Buying Dental Practice in 2026: The Complete Financial and Tax Due Diligence Guide

Buying a dental practice in the UK is one of the most significant financial decisions a dental professional can make. The purchase price may run into hundreds of thousands of pounds, with goodwill often representing a substantial part of the total consideration.

The financial, tax and contractual complexity of a dental practice acquisition is considerably greater than that of a standard business purchase. Completing detailed financial due diligence before exchanging contracts is essential. It can determine whether the acquisition becomes a sound investment or an expensive problem that only becomes apparent after completion.

Buying a dental practice in 2026 also requires buyers to consider recent tax and NHS contract changes. In England, the April 2026 NHS dental contract reforms changed how unscheduled care and complex care pathways affect practice income. Business Asset Disposal Relief increased to 18% for qualifying disposals from 6 April 2026, influencing negotiations between buyers and sellers.

Capital allowances also require careful attention. A Section 198 election may be needed to agree the value of qualifying fixtures included in the sale. Missing the relevant requirements can restrict the capital allowances available to the buyer.

This guide covers the financially important elements of buying a dental practice in the UK, including the initial financial review, goodwill valuation, tax structure, capital allowances, VAT, NHS contract arrangements and post completion accounting setup.

The detailed NHS contract and CQC sections relate primarily to dental practices in England. Different regulatory and commissioning arrangements apply in Wales, Scotland and Northern Ireland.

Financial Review: What to Request Before Making an Offer

Before making a formal offer, the buyer should obtain enough financial information to assess the practice’s profitability, income stability, cost base and future cash flow.

A basic sales summary showing headline turnover and profit is rarely enough to support an informed decision.

Three years of practice accounts

Request at least three years of complete practice accounts. This allows you and your advisers to assess:

• Whether revenue is increasing, stable or declining.
• Changes in wages, associate costs, laboratory fees and overheads.
• Unusual or one off costs.
• Equipment purchases and capital expenditure.
• Changes in NHS and private income.
• The level of profit generated before owner specific costs.
• Whether reported profits are supported by cash flow.

The accounts should be reconciled against tax returns, bank records and management information where available.

NHS payment schedules

For an NHS or mixed practice in England, request NHSBSA payment schedules for the same period.

These schedules can help verify:

• Core NHS contract income.
• UDA activity and performance.
• Enhanced service income.
• Quality Improvement Programme income.
• Complex care pathway credits.
• Previous clawbacks or adjustments.
• Superannuation deductions.
• Differences between recorded and received income.

NHS payment schedules should be reconciled against the income reported in the practice accounts.

Current NHS contract documents

Request the complete GDS or PDS contract, together with:

• Negotiated Annual Contract Value.
• Contracted UDA activity.
• Commissioned services.
• Contract variations.
• Performance and clawback history.
• Correspondence with the ICB or commissioner.
• Any breach, remedial or termination notices.
• Unscheduled care requirements.
• Complex care pathway records.

The 2026 reforms require affected practices in England with mandatory services contracts of at least 100 UDAs to deliver 8.2% of contract value through unscheduled care activity.

More information about the financial impact can be found in our guide to NHS dental contract reform April 2026.

Payroll and employment records

Request at least 12 months of payroll reports and all current employment contracts.

The review should cover:

• Gross salaries.
• Employer National Insurance.
• Workplace pension contributions.
• Holiday pay.
• Overtime and bonuses.
• Benefits in kind.
• National Minimum Wage compliance.
• Current vacancies and planned recruitment.
• Accrued holiday and other employment liabilities.

Employer NIC increased to 15%, and the secondary threshold reduced to £5,000, from April 2025. These rules continue to affect employment costs in 2026/27.

The National Living Wage for workers aged 21 and over increased to £12.71 from 1 April 2026. The buyer’s payroll model should therefore use current rates rather than historical figures from earlier accounts.

Associate agreements

Review every associate agreement and confirm:

• Whether the associate is employed or self employed.
• NHS and private income splits.
• Laboratory fee arrangements.
• Consumables deductions.
• Notice provisions.
• Restrictive covenants.
• Treatment of bad debts and refunds.
• Responsibility for remakes.
• NHS pension arrangements.
• What happens following a change of ownership.

The departure of a key associate following completion can materially reduce revenue and patient retention. Associate risk should therefore form part of both the valuation and the acquisition agreement.

Dental Practice Goodwill Valuation in 2026

Goodwill is often one of the largest components of a dental practice purchase price. It can include the value of the patient base, location, reputation, workforce, systems, NHS contract and future earning potential.

There is no universal goodwill multiple that can be applied reliably to every UK dental practice.

Adjusted profit and EBITDA

Adjusted profit or EBITDA is commonly used when valuing a dental practice. The calculation begins with reported profit and adjusts for items such as:

• Owner remuneration above or below a market rate.
• Personal expenses recorded through the practice.
• One off costs.
• Finance costs.
• Depreciation and amortisation.
• Exceptional professional fees.
• Non recurring revenue.
• Replacement principal or associate costs.

A valuation multiple may then be applied to the maintainable adjusted earnings. The appropriate multiple depends on the quality, stability and transferability of those earnings.

Revenue and turnover as a cross check

Turnover can be useful as a secondary valuation check, especially when comparing similar practices. It should not be used in isolation.

Two practices with identical turnover can have very different values if one has:

• Higher associate and laboratory costs.
• Lower patient retention.
• Greater dependence on the selling principal.
• A shorter lease.
• Poor NHS performance.
• Significant equipment replacement requirements.
• Lower adjusted profit.
• Greater compliance exposure.

Buyers should avoid relying on a fixed claim that every NHS mixed practice is worth 2 or 2.5 times annual turnover. A specialist valuation should consider adjusted earnings, revenue quality, operational risk and current market demand.

Factors affecting dental practice value

The valuation should consider:

• NHS, private and plan income mix.
• Historical revenue and profit trends.
• UDA performance.
• NHS clawback exposure.
• Private patient retention.
• Dependence on the selling principal.
• Associate stability.
• CQC compliance.
• Premises ownership or lease terms.
• Required capital expenditure.
• Competition and local demographics.
• Availability of acquisition finance.
• The buyer’s ability to maintain existing income.

Impact of the 2026 NHS contract reforms

For dental practices in England, buyers must consider how the reformed NHS contract affects future profitability.

Affected practices must allocate 8.2% of their contract value to unscheduled care. This may require changes to appointment capacity, staffing and clinical workflows.

Complex care pathways introduced during 2026 can generate additional credits for qualifying patients, but they also require appropriate enrolment, clinical delivery and administrative declarations.

The Quality Improvement Programme may provide an additional income stream where a practice has enrolled and continues to meet the programme conditions.

Buyers should confirm whether these income streams are recurring, achievable and supported by actual activity. Forecast income should not be included in the valuation simply because the seller expects to receive it.

For the official position, review NHS England’s guidance on the 2026/27 dental contract reforms.

Private income

A strong private patient base may support a higher valuation where income is recurring and transferable.

The buyer should distinguish between:

• Recurring plan income.
• Routine private dentistry.
• High value treatments.
• Cosmetic treatments.
• Income generated personally by the seller.
• Temporary treatment backlogs.
• Revenue dependent on a particular clinician.

Private turnover should be verified against patient records, practice management reports and bank receipts.

Tax Structure: Asset Purchase or Share Purchase

The tax structure of a dental practice acquisition has a material effect on both buyer and seller.

The transaction may be structured as an asset purchase or, where the practice operates through a limited company, a share purchase.

Asset purchase

In an asset purchase, the buyer acquires selected business assets. These may include:

• Goodwill.
• Equipment.
• Stock.
• Fixtures.
• Patient records, subject to legal and data protection requirements.
• Business contracts.
• The right to occupy the premises.
• Other operating assets.

An asset purchase may allow the buyer to avoid inheriting some historic company liabilities. However, liabilities can still transfer through contracts, employment law, tax rules or the purchase agreement.

The buyer may also be able to claim capital allowances on qualifying equipment and fixtures, subject to the allocation of the purchase price and the relevant capital allowances requirements.

Share purchase

In a share purchase, the buyer acquires the company that owns and operates the practice.

The company continues to own its assets, retain its contracts and carry its liabilities. This can make operational continuity easier, but the buyer also acquires the company’s tax, legal, employment and compliance history.

Detailed legal, financial and tax due diligence is particularly important in a share purchase. The buyer should seek suitable warranties, disclosures and indemnities.

Seller’s tax position

A qualifying share sale can produce a capital gain for the seller. From 6 April 2026, the Business Asset Disposal Relief rate is 18% on qualifying gains, subject to the £1 million lifetime limit and all eligibility conditions.

Where BADR does not apply, standard Capital Gains Tax rates may apply.

A company asset sale can create tax at company level, followed by additional tax when the proceeds are extracted. This is one reason sellers may prefer a share sale.

Negotiating the structure

The buyer and seller may prefer different structures. The financial effect should be modelled before heads of terms become binding.

The review should consider:

• Buyer capital allowances.
• Seller Capital Gains Tax.
• Corporation Tax.
• Extraction tax.
• Stamp taxes.
• Historic liabilities.
• Professional costs.
• Funding requirements.
• Commercial risk.

Obtain specialist business tax advice before agreeing the transaction structure.

Capital Allowances and the Section 198 Election

Capital allowances are one of the most frequently missed areas of dental practice acquisition due diligence.

Dental practices can contain significant qualifying plant and machinery, including equipment and fixtures incorporated into the premises.

Loose equipment and fixed fixtures

Loose equipment may include dental chairs that are not fixed to the property, computers, sterilisation equipment and movable machinery. These assets are normally considered separately from fixtures forming part of the property.

Fixed fixtures may include:

• Integrated plumbing.
• Electrical installations.
• Ventilation systems.
• Fixed cabinetry.
• Certain dental chair bases.
• Heating and cooling systems.
• Other integral features.

The treatment depends on the nature of the asset and how it is attached to the property.

Section 198 election

Where qualifying fixtures are transferred with an interest in property, the buyer and seller may need a Section 198 election to fix the value transferred for capital allowances purposes.

The election normally needs to be made within two years of the property transfer. The seller’s previous pooling position and the fixed value requirements must also be reviewed.

The election should be addressed during the acquisition, rather than left until after completion.

Value of the capital allowances

The available relief depends on:

• The original qualifying expenditure.
• Whether the seller pooled the expenditure.
• Previous capital allowance claims.
• The agreed disposal value.
• Asset classification.
• The buyer’s tax position.
• Availability of the Annual Investment Allowance or other reliefs.

A fixtures analysis should be completed before the allocation in the purchase agreement is finalised.

Our specialist dental accountants can review the accounts, fixtures schedule and purchase price allocation as part of dental acquisition due diligence.

Writing Down Allowance from April 2026

The main pool Writing Down Allowance reduced from 18% to 14% from:

• 1 April 2026 for Corporation Tax.
• 6 April 2026 for Income Tax.

A hybrid rate may apply where an accounting period crosses the change date.

The reduced annual rate does not eliminate the value of capital allowances. It changes the timing of the tax relief and should be incorporated into acquisition cash flow forecasts.

VAT in a Dental Practice Acquisition

The VAT treatment depends on the structure of the transaction, the assets transferred and the income generated by the practice.

Transfer of a Going Concern

An asset purchase may qualify as a Transfer of a Going Concern where the buyer acquires a functioning business and continues the same kind of activity.

Where all conditions are met, the transfer is outside the scope of VAT. This can prevent the buyer from having to fund VAT on the purchase price while waiting to recover it.

TOGC treatment is not automatic. The contractual position and the buyer’s intended activities must be reviewed before completion.

When TOGC may not apply

TOGC treatment may not be available where:

• Only selected assets are purchased.
• The business has ceased trading.
• The buyer does not continue the same type of business.
• The required VAT conditions are not met.
• The transaction is structured as a simple equipment purchase.

VAT may then apply to standard rated elements of the transaction.

Cosmetic dental income

Most qualifying dental treatment provided for the protection, maintenance or restoration of health is exempt from VAT.

Purely cosmetic procedures may be standard rated where their primary purpose is not therapeutic. The treatment should be assessed according to its purpose and the patient’s clinical circumstances rather than its name alone.

If the practice provides cosmetic dental or facial aesthetic services, ask a VAT specialist to review:

• The seller’s VAT registration.
• Historic VAT treatment.
• Taxable turnover.
• Partial exemption calculations.
• VAT records.
• TOGC requirements.
• The buyer’s registration position.

NHS Dental Contract Transfer in England

An NHS GDS or PDS contract does not transfer in the same way as an ordinary commercial contract.

The appropriate process depends on the contract type, the seller’s legal structure and the buyer’s proposed ownership structure. It may involve partnership changes, commissioner approval, contract variation or a new contractual arrangement.

The buyer should involve a specialist dental solicitor and accountant before agreeing the completion mechanism.

Commissioner approval

The relevant ICB or NHS contracting authority may require:

• Application documents.
• Performer and provider information.
• CQC documentation.
• Financial information.
• Ownership details.
• Contract variation documents.
• Confirmation of proposed completion arrangements.

Completion should be coordinated carefully with NHS and CQC processes to avoid disruption to patient services or payment.

Payment continuity

The purchase agreement should explain how NHS payments around completion will be treated.

It should cover:

• Pre completion income received after completion.
• Post completion income received by the seller.
• UDA under delivery.
• Clawbacks.
• Contract adjustments.
• Superannuation deductions.
• Reconciliation procedures.

UDA performance and clawback

The buyer should assess UDA performance at the intended completion date.

If the practice is behind its target, the purchase agreement should specify who bears responsibility for any clawback relating to the seller’s ownership period.

This may be addressed through:

• A purchase price adjustment.
• A retention.
• A warranty.
• A specific indemnity.
• A completion accounts mechanism.

CQC and Regulatory Due Diligence in England

The buyer should review the practice’s CQC registration and compliance history.

The review should include:

• Registered provider details.
• Registered manager details.
• Inspection reports.
• Warning or requirement notices.
• Outstanding action plans.
• Complaints.
• Safeguarding records.
• Radiation compliance.
• Infection prevention procedures.
• Staff training records.

A rating below Good does not automatically prevent the practice from accepting NHS patients. However, unresolved compliance concerns may require remedial expenditure, management time or operational changes.

Any regulatory concern should be reflected in the valuation, warranties and acquisition plan.

Post Completion Accounting Setup

Correct accounting setup from the first day of ownership makes it easier to monitor profitability, NHS performance, cash flow and tax.

Separate income codes

The chart of accounts should include separate codes for:

• NHS core contract income.
• Unscheduled care income.
• Complex care pathway credits.
• Quality Improvement Programme income.
• Enhanced services.
• Private treatment categories.
• Dental plan income.
• Cosmetic treatment income.
• Other taxable income.

Combining all revenue in one account makes it difficult to compare actual performance with the acquisition forecast.

Associate payment schedules

Associate calculations should show:

• Gross NHS and private income.
• The associate’s agreed share.
• Laboratory deductions.
• Consumables deductions.
• NHS pension deductions where applicable.
• Adjustments and remakes.
• Net payment.

The accounting records should capture the gross income and each deduction, rather than recording only the net payment.

NHS reconciliations

The first NHSBSA payment schedule under the new ownership should be reconciled against:

• Expected contract income.
• UDA submissions.
• Unscheduled care activity.
• Complex care credits.
• Superannuation.
• Prior period adjustments.
• Any seller related income.

Monthly reconciliation helps identify errors while they are still straightforward to investigate.

Payroll under the new employer

Where TUPE applies, employees may transfer to the buyer on their existing terms and conditions. The exact position should be reviewed by an employment solicitor.

The buyer may need to:

• Register a PAYE scheme.
• Complete payroll onboarding.
• Assess workplace pension duties.
• Apply employer NIC at 15%.
• Apply the current minimum wage.
• Calculate holiday entitlement correctly.
• Report payments through RTI.
• Provide compliant payslips.

For qualifying irregular hours or part year workers, rolled up holiday pay may be calculated at 12.07% and must be separately identified on the payslip.

Our payroll for healthcare and bookkeeping for healthcare services can help configure the chart of accounts, payroll and NHS reconciliation process before the first month end.

Summary: Complete Due Diligence Before You Sign

Buying a dental practice in 2026 requires more than reviewing headline turnover and accepting the seller’s asking price.

The buyer should verify:

• Maintainable profit and cash flow.
• NHS and private income.
• UDA performance and clawback exposure.
• The effect of the 2026 NHS reforms in England.
• Goodwill valuation.
• Associate and employee retention.
• Asset purchase and share purchase tax consequences.
• Capital allowances and the Section 198 election.
• VAT and TOGC treatment.
• NHS contract arrangements.
• CQC compliance.
• Post completion accounting and payroll.

The most expensive acquisition mistakes usually begin before completion. Missing a capital allowances requirement, overvaluing non recurring income, inheriting an unidentified liability or failing to address NHS clawback can cost considerably more than specialist due diligence.

If you are considering incorporating a dental practice, review the ownership structure before agreeing how the acquisition will be completed.
