The earnings figure most often quoted for NHS dentists is the gross. It is the number that appears in press coverage, in contract negotiations and, occasionally, in comments sections. In 2024/25 the average gross earnings for a self-employed primary-care NHS dentist in England were £167,500. That figure is real, but it is also almost entirely misleading as a guide to what dentists actually keep.
After subtracting the costs of running the practice, average net income before tax was £83,000. Average expenses were £84,500. The cost of generating that gross income absorbed, in other words, just over half of every pound earned. Understanding why, how this ratio has moved since 2017/18, and what it means for the tax and structure decisions facing associates and practice owners is what this analysis sets out to do.
All figures in this article are drawn from the NHS England Digital Dental Earnings and Expenses Estimates bulletin for 2024/25[1], released on 30 July 2026 and published under the Open Government Licence v3.0. They are England figures covering all dental types and all contract types. You can explore the underlying data on our NHS dentist earnings index.

The 2024/25 headline figures
The table below sets out the core 2024/25 breakdown for England. These figures cover self-employed primary-care NHS dentists; they do not include private-only practitioners or salaried NHS employees. Net income is income before tax and National Insurance.
| Measure | 2024/25 (England) | 2023/24 (England) | Year-on-year change |
|---|---|---|---|
| Average gross earnings | £167,500 | £158,100 | +£9,400 |
| Average expenses | £84,500 | £79,900 | +£4,600 |
| Average net income (before tax) | £83,000 | £78,200 | +£4,800 |
| Median net income (before tax) | £69,200 | £64,700 | +£4,500 |
| Expense ratio (expenses as % of gross) | 50.4% | 50.5% | −0.1 pp |
The most important detail in that table is that the gain came from the top line rather than from cost control. Gross earnings rose £9,400 and expenses rose £4,600, so net income rose £4,800 with the expense ratio essentially unchanged at just over 50 percent. That is a different picture from 2023/24, when the rise in net income came from expenses falling. For a practice owner the read is that the overhead block is sticky: it moves broadly in step with turnover, so a durable rise in take-home pay has to come from turnover or from a structural change to the cost base, not from incidental savings.
The second important detail is the gap between average and median. Average net income was £83,000. Median net income was £69,200, a £13,800 difference. The distribution is skewed by a minority of high earners, so the median is a more realistic guide to what a typical NHS dentist actually takes home before tax. If you are benchmarking your own position, the median is the more relevant reference.
What the expenses actually are
Expenses in the bulletin are not the associate's own professional costs. They are the costs of running the practice as a business: the wages of nurses, receptionists and dental hygienists; the dental laboratory fees for crowns, bridges and dentures; clinical consumables and materials; premises costs (rent, business rates, utilities); equipment service contracts; professional indemnity cover as a practice; and software and administrative overheads.
For a practice owner, these costs sit between the gross income and the net. They are real business expenditure, largely allowable against income tax under the trading income rules. But they are also uncontrollable in part: the laboratory bill is driven by the treatment mix, nurse salaries by the number of surgeries operating, and premises costs by the lease agreement in force. The room to reduce expenses significantly is narrower than it can look from the outside.
An associate's position is different. An associate working in someone else's practice does not bear the practice overhead. Their costs are the smaller set of personal professional expenses: indemnity, CPD and registration fees, professional subscriptions, any equipment they supply themselves and, where allowable, the cost of travel between practices. The result is that an associate typically keeps a much higher proportion of their NHS associate fee than a practice owner keeps of the contract value. The detailed rules on what associates can claim are set out on our associate tax guide.
Regional variation: London's expense squeeze
The national average conceals significant regional spread. The table below shows the full English regional picture for 2024/25.
| Region | Average gross | Average expenses | Average net | Expense ratio |
|---|---|---|---|---|
| East of England | £190,500 | £100,000 | £90,500 | 52.5% |
| London | £168,000 | £91,100 | £76,800 | 54.2% |
| Midlands | £170,300 | £89,100 | £81,200 | 52.3% |
| North East and Yorkshire | £167,100 | £79,200 | £87,900 | 47.4% |
| North West | £162,700 | £82,000 | £80,700 | 50.4% |
| South East | £155,500 | £74,700 | £80,700 | 48.0% |
| South West | £160,300 | £71,600 | £88,700 | 44.7% |
| England (all) | £167,500 | £84,500 | £83,000 | 50.4% |
London is the clearest outlier. Gross earnings of £168,000 sit almost exactly on the national average, but expenses of £91,100 are the second-highest of any region, producing a net income of £76,800, the lowest of any English region. The expense ratio of 54.2 percent against 47.4 percent for North East and Yorkshire illustrates how sharply London premises costs, staffing costs and laboratory rates can erode the same headline gross. A London dentist nets £11,100 a year less than a counterpart in North East and Yorkshire on a very similar gross, simply because of the overhead structure. At the other end, the South West combines the lowest expense ratio in England at 44.7 percent with the second-highest net income at £88,700.
This gap has direct implications for practice valuation, for whether a London practice justifies incorporation, and for the return on any capital invested in a London practice acquisition. Our guide on how much of a dental practice price is goodwill discusses how the profitability position feeds into what a buyer should pay.
The trend: gross, expenses and net from 2017/18
The data below is drawn from Table 1.1 of the published NHS England Digital UK time series workbook[1] and covers England from 2017/18 to 2024/25. The workbook runs back to 2008/09, but it marks England as not applicable for every year before 2017/18, so 2017/18 is the earliest year for which an England figure exists on this basis. All figures are nominal (not inflation-adjusted).
| Year | Avg gross earnings | Avg expenses | Avg net income | Expense ratio |
|---|---|---|---|---|
| 2017/18 | £146,700 | £78,100 | £68,500 | 53.2% |
| 2018/19 | £147,100 | £78,500 | £68,600 | 53.4% |
| 2019/20 | £144,700 | £76,100 | £68,600 | 52.6% |
| 2020/21 [*] | £141,400 | £68,900 | £72,500 | 48.7% |
| 2021/22 | £156,100 | £78,200 | £77,900 | 50.1% |
| 2022/23 | £155,200 | £79,300 | £75,800 | 51.1% |
| 2023/24 | £158,100 | £79,900 | £78,200 | 50.5% |
| 2024/25 | £167,500 | £84,500 | £83,000 | 50.4% |
[*] 2020/21 figures are distorted by NHS Covid support payments to dental contractors. The apparent increase in net income relative to prior years reflects the support mechanism rather than underlying earnings growth, and the expense ratio is correspondingly lower because activity (and therefore variable costs) was reduced while support income was maintained.
Several findings stand out from the series.
Nominal gains are real but modest. Average net income rose from £68,500 in 2017/18 to £83,000 in 2024/25, a nominal increase of 21.2 percent over seven years. Against cumulative consumer price inflation over the same period, which included the 2022 and 2023 spike, that nominal gain largely disappears. In real terms NHS dentist earnings have broadly tracked rather than meaningfully outpaced inflation.
Earnings were flat before Covid, not rising. Average net income sat at £68,500, £68,600 and £68,600 in 2017/18, 2018/19 and 2019/20: three consecutive years of no movement at all in nominal terms, which is a real-terms cut of several percent a year. Gross earnings actually fell over those three years, from £146,700 to £144,700, while the expense ratio held above 52 percent. Staff wages, laboratory costs, premises and regulatory compliance costs all grew while NHS contract values were constrained.
The recovery has come in two different ways. The expense ratio dropped to 48.7 percent in 2020/21, but that is an artefact of Covid support income arriving while activity, and therefore variable cost, was suppressed. Since then the ratio has settled in a narrow band between 50.1 and 51.1 percent, and net income has risen from £72,500 to £83,000. In 2023/24 the gain came from expenses falling; in 2024/25 it came from gross earnings rising £9,400 while the ratio held. The second is the more durable of the two.

What this means for associates
An associate working under a self-employed agreement receives a portion of the contract income rather than the full contract value. The practice owner bears the practice overhead; the associate bears only their own direct professional costs. The result is that an associate's expense ratio against their own gross receipts is considerably lower than the 50 percent seen at practice level.
For an associate whose gross income runs at, say, £60,000 to £80,000 per year, the relevant expenses are typically limited to: indemnity, CPD and registration fees, professional subscriptions, clinical equipment they personally supply and, where the arrangement qualifies, travel between practice sites. These costs can often be brought well below 10 percent of gross income, leaving a materially higher net income as a proportion of what comes in. The practical guide to what associates can and cannot claim is on our associate and locum tax page.
The associate's exposure, though, is to the decisions the practice owner makes. If the practice overhead rises, the owner's net income falls. The associate is insulated from that in the short term but is affected if the owner's response is to renegotiate the associate fee or take the practice private. Understanding the owner's financial position is therefore useful context even for an associate with no ownership ambitions.
What this means for practice owners: tax and structure
For a practice owner, the gross-to-net gap has direct consequences for every tax and structure decision.
Income tax is on net, not gross. A practice owner with average 2024/25 figures faces income tax and Class 4 National Insurance on £83,000, not on £167,500. The effective marginal rates on £83,000 (part in the basic-rate band at 20 percent plus 6 percent Class 4, part in the higher-rate band at 40 percent plus 2 percent) are very different from those on the headline gross, and the self-employed National Insurance position changes with the profit level. Benchmarking tax burden or structure decisions against gross income rather than net income consistently overstates the problem and produces the wrong answer.
The incorporation decision turns on net profit, not gross. Whether a dental limited company improves the overall tax position depends on the net profit that enters the company, not the gross earnings flowing through the practice. A practice generating £167,500 gross with £84,500 of expenses has net profit of £83,000 to work with. That is a meaningfully different starting point for the corporation tax and dividend analysis than a practice generating the same gross with a lower expense base and a higher net. The 2026/27 dividend rate rise makes the extraction case narrower; our guide to whether incorporation is still worthwhile in 2026/27 models the actual breakevens. For a full comparison of profit extraction routes, see our practice profit extraction guide.
Expense deductibility shapes the tax cost significantly. Because practice expenses are deductible in computing the trading profit on which income tax and Class 4 National Insurance are charged, the £84,500 of average expenses is not simply money spent: it is spending that reduces the tax bill. A practice owner replacing an allowable expense with a non-deductible one (for example, a personal cost that does not meet the wholly and exclusively test) not only spends the money but loses the deduction, so the after-tax cost is higher than the face value. Getting the expense classification right is a material financial matter, not an administrative one.
The overhead base affects what a practice is worth. Practice valuations are fundamentally driven by maintainable profit. A practice that has held its expense ratio at 50 percent while a comparable practice has drifted to 55 percent is, all else equal, worth more per pound of gross income because there is more net income to buy. The trend in expense ratios is therefore directly relevant to practice buyers and sellers. Our guide on dental practice exit planning discusses how to prepare the accounts position ahead of a sale.
Summary
The data from NHS England Digital presents a consistent picture across the eight reported England years. Gross earnings for self-employed primary-care NHS dentists have risen in nominal terms, but expenses have risen alongside them, absorbing roughly half of every pound earned in every year except the Covid-distorted 2020/21. In 2024/25 the expense ratio was 50.4 percent, effectively unchanged on 2023/24, and the £4,800 rise in net income came from gross earnings rather than from cost savings.
The median net income of £69,200 is the most grounded benchmark for a typical dentist's pre-tax take-home from NHS work. The average of £83,000 is pulled upward by a minority of higher earners. London practices are the clearest regional outlier, with the highest expenses and the lowest net income of any English region despite above-average gross earnings.
For associates and principals making decisions about tax structure, incorporation, practice acquisition or eventual exit, the working figure is always net income, not gross. The gross is real, but it does not arrive at the bank account.
