The UK remains one of the easiest major economies to set up a subsidiary in — open ownership rules, an internationally recognised legal system, English-language administration, and a relatively swift Companies House process. But the post-ECCTA landscape has added genuine compliance friction for inbound investors, particularly around identity verification and beneficial owner transparency. This is the playbook we run with foreign parents establishing a UK subsidiary in 2026.
Step 1: Choose the entity type
For most inbound investors the right answer is a private company limited by shares — the same workhorse UK Ltd used by domestic businesses, owned 100% by the foreign parent. Branches and UK establishments are an alternative but expose more of the parent's accounts and are less popular than they were a decade ago.
Step 2: Confirm the parent's documents
Before incorporating the subsidiary, gather:
- Certified copy of the parent's certificate of incorporation.
- Certified copy of the parent's constitutional documents.
- Recent good-standing certificate from the parent's home registry.
- Board resolution from the parent authorising the UK subsidiary formation and naming representatives.
- Identity documents for each director and PSC, ready for ACSP verification.
Step 3: Plan the share and PSC structure
If the parent will own 100%, the parent will be the sole PSC at the corporate level — but Companies House also requires tracing through to the ultimate beneficial owners. Identify them now: it is easier than during a Section 1083A query later.
Step 4: Choose directors carefully
Practical points:
- At least one natural-person director is required. Corporate directors are largely off the table after ECCTA, save for narrow exceptions.
- The director(s) must be willing and able to complete identity verification.
- For substance and bank account purposes, a UK-resident director (or at least one director who can attend UK bank meetings) helps enormously.
Many inbound subsidiaries appoint at least one UK-resident director sourced through their accountant or a professional services firm. We support clients with introductions where needed.
Step 5: Register the office and obtain the addresses
The UK subsidiary needs a registered office at an appropriate address. Most inbound clients use their accountant's office for the first 12–24 months while they establish UK premises. This also keeps the parent's address off the UK public register.
Step 6: Run the ACSP formation
The actual incorporation, when paperwork is in order, is straightforward — overnight processing at Companies House. Running it through an ACSP like PushDigits handles director and PSC verification simultaneously, which is the bottleneck for most inbound formations.
Step 7: Tax registrations
Once incorporated, register for:
- Corporation Tax within three months of becoming active.
- VAT if the subsidiary will exceed the threshold or wants voluntary registration to recover input VAT.
- PAYE if any UK staff will be employed.
If the subsidiary will primarily distribute the parent's products into the UK, plan VAT treatment carefully — different models (sale to subsidiary then to UK customer; sale via subsidiary as agent; direct sale with subsidiary as marketing entity) have meaningfully different VAT footprints.
Step 8: Bank account opening
Bank account opening is now the slowest part of inbound formation, often 4–8 weeks even after incorporation. UK banks scrutinise:
- The parent's beneficial ownership chain.
- The source of funds for the initial capital injection.
- The intended UK activities and customer base.
- The local directors' track records.
Strong introductions and a well-prepared business case shorten this materially. We pre-package the bank application with the formation paperwork to compress the timeline.
Step 9: Transfer pricing and intercompany agreements
From day one, every transaction between the UK subsidiary and the foreign parent should be supported by an intercompany agreement at arm's-length pricing. The UK transfer pricing rules now apply to medium-sized enterprises with reduced thresholds — assume they apply to you unless we tell you otherwise.
Step 10: The first 12 months
The subsidiary's first year will involve:
- First confirmation statement.
- First set of statutory accounts.
- First corporation tax return.
- Possibly the first VAT returns.
- Year-end intercompany reconciliations with the parent.
Building the right calendar and accounting platform now is much cheaper than reconstructing it later.
