Phenna Group acquires Dublin engineering consultancy in seventh 2026 transaction

UK-based Phenna Group has acquired Dublin engineering consultancy ENX, which specialises in mechanical, electrical and plumbing design for residential developments, marking the group's seventh acquisition of 2026 and advancing continued expansion across Ireland's built environment sector through strategic bolt-on transactions.

The Business Desk reported that ENX will join Phenna's built environment division as a bolt-on to Building Energy Testers, integrating MEP design capabilities with the group's existing service portfolio. The acquisition strengthens Phenna's technical capacity across residential development projects in the Irish market.

The transaction reflects Phenna Group's active acquisition strategy throughout 2026, with the company completing seven deals in the opening months of the year. The pace of activity indicates sustained consolidation efforts across the built environment consultancy sector, with Phenna targeting complementary businesses that enhance service capabilities and geographic coverage.

ENX brings specialist expertise in mechanical, electrical and plumbing systems design for residential schemes, addressing technical requirements across housing developments from planning through construction phases. The integration with Building Energy Testers creates operational synergies within Phenna's Irish portfolio, combining energy performance assessment with MEP engineering services.

The acquisition adds to Phenna Group's established presence in Ireland, where the company has been building capabilities through targeted transactions focused on engineering, energy and sustainability consultancy services. The bolt-on approach allows retention of existing client relationships whilst providing access to group resources and wider service offerings.

Financial terms of the ENX acquisition were not disclosed. The deal continues a pattern of consolidation within Ireland's construction consultancy sector, with larger groups pursuing growth through acquisition of specialist firms serving specific technical disciplines or market segments.

Phenna Group operates across the built environment, providing consultancy services to residential, commercial and infrastructure clients throughout the UK and Ireland.
