Freelance rates in the UK: setting your hourly and day rate in pounds
Most rate advice reaches UK freelancers pre-converted: the formula in dollars, the cost lines American, the tax paragraphs about a system that is not yours. The formula itself travels fine — it is the same one this site's hourly rate calculator runs everywhere. What changes at the UK border is the inputs: a pension nobody else funds, National Insurance folded into your tax set-aside, an accountant's fee that is close to compulsory, a day-rate convention in contract work, and one conversation — IR35 — that US guides never have at all. This guide runs the whole chain in pounds, on UK cost lines, and keeps every tax statement hedged the way it should be: general guidance, with GOV.UK and an accountant as the authorities, never a ruling on your circumstances.
1. The worked example: one UK sole trader, priced properly
Take a freelance designer working as a sole trader. She wants to take home £45,000 in a year. Her costs — the UK list, detailed in section 2 — come to £6,500. She sets aside 25% for tax, takes five weeks off, works 40-hour weeks, expects 60% of her hours to be billable, and adds a 10% margin. Run the chain:
- income plus expenses: £45,000 + £6,500 = £51,500 needed;
- grossed up for the 25% tax set-aside: £68,667;
- with the 10% margin added: £75,533 to earn;
- 47 working weeks × 40 hours = 1,880 hours, of which 60% billable = 1,128 sellable hours;
- £75,533 ÷ 1,128 = £67 an hour — and the calculator's day figure, hourly × 8, is £536 a day.
Nothing in that chain is a market rate, a survey result or a recommendation. It is what this one practice's own numbers require, no more portable than her rent would be. Your chain belongs wherever your inputs put it — which is the whole method. What the UK changes is which lines feed it.
2. The UK cost lines the dollar guides don't carry
The pension is yours to fund. An employee's pension arrives with an employer's contributions attached; a sole trader's arrives when she pays it, or not at all. If retirement saving is going to happen, it is a cost line in the expenses — £2,400 of the £6,500 above — not something squeezed from whatever the rate happens to leave over. Treating it as optional is how freelancers end up well-paid at 40 and unfunded at 60.
National Insurance lives inside the tax input. As a sole trader you pay income tax and National Insurance on your profits through Self Assessment, and the rate formula's tax percentage is where both of them live while you plan: one set-aside figure — 25% in the worked example, the calculator's default — whose job is to make the January bill a transfer from a pot that already exists, not a raid on that month's income. The real mix depends on your profit level and your circumstances, and it is emphatically not this guide's job to compute it: GOV.UK publishes the current bands and rates, and an accountant can pin yours in a single conversation.
The accountant is nearly a fixed cost. Self Assessment makes the annual tax return a deadline with penalties attached, and most established sole traders hand it to an accountant — £900 of the example's expenses. The remaining lines are the familiar ones, priced in pounds: software and kit £1,500, professional indemnity and other insurance £700, home office, phone and internet £1,000. Total £6,500, every line checkable against a real bank statement — which is the test any expense list has to pass.
3. Day rates: the UK contract convention
A large share of UK freelance work — agency bookings, contract engagements, anything arranged through a recruiter — is quoted per day, not per hour. The day rate is not a separate species of number: it stands on the hourly rate exactly as day rates explained sets out, and the calculator's day figure is the hourly rate × 8. Run a second UK practice through the chain — a contractor who wants £60,000, carries £7,500 of costs (a £3,000 pension line, £1,600 of software and kit, £1,100 of accountancy, £800 of insurance, £1,000 of phone and workspace), sets aside 25%, takes six weeks off and bills 70% of a 40-hour week. The chain runs £67,500 needed, £90,000 grossed up, £99,000 with margin, earned across 1,288 billable hours: £77 an hour, £615 a day, over what works out to 161 billable days in the year.
Two judgements sit on top of the arithmetic. First, the × 8 headline assumes a day in which all eight hours bill; a focused day honestly holds nearer six billable hours for many kinds of work, which is why the day-rates guide treats × 6 to × 8 as the honest range and asks what the day actually contains. Second, a day rate buys exclusivity — a booked Tuesday cannot be sold twice — and UK buyers who book in days understand that, which is why the day is quoted as a day: half days priced as a stated fraction of it, never quietly re-split into hours at the hourly rate when the booking gets short.
4. Inside IR35, outside IR35: why the rate conversation changes
One conversation has no equivalent in the dollar guides. Some UK engagements — typically those arranged through agencies, or worked through a limited company — come with a determination that the engagement falls inside IR35, the off-payroll working rules; who makes that determination depends on the set-up, and it can be contested. The pricing consequence is what belongs here: inside IR35, income tax and National Insurance are deducted from your fee before you are paid, so the take-home a rate delivers is no longer the rate you quoted — and the same take-home therefore needs a visibly higher headline. Rerun section 1's designer with the tax set-aside at 35% instead of 25%, everything else untouched, and her £67 an hour becomes £77 an hour — £618 a day instead of £536. The work did not change, her costs did not change; the route the deductions take did. Outside IR35, you invoice the gross figure and run the set-aside yourself, as in section 2. Treat any single engagement's status as a question for GOV.UK's guidance and, where the money is real, an adviser's — the rules have changed before and a pricing guide is not the place a determination gets made.
5. VAT sits on top of your rate, never inside it
However the worked examples land, VAT is not one of their ingredients. You only ever charge VAT if you are registered for it: registration generally becomes compulsory once your taxable turnover passes the VAT registration threshold — £90,000 at the time of writing — and some freelancers register voluntarily below it, usually to reclaim VAT on their own costs. Thresholds change, so treat that figure as a signpost and check the current one on GOV.UK. If you are registered, the VAT is added on top of your rate and shown separately on the invoice — the rate itself stays the net figure the formula produced. If you are not registered, there is no VAT line and the rate simply stands alone. Our invoice generator for UK freelancers covers what a VAT invoice includes and is set up in pounds by default.
6. The billable share still runs everything
Strip the accents away and the biggest lever is the same one it is everywhere: how much of the week anyone pays for. Hold the section 1 designer's income, costs, set-aside and margin exactly still and move only the billable share. At 55% — 1,034 sellable hours — her rate must be £73 an hour. At 65% — 1,222 hours — it falls to £62 an hour. An £11-an-hour swing from nothing but the shape of her week, which is why freelance rates by experience level argues that experience shows up in the maths mainly here: fewer corrections, less unbilled thinking-for-free, more of the week sold. The UK lines decide what your rate has to cover; the billable share decides how thinly it gets spread.
