What it does
Everything a locum needs. Nothing they don't.
Designed for UK locums — GPs, doctors, nurses, and pharmacists — not a generic expense tracker with a stethoscope icon on it.
Session tracking
Log sessions in seconds — site, session type, hours × rate, fee. With Pro, import directly from Lantum, LocumDeck, Locate a Locum, and iCal feeds.
Mileage & expenses
Return mileage and your estimated deduction, worked out at the right HMRC rate for each tax year (55p a mile for 2026/27). Parking, subscriptions, and other SA103S expenses tracked by quarter.
Invoices & payment tracking
Mark sessions as invoiced, awaiting payment, or paid. See outstanding amounts and chase overdue invoices with Pro.
HMRC tax export
Pro exports PDF and CSV covering gross income, mileage deductions, SA103S categories, and quarterly figures for self-assessment.
NHS pension Form A, Form B & SOLO
Track pensionable pay per session and generate Form A, Form B, and SOLO for GP locums in England, Wales, Scotland, and Northern Ireland. Export a monthly Form A pack as a merged PDF or ZIP.
Earnings analytics
Monthly and annual income charts, average hourly rate, tax-year summaries, and a Types tab with income by session type — unlock with Pro.
Why is core tracking free?
LocumBook's essential tools — session logging, invoice tracking, and mileage — are free forever. Your session data and financial figures stay on your device by default, never sold or shared. Upgrade to Pro when you need PDF exports, analytics, NHS pension forms, and cloud sync.
How it works
Up and running in five minutes
Set up your profile
Enter your name, registration number, home postcode, and invoice details once — then they are pre-filled everywhere.
Log a session
Tap +, choose the workplace and session type, enter hours — fee fills from your rate. With Pro, import shifts from Lantum, LocumDeck, or your calendar feed.
Track invoices
Mark sessions as invoiced, awaiting payment, or paid. See outstanding amounts on your dashboard.
Export for tax time
With Pro, export PDF and CSV summaries covering MTD quarters, SA103S categories, and mileage — ready for your accountant.
NHS Pension
The pension forms nobody enjoys — handled.
With Pro, LocumBook calculates your NHS pension figures from your session data and generates Form A, Form B, and SOLO for England, Wales, Scotland, and Northern Ireland.
Pensionable pay is calculated at the statutory 90% of your locum fee per NHSBSA guidance. England (PCSE), Wales (LHB), Scotland and Northern Ireland (NSS/HSC) jurisdictions supported.
