The verdict in three sentences
In London, an international arbitration firm's website built by a legal-sector specialist agency is commonly priced at 35,000 to 120,000 GBP (2026 ballpark), before translation and photography. Kolonell's fixed grid covers the same editorial core from 2,300 GBP (Starter) to 6,900 GBP (Premium, the multilingual tier), with a project manager reachable on London time and launch in 3 to 6 weeks. The gap does not always cut the same way: it depends on your integrations, how many on-site workshops you expect, and how much weight the partnership puts on the brand.
What does an arbitration firm website cost in London in 2026?
The ranges below reflect typical London agency quotes and public agency rate pages. They vary widely with the agency's profile and the size of the firm.
| Provider | 2026 range (GBP) | Usual timeline | What is generally included |
|---|---|---|---|
| London-based freelance developer | 4,000 to 12,000 | 4 to 8 weeks | Adapted theme, 8 to 15 pages, little positioning work |
| Generalist web agency (City, Shoreditch) | 15,000 to 40,000 | 8 to 14 weeks | Bespoke design, CMS, testing |
| Legal-sector specialist agency | 35,000 to 120,000 | 12 to 24 weeks | Partner workshops, lawyer directory, integrations |
| Kolonell Starter | 2,300 | 3 to 4 weeks | Core editorial site, native copywriting |
| Kolonell Growth | 3,900 | 3 to 4 weeks | Richer templates: partner profiles, insights, sectors |
| Kolonell Premium | 6,900 | 4 to 6 weeks | Multilingual tier, languages set in the quote |
All three tiers include a project manager reachable in your time zone, native English or French copywriting, and 3 months of support after launch. Gated areas (data rooms, client portal), integrations with a conflict-check tool or a CRM, and custom applications are priced on quote. Tier details are on the international offer.
What the site must prove to general counsel and states
A general counsel, a board or a state agency looking for arbitration counsel does not read your site like a consumer. They quickly check partner reputation, the seats where the team has appeared, experience under the main institutional rules (ICC, LCIA, SIAC, HKIAC, ICSID, mentioned in general terms), working languages and sector experience.
| Page | What it must establish | Common mistake |
|---|---|---|
| Partner profiles | Background, roles (counsel, arbitrator), languages, admissions | Showing unverified rankings or awards |
| Arbitration practice | Types of disputes, rules the team has worked under | Describing matters covered by confidentiality |
| Sectors | Energy, construction, investment, insurance, according to your real work | A generic list of 20 sectors |
| Offices and seats | London, other offices, ability to act in Paris, Geneva or Singapore | Outdated addresses |
| Insights | Case notes, conference talks, dated articles | A blog frozen since 2023 |
| Regulatory information | SRA status, digital badge, complaints procedure, legal notices | Burying them in a hard-to-find PDF |
| Privacy and cookies | Policy aligned with UK GDPR and the Data Protection Act 2018, PECR consent | A banner that sets cookies before the visitor chooses |
On publicity, the Solicitors Regulation Authority (SRA) expects accurate, non-misleading communication, and most firms it regulates must display its digital badge. The ICO is the reference authority for personal data. On accessibility, the Equality Act 2010 makes WCAG 2.2 AA the sensible target. This is not legal advice: your compliance lead signs off the final copy.
In a related field, Kolonell built the website of TR Signing Group, a signing services company based in New Jersey: a professional services business where trust starts with clear, verifiable pages.
Hidden costs and the three-year total
The build price is only one line. Legal translation, partner photography and compliance review are added whatever the provider. The table compares a mid-sized firm over 36 months.
| Item | London specialist agency | Kolonell Premium |
|---|---|---|
| Website build | 60,000 GBP (mid-range) | 6,900 GBP |
| Legal translation (market assumption) | 3,000 GBP | 3,000 GBP |
| Partner photography (market assumption) | 2,500 GBP | 2,500 GBP |
| External compliance review (market assumption) | 1,500 GBP | 1,500 GBP |
| Maintenance over 33 months | 33 × 600 = 19,800 GBP (market assumption) | 33 × 300 = 9,900 GBP (market assumption, actual figure on quote) |
| Three-year total | 86,800 GBP | 23,800 GBP |
The first 3 months of support are included with Kolonell, hence 33 months of maintenance to budget. Beyond that, maintenance is priced on quote.
When a local agency is the better choice
A London agency makes sense if the partnership wants several in-person workshops at your offices, if the project is first a full rebrand (logo, stationery, signage), or if your procurement team requires a UK-established supplier. It also makes sense when the site must talk to your practice management system and conflict-check tool from day one.

Questions to ask any provider, local or remote:
- Who on your side speaks directly with the partners, and at what hours?
- Who owns the code, the content and the hosting accounts?
- How are lawyer profiles updated after a departure or a promotion?
- What accessibility audit is planned, and against which standard?
- What is explicitly out of scope and priced on quote?
Mini case study
Illustrative example: Harrowgate Lane LLP, a fictional London firm with 14 partners in arbitration and corporate law, receives a specialist agency quote of 52,000 GBP. It looks at Premium, the multilingual tier, in English, French and Spanish: 6,900 GBP, plus 2,800 GBP of legal translation (market assumption) and 1,900 GBP of photography (market assumption), for 11,600 GBP. The gap is 52,000 minus 11,600, or 40,400 GBP. Partner time is the same either way: 14 partners × 3 hours of sign-off = 42 hours to schedule.
FAQ
How much does an arbitration firm website cost in London in 2026?
Expect 4,000 to 12,000 GBP with a freelancer and 35,000 to 120,000 GBP with a specialist agency (2026 ballpark). Kolonell's grid runs from 2,300 GBP for Starter to 6,900 GBP for Premium.
Is Premium suitable for a multilingual site?
Yes, Premium is the multilingual tier, and the languages are set in the quote. Certified legal translation remains a third-party cost, around 1,000 to 1,500 GBP per language for a mid-sized site (market assumption).
Is a client portal or data room included?
No, gated areas, portals and integrations are priced on quote. Allow 2 to 4 extra weeks depending on complexity.
How long before launch?
3 to 4 weeks for Starter or Growth, 4 to 6 weeks for Premium. Partner sign-off often adds 1 to 2 weeks, whatever the provider.
Can we mention our matters and rankings?
Only what is public and accurate, with the clients' consent, since arbitration is often confidential. SRA rules require non-misleading publicity: your compliance team decides.
Let's scope your project. A Premium site in English, French and Spanish for a firm of 10 to 20 partners can be scoped in one call, with launch in 4 to 6 weeks. See the international offer or request a free quote: detailed reply within 48 hours.
