You can find funding schemes to help improve the energy efficiency of your home. 

Sustainable Warmth

Sutton residents can now apply for a government Sustainable Warmth Grant to make their homes warmer and greener.

The grant is:

  • delivered by Warmworks, and
  • funded by the Department of Business, Energy and Industrial Strategy

The grant can be used to deliver a wide range of insulation measures and renewable heating systems to reduce the amount of energy used in your home.

The scheme is available to homeowners and private tenants who are:

  • on a low income and
  • live in a property which is hard to heat

Homes considered hard to heat are those with an Energy Performance Certificate (EPC) rating of D, E, F or G. This often means you also have high energy bills. The grant of up to £10,000 is used to install renewable energy or insulation upgrades.  You can visit the EPC register site to check your home's EPC rating.

Check if you're eligible

In order to be eligible for the grant, your total gross household income must be:

  • below £30,000 per year, or 
  • below £20,000 per year, after:
    • deducting tax
    • national insurance
    • your mortgage (or rent) payments, and
    • Council tax

If you're eligible

Warmworks will arrange a survey of your home, and give you a choice of upgrades suitable for your property.  If you choose to go ahead, an accredited and registered contractor will install the agreed heating and energy-efficiency measures.  An independent inspection will check the completed work to ensure it meets expected standards.

If you own your property and meet the eligibility criteria you will pay nothing. If you rent your property, you can contact your landlord and tell them about this programme. If you qualify your landlord could be entitled to grants of up to £5000 and it will only cost them one third of any upgrades installed. 

If you are interested to find out more and think you may be eligible for this scheme,  complete the online form on the Surrey energy saving trust website or call 0808 196 8255.

About Warmworks 

Warmworks have been contracted by the Greater Southeast Energy hub, who are administering this scheme for the southeast of England, on behalf of the Department of Business, Energy and Industrial Strategy.  Warmworks is a joint venture between the Energy Saving Trust, Everwarm and Changeworks. Warmworks launched in 2015 to deliver the Scottish Government’s national fuel poverty scheme, Warmer Homes Scotland. This scheme provides insulation, efficient heating and renewable technologies in the homes of households who are struggling with the cost of high energy bills, making homes warmer, more comfortable and more affordable to heat. Since 2015, they have delivered energy-efficiency and heating measures to almost 25,000 homes across Scotland.

ECO funding

The Energy Company Obligation (ECO) is a government scheme that requires some energy companies to provide funding for energy efficiency improvements to eligible households. If you are on qualifying benefits you may be eligible. 

Find out more about ECO funding on the Ofgem website.

ECO grants are available to cover all or part of the cost of energy efficiency measures. The most common measures are:  

  • loft insulation  
  • cavity wall insulation 
  • solid wall insulation  
  • replacement of a broken boiler

Your energy provider should inform you if the grant is available to you but you can also find out if you are eligible and apply on the Simple Energy Advice website.

The Greater London Authority (GLA) is also allowed to declare additional households in London as eligible for ECO funding, under the ECO Flexible Eligibility scheme. This applies to owner occupiers and private tenants only. To allow the GLA to declare eligible households, they have published a Statement of Intent on the GLA website, setting out the eligibility criteria for funding.

If you are struggling to keep warm in winter, you can also contact our Sutton Healthy Homes advice service partner Thinking Works on:

Boiler Upgrade Scheme

The government is providing grants to encourage homeowners to install low carbon heating systems such as heat pumps. This is through the Boiler Upgrade Scheme (BUS). These grants can help homeowners overcome the upfront cost of low carbon heating technologies.

The grants available can fund:

  • £5,000 off the cost and installation of an air source heat pump
  • £5,000 off the cost and installation of a biomass boiler
  • £6,000 off the cost and installation of a ground source heat pump

These technologies should only be installed in homes that are fully insulated. This is because they emit a low level, constant heat, rather than providing heat on demand, like a gas boiler.  One of the criteria for funding eligibility is that your home must have a current energy performance certificate (EPC), with no outstanding recommendations for loft or cavity wall insulation.

Check your EPC report on GOV.UK

It is essential that you ensure that you use a fully certified MCS installer to undertake these works. This is to ensure that the chosen technology is sized, installed and commissioned appropriately for your home.
