Business blind spots: what happens to your business if you're ill or die?

You're in good company

The government's Business Population Estimates for 2025 count about 4.27 million UK private sector businesses with no employees, out of about 5.69 million in total. That's roughly three in every four. So most of us running a business have no back-up person at all.

I've spent 35 years across property, software, finance and healthcare, and I've seen what happens when critical knowledge lives in one person's head. The business struggles, and so does the family left trying to untangle it. Death is guaranteed, but chaos is optional.

What happens depends on how your business is set up

This is general information for England and Wales. Your accountant or solicitor can tell you how it applies to you.

• Sole trader: you and your business are legally the same. gov.uk says sole traders are personally responsible for all of the debts of the business. If you die, your business money, assets and debts become part of your estate, and your personal representative (your executor) deals with them. They may also need to complete a Self Assessment tax return for the income you earned before you died.
• Partnership: under the Partnership Act 1890, a partnership is dissolved by the death of a partner unless the partners have agreed otherwise. A written partnership agreement matters.
• Limited company: the company carries on as a separate legal person, but someone still has to run it. If you're the only director and shareholder, the standard model articles let the personal representatives of the last shareholder appoint a new director. Check which articles your company actually uses.
• VAT and business taxes: gov.uk's Tell Us Once service passes a death on to HMRC for personal tax, but it says to contact HMRC separately if the person owed business taxes like VAT. Anyone taking over the VAT responsibilities of someone who has died, or who is too ill to manage their affairs, must tell HMRC within 21 days.

Illness is the blind spot most people forget

We tend to plan for death and forget about the far more common problem: being alive but unable to work or make decisions for a while.

A lasting power of attorney (LPA) for property and financial affairs lets people you choose make financial decisions for you if you can't. The Office of the Public Guardian's own guidance says you can make two of these LPAs: one for your personal finances and one for your business affairs, with different attorneys if you want. That way, the person who understands your business looks after the business.

Without an LPA, your family may have to apply to the Court of Protection to become your deputy. gov.uk lists a £432 application fee, a further £266 if a hearing is needed, and an annual supervision fee once appointed. If you run a limited company, ask a solicitor how an LPA works alongside your role as a director and shareholder.

For short-term help, Citizens Advice explains that many banks offer a third party mandate, which lets someone else operate an account for you. Ask your bank what it offers for business accounts.

The eight blind spots to check

In my Business Blindspots workshop, people score themselves from 0 to 10 on eight areas. Zero means it's only in your head. Ten means it's written down, shared and usable today by a named person.

1. Who steps in? Name the person, tell them, record their contact details and be clear about what they can decide. A willing friend isn't enough if they don't know it's them.
2. Money and deadlines: banking, invoices, bills, payroll, tax dates, insurance and renewals. Record where things are held, without sharing access unsafely.
3. Clients and current work: live jobs, client contacts, promises, deposits and deadlines, so someone can see what needs attention first.
4. How the work gets done: the routines, suppliers, templates and odd little workarounds only you know. Start with the jobs that would cause the most trouble if missed.
5. Passwords and access: devices, business email, software, passkeys, recovery codes and two-step verification. A list of passwords alone can still leave someone locked out.
6. Legal documents and authority: business structure, insurance, contracts, LPAs and company documents. Willing isn't the same as legally able to act.
7. Online business and digital assets: website, domain names, social accounts, cloud files, digital products and online income, with who owns each and when it renews.
8. Your 'next steps' plan: should the business continue, pause, be sold, transfer or close? What are the first urgent actions?

Number 1 names who steps in. Number 8 gives that person the plan to follow.

Your one-page 'if I'm unavailable' sheet

If you do nothing else, write one page and tell your named person where it is. Include:

• who steps in, and who to call first (accountant, bank, insurer, key clients)
• the five most urgent things in the first week, such as client updates, payments due and bookings to move
• where your fuller notes, contracts and logins map are kept
• whether you'd want the business paused, continued, sold or closed

Remember that client details are personal information. The ICO says organisations that use personal information, including sole traders, must pay a data protection fee unless they're exempt. Whoever steps in should handle client data with care.

Quick wins for this week

• Choose your 'steps in' person and have the conversation.
• List every renewal date: domain, website, insurance, software.
• Check your domain name and social accounts are in your name, with up-to-date recovery details.
• Add a second admin to your business social pages, if the platform allows it.
• Book time with your accountant or solicitor to ask: 'What happens to my business if I'm ill or die?'

When to see a solicitor or professional

• A solicitor: your will and business assets, a separate business LPA, partnership or shareholder agreements, and your company's articles.
• An accountant: tax, VAT, payroll, and what your executor would need to file.
• An insurance broker: cover such as income protection or key person insurance.
• A regulated financial adviser: pensions, investments and business succession.

I'm the affordable first step before those appointments. You'll arrive organised, with better questions, and spend less of your paid time on the basics.
