Buying and Selling a Dental Practice

Buying or selling a dental practice is not a normal business transaction. The thing being sold is a regulated healthcare business whose two most valuable assets — its care-regulator registration and, where it exists, its NHS contract — are the two things that cannot simply be handed over. This guide maps how these deals actually work in the UK: what drives value, what the buyer needs to check, how the regulatory transfer is done, and what a seller should do long before going to market.

Why dental deals are different

In most small-business sales, you agree a price, sign, and hand over the keys. In dentistry, a large part of the work sits in the regulatory plumbing underneath the deal. A dental practice’s value rests on its ability to keep treating patients the day after completion — and that ability depends on permissions that belong to the outgoing owner, not to the building or the patient list.

Two consequences follow, and almost every difficulty in a dental transaction traces back to one of them. First, the regulatory transfer runs on its own timetable, which is not the lawyers’ timetable and cannot be accelerated by wanting it more. Second, the deal structure is often chosen to solve a regulatory problem rather than a commercial one. An owner who understands that early makes far better decisions than one who discovers it at the point of exchange.

What a dental practice is actually worth

A dental practice is usually valued on its goodwill — the sustainable profit the business generates — plus its tangible assets. Beyond that, be sceptical of any rule of thumb. Multiples move with the state of the market, with the buyer type, and above all with the quality of the specific practice; a headline figure quoted at a conference or by a broker touting for instructions is not a valuation.

What is stable is the list of things that make a practice worth more or less than a superficially similar one:

• The profit that survives you. If the principal personally generates most of the clinical income, a buyer is purchasing a job rather than a business. Practices where the income is spread across an established associate and hygiene team command more, because the earnings continue after the seller leaves.
• Income mix and its durability. NHS, private fee-per-item and plan income behave differently under a new owner. Plan income with a stable membership base is attractive because it is recurring; income that depends on one departing clinician’s personal following is not.
• The team, and whether it stays. Associates, hygienists, therapists and an experienced practice manager are a substantial part of what is being bought. A practice with vacancies it cannot fill has a capacity problem the buyer inherits.
• The premises. Freehold, long leasehold and short leasehold are materially different propositions. A lease with little term left, an unfavourable rent review, or no security of tenure can quietly cap the value of an otherwise strong practice.
• Surgery capacity and condition. Unused surgeries represent headroom a buyer can grow into. Equipment near the end of its life represents capital expenditure they will have to fund.
• Compliance condition. A practice with orderly compliance evidence is cheaper and less risky to buy. Gaps show up in due diligence and are then priced in — or used to renegotiate.

The practical point for a seller is that most of these are improvable, but only with lead time. Value is built in the years before a sale, not in the negotiation. The same is true of the tax position: the relief that matters carries a two-year qualifying clock, which our guide to tax when selling a dental practice sets out.

For how valuations are actually constructed — the two methods in real use, the normalisation adjustment that recosts the principal’s own clinical work as an associate, and the tax position on disposal — see our detailed guide to dental practice valuation.

Buying a practice

Buying an existing practice, or starting a squat

There are two routes into ownership, and they suit different people. Buying an existing practice buys you immediate income: patients, staff, systems and cash flow from day one, at the cost of paying for goodwill and inheriting whatever problems come with it. Starting a squat practice — a new practice from scratch — means no goodwill payment and a practice built exactly to your specification, at the cost of building a patient base from zero while carrying full overheads.

A squat is not the cheap option, and it is a poor fit for anyone who needs income quickly. It requires capital to fit out and equip premises, a realistic runway before the practice covers its costs, and a genuine plan for attracting patients in a specific local market. It also requires the same regulatory registrations as any other practice, obtained before you can treat anyone. Where squats succeed, it is usually because the founder had a clear proposition and a location that was genuinely underserved — not simply because they avoided paying for goodwill.

Because new NHS contracts are not available on request, a squat is in practice a private-practice decision. Our guide to opening a squat dental practice covers that constraint, the planning and registration hurdles, and how the costs actually build up.

What to check before you buy

Due diligence in dentistry covers the usual commercial ground — accounts, contracts, premises, employment — plus a regulatory layer that a generalist adviser may not know to look for. Use dental-specialist legal and accountancy advice; this is the single most common piece of advice from people who have done it, and the most common regret from those who did not.

• The numbers behind the numbers. Not just turnover and profit, but where they come from: income by clinician, by treatment type and by income stream, over several years. One good year is not a trend — as our look at dental practice profit by the numbers shows, a single strong year can flatter a whole category — and income concentrated in the departing principal is a risk, not an asset.
• The NHS contract, if there is one. Its value, its activity requirements, its performance history, and whether the practice has been delivering or under-delivering. Under-delivery can have financial consequences that follow the contract — our guide to how the NHS dental contract works sets out the 96% performance threshold and what clawback actually recovers.
• Care-regulator standing. Current registration, the conditions attached to it, and the findings of the most recent inspection or assessment. Unresolved regulatory concerns become yours.
• Compliance evidence. Decontamination, radiation, safeguarding, information governance, staff training records. Absent evidence is a cost you will have to meet.
• The team’s contracts. Employment terms for staff, and associate agreements — including whether working practices actually match those agreements (see below), and what restrictive covenants exist.
• Premises and equipment. Title or lease terms, condition, compliance of the physical estate, the age and service history of equipment, and what the software and IT actually consist of.
• Patients. Active patient numbers rather than the number of records ever created, recall performance, and plan membership if applicable.

For the full working list — including whether TUPE applies to your deal structure, run-off cover for the seller’s historic liability, and the associate-status question that a standard agreement no longer settles — see our due diligence checklist for buying a dental practice.

The regulatory transfer: the part that governs the timetable

Care-regulator registration does not transfer

In England, CQC registration cannot be transferred from one provider to another. This is the point most first-time buyers underestimate. The incoming provider has to register in its own right, and the outgoing provider has to cancel its registration or remove the location from it, with the two applications coordinated so that there is no point at which the regulated activity is being carried on by an unregistered provider. The same requirement is triggered by a change of legal entity — an individual incorporating, or a partnership becoming a limited company — even where the people involved do not change at all.

Registration is not a formality and is not instant: it involves fitness checks on the provider and the registered manager. It needs to be started early and treated as the item that sets the completion date, rather than something to be handled once the commercial terms are settled. Scotland, Wales and Northern Ireland have their own regulators and their own registration processes, so confirm the position for your nation.

NHS contracts cannot simply be sold

Where a practice holds an NHS contract, that contract is frequently the most valuable single thing in the deal — and it is not an asset the seller can assign. GDS contracts prohibit assignment outright, so a straightforward sale of the contract is not possible. Transfers happen through recognised workarounds instead.

For unincorporated practices, the established mechanism is the partnership route: the buyer is added to the contract as a partner at completion, and the seller retires from the partnership afterwards, leaving the buyer holding the contract. For practices that have already incorporated, there is no equivalent right, and the contract holder must apply to the commissioner for consent to transfer — which is a request, not an entitlement.

Two things follow for anyone on either side of a deal. A seller should establish how their contract can actually be transferred before agreeing terms, because the answer depends on the structure they are already in. And a buyer should never assume that agreeing a price means the NHS income is secured; until the contract mechanism has been worked through with the commissioner, it is not.

Staff, associates and the people you inherit

Employed staff generally transfer with the business under TUPE, carrying their existing terms and continuity of employment, with obligations to inform and consult. This is not optional and needs planning into the timetable.

Associates are a separate question, and one that has become sharper. HMRC’s guidance at ESM4030 — under which an associate on a standard BDA or DPA agreement was treated as self-employed provided both sides kept to its terms — was withdrawn with effect from 6 April 2023. Status now turns on the general employment-status principles and the actual working arrangement rather than the existence of a standard-form contract. For a buyer, that makes associate arrangements a due-diligence item with a potential tax tail, not a box to tick: what matters is whether the day-to-day reality matches the paperwork. Our guide to dental practice management covers the employment-status question in more detail.

Selling a practice

For the mechanics — why the NHS contract and your company structure decide whether you are running an asset sale, a share sale or the partnership route, and what the law actually requires at each step — see our full guide to how to sell a dental practice.

Preparing, and how long it really takes

The sellers who achieve the best outcomes start preparing well before they intend to leave. Preparation means reducing the practice’s dependence on the departing principal, getting the compliance and financial records into a state that survives scrutiny, resolving anything that will show up in due diligence, and understanding how the NHS contract and registration will actually transfer given the structure the practice is in.

It also means being honest about the timetable. A dental sale runs at the pace of its slowest regulatory step, and those steps do not begin until the parties are far enough along commercially to trigger them. Sellers who plan to exit on a fixed date — a retirement, a relocation, a health reason — should work backwards generously.

Who buys practices, and what they want

The buyer landscape divides broadly into corporate and independent purchasers, and they do not want the same thing. Corporate and group buyers tend to value scale, transferable systems and profit that continues without the founder; they often propose structures where part of the consideration depends on future performance, and where the seller stays on clinically for a period. Independent buyers — often an associate buying their first practice, sometimes a neighbouring owner expanding — are usually buying a business they intend to run themselves, and may care more about fit and location than about maximising every point of value.

Neither is inherently better. What matters is that the structure of the offer is understood as well as its headline number. Deferred consideration, earn-outs and tie-in periods can all be reasonable, but they move risk onto the seller and their value depends on things that happen after control has passed.

Deal structure and tax

Sales are broadly structured as either an asset sale (the buyer acquires the trade and specified assets) or a share sale (the buyer acquires the company that owns the business, and with it the company’s history and liabilities). Which is available and which is preferable depends on how the practice is owned, how the NHS contract can be transferred, and the tax position of both sides. Buyers usually prefer asset sales for the clean break from past liabilities; sellers of incorporated practices often prefer share sales.

On tax, Business Asset Disposal Relief reduces the rate of capital gains tax on qualifying disposals, subject to a £1 million lifetime limit per individual. Its rate has been rising: disposals made on or after 6 April 2025 and before 6 April 2026 are charged at 14%, and disposals on or after 6 April 2026 at 18%. Anti-forestalling rules restrict attempts to lock in an earlier rate by timing contracts. Qualifying conditions are specific and the interaction with deal structure is exactly the kind of thing that is expensive to get wrong after the fact, so this is a question for an accountant while the deal is being shaped — not after it completes.

The four nations

Much of the commercial substance of a dental sale is the same across the UK, but the regulatory machinery is not. CQC registration applies in England only; Scotland, Wales and Northern Ireland each have their own regulator and registration route, and NHS arrangements differ correspondingly. If you are buying or selling outside England, confirm the registration and health-service contract position for your nation early — it is the part of the timetable most likely to differ from what general UK guidance describes.

Where to start

Whichever side of the transaction you are on, the sequence that avoids the most pain is the same:

1. Establish how the regulatory transfer will work for this specific practice, in its current legal structure, before agreeing commercial terms. The answer shapes the deal, not the other way round.
2. Assemble dental-specialist advisers — solicitor and accountant who do these transactions regularly. Generalist advice is where the avoidable problems come from.
3. Do the diligence that matches the risk. For a buyer, that means the NHS contract, registration standing and compliance evidence, not just the accounts.
4. Work the timetable backwards from the regulatory steps, and build in more room than feels necessary.
5. Take tax advice while the structure is still open, particularly given the rising BADR rate and its lifetime limit.
