The True Cost of Registering a UK Limited Company: 2026 Breakdown
There is no single answer to “how much does it cost to register a company in the UK” — because the total depends on how you register, which package you choose, and what you need included. The table below breaks down every route and every package available in 2026, so you can make an informed decision rather than choosing blind.
The most important thing to understand upfront: filing directly with Companies House costs £100 and gives you basic Model Articles. Using 1st Formations costs from £12.99, includes the Companies House fee, and gives you better documents. The agent route is cheaper and better — not a trade-off.
| Route / Package | Year 1 Cost | Year 2+ Ongoing | What’s Included | Best For |
|---|---|---|---|---|
| Companies House Direct ❌ | £100 | £34/year | Companies House registration only · Model Articles (generic, not SEIS-ready) · Certificate of Incorporation · No registered address · No error checking · ~8% rejection rate · Next working day processing | Nobody — more expensive than the agent route and you get less |
| 1st Formations — Simple ★ | £12.99 | £34/year | Companies House fee included · Model Articles · Digital Certificate · Electronic share certificates · Digital document pack · Same-day processing · Pre-submission error checking | Low-risk solo freelancers with zero investment plans; already have a registered address |
| 1st Formations — Privacy | £34.99 | ~£75/year | Everything in Simple + Central London registered office (yr 1) · Director service address · SAIL address · Confirmation statement yr 1 included · Statutory mail forwarding | Founders who don’t want their home address on the public Companies House register |
| 1st Formations — Smart ★★ RECOMMENDED | £52.99 | ~£75/year | Everything in Privacy + SEIS/EIS-optimised Articles of Association · Enhanced share structure · Subscriber shares allocation · Priority processing · 4 printed document copies | Any startup that might raise SEIS/EIS angel investment — do not skip SEIS-ready Articles |
| 1st Formations — Complete | £84.99 | ~£75/year | Everything in Smart + VAT registration · PAYE registration · Corporation Tax registration · Business bank account referral · 2 years of confirmation statement filing · Bound statutory book | Founders who want all HMRC registrations handled without doing it themselves |
| Solicitor / Law Firm | £500–£3,000+ | Ongoing if retained | Bespoke Articles · Complex share structures (drag-along, tag-along, vesting) · Multiple share classes · Investment agreement drafting · Series A-ready structuring | Only if you need bespoke Articles for complex share structures pre-incorporation |
All 1st Formations prices include the £100 Companies House incorporation fee (increased from £50 on 1 February 2026). Registered office and confirmation statement services included in year 1 for Privacy/Smart/Complete packages — renewal fees apply from year 2. Prices accurate as of March 2026 — verify at 1stformations.co.uk before purchasing.
1st Formations is an accredited formation agent that submits thousands of applications per month via Companies House’s specialist iXBRL software channel — the same channel used by solicitors and accountants. Their volume arrangement means they can absorb and reduce the £100 Companies House fee within their own service pricing. You pay less, receive more, and get same-day processing. It is not a gimmick — it is how the UK formation agent market works.
Companies House Official Fees 2026
Before choosing a formation route, it helps to understand the underlying Companies House fees. These are the government fees that every formation — whether DIY or via an agent — ultimately routes through:
| Transaction | Fee | Notes |
|---|---|---|
| Online incorporation (WebFiling) | £100 | Standard online route. Next working day processing. Increased from £50 to £100 on 1 February 2026. Included within 1st Formations packages — you don’t pay this separately. |
| Same-day online incorporation | £78 | Same-day direct via Companies House. 1st Formations’ standard service achieves same-day at £12.99 — much cheaper. |
| Postal incorporation | £71 | Paper filing. 8–10 working days. No valid reason to use this in 2026. |
| Annual Confirmation Statement (CS01) | £34/year | Mandatory for every UK Ltd. Must be filed within 14 days of your company’s anniversary. £34 whether you file yourself or via an agent. |
| Change of registered address (AD01) | Free | No Companies House fee. You can update your registered address at any time online. |
| Amending Articles of Association | £15–£34 | Companies House fee only. Solicitor fees to draft amended Articles: £500–£2,000+. This is the retrospective cost of not getting SEIS-ready Articles at incorporation. |
| Voluntary strike-off (dissolution) | £8 | Online voluntary strike-off (DS01). Must settle all debts and HMRC obligations before dissolving. |
Ongoing Annual Costs After Incorporation
The incorporation fee is a one-time cost. What most guides fail to explain clearly are the ongoing annual costs that every UK limited company faces from year 2 onwards. These are not optional — they are legal obligations. Here is the full picture:
📋 Mandatory Annual Obligations
Confirmation Statement (CS01)
£34/year — filed by you (DIY, 10 mins online)
£34.99 — filed via 1st Formations (incl. CH fee)
Corporation Tax Return (CT600)
£0 (HMRC filing is free)
Accountant to prepare & file: £300–£800/year
Annual accounts (Companies House)

🏢 Optional but Recommended Ongoing Costs

Hidden Costs Most UK Founders Miss
The Companies House fee is just the starting point. Here are the costs that catch founders off-guard in year 1 — and how to budget for them accurately:
⚠️ Amending Articles Post-Incorporation
If you incorporate with Model Articles (Simple Package or direct via Companies House) and later want to raise SEIS angel investment, you’ll need a solicitor to amend them. Cost: £500–£3,000. The Smart Package costs £52.99 and includes SEIS-ready Articles from day one. This is the most avoidable hidden cost in UK company formation.
⚠️ Late Corporation Tax Registration Fine
You must register for Corporation Tax with HMRC within 3 months of starting to trade. Missing this deadline triggers an automatic £100 fine. Handling this yourself via HMRC Online is free and takes 15 minutes. The Complete Package (£84.99) includes this registration — worth it if you’re likely to forget.
⚠️ Registered Office — Year 2 Renewal
The Privacy/Smart/Complete packages include a registered London office for year 1 only. Year 2 renewal costs from £39.99/year via 1st Formations. Most founders forget to budget for this. Once your home address has appeared on the CH register, it remains in historical records permanently — so the registered office service is worth maintaining.
✅ Business Bank Account — Don’t Use Your Personal Account
A UK limited company is a separate legal entity. Mixing personal and company funds creates legal and tax complications. Most digital business accounts (Starling, Tide, Monzo Business) offer free or £5–£12/month plans. For multi-currency or non-UK resident directors, Airwallex is the strongest option — free to open, competitive FX rates. See our Best Business Bank Accounts UK 2026 guide.
📊 Accounting Software — Not Optional
Making Tax Digital (MTD) means you’ll need compliant software from day one. Xero starts at £15/month (Starter plan) and handles VAT, payroll, and bank reconciliation. Free options (Wave) exist but are not MTD-compliant. Budget £180–£360/year for accounting software as a baseline cost of running a UK Ltd.
✅ VAT Registration — Free (Do It Yourself)
VAT registration is mandatory when turnover exceeds £90,000/year. Voluntary registration is possible below that threshold. VAT registration via HMRC Online is free. 1st Formations charges £39.99 to do it for you — only pay this if you genuinely lack confidence doing it yourself, since it’s a 20-minute online form.
Total Year-1 Cost by Founder Type
The “right” package depends on your situation. Here is a realistic total year-1 cost for the three most common UK founder profiles:
🧑💻 Freelancer / Sole Director
No SEIS plans. UK-based. Working from home.
1st Formations Privacy Package — £34.99
Business bank account (Starling/Tide) — £0
Xero Starter (12 months) — £180
CT/PAYE registration (DIY, free) — £0
Accountant (year-end, basic) — £300
Year 1 Total: ~£515
🚀 Startup Founder (SEIS Plans)
Planning to raise angel investment. UK-based.
1st Formations Smart Package ★ — £52.99
Airwallex business account — £0
Xero Starter (12 months) — £180
CT/PAYE registration (DIY) — £0
Accountant (year-end + SEIS advice) — £600
Year 1 Total: ~£833
Compare: solicitor SEIS Articles alone = £500–£3,000. Smart Package is the only sensible choice.
🌍 Non-UK Resident Founder
Incorporating UK Ltd from overseas.
1st Formations Smart Package — £52.99
Airwallex multi-currency account — £0
Xero (12 months) — £180
Deel (director payroll, if needed) — From £49/month
UK accountant (CT residency advice) — £500+
Year 1 Total: ~£1,320+
DIY vs Formation Agent: True Cost Comparison
The “just file it yourself” argument sounds logical — until you work out the actual numbers. Here is the honest comparison:
| Factor | DIY via Companies House | 1st Formations Smart (£52.99) ★ |
|---|---|---|
| Year 1 registration cost | £100 | £52.99 (all-in) |
| Registered address (yr 1) | You provide (home address exposed) | Central London — included ✅ |
| Articles of Association | Model (not SEIS-ready) | SEIS/EIS-optimised — included ✅ |
| Error checking | None — ~8% rejection rate | Pre-checked — near-zero rejection ✅ |
| Processing speed | Next working day | 3–6 hours same-day ✅ |
| Cost if SEIS fix needed later | £500–£3,000 solicitor fee | £0 — already SEIS-ready ✅ |
| True worst-case year-1 cost | £100 + £3,000 fix = £3,100 | £52.99 — nothing to fix ✅ |

Frequently Asked Questions: UK Company Registration Costs 2026
How much does it cost to register a limited company in the UK in 2026?
The cheapest route is £12.99 via 1st Formations — that price includes the £100 Companies House incorporation fee (which increased from £50 on 1 February 2026). Filing directly with Companies House costs £100. 1st Formations’ recommended Smart Package (SEIS-ready Articles + registered London office) costs £52.99. Solicitor-drafted incorporation starts at £500 and is only necessary for complex share structures. There is no scenario in 2026 where filing directly with Companies House is the right choice over using 1st Formations.
Why is 1st Formations cheaper than Companies House direct?
1st Formations is an accredited formation agent that submits applications in bulk via Companies House’s iXBRL software channel. Their volume arrangement allows them to offer incorporation at below-government-fee pricing as part of their service packages. The £100 Companies House fee is bundled within 1st Formations’ pricing — you pay one price, get a superior product, and the agent handles the Companies House submission on your behalf.
What is the ongoing annual cost of running a UK limited company?
From year 2, the minimum mandatory costs are: (1) Confirmation Statement — £34/year if you file yourself, £34.99 if via 1st Formations; (2) Registered office renewal — from £39.99/year if you’re using 1st Formations’ address. That’s a minimum of £74/year in regulatory costs. Add accounting software (£180+/year) and an accountant for year-end accounts (£300–£800+), and the realistic ongoing cost of running a lean UK Ltd is £500–£1,200/year.
Can I register a UK limited company for free?
No. Every UK company registration requires payment of the Companies House incorporation fee — £100 for online filing via WebFiling (increased from £50 on 1 February 2026), or £71 by post. There is no free route. However, 1st Formations bundles this fee within their £12.99 Simple Package, so the agent route is cheaper all-in than filing direct. Any service advertising “free company formation” is typically an upsell model where the initial incorporation is subsidised by mandatory ongoing service fees.
Do I need to pay for SEIS-ready Articles of Association separately?
Not with 1st Formations. SEIS/EIS-optimised Articles are included in the Smart Package (£52.99) and Complete Package (£84.99). If you’ve already incorporated with standard Model Articles and need to amend them for SEIS eligibility, you’ll need a solicitor — typically £500–£3,000. This is the single most important reason to choose the Smart Package at the point of incorporation rather than paying £12.99 now and potentially thousands later.
How much does it cost to register a company as a non-resident?
The formation cost is the same as for UK residents — from £12.99 via 1st Formations (Smart Package recommended at £52.99, as the registered address is mandatory for non-residents). Additional costs for non-residents: a UK business bank account — traditional banks are difficult; use Airwallex which supports non-resident directors for free. If taking a salary, Deel manages international payroll compliantly. A UK-based accountant to advise on Corporation Tax residency rules is strongly recommended — budget £500–£800 for that first-year consultation.
What does the Companies House confirmation statement cost, and is it compulsory?
Yes — it is mandatory. Every UK limited company must file a Confirmation Statement once per year with Companies House. The Companies House filing fee is £34, whether you file yourself online or through an agent. Filing yourself takes 10–15 minutes via Companies House WebFiling. Using 1st Formations’ service costs £34.99. Late filing can result in a £150 automatic fine and ultimately compulsory strike-off. Put it in your calendar for 14 days before your company’s incorporation anniversary each year.
What’s the cheapest way to register a limited company in the UK in 2026?
The cheapest all-in route is the 1st Formations Simple Package at £12.99 — which includes the £100 Companies House fee. However, “cheapest” and “best value” are different things: the Simple Package uses Model Articles that are not SEIS-ready. If there is any chance you’ll raise angel investment, the Smart Package at £52.99 is both the best-value and the lowest-risk choice. Filing direct with Companies House at £100 is the most expensive and least-equipped option available. Full 1st Formations review: 1st Formations Review UK 2026 →
