Dealer Greenshields JCB supplied the order which includes JCB Loadall telescopic handlers, X Series tracked excavators, site dumpers, mini excavators and 3CX backhoe loaders.
The fleet will be delivered throughout 2025 to work on major national infrastructure projects.
The investment marks the latest major deal between the two family businesses, a relationship that began in 1972 when Pat Flannery founded Flannery Plant Hire with a JCB 3C backhoe loader.
Now run by sons Martin, Patrick Jnr and Paul, the company’s fleet has more than 6,500 machines.
Flannery Plant Hire MD Patrick Flannery said: “Our customers continue to be delighted with the JCB range and we will continue to invest in the finest quality, innovative equipment available.
“We are particularly interested in JCB’s development of hydrogen powered machines and we plan to take the first hydrogen 3CX from JCB.
JCB Global Major Accounts MD Steve Fox said: “We are proud of our longstanding business partnership with Flannery Plant Hire, especially as Pat Snr started the business with just a 3C backhoe. The Flannery family should be very proud of their successful and forward-thinking business.”
Greenshields JCB MD James Richardson added: “As a dealer, we have been working with Flannery Plant Hire for over three decades, which results in a deep understanding of their customers’ needs and the aftersales support required to keep their machines running smoothly.”
Wembley-based Flannery Plant Hire is set to invest £107m in kit this year with £65m of Cat machines bought earlier this year.
