If you’re thinking about switching to a heat pump, you probably have a few questions—and maybe even some concerns. That’s completely normal. Whether you’re wondering how they work, what they cost, or if they’ll suit your home, we’ve pulled together the most common questions we get from customers. From installation to running costs, maintenance, and more—here’s everything you need to know about heat pumps, all in one place.
Q: What is a heat pump and how does it work?
A heat pump is a low-carbon heating system that moves heat rather than generates it. In winter, it extracts heat from the outside air and brings it into your home. In summer, it can reverse the process to remove warm air—yes, a heat pump can cool your home too. It uses electricity to power this process, but it’s far more efficient than traditional electric heating.
Q: Can a heat pump cool your home?
Yes! One of the biggest benefits of a heat pump is its ability to offer both heating and cooling. In summer, it works like an air conditioner by reversing the flow of heat—removing warm air from inside and releasing it outdoors. If you’ve been wondering “can a heat pump cool your home effectively?”—the answer is a confident yes. You get a comfortable, climate-controlled space all year round.
Q: Are heat pumps suitable for UK homes and weather?
Modern air source heat pumps are designed to work efficiently even in colder climates. They’re absolutely suitable for UK homes and can operate effectively down to -15°C or lower. For most properties, especially well-insulated homes, a heat pump is more than capable of handling the British winter.
Q: What types of heat pumps are available?
There are two main types:
- Air Source Heat Pumps: The most common for residential homes. These extract heat from the outside air.
- Ground Source Heat Pumps: These extract heat from the ground via buried pipes and are typically more efficient but cost more to install.
For most homeowners, air source heat pumps offer the best balance of performance, cost, and ease of installation.
Q: How much does a heat pump cost to install?
Installation costs vary based on the size of your home, the system required, and any existing infrastructure. On average, an air source heat pump system can range from £7,000 to £13,000. However, government grants such as the Boiler Upgrade Scheme can reduce your upfront costs by up to £7,500.
Q: Are there any grants for heat pumps?
Yes. The UK government currently offers the Boiler Upgrade Scheme (BUS), which provides grants of up to £7,500 for eligible households installing an air source or ground source heat pump. This can significantly reduce the upfront cost of installation. Our team can help you check your eligibility and guide you through the application process.
Q: Are heat pumps expensive to run?
No—heat pumps are much cheaper to run than oil, LPG, or direct electric systems. They use electricity, but for every unit of electricity used, they can generate 2.5 to 4 units of heat. And remember, a heat pump can cool your home too, meaning you won’t need a separate air conditioning unit, reducing costs further.
Q: Do I need underfloor heating for a heat pump?
Not necessarily. While underfloor heating works very well with heat pumps, they can also work with radiators—especially larger or upgraded ones. At SGS Energy, we assess your current system and recommend the best setup for maximum efficiency and comfort.
Q: What about insulation—do I need to improve it?
A well-insulated home will always perform better with a heat pump. If your home is draughty or poorly insulated, you may not get the full efficiency benefits. Before installation, we’ll check your insulation and advise on any improvements to get the most from your system.
Q: How long do heat pumps last?
With proper care and maintenance, a quality heat pump can last 15–20 years or more. They’re robust, reliable, and often come with warranties of 5–7 years as standard. Regular servicing helps keep everything running smoothly for the long haul.
Q: What kind of maintenance is involved?
Heat pumps require minimal maintenance. Annual servicing is recommended to keep the system in top condition, but there’s no need for chimney cleaning, fuel deliveries, or boiler pressurising. SGS Energy provides full aftercare and servicing options for complete peace of mind.
Q: Can I combine a heat pump with solar panels?
Absolutely. Solar PV panels can power your heat pump with clean, renewable energy, making your home even more efficient and reducing electricity costs. It’s an excellent long-term solution for eco-conscious homeowners.
Q: Would a heat pump work with solar panels?
Yes—and they’re a great match. By generating your own electricity via solar PV, you can power your heat pump with zero-carbon energy. This can drastically lower your running costs and increase your home’s overall sustainability. It’s a smart investment in long-term energy independence.
Q: Do I need permission to install a heat pump?
In most cases, air source heat pumps fall under permitted development rights, meaning you usually won’t need planning permission—especially for standard installations. However, exceptions apply for listed buildings or properties in conservation areas. We’ll help you determine whether any permissions are needed for your installation.
Q: Where will a heat pump be fitted?
For air source systems, the external unit is typically installed outside your home—often at the rear or side of the property—where it can draw in air. The internal components (like a hot water cylinder or controller) are usually placed in a utility room or airing cupboard. We’ll work with you to find the most discreet and efficient layout for your property.
Q: Is a heat pump noisy?
Modern heat pumps are designed to be quiet and unobtrusive. The external unit does make a low-level humming sound while in operation—similar to an air conditioning unit—but it’s generally no louder than a kitchen fridge. We’ll make sure your system is installed in a way that minimises any impact on your household or neighbours.
Q: Will a heat pump increase the value of my home?
Increasingly, yes. As more people prioritise energy efficiency and sustainable living, homes with low-carbon systems like heat pumps are becoming more attractive on the market. Future-proofing your heating system now could give you a competitive edge if you ever decide to sell.

Switching to a heat pump is a smart choice for comfort, savings, and sustainability. Whether you want a cosy home in winter or a cooler space in summer (yes—a heat pump can cool your home!), this all-in-one system offers an energy-efficient alternative to outdated heating methods.
