Better design. Better comfort. Better performance.
Choosing a heat pump installer is about more than finding someone who can fit the equipment. The quality of the design, sizing and setup has a major impact on how well the system performs over time.
At Sunlite Group, we’re proud to be Heat Geek-approved installers. That means our team has undergone advanced training focused on efficient system design, low-temperature heating, heat loss calculations and overall performance optimisation. We use that knowledge to help homeowners move to a heating system that is comfortable, efficient and built around the property.
Whether you’re replacing an ageing boiler, planning a renovation or looking for a more future-ready heating solution, we can help you understand whether an air source heat pump is right for your home.
What does Heat Geek-accredited mean?
Heat Geek is a specialist heating training and accreditation platform focused on raising the standard of system design and installation. Their approach goes beyond simply fitting a unit. It centres on designing heating systems properly so they can run efficiently, deliver steady comfort and avoid the common issues caused by poor sizing or setup.
For homeowners, that means working with an installer who understands the details that affect long-term performance, including:
- Heat loss calculations for each property
- Correct system sizing
- Lower flow temperature design
- Smart controls and zoning
- Balanced heat distribution across the home
Why it matters for your heat pump installation
The performance of a heat pump depends on far more than the unit itself. Without the right design, even the best equipment can struggle to deliver the comfort and efficiency homeowners expect.
Correct sizing, suitable emitters, optimised flow temperatures and careful system design all make a meaningful difference to how well a heat pump performs over time. Getting those details right helps create a system that runs efficiently, feels comfortable and works as it should day to day.
At Sunlite Group, our focus is on designing heating systems that work in the real world — giving homeowners greater confidence in the performance, reliability and long-term value of their investment.
Why choose Sunlite Group as your Heat Geek installer
Choosing the right installer is about more than finding someone to fit the equipment. It is about working with a team that understands how to design a system properly, so it performs efficiently and delivers reliable comfort for the long term.
A tailore approach to each home
No two homes have the same heat demand. We assess the property, heating habits and current setup before recommending the right solution.
Heat loss calculations
We assess how much heat each room actually needs so the system is sized correctly.
Better system efficiency
Efficient design helps a heat pump run at lower temperatures, improving comfort and reducing wasted energy.
Emitter suitability
We review whether your existing radiators or underfloor heating are appropriate, and where upgrades may improve efficiency.
Clear, honest advice
We’ll help you understand suitability, likely upgrades, running costs and available funding without overcomplicating the process.
Flow temperature planning
Lower flow temperatures are a key part of efficient heat pump performance, and proper design helps make that possible.
One trusted team
From initial survey through to installation and aftercare, you deal with one experienced local team.
Controls and zoning
Where suitable, we can recommend smart controls and zoning strategies to improve comfort and reduce waste.
Is your home suitable for a heat pump?
An air source heat pump can be a great option for many homes, but suitability depends on more than the type of property alone. Insulation, heat demand, emitter size and available indoor space all play an important role in how well the system will perform.
That is why we take a design-led approach from the outset. At Sunlite Group, we assess your home carefully and provide straightforward advice on whether a heat pump is the right solution for your property and what, if any, upgrades may be needed.
We can help you understand:
- Whether your existing setup is suitable
- Whether larger or additional radiators may be required
- Whether a hot water cylinder is needed
- What funding may be available through the Boiler Upgrade Scheme
Heat pumps without the guesswork
Moving to a heat pump does not need to be complicated. With the right installer, the process should feel clear, well-managed and built around your home.
At Sunlite Group, we take a practical, design-led approach to every installation. From your initial survey to final setup, we focus on smart system design, a straightforward process and minimal disruption wherever possible.
The result is a heat pump system designed for efficient performance, reliable comfort and confidence at every stage of the journey.

Frequently asked questions
What is a Geat Geek accredited installer?
A Heat Geek accredited installer is a heating engineer who has completed advanced training in heat pump system design and performance. This includes areas such as heat loss calculations, flow temperature optimisation and designing systems that deliver efficient, reliable heating for the home.
Why is Heat Geek accreditation important?
Heat Geek accreditation is important because it shows an installer has been trained to look beyond simply fitting the equipment. It reflects a deeper understanding of how the whole heating system should be designed and set up to improve comfort, efficiency and long-term performance.
Are Sunlite Group Heat Geek approved?
Yes, Sunlite Group is proud to be a Heat Geek approved installer. This reflects our commitment to high standards in heat pump design, installation and overall system performance.
Can a heat pump replace my boiler?
In many homes, yes. An air source heat pump can provide the heating and hot water a property needs, as long as the system is properly designed for the home. Suitability will depend on factors such as insulation levels, heat demand and the existing heating setup.
Is funding available for heat pump installation?
Yes, funding may be available through the Boiler Upgrade Scheme. Eligible homeowners can currently access a grant of up to £7,500 towards the cost of an air source heat pump installation, helping to make the switch more affordable.
Do I need larger radiators for a heat pump?
Not always. In some homes, existing radiators may be suitable, while others may need larger or additional radiators to help the system run efficiently at lower flow temperatures. We assess this as part of the design process and advise on any upgrades needed.
