How to Find a Reliable Plumber in Ireland

Finding a reliable plumber in Ireland is one of those tasks that sounds straightforward until you actually try to do it. Ring around, get a few numbers from a neighbour, post in the local Facebook group, and then wait two weeks for a call back that never comes.

The shortage of plumbers in Ireland is real. The Central Statistics Office has flagged skilled trades vacancies as one of the most persistent labour market gaps since 2020. In Dublin and the commuter belt, demand far outstrips supply. In rural counties, you may find two or three registered plumbers covering an entire county.

This guide cuts through the noise. Here is exactly how to find a plumber, what to check before you let anyone into your home, and how to make sure you are not paying over the odds.

Why it is hard to find a plumber in Ireland

Ireland trained far fewer plumbers during the years of the construction collapse (2009 to 2014). The apprenticeship pipeline shrank dramatically, and it takes four years to fully train a plumber under the SOLAS apprenticeship scheme. The result is a structural undersupply that is still working its way through the system.

At the same time, the housing boom of the 2020s dramatically increased demand. New builds require plumbing. Older homes are retrofitting for heat pumps and insulation. The number of people working from home increased bathroom usage and accelerated renovation decisions.

The practical result: a good plumber in most Irish counties is booked four to eight weeks in advance for non-emergency work. Emergency call-outs are available but at a premium.

Where to find a plumber in Ireland

Online directories

The most reliable starting point is a vetted directory like plumbersinireland.ie or Ranksy. These platforms require plumbers to demonstrate RGII registration (for gas work), valid insurance, and at minimum basic identity verification before they can receive leads.

The advantage over a Google search is that anyone can rank in Google. A vetted directory at least provides a floor on quality.

RGII directory

The Register of Gas Installers of Ireland (RGII) maintains a public directory at rgii.ie. You can search by county and verify that a plumber’s registration number is valid. This is essential for any gas work: boiler installation, gas hob fitting, or anything touching your gas supply.

RGII registration is a legal requirement for gas work. If a plumber does gas work without it, they are breaking the law. Your home insurance may be invalidated, and the work will not be certifiable.

Word of mouth

Still the most trusted source in Ireland. The problem is that the person who recommended your plumber may not have asked the right questions: were they insured? Is there a gas cert? Have they actually registered the work?

A recommendation gets you a warmer lead. It does not replace verification.

Avoid: social media group posts

Posting “anyone know a good plumber?” in a local Facebook group will generate fifteen responses. Most will be someone’s cousin or a friend of a friend. You have no idea if they are insured. You have no way to verify their qualifications. And if something goes wrong, you have no paper trail.

Use social media to gather names, then verify those names through the RGII and ask for proof of insurance.

What to check before hiring a plumber

RGII registration (gas work only)

If the job involves gas — boiler installation, gas hob, adding a gas point — your plumber must be RGII-registered. Ask for their RGII registration number and verify it at rgii.ie. Takes 60 seconds. Essential.

Public liability insurance

Every plumber working in your home should carry public liability insurance. This covers damage they cause to your property. Ask to see their certificate. A legitimate, professional plumber will have one and will not be offended that you asked.

A standard policy provides €2 million or more in coverage. If they cannot produce a certificate, do not let them in.

Written quote

Always get a written quote before work begins. Verbal agreements are enforceable in Irish law but very difficult to prove in a dispute. A written quote — even an email — creates a clear record of what was agreed.

The quote should specify: what work is being done, what parts are included, what the total price is, and what is excluded. If the plumber will not provide a written quote, that is a significant red flag.

VAT registration

If a plumber is billing you more than €600 for labour, ask to see their VAT number. Tradespeople in Ireland must register for VAT once their annual turnover exceeds €37,500. An unregistered person charging significant sums is a sign they are either underdeclaring income or very small-scale.

How to get a fair price

The most effective thing you can do to get a fair price is get three quotes. Not to find the cheapest (that is often a false economy) but to understand the range and to have leverage if one quote seems high.

Tell each plumber that you are getting multiple quotes. This is standard practice and any professional plumber expects it.

Use cost guides — like the one on this site — to understand the typical range for your type of job before anyone shows up. Walk in knowing what a standard boiler replacement costs in Ireland. It changes the dynamic of the conversation.

Never accept a verbal price given at the door. Always ask for a written quote within 24 hours. A plumber who will not commit to a price in writing is either making it up as they go or planning to overcharge.

Red flags to watch for

• No written quote. Will only give verbal prices.
• Requests full payment in cash, upfront, before work begins.
• Cannot produce RGII registration number for gas work.
• No public liability insurance certificate available.
• No company name — just a personal name and a mobile number with no business structure.
• Price drops dramatically when you push back without changing the scope of work.
• Immediately spots “additional problems” that weren’t mentioned before work started.

None of these individually guarantees a problem. All of them together should stop you hiring that person.
