Plumber in Cardiff

Owner-led plumbing and Gas Safe heating work across Cardiff and the western suburbs, from a business judged on its 5.0 review record rather than its postcode.

Cardiff has no shortage of plumbers. What it has a shortage of is plumbers you can check before you book, where the same name does the quote, the work and the follow-up. LMB Plumbing & Heating carries 207 Google reviews at a straight 5.0, all under real names, and the name running through them is Lloyd, the owner. When a city gives you endless choice, the public record is the filter that actually narrows it down.

The everyday jobs, and the bigger ones

The day-to-day list first: dripping and seized taps, leaks and weeping joints, radiator faults and cold spots, outdoor taps, hot water problems and the general pipework repairs every home needs sooner or later. Then the kitchen and bathroom side: taps, shower valves, leaking showers and toilets, and the supply and waste pipework that comes with a refit.

Where most plumbers stop, LMB keeps going. Because Lloyd is a Gas Safe registered heating engineer, the same visit can cover boiler faults, gas pipework, full central heating work and annual servicing. For a lot of Cardiff customers that is the real reason to call: one trade who handles the leaking valve today and quotes the new boiler properly when the old one is on its way out, with installations from £1,900.

Honest about coverage

Straight answer on geography: LMB is based in Pencoed, west of the city, and covers Cardiff and the Vale from there. That means the western suburbs and the Vale side, Llandaff, Radyr, Creigiau, Pentyrch and out toward the city, are the natural patch. It is the right setup for planned work and boiler installations, where being a touch out of town costs nothing and the quality of the work is what you are paying for.

Before you book anyone in Cardiff, do the two checks worth doing: read their real Google profile, not the testimonials on their own site, and if the job touches gas, look them up on the Gas Safe Register. LMB passes both in the open, with Baxi Approved Installer status behind the heating work too.

Cardiff houses, Cardiff pipework

Cardiff is two plumbing jobs in one city. The Victorian and Edwardian terraces of Canton, Roath, Grangetown and Cathays hide the usual surprises behind the walls: lead or old galvanised supply pipe, waste runs added in layers over a century, stop taps painted into place. The newer suburbs and apartments are cleaner work but the diagnosis still matters. A plumber who knows which house he is walking into before he lifts a floorboard saves you the small job that turns into a wet ceiling.

Annual service
Hired Lloyd to carry out a boiler service and outdoor tap replacement. Very punctual, polite. Even giving our dog buddy a fuss. No mess or delays.

Questions people ask

Do you actually cover Cardiff if you are based in Pencoed?

Yes, across Cardiff and the Vale, with the western suburbs and Vale side the most natural patch. Being a little out of the city is no issue for planned plumbing and boiler work, and it is reflected honestly rather than dressed up as city-centre local.

Can you handle heating and boilers, not just plumbing?

Yes. LMB is Gas Safe registered, so boiler repairs, servicing, gas pipework and full installation are covered alongside general plumbing. New boilers are fitted from £1,900 with a fixed price available online in about 90 seconds.

How do I get a price?

For plumbing and repairs, call or WhatsApp 07712 646488 with a photo of the problem and you get a straight answer before anything is booked. For a new boiler, the online quote tool gives a fixed fitted price in about 90 seconds.

How do I know the work is properly done?

Check the public record. A 5.0 rating from 207 named Google reviews, Gas Safe registration for the gas work, and Baxi Approved Installer status. All of it is verifiable before you book.
