After a Build
What does an AI consultancy in London do?
An AI consultancy in London finds the admin your team repeats every week and builds the systems that do it for them. For most London service businesses that means enquiry replies, client and tenant emails, document chasing, invoice follow-up and reporting.
London raises the stakes on that admin. Staff cost more per hour than anywhere else in the UK, clients expect a same-day reply, and the market for AI help runs from boutiques to the big consultancies in the City. Most of the large firms are built for enterprises. Our work in London is with firms of 1 to 20 people: letting agents running portfolios from Zone 1 HMOs to outer-borough buy-to-lets, accountancy practices serving solo traders and small companies, and trades competing on how fast they reply.
We start with a fixed-fee diagnostic, then build one workflow at a time. The full UK service and fee list is on our AI consultancy page.
London sectors
Where do London businesses use AI first?
Letting agents and property managers
Tenant emails, maintenance triage, rent chasing and certificate renewals across portfolios that span several boroughs, each with its own licensing rules. The Renters' Rights Act changes added more tenant communication, not less.
Accountancy and bookkeeping practices
Document chasing, client onboarding and AML checks, plus the extra quarterly work Making Tax Digital for Income Tax brought for sole traders and landlords from April 2026.
Professional services firms
Solicitors, financial advisers, mortgage brokers and recruiters lose hours to client intake, identity documents and status updates that follow the same pattern on every file.
Trades covering London postcodes
Quotes that nobody follows up, jobs rescheduled around traffic and parking, and invoices chased from the van at the end of the day.

Do AI consultants in London charge more?
Many London consultancies price by the day, and City rates carry a premium. Our fees are fixed, published and the same anywhere in the UK: £499 for the AI Assessment, £1,500 for the AI Core Audit and £4,950 for an AI Core Build.
Single builds run from £1,500 for a no-code automation to £10,000 or more for an AI agent. Published UK rates in September 2026 ran from £90 an hour to production systems starting at £30,000, and we compared twelve agencies' prices in our guide to UK AI automation agencies.
AI consultancy or AI automation agency in London?
An AI automation agency in London usually quotes a build from your brief. A consultancy works out what to build first. We do both: a diagnostic that names your first automations, then a fixed-price build if you want us to do it.
If you already know the workflow you want automated, skip the diagnostic and ask for a quote on no-code automation.
AI training and workshops in London
Some teams need training more than a build. Our AI skills training is a one-day workshop, £1,500 to £3,500, built around your team's own emails, documents and reports rather than a generic ChatGPT demo.
Each person leaves with prompts written for their role and a clear rule for what goes into an AI tool and what stays out.
How do you choose an AI consultancy in London?
Pick the firm that fits your size and puts a price on the work. These checks sort most of the London market in one call:
- ✓They have worked with businesses your size. A firm built for City banks is a poor fit for a 10-person agency.
- ✓They give you a fixed price before work starts.
- ✓They map one workflow before they recommend a tool.
- ✓They can tell you where the automation will fail and where a person steps in.
- ✓They raise UK GDPR and client data on the first call.
Our longer guide covers how to choose an AI consultancy in London, including the questions to ask on the first call.
AI consultancy in London: questions
Is HeyBRB based in London?+
Yes. HeyBRB is a London-based AI consultancy. We work with businesses across Greater London and the rest of the UK, and most of the work runs on video calls, so it fits around your diary rather than a commute.
Do AI consultants in London charge more?+
Many do. We don't. Our fees are fixed and published, and they are the same in Camden as in Carlisle: £499 for the AI Assessment, £1,500 for the AI Core Audit and £4,950 for an AI Core Build.
Which London businesses do you work with?+
Service businesses with 1 to 20 staff: letting agents and property managers, accountancy and bookkeeping practices, solicitors, financial advisers, mortgage brokers, recruiters and trades. If you have 200 staff and need a machine-learning team, a larger London firm fits you better.
Can you run AI training for our London team?+
Yes. AI skills training is a one-day, hands-on workshop built around your team's real tasks, priced at £1,500 to £3,500 depending on team size. It runs live with your team and ends with a prompt library for each role.
Are you an AI consultancy or an AI automation agency?+
Both. We diagnose first, like a consultancy, then build and hand over the automations, like an agency. You can stop after the report and build it yourself if you prefer.
How quickly can we see results?+
The AI Assessment report arrives 5 business days after the call, with 5-7 automations ranked for your business. A single no-code automation is usually live 1-2 weeks after you approve it.
What happens if you don't find any savings?+
You get your money back. The AI Assessment is refunded in full if we find less than 5 hours a week of savings, and the AI Core Audit is refunded if we find less than 10 hours a week.
Start with the diagnostic
A 45-minute call, a report naming your first 5-7 automations in 5 business days, and your £499 back if we cannot find 5 hours a week. London teams of 5-20 start with the £1,500 AI Core Audit.
