Newcastle headquartered O.agency has started 2026 with a bang, welcoming multiple new retained clients to its roster, including national holiday park Verdant Leisure and fast growth tech and data business Seriös Group.
The agency has also welcomed the TSA (The Survey Association) as a new client, who alongside their cohort of industry experts are leading a 2026 UK Geospatial skills and awareness campaign across sectors, with O as the lead consultancy, creative and comms agency.
The O team also launched a campaign in December for new client Tullie Museum & Art Gallery, with ‘Find your Tullie’ – a campaign designed to bring the joy of Tullie and the different experiences it offers to life across digital and OOH.

This news follows a successful end to the agency’s milestone 20th year in 2025, including picking up a regional award for its work on Darlington Building Society’s ‘We Did That’ campaign – the society’s first ever integrated brand campaign, which generated over £19m new savings deposits.
The agency is currently recruiting for multiple roles, including social media roles and account managers in its comms and campaigns teams.
Kirsty Ostell, managing director of O.agency, said: “It’s fantastic to start the year adding to our client family for 2026, and with such incredible brands and teams. We are filled with ambition for 2026 and so are our clients, and it’s great to see not just new clients coming in with big plans, but our existing clients entering a new year with some very exciting campaigns. It’s our 21st year and the thing that makes us most proud is that we have clients who are entering their 20th, 18th and 15th years with us in 2026 too. Relationships and great work are all that matters.”
Izy Herrera, head of marketing at Seriös Group said: “Finding the right PR agency for Seriös Group was a big priority for me. We wanted a team that understood our business and our ambitions, as well as bringing the right energy and creativity we need to grow. From the start, Kirsty and Rachel from O.agency showed us that we’re not just another client to them, it’s a genuine partnership. They want to help us succeed.
