Frequently Asked Questions

Is London weighting taxable?

Yes, NHS High Cost Area Supplements are treated as taxable income. They are also pensionable, meaning you pay pension contributions on the total including weighting.

Do all NHS staff in London get weighting?

Most Agenda for Change staff receive it, but eligibility depends on your NHS trust and exact workplace location. Some administrative or back-office roles in London may not qualify if based outside the designated zone.

Does London weighting affect my pension?

Yes. Because it is pensionable, your NHS pension contributions are calculated on your basic salary plus weighting. This means you pay slightly more in pension contributions but also build up slightly more pensionable service.

Inner London covers central zones and attracts the highest supplement (up to £6,000). Outer London covers suburban zones and surrounding areas with a lower supplement (up to £3,661). Fringe areas are just outside the M25 with a flat £1,192 supplement.
