About Sleemans
A service as much as a supply.
Sleeman & Hawken have supplied engines, generators and genuine spare parts from Teignmouth in Devon for nearly 70 years. What customers come back for isn’t just the part. It’s the person on the phone who knows exactly which part they need.
Sleemans brings that experience together with our own generator ranges and battery packs, under one name and one team.

Our story
Nearly 70 years of keeping engines running.
Engine people in a Devon harbour town, supplying customers across the UK and around the world.
Where it started
Sleemans began as a spare parts business, and parts are still at the heart of what we do. For decades, engineers, farmers, boat owners and machine builders have rung Teignmouth when they needed the right part for an engine, often one that’s no longer made.
What we do now
Today we supply new and replacement diesel engines from Hatz, Lister Petter, Rehlko and Yanmar, our own Fusion, Horizon and Quantum generator ranges, and LiFePO4 battery packs, alongside genuine parts for thirteen brands. You can buy online, or talk to someone who knows the kit.
Where it goes
From a single gasket by courier to a 20ft container of filters, we ship all over the world. Our consolidated shipping brings engines, generators and parts from different makers together into one delivery, with the export paperwork done.
How we look after you
We listen first
A serial plate, a photo or a description is enough to get started.
We get it right
Checked against manufacturer data, so the part fits first time.
We ship it carefully
Packed in Teignmouth, from a single gasket to a full container.
We stay on hand
Technical help after the sale, for as long as you run the engine.
