Air Source Heat Pumps Designed For Real Living
Design, supply and professional installation of Air Source Heat Pumps, underfloor heating and integrated cooling systems for residential and development projects across the UK.
Air Source Heat Pumps Designed Properly
Installed Professionally Across the UK
Since 2015, Flint Energy has designed and installed Air Source Heat Pump (ASHP) systems across residential and development projects throughout the UK.
We don’t retrofit heat pumps into unsuitable systems. We design heating and cooling around building performance — ensuring systems are correctly sized, properly integrated and built to deliver reliable comfort year-round.
By combining accurate heat loss calculations, appropriate emitters and intelligent control strategies, we create systems that are efficient, compliant and commercially sound.
Brands We Work With
We partner with trusted, industry-leading manufacturers to ensure every heat pump and underfloor heating system delivers reliable, long-term performance. Our brand selection is based on efficiency, build quality, technical support and proven results in UK properties.
We design, supply and install heat pump and heating systems that deliver efficient performance, consistent comfort and long-term reliability.

// Why Choose Flint For Your Heat Pump Installation
Heat Pump Performance Starts with Proper Design
A heat pump will only perform well if the whole heating system is designed correctly.
That means getting the fundamentals right:
✔ Detailed room-by-room heat loss calculations
✔ Correct system sizing
✔ Low-temperature heating design
✔ Radiator or underfloor heating suitability
✔ Smart controls and zoning
When designed properly from the outset, your system runs efficiently, keeps spaces consistently comfortable and avoids unexpected running costs.
We don’t just install heat pumps - we design systems that work..
Who We Design & Install Heat Pumps For
-
Heat Pumps for Developers
We design and install air source (ASHP) and ground source (GSHP) heat pump systems for residential and mixed-use developments.
✔ Improve SAP calculations
✔ Strengthen EPC ratings
✔ Support Part L compliance
✔ Reduce carbon emissions across the scheme
✔ Avoid future retrofit riskWhen designed early, system sizing, emitters and plant space are optimised - improving performance while keeping costs controlled.
-
Heat Pumps for Commercial & Industrial Buildings
We deliver heat pump solutions tailored for commercial developers, consultants and building owners, that provide:
✔ Lower long-term operational costs
✔ Reduced exposure to fossil fuel volatility
✔ Improved ESG and Net Zero performance
✔ Future-proofed compliance with tightening regulations
✔ Integration with solar and smart controlsWe design around real building loads, ensuring systems are correctly specified - not oversized, inefficient or compliance-led only.
-
Heat Pumps & Underfloor Heating for Private Homes
We provide clear, practical guidance on:
✔ Air source suitability
✔ Ground source feasibility (space permitting)
✔ Correct system sizing
✔ Radiator / underfloor compatibility
✔ Expected running costs
✔ Available grants and incentives
✔ Integration with solar PV and EV chargingHomeowners choose Flint because we focus on long-term comfort, efficiency and real-world performance - not just ticking boxes.
// Why Work With Us
Heat Pumps Work Best with the Right Emitters
A heat pump is only as effective as the system it delivers heat into. That’s why we prioritise low-temperature underfloor heating systems wherever suitable.
Underfloor heating allows heat pumps to run more efficiently than traditional radiators - improving performance while reducing running costs.
Where appropriate, we design:
✔ Full underfloor heating systems
✔ Zoned layouts for better control
✔ Cooling through floor loops where suitable
✔ Hybrid solutions for retrofit projects
The result is greater comfort, lower energy use and -on new developments - stronger support for Part O overheating compliance.
Certified, Protected & Installed to the Highest Standards
Our heat pump and underfloor heating systems are installed by qualified engineers and backed by recognised industry accreditations:
Flint Energy are proud to be fully accredited and registered with leading UK renewable energy and electrical bodies.

-
Yes. Modern Air Source Heat Pumps are designed for UK climates. Correct system sizing and emitter design ensure reliable winter performance.
-
Possibly. Radiators may need resizing depending on heat loss calculations and system design. We assess this before installation.
-
When designed properly, heat pumps are highly efficient. Running costs depend on insulation levels, electricity tariffs and usage patterns.Item description
-
Modern systems meet UK noise regulations. Correct placement and specification minimise disruption.
-
Yes. Many systems can provide cooling via underfloor loops or fan coil units when designed accordingly.
