A Guide To Energy Efficiency Grants In 2025

Feeling the pinch of rising energy bills? You’re definitely not alone! Across the country, homeowners are grappling with the increasing cost of heating and powering their homes. It’s a worry that affects everyone, from families on tight budgets to those concerned about their environmental impact. But there’s good news! Thankfully, a range of government grants and initiatives are available specifically designed to help homeowners boost their energy efficiency and, crucially, slash those ever-increasing costs. These programs recognise the importance of making homes warmer, more affordable to run, and more environmentally friendly.

Let’s dive into the world of energy efficiency grants and discover how you can take advantage of these opportunities. We’ll explore the different types of energy efficiency grants available, who is eligible, and what kind of improvements they can fund.

Why energy efficiency matters

Before we jump into the grants, let’s quickly recap why energy efficiency is so crucial:

  • Lower bills: This one’s obvious! By reducing energy waste, you’ll see a significant drop in your monthly expenses.
  • Environmental impact: A more energy-efficient home means a smaller carbon footprint, contributing to a healthier planet.
  • Home comfort: Improved insulation and heating systems create a more comfortable and consistent temperature throughout your home.
  • Increased home value: Energy-efficient homes are increasingly attractive to buyers, potentially boosting your property’s value.

Navigating the grant landscape

The world of energy efficiency grants can seem a bit daunting, but we’re here to simplify it. Here are some key programs to explore:

  • The Home Upgrade Grant (HUG) is a government initiative designed to help low-income households in England improve the energy efficiency of their homes. Specifically targeting those properties not connected to the mains gas grid, HUG provides funding for a range of upgrades, including insulation (loft, wall, and underfloor), low-carbon heating systems (such as heat pumps), and even solar panels in some cases. The goal is to reduce energy bills, improve home comfort, and lower carbon emissions, ultimately tackling fuel poverty and contributing to the UK’s net-zero targets. This grant focuses on making substantial improvements to the least efficient homes, ensuring that vulnerable households can benefit from warmer, more affordable living spaces.
  • The Energy Company Obligation (ECO) is a government scheme in Great Britain that places a legal obligation on medium and large energy suppliers to help improve the energy efficiency of homes. It aims to tackle fuel poverty and reduce carbon emissions by requiring these companies to promote and fund energy-saving measures. These measures can include insulation upgrades, heating system improvements, and other energy-efficient installations. ECO works by setting targets for energy suppliers, who then deliver these improvements to eligible households, often focusing on those in low-income or vulnerable situations.
  • Local Authority Flexible Eligibility, often referred to as LA Flex, is a crucial component of the Energy Company Obligation (ECO) scheme. It empowers local authorities to broaden the eligibility criteria for energy efficiency grants, enabling them to reach a wider range of residents who may be struggling with fuel poverty or vulnerable to the effects of living in a cold home. While ECO4 has its own set of eligibility requirements, LA Flex allows councils to identify specific needs within their communities and tailor the scheme to address them. This flexibility is essential for ensuring that support reaches those who may not qualify under the standard ECO criteria but are still in dire need of energy-saving upgrades.

What kind of improvements are covered?

The grants can help you tackle a variety of energy-saving projects, including:

  • Loft insulation: A significant amount of heat can escape through the roof. Loft insulation acts as a barrier, preventing this heat loss and dramatically reducing your energy bills. Grants can help cover the cost of installing or topping up loft insulation to the recommended depth.
  • Cavity wall insulation: Many homes built between the 1920s and 1990s have cavity walls – two layers of brick or block with a gap in between. Cavity wall insulation fills this gap, preventing drafts and reducing heat loss. This type of insulation can significantly improve the energy performance of a home.
  • Solid wall insulation: Homes with solid walls (typically older properties) can be more challenging to insulate. However, solid wall insulation, either internal or external, can make a huge difference. Internal insulation involves adding a layer of insulation to the inside walls, while external insulation wraps the entire house in an insulating layer. Grants can help with the often higher costs associated with these projects.

Eligibility and how to apply

Eligibility criteria vary depending on the specific grant. Generally, factors like income, property type, and existing energy efficiency measures are considered.

Here’s a general guide to get you started:

  1. Research: Explore the grants mentioned above and visit government websites or contact your local council for detailed information.
  2. Check Eligibility: Carefully review the eligibility requirements for each grant to see if you qualify.
  3. Gather Documentation: Prepare any necessary documents, such as proof of income, property ownership, or benefit entitlement.
  4. Apply: Follow the application process outlined for each grant, whether it’s online, by phone, or through Zing Energy 

Tips for success

  • Don’t delay: Grant funding can be limited, so it’s best to apply as soon as you’re eligible.
  • Get advice: Contact energy advice organisations or your local council for guidance on the most suitable grants for your situation.
  • Use trusted installers: Ensure any work is carried out by qualified and certified installers.

Making your home a haven of efficiency

By taking advantage of available energy efficiency grants, you can transform your home into a haven of warmth, comfort, and cost savings. Don’t let those energy bills weigh you down – start exploring your options today and take the first step towards a greener, more affordable future!
