Home energy efficiency

Making your home more energy efficient has a variety of benefits. It will not only help to reduce your carbon footprint, which is a crucial step in helping to tackle the climate emergency, but it could save you up to £600 on your bills and help you to keep a warmer, happier, healthier home.

There are a number of ways that you can get financial help to make your home more energy efficient.

Green Homes Grant vouchers

Homeowners in Dacorum, including landlords, can get up to £5,000 to pay part of the cost of energy-saving measures, such as insulation.

The Government will provide a voucher up to £5,000 that covers up to two-thirds of the cost of energy efficiency and low-carbon heat improvements to your home.

If you are a homeowner and you or a member of your household receives one of the qualifying benefits, the Government may cover 100 per cent of the cost of the improvements, up to £10,000.

What improvements can I get?

Vouchers must be used to install at least one primary home insulation or low-carbon heating measure.

If you choose to install at least one of the primary measures, you can use your voucher to help cover the cost of secondary measures.

The grant for the secondary measure is capped at the value of the grant provided for the primary measures. For example, if you receive a £400 voucher for a primary measure such as a cavity wall insulation, you will be able to receive a maximum of £400 for a secondary measure, such as an energy-efficient replacement door.

Primary and secondary measures

Expand all

  • Primary measures

    The voucher must be used to install at least one primary measure. This can be an insulation measure and/or a low carbon heating measure.

    Insulation measures

    • solid wall
    • under floor
    • cavity wall
    • loft
    • flat or pitched roof
    • room in roof
    • insulating a park home

    Low carbon heat measures

    • air source, ground source or hybrid heat pump
    • solar thermal
    • biomass boilers
  • Secondary measures

    If you install at least one primary measure, your voucher can be used to help cover the cost of any of the following secondary measures:

    • draught proofing
    • double/triple glazing (where replacing single-glazed windows)
    • secondary glazing (in addition to single glazing)
    • external energy-efficient doors (replacing single glazed or solid doors installed before 2002)
    • heating controls
    • hot water tank thermostats and insulation.

How to get a Green Homes Grant voucher

  1. Use the Simple Energy Advice website to check if you’re eligible for a voucher and what measures you could get done.
  2. Choose which improvements you would like and see an estimate of how much this may cost.
  3. Use the website to help you to find registered installers to get quotes from to carry out the work.
  4. Apply for your voucher and wait for approval before going ahead. You must have the work completed by 31 March 2022 (the deadline was previously March 2021 but this has now been extended).

If your application is successful, you'll be emailed the voucher - do not get any work done until you have received this. Once the work is complete, you'll need a dated copy of the invoice provided by the installer to redeem the voucher. The grant will then be paid directly to the installer on your behalf.

There is only enough funding for 600,000 households in England (just over two per cent of all homes), so make sure to apply as soon as possible.

ECO funding

The Energy Company Obligation (ECO) is a Government scheme to help reduce carbon emissions and tackle fuel poverty. Under ECO, energy suppliers fund the installation of energy-efficiency measures in British homes. The obligated energy suppliers work with installers to introduce certain efficiency measures into your home, such as loft or wall insulation, or heating measures.

What improvements can I get?

If you meet certain criteria, you could be eligible for low-cost or free home energy efficiency improvements, such as:

  • Boiler replacements
  • First time central heating systems
  • Loft insulation
  • Cavity wall insulation
  • Under floor insulation
  • Room in roof insulation
  • External wall insulation

Am I eligible?

You may be able to receive ECO funding towards home energy efficiency if you meet certain eligibility criteria.

    These criteria have been set by us as part of our ECO Flex Statement of Intent. 

    Past copies of this information can be found here: 

    Unlike the Green Homes Grant voucher scheme, there is no deadline to have ECO work completed. 

Can I use the Green Homes Grant Voucher and ECO together?

You cannot claim a Green Homes Grant voucher towards the cost of a measure that has also had funding under ECO. However, you can claim both ECO funding and a Green Homes Grant voucher as long as they are each for different measures - for example, loft insulation and cavity wall insulation.

How to get ECO funding

We work in partnership with YES Energy Solutions to make it easier for households to get the help they need for ECO funding. If you think that you may be eligible, contact YES Energy Solutions.

I'm a council tenant, what help could I get? 

Contact our Home Energy Conservation Officer on homeenergy@dacorum.gov.uk or call 01442 228338 to discuss what options may be available for you.

Minimum energy efficiency standards for the private rented sector 

Since April 2020, all tenancies must have a minimum Energy Performance Certificate (EPC) energy rating of E under the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015. The minimum standard is set to increase to an EPC energy rating of D by 2025 and C by 2030.

A home is required to have an EPC rating when it is constructed, sold or let. This is an example of an EPC. If you are letting a property, check the EPC rating in case you need to make improvements.

The Government website provides landlords with guidance on complying with the regulations.

Our grants page has more information about additional funding that may be available to you.

Energy efficiency quick wins

The Energy Savings Trust and Uswitch have outlined a wide range of easy actions that you can take today to help make your home more energy efficient - whether it is turning your thermostat down a degree, getting LED lightbulbs or turning your appliances off at the wall rather than keeping on standby.

Our energy-saving advice leaflet also has quick tips for how you can be more energy efficient at home:  Energy Saving Leaflet (PDF 711KB).
