Limited Partnerships After ECCTA: Two Years On, the Scottish LP Register Has Quietly Reset

The Economic Crime and Corporate Transparency Act 2023 (ECCTA) is usually discussed in the language of companies — director identity verification, the registrar's new query powers, the redrawn confirmation statement. But ECCTA also delivered the most significant overhaul of UK limited partnerships since the Limited Partnerships Act 1907 first put them on the statute book. Two years on from Royal Assent, with most of the partnership-specific provisions now commenced, the contours of a quietly reset register are beginning to emerge.

The shift matters disproportionately for Scottish limited partnerships (SLPs), which by 2016 had become the cause célèbre of UK corporate transparency campaigners. This piece looks at what the Act changed, how filings have moved in response, and what informed users of Companies House data should expect over the next reporting cycle.

What sets a Scottish LP apart

A limited partnership formed in England, Wales or Northern Ireland is, in legal terms, a curiously thin object: under the 1907 Act read with the Partnership Act 1890, it has no separate legal personality. It is a relationship between general and limited partners, with the general partner carrying unlimited liability and the limited partner restricted from management. Where the partnership owns assets, those assets are technically held by the partners; contracts are entered into by them as agents.

A Scottish limited partnership is structurally different. Scots law affords partnerships separate legal personality, meaning an SLP can hold title to property, sue and be sued, and enter into contracts in its own name. Combined with the partnership's tax transparency — partnership profits flow through to the partners for income or corporation tax purposes — the SLP became attractive in legitimate fund-structuring contexts (UK private equity has used SLPs for decades) and, to the embarrassment of the register, in laundering structures with bearer-share-like opacity.

A short history of the spike

A handful of investigations through 2014–2018 — most prominently the Russian Laundromat exposés, work by Transparency International UK, and reporting by The Herald and Bellingcat — drew attention to a dramatic, unexplained spike in SLP formations. Set against pre-2014 baseline volumes of a few hundred a year, registrations climbed sharply, peaking at a widely-cited figure of around 14,000 SLPs incorporated in 2016 alone, with the bulk routed through a small cluster of formation agents and registered to a handful of mailbox addresses in Edinburgh's New Town.

The first regulatory response was the Scottish Partnerships (Register of People with Significant Control) Regulations 2017, in force from 24 July 2017. They extended a PSC-equivalent regime to SLPs and qualifying Scottish general partnerships, requiring identification of any person with significant control and creating HMRC penalty exposure for non-disclosure. New SLP formations more than halved within a year, and have stayed below 2,000 annually ever since.

The table below summarises the regime as it has stood at three points in time.

What ECCTA actually did to the LP regime

Part 2 of ECCTA rewrites the 1907 Act in stages. The provisions of greatest practical impact, broadly in commencement order:

1. Registered office tied to the home jurisdiction. An LP's registered office must now sit in the part of the UK in which the partnership was registered — England & Wales, Scotland, or Northern Ireland. The address must be "appropriate" in the same sense as for companies, meaning that any document delivered there can be expected to come to the partnership's attention.
2. Principal place of business disclosure. General partners must notify the registrar of the partnership's principal place of business, and keep that disclosure current.
3. Identity verification. Every general partner — and, where the general partner is itself a corporate body, the managing officer — must verify their identity by the same process as company directors and registrable PSCs.
4. Annual confirmation statement. Existing LPs must file an annual confirmation restating registered office, partner details, PSC information, and the partnership's lawful purpose. Default is a criminal offence by every general partner.
5. Filings via ACSPs only after the transitional period. As with company filings, certain LP submissions will only be accepted from authorised corporate service providers supervised by an HMRC-listed AML supervisor.
6. Registrar power to strike off and dissolve. Where the registrar is satisfied that an LP is dissolved or has ceased to operate, it can publish notice in the Gazette and, after the prescribed period, deregister the partnership. Previously, the only route off the register was a partner-initiated dissolution.
7. Names regime. LPs are now subject to the same statutory list of restricted and sensitive names as companies, with a power for the registrar to require a change of name where one was registered improperly.

Existing LPs were given a six-month transitional window from the relevant commencement date to deliver the new information. That window is what is currently driving the most visible changes on the register.

What the register looks like now

Two patterns are worth noting. First, the SLP curve has now passed through three downward steps — the 2017 PSC reforms, the steady decline through 2019–2022 as anti-money-laundering enforcement bedded in, and a further drop visible across 2024 as transitional ECCTA filings rendered marginal LPs uneconomic to maintain. Second, the English and Welsh LP register, although larger and less politically charged, has been markedly stable across the period, consistent with its dominant use case in regulated fund management and joint-venture structuring.

The figure to watch in the registrar's next annual report is the count of LPs failing to deliver transitional information. Anecdotal evidence from formation agents suggests that dormant or partner-vacant SLPs from the 2014–2017 cohort make up the bulk of late and missing filings — exactly the population the legislation was designed to flush out.

Enforcement so far

Public enforcement under the new regime has been limited but visible. The registrar's first published quarterly insight under ECCTA reported a small number of LP-specific objections to address use, alongside wider company numbers, and HMRC continues to issue civil penalties for late or absent SLP PSC disclosures dating back to 2017. The substantive question is whether the registrar will use the new strike-off power proactively, or wait for partners to confirm dissolution. The early indication is the former: the structural appeal of an LP that survives without a working general partner is precisely what the new regime is intended to remove.

What due-diligence users should do differently

For investigators and KYC teams reading Companies House records on UK partnerships, three operational changes follow:

• Treat any LP with a registered office mismatch as a flag. A Scottish LP registered to an English service address — common before 2024 — is now a compliance breach, not a curiosity.
• Cross-check annual confirmation filings. An LP that has not filed an annual confirmation within the relevant 12-month window is, in 2026, materially overdue and arguably non-operational. Treat the absence as a working hypothesis of dormancy.
• Re-run partner-network searches. Identity verification reveals duplicates and aliases that the pre-2024 SLP register actively concealed. Any director-network mapping run before mid-2025 should be refreshed against the verified data set, particularly where SLPs sit in the chain.

The shape of the register in 2027

The most useful way to think about ECCTA's LP provisions is as a delayed completion of the 2015 PSC reforms. Companies were brought into a beneficial-ownership transparency regime more than a decade ago; partnerships have followed in stages, with ECCTA finally closing the loop on registered office, identity, and ongoing filing obligations. The next two reporting cycles — covering FY2025 and FY2026 — will tell us how much of the surviving SLP register is genuinely active business and how much is residual structural noise. Either way, by 2027 the register should look smaller, more accurate, and considerably less embarrassing than it did a decade earlier.
