The day rate looks glorious from the inside of a salaried job. £350 a day, twenty days a month, and suddenly you're earning more than your manager - on paper. The maths only works once you've subtracted the things your employer quietly paid for: holiday, sick pay, your pension contribution, the gaps between contracts, and the accountant you now need. Going freelance can absolutely pay off, but only if you cost it honestly first.
Day rates versus salary
A useful rule of thumb is that a contractor needs a meaningfully higher headline figure than a salaried equivalent just to break even, because so much shifts onto your shoulders. Typical day rates vary enormously by sector and region - a junior freelancer in a quieter market might see £150 to £250 a day, while an experienced specialist in tech or finance in London could command £400 to £700 or more. Treat any figure as approximate and check what your specific field actually pays before you hand in your notice. And remember you won't bill 365 days; once you take off holidays, illness, admin, and the inevitable dry spells, billing 200 days in a year is a respectable result, not a failure.
Finding your first clients
Your first client is very often your last employer, or someone in your existing network. Before you leave, have at least one piece of work lined up - leaping with nothing booked is brave and occasionally ruinous. After that, the work tends to come from referrals, repeat business, and being visibly good at one specific thing rather than vaguely available for anything.
Tax, National Insurance and insurance
This is the part people underestimate, so commit to getting it right from day one. Register with HMRC, set aside a chunk of every invoice for tax and National Insurance the moment it lands, and get an accountant if your situation is anything beyond simple. Sort out professional indemnity and public liability insurance before you take on client work, not after something goes wrong.
- Open a separate business bank account so your money and the taxman's money never sit in the same pot.
- Decide early whether you'll work through a limited company or an umbrella - it affects your tax and your IR35 position.
- The freedom is real, but so is the silence when a contract ends and nothing has replaced it yet, so build a financial buffer before you start.
The trade-off is honest: you swap security for control. Some weeks that swap feels like the best decision you ever made. Some weeks you'll miss being able to be ill without losing money.
