What factors affect the cost of solar thermal heating installation in the UK?

When working out the cost of a solar thermal heating installation, here are the main variables that will impact the amount you pay for your new system:

• Energy needed – The more energy you need to produce, the higher your solar thermal system will cost
• Number of panels – The more panels you require, the more you’ll pay
• Roof direction – If your roof faces north, you’ll need more panels to produce the same amount of power, increasing the cost
• Battery – Installing a solar battery allows you to collect excess solar energy to be used at nighttime and darker days but this is an additional cost
• Location – Where you live in the UK will affect how much you pay for labour

Is solar thermal heating worth it?

Solar thermal heating can be worth it if your household uses a lot of hot water. It’s most effective for:

• Homes with regular hot water demand
• Properties with south-facing roofs
• Households looking to reduce energy bills and emissions

It's worth noting, savings depend on usage, system size, and installation quality.

What’s involved in solar thermal heating installation?

Installation is a complex, specialist job. That said, it’s usually completed within a few days and includes:

• An initial site visit to assess the roof space and orientation
• Installing solar collectors on the roof
• Fitting or upgrading a hot water cylinder
• Connecting the system to existing plumbing and boiler
• Testing and commissioning the system

A certified solar thermal installer will also explain how to use and maintain the system.

Can solar thermal work with my existing boiler?

Yes. Solar thermal systems are designed to work alongside existing boilers.

The boiler acts as a backup, heating water when solar energy isn’t sufficient. This makes solar thermal a practical upgrade rather than a full replacement system.
