The verdict in three sentences
For a 12-person firm that wants to win new engagements rather than just have a presence online, an agency pays for itself after the second or third small-business client won through the site. A freelancer remains a sound choice for a simple brochure site, provided the contract locks in code ownership, account access and maintenance. The real risk is not the purchase price, it is the abandoned website 18 months later when the contractor moves on or the regulatory wording goes out of date.
Freelancer or agency: what you are actually buying
In London the price gap mostly reflects how many skills are involved. A freelancer usually covers development and some design. An agency adds content strategy, local SEO, copywriting for service pages and a maintenance contract.
| Criterion (2026 order of magnitude) | Freelancer | Agency |
|---|---|---|
| Build budget | £1,800 to £3,000 | £7,000 to £12,000 |
| Typical day rate | £300 to £450 | £500 to £700 |
| Time to launch | 4 weeks | 8 to 10 weeks |
| Service pages written (tax, payroll, audit, start-ups) | 0 to 3, copy supplied by the firm | 8 to 15, copywriting included |
| Local SEO (City, Canary Wharf, Croydon, Richmond) | Basic tags | Location pages, Google profile, internal linking |
| Maintenance and security | Ad hoc | Contract at £70 to £220 per month |
| Continuity if the supplier leaves | High risk | Team, documentation, shared access |
The higher agency day rate covers project management, reviews and continuity. On a 15 to 20 day project, that explains most of the difference.
Professional rules, compliance and supplier risk
A firm regulated by ACCA or ICAEW must follow clear rules on publicity: accurate information, no disparaging comparisons, correct use of the professional body's designation and logo, firm registration details, and UK GDPR on contact forms. A badly configured site mainly creates reputational risk with the professional body and with clients.
| Checkpoint | Risk if missed | Who usually handles it |
|---|---|---|
| Firm details and regulator wording | Complaint, loss of credibility | Agency: included. Freelancer: you supply it |
| ICO-compliant cookie banner | Possible enforcement | Agency: included. Freelancer: varies |
| UK GDPR forms (purpose, retention) | Non-compliance | Agency: template ready. Freelancer: to be drafted |
| UK or EU hosting, backups | Data loss | Agency: contractual. Freelancer: often shared hosting |
| Ownership of code and accounts | Lock-in if the supplier leaves | Insist on it in both cases |
| Accessibility (WCAG basics) | Excluding some visitors | Agency: partial. Freelancer: rare |
With a freelancer, get it in writing: transfer of rights, admin access in the firm's name, domain and hosting in the firm's name, and an exit clause.
The calculation that settles it: the value of a small-business client
In 2026 a small-business client for bookkeeping, year-end accounts and tax returns is worth roughly £2,000 to £5,000 a year, often retained for 5 to 7 years. If the agency site brings 2 more clients a year than the freelancer site, that is £4,000 to £10,000 of extra recurring annual fees. The investment gap (£5,000 to £9,000) is recovered within one or two financial years.

Claire, partner at a 12-person accounting firm in London, compares two quotes: £2,400 from a freelancer and £10,000 from an agency with 10 service pages and maintenance at £110 per month. Over 3 years, total cost is £2,400 + estimated ad hoc maintenance of £1,300 = £3,700 for the freelancer, against £10,000 + £3,960 = £13,960 for the agency. Gap: £10,260. With 3 additional small-business clients over the period, each worth £3,500 a year, the firm brings in at least £10,500 in the first full year of those clients. The agency pays back in about 12 months.
FAQ
Can a freelancer deliver a site as effective as an agency's?
Yes, if the scope is clear and you provide the content. Expect 3 to 5 days of your own time writing copy, roughly £1,300 to £2,200 of partner time.
How long does an accounting firm website take?
About 4 weeks with a freelancer for a 5-page scope, 8 to 10 weeks with an agency that writes 10 to 15 pages and prepares local SEO.
What does maintenance cost for a firm website in 2026?
Between £70 and £220 per month depending on updates, backups and SEO monitoring. Without a contract, a one-off fix is often billed as half a day, so £150 to £350.
Do we need a client portal on the website?
Most firms already use the portal of their practice software. A simple link is enough and avoids £1,800 to £4,500 of custom development.
How do we avoid being stuck if the supplier disappears?
Keep the domain, hosting and admin accounts in the firm's name, and have the code delivered to a repository you own. It costs nothing and avoids a forced rebuild at £4,500 or more.
