The commute you're not doing is worth somewhere between £2,000 and £4,000 a year — which means a remote job paying slightly less than an office one can still leave you better off. Almost nobody does this maths before accepting an offer, and the people who do tend to get it wrong in both directions: they forget the heating bill, and they forget the tax relief.

Price the commute you're not making

Start with the big line. If you were commuting into London from the surrounding towns, an annual season ticket runs £3,000–£5,000 depending on the line, and that's after-tax money — you'd need to earn £4,000–£7,000 more gross to cover it. Inside a big city, a monthly bus or tram pass costs £60–£80, call it £700–£900 a year. Drivers do worse than they think: a modest ten-mile-each-way commute burns £600–£900 a year in fuel at 2026 prices, before parking, tyres and the extra insurance mileage.

Then the small lines, which aren't small over 230 working days:

  • Lunch. A £4–£5 meal deal every office day is £900–£1,150 a year. Leftovers at home cost pennies over what you'd cook anyway.
  • Coffee. Two £3.50 flat whites a week is £350 a year; one a day is £800.
  • The incidentals. Work wardrobe, dry cleaning, the Friday drinks you didn't quite want. Budget £200–£400 and you won't be far out.

A full-remote job versus a five-day city-centre commute is comfortably a £2,500–£4,500 annual swing for most people. That is a pay rise no manager has to sign off.

The £6 a week from HMRC — who still qualifies

During Covid nearly everyone could claim working-from-home tax relief. The rules have tightened, and this is the bit people get wrong in 2026: you can only claim if you're required to work from home — because your employer has no office, or your contract says home-based — not because you choose to skip the commute. Voluntary hybrid doesn't count.

If you do qualify, the flat rate is £6 a week without receipts, claimed through gov.uk. That's worth £62.40 a year to a basic-rate taxpayer and £124.80 at higher rate — not life-changing, but it's a ten-minute form and it can be backdated. Alternatively your employer can simply pay you £6 a week tax-free as a homeworking allowance; some do if asked, since it costs them less than a pay rise of the same value. There's also an actual-costs method with receipts and apportioned bills, which is rarely worth the spreadsheet unless your home office genuinely eats energy.

What working from home costs you back

Honesty column. Heating a house all day in January instead of letting it sit cold costs £1–£2 a day depending on insulation and tariff — call it £100–£200 across a winter. Electricity for a laptop and monitor is trivial, a few pounds a month. Broadband you were paying for anyway. If you're on a smart tariff, running the washing machine off-peak while you work claws some of it back.

The genuine cost is winter heating, and even at the top end it's a tenth of what the commute was costing. It is what it is: a £150 bill against a £3,000 saving.

The salary catch nobody mentions in the offer letter

Remote roles are increasingly priced nationally, which means the London weighting you'd have got in an office job — often £3,000–£6,000 — quietly isn't there. That's not a scandal; it's just a number that belongs in your comparison. A £30,000 remote job against a £34,000 office job with a £3,500 season ticket and £1,000 of meal deals is close to a dead heat before you've counted a single hour of your life back.

Hybrid workers should look at flexi season tickets, sold through National Rail for people travelling two or three days a week. On some lines they beat daily tickets comfortably; on others, off-peak day returns win. Run your actual line through the calculator before renewing anything — the answer varies more than the marketing suggests.

Do the sums for your own offer

Before you accept or reject anything, spend ten minutes on this:

  • Commute cost per year, after tax (multiply the gross figure you'd need by roughly 1.3 to compare against salary)
  • Lunches and coffees at your honest, not aspirational, rate
  • Minus £150–£200 winter heating if you're home full-time
  • Plus £62.40 if you're genuinely required to work from home and claim it
  • Minus any London weighting the remote job quietly dropped

Most people find the remote job is worth £2,000–£3,000 more than its headline salary — and that's before pricing the ten hours a week you're no longer standing on a platform. Nobody puts that line on a payslip, but you'll notice it every single Monday.
