 earlier in the year but my circumstances have now changed. I have applied for benefits but am not yet in receipt of them. What do I do?

You should still meet the income eligibility for the scheme. However, we will require three months of Bank Statements to verify this change in circumstances and will need to discuss with you any other evidence you can provide that verifies this change in circumstances. Please do get in touch with our partner, E.ON, to discuss this further.

Your EPC Rating

What is an EPC rating?

EPC refers to an Energy Performance Certificate, which measures the energy efficiency of a property on a scale of A-G (with ‘A’ having the highest energy efficiency, and G having the worst energy efficiency). 

I do not know what my EPC rating is, how can I check?

If you do not know the EPC rating of your property, you can check this online.

If your property cannot be found on the website, it is likely your property does not have an EPC rating. This is common where a property has not been sold or let in recent years.

My home does not have an EPC rating. Can I take part?

If your home has not been let or sold recently, it may not have an EPC rating. The EPC rating for a property can also be out of date if changes have been made to the property since it was last assessed.

You may still be able to take part if your property does not have an EPC. Please contact our partner, E.ON. They can do a brief assessment from the information you provide to estimate whether your home is likely to be EPC D or below. If they believe the property is likely to be EPC D or below, your household income qualifies, and you are keen to progress, they will arrange for an EPC assessment to be made, the cost of which is covered by the Grant.

I have an EPC for my property but have had energy efficiency works done since it was issued.  A new EPC was not issued, and I do not know what it now is. Can I still apply?

Yes, you can still apply. On the application form there is a box for you to indicate any works that you have had done since the EPC was completed. E.ON will carry out modelling to asses if your home is still likely to be EPC D or below. If they believe the property is likely to be EPC D or below and your household income qualifies, you will be able to apply. So please contact E.ON to check.

Your Privacy

How are my details protected?

Please refer to our privacy notice in the first instance.

We will ask for your consent to share your information when you complete our application form. Information would be shared (with consent) with our partner organisation E.ON to arrange for a whole house assessment and plan, with their accredited installers to enable works to be carried out, and with the Department for Business, Energy and Industrial Strategy (BEIS) when they are evaluating the impact of the scheme.

Other Help

My landlord has said they do not wish to participate in the scheme. I am living in a cold property. What can I do?

Unfortunately, this scheme does require the permission of your landlord, and they would need to contribute a minimum of 1/3 of the total costs of the work. Therefore, if they decide they do not wish to participate, you will not be able to take part. If your landlord is undecided about the scheme, please encourage them to speak to E.ON on 0333 202 4846.

If your landlord does not wish to participate, you may qualify for alternative support. Please visit Home Energy Efficiency Grants ( for more information.

Please note that since 1 April 2020, landlords can no longer let or continue to let properties covered by the MEES Regulations if they have an EPC rating below E, unless they have a valid exemption in place. Read more information on the MEES regulations.

If you are a private tenant in a property covered by the MEES regulations and the EPC rating for your property is an F or a G, or if your privately rented property is rated E or above and you believe it is excessively cold, please contact our partner, E.ON at 0333 202 4846.

How will these home improvements lower my energy bills?

Measures funded by the Green Homes Grant will make your household more energy efficient. Insulation measures not only keep the heat in so you don't have to spend as much heating your home, but also help keep the cold out.

Low-carbon heating measures such as Air Source Heat Pumps and Solar PV both cost less to run that traditional methods, and Smart Thermostats put the power in your hands by allowing you to keep an eye on your heating and control it from mobile devices.


Information for Installers

I am an installer and would like to get involved in delivery of the scheme, how can I do so?

Please contact our main partner for the delivery of the scheme – E.ON. Please note that in line with the Government guidance for the scheme, all installers must be TrustMark registered. Contractors/installers need either MCS or PAS:2030 accreditation.
