London web design guide
By Web Design Studio LondonA London Ltd company has more options than any founder realises — online accountants from £38 a month, traditional City firms at £400, startup specialists who know SEIS and R&D credits, and Estonian jurisdiction for founders who want to defer tax entirely. Here is how to choose the right one for where you actually are.
Ask for advice
01
A standard owner-managed Ltd has five recurring obligations: annual accounts filed at Companies House, a Corporation Tax return filed with HMRC, quarterly VAT returns if you are registered, director payroll to process the salary portion of your remuneration, and a self-assessment tax return for each director. These five are the baseline — and not every service that markets itself as an accountant covers all five at its headline price.
In London the picture is sharper: traditional City and West End practices charge £250–£500 a month for this, while online accountants do the same statutory work for £38–£175. The difference is not quality of compliance — it is advisory access, responsiveness, and whether you get a dedicated named accountant or a shared team. The most common hidden charges across all providers are self-assessment billed separately (standard at Crunch Pro; £150 extra at Gorilla; included at QAccounting Complete), additional directors beyond the first, and the Companies House Confirmation Statement (£34 from Companies House direct; some accountants bundle it, others do not).

Ranked by overall value, transparency, and service quality for a standard London-based owner-managed Ltd in 2026:
£119+VAT/mo — one package, no tiers. 10% discount paid annually.
Single all-inclusive package at £119+VAT/mo — no tiers, no hidden extras. FreeAgent is included (worth £330/yr standalone), you get a dedicated accountant, unlimited support, quarterly business reviews, and one director self-assessment. The most transparent pricing model in the market. Highest Trustpilot score in the sector at 4.9/5 from over 2,100 reviews — a genuine and consistent signal, not a promotional claim. Fully remote-friendly: suited to London founders who want everything handled without ever visiting an office.
Best for: London contractors, consultants, and professional service Ltd companies who want complete certainty on price and scope
£72–£90+VAT/mo (Pro) | £109–£137+VAT/mo (Premium, self-assessment included)
The largest online accountancy brand in the UK for freelancers and small LTDs. Good proprietary invoicing and expenses software, a dedicated Crunch expert, and a well-known name that carries weight in London's freelance creative and tech communities. The Pro plan starts at £72+VAT/mo for six months then rises to £90+VAT/mo — but self-assessment is only included in Premium at £109–£137+VAT/mo. Most directors end up on Premium once they factor that in.
Best for: London freelancers, creative professionals, and small LTDs wanting a recognised brand and solid software without contractor-specific complexity
£50+VAT/mo (Essential) | £175+VAT/mo (Complete — unlimited IR35 contract reviews)
Specialist contractor accountant with genuine IR35 expertise — important in London where a large proportion of tech and finance contractors operate through agencies. Essential at £50+VAT/mo covers the basics with Xero; Complete at £175+VAT/mo adds unlimited IR35 contract reviews. Dual support model — admin manager for day-to-day, qualified accountant for complex questions.
Best for: London IT contractors, finance consultants, and CIS construction workers with meaningful IR35 exposure
From £60/mo (annual billing)
A newer entrant with genuinely broad inclusions at a competitive £60/mo billed annually. Annual accounts, Corporation Tax, Confirmation Statement, VAT, and payroll for up to five employees are all covered at base price — unusually comprehensive at this price point. Growing London presence, though fewer independent reviews than Crunch or Gorilla to assess service consistency.
Best for: Small London Ltd companies wanting comprehensive statutory coverage at a fair fixed price, without contractor or startup complexity
From £38+VAT/mo (dedicated accountant from £60+VAT/mo)
The most hands-off model in the market: photograph or post your receipts, and Mazuma handles the bookkeeping. No accounting software to learn. From £38+VAT/mo — the lowest price for an actual full service rather than software-only. Trade-off is limited real-time visibility and no capacity for complex tax planning, IR35, or startup advisory.
Best for: Small London Ltd companies and sole traders with straightforward finances who want to hand everything over and not think about it
Banking: £22.90–£59.90/mo + Accounting add-on: £24+VAT/mo
Business banking with an accounting add-on — best for pre-revenue London founders who want banking and basic bookkeeping in one place. Cheapest company formation fee in the UK at £19. The accounting product is software-assisted bookkeeping, not a full accountant: you will need a separate qualified accountant for Corporation Tax filing once you are trading at any real volume.
Best for: Pre-revenue London startups and micro-businesses wanting cheap formation and banking combined, before the business reaches a scale that needs a proper accountant
03
A startup raising angel investment or applying for Innovate UK grant funding needs an accountant who understands things a standard Ltd company never touches. Most online accountants (Crunch, Gorilla, Mazuma) do not handle the following as standard services — but for a London startup, these are not optional extras:
Lets early investors claim 50% income tax relief on investments up to £200,000 per company. For a London startup raising a pre-seed round from UK angel investors, SEIS advance assurance from HMRC — which your accountant applies for on your behalf — is often the difference between closing a round and not. Without it, many angels will not commit.
Best for: Startups raising their first angel or friends-and-family round in London
Qualifying London tech and science companies can recover 20–27% of eligible R&D costs from HMRC — either as a reduction in Corporation Tax or as a cash repayment if you are loss-making. A startup spending on software development, data science, AI, or product research almost certainly qualifies to some degree. The right accountant flags this proactively; a generalist waits for you to ask.
Best for: London tech startups spending on software development, AI, data science, or product research
Let early-stage London companies grant tax-efficient share options to employees — critical when you cannot compete on salary with larger companies. Setting up an EMI scheme requires HMRC registration and proper documentation. A startup-specialist accountant handles this as routine; a generalist often does not, or charges significantly extra.
Best for: London startups hiring technical or senior talent who expect equity as part of their compensation
Extends investment tax relief to larger raises: investors claim 30% income tax relief on investments up to £1 million per year (£2 million in knowledge-intensive companies). Relevant once you have outgrown SEIS — typically from your seed round onwards. EIS advance assurance is a standard ask from London angel syndicates and many institutional seed funds.
Best for: London startups raising a seed or Series A round from UK angels and early-stage funds
04
Estonia operates a unique corporate tax system popular with internationally mobile founders. An Estonian OÜ (private limited company) pays zero corporate tax on retained profits — tax is only triggered when profits are distributed as dividends, at which point a 20% rate applies. Any person worldwide can obtain Estonian e-Residency (a digital ID from the Estonian government, roughly €120–150) and register a company entirely online via partner services like Leapin or 1Office (€50–150/mo). The critical caveat for London founders follows below.
| UK Ltd Company | Estonian OÜ (e-Residency) | |
|---|---|---|
| Corporate tax on profits | 25% on profits over £250k (19% small profits) | 0% on retained profits — 20% only on dividends distributed |
| Formation | From £12 at Companies House (online, same day) | €120–150 state fee + partner service setup (1–3 days) |
| Ongoing management cost | £38–£175/mo (accountant) | €50–150/mo via e-Residency partner service |
| Physical presence required | No — fully remote | No — fully remote |
| UK tax resident founder caveat | N/A — this is a UK entity | HMRC central management and control test: if you run the company from London, HMRC may treat it as UK tax resident regardless of incorporation |
| Best for | Any founder based in the UK | Location-independent founders who are not UK tax resident, or EU-market-focused businesses with no UK substance |
| Worst for | Nothing — it is the default if you are in the UK | Founders who live and work in London and pay themselves a UK salary — the tax advantage does not apply |

The questions London founders ask most when choosing an accountant for their limited company — answered directly, with real prices.
How much should I pay for a Ltd company accountant in London?
Online providers handle full statutory compliance for £38–£175/month. Traditional City and West End practices charge £250–£500/month for the same legal obligations, with the premium covering a dedicated named accountant and proactive advisory. For a solo founder with straightforward finances and turnover under £150k, an online provider in the £75–£125/month range covers everything you are legally required to file.
What should be included in a standard Ltd company accountant package?
A complete package must cover annual accounts, Corporation Tax return, Companies House Confirmation Statement, director payroll, and VAT returns if you are registered. Self-assessment for the director is the single most commonly omitted item — ask about it explicitly before you sign. If any of these five are listed as add-ons, add the real annual cost before comparing quotes.
Do I need a London-based accountant or will an online provider do?
You do not need a local accountant for statutory compliance — HMRC and Companies House filings are identical regardless of where your accountant sits, and online providers handle them to the same standard. A local practice earns its premium if you need regular face-to-face advisory, have complex property or investment income, or your business operates in a regulated sector where sector knowledge matters.
What hidden charges should I look out for when comparing accountant quotes?
Three charges catch most London founders: self-assessment filed separately (typically £150–£200 extra), additional directors beyond the first (usually £20–£50/month each), and the Companies House Confirmation Statement (£34 if billed through the accountant rather than bundled). Some providers also cap payroll at a set number of payslips per month and charge above that threshold. Always ask for a written inclusions list and price out your actual situation, not the base-plan scenario shown on the pricing page.
What is the real difference between a cheap online accountant and a traditional practice?
Compliance quality is equivalent — both file the same forms to the same statutory deadlines. The substantive difference is access: a traditional practice gives you a named accountant who contacts you proactively, knows your business, and flags planning opportunities before year-end; online providers give you a portal, a shared support team, and reactive responses. For a simple owner-managed Ltd under £200k turnover with no complex tax affairs, the online model is usually sufficient and saves £2,000–£4,000 per year.
Can my Ltd company accountant also handle my personal self-assessment?
Most can, but many charge extra for it rather than including it in the monthly fee — this is the industry's most common upsell. Providers like QAccounting include personal self-assessment in their higher-tier plans; Crunch and Gorilla treat it as a billable add-on. If you draw dividends as well as salary, self-assessment is mandatory, so the cost is real — factor it into the total annual fee when comparing providers.

Your accountant handles Companies House registration, Corporation Tax, and makes sure you are paying yourself tax-efficiently from day one. The next question every new London Ltd faces is the same: where do potential clients check that you are real, credible, and worth calling?
In London the bar is high. Prospects in the City, Canary Wharf, or any professional services market expect a website that immediately signals competence. A referred lead will check your site before making contact. An enterprise client will verify it after the pitch. A startup raising investment will have every investor look it up before a second conversation. For businesses where credibility is the product — consulting, technology, finance, creative services — a dated, absent, or generic site is a silent objection that costs you work you will never know you lost.
The natural moment to sort your website is the same moment you sort your accountant: right at the start, before you are actively trying to win clients. We build websites for London-based limited companies — fixed prices, fast delivery, and no ongoing fees unless you want hosting or SEO. If that is the next item on your list, the easiest first step is a short conversation about what you need.
