Expert Fault Finding & Advanced Diagnostics
Manufacturer Approved. Multi-Brand Experts.
We are proud to be Registered & Accredited Installers for the UK’s leading heating brands. While we specialise in providing extended warranties for Ideal, Vaillant, Glow-worm, and Worcester Bosch, our three-generation diagnostic heritage means we can service and fault-find any make or model of boiler or electrical system.
Why Choose WTS?
The "X-Ray" Advantage: I single-handedly built my own home from the ground up. I don’t just see a boiler; I understand the structure, the pipes behind the plaster, and the wiring beneath the floors.
3rd Generation Heritage: Expertise is in the DNA. My approach was shaped by a father who was both a Gas Engineer/electrician and a former Electronic Design Engineer.
Beyond the Pipes: We understand the circuitry and communication protocols (Nest/Hive/Tado) that modern boilers rely on.
Specialist Services
Advanced Diagnostics: We use precision tools to test sensors and boards—only replacing what is truly broken.
Complex System Wiring: Master-level understanding of S-Plan, Y-Plan, and Smart Home wiring conflicts.
Intermittent Lockouts: We use logical testing sequences to catch the "ghost" failures other tradesmen miss.
The "No-Guesswork" Guarantee
We only fit parts that are electrically or hydraulically PROVEN to be faulty.
Root Cause Analysis: If a pump fails, we find out why (sludge, wiring, etc.) to protect your new part.
Evidence-Based: Every recommendation is backed by multi-meter testing and system analysis.
Transparent: We explain the technical link between faults before we start the work.
