Practice Valuations: How to Maximise the Value of Your Orthodontic Business

UK orthodontic practices are primarily valued using an EBITDA multiple methodology. A specialist valuations advisor calculates the practice’s maintainable EBITDA — the normalised annual earnings adjusted for the principal’s above-market drawings, one-off costs, and non-recurring items — and applies a market-derived multiple typically in the range of 5x to 8x for established private orthodontic practices. The resulting figure represents the enterprise value of the business. The multiple applied depends on the practice’s risk profile: practices with associate teams, systemised patient acquisition, and consistent financial performance achieve the upper end of the range; sole-principal practices with high personal dependency achieve the lower end.

EBITDA margin improvement is the single most powerful lever available to a principal seeking to maximise practice value before a sale. Because practice value is a multiple of EBITDA, every pound added to EBITDA margin adds a multiple of that pound to the enterprise value. A practice that improves its EBITDA from £150,000 to £200,000 through overhead reduction and staff cost management adds £50,000 in EBITDA, which at a 6x multiple adds £300,000 to the practice valuation. Reducing principal dependency is the second most impactful change — it protects the multiple from being discounted for key-man risk.

Three to five years before your intended sale date is the optimal preparation window. This allows sufficient time to: engage a specialist accountant to ensure three years of clean, well-presented accounts are available for due diligence; introduce and embed an associate to reduce principal dependency; implement and demonstrate a documented patient acquisition system; make any capital investment in equipment or premises that would otherwise become a buyer discount; and begin reducing personal expenses claimed through the business that obscure the true EBITDA figure. Practices that start preparing 12 months before sale consistently achieve lower valuations than those that start earlier.

The choice between a share sale and an asset sale has significant tax implications for both buyer and seller and should be decided with specialist legal and tax advice well before the sale process begins. Share sales transfer ownership of the practice company in its entirety, including its liabilities, and typically result in a more favourable tax position for the seller through Business Asset Disposal Relief. Asset sales transfer specific named assets and allow the buyer to choose what they acquire, creating a cleaner transaction for the buyer but a potentially less favourable tax outcome for the seller. The right structure depends on the practice’s corporate history, the buyer’s requirements, and the seller’s individual tax position — take advice from a NASDAL-registered dental specialist.
