Do you unblock outside drains and sinks?

Yes — we clear blockages in sinks, showers and domestic drains using camera surveys and mechanical rodding where needed. If a deeper drain issue is found we'll explain options and provide a written quote for repairs.

Are your plumbers fully qualified and insured?

All engineers are Gas Safe registered and City & Guilds qualified. OneHeat Ltd holds CHAS accreditation and public liability insurance; we provide certificates and compliance paperwork on request.

Can you replace a shower or fit a new bathroom?

We undertake shower swaps, tray and enclosure installs, and full bathroom refits. Work includes pipework alterations, waste connections and testing to ensure everything meets current building regulations where applicable.

Do you work for landlords and provide certificates?

Yes. We work with landlords across Barnsley and surrounding towns and can issue required paperwork when plumbing works affect gas appliances or heating systems. We also carry out regular maintenance visits on request.

Trusted by customers — finance where needed

Award recognition and strong Checkatrade/MyBuilder feedback back our workmanship, and straightforward finance options make larger installs manageable.

What we cover — general domestic plumbing from everyday repairs to full bathroom installations. That includes leak detection, burst pipe repairs, replacing damaged pipework, unblocking sinks and drains, and fitting new showers, baths and sinks. We work on Victorian terraces, post‑war semis and modern new builds around Barnsley and South Yorkshire.

How we work — site visits are practical and tidy: diagnostic checks, clear photographs for hidden leaks, written quotations and a named engineer on every job. For larger installs we offer a finance calculator and staged payment plans, and we can supply landlord paperwork when installations affect gas appliances or central heating systems.
