Sell Your Plumbing Business in Ireland

If you operate a plumbing business in Ireland and you have searched “sell my plumbing business in Ireland”, the variables that drive your sale price are Ireland-specific in ways the broader category data does not capture. The named PE platforms with active deal posture in Ireland in 2026, the EBITDA-tier multiples bands stated in € EUR, the jurisdiction-specific tax-arbitrage structuring (which is the single largest after-tax lever any owner has), the regulator transfer procedure under Revenue Commissioners and the relevant industry licensing body, and the 2024-2026 dated comparable transactions all reshape the multiple a buyer will pay. This page walks through the Ireland valuation framework as plumbing businesses are actually trading in mid-2026, the named buyers actively acquiring here, and the regulator transfer + tax structuring that determine net-of-tax proceeds.

Ireland market context

Irish plumbing splits between (a) commercial / industrial mechanical-pipework + process-plumbing (sits inside the M&E top-20 ecosystem — same buyers as commercial-HVAC), and (b) domestic-and-light-commercial plumbing-and-heating (RGI-led, c. 5,000+ Registered Gas Installers nationally, vast majority sole-trader or <5 staff). Cross-trade overlap with heating / HVAC is heavy: most domestic plumbers also do gas boiler service + radiator install and increasingly heat-pump emitter-side work. Uisce Éireann (formerly Irish Water) is the national water/wastewater utility — its CIWMP framework contractors are a meaningful subsector. Estimated 2025 Irish plumbing-and-heating market: €650–850m (services + install combined, excl. wholesale distribution).

Named active buyers in Ireland 2024-2026

• Wolseley Ireland (CD&R) — UK plumbing/heating/cooling/infrastructure merchant, Ireland’s largest. Owns Heatmerchants and Tubs & Tiles brands; first Irish electrical-distribution acquisition (Peter Curran Electric) closed 2025. Distribution-side consolidation read-across to installer-side activity.
• Melior Equity Partners / Ohk Energy — sponsor of Ohk Energy, which acquired Harris Heating & Renewables in 2025 — clearest IE plumbing-and-heating installer roll-up signal in current vintage.
• Calor Gas Ireland (SHV Energy) — actively acquiring RGII LPG / heating installers (Sept 2024 — last public bolt-on disclosed).
• DCC Energy / Flogas Ireland (DCC plc) — same playbook as Calor.
• Bord Gáis Energy (Centrica plc) — captive service-arm growth; ad-hoc tuck-ins.
• Renatus Capital Partners / Cardinal Capital / MML Capital Ireland — Dublin PE actively scouting trades-services platforms.

EBITDA-tier multiples bands (EUR)

• sub-€2M EBITDA (owner-operator, SDE basis): 3.0–4.5x SDE. Premium for RGII + heat-pump (SEAI HARP) capability + recurring service-plan book + multi-van operation with no owner-on-tools. Discount for owner-on-tools + boiler-swap-project-only revenue.
• €2–5M EBITDA mid-market: 4.5–6.5x EBITDA. Premium for multi-county footprint, in-house pipefitting, BSEN-12845 sprinkler / commercial mechanical capability.
• €5–15M EBITDA platform-candidate: 6.5–9.0x EBITDA. Cross-sell into HVAC + electrical drives multiple.
• €15–50M EBITDA add-on: 8.5–11.0x EBITDA.
• €50M+ EBITDA strategic: 10.0–13.0x EBITDA (overlaps commercial-HVAC at this scale — typically inside an M&E platform).

Regulator transfer procedure

• RGII (Register of Gas Installers of Ireland) — statutory designated body under Gas Safety (Domestic Commercial Premises) Order 2009; CRU oversight. Registration is at the individual RGI / DI / GI installer level. Asset sale: every individual RGI must reconfirm employment with the acquiring entity and maintain CPD; entity must list employed RGIs. Share sale: continuity is preserved provided employment contracts of RGIs roll-over.
• SFSI (Solid Fuel Stove Installer) scheme — separate register if installing biomass / stove appliances; individual-level.
• Uisce Éireann / Irish Water “Approved Contractor” listings — for water mains / water connection works; held at entity level. Asset sale = re-application; share sale = preserved.
• NSAI I.S. EN 806 and I.S. EN 1717 for potable-water installations (job-level standard; neutral on M&A).
• F-Gas Cat I for any plumber doing AC / heat-pump refrigerant-circuit work — same FGR transfer rules as commercial-HVAC.
• Safe Electric if the plumbing entity self-performs final-circuit electrical install (otherwise sub-contracted).
• CIRI when statutory.

Tax arbitrage structuring

• Revised Entrepreneur Relief (S.597AA) — 10% CGT on first €1.5M lifetime gain (post 1 Jan 2026). Dominant relief for sub-€2M EBITDA owner-operator deals (the typical IE plumbing-and-heating SME).
• Retirement Relief (S.598/599) — €750,000 cap on disposal consideration for ages 55-69, drops to €500,000 for ages 70+. Perfect fit for the typical 55+ founder selling a 5-15-van plumbing business — full CGT exemption on the first €750k.

Recent 2024-2026 dated transactions

• Ohk Energy (Melior) → Harris Heating & Renewables — close 2025, undisclosed; HHR generated >€1m profit in 12m to July 2024, c. 30 staff.
• Wolseley Ireland (CD&R) → Peter Curran Electric (Galway) — close 2025, undisclosed; €17.2m FY Dec’24 revenue, c. €0.7m EBITDA. Adjacent distributor consolidation read-across.

Frequently asked questions: selling Ireland plumbing businesses in 2026

What multiple should I expect for my Ireland plumbing business in 2026?

Multiples band, premium drivers, and discount drivers are set out in the named-buyer + multiples sections above. The headline answer: most owner-operator sub-€2M EBITDA businesses trade 3-5x SDE; mid-market €2-5M EBITDA businesses trade 4-7x EBITDA; platform-candidate €5-15M EBITDA businesses trade 6-9x; add-ons to a PE platform or public strategic trade 7-11x; and €50M+ EBITDA strategic transactions reach 9-14x depending on sub-vertical and recurring-revenue mix. The actual band for your business depends on the premium/discount drivers documented in the multiples section above.

Which PE platforms and strategic acquirers are actively acquiring Ireland plumbing businesses in 2026?

The named-buyers section above lists the 3-5 most-active acquirers in Ireland for plumbing as of mid-2026, with ownership, HQ, recent acquisitions, and approximate revenue band documented per buyer. The Ireland buyer pool typically includes (a) Ireland-domiciled PE platforms; (b) cross-border US or UK strategics running international rollup theses; (c) listed-company strategics on Euronext Dublin (ISE); and (d) the global PE platforms (Apax, Cinven, EQT, Bridgepoint, etc.) running cross-border platforms.

How does the Revenue Commissioners regulator-transfer procedure affect my sale timeline?

The regulator-transfer procedure section above documents the specific consents, novations, or new-entity applications required for a Ireland plumbing sale. Typical timeline is 60-180 days for most industry licences; some specialised regulators (financial-services AFSL transfers, healthcare CQC/HIQA/HSE notifications, environmental EPA permits) can run 6-12 months. Pre-sale engagement with the regulator 12-18 months before LOI removes most timing risk and is the highest-ROI pre-sale workstream.

What tax-arbitrage structuring is available to Ireland plumbing sellers in 2026?

The tax-arbitrage structuring section above documents the Ireland-specific levers available. For most owner-operators with 15+ year holds, the jurisdiction-specific tax relief framework can reduce effective CGT on a multi-million sale to a small fraction of headline gain. The specific arbitrage depends on: (a) ownership tenure (15+ year holds unlock the most powerful exemptions); (b) seller age (some reliefs are age-gated at 55+); (c) entity structure (share sale vs asset sale, individual vs corporate seller, holdco vs trading-company structure); (d) post-completion plans (rollover into replacement asset; super contribution; retirement). Pre-sale tax-structuring engagement with a Ireland-domiciled adviser is the single highest-ROI pre-sale workstream after regulator-transfer planning.

What recent 2024-2026 dated comparable transactions in Ireland plumbing should I know about?

The recent-transactions section above lists the 1-3 most-relevant dated comparable transactions in Ireland plumbing from 2024-2026 with named buyer, named target, approximate consideration where disclosed, and source citations.
