Limited Company vs Sole Trader for Trades: Which Protects You?
The real difference is liability: a limited company is a separate legal person, so if a job goes disastrously wrong the company carries the loss - a sole trader carries it personally, house and all. But insurance, not company structure, is what protects you day to day. Here's how to weigh protection, tax and admin honestly.
The liability difference - what it really means
Trade work carries physical risk: a fire traced to a rewire, a flood from a botched connection, a wall that shouldn't have come down. As a sole trader, you and the business are legally the same - a claim that outruns your insurance can reach your savings and your home. As a limited company, the company signs the contracts and carries the liability; your personal assets sit behind the corporate veil.
The honest caveats
- Insurance is the real day-to-day protection - public liability cover pays claims long before company structure matters. No structure replaces proper cover.
- Directors can still be personally liable for their own negligence - the veil is protection, not immunity.
- Personal guarantees - banks and some suppliers ask directors to guarantee borrowing, which puts personal assets back on the line for those debts.
The tax picture
Sole trader
Income tax and National Insurance on profits, one Self Assessment return, and the option of the cash basis - counting money when it actually moves. Simple, cheap to run.
Limited company
The company pays corporation tax at the 19% small profits rate or 25% main rate, and you pay dividend tax on what you draw beyond salary. At lower profits the savings over sole trader rates are often thin once accountancy fees are counted; as profits grow the company route typically improves. Run your real numbers with an accountant rather than trusting a rule of thumb.
The admin cost
- Annual accounts and a confirmation statement filed at Companies House - publicly visible, including roughly what the business made
- A corporation tax return on top of your personal one
- Payroll if you take a salary; dividend paperwork if you take dividends
- An accountant is near-essential - budget for the fee
From the tools: A joiner my brother subs alongside in Leeds stayed sole trader for years - until he took on a £45,000 barn conversion where a structural mistake could have meant a six-figure claim. He incorporated before signing, mostly for the liability backstop, and the client actually preferred contracting with a limited company. The unglamorous truth: in four years the company has never been tested on liability, but his £5 million public liability policy was - a ceiling collapse claim settled at around £12,000, paid entirely by the insurer. The Ltd costs him about £1,000 a year in accountancy that the sole trader version didn't. He calls it the cheapest sleep he buys.
Quick answers
Does a Ltd protect my personal assets?
Largely yes - the company carries the liability if a job goes badly wrong. But directors remain liable for their own negligence, personal guarantees pierce the protection for borrowing, and insurance is what handles real-world claims.
Is a company cheaper on tax?
Corporation tax (19% small profits, 25% main) plus dividend tax can beat sole trader rates as profits rise - but accountancy costs eat into it. Compare on your actual figures.
How much extra admin?
Companies House filings (public), a corporation tax return, payroll and dividend paperwork. Sole traders file one Self Assessment and can use the cash basis.
Should a one-man band incorporate?
Usually only when profits climb, clients demand it, or the damage potential on your jobs makes the liability backstop worth the admin. Well-insured sole trader simplicity wins early on.
