Energy bills across the UK have risen dramatically in recent years, leaving many Powys residents searching for ways to cut costs without sacrificing comfort. Traditional heating systems, such as old oil boilers or inefficient electric heaters, are becoming more expensive to run and maintain. A growing number of households are evaluating installing a heat pump in Powys – a smart, low-carbon alternative that can provide reliable heating while significantly reducing energy usage. Even better, under the ECO4 scheme, many homeowners in Powys may be able to have a new heat pump installed completely free of charge.
This guide explains everything you need to know: how heat pumps work, the benefits they offer, which Government grants you can apply for, and how Green Homes Group can help you secure funding and connect with trusted installers.
A heat pump is a renewable energy system that extracts heat from the air, ground, or nearby water source and transfers it into your home to provide central heating and hot water.
Instead of burning fossil fuels like a gas or oil boiler, a heat pump uses a small amount of electricity to move existing heat from outside to inside. It works a bit like a refrigerator in reverse — taking warmth from one place and releasing it into another.
There are two main types of domestic heat pumps:
Both systems can achieve impressive efficiency — for every unit of electricity used, a heat pump can deliver up to four units of heat, making it a highly cost-effective solution once installed.
Heat pumps are becoming increasingly common across Powys, particularly in rural areas where properties are often off the mains gas grid. For homes currently using oil, LPG, or electric heating, switching to a heat pump can cut heating bills dramatically while improving comfort.
They also align with the UK Government’s Net Zero strategy, which aims to reduce reliance on fossil fuels. As a result, support schemes such as ECO4 have been introduced to make renewable technologies like heat pumps accessible to more households.
For many Powys residents, this combination of energy savings, environmental impact, and financial support makes heat pumps the perfect upgrade.
Although the upfront installation cost of a heat pump can seem high, the long-term financial benefits are significant. A well-installed heat pump typically saves hundreds of pounds per year compared to older, inefficient systems.
For example, a household replacing an outdated electric heating system could see savings of £400–£700 per year, depending on usage and property size. When combined with the free funding available through ECO4, the financial case becomes even stronger — with many homes in Powys getting a new system at no personal cost.
One of the biggest advantages of heat pumps is their ability to cut carbon emissions. Because they use electricity to transfer heat instead of burning fuel, they can reduce household carbon output by up to 65% compared to an oil boiler.
In a county like Powys, known for its natural beauty and rural environment, heat pumps help preserve that environment for the future while supporting the UK’s wider sustainability goals.
Modern heat pumps provide a steady, comfortable temperature throughout the day, eliminating the sharp temperature fluctuations common with older systems. They work quietly and efficiently and require minimal servicing — usually just an annual check-up.
With optional smart heating controls, homeowners can manage heating remotely via an app, adjusting settings to match daily routines and further improve efficiency.
The air source heat pump is the most popular and widely installed option across Powys. It works by absorbing heat from the outside air and converting it into usable energy for your home’s central heating and hot water.
Installation is typically straightforward, involving an outdoor unit (similar in size to an air-conditioning unit) and an indoor component connected to your existing radiators or underfloor heating.
ASHPs are ideal for:
Ground source systems use underground pipes to extract stored heat from the soil. This method is extremely efficient as the ground maintains a consistent temperature year-round.
Although they require more space and higher initial installation effort, they deliver exceptional performance and are highly reliable. For larger rural properties in Powys with sufficient outdoor land, a GSHP can be a perfect long-term investment.
Choosing between air or ground source depends on several factors — including your home’s insulation, land availability, and energy usage. During your free home survey, Green Homes Group will assess these details and help you decide which system and funding route are most suitable under the ECO4 scheme.
The Energy Company Obligation (ECO4) is a UK Government initiative designed to improve energy efficiency in homes, reduce fuel poverty, and lower national carbon emissions.
Through ECO4, major energy companies are required to fund energy efficiency upgrades for eligible households — including free air source heat pump installations.
In Powys, this means that if you qualify, you could have:
ECO4 focuses on helping low-income or vulnerable households living in energy-inefficient properties (those with an EPC rating of D or below). It is particularly beneficial for rural areas like Powys, where many homes are older and off the gas network.
The Boiler Upgrade Scheme is another Government initiative supporting low-carbon heating. However, it works differently – it offers grants of up to £7,500 to homeowners who can pay part of the cost upfront.
While valuable, BUS is often better suited to middle-income households, whereas ECO4 remains the best route for low-income families who cannot afford the upfront expense of switching to a heat pump.
Before installing a heat pump, ensuring your home is properly insulated is crucial. The Great British Insulation Scheme (GBIS) provides support for measures such as loft insulation, cavity wall insulation, and draught-proofing.
In many cases, ECO4 and GBIS can be combined, meaning you may receive full funding for both insulation improvements and your new heat pump – maximising warmth and efficiency.
The Powys County Council supports energy efficiency through Local Authority Flexible Eligibility (LA Flex). This allows the council to approve ECO4 funding for households that do not meet standard benefit criteria but are still living in cold or inefficient homes.
Through LA Flex, even if you’re not receiving benefits, you may still qualify for ECO4 funding based on your home’s energy performance or health factors.
To qualify for ECO4 funding, you must:
ECO4 prioritises properties that are hard to heat or poorly insulated. If your home needs improvements such as wall or loft insulation before a heat pump can be installed, these upgrades are usually included as part of your ECO4 package.
This holistic approach ensures your home stays warm, efficient, and suitable for renewable heating systems.
Determining whether you qualify for ECO4 can be complex — but that’s where Green Homes Group comes in.
