How NHS Dentistry Works
NHS dentistry in England runs on a system of Units of Dental Activity, or UDAs. If you have trained abroad, this way of paying for treatment is often the biggest adjustment. This guide explains the contract, how your pay is built, and how NHS, private, and mixed practice actually compare.
The UDA system
A UDA is the unit the NHS uses to measure the treatment a practice delivers. Each NHS practice holds a contract with a yearly target, for example 10,000 UDAs, and is paid a set budget to deliver them. Every completed course of treatment earns a fixed number of UDAs based on the treatment band, regardless of how long the work takes.
This is the part that surprises many dentists new to the UK. A single filling and five fillings both sit in the same band and earn the same UDAs. Understanding that helps you read a contract and plan your clinical day.
Band 1
1 UDAExamination, diagnosis, advice, scale and polish if clinically needed, and preventive care such as X-rays.
Band 2
3 UDAsEverything in Band 1 plus further treatment such as fillings, root canal work, and extractions.
Band 3
12 UDAsEverything in Bands 1 and 2 plus laboratory work such as crowns, dentures, and bridges.
Patients pay a fixed charge for their course of treatment, and some patients are exempt. Note that patient charges fall into four categories, not three: the three treatment bands plus a separate urgent-care charge. As of April 2025 the charges in England are Band 1 £27.90, Band 2 £76.60, Band 3 £332.10, and urgent or emergency treatment £27.90, the same as Band 1. The charges change every April, so check the current figures on the NHS website.
How your pay is structured
Most dentists start as associates rather than owning a practice. As an NHS associate you are usually self employed and paid on a UDA rate. Your income comes from three things working together: the rate the practice pays you per UDA, the number of UDAs in your agreed commitment, and the days you work each week.
Out of what you earn, you normally pay a laboratory fee share, your own tax and National Insurance, your indemnity, and your GDC retention fee. In a mixed practice you also earn a percentage of any private treatment and hygienist referrals you generate, which can lift your total income above the NHS portion alone.
Because UDA rates, targets, and private percentages differ from practice to practice, there is no single national salary for an associate. It is worth comparing two or three offers on the full package, not just the headline rate, before you commit. The British Dental Association publishes guidance on associate agreements that is worth reading first.
NHS, private, and mixed practice
NHS practice
You work to a UDA target agreed with the practice. Income is steadier and patient flow is high, but the pace can be demanding because the same UDA value applies whether a course of treatment is quick or complex.
Private practice
You charge fees set by the practice rather than working to UDAs. There is usually more clinical time per patient and broader treatment options, but you rely on the practice's private patient base, which takes time to build.
Mixed practice
You hold an NHS UDA commitment alongside private work in the same building. This is the most common arrangement in England and lets you balance steady NHS income with higher-value private treatment.
You need the Performers List for NHS work
GDC registration lets you practise dentistry in the UK, but it does not by itself let you treat NHS patients in England. For that you must also be on the Dental Performers List, which is managed by Primary Care Support England, known as PCSE. You apply online through PCSE using your GDC number, and you cannot claim NHS work until your name is on the list.
Many dentists who trained overseas join the NHS through a route called Performers List Validation by Experience, or PLVE, which pairs a period of supervised NHS practice with a mentor before full entry to the list. Your prospective practice will usually guide you through this. Start at the PCSE dental performers page to see the current requirements.
A system under reform
The UDA contract has been widely criticised for underpaying complex care, and the Government has been consulting on reforms, including changes aimed at higher needs patients. The detail is still moving, so treat any contract you are offered as current practice rather than settled policy, and follow updates on NHS England and the British Dental Association.
