Private Equity Lawyers in London
Private equity lawyers London sponsors and management teams instruct structure buyouts, negotiate management equity, coordinate debt financing and manage exits. In 2026 the landscape has shifted: carried interest is now taxed within the income tax regime, fund manager regulation is under review, and national security screening reaches deep into fund structures.
Key pointFrom 6 April 2026 carried interest is taxed as trading profit within income tax, with only 72.5% of qualifying carry brought into charge, so carry plans designed for capital gains treatment need review.
At a glance
Carried interest reform
From 6 April 2026 carry is taxed as trading profit; qualifying carry is charged on 72.5% of its amount, giving roughly 34% for additional-rate taxpayers.
14-day section 431 deadline
Managers acquiring restricted shares should sign a joint section 431 election with the employer within 14 days to protect capital gains treatment on growth.
Leaver terms decide value
Good leavers usually receive market value and bad leavers the lower of cost and market value, so definitions matter more than the headline equity pool.
NSIA reaches funds
The government looks through fund structures to ultimate investors, and bolt-on acquisitions by portfolio companies can also require mandatory notification.
AIFM regime under review
The FCA and HM Treasury consulted in 2026 on a new UK AIFM regime with size-based tiers; final rules are expected later.

What private equity lawyers London sponsors and management teams instruct actually do
The private equity lawyers London funds, management teams and portfolio companies instruct work on the full life of a private equity investment: raising the fund, acquiring a business through a newly formed bid structure, financing it with debt, aligning management through equity incentives, running the portfolio company and, eventually, selling or listing it. Each stage has its own documents, tax rules and regulatory touchpoints.
In England and Wales the work combines company law under the Companies Act 2006, contract law, tax law on carried interest and management equity, financial regulation of fund managers by the Financial Conduct Authority, and the clearance regimes that apply to any acquisition. In 2026 several of those rules have shifted, most notably the taxation of carried interest and the government's ongoing reform of fund manager regulation.
This page explains how a UK buyout is structured, the decisions sponsors and management face, the process and documents, and the mistakes that most often cause friction. For general M&A mechanics, see our M&A page.
The legal and regulatory framework
There is no private equity statute. A buyout is an acquisition carried out through a chain of newly formed companies, and the rules that govern it come from several sources.
Company and contract law
The Companies Act 2006 governs the bid companies (usually a Topco, one or more intermediate holding companies and a Bidco), share classes, allotments and shareholder decisions. The investment agreement and articles of Topco set out the sponsor's control rights and the management team's obligations. The share purchase agreement with the seller follows ordinary M&A principles, often with a locked-box price and W&I insurance.
Fund and manager regulation
UK fund managers are authorised and supervised by the Financial Conduct Authority under the Financial Services and Markets Act 2000 and the UK rules derived from the EU Alternative Investment Fund Managers Directive. In 2026 the FCA consulted on a new UK AIFM regime, and HM Treasury published draft regulations alongside it, proposing size-based tiers measured by net asset value. Final rules are expected later, so managers should plan on the current regime while tracking the reform.
Fund-level transactions raise their own questions. GP-led secondaries and continuation funds, where a sponsor moves one or more assets from an older fund into a new vehicle, involve conflicts between the manager and existing investors. They require careful process, independent valuation evidence and clear disclosure to limited partners, and they are increasingly scrutinised by investors and regulators alike. Our investment funds team covers fund formation and authorisation.
Tax on carried interest and management equity
From 6 April 2026, carried interest is treated as trading profit within the income tax regime rather than as a capital gain. Qualifying carried interest is taxed on 72.5% of the amount, producing an effective rate of about 34% for an additional-rate taxpayer; carry that does not meet the average holding period conditions is taxed in full. Management equity remains subject to the employment-related securities rules in the Income Tax (Earnings and Pensions) Act 2003, so elections under section 431 and accurate valuations remain essential.
Deal clearances
Buyouts are subject to the same gates as any acquisition: mandatory notification under the National Security and Investment Act 2021 for targets in 17 sensitive sectors, CMA merger control where the post-January 2025 thresholds are met, and FCA change-in-control approval for regulated targets. Because sponsors acquire many companies, the CMA and the government look at a fund's overall portfolio, not just the individual deal.
Key decisions for sponsors and management
The most important negotiations in a buyout are often not with the seller but between the sponsor and the management team. These are the decisions private equity lawyers London clients most often ask us to help them think through.
| Instrument | Who holds it | Purpose | Key negotiation points |
|---|---|---|---|
| Institutional strip (loan notes or preference shares plus ordinary shares) | Sponsor, sometimes rolling sellers | Delivers the sponsor's priority return | Coupon rate, ranking, whether it compounds |
| Sweet equity (ordinary shares) | Management | Gives management upside above the sponsor's return | Size of pool, price paid, ratchets, leaver terms |
| Rollover equity | Selling founders | Keeps sellers invested in the next phase | Whether it is in the strip or sweet, tax-efficient rollover |
| Senior and unitranche debt | Banks or private credit funds | Funds most of the price | Covenants, security, permitted distributions |
Sweet equity and ratchets
Management's reward comes from sweet equity: ordinary shares bought at a low price because the institutional strip sits ahead of them. A ratchet increases management's share if the sponsor's return exceeds an agreed hurdle. The value of sweet equity at subscription must be supportable to HMRC, because an undervalue can create an income tax charge on day one.
Rollover for selling founders
Founders who sell to a sponsor are often asked to reinvest part of their proceeds. Rolling into Topco shares in exchange for target shares can qualify for share-for-share treatment under section 135 of the Taxation of Chargeable Gains Act 1992, deferring capital gains tax until the Topco shares are sold, provided the exchange is for bona fide commercial reasons. Advance clearance from HMRC is commonly sought. Founders should also decide whether their rollover sits in the institutional strip, alongside the sponsor, or in the sweet equity, alongside management, since the risk and reward profile differs sharply.
Leaver provisions
If a manager leaves, the articles usually require them to sell their shares. A good leaver (death, ill health, redundancy) receives market value; a bad leaver (resignation, dismissal for cause, breach of covenants) receives the lower of cost and market value. Intermediate categories and vesting schedules are common. These clauses decide what management actually takes home, so they deserve as much attention as the headline equity percentage.
Sponsor control rights
Sponsors take extensive consent rights over budgets, acquisitions, borrowing, hiring and disposals, plus board appointment rights and step-in rights if performance or covenants slip. Management should negotiate reasonable thresholds, clear information obligations, and a realistic process for obtaining consent so that the business is not run by default from the fund's office.
Management teams often negotiate hard on the size of the sweet equity pool and then accept leaver terms that decide whether they ever see it.
The buyout process and timeline
- Origination and exclusivity. The sponsor bids in an auction or negotiates bilaterally, often offering a locked-box price backed by committed funding.
- Due diligence. Financial, tax, legal, commercial and sometimes ESG diligence is commissioned, partly to support W&I insurance and debt financing.
- Structuring. Topco, Midco and Bidco are formed, often with an offshore or UK holding structure, and the capital structure is modelled.
- Management negotiations. The management term sheet covers sweet equity, rollover, leaver terms, warranties from management and service agreements.
- Financing. Debt documents are negotiated with banks or private credit lenders, with security over the target group granted at or after completion.
- Signing and clearances. The SPA is signed; NSIA, CMA, FCA or sector approvals are sought where needed.
- Completion. Funds flow through the structure, the target is acquired, management subscribe for shares and tax elections are made within the statutory deadlines.
- Portfolio management and exit. The sponsor monitors performance, makes bolt-on acquisitions, refinances, and ultimately sells to a trade buyer, another sponsor or through a listing.
Exit routes compared
The exit shapes returns more than any other event in the life of an investment, and the Topco articles should anticipate it from day one. A trade sale to a strategic buyer often achieves the highest price but involves competition and regulatory review and usually requires sellers to give warranties, commonly backed by W&I insurance. A secondary buyout to another sponsor is typically faster and familiar to both sides, and management may be asked to reinvest again.
A listing on the London Stock Exchange gives a partial exit and public currency for future acquisitions, but the sponsor is normally locked in for a period and sells down over time. Continuation funds allow a sponsor to keep a strong asset while giving existing investors the option of liquidity. Drag-along rights in the articles ensure that minority holders, including management, cannot block a sale that the sponsor and the required majority support.
Key documents and evidence
Investment agreement
Governs the relationship between the sponsor and management: warranties from management, sponsor consent rights, information rights and restrictive covenants.
Topco articles
Set out share classes, transfer restrictions, leaver provisions, drag and tag rights, pre-emption, and the waterfall on exit.
Share purchase agreement
The acquisition agreement with the seller, typically with a locked-box price, limited seller warranties and W&I insurance standing behind them.
Debt finance documents
Facility agreement, intercreditor agreement and security documents. See our leveraged finance page.
Management service agreements
New employment contracts for managers with notice periods, restrictive covenants and garden leave aligned with the leaver provisions.
Tax elections and valuations
Section 431 elections signed within 14 days of acquisition, and valuation evidence supporting the subscription price of sweet equity.
Risks and common mistakes
Missing the section 431 election deadline
When managers acquire shares in a buyout, the shares are usually restricted securities for tax purposes. A joint election between employer and employee under section 431 of the Income Tax (Earnings and Pensions) Act 2003 brings the full unrestricted market value into account at acquisition, so that future growth is taxed as a capital gain rather than as employment income. The election must be made within 14 days of acquisition. Missing it can turn part of the eventual exit proceeds into income taxed at much higher rates, and it cannot be cured afterwards.
Misaligned articles and investment agreement
The articles bind all shareholders and future transferees; the investment agreement binds only the signatories. Where the two conflict on leaver mechanics, drag-along or consent rights, disputes follow, usually at the worst moment: on a manager's departure or on exit. Both documents should be drafted together, tested against realistic scenarios such as a partial exit or a refinancing, and updated whenever new managers are added to the equity.
Underestimating NSIA on portfolio companies
Private equity buyers are frequently foreign-funded, and the National Security and Investment Act 2021 looks at the ultimate investors in a fund as well as the fund itself. Bolt-on acquisitions by a portfolio company can also be notifiable. Because a notifiable acquisition completed without approval is void, sponsors should screen each deal, including small add-ons, against the current sector definitions, which the government confirmed in March 2026 it will revise.
Management warranties without limits
Sponsors usually ask management to warrant the business plan and the accuracy of information given in diligence. Without caps tied to each manager's proceeds or investment, time limits, and a requirement that the sponsor did not already know of the issue, these warranties can expose managers personally. They are intended to encourage disclosure, not as a route to recovering losses, and the drafting should say so clearly.
Carried interest structured on outdated assumptions
From 6 April 2026 carried interest is taxed within the income tax regime, with only 72.5% of qualifying carry brought into charge. Whether carry qualifies depends on the fund's average holding period of investments, and non-qualifying carry is taxed in full. Fund documents and carry plans designed for the old capital gains treatment should be reviewed, particularly for funds with short holding periods or frequent partial exits, and for executives with international mobility.
Overlooking debt pushdown and upstream guarantees
Lenders want guarantees and security from the target group, not just from Bidco. For private companies the old prohibition on financial assistance was abolished, but it still applies to public companies and to their subsidiaries assisting the acquisition of the public company's shares, so a take-private may need the target to re-register as private first. Directors of each guaranteeing company must also be satisfied that giving the guarantee promotes the success of that company under section 172, and corporate benefit should be minuted. Distributions used to push debt up the structure must be lawful, made out of distributable reserves shown in relevant accounts.
Management teams should take independent legal advice on the management term sheet before it is signed. Once headline terms on sweet equity, ratchets and leaver categories are agreed, sponsors are reluctant to reopen them in the long-form documents.
Cross-border private equity: Bangladesh, the Gulf, Europe and Asia
London private equity increasingly involves capital from the Gulf, Singapore and wider Asia, and targets with operations in South Asia. Bid structures often include holding companies in other jurisdictions, and each layer must be checked for tax residence, substance and treaty access.
For Bangladeshi portfolio companies, the Companies Act 1994 and the Registrar of Joint Stock Companies and Firms govern corporate changes, while Bangladesh Bank controls repatriation of dividends and sale proceeds. Investment incentives and registration for foreign-owned businesses run through the Bangladesh Investment Development Authority. Exit planning should confirm early that proceeds can be remitted out of Bangladesh. Our investing in Bangladesh team works with TRW & Co's Dhaka office on these questions.
For private equity lawyers London advising on cross-border buyouts, the choice of governing law and forum matters. English law investment agreements with London-seated arbitration are common where co-investors are based in jurisdictions where enforcing an English judgment could be slow.
Gulf sovereign and family office investors increasingly co-invest alongside London sponsors. Their participation may trigger NSIA scrutiny and should be disclosed early in the process. EU targets may need separate foreign investment screening filings under national regimes.

Choosing private equity lawyers in London
When choosing private equity lawyers London firms offer, sponsors should look for teams who can coordinate the acquisition, the financing and the management equity on one timetable, because each set of documents depends on the others. Management teams need advisers independent of the sponsor's firm, who understand market norms on sweet equity and leaver terms and can explain the tax consequences clearly.
For cross-border investments, ask how the firm will handle the jurisdictions beyond the UK. TRW & Co's offices in Dhaka, Singapore, Dubai and elsewhere allow us to coordinate local law input directly. As private equity lawyers London with that reach, we can follow a deal from the London holding company down to the operating subsidiary.
Finally, look for continuity between deal and portfolio work. The advisers who negotiate the investment documents are best placed to apply them later when a manager leaves, a bolt-on needs sponsor consent or the business is prepared for sale. Consistent interpretation of leaver and consent clauses over a holding period of several years avoids disputes that otherwise arise when new advisers read old documents without the negotiating history.

Frequently asked questions
01What is sweet equity in a private equity buyout?
Sweet equity is the ordinary share capital that management buys in Topco at a low price because the sponsor's institutional strip of loan notes or preference shares ranks ahead of it. If the business grows, the ordinary shares capture a disproportionate share of the upside, rewarding management for performance. The subscription price must be supportable as market value for tax purposes, and the shares are normally subject to leaver provisions and sometimes a ratchet linked to the sponsor's returns.
02How are management teams treated if they leave?
The Topco articles usually require a departing manager to sell their shares. Good leavers, typically on death, ill health or sometimes redundancy, receive market value. Bad leavers, typically on resignation, gross misconduct or breach of restrictive covenants, receive the lower of cost and market value. Many structures add intermediate categories or time-based vesting. The definitions, and who decides which category applies, determine what a manager actually receives, so they should be negotiated carefully.
03How is carried interest taxed from April 2026?
From 6 April 2026 carried interest is treated as trading profit within the income tax regime rather than as a capital gain. Qualifying carried interest is charged on 72.5% of its amount, which produces an effective rate of about 34% for an additional-rate taxpayer. Whether carry qualifies depends on the fund's average holding period for investments, and non-qualifying carry is taxed in full. Executives should review carry documents and their personal tax position with specialist tax advisers.
04Do management need their own lawyers?
Yes. The sponsor's lawyers act for the fund, and the target company's lawyers often act for the seller. Management are making a personal investment, giving personal warranties and accepting restrictive covenants and leaver terms, so they need independent advice. In many deals the sponsor agrees to meet a reasonable part of management's legal costs. Early advice on the term sheet is most valuable, because headline terms are hard to reopen later.
05Does a private equity deal need NSIA clearance?
It does if the target carries on activities within one of the 17 sensitive sectors and the acquisition crosses a control threshold, such as more than 25% of shares or votes. The government considers the fund's ultimate investors as well as the fund itself, and bolt-on acquisitions by portfolio companies can also be notifiable. Completing a notifiable acquisition without approval makes it void, so screening is part of every deal.
06What is a section 431 election?
It is a joint election between an employer and an employee under section 431 of the Income Tax (Earnings and Pensions) Act 2003. When management acquire shares subject to restrictions, such as leaver provisions, the election treats the shares as if unrestricted for tax at acquisition. Any income tax arises on day one on the small difference between market value and price paid, and future growth is then taxed as a capital gain. It must be made within 14 days of acquisition.
07Can TRW & Co advise on private equity investments in Bangladesh?
Yes. TRW & Co's London office advises on English law bid structures, investment agreements and management equity, and works with the firm's Dhaka office on Bangladeshi company law, BIDA registration and Bangladesh Bank rules on repatriating dividends and exit proceeds. This allows a sponsor to plan both ends of the structure, from the London holding company to the Bangladeshi operating business.
