Buying or Selling a Dental Practice: What Changes for Your Systems

Sooner or later, most practice owners face one of two big moves. You either buy a dental practice or you sell one. Buying or selling a dental practice is rarely just a property deal. It changes who holds your patient records, who owns the NHS contract, and which software runs your reception and your book on day one. This guide walks a UK practice owner or manager through what really changes for your systems when a practice moves from one pair of hands to another.

We are not solicitors or accountants, and this is not legal advice. Treat it as a practical map of the moving parts. Then get a specialist dental lawyer and an accountant on your team before you sign anything.

Buying or selling a dental practice: what actually changes hands

A dental practice sale usually takes one of two shapes. The first is an asset sale. The buyer purchases the goodwill, the equipment, and often the premises, but not the legal entity. The second is a share sale. The buyer buys the limited company that owns the practice, so the entity itself carries on.

The difference matters for your systems. In a share sale, contracts, registrations, and software licences often stay with the company. In an asset sale, almost everything has to be set up again in the buyer's name. That includes CQC registration, the NHS contract, bank mandates, and your practice management software account.

Knowing which type of deal you are doing tells you how much system work lies ahead. Ask this question early.

Dental practice valuation: what a buyer is really paying for

A dental practice valuation is not just the value of the chairs and the building. Most of the price is goodwill. Goodwill is the value of the patient base, the recurring income, and the reputation that comes with the name.

Valuers look at a few core things:

• Profitability. Often measured as EBITDA, which means earnings before interest, tax, depreciation and amortisation. In plain terms, the true annual profit.
• Income mix. A stable NHS contract, a healthy private list, and a growing membership plan each carry different risk and value.
• Recurring revenue. Patients on a membership plan and a well-run recall list point to predictable future income.
• Retention. How many patients come back, how full the book runs, and how little chair time sits empty.

Multiples move with the market, so do not treat any rule of thumb as fixed. The principle is steady. Clean, well-documented numbers raise the price. Messy records lower it, or scare buyers off entirely.

This is where your systems earn their keep before a sale even starts. A practice that can show its recall rate, its treatment plan acceptance, and its income split at the click of a button looks far more valuable than one that keeps it all in a shoebox and three spreadsheets.

Due diligence: the systems and records a buyer will inspect

Once a price is agreed, due diligence begins. This is the buyer checking that the practice is really what the seller says it is. Their solicitor and accountant will ask for a lot of paperwork.

Expect requests for:

• Patient numbers, active versus lapsed, and how they are recorded.
• NHS contract details, the UDA target, and delivery against that target.
• Income reports split by NHS, private, and plan.
• Staff contracts, associate agreements, and lab arrangements.
• CQC registration status and the last inspection outcome.
• Your dental practice due diligence software trail, meaning the reports and audit history your system can produce.

Good software makes this stage fast and calm. Poor record-keeping makes it slow and tense, and every gap gives the buyer a reason to renegotiate. If your data lives in one place and exports cleanly, due diligence stops being a threat.

Patient records: who becomes the data controller

Patient records are the beating heart of the deal. They are also personal data under UK GDPR, so they cannot just be handed over like a filing cabinet.

When a practice changes hands, the data controller usually changes too. The controller is the person or organisation that decides how patient data is used. On completion, the new owner becomes responsible for that data and for keeping it safe.

A few things must happen properly:

• Records transfer securely, not by unencrypted email or a loose USB stick.
• Patients are told, at the right time, that the practice has new ownership.
• Retention rules still apply. Dental records are kept for a long time, commonly cited as a minimum of around ten years for adults, and for children until their mid-twenties. Check the current NHS Records Management Code of Practice for the exact rule.
• The buyer registers as a data controller and reviews the privacy notice.

The Information Commissioner's Office sets the ground rules here. Read its guidance on data protection before completion, and see our fuller guide to GDPR for dental practices. Strong dental patient records software makes the handover cleaner, because everything is already structured, access-controlled, and exportable.

The NHS contract: it cannot simply be sold

Here is the part that surprises many first-time buyers. An NHS dental contract is not yours to sell like a car. It is an agreement between the provider and the NHS commissioner, now managed through Integrated Care Boards.

You cannot just transfer the contract to a new owner. In practice, the most common route is the partnership model. The buyer joins the existing contract as a partner. The seller then retires from it, sometimes after a short overlap. This keeps the UDA target and the contract intact.

This route needs the commissioner's agreement, and the rules are strict. Get it wrong and the contract can be lost, which wipes out a large slice of the practice value. Always use a solicitor who does dental deals for a living, and speak to your commissioner early.

Your job on the systems side is to prove delivery. The buyer will want to see UDA delivery against target, month by month. A system that tracks NHS activity clearly protects both sides during the sale. If you run a mixed book, our guide to managing NHS and private patients in one system shows how to keep the split clean.

CQC registration: a new provider must register

Every dental practice in England must be registered with the Care Quality Commission. Registration belongs to a legal entity, not to the building.

In an asset sale, the buyer is a new provider. They must register with the CQC before they can legally treat patients. This takes time, so it has to start well ahead of completion. In a share sale the company carries on, but you must still tell the CQC about changes such as a new registered manager.

Do not leave this late. A practice cannot open under new ownership without valid registration in place. Read the current rules on the CQC website, and use our CQC compliance checklist to prepare the evidence a fresh registration needs.

What happens to your practice management software

Your practice management system holds the diary, the records, the payments, and the recall list. When ownership changes, that account has to move to the new owner too.

There are three common paths:

1. The account transfers. In a share sale, the same company keeps the software, so the login and the data carry on. You update the billing and admin owner.
2. The buyer takes over the licence. The vendor re-papers the contract into the new owner's name. Data stays put, but responsibility shifts.
3. The buyer starts fresh and migrates. The old data is exported and imported into a new system. This is common when the buyer already runs another site on different software.

Whichever path you take, one thing is non-negotiable. The buyer needs full access to historical patient data. That means safe migration, not lost history. Our guide to switching dental software covers the export and import steps in detail.

A dental practice sale checklist for sellers

If you plan to sell, tidy your systems first. A buyer pays more for a practice that is easy to check. Use this dental practice sale checklist as a starting point.

• Clean the patient list. Merge duplicates and mark lapsed patients honestly.
• Make sure recalls are running and the reactivation list is up to date.
• Produce clear income reports, split by NHS, private, and plan.
• Confirm your UDA delivery against target is documented month by month.
• Check every associate, hygienist, and lab has a current written agreement.
• Gather your CQC evidence and your last inspection outcome.
• Confirm your data is exportable and your backups are encrypted.

Most of this lives inside your software. If your reports are messy, fix that months before you list, not the week the buyer's accountant calls.

Preparing to buy: getting your systems ready from day one

Buyers have their own systems checklist. The goal is simple. Be ready to treat patients safely and bill correctly on the first morning.

Before completion, line up your CQC registration, your NHS contract route, your data controller status, and your software account. If you are building a group, plan how the new site fits your multi-branch setup, so reporting stays consistent across locations. Confirm the deal fits your budget by checking pricing early, so software cost is never a last-minute surprise.

Frequently asked questions

Can I sell my NHS dental contract with the practice?

Not directly. An NHS contract is held with the commissioner, not owned outright. The common route is a partnership arrangement, where the buyer joins the contract and the seller then steps away. It needs the commissioner's approval, so involve a specialist dental solicitor early.

What happens to patient records when a practice is sold?

They transfer to the new owner, who becomes the data controller under UK GDPR. The transfer must be secure, patients should be informed, and retention rules still apply. Structured records software makes this handover far cleaner.

Does the buyer need to register with the CQC?

In an asset sale, yes. The new provider must register with the CQC before treating patients, and that process should start well before completion. In a share sale the existing registration often continues, but you must still notify the CQC of key changes.

How is a dental practice valued?

Most of the value is goodwill, driven by profit, income mix, and patient retention. Valuers often work from EBITDA, the practice's true annual profit. Clean, well-documented systems raise the figure a buyer will pay.

How long before completion should I sort out the software?

Start months ahead. Whether the account transfers, re-papers, or migrates, you want historical data safe and access ready on day one. Rushing a migration in the final week is how history gets lost.
