The verdict in three sentences
For a mid-sized notary or private client practice in London, a website that genuinely works costs, as a 2026 order of magnitude, 7,000 to 13,000 GBP excluding VAT, plus an online booking module by matter type at 1,300 to 2,600 GBP. The return does not come from the design but from triaging enquiries upstream: probate, conveyancing, lasting powers of attorney or document notarisation arrive qualified, with the required documents listed, before the first meeting. Allow 8 to 10 weeks and a serious scoping phase on professional conduct rules and UK GDPR, or the project will drift.
What a notary practice website costs in London in 2026
London agencies typically charge around 700 GBP per day, sometimes more in the City and West End. The budget depends on how many journeys you need (one per matter type), how deep the calendar integration goes and how much legal content has to be written and checked.
| Item | 2026 range (GBP ex VAT) | Note |
|---|---|---|
| Discovery, sitemap, wireframes | 1,400 to 2,100 (2 to 3 days) | Workshops with notaries and paralegals |
| Site build (15 to 25 pages) | 3,500 to 6,300 | Pages per matter, team, fees transparency |
| Booking module by matter type | 1,300 to 2,600 | Questionnaire, slots, SMS or email reminders |
| Legal content writing | 900 to 2,100 | Reviewed by a partner |
| UK GDPR compliance (records, notices, cookies) | 450 to 1,000 | Data mapping of what you collect |
| Monthly maintenance | 70 to 130 per month | Updates, backups, monitoring |
The SRA Transparency Rules require solicitors offering probate or residential conveyancing to publish price information, and notaries follow the Notaries Practice Rules. A freelancer at 350 to 450 GBP per day can deliver for under 5,000 GBP, but rarely with a clean qualification questionnaire and complete data protection documentation.
The booking module: where the gain is made
Reception in a notary practice handles many calls that could be dealt with in writing: "what do you need for an apostille?", "how long does probate take?", "can you see me on Tuesday?". A booking module replaces these with a three-step journey: choose the matter, answer qualification questions, pick a slot with the right notary or fee earner.
| Function | Without module | With booking module |
|---|---|---|
| Booking | Phone, office hours | Online, 24/7 |
| Enquiry qualification | Done at first meeting | Done before, by questionnaire |
| Required documents list | Emailed afterwards | Shown and sent automatically |
| Allocation between staff | Manual by reception | Rules per matter type |
| Appointment reminders | Phone call or no-show | SMS or email the day before |
| Call volume at reception | Baseline 100 | 60 to 75 (25 to 40% fewer) |
One caution: the questionnaire must never give legal advice or a personalised fee quote. It routes, it does not conclude. General fee information can be shown, as transparency rules expect.
Conduct rules, ICO and security
Professional rules require accurate, non-misleading communication and no unsolicited approaches. On data, a probate enquiry already contains sensitive family information. You need UK or EU hosting, encrypted forms, a defined retention period, a clear privacy notice and registration with the ICO. Add restricted staff access and audit logs, and check whether your professional indemnity insurer has cyber requirements.

James, partner at an 18-person notary and private client practice in London, receives about 1,200 calls a month. Reception estimates 45% are about booking or document lists. With a booking module, the firm aims for 30% fewer calls, so 360 calls avoided per month. At 4 minutes per call, that frees 24 hours a month. At a loaded cost of about 30 GBP per hour for a receptionist, the saving is 720 GBP per month, around 8,600 GBP per year. On a total project of 12,000 GBP (site plus module), payback comes in under 17 months, before counting better-prepared files that cut follow-up appointments.
FAQ
How long does it take to launch a notary practice website?
Allow 8 to 10 weeks from the first workshop to go-live. Writing and partner review of legal content often takes 2 to 3 weeks on its own.
Can we display fees on the website?
Yes, and for probate and conveyancing the SRA Transparency Rules require it. Show general pricing and what is included; any personalised estimate happens in a consultation.
Does the booking module connect to our case management system?
Most modules sync with a shared calendar, which covers 80% of needs. A direct link to case management software usually needs custom work of 1,700 to 3,500 GBP depending on the vendor.
What maintenance budget should we plan?
Between 70 and 130 GBP per month for updates, backups and monitoring. Add a yearly review of privacy notices, about half a day.
Can Kolonell build this kind of site?
Yes. For a brochure site, our Growth tier sits between 1,830 and 3,050 EUR and Premium between 3,050 and 5,340 EUR; a complex booking module is a custom web application, priced on quote.
