We have had the pleasure of using Landex Plumbing & Heating for the last 2 years for servicing and ad hoc support of our Vaillant Air Sourced pump. They have been quick to respond, flexible to address issues and helped with diagnosing any issues with our system. I’ve been happy with their customer service and look forward to using them in the future.

Our Heating Services
Hot Water
Cylinder Services
If your current hot water cylinder is inefficient, underperforming, or in need of replacement, we can help. We install modern, energy-efficient cylinders to ensure you always have reliable access to hot water, while helping lower your energy use.
Looking to upgrade to an unvented system for better pressure and faster performance? We’ll handle the conversion with full G3 compliance, ensuring your system is safe, powerful, and future-ready. Regular cylinder servicing is also available to maintain efficiency and compliance.
Boiler & System
Conversions
We offer system-to-combi boiler conversions for homeowners who want to free up space and increase efficiency. Alongside this, we replace central heating pumps and expansion vessels, helping restore full circulation, fix pressure issues, and prevent long-term damage to your boiler and system.
Every upgrade is carried out with precision and care, keeping your heating system running smoothly and reliably.
System Components
& Controls
We replace and repair all essential components of your central heating system. From faulty thermostats and immersion heaters to worn-out valves or diverter motors, our team will quickly diagnose the issue and install new, high-quality parts where needed.
We also handle motorised valve replacements, control upgrades, and immersion heater repairs, ensuring your system operates efficiently and responds properly to your needs.
System Flushing
Services
A build-up of sludge or scale in your heating system can cause cold spots, noisy pipes, and reduced boiler efficiency. We offer system flushing services to remove debris from radiators and pipework, improving circulation and performance while extending the life of your boiler.
If your heating feels slow to start or uneven around the house, it could be time to give your system a clean from the inside out.
Radiator & Towel
Rail Installations
We supply and install a wide range of modern, efficient radiators and towel rails, suitable for every room in your home. Whether you’re updating your look or planning a full heating overhaul, we offer styles to match – from classic white and chrome to matte black and brushed brass finishes.
All installations are carried out with care, ensuring maximum heat output, clean pipework, and a tidy finish.
Underfloor
Heating
We install and maintain both wet (water-based) and electric underfloor heating systems – perfect for creating even, comfortable warmth in kitchens, bathrooms, extensions, and open-plan living spaces.
Our engineers are trained in installation, troubleshooting, and repair, so whether you’re adding UFH to a new room or need help diagnosing a problem with an existing system, we’ve got you covered.
