Smart Leasing vs Buying Dental Equipment: How to Protect Cash Flow Without Stalling Practice Growth

You’re scaling your practice. New chairs, scanners, even a second site — and you’re wondering:

Should I lease it… or buy it outright?

From 80+ dental practices I’ve worked with, this is one of the biggest cash flow forks in the road. Get it right, and you preserve liquidity, optionality, and sleep. Get it wrong — and your growth strangles your oxygen.

Leasing isn’t a weakness. Buying isn’t always wise. The key is knowing when each protects cash flow — and when it puts it at risk.

Why You Can Trust This

As a Chartered Accountant and Dental CFO, I’ve advised UK dental owners through every kind of scale-up — from leasing their first scanner to acquiring freeholds across three sites.

I’ve modelled both sides. And I’ve seen cash flow wrecked by upfront ego buys — and rescued by strategic leases.

TL;DR — Before You Lease or Buy:

• Buying gives ownership — but hits your working capital.
• Leasing protects cash flow — but can become a cost trap.
• The right choice depends on cash burn rate, profit margins, and future flexibility.
• Run the forecast first. Decide second.

Real-World Trap: The Scanner That Crushed Liquidity

In 2022, a £940K private principal bought a £29K intraoral scanner outright — to “save interest.”

But they didn’t forecast the 6-month lag in private ortho treatments ramping up.

Result? They dropped below £5K buffer for 2 months, deferred associate pay, and paused Google Ads that were generating £19K/month of new treatment.

💬 Lesson: Buying saves money on paper. Leasing saves liquidity in real life.

What’s the Cash Flow Impact of Leasing vs Buying?

Here’s how each model affects your cash position, risk, and flexibility:

Tip: Use leasing to preserve ECFTI™ when growth is aggressive, and reserve capital for high-return marketing or staffing moves.

When Does Leasing Help Protect Liquidity During Growth?

I recommend leasing in 3 specific scale-up scenarios:

Use Leasing When:

1. You’re launching a second site and need buffer for recruitment, marketing, or patient ramp-up delays.
2. Your ECFTI™ is under £7.5K/month, and one big buy would choke cash flow.
3. You’re investing in treatments with delayed revenue (e.g., aligners, implants with consult-to-fit lag).

Practitioner Insight: One mixed practice in Manchester leased 2 new chairs for £489/month each during expansion. That freed £18K they used for rebranding, local PPC ads, and a hygienist hire. New revenue: £9.7K/month by month 4.

💬 Truth: Liquidity isn’t about what’s cheapest. It’s about what keeps you breathing.

How Do I Decide What to Lease vs What to Own?

Rule of Thumb: If it has high upfront cost, low resale, and delayed ROI — lease it.

Before You Finance Your Next Chair… There’s a Bigger Cash Trap Most Growing Clinics Miss

Leasing vs buying is only one part of the cash-flow equation. The real strain often shows up months later — when HMRC collects on the growth you created.

Every new chair, scanner, or site expansion increases profit on paper… but tax follows on a lag. And most growing clinics forecast the asset — but forget the tax that arrives 6–18 months afterward.

That’s how practices end up cash-tight even when production is rising.

Final Words: Liquidity is Your Lifeline

In growth mode, every decision touches cash.

Leasing doesn’t mean you’re not profitable. It means you’re thinking ahead.

Buying isn’t always strength. It can be a blind spot if it costs you flow.

From what I’ve seen across dozens of practice scale-ups — the winners aren’t the ones who “own more.” They’re the ones who breathe better while they grow.
