What a fitted boiler from LMB includes

Installations start from £1,900 fitted. That price includes the boiler, standard pipework and valves, a standard flue, filling loop, system fill and commissioning, removal of your old boiler and packaging, your Gas Safe certificate and the Building Regulations notification. Anything not included is listed separately on your quote before you pay a penny, so the number you accept is the number you pay.

LMB is a Baxi Approved Installer and also fits Worcester Bosch, Ideal and Vaillant. Manufacturer warranties run up to 12 years depending on the boiler you choose, registered for you on installation day. Lloyd is City & Guilds qualified and Gas Safe registered, and LMB is domestic gas only, mains or LPG, no commercial plant, and he will say so honestly if your job falls outside that.

From quote to warm house

The process is deliberately short. Get your fixed price online in about 90 seconds, with no sales visit needed for a straightforward swap. Pay the £100 deposit to lock in a date that suits you, with finance available if you would rather spread the cost. On the day, the old boiler comes out, the new one goes in, the system is filled, balanced and commissioned, and you finish with the certificate, the notification and a registered warranty. Most straight swaps are done in a single day.

Not sure what you need? The guides cover the common questions: what moves the price, combi or system boiler, and whether a heat pump makes more sense for your house.

Questions people ask

How does the 90-second fixed price work?

You answer a few questions about your home, your current boiler and your hot water use, and the quote tool prices the job from the same price list Lloyd uses in person. For a straightforward swap the price is fixed, and anything genuinely extra is itemised and agreed before installation day.

Which areas do you install in?

Pencoed and Bridgend are home ground, with Porthcawl, Maesteg, Pyle, Cowbridge and the Vale of Glamorgan covered as standard. For new boiler installations Lloyd travels the M4 corridor from Neath in the west to Cardiff and Penarth in the east. Swansea and the valleys north of the M4 are outside the patch. See the areas page for the full picture.

Which boiler brands can I choose from?

LMB is a Baxi Approved Installer and also fits Worcester Bosch, Ideal and Vaillant. Manufacturer warranties run up to 12 years depending on the model, and Lloyd registers the warranty for you on installation day.

How long does an installation take?

A like-for-like combi swap is normally one day on site, usually finished by mid afternoon. Conversions, for example heat-only to combi, can take longer, and your quote confirms the duration before you book.

Who actually does the work?

Lloyd Bargery, the owner. LMB is owner-led, so the Gas Safe registered engineer in your kitchen works to the standard those reviews were earned on, from quote to certificate.
