Active Flow’s 10th Anniversary

It makes me so proud as a Director of Active Flow to announce that we have crossed another milestone in the history of our company, by entering its 10th year of establishment.

I want to take this opportunity to thank each and every one of you for being an earnest part of Active Flow.

What began as a small firm with just 3 members has risen up to stand tall amongst the business leaders of the time with more than 20 employees. We have countless achievements and accomplishments, especially over the last couple of years which have proved to be exceptionally productive, making innovative steps forward in a highly competitive industry.

Without the support of our excellent team, it would never have been possible to build the reputation and resilience we have now. Every one of you plays a very important role in the development of our company. It is your enthusiasm, support and dedication that has got us to where we are now.

We are also grateful to our customers who trusted in us to help them provide impeccable services and products. Their demands, challenges and feedback have pushed us to forge ahead and improve, time and time again. Our success story remains incomplete without the support of these clients and customers. Not only have they made us a part of their journey, but also helped us reach new heights. They spread the word faster and in a better way than any of our promotional means could.

We can’t thank you enough for your contributions to Active Flow. We want to keep our business and relationships growing with you, and continue to provide you with nothing less than the best. With your support, we look forward to the next 10 years of success.

Introducing Active Flow

Same Values, just a new look

We’re UK gas industry experts with sharp minds and even smarter designs.

Our brand was stuck in the past, and we needed to bring it up to date. Why? To reflect our expertise and the added value we offer our customers. With this in mind, we’ve shortened our name to Active Flow and we’ve shaken things up with a new look that reflects our substance – things like passion and great service.

Visually, our logo represents what we do; the flair of yellow you see has meaning. This is something we see everyday in our industry – so we’ve brought that through to our brand.

We have revamped our website as an extension of our new brand to create a solid footing for our business out there in the digital world.

What makes us Active Flow?

Passion. This is the fuel for what we do.

Invested in our people. Because when they grow, we grow together.

Nimble and agile. Think David and Goliath.

Innovative. Always reaching for new ideas and approaches.

Honest and transparent. Because you get back what you give.

Welcome to your revamped Active Flow.
