What it actually costs to start: a first-three-months budget

Rules and figures checked: 2026-07-24. Funding, tenancy and tax rules move — verify before relying on them.

Degree apprenticeships get sold on one sentence: earn while you learn. It's true, and it's half the reason I picked this route. What the sentence hides is the order of events. The spending starts in August. The earning starts, if you're lucky, at the end of September. Nobody at the assessment centre, in the offer letter or at any parents' evening tells you the number you actually need in the bank before your first payslip lands.

So here it is up front: if you're moving to a new city for an apprenticeship, it's somewhere between £1,500 and £2,500. This article is the working.

I'll use an illustrative example throughout rather than my own bank statements: a £120-a-week room in a shared house in a mid-size English city, and a £22,000 starting salary. Both are deliberately ordinary for 2026. SpareRoom's rental index puts the UK average room at £761 a month (usually with bills included), but London drags that up; in cities like Birmingham and Leeds a decent room in a shared house sits closer to £550 to £650, and £120 a week is £520 a month. A £22,000 salary is the unglamorous bottom of typical Level 6 starting pay, not the Google end. Your numbers will differ. The shape of the problem won't.

One scope note: I'm assuming you've already found the house and the people. If you haven't, start with finding housemates before day one and viewing rentals in a new city, then come back.

The upfront wall

Renting a room involves three payments before anyone hands you a key, and the law caps all three.

First, a holding deposit of at most one week's rent, so £120 in our example. You pay it to take the room off the market while referencing happens. When you sign, it either comes back or, more usually, counts towards your first payment. It's not extra money, but you need it weeks before everything else.

Second, a security deposit of at most five weeks' rent, which on £120 a week is £600. The cap comes from the Tenant Fees Act 2019 and applies to any tenancy where the annual rent is under £50,000, which is all of us.

Third, your first month's rent in advance: £520.

So the wall is about £1,120 in one go, with the holding deposit folded in. One thing changed recently, and in your favour. Landlords used to get around a teenager's non-existent credit history by asking for six months' rent upfront. Since 1 May 2026, under the Renters' Rights Act, they can't require more than one month's rent in advance on a new tenancy. The flip side is that guarantors now do the heavy lifting instead. What that means, and everything else about signing a tenancy before you've ever had a payslip, is in renting your first house at 17 or 18.

Getting there, and getting your stuff there

This is the spending everyone forgets to count because it happens in dribs and drabs.

Viewings first. If you're moving 150 miles, as I did, you should still view in person, which means return train tickets or a parent driving you, probably more than once. Budget £50 to £150 across a couple of trips, more if you're booking trains last minute in August, which you will be.

Then the move itself. The cheap version is one carload: a parent drives you up, you buy them lunch, the real cost is fuel both ways. The expensive version involves hiring a van. Either way, put £50 to £200 aside. I've written about the move properly in moving out at 18 for an apprenticeship; the short version is that you own less than you think, and that's a good thing.

Furnishing a room without setting fire to £400

Most shared-house rooms come furnished: bed, mattress, wardrobe, usually a desk. What's missing is everything that touches you. Bedding (mattress protector, duvet, pillows, two sets of sheets, because laundry day exists), towels, hangers, a lamp, an extension lead, a laundry bag. Plus your slice of the kitchen: a pan, a decent knife, a chopping board, some plates and cutlery if the house is short.

Go secondhand first, in this order: whatever the house's previous tenants left behind, Facebook Marketplace, charity shops (the ones near student areas restock beautifully in September), then supermarket basics ranges for anything that touches food or skin, which you'll want new anyway.

Done with discipline, this is £150. Done in one panicked IKEA trip, it's £400. The £700 "uni essentials haul" videos are for people funding it with a maintenance loan. You are not that person; you're funding it with your own summer.

The gap before the first payslip

Here's the mechanism that actually catches people. You start in early September. Payroll runs monthly, in arrears, with a cutoff date, and if you start after the cutoff your first payslip might not arrive until the end of October. Four to six weeks between day one and pay one is completely normal. Find out your exact first pay date before you move; it's in your contract or one email to HR away.

During that gap you're feeding yourself, getting to work, paying your phone bill and going to the pub with housemates you met a fortnight ago. Saying no to that pub trip is bad strategy, by the way. Budget £300 to £500 of pure living money for the gap.

And remember the deposit doesn't come back when the pain stops. It sits in a government-approved deposit protection scheme until you eventually move out. It's your money on a very long delay. Mentally, write it off for now.

The honest total

On our worked example:

That's £1,700 to £2,400 before you have earned a penny. A cheaper room or a shorter move pulls it under £1,500; a pricier city pushes it past £2,500. Nobody printed that number on the apprenticeship poster, which is exactly why I'm printing it here.

Month one: everything bleeds

Your first month in the house is a slow puncture of small costs. Bin bags. Loo roll. Cleaning spray. A bathmat. A plunger, eventually, and you'll be glad you didn't wait. None of it costs more than a fiver; collectively it's £60 to £80 of stuff that no budget template has a line for.

The food shop has its own learning curve. Your first few shops run heavy because you're buying an entire cupboard from zero: oil, salt, spices, stock cubes, all the things that were just ambiently present at home. You'll also cook badly for one person and throw food away. Expect the first month's food bill to run maybe half as much again over what it settles at. That's not failure, it's tuition.

Month two: the machine starts

Somewhere in here your first full pay cycle lands. On £22,000, take-home is roughly £1,610 a month in 2026/27 after income tax and National Insurance, before pension contributions; auto-enrolment takes roughly another £40. Call it a bit over £1,550 hitting your account.

Utilities settle in month two. If your rent is bills-inclusive, which a lot of room lets are, you skip this entirely. If not, a four-person house splitting energy, water and broadband works out around £60 to £90 each per month at current prices, with energy the big variable; the Ofgem price cap caps unit rates, not your total bill, and a house of four adults uses more than the "typical household" the headlines quote.

Council tax deserves one paragraph of your attention. If the house is on one joint tenancy, the bill lands on you and your housemates, and no, apprentices don't get the student exemption. There is an apprentice rule — a council-tax "disregard" that can cut the bill — but it only applies if you earn £195 a week or less, which on a real salary you don't. If you each signed individual room contracts, the landlord usually pays it instead. Find out which setup you're in before month two, not after the letter arrives.

Month three: your real budget appears

By month three the noise dies down and a baseline emerges. On our example, the big four look like this:

That's £710 to £930 a month of fixed reality, leaving roughly £600 to £850 of genuinely free money. Now do the one thing that separates people who are fine from people who are permanently surprised: open your banking app, look at three months of actual statements, and write your version of those four numbers down. That page is your real budget. It's better than any template because it's made of your own behaviour, and every financial decision you make for the next few years builds on it.

Where the money comes from at 17 or 18

Three sources, in order of dignity.

A summer job. You finish A-levels in June and most apprenticeships start in September. Those ten weeks are the highest-leverage earning window of your life so far, because every pound goes straight at the wall. Working that summer was the single most useful financial decision I made that year, and it wasn't close.

A parental bridge. If your family can help, frame it as a loan with a payback month, not a vague gift. "£800, and I'll pay it back by the end of November" keeps their help affordable, keeps your pride intact, and gives everyone a finish line. The alternative, an open-ended subsidy nobody discusses, quietly poisons more than budgets.

Your employer. Some employers pay a relocation allowance or starting bonus to apprentices moving for the role, and some will advance part of your first month's pay if you ask. Not all, and they rarely advertise it. Ask early careers or HR after you've signed. The worst case is a polite no, and a polite no costs nothing.

Two things not to do

Don't fund the wall with an overdraft. The famous interest-free student overdrafts are for students; you're an employee, and a standard arranged overdraft typically charges interest at rates that make credit cards look reasonable — check the current rate before you go anywhere near one. An overdraft that opens month one has a way of still being there in year two.

Don't fund it with buy-now-pay-later either. Splitting a £300 setup shop into three instalments means months two and three are paying for month one, at exactly the moment rent, bills and council tax start landing in full. And missed BNPL payments can show up on your credit file, which you will care about sooner than you think. If you can't buy the duvet outright, buy a cheaper duvet.

The bit that makes it bearable

Read back through this and it sounds brutal: two thousand pounds, more or less, before your first payslip, extracted from a teenager. But notice where all the costs sit. They're front-loaded. The deposit is paid once. The room is furnished once. The food shop learning curve is climbed once. From month three onwards, the machine just runs.

By Christmas of first year you'll have three or four payslips behind you, a rent history, the start of a savings balance and a deposit quietly waiting to come back to you one day. You will, in all likelihood, be the only eighteen-year-old you know with all four. What to do with that leftover £600-odd a month, Lifetime ISAs and all, is coming later in this money cluster. And if you're still weighing up whether this whole trade beats three years of maintenance loans, the full comparison is here: degree apprenticeship vs university.
