When a Part Time PA Fits a London Business

A part time PA fits when the support workload is defined, predictable and fills two to four days, so paying for a full-time seat would buy idle hours. Cost is the clearest driver, because part time pay is pro-rata, and a role that genuinely needs three days should not carry a five-day salary. The saving is real only when the workload truly matches the hours.

Part time also suits a growing business testing the need for support before committing to a full seat. Flexible cover is easier to source than it has been, with UK temp and flexible billings at a three-year high in 2026 (KPMG/REC, Aug 2026), and executive support roles increasingly work across hybrid and flexible patterns. Scoping the level first matters, because how a personal assistant differs from an executive assistant affects how much continuity a part time pattern can carry.

How many days does a part time PA work?

A part time PA usually works two to four days a week, or set hours across shorter days, matched to when the support workload falls. Diary and inbox cover suit shorter daily hours, while project support suits full days. Listings show three days a week as the most common pattern in London, at £21,000 to £24,000 actual pay (Totaljobs, 2026).

What a Part Time PA Costs in London

A part time PA in London costs pro-rata to a full-time base of £37,500 to £59,750 (Robert Half London, 2026), so a three-day role runs roughly 60% of that figure. Real listings put a three-day London PA at £21,000 to £24,000 on a £35,000 to £40,000 full-time-equivalent salary (Totaljobs, 2026), while Morgan McKinley places the full-time London PA average at £45,000 to £55,000. The saving holds only when the hours genuinely cover the workload.

Temporary part time cover is priced by the hour. A temporary London PA or team assistant runs around £22 to £26 an hour in 2026 (Tiger Recruitment listings, 2026), which suits absence, projects and short-term gaps. Weighing the true cost of that cover against a permanent part time seat is the decision, and the true cost of executive support is what it should turn on.

How much does a part time PA cost in London?

A part time PA in London costs pro-rata to a full-time base of £37,500 to £59,750, so a three-day role runs roughly £21,000 to £24,000 in actual pay (Robert Half and Totaljobs, 2026).

How Morgan Spencer Hires Part Time PAs in London

Step 1. Measure the true workload. List the tasks the role must own and total the hours across a typical week, so the days match the demand rather than the budget.

Step 2. Set the pro-rata package. Benchmark the full-time equivalent to the live London band of £37,500 to £59,750, then price the part time salary to the days worked.

Step 3. Scope the level. Define whether the role is a PA or a more senior executive assistant, because the level affects how much continuity a part time pattern carries.

Step 4. Match from a specialist pool. Draw part time and flexible PAs from a screened pool rather than a cold advert, because specialist agencies fill PA roles in days where job boards take six weeks.
