Choosing a corporate solicitor is one of the more consequential decisions a business owner makes, yet it rarely happens often enough to get comfortable with. Whether you are selling a company you have spent decades building, raising an investment round, structuring a management buyout or simply formalising how a growing business is governed, the quality of the legal advice behind the deal shapes the outcome long after completion. The difficulty is that almost every firm describes itself in similar terms, which makes it hard to tell genuine corporate strength from marketing. The five firms below take very different approaches to corporate law, and each is likely to suit a different kind of business.
How this list was compiled
This is an editorial selection drawn from publicly available information, including each firm’s own published material, independent legal directories and the way these firms surface for corporate-law search terms in the UK. It is not a ranked scoring of legal quality, and none of the firms was instructed, tested or assessed first-hand for this article. The aim is to map the market – from regional specialists to large national practices – so readers can match a firm to their own circumstances rather than to a single notion of “best”.

1. Higgs LLP – partner-led corporate advice for the mid-market
Higgs is a full-service West Midlands firm offering senior, deal-focused advice without the remove of a large-firm structure. The firm’s corporate solicitors describe their team as one of the largest and most active in the Midlands, advising on corporate transactions both nationally and internationally, and the firm reports more than £230m in aggregate deal value over the past year.
A notable feature of Higgs’s published material is the breadth of the corporate offering combined with a partner-led approach. The team works across mergers and acquisitions, disposals, private equity and venture capital investment, management buyouts and buy-ins, employee ownership trusts, corporate governance and business succession planning. It acts for a wide spread of clients – from owner-managed and family businesses through to PLCs and private equity houses – and draws on in-house tax, banking, commercial, intellectual property, employment, property and private client specialists so that a transaction and its tax and personal-planning consequences are handled together.
Typically suits: owner-managed and mid-market businesses approaching a sale, acquisition, investment or succession event.
Notable strength: a sizeable, active regional corporate team offering full-service support under partner-led relationships.
Headquarters: Brierley Hill, West Midlands, with advice delivered nationally.
2. Blake Morgan – a national full-service corporate practice
Blake Morgan is a national full-service firm built to handle transactions across a wide range of values. According to its own published material, the firm advises on mergers, acquisitions, disposals, joint ventures, private equity investments and business restructures, handling more than 100 transactions a year with deal values ranging from below £5m to over £100m.
The firm operates from offices across the UK and positions itself as a full-service practice, with corporate work supported by specialists in banking and finance, pensions, intellectual property, technology, tax, competition, employment and real estate. Its corporate client base spans the owners and managers of small and medium-sized businesses through to the boards of major corporates and private-equity-backed deals, and the firm regularly supports cross-border transactions by coordinating with international advisers. That combination is geared to companies whose legal needs reach well beyond the transaction itself, or whose deals sit at the larger end of the mid-market.
Typically suits: businesses wanting national coverage and a broad deal-value range under one roof.
Notable strength: high transaction volume across a wide value spectrum, backed by full-service support teams.
Footprint: nationwide UK offices.
3. Harper James – a subscription model built for growing businesses
Harper James takes a different commercial approach to most corporate firms, orienting its model around ambitious early-stage and scaling companies. The firm describes itself as a “new breed” of national commercial law firm, built around subscription plans and fixed-fee products as an alternative to the traditional hourly billing model.
The firm provides corporate and commercial advice across the business lifecycle – from start-up and fundraising through to scaling and eventual exit – alongside employment, intellectual property, banking and finance, commercial property and employee share schemes. Its three service plans – Engage, Enable and Extend – and its fixed-fee products are designed, in the firm’s words, to deliver partner-level expertise from experienced solicitors at significant savings on traditional city-firm prices, with the Extend subscription adding dedicated account management. For founders who value cost certainty and a single point of contact, that predictable structure is the firm’s defining feature.
Typically suits: startups, scale-ups and SMEs wanting predictable, budget-led legal costs.
Notable strength: subscription and fixed-fee plans with dedicated account management.
Footprint: national, built around a remote-first model.
4. MBM Commercial – a specialist for entrepreneurial, high-growth businesses
MBM Commercial has built its identity around entrepreneurial, high-growth companies. An award-winning firm that rebranded in 2019 as “Entrepreneurial Business Lawyers”, it focuses on helping ambitious businesses start up, scale up and go global.
Founded in Edinburgh in 2005 and now also operating from London, MBM offers a full range of commercial legal services, with particular emphasis on the corporate work that growth businesses need – capital raising, EIS/SEIS investment, mergers and acquisitions and restructuring – supported by intellectual property, commercial contracts, commercial property, banking and finance, disputes and employment teams. Over the years it has grown from its early-stage roots to advise on larger and international transactions, including US deals, while keeping its focus on founders and growing companies.
Typically suits: founders and high-growth companies, from start-up through scale-up.
Notable strength: capital raising, EIS/SEIS investment and corporate transactions for entrepreneurial businesses.
Footprint: Edinburgh and London.
5. Irwin Mitchell – large-firm breadth and reach
Irwin Mitchell offers the scale and reach of a large national firm. A long-established full-service practice operating from more than 20 UK offices, it advises on the full corporate lifecycle, from company formation and expansion by acquisition through joint ventures, capital raising and funding rounds to a sale or other exit.
Its corporate and finance lawyers act for clients ranging from SMEs to international groups, alongside management teams and private equity-backed companies. A distinctive feature is the firm’s substantial private client and wealth practice alongside its business arm, which lets it advise the owners of a business in both their corporate and personal capacities – relevant where a transaction has significant implications for the individuals behind it.
Typically suits: larger or more complex businesses, and owners wanting combined corporate and personal advice.
Notable strength: national scale and a combined business and private client/wealth offering.
Footprint: more than 20 UK offices.
What to weigh when comparing corporate solicitors
The right corporate solicitor depends far more on the nature of a business and its transaction than on any single ranking. A few practical factors help narrow the field.
The starting point is usually the deal itself. A straightforward share sale of an owner-managed business has different demands from a venture capital fundraising or a multi-jurisdictional acquisition, and firms tend to be stronger in some of these than others. Matching a firm’s stated focus to the situation helps: MBM Commercial and Harper James orient heavily towards founders and growth businesses, while Irwin Mitchell and Blake Morgan offer the breadth and scale that larger or more complex matters often require. Higgs sits in the mid-market space, combining a sizeable regional corporate team with full-service support.
The cost model is another factor. Traditional firms generally bill by the hour, whereas Harper James is built around subscription and fixed-fee plans – a meaningful difference where budget predictability matters. Full-service support is worth weighing too: most corporate deals touch tax, employment, property and intellectual property, and a firm with those specialists in-house can coordinate them rather than leaving the client to manage several advisers. Other considerations include sector experience, the seniority of the lawyers who will actually run the matter, and the working relationship – corporate transactions are intense, and rapport with the lead adviser counts for a great deal. Every firm here is an authorised and regulated firm of solicitors – the baseline worth confirming on the relevant regulator’s register for any firm under consideration.
Frequently asked questions
What does a corporate solicitor do? A corporate solicitor advises businesses on transactions and structural matters such as buying and selling companies, mergers and acquisitions, investment and fundraising, shareholder and joint venture arrangements, corporate governance and succession or exit planning. The role centres on getting deals done while protecting the client’s legal and commercial interests.
What is the difference between a corporate solicitor and a commercial solicitor? Corporate solicitors focus on the ownership and structure of a business – share sales, acquisitions, investments and reorganisations – whereas commercial solicitors deal with the day-to-day contracts and trading arrangements a business relies on, such as supply agreements, terms and conditions and licensing. Many firms, including all five featured here, offer both.
How do I choose the right corporate solicitor for my business? Choosing a firm tends to come down to matching it to the specific transaction and business stage, checking whether the cost model fits the budget, confirming the relevant specialists (tax, employment, property, intellectual property) are available, and weighing the seniority and approachability of the lawyers who would handle the matter. It is also worth confirming the firm is properly authorised and regulated as a firm of solicitors.
How much do corporate solicitors charge? Fees vary widely with the complexity and value of the work, and pricing models differ between firms. Most charge by the hour or on a deal-by-deal basis, while some, such as Harper James, offer subscription or fixed-fee arrangements. It is reasonable to ask any firm for an estimate or a fee structure before instructing them.
Do startups and small businesses need a corporate solicitor? Often, yes – particularly when raising investment, issuing shares, agreeing terms between founders or preparing for a sale. Several firms, including Harper James and MBM Commercial, structure their services specifically around the needs and budgets of startups and growing businesses.
Final thoughts
There is no single best corporate solicitor for every business, which is why this list spans regional specialists, national full-service firms, a subscription-based practice and a large-firm option. For owner-managed and mid-market businesses wanting senior, partner-led support across the full deal lifecycle, Higgs LLP fits that profile closely, with a sizeable, active corporate team and a full-service offering. The right firm, though, is the one whose focus, cost model and approach fit the business in question.
