Where It All Started

Component 27 – 3@2x

H2X Engineering was founded by engineers who were frustrated with the tedious process of traditional plumbing design methods.

The idea for H2X was sparked in 2019 by Jonathan Mousdell, a Senior Plumbing Engineer, who realised that traditional methods of designing plumbing systems were not only inefficient but often non-compliant and un-auditable.

Tired of paper drawings, measuring and counting components, and calculating results using various spreadsheets - he wanted something better for the industry.

Our Core Values

Created By Engineers For Engineers



Complete calculations in a fraction of the time.

Focus on the bigger picture and most importantly, make it home on time.



H2X calculates to a level of detail not previously possible.

Respond to RFI's with detailed calculation data.



Avoid human error and replace 'rule of thumb' with transparent, compliant and accurate engineering.



H2X enables innovative teams to standardise processes.

Auditing procedures can be effective rather than a tick box exercise.


The Journey

​It is incredible to look at how far we have come since we started out as a cold water pipe sizing tool. It is even more incredible to look at our exciting plans for the future.

Engineers are often surprised at how well we fit into their design workflow, and the depth at which we can help them - this is not a coincidence.

Since day 1, our users have been requesting features which has seen us grow into the service we offer today and what we will provide in the future.

What we are creating at H2X is aimed at improving the quality of the industry.

Our Mission

The Why Behind H2X

Our mission is to improve plumbing designs globally.

Unhealthy competition between engineering companies has caused lower project fees.

Coupled with the rise of 'Design & Construct' projects, this has led to a decrease in the quality of designs produced by engineers.

Did you know


of all defects come from the design phase?

H2X was born to change all of this


We knew we couldn't just improve one part of the plumbing engineer's design process.

Our involvement and improvement across the whole design process makes us unique.

Provide a central place for all design, calculations, and reviews to be undertaken

Begin with just a PDF of the architectural layout so you can start your design early in the project

Allow users to focus on the most important design tasks by automating tedious measuring and counting

Make it easy to update when the architect or engineers make changes or requests that affect your design
