About Adlår Castra

Adlår Castra does one thing - and does it properly. Most companies install heat pumps alongside solar, batteries, and everything else. We don’t because we don’t need to.

We are the UK’s only specialist in dual heat pump architecture. Because we manufacture and install our own systems, we control every detail - from heat loss calculations and system design to grant management, installation, and commissioning.

Your system remains efficient, reliable, and fully supported by our expert team for 15+ years. Our Warmth Guarantee means if your heating or hot water doesn’t perform as designed, we’ll come back and fix it - at no extra cost - until it does.

The Smarter, Greener Way to Heat Your Home
Adlår Castra’s dual heat pump system is designed to deliver unmatched efficiency and comfort, ensuring your home is kept consistently warm and your bills low. Unlike traditional boilers and single air source heat pumps, there’s no compromise on heating or hot water with Adlår.

With a higher SCOP (Seasonal Coefficient of Performance) than other leading systems, we’re one of the most energy-efficient options on the market, and with the £7,500 Boiler Upgrade Scheme grant, we’re one of the most affordable options too.

Cost, Carbon and Comfort
By switching from a traditional boiler system to Adlår Castra’s dual heat pump, you’re actively contributing to a cleaner, greener UK. What’s more, our advanced technology can cut your energy bills by up to 40% per year, helping you save money as well as the planet.

Whether you’re motivated by cost, carbon, or comfort, we’re here to make the process clear, quick, and worthwhile.
