The wider county includes towns such as Newcastle West, Rathkeale and Kilmallock where gas installation demand varies. Rural Limerick relies more on oil and LPG, particularly west and south of the city. Installers based in Limerick city typically carry a strong book of boiler installation and service work, while county-based installers see more mixed fuel work.

Before you hire
Hiring a Plumber in Co. Limerick
Before booking any plumber, there are a few things worth confirming regardless of who you use.
Ask about qualifications
For the specific job. Gas work requires RGI registration. General plumbing benefits from CIRI registration, though this is voluntary rather than a legal requirement.
Get a written quote
That breaks down labour, parts and VAT separately. Call-out rates in Co. Limerick typically range from €60 to €120 per hour, boiler replacement from €1,500 to €3,500 depending on type and access, and a full bathroom installation from €4,000 to €12,000 depending on spec.
Confirm public liability insurance
Of at least €2.6 million, and ask for the certificate before work begins.
Request a Certificate of Completion
For any gas work. RGI installers are legally required to provide this, and it matters for insurance and property sales.
Gas work carried out by an unregistered person is illegal in Ireland and voids most home insurance policies. Always confirm RGI registration before any boiler or gas work goes ahead.
