If you have been thinking about selling your dental practice, you will almost certainly have come across the term EBITDA. Brokers use it, buyers talk about it, and accountants calculate it — but for most practice principals it remains a piece of financial jargon that sits somewhere between confusing and intimidating.
This guide cuts through the noise. By the end, you will understand exactly what EBITDA means in the context of a dental practice sale, how it is calculated using realistic UK numbers, and why the figure your accountant produces may differ significantly from the one a buyer actually uses to value your business.
What Is EBITDA and Why Does It Matter for Dental Practice Sales?
EBITDA stands for Earnings Before Interest, Tax, Depreciation and Amortisation. Strip away the acronym and it is simply a measure of what your practice earns from its core operations before financing costs and accounting adjustments are applied.
Think of it this way: your profit-and-loss account includes a range of items that have nothing to do with how profitably your practice actually runs day to day. Interest on your practice loan reflects how you personally chose to finance the acquisition — not the underlying business performance. Depreciation on your dental chairs is an accounting entry, not cash leaving the building. EBITDA removes all of that noise and gets closer to the true cash-generative power of the practice.
Why does this matter for your sale price? Because buyers — whether that is a dental group, a private equity-backed consolidator, or an individual dentist — use EBITDA as the foundation for their valuation. They will apply a multiple to your EBITDA to arrive at what they are willing to pay. A practice generating £250,000 of EBITDA at a 5x multiple is worth £1.25 million. The same multiple applied to £200,000 of EBITDA produces a £1 million valuation. Understanding what drives your EBITDA is therefore directly equivalent to understanding what drives your sale price.
How EBITDA Is Calculated for a Dental Practice: A Worked Example
Let us walk through a realistic example using typical UK dental practice figures.
Annual revenue: £1,200,000
Less: direct costs (associates, lab fees, materials): −£480,000
Gross profit: £720,000
Less: overhead costs
- Practice manager and reception staff: −£95,000
- Dental nurses and support staff: −£110,000
- Premises costs (rent, rates, utilities): −£75,000
- Software, compliance, insurance: −£28,000
- Marketing and miscellaneous: −£22,000
Operating profit before principal’s remuneration: £390,000
Less: principal dentist salary (market rate replacement): −£140,000
EBITDA: £250,000
That final figure — £250,000 — is the number a buyer will then apply a multiple to. Note that the principal’s salary figure used here is not necessarily what you actually pay yourself. It is what it would cost to replace you clinically with an associate or salaried dentist. This distinction is central to the concept of normalised EBITDA, which we cover below.
For a deeper look at the overall methodology, see our detailed guide on how dental practices are valued.
Normalised vs Reported EBITDA — The Key Distinction
This is where many sellers are either pleasantly surprised or caught off guard.
Your reported EBITDA is what falls out of your management accounts or statutory accounts as-filed. Your normalised EBITDA — sometimes called adjusted EBITDA — is what a sophisticated buyer or broker will actually use. The difference lies in add-backs and deductions.
Common Add-Backs (Items Added Back to Increase EBITDA)
Principal’s salary or drawings above market replacement cost
If you pay yourself £220,000 per year but a replacement associate dentist would cost £140,000, the £80,000 difference is added back. The buyer is not purchasing your personal remuneration arrangements — they are buying the cash flow the business generates when staffed at market rates.
Personal car lease run through the practice
If the practice has been funding a personal vehicle via a finance agreement or operating lease, the cost is typically added back on the basis that a new owner would not replicate this expense.
Family members on the payroll above their market rate
If a spouse or family member draws a salary from the practice in excess of what the role would command on the open market, the excess is added back.
One-off professional fees
Legal costs relating to a lease renewal, a one-time compliance project, or costs associated with the sale itself are not recurring and will therefore be added back.
Common Deductions (Items Removed to Decrease EBITDA)
Covid grants and exceptional income
Any government support payments received during the pandemic — NHS top-up payments, furlough reimbursements, or other exceptional grants — are removed. A buyer is purchasing future earnings, not historic windfalls.
One-off cost savings
If you deferred staff pay reviews, capital maintenance, or training during a specific period, a buyer may normalise downwards to reflect the true ongoing cost base.
The net result of this normalisation process can move your EBITDA substantially in either direction. It is not unusual for a practice principal to believe their EBITDA is £180,000 and discover, after proper normalisation, that it is closer to £240,000 — adding £300,000 or more to the headline valuation at a 5x multiple.
NHS vs Private EBITDA — How Income Mix Affects the Multiple
Not all EBITDA is valued equally in the dental market. The composition of your revenue — specifically the balance between NHS contract income and private fee income — has a direct bearing on the multiple a buyer will apply.
NHS practices generate predictable, government-backed income through the UDA (Unit of Dental Activity) contract. This predictability is attractive, and NHS contract value is often assessed separately as a distinct asset. However, NHS contracts also come with exposure to workforce challenges in filling associate UDA targets and increasing regulatory scrutiny.
Private practices typically attract higher multiples when EBITDA margins are strong, because private revenue is less constrained by government policy and often more responsive to price increases and service expansion.
Mixed practices — the most common in the UK — are assessed on a blended basis.
As a rough guide:
- Predominantly NHS practice: 3x–5x EBITDA
- Mixed NHS/private: 4x–6x EBITDA
- Predominantly private: 5x–7x EBITDA
These are indicative ranges. The actual multiple depends on further factors including location, list size, number of surgeries, lease terms, and the presence of specialist services.
What EBITDA Multiples Are Typical for UK Dental Practices?
As of 2026, the typical EBITDA multiple range for UK dental practices sits between 3x and 7x, with the following broad segmentation:
- 3x–4x: Smaller single-surgery practices, predominantly NHS, challenging lease, rural or limited-demand location
- 4x–5x: Average mixed practice, stable income, reasonable margin, two to three surgeries
- 5x–6x: Strong mixed or private practice, growing revenue, solid team, good facilities
- 6x–7x+: High-margin private or specialist practice, strong patient base, multiple surgeries, scalable model
Corporate buyers and consolidators often pay at the higher end of the range for practices that fit their geographic rollout strategy or that add specialist capability to an existing cluster.

Why Your Accountant’s EBITDA Figure Might Not Be What a Buyer Uses
Your accountant prepares your accounts for a specific purpose: tax efficiency. That means structuring your remuneration to minimise your personal tax liability, running legitimate business expenses through the practice, and applying accounting standards that may bear little resemblance to how a buyer assesses cash generation.
The EBITDA that emerges from your statutory accounts is a starting point, not the end figure. A buyer’s financial due diligence team will reconstruct the accounts from scratch, applying normalisation adjustments as described above. The result can differ materially from what your accountant has shown you.
Working with a specialist dental practice broker means you have someone in your corner who can prepare a vendor-side normalised EBITDA schedule before you go to market. This gives you a defensible number, reduces surprises during due diligence, and puts you in a stronger negotiating position.
EBITDA and the Difference Between NHS Contract Value and Practice Goodwill
In an NHS dental practice, there are effectively two distinct assets being sold: the NHS contract (the UDA allocation) and the practice goodwill (the patient base, brand, systems, and team that generate income beyond the contract).
NHS contract value is typically expressed as a price-per-UDA, which fluctuates with market conditions. Goodwill is typically calculated using an EBITDA multiple applied to the normalised earnings of the practice as a whole. Most buyers will price the transaction as a single EBITDA-based valuation rather than splitting out contract and goodwill separately.
Three Things That Can Quickly Improve Your EBITDA Before Sale
1. Introduce or grow a patient membership plan
Recurring plan income — whether through Denplan, Practice Plan, or a bespoke in-house scheme — is highly valued by buyers. Even a modest increase in plan membership can meaningfully move your EBITDA multiple upward.
2. Review your cost base and remove non-commercial expenses
Work through your management accounts and identify any costs that a buyer would not replicate: personal expenses, inefficient supplier contracts, underutilised subscriptions. Removing £20,000 of non-commercial cost from your accounts adds £100,000 to your valuation at a 5x multiple.
3. Improve surgery utilisation
Buyers pay attention to revenue per surgery per day. Even partial improvement in the twelve months before sale will be reflected in a trailing EBITDA calculation.

Frequently Asked Questions
What is a good EBITDA margin for a dental practice?
A well-run UK dental practice typically achieves a normalised EBITDA margin of 20%–30% of total revenue. Predominantly private practices with efficient cost structures can reach 30%–35%. NHS-heavy practices often fall in the 18%–25% range due to the fixed UDA rate constraining revenue growth.
Is EBITDA the same as profit?
No. Net profit (as shown at the bottom of your accounts) deducts interest, tax, depreciation, and amortisation. EBITDA adds those items back to give a cleaner view of cash generation from operations. In a dental practice sale context, EBITDA is always the preferred metric.
How many years of EBITDA does a buyer look at?
Most buyers will review three years of accounts to establish a trend. A trailing twelve-month (TTM) EBITDA figure is commonly used as the basis for valuation. Where recent performance is significantly better than the historic average, buyers may weight the most recent year more heavily.
Can I improve my EBITDA before I sell?
Yes — and doing so is one of the most effective ways to increase your sale price. Improving surgery utilisation, growing plan membership, and removing non-commercial costs from the accounts can all move your normalised EBITDA meaningfully in the twelve to twenty-four months before going to market.
Does a dental practice with an NHS contract always sell for less than a private one?
Not necessarily. A large, well-run NHS practice with a significant UDA allocation and a strong associate team can attract a highly competitive valuation. The key variables are EBITDA margin, income stability, and the quality of the team and facilities — not NHS vs private status alone.
