Admin costs UK small businesses around £25,000 a year per person

If you run a small UK service business, the median person on your team spends around 10 hours a week on admin. At a sensible blended rate of £55 an hour, across the 46 working weeks of the UK year, that is £25,300 a year per person, gone to admin. A team of three: over £75,000. A team of five: £126,500.

Most owners never put a number on it. Once you see it written down, it is hard to unsee.

Here are the five biggest time sinks for general UK service businesses, the AI tools that solve them, and three quick wins you can try this week.

The numbers behind the headline

The maths is simple and you can do it on the back of a napkin. Take your weekly admin hours, multiply by your hourly rate, then multiply by 46 (the UK working year after holidays and bank holidays).

• 10 hours × £55 × 46 = £25,300 per person per year
• 6 hours × £40 × 46 = £11,040 per person per year
• 14 hours × £75 × 46 = £48,300 per person per year

Your number will differ from the median. Run your own numbers in the calculator if you want a personalised figure. The 10-hour benchmark comes from HoursBack assessment data (n=20+) cross-checked against published UK SME productivity research.

Top 5 time sinks for general service businesses

1. Email triage and replies. The average owner-operator spends 90 minutes a day in their inbox. Most of those replies are repeats: same questions, same context, same answers. AI drafts can take the first pass and you approve in 30 seconds.

2. Meeting notes and action items. Each one-hour call generates 15 to 20 minutes of admin afterwards: typing notes, sending follow-ups, scheduling the next step. Done across a typical week, that is 2 to 3 hours of pure overhead.

3. Quote and proposal writing. Even a "quick" proposal eats 45 minutes by the time you have pulled in the right copy, costed it out, and sent it across. A handful a week and you have lost half a day.

4. Chasing payments and replies. The polite-but-firm follow-up email is one of the highest-friction tasks in a service business. Owners delay it because it feels awkward, then end up writing it badly because they are rushing.

5. Scheduling and rescheduling. Five minutes a booking, ten if it slips back and forth. A team that runs 30 bookings a week spends 3 hours just on the diary dance.

3 AI tools that solve them

ChatGPT (Team or Plus, around £18-£23 a month per seat) - the everyday workhorse. Inbox drafts, meeting prep, summarising long emails, drafting proposals from bullet points. Use the Team plan if you handle any client-confidential data. Suits any owner who writes more than 10 emails a day.

Otter.ai (around £8-£25 a month) or Zoom Pro (which now includes cloud recording and transcripts built in) - records your calls, gives you the transcript and action items within minutes. The action-item extraction alone is worth the subscription. Suits anyone who runs more than three video calls a week.

Make (around £8-£25 a month) - the wiring underneath. Connect your inbox, your calendar, your accounting software, and your client tools so the same job does not get re-keyed across four screens. Suits owners who can spend a Saturday morning setting it up once and reaping the rewards every week after.

Quick wins to try this week

1. Set up three saved ChatGPT prompts for your three most-repeated email types. "Polite chase for an overdue invoice." "Reply to a new enquiry confirming next steps." "Decline a pitch without burning the bridge." Paste in the email you received, hit send. Edit, then ship. Time saved per email: 4 minutes. Across 30 emails a week, that is 2 hours.

2. Turn on transcription on every internal and client call this week. Use whichever tool fits (Otter.ai, Fireflies.ai, or your Zoom Pro built-in). At the end of each call, copy the action-item list into your project tool. Stop typing notes during the conversation.

3. Take your 10 most common diary slots and put them in a booking link (Cal.com is free for solo users). Send the link instead of negotiating times by email. One booking that takes 5 minutes by email takes 30 seconds by link.

What an Assessment unlocks

The calculator and these tips are a starting point. They tell you the size of the problem and give you three things to try this week. They do not tell you the specific sequence of changes for your business, which tools to keep, which to scrap, or how to roll any of it out to a team without breaking what already works.

An AI workflow assessment does. We run a 60-minute interview, produce a custom 48-hour report with named tools, exact steps, and a 7-day plan, and back it with a money-back guarantee if we do not surface 5+ hours a week. £799.
