About Tom Generators
A UK diesel generator supplier built on proven engines and straight dealing.
Tom Generators supplies diesel generator sets, alternators and mobile light towers from our base in Belfast. Our range runs from compact 12 kVA Kubota sets to 2200 kVA Cummins machines for the heaviest industrial and standby duties.
We build around engines the industry trusts — John Deere, Kubota and Cummins — paired with Leroy-Somer alternators, then assemble and load-test every set in the UK before it ships. Free UK delivery and same-day shipping keep your project moving.
🇺🇦 We are proud to stand with Ukraine, and we supply generators where reliable power matters most.
