Management consulting, built around your business
Every engagement is tailored. We work alongside owners and leadership teams — not from a distance — to solve the problems that matter most right now.
Strategy & Planning
Turn a vision into a clear, costed roadmap — market positioning, priorities and measurable milestones you can actually act on.
Operations & Systems
Streamline the day-to-day. We map your processes, remove bottlenecks and put the right tools and workflows in place.
Financial Planning
Budgets, forecasts and cash-flow modelling that make your numbers legible — and your next decision an easy one.
Performance & Reporting
KPIs and dashboards that tell you what's working. Regular reviews keep the whole team pointed the same way.
People & Structure
Organisational design, roles and hiring plans that scale with you — so growth doesn't outrun your team.
Growth & Expansion
New markets, new sites, new lines. We pressure-test the plan and support you through the launch.
A straightforward, four-step engagement
No jargon and no 200-slide decks that gather dust. Just a clear method that gets you from question to result.
- 01
Discover
We start by listening. A deep-dive into your goals, numbers and day-to-day reality to understand where you really are.
- 02
Diagnose
We identify the constraints holding you back and the highest-leverage opportunities — backed by evidence, not guesswork.
- 03
Design
Together we build a practical plan: clear priorities, owners, timelines and the metrics we'll track along the way.
- 04
Deliver
We stay hands-on through implementation, adjusting as we learn, until the change is embedded and working.
Rooted in Elephant & Castle, working across the capital
We founded Meridian & Castle to give ambitious smaller businesses the kind of rigorous, senior-level advice usually reserved for large corporations — delivered with the warmth and directness of a local partner. From our base in SE1, we support founders, family businesses and leadership teams right across London.
- A local team that knows London's business landscape first-hand
- Senior consultants on every engagement — never handed off to juniors
- Fixed-scope proposals with transparent pricing, no surprises
- Practical delivery support, not just recommendations on paper
Trusted by businesses across London
“Meridian & Castle rebuilt our forecasting and gave us a plan we could take to the bank. We secured funding within three months and opened our second site.”
“They cut through the noise. Within weeks our operations were tighter, our margins clearer, and the whole team knew exactly what they were accountable for.”
“Genuinely senior advice, delivered like a partner rather than a supplier. The growth strategy they built is still guiding us two years on.”
