Moving out for the first time costs more than most people expect, and it tends to happen faster than they’re financially ready for. Most people plan for the rent. Far fewer plan for everything that arrives alongside it.
1. The upfront costs
Before you move in anywhere, you’ll need a significant sum of money available. This is the part most people underestimate.
Deposit
In the UK, since the Tenant Fees Act 2019, deposits are capped at five weeks’ rent for properties with annual rent under £50,000. On a £1,000/month flat, that’s around £1,154. Deposits must be held in a government-approved tenancy deposit scheme and returned at the end of the tenancy, minus any legitimate deductions for damage.
In the US, deposit rules vary by state. One to two months’ rent is common. On a $1,500/month apartment, expect $1,500–3,000 set aside for the deposit alone.
First month’s rent
Usually due at the start of the tenancy alongside the deposit. Before you’ve moved in, you’re already looking at around six weeks’ worth of rent in the UK and two to three months’ rent in the US.
Moving costs
A self-drive van for a local move in the UK typically runs £80–200 for the day. A removal company costs more — £300–1,000 for a small flat, depending on distance. In the US, a local move with movers averages around $800–2,000.
Furniture and essentials
Unless you’re moving into a furnished flat, the initial setup is a real cost. Furnishing a one-bed from scratch — bed, sofa, dining table, basic white goods if not provided — runs roughly £1,500–3,000 in the UK. Buying second-hand cuts this significantly.
The things people forget: a kettle, cleaning supplies, a hoover, kitchen basics, hangers, a laundry basket, a bin. None expensive individually. Together easily £100–200.
Total upfront picture
For a £1,000/month flat in the UK, a conservative estimate:
- Deposit (5 weeks): ~£1,154
- First month’s rent: £1,000
- Moving costs: ~£200
- Basic furniture and essentials: ~£1,500
Around £3,850 before you’ve cooked a single meal there.
2. The monthly costs
Rent
Average rents in the UK outside London for a one-bedroom flat ranged from roughly £700–1,200/month in 2024 depending on the city. In London, £1,500–2,200 is more typical. In the US, a one-bed in a mid-tier city might run $1,000–1,600/month, with major cities considerably higher. How much of your income should go on rent covers the financial benchmarks in detail.
Utilities
Gas and electricity for a one-bed flat in the UK average around £60–100/month. Broadband adds another £25–45. In the US, electricity and heating vary by climate, but $80–150/month for a small apartment is common. Water is often included in UK rent; in the US it’s frequently billed separately.
Council tax (UK)
One of the most commonly missed costs for first-time renters. Council tax is set by the local authority and charged per household. Single occupants get a 25% discount, bringing typical bills to £80–180/month depending on area and property band. Students in full-time education are exempt — once you graduate, that exemption ends.
TV Licence (UK)
£169.50 per year (2024/25), around £14/month. Required if you watch live TV or use BBC iPlayer. Many young renters no longer need one if they only use streaming services.
Contents insurance
Your landlord’s insurance covers the building. It doesn’t cover your laptop, phone, or anything else you own. Contents insurance for a first flat typically costs £5–15/month in the UK and around $15–20/month in the US. Worth having.
Food and groceries
A realistic monthly food budget for one person cooking most meals at home: £200–300/month in the UK, $250–400/month in the US depending on diet and location.
Transport
If you’ve moved somewhere with a commute, budget for it. A monthly Travelcard in London costs £205+ per month depending on zones. A US monthly transit pass ranges from around $50–130 by city.
3. The costs people forget
Home maintenance supplies. Lightbulbs, batteries, cleaning products, toilet paper, bin bags — these accumulate. Budget around £20–30/month for ongoing household supplies.
Internet setup delay. New broadband connections in the UK often take 1–2 weeks to activate. Factor in either a temporary mobile data solution or the waiting period.
Parking permits. In many UK cities, residents need a council parking permit if they have a car. Costs range from under £100 to several hundred pounds per year depending on area.
The first energy bill. Heating a cold flat from scratch and having appliances running constantly while you settle in means the first month of energy use is usually higher than your eventual average.
Furniture replacement. Things break. The sofa bought cheaply at the start will need replacing eventually. Budget for it over time rather than treating your initial setup as permanent.
4. How to budget before you commit
Work out your total monthly outgoings before you sign anything. Add up rent, council tax, all utilities, contents insurance, food, and transport. The number you reach is your real monthly cost of living in that flat. Most financial guidance suggests keeping total housing costs (rent plus bills) under 35–40% of take-home pay — though in high-cost cities this is hard to achieve.
The monthly budget guide is a useful tool for mapping this out fully before you commit.
For a UK renter, having £4,000–5,000 saved before you start viewing gives you enough for upfront costs without arriving in the flat with nothing left. In the US, $3,000–5,000 is a realistic minimum depending on the market.
Once you’re settled, start building an emergency fund specifically for the flat. A boiler breaking down or a white good failing shouldn’t become a financial crisis. How to build an emergency fund covers the strategy.
5. What first-timers get wrong
Signing for the most they can afford leaves no margin. A more modest flat that leaves £200/month breathing room is a better financial position than the nicest one you can technically manage. The nicest flat stops feeling nice when you can’t afford to do anything else.
Not reading the tenancy agreement properly is another. Early exit clauses, what’s included in rent, who’s responsible for maintenance — it’s all in there. Understanding it before signing prevents disputes later.
Assuming furnished means fully equipped. A furnished flat usually has a bed, sofa, and some basic furniture. It rarely includes kitchen essentials, cleaning supplies, or everything else needed to actually live there.
Not documenting the flat at move-in. Getting a deposit back requires leaving the flat as you found it. Check the inventory thoroughly on arrival, photograph any existing damage, and keep records. Deposit disputes are common and almost entirely avoidable with decent documentation.
Before you start viewing
The financials are worth working out before you fall in love with a flat. A place that looks perfect but leaves no financial room isn’t perfect — it’s a source of ongoing stress.
How much of your income should go on rent is worth reading alongside this for the income benchmarks. And cutting your monthly bills covers where to find savings once you’re in.
