Financing Energy Efficiency Projects

Key Sources of Funding for Energy Efficiency Projects in the UK

The energy transition, climate change awareness and rising energy prices are forcing companies to develop and implement powerful energy management strategies. But what financing tools are available for you to boost your efficiency projects?

In this article, we will look at what is going on in the UK, what energy efficiency strategies were implemented and what financing options are available for you and your clients.

Countries and international organisations worldwide have set public policies and specific targets for energy performance, and businesses have a responsibility to contribute to many of them.

The European Union has set the objective to be climate neutral by 2050, and the UK’s objective runs in parallel. The initial goal was an 80% reduction on greenhouse gas emissions by 2050, but the target has become more ambitious to actually achieve net zero emissions by then. Alongside, the UK Government has set an objective to ensure all electricity is produced by renewable sources by 2035.

In this context, it is vital for companies to commit to controlling and reducing their energy consumption. This can be done by upgrading appliances and insulation, changing your energy provider, monitoring and optimising energy use. To be effective and ensure a real impact, you need to be aware of the existing financing levers to enable your energy optimisation plans.

Public Policy and Funding for Energy Efficiency Projects

To encourage companies to make the energy transition, states and regions have set up a wide variety of public funding and legislation.

In the UK, the Clean Growth Strategy and the Net Zero Strategy are the umbrella to further initiatives to cut emissions while remaining competitive economically. Several efficiency initiatives have been launched and others will be announced over the following months and years, from households to industrial emissions, transport, businesses and the state itself. Some of the key strands of this strategy are:

1. Plan for the Decarbonisation of Industrial Processes 

The Government Industrial Decarbonisation Strategy is focused on cutting down emissions, moving away from fossil fuels and speeding the electrification and use of hydrogen. Industrial processes account for one sixth of emissions in the UK, and aligning industrial growth with the net zero goal is a challenge the UK is tackling. 

Incentives and funding plans are being developed to ensure businesses, investors and consumers choose low carbon options, speeding up the process.

2. Public Sector Decarbonisation Scheme

The built environment is one of the largest contributors to GHG emissions (about 30%). This plan for the 2020-2025 period is a package of almost £1bn for upgrades to make the public estate energy efficient. Phases 2 and 3 are focused on decarbonising public buildings, including schools, government buildings and hospitals.

Public authorities applications are now closed, but you may still be able to access this programme through your local authority once allocations have been made in 2022. Get in touch with your Local Enterprise Partnership or local authority for further details.

3. Funds for Small and Medium Enterprises

The Carbon Trust is a useful source for advice and guidance on where to obtain finance for your SME energy efficiency project across the UK. The grant schemes in England and Wales have ended, but you can address your  Local Growth Hub for information and guidance as it is assumed new programmes will be launched.

If you live in Northern Ireland or Scotland, you can find information on SME loans through the Energy Saving Trust.

4. Environmental Tax Relief

Across the UK, businesses can get access to environmental tax discounts if you commit to reduce your carbon emissions. By entering a voluntary CCA (Climate Change Agreement) with the Environment Agency, you can obtain discounts on energy costs and tax reliefs. There are a series of limits, conditions and exemptions depending on the type of business, but it is definitely a source of energy savings to take into account. Some additional good news is that the scheme has been extended until 2025.

5. Access to European Funds

Although the UK is no longer part of the EU, it still has some links with European and international programs and can obtain funding through some of them. 

This is the case of the research and innovation programme Horizon Europe, with a strong focus on sustainability and energy efficiency actions. In this new position as Associated Country, UK firms can still participate and receive grants for their projects

Private Sources of Financing

1. Energy Performance Contracts and Third-party funding

Some actors propose to finance energy efficiency projects with the gains (or savings) obtained. It represents a balance between the energy efficiency guaranteed by the energy performance contract that must be achieved, and the cost, the service, the rent that will be paid to the service company.

EPCs (Energy Performance Contracts) are part of the framework of third party financing. Briefly, the contract involves an energy reduction and the repayment of the investment is based on the savings generated.

2. Return on Investment from previous Energy Savings

The aim of any energy optimisation project is to reduce consumption and therefore your bills. If we add into the equation the soaring energy prices, organisations have a real interest in optimising their consumption.

Businesses, as well as individuals, want to save money.

Energy efficiency strategies can help you save costs to then be able to allocate that money difference in another part of the business where it creates more value. This self financing option is an interesting one to consider as it limits your external dependencies and helps you focus on your goal. Who knows, maybe once you’ve achieved some energy savings… Those can be allocated to a larger energy efficiency programme!

3. Green Lending and Private Investment 

Green lending can be an option to consider for larger energy efficient programmes. Investors and banks are shifting towards sustainability projects and investing in firms who are (or want to be) more efficient. The project needs to meet a specific set of criteria, normally environmental and sustainability related, linking the loan to an obligation to deliver such sustainability objectives.

These projects are highly considered in the market and they increase the investor’s chances to obtain ROI. Also, investing in responsible firms contributes to their own ESG (Environmental, Social and Governance) promises and goals.

4. The Fintech Option

When we talk about fintech, we are referring to financial technologies. 

On the one hand, you have the option of Crowdfunding, a financing strategy with which you can seek funding through donations from people who are interested in your energy efficiency project. And from where you can obtain tax benefits or products of your interest produced after microfinancing. 

And on the other hand, you have the option of Crowlending. This modality is similar to crowdfunding, but through loans. In other words, you can publish your project online on platforms such as ECrowd, which specialises in campaigns related to renewable energy and energy efficiency projects, and make yourself known to sustainable investors.


The climate crisis, coupled with policy measures, is leading us towards an optimisation of energy consumption at all levels for the agricultural, tertiary and industrial sectors by 2030.

The implementation of energy efficiency and optimisation projects is therefore essential and can be achieved through the implementation of energy analysis, monitoring and optimisation solutions.

Moreover, thanks to the financing levers, companies can define real strategies for ecological transition in order to meet the established objectives: 

  • be more productive.
  • anticipate future ecological obligations and not be surprised by new laws and regulations.
  • create new opportunities for your business, while protecting the environment and being responsible.

This is the perfect time to develop your energy optimisation plans, or to put them in place if you have not yet done so.
