The Event Book is a London-based, full-service event management agency, founded by Ria Thomas in February 2020, built on more than 20 years of hands-on experience in the events industry.
The agency was created to bring together Ria’s carefully curated “little black book” of trusted venues, suppliers and production partners — relationships built through decades of delivering corporate events, conferences, hospitality experiences and international programmes.
Today, The Event Book supports UK and global clients with the planning, management and delivery of high-quality corporate events in London and internationally.
What Makes The Event Book Different from Other London Event Agencies?
When companies search for a London event management agency, they are usually looking for three things:
- Experience
- Reliability
- A team they can trust with senior stakeholders and budgets
The Event Book stands out because it is founder-led, experience-driven and relationship-based.
Every event is overseen by a senior team that understands:
- Corporate decision-making
- Procurement and budget management
- C-suite expectations
- International logistics and delivery
Clients are not passed to junior teams or freelancers without oversight. Your event brief is managed by people who have planned, delivered and solved problems in real-world event environments for over two decades.
A London Event Management Team Built on Trusted Supplier Relationships
At the core of The Event Book is Ria Thomas’s little black book — a network of tried, tested and trusted event suppliers built over 20+ years.
This includes:
- London venues and international hotels
- AV, production and staging partners
- Creative, branding and design suppliers
- Entertainment and hospitality partners
These are suppliers we have worked with repeatedly, not sourced at speed.
This approach ensures:
- Better value and negotiation
- Faster turnaround times
- Reliable delivery
- Fewer risks on live events
For clients, this means confidence — and events that run smoothly.
Full-Service Corporate Event Management in London & Beyond
The Event Book provides end-to-end event management, acting as a single point of contact from brief to delivery.

- Sales kick-offs and leadership offsites
- Corporate hospitality and VIP experiences
