Side Hustles & Self-Employment

Civil servants face stricter outside employment rules than almost any other group of UK employees. The Civil Service Management Code requires prior approval before accepting outside employment that might affect civil service work — not just work that definitely creates a conflict, but work that might. The threshold is lower than in most private sector […]

Home baking is one of the few side hustles where the skills come before the business idea. Most people who start a home baking hustle have been baking for years — they already know they are good at it. What they are less clear on is the legal framework, because baking to sell is treated […]

Dog walking is one of the most accessible service-based side hustles in the UK — low startup cost, no qualifications legally required, no fixed hours, and a market that continues to grow as pet ownership rises and more people return to office-based work. The UK had an estimated 13 million pet dogs in 2025 and […]

Most paid survey sites in the UK are not worth spending serious time on. The problem is not usually whether they pay at all. It is how much time disappears into screening questions, disqualifications, low-value surveys and payout thresholds before the money actually reaches you. Once those factors are included, many conventional survey panels work […]

Cashback apps are the most passive form of side income available in the UK. You spend money you would have spent anyway on groceries, insurance, broadband, travel and receive a percentage back. No skills required, no clients, no schedule, no inventory. The honest caveat: cashback is supplementary income, not a side hustle in the entrepreneurial […]

HMRC’s penalty system for Self Assessment has two separate tracks that run simultaneously: late filing penalties (for not submitting your return on time) and late payment penalties (for not paying the tax owed on time).

The threshold — £90,000 of taxable turnover in a rolling 12-month period — puts VAT registration firmly in the territory of a full-time business rather than a supplementary income stream.Someone tutoring for £2,000 a year, reselling clothes on Vinted for £3,000, or doing occasional […]

Since April 2024, the landscape of National Insurance for self-employed people has changed fundamentally. Class 2 NIC — the flat weekly charge that sole traders paid for decades — was abolished for most self-employed people. Class 4 NIC remains and was reformed at the same time.

Claiming allowable expenses reduces your taxable profit — which directly reduces your tax bill. For a side hustler on a 20% basic rate paying 6% Class 4 NICs, every £100 of legitimate expenses claimed saves approximately £26. For a higher-rate taxpayer, the saving is approximately £46 per £100. The rule that governs all expense claims […]
