Gav Murray, Director of EV & Solar at Hive, discusses why the ‘golden triangle’ of solar, batteries and heat pumps is creating new opportunities for installers to deliver smarter, connected home energy systems.
As households look for ways to cut bills, improve efficiency and take more control over their energy use, installers are seeing the conversation move beyond single-product upgrades. For many customers, the first step might still be solar panels, a battery, a heat pump or smart controls. But increasingly, they are not looking at those technologies in isolation. They want to understand how each upgrade can help their home run more efficiently today, and how it can support further changes in the future.
That is where the idea of the ‘golden triangle’ comes in. Across the renewable energy sector, the phrase is used to describe the combination of solar, battery storage and heat pumps. Individually, each technology has a clear role. Together, they can help households move towards a more joined-up home energy system that is less reliant on the grid, easier to optimise and better protected from energy price volatility.
For installers, this represents both a major commercial opportunity and a serious operational challenge. A few years ago, solar panels, batteries and heat pumps were often treated as separate jobs. Increasingly, that is not how customers think. They may not be buying three technologies at once, but they are looking for a home energy system that can build over time, with each upgrade making the next one easier to understand.
The ecosystem matters more than the hardware
The real value of the golden triangle is not simply having solar, storage and a heat pump in the same home. It is what happens when those technologies are connected, optimised and working as one system.
That means thinking beyond the products themselves. Generation, storage, heating demand, tariffs and smart controls all need to work together if customers are going to see the full benefit.
The wider market is starting to make connected home energy systems easier for customers to access. The recent British Gas partnership with Sunsave is a useful signal of where this is heading. It offers home batteries with no upfront cost, installation in weeks and tariffs designed to help households store cheaper electricity and use it later.
For customers, this is about more than technology. It is about feeling less exposed to volatile energy costs, more confident in how their home is running and more in control of what they pay.
Customers want simplicity, not complexity
Most customers do not want to become energy experts. They are not interested in kilowatt-hours, inverter specifications or coefficient of performance. What they want to know is whether the system will keep their home warm, reduce their bills and work without constant intervention.
As homes become more electric, the risk is that we expose customers to too much complexity. If solar, batteries, heating, EV charging and tariffs all sit in different silos, the experience quickly becomes confusing. One app becomes five apps, one decision becomes several, and the promise of control starts to feel like another household admin task.
The sector has to move in the opposite direction. Customers should not have to optimise everything manually. The system should quietly do the hard work in the background.
Installers are becoming trusted advisers
This creates a much bigger role for installers. A solar enquiry naturally leads to storage, a heat pump installation raises questions about electricity usage and smart controls. That is how the market will scale, with customers building confidence one step at a time, and each upgrade making the next one easier to understand.
This opens up new revenue opportunities beyond initial installation including system design, servicing, controls integration and customer education. The installer becomes a trusted adviser helping households make a plan, which matters particularly with heat pumps, where customers are often cautious and want reassurance.
The skills challenge cannot be ignored
As more homes move towards golden triangle systems, installers will need a broader skillset than traditional heating or electrical work alone. It is no longer just about fitting one product well but understanding how it may need to work alongside solar, battery storage, heat pumps, smart controls and tariffs over time.
That means confidence in heat loss calculations, system design, electrical integration, product compatibility, commissioning and aftercare. The more connected the home becomes, the more important it is that each installation is designed with the wider ecosystem in mind.
This is not just a numbers issue. It is a confidence issue. Many installers are willing to upskill, but small businesses need to know demand will be sustained before investing in training, tools and time away from paid work.
That is where manufacturers, energy companies and training bodies need to step up. The technology works. The question now is whether we can make it installable, repeatable and commercially viable for the trade.
Support needs to work on site
As well as training, installers need practical support when they are on the job.
That is why we launched the Hive Installer Club as a free-to-join support programme. It provides guided setup workflows, built in diagnostics, product manuals, how-to videos and priority technical support. The aim is to help installers achieve quicker, more reliable installations with fewer callbacks and greater confidence when working with connected systems.
For independent installers and small businesses, that matters. A callback is not just inconvenient. It costs time, money and customer trust. If we want installers to recommend more joined-up low-carbon systems, we have to make those systems easier to install and easier to support.
Interoperability will decide the customer experience
The golden triangle only works if technologies communicate. When systems do not integrate, it creates frustration for customers and repeat visits for installers. Homes of the future will not be defined by single products but by how well they work together.
Ultimately, the golden triangle is about helping households build more resilient homes, with greater control over their energy use and better protection from cost volatility. But it will not be delivered by technology alone. It will depend on installers who can make complex home energy systems feel simple, trusted and worthwhile.
