The first year on your own costs more than the rent

Work out what you need in the bank before you sign anything, because it isn't one month's rent. In England, a deposit is capped at five weeks' rent under the Tenant Fees Act 2019 if the annual rent is under £50,000. Add the first month up front. Call it a little over two months' rent before you've bought a single fork.

Then there's the fork. And a mattress, a kettle, a mop, a shower curtain, bin bags, a plunger you won't need until the night you really need it. On a £850 flat that's roughly £2,000 to get through the door and another few hundred to make it liveable. If you're moving in with someone, halve the second number, not the first.

That's the part people get wrong. They budget for the rent and get ambushed by the setup.

The bills that arrive whether you're ready or not

Council tax is the one that catches everybody. It isn't included unless your contract says so in writing, and if you live alone you can claim a 25% single person discount. Most councils won't apply it for you. You have to ask, on their website, usually in about four minutes.

Set every recurring payment to leave your account the day after payday. Not the 1st, not the 15th. The day after money lands. A missed direct debit can cost you a fee from the company and a mark on your credit file, and untangling that takes three phone calls and a lot of hold music.

Keep a single list of what leaves your account every month and what date it goes. Paper is fine. Mine lived on the fridge for a year: rent, council tax, energy, water, phone, contents insurance, gym. Seven lines. Once it's written down you can see, instantly, how much of your pay is already spoken for before you've done anything enjoyable with it.

Contents insurance is the one people skip. It's usually a few pounds a month and it covers the laptop you need for work. Skip the extended warranty on the toaster instead.

Your salary is not what turns up

The first payslip is a shock, and it should be. Tax, National Insurance, probably a pension contribution, possibly a student loan repayment. Look at the tax code on that payslip. If it ends in W1, M1 or X, you're on an emergency code and you may be paying too much. Payroll can tell you what they've been sent. HMRC can fix it. Neither will notice on their own.

While you're there, look at the pension line. If your employer matches contributions above the minimum and you're not taking the match, you're turning down money you've already earned. If you don't understand the options, ask your payroll team what the scheme is, then talk to a regulated financial adviser before you change anything. Don't take pension decisions from a mate in the pub.

Spend on the mattress, not the sofa

A secondhand sofa off a local listing for £40 is one of the great bargains of early adulthood. A secondhand mattress is not. You'll spend a third of the year on it and it's the single item that decides whether your first year feels manageable or grim.

Same logic everywhere else. Buy the cheap thing where failure is annoying, buy the good thing where failure ruins your week. A £12 kettle is fine. A £12 pan will warp, stick, and turn every meal into a scrubbing job until you give up and start ordering food you can't afford.

One decent knife. One heavy-bottomed frying pan. One saucepan with a lid. That's a functioning kitchen. Everything else is accumulation.

Week six

The first month is great. You've got your own door, your own hours, nobody asking where you've been. Then somewhere around week six it goes quiet on a Sunday evening, everyone you'd normally text is busy, and you realise you haven't had a proper conversation since Thursday.

This is the bit nobody tells you, and it isn't a character flaw. School and home gave you people by default. You walked past them. Now you have to build the same thing on purpose, and it feels strange to do that deliberately at first.

So put two fixed things in your week that involve other humans and don't depend on anyone remembering to invite you. A five-a-side team. A church with a Sunday evening service and people your age who go for food afterwards. A climbing gym where you see the same faces. A volunteering slot. The specific thing matters less than the fact that it recurs and someone notices if you're not there.

Two anchors. That's the whole trick.

Friendship now runs on a calendar

Your school friends will scatter, and the ones you keep will be the ones somebody organised. The group chat is not friendship. It's a notification.

Be the one who organises. Pick a date six weeks out, name a place, and send it before anyone's diary fills. Reunions that depend on everyone spontaneously being free never happen once people have shifts and commutes. And call, don't just text. Twenty minutes on the phone while you're washing up does more than four hundred messages.

You'll lose some of them anyway. That's not a failure of effort, it's just what happens when lives stop overlapping. Work on the four who'd drive two hours if you asked them to.

Photograph the flat on day one

Before you unpack, walk every room with your phone and photograph everything. The scuff on the skirting board, the stain on the carpet, the dent in the fridge door, the window that doesn't quite shut. Check the date stamps are on.

Report faults to the landlord or agent in writing, by email, even if you've already told them verbally. Verbal doesn't exist in a deposit dispute. Confirm your deposit has been placed in a government-approved protection scheme, which is a legal requirement in England and Wales, and keep that confirmation. When you move out, this folder is worth several hundred pounds to you and takes ten minutes to build.

At work, be early and ask for the second task

Your first year of work is mostly a reputation-building exercise, and reputation is built from boring things. Turn up ten minutes early. Reply to emails the same day, even if the reply is "got it, will have this to you Thursday." Finish what you said you'd finish.

When you've done the thing you were given, go and ask for another one. That single habit will separate you from most people your age within about three months, and nobody will tell you it's happening. You'll just start getting asked first.

Say yes to the leaving drinks and the Friday lunch. Not for the food. Because the person who explains how the place actually works will never explain it in a meeting.

Call your parents

More than you think you need to, and before you need something. It costs you fifteen minutes and it means the conversation you'll eventually need to have about something difficult starts from a warm place instead of a cold one.

If I could change one thing about my own first year, I'd have kept a separate account with three hundred quid in it and refused to touch it. The boiler broke in February. I put it on a card and spent the next five months paying interest on a decision I made in twenty seconds.

Open the second account this week. Name it something you'd feel embarrassed raiding.
