How to Use the HCAS Calculator
Our NHS HCAS Calculator helps you estimate the High Cost Area Supplement (HCAS) you may receive based on your NHS pay band and work location. Simply select your NHS pay band, choose your London Weighting zone, and the calculator will instantly display your estimated annual, monthly, and weekly HCAS payments.
The calculator uses the latest 2026/27 NHS HCAS rates, including minimum and maximum payment caps for Inner London, Outer London, and Fringe Areas.
What Is NHS London Weighting (HCAS)?
London Weighting is an additional payment for NHS staff who work in London and the surrounding areas. It is also known as "London Allowance" or High Cost Areas Supplement (HCAS). London Weighting was originally introduced to help public sector employees — including NHS staff, teachers, and police officers — cope with the higher cost of living in London.
In the NHS, London Weighting is paid by the NHS employer as part of the High Cost Area Supplement scheme, which is approved by the Government. The rates are set nationally according to the Agenda for Change (AfC) pay system.
NHS HCAS Rates 2026/27
The NHS HCAS rate depends on your location. There are three HCAS zones, each with its own rate and payment limits.
Inner London
Outer London
Fringe Area
Inner London HCAS Rate
NHS employees who work in Inner London receive the highest HCAS. For 2026/27, eligible jobholders receive 20% of their basic salary, subject to a minimum of £5,794 and a maximum of £8,746.
Inner London covers central London boroughs and NHS Trusts where the cost of housing, transport, and daily living expenses is significantly higher than the UK average. This supplement can increase annual earnings by several thousand pounds, depending on your NHS pay band and location.
Boroughs typically classified as Inner London HCAS:
Outer London HCAS Rate
NHS employees working in Outer London may qualify for a High Cost Area Supplement worth 15% of their basic salary. The supplement helps offset the higher housing, transport, and living costs associated with working in Outer London.
The extra payment is added to your basic NHS pay before tax deductions. The exact amount depends on your NHS pay band and annual salary, and will not fall below the minimum or exceed the maximum limit.
Boroughs typically included in the Outer London HCAS zone:
Fringe Area HCAS Rate
NHS staff working in the Fringe Area receive 5% of their basic salary as a supplement. Although living costs are slightly lower than in Inner or Outer London, they remain higher than the UK average. Like other HCAS zones, the Fringe supplement is added to employees' basic salary before tax and National Insurance deductions.

Does HCAS Affect Take-Home Pay?
Yes, NHS HCAS increases your overall take-home pay because it is added to your basic salary before payroll deductions are applied. Although some amount is deducted in tax and pension contributions, most NHS employees still benefit from a higher net salary compared to staff working outside HCAS areas.
Income Tax (2026/27)
National Insurance (2026/27)
NI contributions are calculated on your total NHS earnings including HCAS. Since HCAS increases your gross pay, it can lead to higher NI contributions.
NHS Pension
NHS HCAS generally forms part of your pensionable earnings, meaning it can affect both your pension contributions and pension growth.
London Weighting vs London Living Wage
These two terms are often used interchangeably, but they are completely different schemes.
London Weighting (HCAS) is an additional payment provided by the NHS employer, calculated as a percentage of an employee's basic salary. It varies by zone — Inner London, Outer London, or Fringe Area.
London Living Wage is an independently calculated hourly pay rate that reflects the actual cost of living in London. It is the same rate across all of London.
Key Differences
| Feature | London Weighting (HCAS) | London Living Wage |
|---|---|---|
| Purpose | Additional salary supplement | Minimum recommended hourly pay |
| Who receives it? | Eligible employees in London areas | Workers at Living Wage employers |
| NHS Staff Eligible? | Yes, if working in HCAS zones | Not specifically an NHS benefit |
| Calculation Method | Percentage of salary | Fixed hourly rate |
| Taxable? | Yes | Forms part of normal taxable earnings |
| Varies by Location? | Yes (Inner, Outer, Fringe) | One rate for all of London |
Why Is HCAS Important for Employers?
The NHS HCAS benefits not only employees but also NHS organisations. It helps NHS Trusts recruit and retain skilled healthcare professionals in London and surrounding regions.
- Helps NHS Trusts compete with private healthcare employers
- Minimises recruitment challenges in high-cost living areas
- Encourages long-term employee retention and reduces turnover
- Lowers vacancy rates across NHS services
