The Cost of Knowing Better: How Poor Mental Health Puts Small Businesses at Risk

employer costs preventative mental health sickness absence small business Nov 01, 2026
In brief

Poor mental health costs a small business in six places, through absence, friction between colleagues, losing good people, new legal risk, missing support and clients who take their business elsewhere, and most of that cost arrives long before anyone takes a day off sick. Becky Farrell, founder of CLEVRA, a preventative workplace mental health programme, sets out where the cost sits, why helplines, apps and one-off sessions don't reach the cause, and what prevention looks like when it is built into how a small team works.

When pressure looks like commitment

At year end, someone on the commercial team is working 18-hour days, trying to please everyone, pleasing no one, and least of all themselves, while sales push hard to get deals signed off before the deadline. I saw this many times over the years, and nobody sees the moment when pressure like this becomes a mental health issue, because from the outside it looks like commitment.

In a small business that person is often the one who knows your biggest client or keeps a project on track, so when their judgement slips under pressure, the cost shows up in your revenue, your clients and your reputation long before anyone takes a day off sick.

Most small business owners I speak to already know poor mental health costs them something, but very few have seen where the cost actually sits, because it never arrives as one bill, it turns up in six different places, and most of them look like ordinary business problems until you trace them back.

01

One person off is felt by the whole team

In a large organisation someone off sick for a month is covered by a department, but in a team of 12 it means a client relationship without its owner, a project without its lead, and everyone else absorbing extra work, often until the next person starts to struggle.

HSE figures show each case of work-related stress, depression or anxiety cost an average of 22.9 working days in 2024/25, more than four working weeks, and since April 2026 every one of those days carries Statutory Sick Pay from the first day of absence.

02

Friction between colleagues wears down confidence, and it costs money

I once watched someone get a promotion she had worked hard for, and a colleague who didn't like the decision started to make life difficult for her. It was light touch, a comment here and being left out of a conversation there, nothing anyone would have taken to HR, but over time it wore down her morale and her confidence, and with them the way she did her job.

Acas estimates workplace conflict costs UK organisations £28.5 billion a year, more than £1,000 for every employee, and of the people who experienced conflict, 56% reported stress, anxiety or depression and 40% said they were less motivated at work. In a small business, where people work closely and there is often no HR team to spot it, light-touch behaviour can carry on for months before anyone names it.

03

Losing good people costs far more than their salary

When someone leaves because the pressure became too much, you lose their knowledge, their relationships and sometimes their clients, and then you pay to replace them.

The government's Keep Britain Working review found recruitment costs exceed £11,000 for each replacement, before you count the months it takes a new person to get up to speed, and Acas estimates around 485,000 people resign every year because of conflict at work.

04

The law now asks more of small employers

Two changes have brought mental health much closer to the small business owner's desk. Since April 2026, Statutory Sick Pay has been payable from the first day of sickness, so every short absence now has a direct cost, and from 1 January 2027 employees can bring an unfair dismissal claim after six months' service rather than two years, with the cap on compensation removed.

The HSE has also increased its focus on work-related stress, which reached a record high in 2024/25, and it expects employers to manage stress as a risk in the same way they would manage any other hazard at work.

05

Small businesses carry the same risk with far less support

Large organisations have HR teams, occupational health and an employee assistance programme, and most small businesses have none of them. A government survey of employers found 92% of large employers provided occupational health services compared with 18% of small employers, and a 2026 Work Foundation study found more than a quarter of the smallest employers offer no health support at all.

Owners tell me they rely on knowing their people well, which is a strength, although knowing someone well is not the same as knowing when pressure has turned into something more serious.

I watched another colleague get promoted into a senior account director role at the same time as she was paying for a wedding, while her partner had been made redundant and had no desire to go back to work. She was proud of the promotion and she was carrying all of it, and none of that pressure stayed at home when she walked into the office.

In a 2025 survey for the CIPD, 31% of employees said money worries had affected their work performance, through lost sleep, stress and finding it hard to concentrate, and in a small business with no HR team, the owner is often the only person in a position to notice.

Clients notice before you do

Clients don't see your team's workload, they see the reply that took three days instead of one, the account manager who sounds flat on the phone, and the small promises that stop being kept.

When the HSE asked workers what caused their work-related stress, depression or anxiety, the most common answer was workload, including tight deadlines and too much responsibility, the same pressure a client-facing person in a small business carries every day. By the time a client mentions it, they have usually been thinking about it for a while, and some will go elsewhere without ever telling you why.

Why don't helplines, apps and mental health first aid reach the cause?

When small businesses do act, it is usually with something borrowed from larger organisations, such as a helpline number, a mental health first aider, a resilience session or a wellbeing app. None of these are bad things, but most of them are designed to respond once someone is already struggling, rather than to stop the pressure building in the first place.

In 2024, Dr William Fleming at the University of Oxford's Wellbeing Research Centre studied more than 46,000 UK workers across 233 organisations and found no evidence that individual-level offers such as mindfulness, resilience and stress management sessions, relaxation classes and wellbeing apps made people any better off than colleagues who didn't take part. His conclusion was that organisations have to change the workplace and not just the worker.

Mental health first aid has its place, but a first aider is trained to respond, reassure and signpost someone towards help, so the conversation usually starts once something has already gone wrong. In a small business, where the owner is often the first aider, the manager and the person setting the deadline, I think this is a lot to ask of one role.

What does preventative mental health look like in a small business?

Prevention is the seatbelt, not the ambulance.

It means building really strong foundations while people are feeling well, so when the pressure arrives, and in a small business it always does, people already understand themselves and each other well enough to talk about it.

Prevention would not have made that year end any easier, because the deadlines were real and so was the pressure, but it would have changed how people worked through it together. When people understand themselves and the people around them, communication improves and there is less of the friction that adds to the pressure everyone is already under. It gives someone the space to reframe the work in front of them, to recognise what they can and cannot control, and to set boundaries they can explain to their manager and their colleagues without feeling they are letting anyone down.

Prevention also means people have somewhere to go long before they need a mental health first aider, a colleague close by who has done the work on their own self-awareness and can offer a space for good quality listening, rather than trying to fix the problem or signpost someone on.

How does CLEVRA work in a small business?

CLEVRA is a preventative workplace mental health programme with eight steps, and everyone in the business goes through the same programme, from the owner to the newest starter. Each step helps people understand something about themselves, such as their values, their strengths and what they need to stay well, and by the end each person has their own personal guidelines, including the early warning signs that tell them pressure is building.

Around one in ten people become CLEVRA allies, so there is always someone close by who will really listen rather than rush to fix the problem or signpost someone on. Because allies have worked through the whole toolkit themselves and taken it further with their own coaching, they know it well enough to point a colleague towards the part of CLEVRA that will help, so that person can do the same work for themselves.

For a small business owner, this means each person takes their guidelines to their manager, so you can see when someone is overstretched rather than mistaking it for dedication.

Protecting revenue, clients and people

Every small business owner I speak to already knows their people are their business, and most already know poor mental health is costing them something. The cost of knowing better is what happens when that knowledge stays on the shelf, a deal that slips, a client who goes elsewhere, a good person who leaves, or a claim that could have been avoided.

Protecting your revenue, your clients and your people starts in the same place, with people who understand themselves well enough to speak up while a problem is still small enough to fix.

A note from Becky

I spent more than 20 years in corporate sales, and I saw the year-end pressure, the light-touch bullying and the weight people carry in from home play out many times over the years, usually with nobody noticing until it was already costing the business. If something in this article sounded like your business, I'd be happy to talk it through.

Frequently asked questions

How much does poor mental health cost UK employers?

Deloitte puts the cost at £51 billion a year, and almost half of it comes from people who are at work but not well enough to do their job well. In a small business the cost usually shows up as slipped deals, slower replies to clients and good people leaving, long before it appears as sickness absence.

Is mental health first aid enough for a small business?

Mental health first aid has its place, but a first aider is trained to respond and signpost once something has already gone wrong. Becky Farrell, founder of CLEVRA, argues small businesses need preventative work first, so people understand themselves well enough to speak up while a problem is still small enough to fix.

What is a preventative workplace mental health programme?

A preventative workplace mental health programme builds mental health foundations while people are well, rather than responding once they are struggling. CLEVRA is an eight-step programme in which everyone, from the owner to the newest starter, works out their values, strengths and needs, and leaves with personal guidelines that include their own early warning signs.
