What is a Fractional General Counsel and do I need one for my UK business?

THE MODEL

What a fractional general counsel actually does

The title causes some confusion. A fractional general counsel is not a part-time solicitor or a legal helpline. It is a senior lawyer - typically with 15 to 25 years of commercial legal experience, usually at partner level in private practice, in-house at a significant business, or both - who works with your organisation on a flexible basis rather than as a full-time employee.

The distinction from a traditional law firm engagement matters. When you instruct a law firm on a matter, you are buying matter-specific advice. A solicitor who does not know your business, your commercial priorities, or your risk appetite picks up your file, does the work, and moves on. The fractional GC model is the opposite of this. Your fractional GC becomes embedded in the business. They attend board meetings, review commercial relationships, provide strategic input on transactions in progress, and are available between matters - not just when something goes wrong.

The IBA describes the model as combining ‘in-house proximity with specialist external expertise’. That is an accurate summary. You get a lawyer who thinks like a business partner, not a service provider billing by the six-minute unit.

What a fractional GC does day to day:

•     Reviewing, negotiating and closing commercial contracts

•     Advising on regulatory compliance obligations - EU AI Act, GDPR, DORA, sector-specific regulation

•     Providing strategic legal input at board and executive level

•     Managing and coordinating external counsel on specialist matters

•     Drafting and maintaining legal playbooks, contract templates and internal governance frameworks

•     Supporting fundraising rounds, M&A processes and due diligence

•     Acting as a legal sounding board for the CEO, CFO and leadership team

•     Covering capacity gaps when in-house legal resource is overstretched or absent


THE REAL COST

What a fractional general counsel costs in the UK - and what you are comparing it against

The cost question is the one most businesses ask first and most providers answer vaguely. Here is a direct answer.

A full-time General Counsel in the UK commands a base salary of between £120,000 and £250,000 depending on seniority and sector. Add employer National Insurance at 15%, pension contributions, private medical insurance, bonus and other benefits, and the true employer cost reaches £175,000 to £310,000 per year. That is before the recruitment fee, which for a senior hire typically runs between 20% and 30% of first-year salary. And before the three to six months it takes to hire, onboard and get a new GC up to speed on your business.

The fractional model eliminates every one of those additional costs. You are engaging a limited company contractor. There is no employer NIC. No pension obligation. No statutory leave. No recruitment fee. No onboarding period - a good fractional GC should be operationally useful within days, not months.

The right comparison is not fractional GC fees against a law firm's hourly rate. It is fractional GC fees against the fully loaded cost of a senior in-house hire. Against that benchmark, the model typically delivers a 50 to 70 percent saving at equivalent seniority - with the added advantage of flexibility to scale up or down as your business requires. Fractional GC retainers in the UK typically range from £3,000 to £12,000 per month depending on scope and seniority, compared to a true employer cost of £175,000 to £310,000 per year for a full-time General Counsel


WHO NEEDS ONE

Five signals that your business needs a fractional general counsel

The fractional GC model is not right for every business at every stage. Here are the five situations where the case for engaging one becomes compelling.

1. You are closing bigger deals without senior legal support

The contract that adds £500,000 of annual recurring revenue is not the moment to rely on a junior solicitor or a contract review tool. Commercial agreements at scale - SaaS licensing, outsourcing arrangements, technology partnerships, distribution agreements - require a lawyer who has sat on both sides of the negotiating table on deals of comparable complexity. When the counterparty has a seasoned GC and you do not, you are exposed.

2. Your regulatory environment is getting more complex

The EU AI Act, GDPR, DORA, NIS2 and the broader digital regulatory landscape are not administrative burdens that can be managed with occasional external counsel. They require ongoing legal oversight embedded in your operations. If your business uses AI in any commercial capacity, operates in financial services, handles personal data at scale, or has European customers, you are already in a regulated environment that demands senior legal engagement.

3. Your in-house team is overstretched

The most common catalyst for engaging a fractional GC is not absence of legal resource - it is insufficiency of it. A single in-house solicitor managing a growing business’s full legal workload is a risk, not a solution. A fractional GC augments that team, handles specialist work outside their expertise, and provides senior cover during periods of high volume.

4. You are preparing for a significant corporate event

Fundraising rounds, M&A transactions, international expansion, and major outsourcing programmes all create concentrated periods of high legal demand. A fractional GC can be engaged specifically for these events - managing external counsel, leading on due diligence, structuring the transaction, and ensuring the business is protected at a moment when the stakes are highest.

5. You cannot yet justify a full-time hire but you need the capability now

This is the most common scenario for scale-ups and high-growth businesses. The business is past the stage where founders can manage legal risk alone, but not yet generating the revenue that justifies a £200,000 annual salary commitment. The fractional model bridges exactly this gap - providing full GC capability at a cost that is proportionate to the current stage of the business.


THE AI DIMENSION

Why AI governance makes the fractional GC model more valuable, not less

Every business we speak to is either deploying AI tools, evaluating them, or being asked by clients and counterparties to account for how they are used. The legal implications of that shift are not marginal. They are central to commercial risk management in 2026.

AI contracts require entirely different provisions from standard commercial agreements. Liability for AI hallucinations and collisions. Ownership of model outputs and training data. Audit rights. Compliance warranties linked to the EU AI Act. Change notification obligations. These are not standard commercial law clauses - they require a lawyer who understands the technology, the regulatory framework, and how those provisions function under pressure.

The EU AI Act introduces obligations that most businesses have not yet fully mapped. Prohibited AI practices have been enforceable since February 2025. High-risk AI system obligations apply from 2 August 2026. Many businesses will discover that their HR software, fraud detection tools or customer scoring systems are classified as high-risk under the Act — and that their vendor agreements do not currently give them the rights they need to comply.

A fractional GC with genuine AI law specialism - not a commercial lawyer who has added AI to their service list - provides exactly the oversight that businesses navigating this landscape need. This is the specific capability gap that most generalist fractional GC providers cannot fill.

“AI is not the risk. AI without oversight is.”

The fractional GC market has grown rapidly. Quality varies enormously. These are the questions worth asking before signing an engagement letter.


HOW IT WORKS

Fractional general counsel at RMOK Legal

RMOK Legal is led personally by Rory O'Keeffe - former Partner at Matheson, a top-tier European law firm, and former Director of Legal Services at Accenture, where he managed a team of senior lawyers handling over £2 billion in annual contract value across more than 40 industries. Every engagement is led directly by Rory. There is no junior team, no platform, no handoff. You get 20 years of senior commercial and technology law experience applied directly to your business.

Where engagements require additional capacity or specialist expertise - whether that is a complex piece of contentious work, a specialist regulatory matter, or a transaction requiring additional senior resource - Rory draws on a network of senior lawyers and boutique law firms contracted to RMOK Legal. This means clients benefit from the continuity and commercial judgment of a single trusted lawyer, with the ability to scale legal resource around specific needs without having to brief an entirely new firm from scratch.

That specialism in AI governance, EU AI Act compliance and technology contracting is not a service line added to meet market demand. It is where Rory's career has been pointing for a decade - from criminal law in Dublin, through corporate, construction, engineering, arbitration and technology, to the AI regulatory landscape that is now reshaping every commercial relationship. He sits on the AI Committee of the Society for Computers and Law, holds SCL accreditation as a Leading IT Lawyer, and is the author of AI Advantage: Thriving Within Civilisation's Next Big Disruption (2025). He also built and runs a business himself - which means when he advises on commercial risk, he understands what is actually at stake.

“A safe pair of hands on our most complex commercial deals.”
