Green Homes Grant Voucher Scheme

These are the most frequently asked questions about the Green Homes Grant Voucher Scheme

  1. The Green Homes Grant Voucher Scheme is a government scheme that provides finance to homeowners to help them pay for measures that will help improve the energy efficiency of their homes. It is part of a series of measures to address climate change, and to create new jobs in the "Green Economy"
  2. The standard voucher is worth £2 for every £1 the homeowner spends on eligible energy efficiency measures under the scheme, up to a maximum value of £5,000 per household.
    For homeowners on certain benefits there is a low income voucher that is worth up to £10,000 and that does not require and contribution from the homeowner.

    For the standard voucher
    if you want to install measures worth £6,000 you will have to pay £2,000 to the installer and the voucher will cover the remaining £4,000.
    If you want to install measures worth £7,500 you will have to pay £2,500 to the installer and the voucher will cover the remaining £5,000.
    If you want to install measures worth £9,000 the voucher will still only cover the maximum £5,000, so you will have to pay £ 4,000

    For the Low Income Voucher
    if you want to install measures worth up to £10,000 you will not have to pay anything and the voucher will cover the whhole amount
    if you want to install measures worth £11,000 the voucher will still only cover £10,000 and you will have to pay the remaining £1,000.
  3. Vouchers are valid for 3 months from the date of issue.

    However, the Green Homes Grant Scheme will end on the 31st of March 2022 so all vouchers applied for after 31st December 2021 will expire at the end of March regardless of when they are issued.

    All work under the Green Homes Grant Scheme must be completed within the validity period of the voucher, However as there is a 10 day process between the voucher being submitted by the homeowner and the scheme paying out, installers will have to complete all works by 20th of March 2022 to ensure they are paid before the scheme closes.

  4. UPDATE: March 2021The scheme will close to new applications as originally planned at 5pm on the 31st March 2021.

    While the vouchers are valid for 3 months it is likely that they will be extended to allow the backlog of installations to be carried out

    UPDATE: December 2020The Prime Minister has announced the Green Homes Grant Scheme will be extended until 31st March 2022.

    At the moment all work under the Green Homes Grant Scheme must be completed by the 31st of March 2021, which is the end of the financial year and the budget that HM Treasury has available for this scheme.

    Due to COVID-19 restrictions and likely weather disruption (eg. some measures cannot be installed if the temperature falls below 5℃) it is probable that not all installs will be able to be completed within the tight timeframe allowed.
    HM Treasury is indicating it will not move the deadline, but there are indications that if sufficient installs can be carried out before March, more funding might be made available for similar schemes in future financial years.
  5. The government is concerned about those who cannot afford to contribute to the scheme so they have announced a Low Income Voucher worth £10,000 without any need for the homeowner to contribute, and any household on the following benefits may be eligible to apply for this voucher:

    Income Support
    Income-Based Jobseeker's Allowance (JSA)
    Income-Based Employment and Support Allowance (ESA)
    Universal Credit
    Pension Guarantee Credit (excluding Pension Savings Credit)
    Child Tax Credit
    Working Tax Credit
    Disability Living Allowance
    Personal Independence Payment (PIP)
    Attendance Allowance
    Carer's Allowance
    Severe Disablement Allowance
    Industrial Injuries Disablement Benefits
    Contribution-Based Jobseeker's Allowance (JSA)
    Contribution-Based Employment and Support Allowance (ESA)
    Housing Benefit
  6. To be eligable for a voucher you must own your home (including park home owners, long-leaseholders and shared ownership) or be a private or social landlord

    Your property must be in England (Scotland, Wales and Northern Ireland are not involved in this scheme)

    New-build properties that have not previously been occupied are not eligible for the scheme.

    You cannot apply for the scheme if you have already received a grant from your local authority as part of the Local Authority Delivery Scheme.

    If you are a private rent landlord your property must have an EPC band E,F or G
  7. There are several steps the homeowner needs to go through before they can apply for a voucher.

    1. Homeowners have to do an assessment to check they are eligible for the scheme. This can be done by visiting the Simple Energy Advice website and completing their online questionaire to check which measures they are eligble to install.
      However if you already have an Energy Assessment with recommendations for measures included in the scheme you can use that instead.

    2. The homeowner needs to talk to a suitably qualified installers to come up with a plan of action and get a quote for delivery of the plan . (The EEA can help you find qualified installers in your area)

    3. Finally the homeowner can place the application for the voucher on the Green Homes Grant Website
  8. The Scheme Administrator is the organisation tasked with overseeing the delivery of the Green Homes Grant Voucher Scheme.

    The Sheme Administrator approves all the applications, and is responsible for releasing the payment to the installers when they are ready to redeem the voucher.

    The Scheme Administrator for the Green Homes Grant Scheme is ICF Consulting Services Limited.
  9. The vouchers cover home improvements in 2 categories

    Primary Measures

    These cover Insulation or Low carbon heating and include:

    solid wall insulation (internal or external)
    cavity wall insulation
    under-floor insulation (solid floor, suspended floor)
    loft insulation
    flat roof insulation
    pitched roof insulation
    room in roof insulation
    insulating a park home
    air source heat pump
    ground source heat pump
    solar thermal (liquid filled flat plate or evacuated tube collector)
    biomass boiler
    hybrid heat pump


    Secondary Measures

    These cover Windows and Doors and Heating controls and include:
    draught proofing
    double or triple glazing (where replacing single glazing)
    secondary glazing (in addition to single glazing)
    energy efficient replacement doors (replacing single glazed or solid doors installed before 2002)
    hot water tank thermostat
    hot water tank insulation
    heating controls (such as, appliance thermostats, smart heating controls, zone controls, intelligent delayed start thermostat, thermostatic radiator valves)

    If you install at least 1 primary measure, your voucher can be used to help cover the cost of any of the secondary measures, as long as the cost of the secondary measures does not exceed the amount you get for primary measures.

    The voucher can be used to pay for labour, materials, scaffolding and VAT
    Additional works will be covered by the voucher if they are necessary for the installation of measures.
  10. Yes. But not only that, they must be registered with Trustmark first.

    Air Source Heat Pumps, Ground/Water Source Heat Pumps, Solar Thermal (liquid-filled flat plate or evacuated tube collectors) and Biomass Boilers should also be MCS certified as well.

    Under Trustmark rules all installers have to opperate to PAS 2030:2017, 2030:2019 or PAS 2035:2019 standards.
  11. There are a couple of reasons why homeowners can't find local installers.

    The Government has introduced this scheme to create jobs as well as to improve the energy efficiency of UK homes.

    The industry is not very big, so it has to hire and train more installers to be able to deliver this scheme.

    In order to protect homeowners, the government has insisted that only certified professional installers should be allowed to carry out the work under this scheme.

    This means that installers have to go through a stringent certification process, for each type of measure they wish to install, and this takes time.

    There are suitable installers for all the measures across the whole of England, however, as the registration only went live on the 30th of September not all the installers have been able to complete the registration process so quickly.

    There is a recognised shortage of insulation installers qualified to carry out work for park homes in particular, as the standards of expertise required for them are much more stringent due to the nature of the buildings, so qualification takes slightly longer.

    The insistance on properly certified installers is important, as homeowners do not want untrained people working on their houses, when badly installed energy efficiency measures could cause structural damage and health problems in their homes. (Also mortgage and insurance companies don't like botched building works that could reduce the value of a property)

    If you are having trouble finding an installer, please talk to us at the EEA and we will see if we can help you find someone in your area.
  12. No. To qualify for the voucher you need to use a registered installer.
  13. No, the Green Homes Grants are only available for homeowners, though landlords of residential properties can apply for them, as can Housing Associations
  14. To register as a Green Homes Grant Scheme Installer, the installer must first be certified with Trustmark for each type of measure they wish to install.

    To get Trustmark certification the installer should already be installing under PAS2030 or PAS 2035 standards and should talk to their industry certification body, or another Trustmark Scheme Provider, and they will help them register with Trustmark.

    For low-carbon / renewable heat measures such as Air Source Heat Pumps, Ground/Water Source Heat Pumps, Solar Thermal and Biomass Boilers the installer must also be an MCS certified Contractor.

    Once they have a Trustmark registration number the installer can then apply online to the Green Homes Grant Scheme Administrator for registration with the scheme.

    If installers don't register with the Scheme Administrator before the customer applies for the voucher, the installer may have issues getting the voucher reimbursed.
  15. Yes, as the installers need to order materials to be able to do the work you want them to do, many installers will ask for a deposit to cover those costs.

    However, homeowners should not be asked to pay anything until their voucher application has been successful.

    Installers cannot ask for deposits which exceed the value of what the homeowner would have to pay as their contribution. This is not a cash-back scheme.

    The installer will only receive the voucher reimbursment after the completion of the work, and after the homeowner has paid their contribution.

    Where the homeowner has a £10,000 Low Income voucher, they should not be asked for a deposit.
  16. The installer will agree a price for the work with the homeowner prior to the homeowner making their voucher application, so the voucher contains the name of the installer. and the agreed value to be reimbursed.

    The homeowner keeps hold of the voucher (it is actually not a physical voucher but an electronic one online) and they make any agreed deposit or pre-payment required to the installer.

    Once the work is completed the homeowner will be sent an invoice for the full amount of the project.

    The homeowner then deducts the value of the voucher, along with the value of any pre-paymens already made before settling the invoice.

    The homeowner will then be asked to sign off a certificate of satisfaction and send the installer the voucher.

    The installer can then submit the voucher to the Scheme Administrator who will review the work carried out, and if they are satisfied, they will then authorise the release of the reimbursment to the installer. That final process can take up to 10 days.

    If the voucher expires or the homeowner fails to pay the installer in time, the homeowner becomes liable for the full cost.
  17. When they apply for the voucher the homeowner must agree to pay at least 1/3rd of the cost of the project. If they fail to pay their contribution on time, they invalidate their voucher and become liable for the whole cost of the project. Many installers will ask for deposits or pre-payments to help the homeowner avoid being landed with the whole cost.

    Of course, this is not an issue for those with the £10,000 Low Income Voucher as the voucher will cover the whole cost of the project without any contribution from the homeowner, provided the total project cost is under £10,000. For projects over that value, the homeowner is liable for the difference.
  18. The process is long and complex so we have broken it down into stages.

    The voucher application process

    1. Homeowner checks their eligibility on the SEA website

    2. The homeowner finds a registered installer and gets a quote

    3. The homeowner fills out the application form and lodges the quote with the Scheme Administrator online

    4. The Administrator assesses the application and issues the voucher

    5. The Installation

    6. The installer asks for a deposit, and purchases the necessary materials

    7. The installer carries out the work to the required standards

    8. The installer files a report with Trustmark who check the quality of the work

    9. Completion

    10. The installer issues all the necessary certification to the customer

    11. The customer signs off on the work completed

    12. The installer raises an invoice for the full amount

    13. The customer pays their contribution and passes over the voucher

    14. The installer applies for reimbursement of the voucher

    15. The Scheme Administrator verifies the claim and makes the payment

  19. The installer can not redeem the voucher until the homeowner signs off to say that they are happy with the completion of the work.

    If you have concerns about installers at any point, you can contact Trustmark, who certify all the installers, and they can take steps to ensure the installer is doing the work correctly.

    The voucher is issued with the installers details on it. If as a homeowner, you hve to change installer part way through the delivery of the measures for any reason you will have to contact the Scheme Administrator and ask for the changes to be made to the voucher.
  20. No, you only need one quote that covers each measure you are installing.

    When you apply for a voucher the Scheme Administrator will compare that quoted price with other quotes on their system to ensure the homeowner is not being over charged.

    The government still recommends you seek out 3 quotes before making your choice of installers, but given the very tight deadlines and the limited number of registered installers it is not a requirment and a single quote is sufficient for this scheme.
  21. The Green Homes Grant Voucher Scheme does include a provision for insulating Park Homes.

    HOWEVER, all installers working on insulating Park Homes MUST HAVE Trustmark registration under PAS2030:2019 part B13 : Park Home Insulation Installer and follow PAS2035 standards.

    So it is not good enough just to be a Trustmark approved External Wall Insulation Installer, for example.

    If you are a Park Home owner you need to look for an installer that is listed as a Trustmark B13 Park Home Insulation Installer, nobody else can provide the work with the necessary guarantees and insurances to allow you to get the grant voucher.

    If you are an installer wanting to install insulation in park homes, you need to contact CIGA and apply through them for accreditation and Trustmark Registration.
    (At present CIGA is the only Trustmark Scheme Provider that is providing Trustmark Registration for Park Homes Insulation Installers.)
  22. The installer cannot start work until the voucher has been issued.

    It will take about 10 days for the voucher to be issued from when you put the application in.
    (For applications submitted in October there will be a longer delay in receiving your voucher as the Scheme Administrator is having to manually process the applications while their automated systems are developed. The first homeowners should start receiving their vouchers in the later part of October.)
    (update - the voucher system went live on the 9th of November and is now issuing vouchers applied for in October.)
  23. VAT on the installation of many energy efficiency measures is not necessarily charged at the usual 20% rate, instead installers can in many circumstances charge 5% VAT if both their customer and the intalled measure qualify.

    This means that the price the homeowner is charged is often lower than it would be normally .

    Installers will provide quotations and will show which elements of their installation are charged at the lower rate, and which are charged at the normal rate.

    The Installer usually has to buy the materials at the higher rate, but they can claim that back when they sell at the lower rate.

    The 5% rate is available on the installation of all the primary measures in the Green Homes Grant Scheme and most but not all the secondary measures.

    Installations paid for by contributions from landlords do not qualify for the reduced rate.

    There is more VAT information on the HMRC website: Energy-saving materials and heating equipment (VAT Notice 708/6) How to account for VAT if you are a contractor installing energy-saving materials and grant-funded heating equipment.

    Please note: BEIS have said that HMRC is not allowing the 5% rate on Retrofit Co-ordinator fees
  24. Cavity Wall insulation has been badly installed in many houses in the passed where unqualified installers were used. This is one of the reasons all installers working on the Green Homes Grant Scheme must be properly qualified.

    If your cavity wall insulation has failed, due to poor installation, you will need to remove or extract the old insulation before you can refill the cavity.
    That process is not covered by the scheme.

    If, over time, your insulation has just settled into gaps and lower parts of the building you might be able to top up the insulation to the required level under the scheme, without extracting existing insulation. Have a proper survey carried out to ensure that you do not need to extract the old insulation before trying to top up.

    If you have to extract insulation you might be able to get the cost covered by your insurance company, or via the guarantee on the original work.

    If the homeowner, or insurer, has already arranged for the extraction of the old insulation, then the scheme can be used to pay for the installation of new cavity wall insulation.
  25. For installers, the scheme administratrors have created a mobile phone application that they can use to record and submit the photos and information about the install that they need to up load for the voucher to be processed.

    The app can be downloaded from the main mobile phone app stores. It is called ICF SIghtline.

    There is a video tutorial for installers on the Government's YouTube Channel
  26. Yes it does.
    The scheme requires the Heat pump installer to replace your existing gas boiler with a more energy efficient one if you are only applying for a Heat-only Heat pump.
    This replacement must be carried out regardless of the age of your existing boiler and even if it is perfectly suitable for your reduced needs once the heat-pump is installed.
    This is a Government policy decision, and one that makes no-sense from an economic or environmental point of view, but we have been told repeatedly that this policy will not be changed.
  27. No.
    Any doors being replaced must be of "solid material", so that usually means wood.
    Existing uPVC doors are not eligible for replacement.
