Introduction: Why Time Tracking Matters for UK Freelancers
If you’re a freelancer or sole trader in the UK, your time is quite literally your income. Yet most of us are hopeless at knowing where it actually goes. You sit down to invoice a client and can’t remember whether that project took six hours or sixteen. You undercharge, your effective hourly rate quietly collapses, and you promise to track your time properly “next month.”
Good time tracking software fixes this — and the right tool can also help you spot unprofitable clients, back up your invoices, and keep clean records for Self Assessment. But the market is crowded, pricing has shifted in 2026, and “free” doesn’t always mean what it used to.
This guide cuts through it. We’ve compared the tools that genuinely make sense for UK freelancers and small businesses, with honest pricing in pounds (and the dollars they’re actually billed in), so you can pick the right one without wasting an afternoon on trials.
What to Look For in a Time Tracker
Before the recommendations, here’s what actually matters for a freelance or small-business setup:
- A capable free plan or low entry cost — you shouldn’t pay a fortune to track your own hours
- Simple, fast tracking — if it’s fiddly, you won’t use it (the graveyard of abandoned time trackers is vast)
- Billable rates and reporting — to turn tracked hours into accurate invoices
- Invoicing — nice to have built in, though many freelancers use separate accounting software
- Cross-platform apps — desktop, mobile, and browser
- Honest pricing — watch for tools that bill in US dollars (so your cost moves with the exchange rate) or add usage-based fees on top of the headline price
A quick note on currency: the three tools below all price in US dollars, so the pound figures are approximate conversions that shift with the exchange rate.
The Best Time Tracking Software for UK Freelancers in 2026
1. Clockify — Best Free Plan and Best on Budget
Clockify has long been the go-to free time tracker, and it’s still the most budget-friendly option — but there’s an important 2026 change to know about.
Free plan: In April 2026, Clockify cut its free plan back. It’s now capped at 5 users (previously unlimited), though it still includes unlimited projects and core time tracking. Some features — billable rates, invoicing, and certain exports — moved to paid plans. For a solo freelancer, the free plan is still genuinely useful; just don’t expect the “unlimited everything” tier of old.
Paid plans: Clockify remains the cheapest of the big three. Paid tiers (billed annually) run roughly:
- Basic — $3.99/seat (about £3)
- Standard — $5.49/seat (about £4.50) — adds invoicing and QuickBooks integration
- Pro — $7.99/seat (about £6.50) — adds profitability and scheduling
- Enterprise — $11.99/seat (about £9.50)
Best for: Freelancers on a tight budget, and anyone who wants the lowest-cost paid plans as they grow. If cost is your main concern, Clockify wins.
2. Toggl Track — Best for Ease of Use
If you’ve tried time tracking before and given up because it felt like extra admin, Toggl Track is the one that tends to stick. It’s the most polished and frictionless tracker here — one click to start, one to stop.
Free plan: Up to 5 users, with no time limit. Unlimited time tracking, basic reporting, and 100+ integrations via the browser extension. For a solo freelancer, it’s genuinely capable at zero cost.
Paid plans: Toggl bills in US dollars, with a discount for annual billing (three months free):
- Starter — $9/seat (about £7) on annual billing, $12 monthly — adds billable rates, project budgets, and alerts
- Premium — $14/seat for the first year (then $18), $20 monthly — adds profitability, scheduling, and approvals
- Enterprise — custom
Best for: Freelancers who want a beautiful, fast, no-nonsense tracker and will actually use it every day. The billable-rate tracking on Starter is worth the modest cost if you bill by the hour.
3. Harvest — Best for Invoicing
Harvest is the pick if you want time tracking and professional invoicing genuinely combined in one tool. You track your hours, then turn them straight into invoices your clients can pay online via Stripe or PayPal.
Free plan: Limited to 1 seat and 2 projects — fine for a solo freelancer with one or two clients, but you’ll outgrow it quickly.
Paid plans (billed annually, plus usage-based fees — see below):
- Teams — $9/seat (about £7), $11 monthly — the main tier; unlimited seats, team reporting, accounting integrations
- Enterprise — $14/seat (about £11), $17.50 monthly — profitability reporting, timesheet approvals, SSO
- Enterprise Plus — custom
One important caveat: since Harvest’s 2025 acquisition by Bending Spoons, its paid plans charge usage-based fees on top of the per-seat rate — additional invoices, projects, clients, and tasks are billed based on what you use. This makes the real cost harder to predict, so check Harvest’s pricing calculator before committing.
Best for: Freelancers and small agencies who bill by the hour and want invoicing built in — provided you keep an eye on the usage fees.
Other Tools Worth a Look
The three above cover most freelancers, but depending on how you work, these are worth considering too:
- Timely — Uses AI to track your time automatically in the background rather than relying on manual timers. Powerful if you forget to hit start, but it’s pricier and takes more setup and trust. Best for people who genuinely can’t remember to track manually.
- RescueTime — Less a billing tool, more a productivity and focus tracker. It runs quietly and shows you where your attention actually goes (and how much time vanishes into email and social media). Best for freelancers trying to improve focus rather than bill clients.
(We haven’t priced these in detail here as their plans change frequently — check their current pricing directly if either appeals.)
Quick Comparison
| Tool | Free plan | Starting paid price | Best for |
|---|---|---|---|

Time Tracking and HMRC: What UK Freelancers Should Know
None of these tools are accounting software, and none connect directly to HMRC or handle Making Tax Digital. What they do is give you clean, accurate records of your billable time — which is genuinely useful for Self Assessment and for backing up your income if you’re ever queried.
For VAT returns and MTD compliance, you’ll still need dedicated accounting software such as QuickBooks, Xero, or FreeAgent. The good news is that most time trackers integrate with those tools (Clockify and Harvest both connect to QuickBooks and Xero), so you can pass your data across without re-keying it. Think of your time tracker and your accounting software as a team: one captures the work, the other handles the tax.
FAQ
What’s the best free time tracker for UK freelancers?
For a solo freelancer, both Clockify and Toggl Track offer capable free plans (each up to 5 users, with no time limit). Clockify includes unlimited projects; Toggl Track is the more polished experience. Harvest’s free plan is more limited (one user, two projects) but includes invoicing, which the other two reserve for paid plans or handle more basically.
Do these time trackers work with Making Tax Digital?
No — they’re time tracking tools, not accounting software, so they don’t connect to HMRC or handle VAT returns. However, several integrate with MTD-compatible accounting software like QuickBooks and Xero, so you can move your billable-hours data across easily. You’ll still need proper accounting software for the tax side.
Which time tracker is best if I invoice clients?
Harvest is the strongest for invoicing — it’s built in, and clients can pay online. Clockify includes basic invoicing on its Standard plan and above. Toggl Track can generate simple invoices from reports but is less of a full invoicing tool. If invoicing is central to your workflow, Harvest is worth the (carefully checked) cost; otherwise, many freelancers pair a simpler tracker with dedicated accounting software.
Are these tools priced in pounds?
No — Clockify, Toggl Track, and Harvest all price in US dollars, so your exact cost in pounds fluctuates with the exchange rate. Harvest also adds usage-based fees on top of its per-seat price. Always check the current total (and currency) at checkout before committing.
Conclusion: Which Should You Choose?
For most UK freelancers, the decision comes down to what matters most:
- Choose Clockify if budget is your priority — it has the cheapest paid plans and a still-useful free tier for up to five users.
- Choose Toggl Track if you want the most polished, frictionless experience and know you’ll only stick with a tracker if it’s genuinely pleasant to use.
- Choose Harvest if you want time tracking and professional invoicing in one tool — just check the usage-based fees so there are no surprises.
The best approach? All three have free plans or free trials. Pick the one that matches your priority, use it properly for a fortnight, and see whether it fits how you actually work. Time tracking only helps if you stick with it — so the “best” tool is ultimately the one you’ll keep using.
