About GenMart
Diesel generators, sold straight and priced low
GenMart is a diesel generator supplier focused on Cummins. We keep a big stock, keep prices low, and help you pick the right machine for the job.
Who we are
We sell new diesel generators for standby and prime power, from small 10 kVA sets for homes and workshops up to 1675 kVA machines for factories and data centres.
Cummins is at the heart of our range, because their engines are known for running reliably for many years. We also stock Grupel and Pramac sets for customers who want a Perkins or Yanmar engine.
Our promise is simple: the cheapest Cummins in the market, lots of stock ready to go, and honest advice on what size you actually need.
Cheapest Cummins in the market
We buy in volume and keep our margins tight, so you pay less for the same Cummins machine.
Lots in stock
We hold real generators, not just a catalogue. Most in-stock sets can be on their way within days.
UK delivery and export
We deliver across the UK and arrange export for customers abroad.
Help from start to finish
Sizing advice before you buy, then installation, commissioning and servicing after.
