The Real Cost of Hiring an Employee vs a Virtual Assistant
A full-time UK office admin costs £35,934 in year one once you add employer National Insurance, pension contributions, recruitment fees, sick pay exposure and kit. A Zero Chaos Club virtual assistant starts from £9,000 a year, with none of those costs attached.
You put "office admin" in the job spec and budget for £13 an hour. That number is the least useful figure in the whole decision.
Most trades and construction business owners price a hire off the hourly rate, then get blindsided six months in when the actual cost of having someone on payroll shows up in a dozen different places. Here's what actually lands on your books in year one, based on the 2026/27 National Living Wage, current employer NI thresholds and UK average recruitment costs.
How much does hiring an office admin actually cost in the UK?
Base pay.
National Living Wage, 37.5 hours a week: £24,785 a year. That's before anything else touches the payslip.
Employer National Insurance.
15% above the £5,000 threshold. Add £2,968.
Pension contributions.
3% auto-enrolment minimum. Another £556.
Recruitment and onboarding
UK average cost per hire is £6,125. That's the job ad, the interviews, the time you spent doing both instead of running jobs.
Statutory sick pay.
Day-one entitlement from April 2026. Up to £123 a week, and you're covering it whether the job's on track or not.
Kit, licences, desk space.
Laptop, software, insurance, a corner of the office that used to be storage. £1,500 a year, conservatively.
Add it up and a full-time office admin costs £35,934 in year one. Not £24,785. £35,934.
The bit that never makes it into a hiring decision.
None of that includes the ramp-up. A new admin hire takes weeks to learn your suppliers, your job numbering, which subcontractor never answers the phone before 9am. You're paying full wage for someone who isn't yet doing the job you hired them for.
It doesn't include turnover either. Admin roles in small construction firms don't tend to stick. Someone leaves after 8 months and you're back at the £6,125 recruitment line, plus another 6 weeks of ramp-up, plus whatever slipped through while the desk was empty.
Then there's the gap while you're recruiting. A lot of owners bring in a recruitment agency to cover the desk while the search runs, sometimes weeks, sometimes a couple of months. That's a day rate on top of everything above, for someone who's also learning your business from scratch and will be gone the moment the permanent hire starts. You end up paying twice to fill one seat.
And it doesn't include the management time. Someone has to set the tasks, check the work, sort out the software log-in that's stopped working. That's your time, and it isn't free either, even if it never appears on a spreadsheet.
How much does a virtual assistant cost compared to an employee?
A Zero Chaos Club VA starts from £9,000 a year.
No National Insurance, no pension contribution, no sick pay exposure, no recruitment fee, no kit to buy.
You get a laptop, software and insurance already sorted, nothing to provide. When there's no work for a stretch, you're not paying for downtime. If your needs change, you're looking at a month's notice, not a redundancy process.
That's not a like-for-like swap. A VA isn't sat in your office answering the phone at 8am. The job is taking the admin off your plate: chasing suppliers, scheduling, invoicing, keeping the paperwork moving so a quote doesn't sit unsent for a week. For a lot of trades businesses, that's most of what the office admin role was actually for.
The mental load nobody prices in.
If you're quoting jobs on a Sunday night because nobody chased the paperwork Monday to Friday, the problem isn't your team. It's that the admin has nowhere to live during the week, so it lands on you, after hours, when you're too tired to do it properly.
And it doesn't stop when you're home. You sit down for dinner, your body's at the table, your mind's still on site. Cash flow is the one that keeps a lot of builders up, you're on thirty-day terms with the client, but your suppliers and your labour want paying next week, and you're the one stuck in the middle finding the gap. The second is the mental load. A sales meeting in the morning, quoting in the office by lunch, twenty or thirty calls off the guys on site by the afternoon, then the invoices and the numbers on top of all of it. That's a normal Tuesday, not a bad week.
Add in the labour that's hard to pin down, the supplier who's late and knocks on to every trade behind them, the client whose expectations shift halfway through the job, and you can see why the list never actually finishes. Ask any builder running their own company what their two biggest headaches are and you'll get an answer in under five seconds. That's how close to the surface it sits.
Hire the right admin support and some of that moves off your plate for good. Quotes go out the day they're due, not the day you finally get to them. Suppliers get chased on a Tuesday afternoon, not a Sunday night. You still carry cash flow and the guys on site, that's the job, but the paperwork stops eating the hours that should be yours.
