Gas Boiler Installation Grants

Do you need to replace your ageing boiler or has it just let you down? You may find yourself wishing there was a grant or funding that could help with the cost. If, so, we have good news for you. Housewrapped have the expertise to help you get a new replacement mains gas boiler through the UK Government’s ECO3 grant replacement scheme.

The Grant Explained

You may qualify for a UK Government ECO3 grant to replace your mains gas boiler if you have an inefficient boiler 7 years or older, or yours has just let you down. If you meet the qualifying criteria, Housewrapped could help you secure Government grant funding towards the cost of a new energy efficient mains gas boiler for your home and identify other insulation measures which can help maximise the grant funding available.

Funding for this scheme is limited and has recently been reduced, so do not wait to find out if you qualify. You may miss the opportunity to have a new energy efficient boiler fitted at no or little cost to you. Whilst this scheme runs until 2022, recent removal of 75% of the originally allocated Government funds will place pressure on the remaining funding pot. So it would be wise act quickly to secure your funding.

Should I Consider a New Mains Gas Boiler?

Installing a new energy-efficient mains gas boiler can see your energy bills reduce by around 25%. For an average household, this can be around £300 a year, and with energy prices rising, the potential savings increase. New energy-efficient boilers offer low carbon emissions and for a typical 3-bed semi-detached home emitting approximately 4.5 tonnes of CO2 into the atmosphere each year, you can drastically reduce this by upgrading to a new energy-efficient gas boiler for your home.

Do I Meet the Criteria?

Can you answer ‘yes’ to the questions below?

  1. Are you or is any person living with you the homeowner?
  2. Is your existing gas boiler 7 years or older, or broken?
  3. Is any person living in your property in receipt of a state benefit?

If so, check our quick handy calculator to find out how much ECO3 grant funding may be available for your property.

To qualify for funding, you may also need to be able to install a secondary insulation measure alongside your boiler replacement. Installing an installation measure alongside your boiler replacement, under current Ofgem funding regulations, is vital to secure maximum funding and could greatly reduce the amount you will be required to pay. In many cases, this could mean you pay nothing.

How Much Help You Could Receive?

Use our handy calculator to see exactly how much you may be expected to contribute towards your gas boiler installation. Our calculator will tell you the amount of gas boiler grant available to you, based on your house type, number of bedrooms and your wall construction. You can see at a glance how much, if anything, you will need to contribute. Remember, the gas boiler grant can significantly reduce and in some circumstances remove the cost completely for your mains gas boiler installation as well as reducing your energy bills going forward.

Remember it is important to have an insulation measure installed at the same time to qualify for a drastically reduced or removed cost to you, if you need help to identify a qualifying insulation measure, we could help with this too.

Whilst we have designed our online gas boiler replacement calculator to be as accurate as possible, we will always carry out a Covid-19 safe on-site survey to confirm the cost before any work is undertaken.

Why Identifying a Secondary Measure is Important

Funding for boiler replacements only has been greatly reduced as the UK Government seek to encourage homeowners to ensure their homes meet energy-efficient insulation measures. Funding is still available for boiler only replacements, but you will need to contribute a greater proportion of the cost. Where we can identify a secondary need for insulation measure, the current ECO3 funding scheme allows a far greater grant contribution to be made. In a lot of cases, we are able to remove the client contribution altogether.

To qualify as a secondary measure, we need to identify that underfloor, cavity wall or room in roof insulation is required and the grant application must cover both measures. The work is required to be carried out alongside your gas boiler replacement. If you are unsure whether your property qualifies for these secondary measure installations please contact us.

Survey Process

To enable you to qualify for maximum funding under the ECO3 gas boiler replacement scheme and gain the most in energy savings from your new gas boiler, we also seek to improve the insulation efficiency of your property. Your newly installed energy efficient boiler will still lose unnecessary heat and you will still incur larger bills than necessary, if your property has inefficient or insufficient insulation. Our aim, wherever possible, will be to remove or greatly reduce any contribution you are required to make.

We will also determine the exact location of your current gas boiler and flue, and include considerations such as the age and location of radiators to establish the full level of funding that you are entitled to receive. For this reason, our online gas boiler replacement calculator is a guide, subject to confirmation by an on-site survey.

Boiler Installation

Installation is usually a simple process. We need access to the site of the existing boiler or re-location space to install your new boiler. We will also need to visit the site of all radiators, the flue and the gas meter as part of the installation and finishing checks. Our total installation time including testing is around five hours depending on the size of the property and any relocation required.


Your safety and that of our survey and boiler installation teams is our priority. We ensure we work under strict COVID-19 safety guidelines to minimise the risk of infection. We sanitise all units before they are moved in to your home. Our surveyors and installation teams all carry sanitiser and will wear required PPE whilst working within your property. They will sanitise hands before entry and throughout the installation. After work is completed, they will ensure all surfaces they come into hand contact with are sanitised before leaving.

Housewrapped work with leading installers and suppliers to carry out work on behalf of the ECO3 scheme. Why not get in touch to see how little you’d have to pay for a new boiler for your property?
