Heat Pump Week 2025, An Interview with Mark Winn - Heatly

1. Mark, tell us about Heatly, how the product works, and what problems it solves for installers and customers alike.

Heatly is a smart digital platform and app that makes choosing and installing a heat pump faster, easier, and more reliable. It connects installers and customers in one place and guides them from the first conversation through installation, cutting time and complexity at every step.

Installers use our tools to simplify the process. Instead of manual surveys, the app quickly captures room layouts and property details. It then calculates the property’s heat loss and recommends the right heat pump, removing guesswork and ensuring accuracy.

Heatly creates 2D and 3D visuals of the system design. These diagrams show where components will go, making installation easier for installers and helping customers understand the proposal. This open approach builds customer confidence and trust, which is important for major investments.

2. Heat Pump week’s mission is to highlight the importance of heat pumps in the energy transition. Where does Heatly sit within this transition, and how will it help us, as a country, to embrace more sustainable solutions?

Heatly is designed to accelerate the decarbonisation of heating systems. A big part of that is improving communication between installers and customers — keeping everything transparent, clear, and accessible within the app so customers feel confident their system is the right fit. That clarity not only builds trust but also reduces delays, repeat visits, and unnecessary costs. 

Looking ahead, platforms like Heatly will become critical to meeting the UK’s ambition of one million heat pump installations per year from 2030. But there’s also a huge commercial opportunity here. By streamlining surveys, automating design, and giving installers tools that save time and improve accuracy, we make it easier for them to scale their businesses. For energy suppliers, distributors, and finance partners, Heatly creates a more efficient route to market and a better customer experience. So, we’re not just supporting net zero — we’re enabling growth across the entire heat pump ecosystem.

3. One of Heat Pump Week’s objectives is to ‘Encourage Adoption: Motivate both consumers and businesses to embrace heat pumps as a sustainable heating solution, thereby ensuring a greener future for all.’ How does Heatly, as a product, encourage the adoption of Heat Pumps?

One of the challenges in the heat pump market is that the installation process can feel complex and unclear. Customers often have misconceptions (like heat pumps not performing well in cold weather) and installers sometimes face inefficiencies in surveys and system design.

Our goal with Heatly was to create a solution that would make the process both more efficient for installers and more transparent for customers, while directly addressing those common barriers.

We built the platform so that installers can conduct accurate surveys and system designs. Heatly automatically shows which system should be installed, where radiators and components fit, and how to minimise heat loss. For customers, the app stores all documentation in one place and provides 2D and 3D models of their system. That visibility makes the process easier to understand and more engaging.

The impact is twofold: installers reduce costs and save time by working from precise designs, and customers gain peace of mind with a transparent, visual, and trustworthy process. This not only improves installer-customer relationships but also helps dispel myths about heat pump performance, ultimately building confidence in low-carbon heating solutions.

4. On Thursday 2nd October, Heat Pump Week will focus their messaging around ‘Installers: Bridging the Skills Gap’ We know Heatly is all about upskilling and training the next generation of installers - can you talk to us about Heatly’s part in this and how it will help fill the current skills gap to support the government's goals for net zero.

One of the barriers to scaling heat pump adoption is the skills and knowledge gap — most installers are trained on gas boilers, not low-carbon heating.

Heatly’s proprietary, patent-pending technology helps close that gap by guiding installers step-by-step through the entire process—from the first consultation and survey right through to commissioning the heat pump. 

Therefore, it is possible for existing gas engineers to transition quickly, with the same speed and confidence as fitting a boiler. It also reduces errors and costly rework, while giving consumers confidence in both the installer and the technology. 

5. Finally, one year from now, Heat Pump Week 2026, where do you see the industry, and where do you see Heatly?

The heat pump industry still faces a skills gap, with many installers trained only on gas systems. Inconsistent processes make adoption slower, and customers often delay switching due to uncertainty. I’d like to see more standardisation. 

Tools like Heatly simplify and standardise the installation process. Automated surveys and calculations reduce errors, optimise system performance, and make installations easier. This encourages more gas boiler installers to diversify into heat pumps and helps customers move confidently from old systems, including in cases where urgent or “distress” purchases are needed. 

Over the next 12 months, we aim to enable installer adoption and drive a meaningful increase in heat pump installations. By smoothing the process and giving customers confidence (even in urgent scenarios) we can accelerate low-carbon heating uptake while continuing to educate both installers and consumers on the benefits of heat pumps and district heating.
