The Vale of Glamorgan is awkward territory for boiler companies. The towns are spread out, the housing stock runs from Victorian terraces in Penarth to farmhouses outside Cowbridge, and the big national installers treat the whole area as an afterthought between Cardiff jobs. LMB treats it as part of the patch. Pencoed sits on the Vale’s doorstep, and Lloyd Bargery covers the county from end to end.

Covering the whole Vale

Cowbridge, Llantwit Major, Barry, Penarth, Dinas Powys, Rhoose, St Athan, Wenvoe, Ystradowen and the villages between them. If you are in the Vale and on mains gas, you are in the service area. Rural properties are quoted the same way as town ones: answer the questions online, get a fitted price, and anything unusual about the property is flagged and agreed before the job is booked.

What a new boiler costs in the Vale

Installations start from £1,900 fitted. That includes the boiler, standard pipework and valves, a standard flue, filling loop, system fill and commissioning, removal of the old boiler and packaging, your Gas Safe certificate and the Building Regulations notification. Anything not included is itemised on the quote, 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 model, registered for you on installation day. Finance options are available, and a £100 deposit reserves your slot.

An installer the Vale can verify

Trust is the real currency in an area where word travels through villages fast. LMB’s evidence is public: 197 Google reviews at a 5.0 rating, written by real customers under their own names. The same engineer who earned those reviews is the one who quotes your job, fits your boiler and answers the phone afterwards.

From quote to warm house

The process is deliberately short. Get your fixed price online in about 90 seconds. Pay the £100 deposit to lock in a date that suits you. 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 Building Regulations notification and a registered warranty. Most straight swaps are done in a single day.

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 cover rural properties outside the main Vale towns?

Yes, provided the property is on mains gas. LMB is a domestic natural gas business, so oil and LPG systems are outside scope, and Lloyd will say so honestly if that is your setup.

How far in advance do I need to book?

The online quote tool shows live availability, so you can see the real diary rather than guess. Straight swaps are usually scheduled within a couple of weeks.

Is the price the same across the Vale?

Yes. The fitted price depends on the boiler and the job, not the postcode. Cowbridge, Barry and Penarth are quoted from the same price list as Pencoed.

What if my home needs more than a standard swap?

Then the quote says so before you commit. Conversions, relocations and older systems get a clear itemised price, and genuinely complex jobs get a site visit first rather than a guess.

Can I spread the cost?

Yes, finance options are available through our finance partner, subject to a credit check.
