Company Formation Services for New Businesses in the UK (2026 Guide)

Starting a limited company in the UK has never been more accessible on paper — yet the administrative layer sitting behind that single “incorporate now” button has never been more consequential. Between the Companies House fee increases that took effect on 1 February 2026, the phased rollout of mandatory identity verification under the Economic Crime and Corporate Transparency Act 2023 (ECCT Act), and the growing list of compliance obligations first-time founders are expected to understand from day one, choosing the right company formation agent is no longer a cosmetic decision. It is the difference between a clean, penalty-free start and months of chasing paperwork.

This guide breaks down exactly how UK company registration works in 2026, what has changed, and how the leading company formation services — Your Company Formations, ANNA Money, Companies Made Simple, and Online Filings — compare on price, compliance support, and post-incorporation service. It also covers the step-by-step incorporation process, the entities every new director needs to understand (PSC, SIC code, Articles of Association, UTR, ACSP), and the mistakes that most commonly delay a straightforward registration.

What a Company Formation Service Actually Does

A company formation service — sometimes called a formation agent or, in regulatory terms, an Authorised Corporate Service Provider (ACSP) — acts as an intermediary between a new business owner and Companies House, the UK’s registrar of companies. Rather than a founder navigating the Companies House WebFiling portal and the IN01 application unassisted, a formation agent packages the process: company name checks, preparation of the Memorandum of Association and Articles of Association, submission of statutory documents, provision of a registered office address, and — increasingly in 2026 — completion of identity verification on the founder’s behalf.

The ACSP designation matters more than most first-time directors realise. Since the ECCT Act reforms began taking effect, Companies House has required that anyone submitting filings on behalf of a company either be registered as an ACSP (subject to anti-money-laundering supervision) or that the individual director/PSC completes verification directly through the GOV.UK One Login service. A formation agent with genuine ACSP status can verify identity, file the incorporation, and handle ongoing submissions like the confirmation statement (CS01) without the founder needing a separate verification step for every filing — a meaningful time saving once you understand the deadlines involved.

The 2026 Rule Changes Every New Director Should Know

Two regulatory shifts landed in quick succession this year, and both directly affect the cost and process of forming a company.

1. Companies House fee increases (effective 1 February 2026). The digital incorporation fee doubled from £50 to £100, and the digital confirmation statement fee rose from £34 to £50 — a roughly 47% increase. Paper filings are considerably more expensive still, at £124 for incorporation and £110 for a confirmation statement, which is one of the clearest incentives to use a digital-first formation agent rather than filing on paper. Fees are charged based on the date a submission is made, so any application filed after 1 February 2026 attracts the new rate regardless of when the company year technically starts.

2. Mandatory identity verification for directors and PSCs. Under the ECCT Act, both directors and persons with significant control (PSCs) — anyone who owns more than 25% of shares or voting rights, or who otherwise exercises significant influence over a company — must now complete identity verification, and the two roles require separate verification submissions even when held by the same person. For a director who is also the sole PSC (the case for most solo founders), the verification window is 14 days starting the day after the company’s confirmation statement date. PSC-only individuals face an annual deadline tied to their birth month, while newly appointed PSCs have 14 days from the date they’re added to the register. Failing to verify in time isn’t a paperwork technicality — Companies House treats it as an offence that can carry a financial penalty.

These two changes together mean that a formation service’s value now extends well beyond “filling in a form for you.” The right provider tracks these deadlines, flags them before they’re missed, and — if ACSP-registered — can complete verification as part of the package rather than leaving a founder to navigate GOV.UK One Login alone.

Comparing the Leading UK Company Formation Services

Your Company Formations

Your Company Formations is one of the most widely reviewed formation agents in the UK, holding a 4.9/5 Google rating across more than 5,500 reviews and reporting over one million orders processed for clients globally. It is a certified Authorised Corporate Service Provider (ACSP), meaning identity verification for directors and PSCs is built into every package rather than sold as a bolt-on — a meaningful advantage given the 2026 verification deadlines described above.

Pricing is structured across three tiers, each on top of the standard £100 Companies House incorporation fee:

• Digital – from £2.48, a bare-bones option for founders who only need the legal filing completed.
• Fully Inclusive – from £48.48, adding a registered office address, digital document storage, and standard company secretarial extras.
• Entrepreneurs – from £149.99, the most comprehensive tier, aimed at founders who want banking introductions, compliance reminders, and ongoing support bundled in from day one.

Most incorporations are completed within three to six hours of submission, and the application itself typically takes around five minutes to complete online. The service includes a Central London registered office address (City Road, EC1), which gives home-based founders a professional trading address while keeping their residential details off the public register — a common concern now that PSC and director information is more visible than ever under transparency reforms. Post-formation, clients get 24/7 support, renewal and compliance reminders, up to £155 in cashback through partner banking offers, and access to a reported £100,000 worth of founder-focused perks and discounts from partner services. The company also plants one tree per company formed through its partnership with Ecologi, with a running total of more than 49,000 trees planted and over 600 tonnes of CO2e avoided — a small but genuine differentiator for environmentally conscious founders comparing otherwise similar agents.

For most new businesses — from solo consultancies to e-commerce startups — this combination of ACSP-backed verification, transparent tiered pricing, a genuine registered office service, and strong independently verified review volume makes it one of the safest default choices in the current regulatory environment.

ANNA Money

ANNA Money takes a different approach, positioning company formation as the entry point into a broader business banking and invoicing ecosystem rather than a standalone service. Founders who incorporate through ANNA typically do so because they want the registration process tied directly to a business current account, automated invoicing, receipt capture, and basic bookkeeping tools from the outset. This bundling appeals particularly to freelancers, sole-director consultancies, and e-commerce sellers who want to avoid stitching together a formation agent, a separate bank, and separate accounting software as three disconnected steps. The trade-off is that founders who already have a preferred business bank or accountant may find the bundled approach less flexible than a pure-play formation agent.

Companies Made Simple

Companies Made Simple is generally positioned toward budget-conscious founders who want a fast, no-frills registration without extensive add-ons. It’s a long-established name in the UK formation market and tends to suit founders who know exactly what they need — a Certificate of Incorporation, basic statutory documents, and nothing else — and who plan to handle registered office arrangements, banking, and ongoing compliance separately, often through their accountant. Given the 2026 fee increases, founders considering this route should confirm upfront whether identity verification support is included or charged as an extra, since not every budget-tier package bundles ACSP verification by default.

Online Filings

Online Filings is aimed squarely at experienced entrepreneurs and accountants who have been through the incorporation process before and want a self-service platform rather than guided support. It suits founders forming multiple companies, agencies incorporating on behalf of clients, or anyone comfortable navigating Articles of Association templates, SIC codes, and share structure decisions without hand-holding. It is generally not the right fit for a genuinely first-time founder who wants reassurance at each step, but it remains a solid, low-cost option for those who know the process.

How UK Company Registration Actually Works, Step by Step

Regardless of which formation agent you choose, every UK limited company registration follows the same underlying legal process governed by the Companies Act 2006:

1. Choose and check your company name. Companies House rejects names that are identical or too similar to an existing registered company, or that imply a connection to government or a regulated activity without permission.
2. Decide on your company type. Most new businesses register as private companies limited by shares, though some (charities, community projects) register as companies limited by guarantee instead.
3. Appoint at least one director and identify your PSCs. A PSC is anyone holding more than 25% of shares or voting rights, or who otherwise exercises significant control — most solo founders are both director and sole PSC.
4. Select a SIC code. The Standard Industrial Classification (SIC) code tells Companies House and HMRC what your company actually does; most businesses select at least one, and some select several if they operate across activities.
5. Prepare your Memorandum and Articles of Association. The Memorandum of Association is a short statement confirming the founding subscribers’ agreement to form the company; the Articles of Association set out the internal rules governing how the company is run — most founders use the standard “model articles” rather than drafting bespoke ones.
6. Provide a registered office address. This is the company’s official legal address, published on the public register — which is why many founders use a formation agent’s address rather than a home address.
7. Submit the IN01 application and pay the incorporation fee. As of February 2026, this is £100 for digital filing.
8. Receive your Certificate of Incorporation, which confirms your unique company number and legal existence.
9. Register for Corporation Tax with HMRC and obtain your company’s Unique Taxpayer Reference (UTR), generally within three months of starting to trade.
10. Consider VAT registration. This becomes mandatory once taxable turnover exceeds the current £90,000 threshold, though many businesses register voluntarily earlier for reclaim purposes.
11. Open a business bank account and, where applicable, complete director/PSC identity verification within the deadlines outlined by the ECCT Act.
12. File your confirmation statement annually (CS01), now £50 for digital filing, confirming that your registered details — including your PSC register and statutory registers — remain accurate.

How to Choose the Right Formation Service for Your Business

With pricing tiers, ACSP status, and bundled extras varying significantly between providers, the right choice depends on a handful of practical questions:

Do you need a registered office address? If you’re working from home and don’t want your residential address on the public register, prioritise a provider — like Your Company Formations — that includes this as standard rather than as a paid add-on.

Is ACSP-backed identity verification included? Given the 2026 verification deadlines and penalties for missing them, this has become one of the most important differentiators between formation agents rather than a nice-to-have.

Do you want banking and invoicing bundled in, or handled separately? Founders who want an all-in-one setup may prefer ANNA Money’s approach; those who already bank elsewhere may prefer a pure formation agent.

How much post-formation support do you expect to need? First-time founders generally benefit from compliance reminders, renewal notifications, and accessible customer support — areas where budget, self-service platforms like Online Filings intentionally offer less.

What does independent review volume tell you? A provider with thousands of verified reviews and a high satisfaction rating, rather than a handful of testimonials, is generally a safer signal of consistent service quality at scale.

Common Mistakes New Founders Make During Formation

Even with a good formation agent, a few recurring errors cause unnecessary delays or compliance risk: choosing a company name that’s rejected for being too similar to an existing one, forgetting to register for Corporation Tax within the required window after incorporation, missing the PSC or director identity verification deadline entirely because it wasn’t flagged by the agent used, assuming a registered office address and a trading address must be the same thing, and treating the confirmation statement as optional rather than an annual legal requirement with its own fee and deadline.

Frequently Asked Questions

What is an ACSP? An Authorised Corporate Service Provider is a business — typically an accountant, solicitor, or formation agent — registered with Companies House and supervised for anti-money-laundering purposes, authorised to verify identities and file on behalf of clients.

How long does UK company formation take? With a digital formation agent, incorporation is often completed within three to six hours of submitting a correct application; Companies House’s own same-day and standard services vary depending on filing method.

Do I need a registered office address if I work from home? You need a registered office address, but it doesn’t have to be your home. Using a formation agent’s address keeps your residential details off the public register.

What’s the difference between the Memorandum and Articles of Association? The Memorandum is the founding statement of intent to form the company; the Articles are the ongoing rulebook for how the company operates, including decision-making and shareholder rights.

Is using a formation agent better than registering directly with Companies House? Direct registration is cheaper on paper, but a formation agent adds registered office provision, ACSP-backed identity verification, and compliance reminders — value that has increased significantly since the 2026 fee and verification changes.

Final Thoughts

The right company formation service in 2026 is no longer just the cheapest way to get an IN01 filed — it’s the provider that keeps you compliant through the ECCT Act’s identity verification requirements, absorbs the administrative load of the Companies House fee changes, and gives you a professional registered office from day one. Your Company Formations currently combines all three with transparent tiered pricing and a strong independent review record, making it a solid starting point for comparison, alongside ANNA Money for founders who want banking bundled in, Companies Made Simple for a leaner budget approach, and Online Filings for experienced founders who prefer to self-serve.
