About us

Two areas of senior expertise. One trusted partner.

Ledger & Lock is a founder-led advisory business. Our primary focus is senior financial leadership for owner-managed businesses, complemented by specialist cybersecurity and information security expertise.

Why we exist

Growing businesses deserve senior expertise they can actually access.

Owner-managed businesses with £2m to £10m turnover are the backbone of the UK economy. They make, build, move and sell. Many have outgrown a bookkeeper and a year-end accountant, but are not ready for a full-time Finance Director.

At the same time, they depend on technology as much as any larger company, and the risks of fraud, cyber attack and disruption are financial as much as technical.

We set up Ledger & Lock to give these businesses the senior financial leadership they need to grow with confidence, and the specialist security expertise to protect what they have built.

The founders

Finance leadership and cybersecurity leadership, side by side.

Ledger & Lock is run by its two co-founders, who do the work themselves. You'll meet them both in your first conversation.

How the two fit together

Finance leads. Security strengthens it.

Most clients come to us for financial leadership. Some need specialist security support. Where the two meet, in financial controls, fraud prevention, cyber risk and resilience, our combined perspective means we look at both what could go wrong and what it would cost.

Finance

Reporting, forecasting, cash, margins, controls and transformation.

Cybersecurity

Cyber risk, ISO 27001 compliance, control reviews and improvement.

Business resilience

Fraud prevention, financial controls, cyber risk and continuity.

How we work

Our principles

Straight talking

We tell you what we find, what matters and what doesn't, without jargon, scare tactics or upselling.

Commercially minded

We focus on what moves the numbers and protects the business, prioritised by impact and cost.

Independent

We don't resell products, take commissions or replace your accountant or IT provider.

Practical

We favour changes that work in a busy business with real people, real suppliers and real deadlines.

What we are not

Being clear about this helps you make the right decisions:

Not a traditional accountancy practice: no bookkeeping, payroll or tax returns
Not an IT support company: we work alongside yours
Not a 24/7 monitoring or emergency incident response service
Not a certification body for ISO 27001 or Cyber Essentials
Not an insurer or insurance broker
Not able to guarantee you will never suffer an incident (no one honestly can)
