FAQs

Questions Cardiff homeowners ask us.

Not seeing yours? Just call or message — Kristian will answer it himself.

Engineer at work

Are you Gas Safe registered?

+

Yes. Llandaff Heating & Plumbing is Gas Safe registered — the legal requirement in the UK for anyone working on gas appliances. The Gas Safe badge is your guarantee that the engineer working on your boiler is qualified and accountable.

How quickly can you get to me in an emergency?

+

Usually 10–30 minutes, including Sunday evenings and cold wet Friday nights. We can't promise a specific time without knowing your postcode and what's going on, but the reviews speak for themselves — fast response is the norm.

Do you give a price before turning up?

+

Yes — always. Kristian explains the cost over the phone before driving out so there are no surprises. No hidden charges, no extra fees added at the end. The price you're quoted is the price you pay.

What areas do you cover?

+

The whole of Cardiff and across South Glamorgan — Llandaff, Pontcanna, Canton, Whitchurch, Cardiff Bay, Penarth, Barry and surrounding areas. If you're not sure your postcode is covered, just ring and ask.

Do you install new boilers or only repair them?

+

Both. We supply and install new boilers from all major brands (Worcester Bosch, Vaillant, Ideal, Baxi and others), as well as repair existing ones and provide annual servicing. If your boiler is on its way out, Kristian will give you honest advice on repair vs replace.

Is there a job too small to call you about?

+

No. A leaking radiator, a new stop tap, a thermostat upgrade, a full boiler replacement — no job is too big or too small. If it's gas, heating or plumbing, give us a call.

How do I get a quote?
