Welcome to Hydraulics Online! Come on in and get to know who you could be working with if you choose to become part of our story…

Hydraulics Online was founded in 2004 by husband-and-wife team, Mark and Helen Tonks. Both shared the vision of creating a truly independent and customer-centric company – offering an alternative to the product-led distributors that were dominating the industry.

With a mechanical engineering background and a further 13 years’ hydraulic engineering experience already under his belt at that time, Mark provided the technical expertise and initial industry contacts needed to establish Hydraulics Online. Meanwhile, Helen’s earlier ‘blue-chip’ experience in financial services and strategic change management guaranteed the means to build the brand and business infrastructure that would enable their vision to flourish.

From that blank sheet of paper, Hydraulics Online has since grown to be recognised and trusted by customers in over 130 countries worldwide.

Today, this forward-thinking company is known for being a multi award-winning provider – offering a leading hydraulic design consultancy service and sourcing products from an extensive portfolio of hydraulic manufacturers. Furthermore, the UK Government’s Department for Business and Trade has recognised the brand’s global footprint and achievements by honouring Hydraulics Online with its coveted ‘Export Champion‘ status every year since 2019.

The utmost accolade came when Helen was awarded an MBE in The King’s Birthday Honours List for services to Business and to Exports, as announced in the London Gazette on 15th June 2024.

Our mission, vision and values

Our mission is simple:

Offer personal service, impartial technical advice and unrivalled choice. Every time.

Our vision is crystal clear:

To be the world’s leading provider of fluid power solutions; an independent and agile ‘hub’ connecting a fragmented, product-led marketplace.

Our values are uncompromising:

Deliver customer-centric solutions; drive quality and innovation; collaborate widely and inspire others.

Hydraulics Online are the only company we’ve come across where we are able to give them these problem scenarios and they come back to us with a solution. They have a vast knowledge of their technology and of system design and, because they are independent and not tied to any one manufacturer, I know they are giving us the best solution and the best products for that solution.
