Dental Practice Valuation and Acquisition: A Roadmap for Buyers and Sellers

Buying or selling a dental practice is the single largest financial transaction most dentists undertake. Valuations turn on multi-year EBITDA, goodwill multiples that vary by practice type and location, and the specific structure of the deal (asset purchase vs share purchase). The due diligence process separates competent buyers from naive ones; the financing landscape is dominated by specialist dental lenders (BDS Healthcare, Dental Director Finance, Hampshire Trust Bank, Allica) who price differently from generalist banks. And the eventual tax position for retiring principals, usually accessing Business Asset Disposal Relief, needs planning years before the sale.

This guide covers the practice transaction process end to end. Each section links to a detailed companion piece.

How dental practices are valued

The two main valuation methods used in UK dentistry:

EBITDA-multiple method

Calculate adjusted EBITDA (earnings before interest, tax, depreciation, amortisation, with adjustments for owner remuneration, non-recurring costs, related-party transactions). Apply a multiple appropriate to the practice type, size, location, and contract structure. Typical multiples in 2025-26:

• NHS-dominant suburban practice: 3-5x adjusted EBITDA.
• Mixed private/NHS practice in commuter belt: 5-7x adjusted EBITDA.
• High-end private practice in central London: 7-10x adjusted EBITDA.
• Specialty practice (orthodontic, oral surgery): 6-9x adjusted EBITDA.

Percentage-of-turnover method

Used as a sanity check or in markets where EBITDA is volatile. Typical bands:

• NHS practice: 60-80% of last completed year's NHS contract value.
• Mixed practice: 90-130% of total turnover.
• Private practice: 110-150% of total turnover.

Due diligence checklist

A buyer's due diligence covers:

1. Financial: 3 years of statutory accounts, management accounts to current month, NHS Compass reports, private revenue breakdown, lab cost analysis.
2. Clinical: GDC standing of all dentists, indemnity coverage, complaints history, clinical audit data.
3. CQC: registered manager, registration status, recent inspection outcome, any conditions.
4. Premises: lease (if leased) or freehold, dilapidations, planning consents.
5. Equipment: schedule of fixtures, age, replacement cycle, financing.
6. NHS contract: contract value, UDA delivery history, any underdelivery clawbacks.
7. Staff: contracts, holiday accruals, pension obligations, statutory entitlements.
8. Patient records: data quality, gap analysis, retention compliance.
9. Lab arrangements and supplier contracts.
10. Insurance coverage and any historic claims.
11. Legal: any active disputes, tribunal cases, regulatory issues.

Specialist dental lenders

UK dental finance is dominated by specialist lenders who understand the business model:

• Lloyds, NatWest, HSBC have dental teams within their commercial banking arms.
• BDS Healthcare, Dental Director Finance, Hampshire Trust Bank specialise in dental.
• Christie Finance and Capitol Finance act as brokers placing across multiple specialist lenders.
• Loan-to-value typically 65-85% on goodwill plus 100% on fit-out and equipment.
• Fixed and variable rate options; fixed often preferred for predictability of cash flow.
• Personal guarantees usually required from principals.

Asset purchase vs share purchase

For practices held in a limited company, the buyer can either acquire the assets (the trade) or the shares (the company itself):

Most UK dental sales are now share purchases of the practice company (rather than asset purchases of the trade) because of the NHS contract continuity and SDLT advantages. This has been the dominant pattern since around 2018.

CGT planning for retiring principals

A practice sale typically triggers Capital Gains Tax for the principal. Key reliefs and planning:

• Business Asset Disposal Relief (BADR): 14% CGT (rising to 18% over phased changes) on the first £1 million of qualifying gains.
• Qualifying conditions: at least 5% of ordinary share capital, held for at least 2 years, company a trading company throughout.
• For sales above the £1 million BADR cap: standard CGT rates apply on the excess (18% basic, 24% higher).
• Family Investment Companies (FICs) or trusts can multiply the £1 million cap across family members where structured early enough.
• Pension contributions in the years before sale absorb otherwise-taxable income at the most favourable rate available.
