JLS Plumbing & Mechanical is a Gas Safe registered, Zurich insured plumbing, electrical and mechanical company serving every London borough. For over a decade we've delivered domestic and commercial work to one consistent standard — from a single tap repair to a full bathroom refit, fuse board upgrade or boiler installation.
We go above and beyond on every job. Transparent pricing, clean working practices, certified trade engineers and a 12-month workmanship guarantee on every job we complete.
By UK law, all gas engineers working on gas appliances must be on the Gas Safe Register. Using anyone else risks serious injury, carbon monoxide leaks, and invalid home insurance. JLS engineers are Gas Safe registered — every gas job is certified, documented and signed off properly.
Most London homes and businesses are losing money to silent leaks and untracked usage. JLS installs Smart Water Meters that show you, in real time, what's actually being used — so you can spot leaks early, monitor consumption, and cut bills.
See exactly what you'll pay before we book the job in. Fair rates, clearly published — for everything from a tap washer to a full bathroom refit.
A clear, structured process — so you always know what's happening, what it costs, and when it'll be done.
Phone, WhatsApp or contact form — we listen, ask the right questions and understand your specific plumbing, gas or electrical needs.
A certified engineer attends to carry out a detailed assessment of your system — diagnosis, scope, materials and timing.

Job delivered on time and within budget. Clean working practices, tested, signed off, certified — 12-month workmanship guarantee included.
