To hire a virtual administrative assistant in the UK, write down the tasks you want off your desk, set your hours, then pick one of three routes: a freelance platform, a UK agency, or a dedicated offshore provider. UK agencies charge £25 to £40 an hour. Screen for judgement, not typing speed. Run a paid trial task. Most hires start within two to four weeks of the first call.
This guide walks you through all seven steps. You’ll get a job description template you can copy, eight interview questions worth asking, a two hour trial task with a scoring method, and a 30 day onboarding plan. Further down, you’ll find a side by side comparison of the three hiring routes, honest guidance on offshore time zones, and a checklist that tells you whether this hire suits your business right now.
Key takeaways:
- Your hiring route shapes results more than the hourly rate does
- A UK admin salary costs far more once National Insurance and pension land on top
- Three channels exist, and each suits a different size of business
- IR35 applies when you engage a contractor directly, not when you buy a service from an agency
- A paid trial task predicts fit better than any interview
How to Hire a Virtual Administrative Assistant: 7 Steps
Hiring a virtual administrative assistant in the UK takes seven steps, from a task audit through to a 30 day onboarding plan. Teambuild Consultancy, based in London, runs this same process for every admin VA placement.
Step 1: Audit your week and list the tasks
Track your work for two weeks before you speak to anyone. For every job that lands on your desk, write down five things: what it is, how often it arrives, which system it lives in, what it produces, and who owns it today.
That log becomes your brief. Without one, you’ll guess at the hours and get the size wrong in both directions.
Most UK business owners find 12 to 18 hours a week of work that needs no owner input at all. Inbox sorting, diary juggling, chasing paperwork and updating your CRM all show up fast.
Step 2: Decide part-time or full-time
Your task log answers this. Two options cover almost every UK business:
| Option | Weekly hours | What it realistically covers |
| Part-time | Around 20 | Diary, inbox, scheduling, basic CRM work and reminders for one leader |
| Full-time | 40 | Everything above, plus project coordination, supplier chasing, reporting and document control |
Under 20 hours of logged work means part-time. Above 30, go full-time from day one and skip the awkward middle.
Owners usually guess high on their first hire. Start where your log points, then grow. A dedicated model lets you move from part-time to full-time without running a fresh recruitment round.
Step 3: Choose your hiring route
Three routes exist in the UK: freelance marketplaces, UK based agencies, and dedicated offshore providers. Price isn’t the deciding factor. What matters is who carries the vetting, who covers sickness, and who holds the contract when something goes wrong.
Work through the full comparison in the next section before you commit. Then come back and finish the remaining steps, because they apply whichever route you pick.
Step 4: Write the job description
A vague advert brings vague candidates. Copy the block below and fill it in.
ROLE SUMMARY
One line on who you are and what the assistant will own.
RESPONSIBILITIES
- Diary and meeting scheduling
- Inbox sorting and drafted replies
- CRM record updates and data cleaning
- Invoice preparation and payment chasing
- Document formatting and filing
- Travel and accommodation booking
- Supplier and client follow up
- Weekly reporting against agreed measures
TOOLS REQUIRED
Google Workspace or Microsoft 365, Slack, Xero, your CRM, your project tool
WORKING HOURS AND TIME ZONE
Days, start and finish times in GMT, plus expected response window
REPORTING LINE
Who sets priorities, who signs off work
SUCCESS MEASURES
Day 30: owns diary and inbox without prompting
Day 90: owns two full workflows with written SOPs
Step 5: Screen and interview
Eight questions separate a strong candidate from a busy one. Ask all of them, in this order:
- Two urgent jobs land at once and you have one hour. What do you do first?
- An instruction arrives and you don’t understand it. What happens next?
- How do you handle private client information?
- Walk me through the CRM work you’ve owned before.
- Tell me about a problem you spotted before anyone asked you to look.
- Describe a job you got wrong and what you did about it.
- Send me a short email you’ve written for a previous client.
- Which UK hours can you cover every week without fail?
Listen to the reasoning, not the polish. Anyone who answers question one without asking who sent the work hasn’t done this job properly.
Step 6: Run a paid trial task
Pay for two hours of real work before you sign anything. One good test: hand over 40 CRM records and a source list, then ask for a clean merge with every mismatch flagged.
Score five things out of five:
- Accuracy against the source
- Speed against the two hour budget
- Questions asked before starting
- Exception handling on messy records
- Handback summary quality
Anyone scoring 20 or above handles real UK admin work. Scores under 15 mean you keep looking. This single test kills more bad hires than a second interview ever will.
Step 7: Onboard and set the review rhythm
Weak handovers break more placements than weak assistants do. Run a fixed 30 day plan.
- Week 1: grant tool access, share the preferences document, shadow your day
- Week 2: hand over supervised tasks with same day feedback
- Week 3: pass full ownership of two workflows
- Week 4: review against the measures from your Step 1 log
Your preferences document needs four things written down: how meetings get booked, the tone your emails carry, what gets escalated to you, and who’s allowed to interrupt your calendar.
Short on time for all seven steps? A UK virtual assistant agency handles the whole thing for you. Teambuild Consultancy screens the candidates, shortlists the best matches, runs onboarding, and carries the HR and payroll at our end. You review two or three people, pick one, and start working. That’s the difference between managing a hiring process and simply getting the help.
Where to Hire: Agency, Platform or Dedicated Provider
Three channels serve UK buyers, and each one trades price against risk. Teambuild Consultancy sits in the third group, matching UK firms with dedicated admin VAs from our London office.
Freelance marketplaces
You’ll pay the lowest hourly rate here. You also carry every other job yourself: vetting, onboarding, quality checks and data security. Nobody covers sickness or holiday. Turnover runs high, so many buyers repeat the hunt within a year.
UK-based virtual assistant agencies
These sit in your time zone and sell fixed hour packages, usually £25 to £40 an hour. Your virtual administrative assistant cost climbs quickly once your weekly hours grow. Many agencies also split one assistant across several clients, which dilutes the context they build about your business.
Dedicated offshore providers
You get one named assistant assigned to your account, plus managed vetting and replacement cover. Billing runs monthly rather than hourly. The contract sits business to business, so the provider handles employment matters at their end.
Which route suits which business
| Factor | Freelance platform | UK agency | Dedicated provider |
| Typical UK cost | Lowest hourly | £25 to £40 hourly | Fixed monthly |
| Vetting handled by | You | Agency | Provider |
| Cover if absent | None | Sometimes | Included |
| Continuity | Low | Medium | High |
| Compliance handled by | You | Shared | Provider |
| Best for | One off jobs | 5 to 15 hours weekly | Daily ongoing support |

Working With an Offshore Assistant Across Time Zones
Offshore assistants cover UK business hours when the provider builds shifts around GMT. Teambuild Consultancy places Philippines based admin VAs with UK firms on exactly that basis, coordinated from London.
How UK-hours cover works in practice
Your assistant starts and finishes on your clock, not theirs. That gives you a full working day of live overlap, so messages get answered while you’re at your desk. Set a response window in writing during onboarding. One hour suits most admin work.
When offshore is not the right fit
Some roles need a person in the room, and no shift pattern fixes that. Skip the offshore route when the job involves greeting visitors, handling physical post or original documents the same day, or fronting regulated UK sales calls where clients expect a local voice. Say so early and save everyone a wasted trial.
Is a Virtual Administrative Assistant Right for Your Business?
A virtual administrative assistant pays for itself when three or more of these apply to your UK business. Some firms advertise the same role as a virtual office assistant, so judge the duties rather than the job title.
- You lose 10 hours or more each week to admin
- Your inbox never reaches the bottom
- Meetings get missed because nobody owns the diary
- The same repetitive jobs return every week
- A UK salary looks hard to justify right now
- You run a property, accounting, medical or service business
Point five carries real numbers. HMRC charges employers National Insurance at 15% on earnings above the £5,000 secondary threshold, a rate that applies to every band above that point with no upper limit (GOV.UK, Rates and thresholds for employers 2026 to 2027). A £28,000 admin salary adds £3,450 in employer NI before pension, equipment or any Employment Allowance claim.

Frequently Asked Questions
How much does a virtual administrative assistant cost in the UK?
UK agencies charge £25 to £40 an hour. Freelance platforms charge less but add management work. Teambuild Consultancy in London bills a fixed monthly rate for dedicated support. Current figures sit on our pricing page.
What is the difference between a virtual assistant and a virtual PA?
UK providers use both labels for similar work. A virtual PA usually supports one leader’s diary and travel. A virtual administrative assistant covers wider business admin: CRM records, invoices, reporting and supplier chasing.
Do I need to worry about IR35 when hiring a virtual assistant?
IR35 applies when you engage a contractor directly. Buying a service from an agency creates a business to business contract instead, so off-payroll rules work differently. Confirm your own position with your accountant.
How many hours per week do I need?
Part-time at around 20 hours covers diary, inbox and scheduling for one person. Choose full-time at 40 hours once project coordination, reporting and document control join the list.
Can an offshore assistant work UK business hours?
Yes. Teambuild Consultancy assistants work shifts built around GMT, so you get live overlap through your whole working day. Agree a written response window during onboarding.
Is my client data safe with a virtual assistant?
You stay the data controller under UK GDPR. Sign a data processing agreement, use a password manager, and grant access only to systems the role needs. Reputable providers arrange these documents already.
How long does it take to hire one?
Most UK placements run two to four weeks from first call to start date. Agencies shorten that because candidates are pre-vetted. Direct hiring takes longer once you add advertising and screening.
What happens if the assistant is not the right fit?
Dedicated providers replace the assistant at no extra charge. Teambuild Consultancy handles rematching and the fresh handover. Freelance hires carry no such cover, so you restart the search yourself.
