For UK homeowners shortlisting a heat pump in 2026, Stiebel Eltron is one option to compare alongside NIBE for cold-climate performance and Worcester Bosch for installer familiarity. All seven brands in this guide have distinct strengths and trade-offs. With energy prices still volatile and the Boiler Upgrade Scheme continuing to soften the upfront cost of switching from gas, more households than ever are comparing air source heat pump brands before requesting installer quotes. We’ve compared seven options based on efficiency, product range, UK-market credentials, and after-sales support, so you can move from browsing to a confident shortlist.
Stiebel Eltron may suit homeowners who prioritise independently validated quality and R290 refrigerant technology. Two points support that positioning: it won Best Domestic Air-to-Water Product at the 2026 National ACR & Heat Pump Awards, and its HPNext range runs on R290 (natural propane) refrigerant, which has a lower global warming potential than some conventional alternatives. For homes in colder regions or older properties needing higher flow temperatures, NIBE is another option, while Worcester Bosch may suit buyers who want the reassurance of a well-known boiler brand and an established UK installer network.
One practical note before the list: whichever brand you choose, installations using MCS-certified products can qualify for the Boiler Upgrade Scheme grant. All seven brands here supply MCS-certified equipment, so eligibility comes down to the installation meeting the scheme’s criteria. Confirm current grant amounts with an MCS-certified installer, as figures are reviewed periodically. If you’re still weighing whether the technology suits your home at all, the BBC’s explainer on what heat pumps are and how much they cost is a useful, neutral starting point.

How We Ranked These
We aimed to separate genuine buying credentials from marketing gloss. That means each brand was assessed against a consistent set of criteria rather than headline claims alone.
UK Availability And Installer Network
Every brand here is available to UK homeowners through UK-based installers, and network size mattered. A technically excellent product is worthless if you cannot find a trained engineer to fit and service it locally.
Independent Awards, Certifications And MCS Baseline
We treated MCS certification as a non-negotiable baseline – it is required for Boiler Upgrade Scheme eligibility, and all seven brands supply MCS-certified products. Beyond that, we gave weight to independent third-party validation, such as industry awards and recognised sustainability credentials, which carry more evidential value than a brand’s own marketing claims.
Product Range And Efficiency
We looked at how broad each brand’s model range is (outputs, monobloc versus split, air source versus ground source) and at real-world efficiency. A key measure here is the COP rating – the coefficient of performance, which describes how much heat a unit produces per unit of electricity it consumes. A COP of around 3 to 4 is typical for a well-matched air source system.
After-Sales Support And Longevity
Heat pumps typically last 15 to 20 years or more, so parts availability, warranty backing, and service infrastructure were weighted heavily. Manufacturer-led installer training also counted, as it correlates strongly with installation quality – the single biggest determinant of whether a system performs to its rated efficiency.
The 7 Best Heat Pump Brands in the UK for 2026
The right heat pump brand depends on your property type, budget, and priorities. An older stone cottage in the Highlands has very different needs from a new-build flat in Bristol. The list below covers seven options, and each entry carries a “best for” tag so you can jump straight to the heat pump brands UK buyers in your situation may want to compare. The numbering provides a comparison order rather than a universal claim that one brand is best for every property.
#1. Stiebel Eltron – Best For Independently Validated Quality And R290 Refrigerant Technology
An option for homeowners who want engineering pedigree backed by independent recognition.
Founded in 1924, Stiebel Eltron brings over a century of German engineering heritage to the UK market and offers both air source and ground source heat pumps. As reviewed in September 2026, the company states that it has manufactured more than 500,000 heat pumps. External validation includes its 2026 Best Domestic Air-to-Water Product award at the National ACR & Heat Pump Awards and Ethical Consumer Best Buy status, which relates to sustainability and ethical criteria rather than heat-pump performance alone.
Its HPNext range uses R290 (natural propane) refrigerant. R290 has a lower global warming potential than some conventional refrigerants used across the sector. The brand also runs the Heat Pump Pass programme, offering free installer training.
Cost needs to be assessed on the individual project. Heat-pump pricing depends on the selected unit, system design and installation requirements, so homeowners should compare like-for-like installer quotes.
Pros:
- 2026 National ACR & Heat Pump Awards winner – Best Domestic Air-to-Water Product (independent validation)
- Ethical Consumer Best Buy status – ethical and sustainability recognition
- HPNext range on R290 refrigerant – lower global warming potential
- Both air source and ground source options for UK homes
- Manufacturer-backed installer training via Heat Pump Pass
Cons:
- Project cost depends on the selected model, system design and installer quote
- Installer choice and local availability need to be checked
- System sizing and emitter compatibility require a property-specific assessment
- Not every home will suit every model in the range
Who it’s best for: Homeowners who value independently verified quality, ethical credentials, and R290 refrigerant technology, and who are prepared to compare project-specific system designs and installer quotes.
#2. NIBE – Best For Cold-Weather Performance And Homes Requiring Higher Flow Temperatures
A specialist option for properties where winter temperatures can drop below freezing and higher flow temperatures may matter.
Swedish manufacturer NIBE has built its reputation in Scandinavian climates, which gives it a credible track record where it matters most for many UK buyers: performance when the outdoor temperature drops below freezing. It offers both air source and ground source ranges, backed by an established UK distribution and installer network.
Its higher flow temperature models are relevant to parts of the British housing stock where existing radiators were designed around hotter boiler systems. In some properties, higher flow temperatures can reduce the scale of radiator changes needed, but that depends on the home’s heat-loss calculation and system design.
The trade-off is that buyers should check local installer availability and make sure the controls and proposed system setup suit their preferences.
Pros:
- Scandinavian-market heritage and cold-climate product focus
- Higher flow temperature models suit existing radiator systems
- Comprehensive ground source range alongside air source
- Established UK presence and trained installer network
- Long specialist history in heat pump technology
Cons:
- Project pricing depends on the selected model and installation design
- Installer availability varies by region
- Controls and setup should be reviewed with the installer
- Higher-flow-temperature operation still needs correct system sizing
Who it’s best for: Homeowners in Scotland, northern England, or any property facing sub-zero winters, especially where keeping existing radiators is a priority.
#3. Worcester Bosch – Best For Homeowners Switching From Gas Who Want A Trusted Boiler-Brand Name
The reassuring option for buyers who want the “call my usual heating engineer” experience they had with their boiler.
Worcester Bosch enters the heat pump market on the back of decades as a UK boiler-market leader, and that legacy comes with an established UK installer network. For nervous switchers, the ability to find a familiar, trained local engineer can be important. Its current UK heat pump range is centred on air-to-water Compress models; Greenstore ground source products appear under the manufacturer’s discontinued products listing.
The brand also brings aftermarket parts availability and service infrastructure. As the government pushes to make heat pumps standard in new homes, as reported by the BBC’s coverage of the UK’s green tech drive for heat pumps and plug-in solar, an established support network may appeal to homeowners who value familiar service routes.
Its current UK offering is centred on air-to-water heat pumps, so buyers seeking a current ground-source product will need to look beyond the Compress range.
Pros:
- Established UK installer network
- High consumer trust built over decades in the boiler market
- Current UK range centred on air-to-water heat pumps
- Strong aftermarket parts and service infrastructure
- Familiar reassurance for buyers moving away from gas
Cons:
- Current UK range is centred on air-to-water models
- Ground-source products appear under discontinued listings
- Project pricing varies by model and installer quote
- Buyers should confirm local support for the selected Compress model
Who it’s best for: Homeowners switching from a gas boiler who prioritise brand familiarity and the ease of finding a trusted local engineer.
#4. Panasonic – Best For A Broad Air-To-Water Model Range
An option for buyers who want a broad Aquarea range across different property sizes.
Panasonic’s Aquarea air-to-water range is one of its strongest assets, spanning a wide span of outputs from small flats to large family homes, in both monobloc and split configurations. That flexibility makes it easy to match a unit to a property rather than compromising on sizing – and correct sizing is one of the most important factors in real-world efficiency.
Panasonic publishes model-specific efficiency data across the Aquarea range, and its broad product family gives installers several sizing choices. As a large multinational, it also maintains established product support channels.
Buyers still need to confirm local installer support and the exact control features included with the selected model.
Pros:
- Broad Aquarea output range and configuration flexibility
- Model-specific efficiency data across the Aquarea range
- Established air-to-water product family
- Widely available through UK installers
- Backed by a large multinational’s support commitment
Cons:
- Heat-pump products sit within a wider product portfolio
- Local installer support should be checked
- Limited ground source options
- Control features vary by selected model
Who it’s best for: Buyers who want a broad air-to-water range and want to match a specific model to their property.
#5. Samsung – Best For Buyers Who Want Integrated Smart Controls
A smart-control-focused option for well-insulated homes.
Samsung’s EHS (Eco Heating System) range includes SmartThings integration for remote monitoring and scheduling on compatible systems. The current UK range includes both R32 and R290 air-to-water heat pump options, with monobloc and split products represented across the wider EHS line-up.
The appeal is clearest for tech-savvy buyers already inside the Samsung ecosystem. Samsung is widely known for consumer electronics as well as climate products, so buyers should check the local heat-pump installer and service support available for the exact system they are considering. Ground source options are not part of the EHS air-to-water range described here.
Pros:
- SmartThings app control and energy monitoring included
- R32 and R290 options in the current UK EHS range
- Straightforward monobloc installation

- SmartThings compatibility for existing Samsung ecosystem users
Cons:
- Brand association is electronics, not heating
- Heat-pump range sits within a broader consumer-electronics brand
- Local installer and service availability should be checked
- No ground source options
Who it’s best for: Owners of newer, well-insulated homes who want app-based control and a choice of current air-source heat pump options.
#6. LG – Best For Smart-Home Integration And Residential Renovations
An option for renovation projects that want the heating system woven into a wider smart-home setup.
LG’s Therma V range brings its ThinQ smart platform to heating, offering detailed real-time energy monitoring. Its monobloc models are designed for residential heating applications, including properties where outdoor-unit siting and monitoring matter.
LG is a consumer-tech brand with heat-pump products in its Therma V range. Ground source is not offered, so buyers looking for that technology will need another manufacturer. Local installer support and the exact smart-control features should be checked for the selected model.
Pros:
- ThinQ platform for detailed real-time energy monitoring

- Smart features may not matter to every buyer
Who it’s best for: Buyers undertaking a renovation who want integration between heating and a wider smart-home system.
#7. Kensa – Best For Ground Source Heat Pumps And Larger Or Rural Properties
A specialist option if your property suits ground source rather than air source.
Kensa is a UK-based manufacturer focused exclusively on ground source heat pump systems, giving it specialist expertise in that technology. Its compact ground source units suit a range of property types, and it has a strong record in both individual homes and communal heat network projects. A ground source system draws heat from the relatively stable temperature of the earth via ground loops or boreholes – the principle is explained well in this overview of ground source heat pumps – and is particularly relevant where a site can accommodate ground loops or boreholes.
Being UK-manufactured, Kensa also appeals to buyers who prioritise a domestic supply chain. The honest limitations are structural: ground source needs sufficient land or borehole access, the upfront installation cost is higher than air source, and Kensa offers no air source alternative if your plans change.
Pros:
- Specialist focus on ground source heat pump systems
- UK manufacturer supporting a domestic supply chain
- Ground-source systems draw on relatively stable ground temperatures
- Compact unit designs for varied property types
- Strong record in individual and communal installations
Cons:
- Requires land for ground loops or access for borehole drilling
- Higher upfront installation cost than air source
- No air source options for buyers wanting flexibility
- Installer availability should be checked locally
Who it’s best for: Rural homeowners, those with larger gardens, or anyone whose property is suitable for ground source and who can accommodate ground loops or boreholes.
Frequently Asked Questions
Should I Prioritise Efficiency Or Brand Name When Comparing Heat Pump Brands In The UK?
Prioritise a correctly sized, efficiently installed system over a familiar logo. The most important factors are MCS certification, a good COP rating for your climate, a strong local installer network, and solid after-sales support. A well-known brand fitted poorly will always underperform a lesser-known one fitted expertly.
Which Heat Pump Brand Is Considered The Best In 2026?
There is no single best heat-pump brand for every UK home. Stiebel Eltron is one option for buyers who value its 2026 Best Domestic Air-to-Water Product award and R290 HPNext range; NIBE may suit colder-climate or higher-flow-temperature needs, Worcester Bosch buyers who value a familiar heating brand and established UK support, and Kensa properties suited to ground source.
Does The Boiler Upgrade Scheme Apply To All The Brands On This List?
The Boiler Upgrade Scheme grant supports qualifying heat pump installations that use MCS-certified products, and every brand featured here supplies MCS-certified equipment. Eligibility ultimately depends on the installation meeting the scheme’s conditions rather than the brand alone, so confirm current grant amounts and criteria with an MCS-certified installer before committing.
Should I Choose An Air Source Or A Ground Source Heat Pump?
An air source heat pump absorbs heat from outdoor air and is cheaper and simpler to install, which suits the majority of UK homes. A ground source heat pump draws heat from the earth, costs more upfront, but usually delivers lower running costs long term – making it worth considering for larger or rural properties with the land for ground loops or boreholes.
Are Heat Pumps Worth It For UK Homes In 2026?
For most well-insulated or improvable UK homes, yes. Heat pumps typically produce three to four times more heat energy than the electricity they use, last 15 to 20 years or more, and can qualify for a Boiler Upgrade Scheme grant. The key is a professional heat loss calculation before you buy, so the system is sized correctly for your property.
Which Brand Fits Your Scenario
The heat pump brands UK homeowners compare in 2026 should be matched to the property rather than treated as a single universal ranking. If you want independently validated quality, ethical credentials, and R290 refrigerant technology, Stiebel Eltron is one option to consider. If you live somewhere cold or need higher flow temperatures to keep your existing radiators, NIBE may be relevant. Switching from gas and wanting a familiar heating name with an established UK support network? Worcester Bosch. Looking for a broad Aquarea range? Panasonic. Wanting smart controls and a choice of R32 and R290 air-source options? Samsung. Planning a renovation with smart-home integration? LG. And if your property suits ground source, Kensa is a specialist option.
Whichever scenario is yours, start with a professional heat loss calculation, insist on MCS-certified products and installers to keep your Boiler Upgrade Scheme options open, and get more than one quote. As the UK’s renewable heating transition accelerates through 2026 and beyond, a well-chosen, well-installed heat pump remains one of the most durable investments a homeowner can make.
