Your salary divided by your contracted hours is the comfortable lie. Add the commute, the unpaid overtime, the work clothes, the lunches, and the tax, what you actually earn per real working hour is often shockingly low.
Your true hourly rate is your salary divided by the total time and money you actually invest in working, not just contracted hours. It includes commute time, unpaid overtime, work specific expenses (transport, clothing, lunches), and the tax and NI you pay on the salary. For most UK office workers, the true hourly rate is 30 to 50 percent lower than the simple headline calculation. Knowing your true rate is essential for fairly evaluating job offers, pay rises, and remote vs office trade offs.
Take your gross annual salary, subtract income tax, NI, and work related costs (commute, work clothes, work lunches, after work decompression). Then divide that net figure by the total hours you actually spend on work, including contracted hours, unpaid overtime, and commuting. For example, on £35,000, after tax (£24,800), minus £4,000 work costs (£20,800 net), divided by 2,500 actual work hours per year (1,950 contracted + 250 overtime + 300 commute), the true hourly rate is around £8.32, much lower than the headline £18.
Legally, no, UK employers do not have to pay for commute time, and it does not usually count as working hours. Practically, yes, your commute is time you give to your employer, with no productive value to you. A typical UK office commute of 1 hour each way means 10 hours per week, or about 460 hours per year. At a £20 per hour salary equivalent, that is £9,200 of "free work" you provide each year. Remote work essentially returns this time to you.
The average UK commute costs around £3,000 per year in 2025 once you include train tickets or fuel, parking, vehicle wear and tear, and lost time. London commuters often spend £4,000 to £6,000 per year on rail season tickets alone. Cities outside London average £1,500 to £2,500 per year for car commuting. Remote work or hybrid arrangements typically save £1,500 to £4,000 per year, before accounting for the time saved.
The honest answer is: usually yes, if the gap is less than 15 to 20 percent. A remote role pays less but eliminates commute time (typically 250 to 500 hours per year), commute cost (typically £2,000 to £4,000), and work specific expenses (lunches, clothing, after work spending). When you calculate the true hourly rate of both jobs, a remote role paying 15 percent less often produces a higher real hourly wage than the higher salary office role. Pension and benefits matter too, but the time and money savings are usually meaningful.
Two reasons. First, tax and NI typically take 25 to 35 percent of gross pay before you see anything. Second, work specific costs (commute, clothing, lunches, occasional Ubers, decompression spending) drain another £100 to £300 per month for most office workers. The combined effect is that the spendable salary is often 50 to 65 percent of gross pay. This is why people earning £40,000 can feel as financially stretched as people earning £25,000 with shorter commutes and lower work overhead.
