Grants, loans and subsidies for energy use

Help is available with energy use and improving energy efficiency of your home, from May 2022. 

Boiler Upgrade Scheme (BUS)

The Government’s Boiler Upgrade Scheme (BUS) is available and the latest information is on their website.

Boiler Upgrade Scheme (BUS) | OfgemThe Boiler Upgrade Scheme will provide upfront capital grants. These are to support the installation of heat pumps, and in some circumstances biomass boilers.   

Cornwall Council has no direct involvement in this scheme, please contact installers direct.

Health led referrals

For any Cornwall Council led programme you or someone living in your home may have either: 

  • have a long-term health condition
  • be at risk of poor health
  • be caring for a vulnerable person
  • be children aged 19 or under
  • be worried about their home being cold or damp

Help to heat (LA Flex) Cornwall Council

The Energy Company Obligation (ECO) Help to Heat is a government energy efficiency scheme.

Help to heat is also sometimes known as Local Authority Flexible Eligibility (LA Flex). They both refer to the same scheme.

Under the ECO scheme, obligated suppliers fund the installation of energy efficiency improvements. These include loft or wall insulation.

Types of improvement

  • cavity wall insulation
  • loft insulation
  • replacement heating or boiler

Most homes will qualify for this scheme.

Ofgem's Energy Company Obligation (ECO) page and guidance issued to local authorities will tell you more about this scheme

Draft ECO4 Guidance: Interim Delivery | Ofgem

Please see our updated joint Help to Heat statement of intent (Cornwall and Isles of Scilly). This explains how we can help qualifying residents and was issued on 3 January 2023.

Cornwall Council and Council of Isles of Scilly’s Statement of Intent 2023

Fuel poor households could be eligible for Energy Company Obligation (ECO) funded home improvements.   

Cornwall Council identifies, assesses and approves such households, through our partner Inclusion Cornwall.

(Please note: Sustainable Warmth Fund has a different approach to income eligibility)

Eligibility for any of our Winter Wellbeing programmes is based on the following:

You may be eligible if you meet the following conditions:

  • you or someone living in your home may have either:
    • have a long-term health condition
    • be at risk of poor health
    • be caring for a vulnerable person
    • be children aged 19 or under
    • be worried about their home being cold or damp
  • you are an owner-occupier, a private landlord or rent from a private landlord
  • have a household income of £31,000 or less once your mortgage or rent, utility, care and council tax payments are deducted

How we assess

  • Are households facing high energy costs, to stay warm?
  • Is there a greater likelihood that a household is in fuel poverty?
  • Is the household receiving a low annual income, after housing, energy, utilities, care and Council Tax costs have been deducted?
  • Does fuel poverty apply?

To qualify as being in fuel poverty you live in a home with an Energy Performance Certificate (EPC) rating of D, E F or G.

Vulnerable to the cold

To qualify as vulnerable to the cold, you must meet any one of the following conditions:

  • you have a recognised long term illness
  • you are either over 65, have at least one child under the age of 19 or are pregnant

Low Income Low Energy Efficiency

To qualify as being in a home that has a low energy efficiency you need to meet the following conditions:

  • the home has an Energy Performance Certificate (EPC) rating of D, E F or G
  • the household has a low annual income.

Warm Homes Fund (homeowners and private landlords or private tenants)

The purpose of the Fund is to reduce fuel poverty by upgrading homes. The completion of 189 upgraded homes with gas and air source central heating and insulation started in Winter 2021/22 and will finish in March 2023. No further schemes are currently funded.  

Warm Homes Fund (Park Homes)

The purpose of the Fund was to reduce fuel poverty by upgrading homes to mains gas central heating.  Phase 1 for 43 park homes at Sun Valley, in St Columb was completed in October 2021. In March 2022, Phase 2 started at Tremarle in Camborne. This was to upgrade another 43 park homes from LPG and electric heating to mains gas central heating and insulation. This is to make their homes warmer. No further schemes are currently planned or funded.

The scheme helps residents that have a LPG central heating system have their boiler converted if suitable to a new condensing gas boiler.   

Customers who have Electric Storage Heaters or an LPG system cannot be converted . These customers will have these replaced by a new condensing gas boiler and radiators (if required).  

Customers who currently use a LPG Gas for cooking will have this converted to mains gas. Should this not be possible it will be replaced with a like for like appliance to the value of £300. (Alternatively, a contribution of up to £300 towards a replacement for the householder to buy themselves.)

We have had three successful bids for funding from the Warm Homes Fund. These were led by:

  • Public Health at Cornwall Council
  • Inclusion Cornwall
  • OVO Energy Solutions

Sustainable Warmth Fund (New)

The Sustainable Warmth Fund is the new grant-funded energy efficiency scheme from the Government. 

This fund aims to:

  • improve the EPC rating of your home with a range of energy saving measures
  • reduce (or offset rising) heating costs, making your home warmer
  • improve your general health and wellbeing

Cornwall Council works in partnership with OVO Energy Solutions to deliver this scheme to homes in Cornwall and the Isles of Scilly.  

This scheme runs until March 2023 and aims to help around 400 homes.

View the OVO Energy website


If you own your own home and live in it full-time or if you are a private or social housing tenant, then your home might be eligible for the scheme.

If you are a private or social landlord then your property(s) may also be eligible.   It is not for holiday or second homes.

  • you or someone living in your home must either:
    • have a long-term health condition
    • be at risk of poor health
    • be caring for a vulnerable person
    • be children aged 19 or under
    • be worried about their home being cold or damp
  • a total household income of no more than £31,000* gross (so including tax and any other deductions)
    * please note this is tighter income criteria than our usual programmes set by the funder - Government)
  • your home has an Energy Performance (EPC) rating of G, F or E (some D’s can be accepted).  To find your EPC rating visit the Government website or we can check for you.

What will happen if eligible and qualify?

If your home is eligible then a full house retrofit survey will be done to find out any possible measures.

The results of the survey will ensure that we recommend the best possible options in order to make your home as energy efficient as it can be.

Too many homes in Cornwall and Isles of Scilly are not properly insulated. This results in a loss of heat through the walls and roof etc. This is both a waste of energy and money.   

This is why we are going to focus on fabric (insulation) first.  

There is little point fitting a brand new heating system if all the heat flies back out again, leaving you cold and out of pocket as soon as you turn it on! This doesn’t mean we can’t fit heating, we just want to make sure that whatever we suggest is the best possible option for you and your home.

Possible measures

We cannot install any solid fuel/gas measures under the scheme (but we can work on homes that currently have them) to remove or replace this heating.


If you are a homeowner or tenant then this will be free of charge.

If you are a landlord, you will have to fund one third (33%) of the total installation cost.   

The cost will vary depending on the type and number of measures installed. However, an approximate cost will be provided after the retrofit survey is complete and before you sign any contracts.

Revised Total



Energy switching

The energy price cap increased in March to £1,973 with a further increase expected in October.   

Yet with the energy market in crisis, there are still no deals cheaper.

As a result, the best option for most right now is to do nothing, and either stay on a capped tariff or move to it when their current deal ends.

I am worried about money

To save energy around the home, as well as contacts for other energy and money advice services that can offer assistance.

  • Avoid using standby on electrical devices - devices on standby mode can use almost as much energy as when they are being used. To help with this we have standby saver plugs which turn devices off from your remote.
  • Reduce showering time by one minute - Showers are some of the most energy hungry appliances in our homes. Reducing the amount of time you are in the shower will help you save energy and water.
  • Replace one bath a week with a shower - Baths use up far more water than showers (about two and a half times more). Showers are even more efficient if you use a shower aerator.
  • Wash up in a bowl rather than the sink - A washing up bowl takes less water to fill which will save you money.
  • Turn the thermostat down by one degree - This could reduce your heating bill by up to 10%. You can use thermostats and Thermostatic Radiator Valves (TRVs) to keep the rooms you use most warm while saving energy.
  • Wash clothes at 30°C - Reducing the temperature of your wash from 40°C to 30°C could cost you 40% less. A cooler wash helps keep clothes looking newer for longer.
  • Only boil as much water as needed - Two thirds of people overfill their kettle, often boiling twice as much as needed. Boiling only as much as you need means your kettle will boil quicker too!
  • Turn off lights that aren’t being used - It’s always best to turn off lights that aren’t being used, even if only for a short time. This is even more important if you have any older, less energy efficient lightbulbs.
  • Dry clothes outside where possible - Tumble dryers are amongst the most energy intensive appliances in the home. Drying clothes outside could reduce the amount of condensation in your home and can help reduce issues with damp and mould.
  • Maximise washing loads - Ensuring that your washing machine or dishwasher is always full before you put it on means you’ll have to do fewer washes. These appliances use the same amount of energy regardless of how full they are.
