Energy efficiency

Energy gained from the sun or wind is a renewable energy source and can help you save money in the long term. The ECO and BUS government grants help with the cost of installing or swapping to renewable or low-carbon options. There are various options available for renewable sources of energy which include the following:

Solar Panels (PV)

Solar panels are fitted onto a south-facing roof and generate electricity from the sun, they are low maintenance and on a sunny day you generate “free” electricity. Not every property is suitable for solar panels, the roof must be roughly south-facing, structurally strong enough to take the extra weight of the panels and not be obstructed by shade. The Centre for Sustainable Energy website has downloadable PDF leaflets on solar panels PV and battery storage where you can read further information. 

Heat pumps

Heat pumps can be ground-source or air-source and are a newer type of heating, so they are not very common. They work like a fridge but in reverse, making the air warmer not cooler. They need to be planned into a property but are much more efficient in the longer term, so over time they will help reduce high energy costs. For a heat pump to work efficiently, your home must be well-insulated and have a hot water cylinder. The Centre for Sustainable Energy website has downloadable PDF leaflets on air-source heat pumps and ground-source heat pumps where you can read further information.

Statement of Intent

We work in partnership with other councils in West Sussex to deliver the Energy Company Obligation Flex and Great British Insulation schemes. The Statement of Intent [pdf] 356KB sets out our flexible eligibility criteria for the Energy Company Obligation (ECO4) scheme from April 2022 to March 2026 and the Great British Insulation Scheme until March 2026. 

Grant description

The Energy Company Obligation (ECO) is a government scheme. This scheme requires some energy suppliers to help with the cost of improving a home's energy efficiency. These suppliers will provide grants to pay the whole cost or some of the cost towards these improvements, which can include wall insulation and boiler replacements. 

Who can apply

You can apply for this grant if the homeowner's annual household income is below £31,000 and someone in your house is vulnerable.

Who is eligible

The eligibility criteria for ECO is quite complex. The scheme requires a household to be on a low income and experiencing vulnerability or fuel poverty.  You may be eligible if you meet one of the following criteria:

• have a household income of less than £31,000 or you receive means-tested benefits 
• and the property has EPC rating of D, E, F or G (E, F or G only for rented properties)
• and  someone in your household is vulnerable (under 4 or over 65 years of age; has a health condition that makes them vulnerable to the cold)
• or  you may be referred by your energy company or by the CAB if you are struggling to pay energy bills.

How to apply

You can apply directly through your energy supplier, see the Ofgem website for a list of ECO suppliers or contact the Citizens Advice Energy Advice Service.

The energy efficiency of homes in England is measured and published as an Energy Performance Certificate (EPC).  

All domestic and commercial buildings need an EPC when a property is built, sold or rented. The highest and most efficient rating is band  A, the lower the rating, the less energy-efficient the home is. If your home is rated D, E, F, or G you may be eligible to receive government help to improve its EPC rating.  

View your home's EPC on the government website.

Maintaining a warm and comfortable living temperature in an energy-inefficient home can be difficult. Common issues for poor energy efficiency could be due to the following:

• too little insulation in the roof, walls, and floor
• windows that are single-glazed
• faulty or broken boilers
• drafts through windows, doors, chimneys and floorboards

You can find out more information about  Energy Performance Certificates on the Energy Saving Trust website.

If you live in an energy-inefficient home

All EPC's include recommendations to improve a home’s energy efficiency and the approximate cost of making the change. If you live in a lower EPC property you may be eligible to receive a grant to help pay for improvements. These grants often update so contact us for the latest information.

Scams about energy efficiency and new schemes for solar/heat pumps and boilers can come in the form of door-knocking, letters, emails, flyers and phone calls.

If an energy efficiency installer contacts you, they may promote the Energy Company Obligation (ECO) Scheme. To deliver this scheme they must be working in partnership with an energy company or be registered with the National Energy Foundation's (NEF) installer list. You can check that they are on the list by contacting the Citizens Advice West Sussex Energy Team on 0800 145 6879.

We recommend you ask the contractor which energy supplier they are working with and to double-check this by contacting the supplier directly. To find contact details of trusted energy suppliers see Ofgem's list of energy suppliers website page.

If you have been approached by installers to do work in your home or are looking for installers, we advise you to check that the company is registered with Trustmark (Government Endorsed Quality Scheme) before any work starts.

If you are looking to install renewable energy (heat pumps or solar panels), check that the company is registered with the MCS Accreditation Scheme or if you are looking for companies to provide insulation in your home they should be registered with the National Insulation Association (NIA).  

Being warm enough should not be a luxury but if you are on a low income and experiencing financial difficulties sometimes it can feel that way.  Please see the useful advice below that may help.

Reduce your outgoings by:

• making sure you are on the cheapest energy tariff available
• knowing where and when your energy is spent
• ensuring your home is fully insulated (loft, cavity wall, walls, windows, doors and drafts excluded)
• reducing the energy you consume see energy-saving tips from the Energy Saving Trust website

Increase money coming in by:

• ensuring you claim all the benefits, savings and discounts you are entitled to
• earning as much as possible using the resources you have

Maximise anything free by using:

• local food banks and community fridges that give away food for free and prevent food waste
• free activities that are available in your local area such as museums, libraries and events at community centres

Getting help towards paying a fuel bill is sometimes available via a one-off fuel voucher from ourselves or Arun & Chichester Citizens Advice.  If you are struggling to pay your bill, please contact us for free advice.  

A range of energy grant help is available but it often changes rapidly. The energy grants available below are current as of April 2024. For advice or help in completing any grant application or funding enquiry, please contact Arun and Chichester Citizens Advice Energy Team in the first instance.

Residents on a low income and who live in Bognor Regis or the surrounding area may also be eligible for SSEN Enabling Works funding. This can help pay towards clearing lofts, moving furniture or other work that enables the grant measures to be installed where the homeowner is unable to do this themselves. The funding application must be submitted by the installer or the organisation processing the grant application.

Request home energy help

If the total annual income of all working adults in your household is less than £36,000, or you are in receipt of a means-tested benefit, you may be eligible for:

• Energy Company Obligation (ECO) grant
• Great British Insulation Scheme (GBIS)
• Warmer Homes (Home Upgrade Grant - HUG) - only available for homes that do not use gas for heating
• our heating repair or replacement grant (Safe, Suitable Warm grant – SSW)

If the total annual income of all working adults in your household is over £36,000 and you are not eligible for full grants, you may wish to consider the following:

• Boiler Upgrade Scheme (BUS) – this is a government grant to provide financial support towards the installation of a heat pump when replacing a gas boiler
• Great British Insulation Scheme (GBIS) can provide free or reduced-cost insulation to properties in council tax bands A-D
• Solar Together - a West Sussex group-buying scheme for renewable solar panels and batteries

Landlords are required by law to ensure their rental properties have an energy performance certificate rating of at least E. This means that F and G-rated properties cannot be let.

Please see further information on Minimum Energy Efficiency Standards (MEES).

Privately rented

If you live in a privately rented property the following options could help: 

• your landlord can get funding towards the installation of a heat pump when replacing gas boilers through the Boiler Upgrade Scheme (BUS)
• if you meet the low-income eligibility criteria, your landlord may also be eligible for the Energy Company Obligation (ECO) grant or the Warmer Homes Home Upgrade Grant (HUG) -if the property does not use gas for heating

Landlords applying for grants can be required to contribute up to 50% of costs. The part-funding contribution is still a significant help towards installing measures that will make the property more energy-efficient.

Please note landlords with a property portfolio of more than 4 houses are not eligible for the Warmer Homes Home Upgrade Grant.

Both you and your landlord must give permission and provide evidence that the eligibility criteria are met.

Social housing

If you live in social housing you can:

• contact your housing provider to find out what they are doing to make their properties more energy efficient
• see if you are eligible for the Energy Company Obligation (ECO) grant if your rent is above the market rate (if so it would be considered as private-rented sector and you or the landlord may be required to contribute 50% of costs)

Please note that you will not be eligible for most grants because the government has a separate grant for social housing providers.

Shared ownership  

If you live in a shared ownership property and do not have responsibility for the maintenance of your property, you will not be eligible for most grants. However, you could be eligible for the Energy Company Obligation (ECO) grant if your rent is above the market rate. In this case, it would be considered as private-rented sector and you or the landlord may be required to contribute 50% of the costs.

If you are responsible for the maintenance of your property, you may be eligible for some of the grants listed on this page. Please enquire directly to the contact details provided for each grant/scheme for further clarification.

We have a Landlord Accreditation Scheme which provides support and recognition to landlords who are meeting standards relating to the condition and management of their properties.
