Administrator salary in South East

£28,000 – £32,125 (median £30,000 · 25th–75th pct)

How this figure was built. Based on 28 live advertised salaries for this role and region.

Methodology: medians reconcile live advertised UK salaries for this role and region; 25th–75th percentiles are shown only where at least 5 live salaried listings back them. They are measured or omitted, never interpolated. Rows marked indicative are anchored to our curated 2026 baseline ranges until enough live data accrues. Listings advertising an implausible annual figure (a mislabelled hourly or daily rate) are excluded rather than converted, because converting one means guessing the hours behind it.

Market view. Junior and data-entry roles sit at the bottom of the band, experienced and specialist administrators (finance, HR, legal, contracts) in the middle and office managers at the top (£32,000–£45,000). The public sector and NHS pay to published bands; professional services pay most.
