How many hours does admin really cost a small team, and how do you count them honestly?

Admin costs the average UK small business owner 11 hours a week, and in a team of three to twelve people the true total is usually higher, because the work is spread across everyone. Counting it honestly means tracking real tasks for a week, adding up the whole team, and valuing each hour at what it would cost to delegate, which Simplish AI puts at £15. This guide shows the method and a worked example.

How many hours a week does admin take in a UK small business?

UK small business owners average 11 hours a week on admin and finance tasks, according to the SME Business Barometer from American Express and Small Business Saturday UK (2026). That figure covers the owner alone.

It does not include the hours your office manager spends chasing invoices, or the time a team member loses retyping job details from one system into another. In a small business those hours are real, and they are rarely written down anywhere.

Why count across the whole team, not just the owner?

Admin in a small business settles on whoever cares most, which is often not the owner. Counting only your own week misses most of it.

At three to twelve people, the same task is often done by several people in slightly different ways. Many of those tasks are processes that only exist in somebody's head. Nothing can be delegated or automated until it has been described, so the first job is simply to see it.

What are the six everyday admin drains?

Six tasks account for most recoverable admin in a small business. Individually each looks too small to mention; together they are the problem.

1. Chasing invoices. Forty minutes chasing one payment, and the awkward email that keeps getting postponed.
2. Retyping between systems. The same fields copied from one platform into another, by hand.
3. Quotes written from scratch. The quote your business has written ninety times, rebuilt again from a blank page.
4. Booking back and forth. Three emails to land one meeting, multiplied across everyone's diary.
5. Follow up that never happens. Leads go cold because nobody got round to the second message.
6. The nine o'clock inbox. The admin that waits until the end of the day, because it is nobody's actual job.

How do you count admin hours honestly?

Count one ordinary week, task by task, for every person who does admin, and write down how often each task happens and how long it takes. Estimates made from memory are almost always wrong, usually in both directions.

Ask each person to keep a simple log against the six drains for five working days. Record the task, how many times it happened, and roughly how long each took. Round down when unsure. Leave out work that genuinely needs human judgement, such as pricing a complex job, and count only the repetitive part around it.

What is an hour of admin worth?

An hour of admin is worth what it would cost to delegate it, which we put at £15 an hour. It is never worth your own charge out rate.

Valuing admin at your charge out rate makes the numbers large and wrong. You cannot bill a client for an hour you spent chasing an invoice, and if you delegated that task you would pay an administrator's rate, not your own. I chose £15 because it is a deliberately conservative, honest reflection of what it actually costs to hire someone to clear those "drain" tasks off your plate. It's a number you can take to your accountant and defend; anything higher is just ego, and ego doesn't clear the backlog.

How does the 48 week maths work?

Multiply the weekly hours by 48 working weeks, then by £15. One hour a week is 48 hours a year, worth £720. Five hours a week is 240 hours a year, worth £3,600.

We use 48 weeks to allow for holidays and bank holidays. Full time workers in the UK are entitled to 5.6 weeks of paid holiday a year (GOV.UK), so if your team takes all of it, your own figure may be slightly lower.

What does a worked example look like?

Here is the method applied to an illustrative six person business. These are example figures, not a client.

That is 600 hours a year, or about 86 working days at seven hours a day. The owner's share alone would look modest, which is exactly why counting the whole team matters.

Which of those hours can you actually get back?

Not every admin hour is recoverable. Some tasks need a person, some only need a simpler process, and some can be handed to software you already own.

Separating the recoverable hours from the rest is what a good AI readiness assessment is for. The £997 assessment does that task by task, and the report will identify at least 5 hours a week you and / or your team could get back, or you receive a full refund. For a business anywhere near the average, five is a floor, not a stretch.

What is the fastest way to count your own hours?

If a week of logging sounds like more admin, two quicker routes give you a starting number in minutes.

The Hidden Hours Score takes 16 questions and about three minutes. It gives you a total for the week, broken down across the six drains, ranked so you can see which three to tackle first. The admin cost calculator takes three numbers, how many people do admin, how many hours each, and your delegation rate, and turns them into hours, days and pounds a year.

Who is this guide for, and who is it not for?

This guide is for owners of businesses with three to twelve people who suspect admin is eating more of the week than anyone admits. It is especially useful if the hours are spread across a team rather than sitting with you.

It is not for solo freelancers, where the counting is simpler, or for larger firms with an operations team already measuring this. Nor is it a productivity method: the aim is a number you can act on.
