How to grow a professional services firm in the UK

Why referrals stop being enough

Referral-led firms grow well while the partners' networks keep producing. The trouble starts when growth targets outrun those networks, or when a senior person leaves and their contacts go with them. Nothing in the firm was built to find new work on its own, so the pipeline is only as good as last year's relationships.

What to do when that flow thins is covered in our warm network and referrals are drying up.

Partners should not become salespeople

Partners win work in the room: they diagnose, advise and earn trust. Asking them to build lists and run sequences spends the firm's costliest time on the wrong job. The better split is that partners take the conversations, and an engine behind them fills the diary.

Many established firms also have a sales or business development lead who grew up inside the firm. They know the clients and the services, but they were never given a system: no tested message, no list and no reporting on what works. Building that system around them is often the better first move than replacing them.

What to build in the first months

• A target client profile: the clients the firm wants more of, and the ones it would turn away.
• One message per service line, in the client's words rather than the firm's.
• Proof clients can repeat: named examples, outcomes and short quotes.
• A referral ask with a set moment, such as the end of a project.
• Outreach to a checked list, run by the engine rather than the partners.
• Source tracking, so the firm knows which channel produced each new client.

The record behind it

Forte Growth's references for relationship-led firms come from Alper Yurder's career before Forte. At MindGym, where he was an early employee through its LSE IPO, he grew the financial-services vertical from £1M to £10M, moving it from relationship-led selling to a modern engine. The MindGym page has the detail.

As CRO at Witco, a French company that had grown at home through relationships, he took UK revenue from £0 to £1M, starting with a 90-day market-entry play. Both are his own results, not Forte Growth client engagements.

How Forte Growth works with service firms

Forte Growth builds and runs go to market and marketing for B2B startups and scale-ups, from strategy to sales. It starts with a pipeline audit inside the first month, then the go to market strategy, then the build, with the first outbound live inside three weeks. You own what it builds, and you either hand it to your team or keep Forte Growth running it. Where a firm already has marketers or an agency, Forte Growth directs them as one plan rather than replacing them. How the function works is on the outsourced marketing department page.

Common questions

How do professional services firms get clients beyond referrals?

By building an engine behind the relationships: a clear target client, one message per service line, proof clients can repeat, a set moment to ask for referrals and outreach that someone other than the partners runs. Track where each new client comes from, so the firm can see what works.

Should partners do business development?

Partners should take the conversations, because that is where they win work. Lists, outreach, content production and follow-up are better run by a function behind them, so partner time goes on clients and pitches.

Does outbound work for consultancies?

It can, when it is precise and backed by proof a buyer can check: named examples, outcomes and the partners' own thinking in public. Generic volume into a professional market can cost the firm more in reputation than it adds in meetings.

What does a marketing function cost for a services firm?

As a worked example, five UK marketing roles come to around £250,000 a year in London base salary, before employer National Insurance, pension, commission and recruitment fees. Not every firm needs all five. Forte Growth does not publish a price; its fee is agreed on the first call, against the scope.
