WTS: Multi-Trade Expertise. One Call, One Call-Out.

Professional Gas, Electrical, and Plumbing Services across West Sussex.

At WTS (Willett Technical Service Ltd), we don’t believe in guesswork. As both a Gas Safe Registered Engineer and a Fully Qualified Electrician, I provide a seamless service for heating, power, and diagnostics. One expert, one visit, total peace of mind.

We specialize in advanced boiler fault-finding, complex heating wiring, and high-level gas diagnostics. While others might just "swap and hope," we use precision testing and fault finding to find the root cause of your system failure—saving you time, stress, and unnecessary costs.

From tracing intermittent electrical faults in S-Plan systems to Servicing and EV charger installations, we provide a high-tech approach to home infrastructure.

What We Do

  • Expert Diagnostics & Fault Finding: Stop the "parts canon." We specialize in tracing complex heating wiring and advanced boiler logic to find the root cause of failures, saving you time and unnecessary costs.

  • Domestic Gas & Heating: From "by-the-book" appliance servicing to full boiler, cooker, and hob installations. If it involves gas, we handle it with total precision.

  • Electrical Solutions: EICR safety inspections, consumer unit upgrades, EV charger installs, and those essential "small jobs" like new lights or extra sockets.

  • General Plumbing: Everything from fixing a dripping tap or a faulty toilet to managing your full bathroom renovation from start to finish.

  • Landlord Specialist: One-stop compliance with combined CP12 (Gas) and EICR (Electrical) safety checks in a single visit.

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.
