About us

A family firm, not a franchise

We are based in Swiss Valley, Llanelli, and we work across Carmarthenshire and Swansea. When you ring, you get the people who will be in your house — not a booking agent selling your job on to whoever is nearest.

Why we set up

Because the trade has a reputation, and most of it is earned

Everybody has a story about a plumber. The one who did not turn up. The quote that doubled. The engineer who condemned a perfectly serviceable boiler and happened to have a replacement on the van. Those stories are why people are nervous before they even pick up the phone.

Scarlet exists because doing the opposite is not actually difficult. Price it before you do it. Turn up when you said. Explain what you found in words that mean something. Leave the house clean. None of that is complicated — it is just rarer than it should be.

We are a family business covering both trades, which matters more than it sounds. Heating and plumbing problems overlap constantly: the cold radiator that turns out to be a pressure fault, the bathroom refit that needs the boiler sizing checked first. Because we do both, nothing gets handed to a third party halfway through and nobody blames the other trade when something is not right.

We work on gas and oil, in a part of Wales where plenty of properties are off the mains entirely. And we stay local on purpose — Llanelli, Swansea, Carmarthen and the villages in between. Close enough that when you ring on a Tuesday, we can usually be there before the week is out.

How we work

Four rules we do not bend

Not a mission statement. Just the things we would want if it were our house.
  • 01

    Price it before you do it

    Nobody should find out what a job costs when the invoice arrives. Installations get a fixed written quote; repairs get diagnosed and priced before a spanner comes out.

  • 02

    Turn up when you said you would

    If we are running late you hear it from us before the slot, not after. It is a low bar and most of the trade still trips over it.

  • 03

    Say the unprofitable thing

    If a repair is the better spend than a replacement, we will tell you — even when the bigger job pays us more. That is the whole basis of getting recommended.

  • 04

    Treat the house like someone lives in it

    Because someone does. Sheets down, boots off, radio off if you are working, and everything cleared at the end of each day.

Credentials

The registrations that actually mean something

Gas work is legally restricted. Anyone can print a logo, so it is worth knowing what each of these actually certifies — and how to check it yourself.
  • Gas Safe Registered

    Gas Safe Register

    Every gas appliance we touch is worked on by an engineer on the official Gas Safe Register — the only legal register for gas work in the UK.

  • Oil Boiler Trained

    OFTEC

    Oil-fired boilers and tanks are serviced, repaired and commissioned to OFTEC standards, so your paperwork stands up for insurers and buyers.

  • Public Liability Insured

    £2m cover

    Full public liability cover on every job, domestic or landlord, so you are never carrying the risk for work in your own home.

  • Workmanship Guarantee

    12 months

    Our labour is guaranteed for 12 months, on top of the manufacturer's warranty on any parts or appliances we install.

Always check your engineer, including us

Every Gas Safe registered engineer carries an ID card with a licence number, the registration expiry and the specific types of gas work they are qualified for. Ask to see it — a genuine engineer expects you to. You can verify any card on the Gas Safe Register’s own website. It takes about thirty seconds and it is the single best protection you have.
