How ECO4 Grants Unlock Fully Funded Solar Panels, Heat Pumps & Insulation
How ECO4 Grants Unlock Fully Funded Solar Panels, Heat Pumps & Insulation for UK Landlords, Tenants & Homeowners. In today’s climate, both literally and figuratively, UK homeowners, landlords and tenants are under pressure. Rising energy bills, ageing heating systems, inefficient homes and new regulations around energy performance are forcing a rethink. But here’s the good news: thanks to the UK Government’s ECO4 scheme, fully funded upgrades are available that can turn your property into a high-efficiency, low-carbon home. At Cucumber Eco we specialise in helping eligible parties access ECO4 grants and make smart, eco-friendly home upgrades.
The ECO4 grant scheme (Energy Company Obligation phase 4) is the latest government-backed support programme designed to improve energy efficiency in UK homes. It covers fully funded or heavily subsidised measures such as insulation, renewable heating systems and solar panel installations.
The aim is to help households reduce energy bills, cut carbon emissions and boost energy performance ratings (EPCs). What makes it especially relevant for landlords, tenants and homeowners is that many upgrades can be accessed with no upfront cost, thanks to ECO4 grants. At Cucumber Eco we guide you through the eligibility, application and installation processes.
With energy prices climbing and regulatory pressure increasing (for example landlords needing to meet minimum EPC standards), there’s never been a more urgent time to act on home energy efficiency. An ECO4 grant can help deliver:
By using an ECO4 grant, you don’t just make your home greener—you make it smarter and more cost-efficient.
The ECO4 scheme covers a wide range of energy-efficient home upgrades, and helping you decide which ones are right is where we come in. Eligible households can receive insulation measures such as loft insulation, cavity wall insulation, solid wall insulation or internal wall insulation—these help retain heat and cut energy bills. They can also benefit from heating system upgrades, including installing an air-source heat pump, upgrading or repairing an old boiler, or switching inefficient electric heating. In some cases, the scheme supports renewable energy installations such as solar panels, particularly when paired with low-carbon heating systems.
In short, the upgrades span insulation, heating and renewables, creating a holistic approach to improving your home’s energy performance.
Homeowners: If you own your home and live there, an ECO4 grant means you may qualify for substantial upgrades, insulation, solar, heat pumps, with little or no cost to you. That means lower energy bills, a more comfortable home and a better energy-performance certificate.
Landlords: For private rental property owners, improving EPC ratings is becoming essential. ECO4 grants let landlords upgrade insulation, heating systems and renewable tech at little or no cost, helping meet regulatory requirements and making the property more attractive to tenants.
Tenants: While tenants don’t always access grants directly, upgrading a rental property via ECO4 means lower running costs and better comfort. Cucumber Eco can work with landlords and tenants to deliver the upgrades and ensure benefits reach the household.
Yes—in many cases. For eligible households and properties, ECO4 grants can cover the full cost of insulation or renewables.
Eligibility depends on property type, current EPC rating (typically D-G households), whether you receive certain benefits or meet income thresholds.
Yes. Landlords can apply for ECO4 grants for rental properties provided certain criteria are met and the tenant, property or both qualify.
Savings depend on current energy use, the scale of the upgrade and energy prices. You’ll get lower heating bills, better comfort and an improved energy-performance rating.
The shift to sustainable, energy-efficient homes is no longer optional—it’s essential. By using ECO4 grants, you don’t just upgrade your home; you transform it into a low-carbon, high-performance asset. Whether you’re a homeowner, landlord or tenant, the opportunity is here—and Cucumber Eco can help you seize it.
From fully funded insulation and solar panels to efficient heating systems and improved EPC ratings, ECO4 grants make smart, eco-tech decisions accessible. Visit Cucumber Eco today at https://cucumbereco.co.uk and start the journey to a warmer, greener, more efficient home.
