The moat · what generic trackers miss

Every UK deduction.
Handled properly.

Global time trackers show you hours. Clok is the only one that models the actual mess of UK PAYE — the codes, the umbrella cuts, the loans, the CIS deductions — and shows you what actually hits your bank.

Only in Clok

Every tax code

1257L · BR · D0 · K · NT · W1

Full UK tax-code parser incl. Scottish (S) 5-band, Welsh (C), emergency codes, K codes (negative allowance). Change your code, every past period recalculates instantly.

Only in Clok

Rolled-up holiday

12.07% on every hour

Agency and umbrella workers get holiday pay per shift, not per booked day. Clok tracks the pot so you can set it aside for time off — nobody else even attempts this.

Student loans

Plans 1 / 2 / 4 / 5 + PGL

HMRC-accurate. 9% above each plan's threshold; 6% PGL on £21k+. Auto-picks the lowest-threshold plan if you have more than one — matches how PAYE actually works.

Only in Clok

CIS mode

Construction 20% / 30% + materials split

Registered subcontractors: 20% (or 30% unregistered) at source. Log materials/plant hire inline on the pay period card — HMRC exempts them, Clok shows exactly what you save.

Only in Clok

Umbrella mode

Margin + Levy + Employer NI (with brand)

Contract rate → −Umbrella margin → −Apprenticeship Levy (0.5%) → −Employer's NI (15%) → Your assignment rate. Add your umbrella's name and the payslip PDF reads like an authentic umbrella payslip.

Only in Clok

Expenses Hub

Mileage + receipts + tax integration

Self-employed only. Log business mileage (HMRC 45p/25p split), tools, training, subsistence. Snap receipts from the mobile camera. Every entry drops your "Set aside for HMRC" in real time.

Only in Clok

Appearance & accessibility

Themes for every kind of eye — colour-blind safe built in

Four themes — Dark, High contrast, Light and Colour-blind safe — plus six accent colours and three text sizes. Colour-blind safe swaps every red/green pair for blue/orange, so the pain lines stay legible without depending on red or green. Free on every tier.

Payslip export

One-tap UK payslip PDF

Every deduction on a proper A4 payslip. Tax code, NI cat, gross, IT, NI, SL+PGL, pension, rolled-up holiday, YTD figures. Reconcile against your umbrella payslip in seconds.

New · Self-employed

Every quid you save
from HMRC.

Sole traders and CIS subbies under-claim expenses to the tune of hundreds a year. Clok's Expenses Hub logs mileage at the HMRC rate (45p first 10k / 25p after), tools, materials, training, subsistence — and drops your set-aside as soon as you tap Save.

  • HMRC mileage split tracked across the tax year
  • Snap receipts from the phone camera (JPG · HEIC · PDF)
  • Category totals + Self Assessment-ready summary
  • Set aside for HMRC recalculates in real time

About the maker

MW

Martyn Wheatley

Founder · Leicestershire, UK

I built Clok because every time-tracking app I tried was made for the US market — spitting out numbers that had nothing to do with what actually lands in a UK bank account after Income Tax, National Insurance, and pension.

UK workers, agency staff, sole traders, and small teams all deserve a tool that speaks their language and shows the honest number. So I made one — solo, in the UK, with real 2026/27 tax logic baked in.

If Clok helps you or something feels wrong, I want to hear from you personally. I read and reply to every email.
