Companies House Changes for Limited Partnerships: ECCTA 2023 Part 2 Reforms to the Limited Partnerships Act 1907

If your property sits in a limited partnership, the compliance bargain you signed up for has gone. For decades the English LP was the workhorse of UK property finance precisely because it asked so little of you: register once, then carry on. Property-fund managers wrap institutional capital in it; joint-venture developers use it to pair a managing GP (often the developer's own corporate entity) with limited-partner investors; families hold tenanted property through a corporate GP with family-member limited partners. All three inherited the same baseline, the Limited Partnerships Act 1907, a short 17-section Victorian statute that demanded a light-touch initial registration and very little else.

That baseline is gone. The Economic Crime and Corporate Transparency Act 2023 Part 2 (commenced in phases from 2024 onwards) drags the LP into something close to the Companies Act 2006 regime: a UK registered office at an appropriate address, a registered email, an annual confirmation statement, general-partner identity verification, and a Companies House power to strike you off if you ignore any of it. Get this wrong and your fund roster goes public, your registered office fails the test, or worse, the registrar removes your LP from the register entirely. Here is what changed, what you now have to do, and why none of it touches the way your LP is taxed.

What did an LP owe before the ECCTA reforms?

The Limited Partnerships Act 1907 (LPA 1907) is a 17-section statute that creates the LP form, and it asked for almost nothing year to year:

• Initial registration via form LP5, listing the partnership name, the principal place of business, the partners (general and limited), and the partnership's general nature.
• Form LP6 to register changes in partners or capital. Triggered only when a change happened, not annually.
• No annual confirmation statement.
• No formal obligation to maintain a UK registered office (in many cases the principal place of business sufficed).
• No identity verification for general partners.
• No Companies House power to strike off non-compliant LPs.

This light-touch regime is the reason the English LP became the standard fund-vehicle wrapper in UK property finance: it provided the tax transparency of a partnership with limited liability for capital-only investors, at compliance cost materially below an equivalent UK limited company.

What did ECCTA 2023 Part 2 change for limited partnerships?

The Economic Crime and Corporate Transparency Act 2023 Part 2 substantively amends the LPA 1907. The five changes that will land on your desk:

Registered office at an appropriate address

Your LP must now have a UK registered office at an appropriate address (analogous to the CA 2006 s.28 appropriate-address rule for companies). A PO Box does not qualify. It has to be a physical location where documents delivered there can be expected to reach a person acting for the partnership, and where delivery can be acknowledged. If you already run the LP from your accountant's or solicitor's address, you are probably fine. If you have been using the family home or a virtual office (common for family-investment LPs), you will need to move the registered office to something that meets the standard.

Registered email address

You must give Companies House a registered email address for its notifications. A personal email is acceptable, but a dedicated partnership-domain inbox is the cleaner setup. This is the channel Companies House uses for statutory notices, including the start of any striking-off proceedings, so watch it. A notice you miss is still a notice served.

Annual confirmation statement

Your LP must file an annual confirmation statement listing the general partners, the limited partners, the capital contributions, and the nature of business. This is a Companies-Act-style filing analogous to the company confirmation statement at CA 2006 s.853A. It sits publicly on the Companies House register and builds a permanent record of who your partners are over time. If you run an institutional fund LP, this is the big one: your investor roster becomes public for the first time.

General partner identity verification

If you are an individual general partner (a natural person), you must verify your identity under the ECCTA Part 1 regime. Two routes: direct verification via GOV.UK One Login (free, for UK-resident individuals with standard ID documents), or ACSP-routed verification through a regulated formation agent or accountant. Where the general partner is a corporate entity (for example a Fund GP Ltd), the corporate GP itself does not verify identity; instead, its own directors verify under the companies-side ECCTA regime.

Companies House striking-off powers

Companies House can now strike non-compliant LPs from the register. Historically, once registered, an LP was effectively permanent absent a voluntary dissolution. Now the registrar can remove an LP that ignores the new regime. Lose your registered status and the damage ripples straight into your contracts, your banking, and the title to property the LP holds.

Are the ECCTA Part 2 reforms in force yet?

Partly, and the picture keeps moving. ECCTA Part 2 is being commenced in phases through separate statutory instruments made under the Act's commencement powers. As of the most recent updates to the Companies House campaign page (changestoukcompanylaw.campaign.gov.uk), some Part 2 provisions are in force, others sit in transitional windows for existing LPs, and others remain pending. What was true at the start of 2025 may not be true today.

If your LP already exists, you will usually get a transitional window of 6 to 18 months from the relevant commencement date to bring your registrations into line, though the exact window varies by provision. Treat the Companies House campaign page as the authoritative source and re-check the position at the moment you do your compliance review, not before.

Does ECCTA Part 2 change how your LP is taxed?

No, and that is the reassuring part. ECCTA Part 2 changes the compliance and transparency regime; it leaves tax treatment alone. LPs remain tax-transparent:

• Income tax. Each partner is taxed on their share of partnership trading or property profits per ITTOIA 2005 Part 9. The partnership files an SA800 partnership return; individual partners report their share on their personal SA returns.
• Capital gains tax. Partnership gains are allocated to partners under TCGA 1992 s.59 (fractional interest framework). Each partner's share of any gain is taxed in their own hands at their own CGT rate.
• SDLT. The Schedule 15 Finance Act 2003 partnership provisions are unchanged. Property transfers into and out of LPs continue to operate under the existing Sch 15 mechanics (covered on our partnership SDLT page).

The new annual confirmation statement is a Companies House filing, not a tax filing. The SA800 partnership return remains the operative annual tax filing. Do not conflate the two.

Three worked scenarios

Scenario 1: Established property-fund LP transition

Mawell Property Fund LP has been registered under LPA 1907 since 2018, with a corporate general partner (Mawell Fund GP Ltd) and twelve institutional limited partners. Pre-ECCTA the LP's compliance obligations consisted of the initial LP5 plus LP6 forms for any partner changes; there was no annual filing and no public confirmation of GPs or LPs beyond what was on the initial form.

Post-ECCTA Part 2, Mawell Fund LP must:

• Maintain a UK registered office at an appropriate address. The fund's office in the City is already compliant.
• Provide a registered email address. Configured to a fund-administration inbox monitored daily.
• File an annual confirmation statement listing all twelve LPs by name. This is the most visible change because the LP roster becomes public for the first time.
• Verify the identity of Mawell Fund GP Ltd's directors under ECCTA Part 1 (the corporate GP itself does not verify; its directors do).

The transitional window buys the fund time to prepare for that first confirmation. The institutional LPs have to be told their names are about to appear on the public register, and some investor-protection structures (nominee arrangements, beneficial-ownership chains) may need re-papering to manage the visibility.

Scenario 2: Family-investment LP holding tenanted property

Mr and Mrs Singh established Singh Family LP in 2015 as a family-investment vehicle holding four BTL flats. The structure: SinghCo Ltd (corporate GP, 100% Mr and Mrs Singh shareholders) plus Mr Singh, Mrs Singh, and adult son Vikram as limited partners (each with capital contribution).

Post-ECCTA Part 2 compliance:

• The LP must designate a UK registered office. The family-home address used historically must be replaced with an appropriate-address-compliant location, typically the accountant's service address.
• Annual confirmation statement listing all four partners (corporate GP plus three individual LPs).
• SinghCo Ltd's directors (Mr and Mrs Singh) must ID-verify under the companies-side ECCTA Part 1 regime; the corporate GP itself does not verify.
• The three individual LPs do not themselves verify identity under the LP-side regime because they are limited partners not general partners.

Tax treatment is unchanged. Mr Singh, Mrs Singh, and Vikram each report their share of partnership profit on their personal SA returns. SinghCo Ltd files its corporation tax return on its share. The Register of Overseas Entities does not apply because the LP is UK-domiciled.

The catch is the formality. The family has to run a tighter compliance posture than the old light-touch LPA 1907 baseline ever asked for. Families in this position sometimes look at converting to an LLP (different statute, established CA-style compliance) or to a limited company, if they can keep the same family-investment function with similar tax efficiency. Conversion is not automatic and triggers SDLT and CGT events, so weigh the trade-off carefully before you move.

Scenario 3: Overseas LP holding UK property (RoE interaction)

Lemberg Holdings LP is a Luxembourg-registered limited partnership owning two UK commercial properties (offices in central London). The GP is a Luxembourg holding company; the limited partners are a mix of EU institutional investors.

Two registrations now apply:

• The LP must register on Companies House's Register of Overseas Entities (RoE) under the Economic Crime (Transparency and Enforcement) Act 2022, because it is a non-UK entity holding UK land. The RoE registration includes the beneficial-ownership chain through to the underlying natural persons.
• Separately, if the LP carries out activities that bring it within ECCTA Part 2 scope (for example establishing a UK place of business or having a UK general partner), it may also fall under the LP-side compliance regime. Both registrations must be kept current; lapse of either has consequences.

The dual-regime overhead is one operational reason why some historic overseas-LP UK-property structures are being unwound. Onshoring to a UK limited company or a UK LP simplifies the compliance footprint at the cost of restructuring (with associated SDLT, CGT, and contractual implications). Each case needs its own analysis; some structures remain optimal as overseas LPs despite the dual registrations.

Your compliance checklist for an existing LP

1. Work out whether your LP is in operation, dormant, or a candidate for voluntary dissolution. ECCTA Part 2 compliance applies to in-operation LPs; a dormant LP may be better dissolved than re-papered.
2. Check that your current registered office meets the appropriate-address test. If it does not, relocate to a service address that does.
3. Set up the registered email address and make sure someone actually watches it.
4. List your general partners (natural persons) and confirm each has completed ECCTA Part 1 identity verification. New appointments need verifying before appointment; existing partners are typically subject to a retrospective verification window.
5. Prepare for your first annual confirmation statement. Work out what it needs (partner list, capital contributions, nature of business), assemble it, and file when the relevant provision commences for your LP.
6. Re-read your partnership agreement. Any clause that conflicts with the new regime (for example deliberate non-disclosure of partner identities) needs updating.
7. Talk to your investors. If your LP is institutional, the visibility shift needs flagging to them well before the first public confirmation filing.

If your structure is (or might become) something other than an LP, these go deeper:

• LLP property investment: the LLP under the LLPA 2000, a different statutory entity with a different compliance regime, which some family LPs convert into.
• Partnership SDLT Schedule 15: the SDLT mechanics when you move property into or out of any partnership (general partnership, LP, or LLP).
• Property partnership trading vs investment: the JV-LP structure for developer arrangements.
