Cardiff has no shortage of boiler installers. What it has a shortage of is installers whose reviews you would actually want for your own house. So start there. LMB Plumbing & Heating carries 197 Google reviews at a straight 5.0, every one public, recent and verifiable. Whoever else is quoting you, put their rating next to that number and decide with your eyes open.
One engineer, not a rotating team
LMB is owner-led. Lloyd Bargery quotes the job, fits the boiler, registers the warranty and signs the certificate. In a city market dominated by firms that send whoever is free that day, having one accountable name on the whole job is rarer than it should be.
Lloyd is based in Pencoed, about 25 minutes west of Cardiff on the M4, and covers the city and its suburbs: Llandaff, Whitchurch, Radyr, Pentwyn, Ely, Rumney and the rest of the CF postcode area.
Fixed price in 90 seconds, from £1,900
The online quote tool gives you a fitted price in about 90 seconds, starting from £1,900. The price includes standard pipework and flue, system fill and commissioning, removal of the old boiler, your Gas Safe certificate and the Building Regulations notification. LMB is a Baxi Approved Installer and also fits Worcester Bosch, Ideal and Vaillant, with warranties up to 12 years depending on the model. Finance is available, and a £100 deposit reserves your installation date.
