How is an in-house legal consultancy different from a law firm?

Most businesses assume there are only two options for legal support: instruct a law firm when something comes up, or hire a full time general counsel once the business is big enough to justify the cost. Neither option fits well for a business turning over 50 million to 200 million pounds with a genuinely high volume of contracts. That gap is exactly what an in-house legal consultancy is designed to fill, and the reason this model exists at all traces back to a regulatory change most business owners have never heard of.

The 2019 change that made this possible

In November 2019, the Solicitors Regulation Authority introduced its new Standards and Regulations, which came into force on 25 November 2019. Before that date, a solicitor providing legal services generally needed to do so through a firm authorised and regulated by the SRA, with the cost structure, insurance arrangements and overhead that comes with running a regulated law firm or LLP.

The 2019 Standards and Regulations changed that. They allow solicitors to deliver non-reserved legal services, meaning everything short of activities such as litigation, conveyancing and probate, from a business that is not itself an authorised law firm, including on a freelance or consultancy basis. That is a significant shift. It means an experienced solicitor can offer commercial legal advice, contract negotiation, governance support and privacy work through a consultancy structure, insured for business advice rather than carrying the full regulatory apparatus of a traditional law firm.

Why that keeps the cost down

This is not a loophole. It is a deliberate regulatory change that recognised businesses needed more flexible access to legal expertise. Because a consultancy model does not carry the same overhead as a law firm structure, and because the work does not involve reserved legal activities, the saving can be passed directly to clients through a monthly retainer instead of hourly billing. That is how a retainer of roughly 1,000 to 5,000 pounds a month buys senior legal judgement that would otherwise cost a multiple of that through a traditional law firm.

The gap between 50 million and 200 million pounds

Businesses in this revenue range have usually outgrown the point where founders or operations leads can safely review every contract themselves. Contract volume is high, supplier and customer relationships are more complex, and privacy and governance obligations are real. But the workload is not always constant enough, or large enough, to justify a full time general counsel with the salary, pension, benefits and recruitment cost that comes with it.

That is the gap Adaptable Legal Counsel is designed to fill. We provide the same scope of support as an internal legal counsel, contract negotiation, privacy review, governance and legal ops, on a retainer that scales with your actual workload rather than a fixed headcount cost.

Frontier AI, used to move faster

The other half of the equation is speed. We use frontier AI tools, principally Claude, to accelerate first-pass contract review, comparison against playbooks and drafting of standard clauses. That does not replace legal judgement. It removes the administrative time that used to sit between a question landing and a qualified answer being ready, which is part of how the same lawyer can support more businesses without stretching quality thin.

The result is a model built for the specific gap between ad hoc external advice and a full time hire: qualified, experienced legal judgement, delivered through a consultancy structure that the law itself has allowed since 2019, sped up with the same AI tools reshaping how legal work gets done everywhere else.
