About Us

About Us

Based in Hertfordshire, we deliver events in-person, online and blended throughout the world. 

Established in 1992 and with many long-standing clients, we design, manage and produce business events from inception to conclusion, or in conjunction with your in-house team.

Whether a conference, awards ceremony, product launch or social event and in whatever format – on a live event stage, in a broadcast studio or via webcam – there is very little we haven’t experienced or learned along the way.

We’ve worked extensively in the UK and throughout the world, taking UK audiences to every continent of the globe and uniting global audiences online.

We are a small business with big event experience. If you have an event ambition of any shape or size, our friendly and talented team are here to help.

Meet Us

I fell into the world of events whilst working for Middle East Travel magazine. After travelling to Dubai to assist with the publisher’s Arab Travel conference and exhibition – at a time when Dubai was still mainly desert with a few hotels along Dubai Creek – I realised then that event management was the career for me.

A few years later I joined ABTA to work on the Association’s annual overseas Convention – a five day jamboree of conference sessions and social events for 3000+ people – and Events (and travel) became my passion.

I founded Dellar Davies (formerly CO Plus) in early 1992 and so much has happened since! We’ve organised events all over the world and more recently, delegates from all over the world have joined our clients’ events online.

As a team we love what we do, who we do it for and above all, working together – what better way can there be to make a living!

We don’t make a habit of entering awards, however we decided to give it a go and entered two of our clients projects into different event awards in 2017 and 2018.

As event-awards novices, we were delighted to be short-listed for both awards and subsequently to pick up an accolade at both awards ceremonies!

The first was in the Best Association Conference category at the 2017 Conference Awards for The Travel Convention, on behalf of ABTA – The Travel Association.

The second was in the Best Association Awards category at the 2018 Awards Awards for The Travel Marketing Awards, on behalf of CIM Travel Group.
