When an emerging manager tells me they want to launch a fund in the UK, the first structural question is almost always already answered: you are going to use a limited partnership. The LP structure accounts for the vast majority of venture capital and private equity funds established in this jurisdiction, and for good reason. It is tax-transparent, operationally flexible, and backed by over a century of legal precedent and service provider infrastructure.
The statutory foundation is the Limited Partnerships Act 1907 [1]. That is not a typo. The Act really is over a hundred years old. Despite its age, it has proven flexible enough to accommodate modern fund structures when combined with a well-drafted partnership agreement. Here is a walk-through of the mechanics, the regulatory treatment, and the practical considerations that matter when you are actually setting one up.
How the structure works
A limited partnership has two classes of partners. The general partner manages the fund and holds personal liability for fund obligations. The limited partners contribute capital but have no management authority, and their liability is capped at their capital contribution [2].
This separation is the entire point. The GP makes investment decisions, runs the fund, and bears the risk of personal exposure. The LPs provide capital and stay passive. Incentive alignment comes through the GP's own investment in the fund (usually 1-2% of commitments) and through carried interest, the performance fee that gives the GP a share of profits.
From a tax perspective, the LP is generally treated as a transparent vehicle. Investment income and capital gains flow through to each partner according to their ownership interest, rather than being taxed at the fund level [3]. This is a major advantage over corporate fund structures, where you get taxed once at the entity level and again when distributions reach investors.
English LP versus Scottish LP
Both are available. The choice between them comes down to a technical legal distinction that has practical consequences.
An English limited partnership does not have its own legal personality -- it is not a separate legal entity from its partners. A Scottish LP, by contrast, has separate legal personality under Scottish partnership law. This means a Scottish LP can hold assets, enter contracts, and sue or be sued in its own name.
For fund structures, the separate legal personality of a Scottish LP can simplify certain transactions -- particularly around property holding and contract execution. Some managers and their counsel prefer it for that reason. Others prefer English LPs because the absence of legal personality means clearer tax transparency in certain cross-border situations.
In practice, both work well for fund purposes. Your legal counsel will have a preference based on your specific circumstances, investor base, and investment strategy. I would not agonise over it.
Incorporation and registration
Forming a UK limited partnership is straightforward. You submit a Form LP5 to Companies House along with the partnership agreement and required documentation [4]. The registration fee is minimal, and the process typically completes within a few business days for standard applications.
The administrative burden after formation is also light. Partnership accounts must be maintained and filed with Companies House within nine months of year-end, and an annual confirmation statement is required to maintain the registration [4]. Compare that to the compliance overhead of, say, a Luxembourg RAIF or an Irish ICAV, and the UK LP looks very clean.
The partnership agreement
The partnership agreement is where the real work happens. It functions as the constitutional document governing the GP-LP relationship, and for a private capital fund it typically runs 100 to 150 pages. Every material aspect of the fund's operation is specified here: investment objectives, GP authority and obligations, LP rights and restrictions, capital call and distribution procedures, fee structures, expense allocation, governance mechanisms, advisory board composition, conflict of interest provisions, and side letter arrangements [1].
This document needs to be drafted carefully for several reasons.
Tax compliance. The partnership agreement must be structured to preserve the fund's tax-transparent status. Get this wrong and you can inadvertently create a taxable entity or trigger unexpected tax consequences for your LPs.
AIFM compatibility. The agreement needs to sit cleanly alongside AIFM regulatory requirements. The GP (or a designated external AIFM) is the regulated entity, and the agreement must clearly define who holds management authority, how investment decisions are made, and how regulatory obligations are discharged.
Carried interest provisions. With the April 2026 changes to carried interest taxation [5], the way carry is documented matters more than ever. The partnership agreement needs to specify carry calculation, allocation, distribution timing, and the average holding period conditions that determine whether carry qualifies for the 72.5% income reduction.
Side letters. Institutional LPs will negotiate side letters granting preferential terms -- fee discounts, co-investment rights, enhanced reporting, most-favoured-nation clauses. The LPA must accommodate these without creating inconsistencies or unintended consequences for other partners.
Regulatory overlay
The LP itself does not need separate regulatory registration as a fund vehicle. The regulatory requirements attach to the managing entity (the GP or a designated AIFM), which needs FCA authorisation or registration under the AIFM Regulations 2013 [6].
The regulatory obligations for the GP entity include everything that applies to AIFMs: fair treatment of investors, regular FCA reporting, investor protection requirements, valuation procedures, operational standards, record-keeping, compliance monitoring, and anti-money laundering procedures [6]. The specifics depend on which tier of the AIFM framework you sit in.
There has been increased regulatory attention to advisory boards and investor committees in limited partnerships. The FCA has flagged situations where advisory boards effectively control investment decisions that are nominally GP decisions [7]. This creates ambiguity about who actually bears management responsibility. The fix is clear documentation: advisory board authority should be explicitly consultative, not decisional, with the GP retaining unambiguous control over investment decisions.
Why the infrastructure matters
One advantage of UK limited partnerships that gets overlooked is the depth of service provider infrastructure built around them. Accounting firms, legal practices, fund administrators, custodians, and auditors have spent decades refining their processes for LP structures. This means standardised workflows, predictable costs, and service providers who can handle your fund without reinventing the wheel.
For an emerging manager, this matters more than you might think. When you choose a structure that your service providers handle every day, everything moves faster: the formation documents, the accounting setup, the investor onboarding, the first capital call. When you choose something unusual, you are paying for everyone to figure it out on your timeline.
Modernisation discussions
Industry consultations have floated proposals to modernise the 1907 Act: clarifying side letter procedures, accommodating digital subscription mechanisms, simplifying administrative processes, and addressing technical issues around successor partnerships and fund restructurings [1]. As of March 2026, no formal legislative changes have been enacted. Practitioners continue relying on the Act combined with detailed partnership agreements to get the job done.
I expect some modernisation will happen eventually, but the 1907 Act's track record speaks for itself. It has been flexible enough to support the entire UK private capital industry for over a hundred years. That is not nothing.
Practical tips for first-time managers
- Engage fund formation counsel early. The LPA is not a document you template. Your counsel needs to understand your strategy, investor base, and regulatory position before drafting.
- Budget properly for legal costs. A well-drafted LPA and PPM for a first fund will cost GBP 30,000 to 80,000 in legal fees depending on complexity. Do not cut corners here.
- Think about your GP entity structure. Many managers use a separate limited company as the GP to limit personal liability. The interplay between the GP company, the LP, and any carried interest vehicle needs careful planning.
- Plan for side letters from day one. Your LPA should anticipate side letter negotiations. Building in flexibility now is cheaper than amending later.
- Choose your administrator before you finalise the LPA. Your fund administrator needs to work within the operational framework the LPA creates. Getting them involved during drafting avoids costly rewrites.
