What we do?

At Stamford Radiators, we specialise in the delivery and installation of luxury cast iron radiators and the installation of air source heat pumps. We combine technical expertise with a commitment to craftsmanship, offering a truly premium service from start to finish.

We work in partnership with leading British manufacturer Castrads to deliver and install beautifully crafted cast iron radiators. With over 15 years of experience installing Castrads radiators, our team know the product inside out. Cast iron radiators are heavy and often require specialist handling — that’s why we offer a Premium Delivery & Installation service.

DELIVERY

Unlike standard kerbside deliveries, we’ll bring your radiators into your home, place them in position, expertly join larger sections if required, and take away all packaging and pallets — leaving everything clean, tidy, and ready for installation.

INSTALLATION

Experts in installing Cast Iron radiators, we’ll take care of your installation from first fix to final polish, ready for you to sit back and enjoy your new radiators.

REPAIR

Cast Iron Radiators are built without compromise, ready to last a lifetime, we can restore them to full working order with expert repairs.

AIR SOURCE HEAT PUMPS

In addition to our traditional heating expertise, we install air source heat pumps — an efficient, sustainable solution for your home. Our fully qualified team manages every stage of the process, from system design and specification through to installation and commissioning. We take care to ensure each system is tailored to your property’s unique requirements, maximising efficiency and performance while reducing your carbon footprint and long-term running costs.
