Hiring for Growth in the UK: Building Teams That Scale

When your business starts growing fast in the UK, hiring the wrong person can cost you more than just salary. It can slow down product launches, kill team morale, and even scare off investors. You’re not just filling roles-you’re building the engine that will carry you from £2M to £20M in revenue. And if your hiring process hasn’t changed since you were a team of five, you’re already falling behind.

Scaling isn’t about hiring more people-it’s about hiring the right kind of people

Most founders think scaling means hiring faster. That’s the trap. In 2024, 68% of UK startups that grew over 50% year-over-year actually hired slower than their slower-growing peers. Why? Because they focused on roles that moved the needle, not roles that looked good on an org chart.

At stage one, you need generalists-people who can handle sales, ops, and customer support because there’s no one else. But once you hit 10-15 employees, those jack-of-all-trades start to burn out. That’s when you need specialists. Not just any specialists. You need people who’ve been through this before. Someone who’s scaled a SaaS company from 10 to 100 in the UK knows exactly where the bottlenecks are. They don’t waste time figuring out how to set up payroll in the UK-they already did it three times.

Don’t hire for skills alone. Hire for adaptability. Ask candidates: “Tell me about a time you had to learn something completely new because the business needed it.” The answer tells you more than any CV ever could.

Build your hiring playbook before you need it

Most companies start writing their hiring process after they’ve already made three bad hires. Don’t wait. By the time you’re at 20 employees, you should have a documented system that includes:

• Clear role definitions with measurable outcomes (not just job descriptions)
• A standard interview loop with consistent questions
• A scoring rubric for each stage
• A reference-checking protocol that actually calls past managers

For example, if you’re hiring a marketing lead, don’t just ask, “How do you run campaigns?” Ask: “Walk me through how you’d increase qualified leads by 40% in six months with a £50k budget and no existing funnel.” Then watch how they structure their answer. Do they think in systems? Do they ask clarifying questions? Or do they just recite buzzwords?

Use tools like Greenhouse or Lever to track candidates through each stage. Don’t rely on spreadsheets or Slack threads. By the time you’re hiring 3-5 people a month, you’ll be drowning in chaos without a system.

Location matters-especially in the UK

The UK isn’t just London. And if you’re still assuming everyone wants to work in an office in the capital, you’re missing out on top talent-and saving serious cash.

Manchester, Leeds, Bristol, and Edinburgh all have thriving tech scenes with lower salary expectations than London. A senior developer in Manchester costs 22% less than one in London, according to 2025 data from Tech Nation. And remote-first policies mean you can hire from Scotland, Wales, or even Northern Ireland without losing quality.

But here’s the catch: you can’t just say “remote” and hope it works. You need a remote work policy that covers:

• Core hours for collaboration (e.g., 10am-3pm UK time)
• Equipment allowances (£500-£1,000 per hire)
• Annual team retreats (even if just a two-day meetup in Brighton)
• Clear expectations on response times and availability

Companies that nail remote work in the UK see 30% lower turnover than those that don’t. And they attract candidates who value flexibility over prestige.

Pay isn’t everything-but it’s still critical

UK salary benchmarks have shifted hard since 2023. A mid-level product manager in London now averages £68,000. In Birmingham, it’s £55,000. But here’s what most founders get wrong: they think they need to match London salaries everywhere.

You don’t. What you do need is transparency. Tell candidates exactly what you pay, and why. Use sites like Glassdoor, Payscale, and the Office for National Statistics to back up your numbers. If you offer £58,000 for a role in Leeds, explain: “We pay 10% below London to reflect lower living costs, but we give you £1,000 a year for professional development and 25 days’ holiday.”

Benefits matter more than ever. 73% of UK employees say flexible working and mental health support are more important than a 5% salary bump. Offer:

• Private healthcare with mental health coverage
• Learning stipends (£1,500/year)
• 4-day workweeks (trial-based)
• Parental leave that exceeds statutory minimums

These aren’t perks. They’re retention tools. And in a tight labour market, they’re the difference between hiring someone and losing them to a competitor who “just pays more.”

Culture isn’t a poster on the wall-it’s how you make decisions

You can’t hire culture. You build it through repeated actions. Every hiring decision you make sends a message.

If you hire someone who’s brilliant but toxic, you’re telling the team: “Results matter more than respect.” If you promote from within instead of bringing in outsiders, you’re saying: “Growth here is possible.”

Define your non-negotiables. For example:

• No one talks over others in meetings
• Feedback is given weekly, not just during reviews
• Failures are discussed openly, not hidden

Then screen for them. Ask: “Tell me about a time you gave feedback to someone who didn’t want to hear it.” Or: “What’s something you’ve learned from a mistake you made?” The answers will show you whether they fit-or will break your culture.

Don’t outsource your hiring to agencies unless you’re ready

Recruitment agencies can be helpful-but only if you’ve already defined what you need. Too many founders hand over a vague job description and expect an agency to magically find “the one.”

Agencies charge £3,000-£10,000 per hire. If you’re not clear on the role, outcomes, and culture fit, you’re just paying for noise.

Use agencies for hard-to-fill roles-like data engineers or compliance officers-but keep core leadership and customer-facing roles in-house. Your team needs to own the hiring process. Otherwise, they won’t feel invested in the people you bring in.

Track what actually matters

Stop counting how many people you hired this month. Start tracking:

• Time-to-fill (average days from job post to offer)
• Retention at 6 and 12 months
• Performance ratings at 90 days
• Manager satisfaction with new hires

One UK fintech company noticed their new sales hires were leaving after 8 months. They dug in-and found out the onboarding process took 6 weeks. That’s too long. They cut it to 2 weeks, added a buddy system, and retention jumped from 52% to 89%.

Measure these metrics every quarter. If your 6-month retention is below 75%, you’re hiring too fast or too loosely.

When to stop hiring-and what to do instead

Growth isn’t linear. Sometimes, the best move isn’t to hire more people. It’s to:

• Automate a repetitive task with AI tools (like Zapier or Make)
• Outsource accounting or legal work to a fractional expert
• Upgrade your tech stack so your team works faster
• Train existing staff to take on more responsibility

One SaaS company in Brighton hit £8M revenue but had 42 employees. They realized 12 of those roles were doing tasks that could be automated. They let go of 3 roles, retrained 5 others, and hired 1 senior engineer. Revenue went up 30% in six months. Headcount stayed the same.

Don’t confuse growth with headcount. Growth is about output per person. That’s what investors care about. That’s what your team cares about. That’s what your customers care about.

Final thought: Your next hire could make or break your next stage

Every hire you make between 10 and 100 employees shapes the company you become. A bad hire at 25 people can take 18 months to fix. A great one can unlock your next £5M in revenue.

Slow down. Get clear. Be intentional. The UK market is competitive-but it’s also full of talented people who want to build something real. You just have to be ready to find them.
