A dental associate agreement is the contract that sets out how a self-employed associate dentist works within a practice, including how they are paid, what they are responsible for, and what happens if either side wants to end the arrangement. Since HMRC withdrew, from 6 April 2023, the automatic assumption that associates engaged on BDA or Dental Practice Business (DPB) approved contract terms were self-employed for tax purposes, the wording of this agreement matters more than it used to, not less.

This post sets out the terms an associate, or a practice owner engaging one, should check carefully before signing. It sits alongside our sub-hub on dental practice partnership agreements, for associates weighing up a future partnership offer, and our dedicated post on restrictive covenant enforceability, which goes deeper on the non-compete and non-solicitation terms most associate agreements contain.

Self-Employed Status: Why the Contract Wording Now Carries Real Risk

Until April 2023, HMRC guidance provided a form of safe harbour: associate dentists engaged under the BDA’s or DPB’s approved model contract terms were generally accepted as self-employed for tax purposes provided the contract was followed in practice, without HMRC scrutinising the individual working arrangement further. HMRC withdrew that specific guidance with effect from 6 April 2023. Since then, an associate’s employment status for tax purposes is assessed case by case under HMRC’s ordinary employment status principles, using the same tests (control, substitution, mutuality of obligation, financial risk) that apply to any other engagement, not by reference to which model clause set the contract happens to be based on.

This does not mean associates can no longer be genuinely self-employed. Most still are, and self-employed status remains the norm across the sector. What it means is that the contract’s terms have to actually reflect self-employed working in practice, not just recite the right words. A contract that says “the associate is self-employed” while the practice dictates the associate’s hours, supplies all equipment and materials without charge, and controls how the associate treats every patient looks a lot more like disguised employment to HMRC than the label suggests. If HMRC successfully reclassifies an associate as employed, the practice can face a retrospective PAYE and employer’s National Insurance liability, which is why many current associate agreements now include an indemnity requiring the associate to cover the practice’s losses if a reclassification arises from the associate’s own conduct or misrepresentation. If you are asked to sign an indemnity of this kind, understand exactly what you are underwriting before you agree to it, and take advice if the wording is broad enough to catch outcomes outside your control.

Key Terms to Check Before Signing

1. Payment Terms and UDA/UDA Value (NHS Associates)

For NHS-facing associates, the agreement should set out clearly how the associate is paid against Units of Dental Activity (UDAs), the UDA value applied, and what happens if the practice under-delivers or over-delivers against its overall NHS contract target during the year. Private fee income should be dealt with separately, typically as a percentage split of fees generated, with clarity on how lab fees and materials are deducted before the split is calculated.

2. Hours, Sessions and Autonomy

Genuine self-employed status is supported by the associate retaining meaningful control over how the work is carried out, for example the ability to determine their own clinical approach, take on locum cover, and decline specific patients or treatments within professional guidelines. An agreement that fixes every aspect of the associate’s working day in the same way an employment contract would undermines the self-employed position it claims to establish.

3. Equipment, Materials and Overheads

Check what the associate is charged for (surgery use, nursing support, materials, laboratory fees) and how those charges are calculated. Genuinely self-employed arrangements typically involve the associate bearing some element of financial risk and cost, rather than working entirely cost-free within the practice’s infrastructure.

4. Notice Periods and Termination

Standard notice periods in dental associate agreements are commonly around three months, though this varies and should be checked against the specific agreement rather than assumed. Check what constitutes grounds for immediate termination (serious misconduct, GDC fitness to practise issues, loss of GDC registration) versus termination on notice, and whether the notice period is symmetrical between associate and practice.

5. Indemnity Insurance

The agreement should require the associate to maintain adequate professional indemnity insurance throughout the engagement and to provide evidence of cover on request. Confirm whether the practice’s own indemnity arrangements extend to associates or whether the associate must hold entirely separate cover.

6. Restrictive Covenants

Almost every associate agreement includes non-compete and non-solicitation clauses restricting the associate from working within a set radius of the practice, or treating the practice’s patients, for a period after leaving. These clauses are only enforceable where they go no further than reasonably necessary to protect a legitimate business interest, and poorly drafted covenants are struck down regularly. This is significant enough that we cover it in full in a dedicated post: restrictive covenants in dental associate agreements, are they enforceable?

7. GDC Registration and Compliance

The agreement should make continued GDC registration, and compliance with GDC standards, a condition of the engagement, with a clear right for the practice to suspend or terminate if registration lapses or is subject to interim conditions. The 2026 GDC Annual Retention Fee is £698 for dentists, and lapsed payment (not just misconduct) is a genuine cause of registration lapsing if missed.

8. Restrictive Terms on Patient Records and Data

Check who owns patient records and clinical data generated during the engagement (normally the practice, given its status as data controller under UK GDPR) and what the associate is entitled to access or take copies of on leaving, particularly relevant if the associate later sets up independently.

What This Means for You

Whether you are an associate about to sign your first agreement, or a practice owner updating your standard associate contract in light of the change in HMRC’s approach since 2023, the specific wording matters more than it once did. A contract that worked perfectly well five years ago may now carry more tax risk than either party realises, and a covenant that looked standard may not survive a challenge if it is drafted too broadly.
