Moving to the UK involves a steep learning curve for your finances. The UK tax system, banking, credit, and pension framework are distinct from almost everywhere else in the world.
This guide covers every financial step for new arrivals — from your first week to your first year.
Week 1: Urgent Financial Foundations
1. Open a Bank Account
Without a UK bank account you can’t receive salary, pay rent, or set up Direct Debits. But traditional banks require proof of UK address — which you don’t have yet.
Fastest approach — digital banks (no UK address required):
| Provider | What you need | Waiting time |
|---|---|---|
| Monzo | Passport or EU national ID | Minutes to hours |
| Starling | Passport or national ID | Hours |
| Revolut | Passport or national ID | Hours to 1 day |
All three provide a sort code and account number immediately — a fully functional UK current account.
Once you have a UK address (1–3 months): You can then open a high-street bank account if preferred (Barclays, HSBC, Santander, etc.). HSBC Global Money and HSBC Premier are particularly useful if you already bank with HSBC internationally — they can link accounts across countries.
2. Apply for a National Insurance Number
Your NI number is essential for work, benefits, and building your State Pension record. Apply as soon as possible.
How to apply: Via GOV.UK — gov.uk/apply-national-insurance-number
Requirements:
- Right to work in UK (visa, British/Irish passport, settled status)
- Identity documents
- You may need to attend an appointment
Timeline: Processing takes 4–8 weeks typically. You can start work before receiving it — but keep chasing it, as it’s needed to ensure correct PAYE deductions.
3. Understand Your Tax Position
Are you UK tax resident?
The Statutory Residence Test (SRT) determines your formal tax residency. Most people moving to the UK full-time and working here become UK tax resident from their arrival date (or from 6 April, depending on tie circumstances).
What UK tax residency means:
- You pay UK income tax on your UK earnings
- You may pay UK tax on worldwide income if “domicile” also becomes UK
- Double taxation treaties may apply to prevent you paying tax twice in two countries
Your first tax year may be a split year — part home country, part UK. The SRT has specific split-year rules. This may be worth reviewing with a tax adviser in your first year.
First Month: Payroll and Tax Setup
4. Give Your Employer Your NI Number and Correct Starter Details
Your employer will ask you to complete a Starter Checklist (formerly P46). Answer honestly:
- Statement A: This is your first job since last 6 April — choose if you’ve not worked in the UK before
- Statement B: This is your only job and you had another since 6 April — choose if applicable
- Statement C: You have another job or pension — choose if applicable
Your answer affects your initial tax code. Without a P45 from a UK employer, you’ll likely receive a temporary emergency code (1257L W1/M1). This corrects once HMRC processes your record.
5. Register on the Electoral Roll (Once You Have a Right to Vote)
If you’re a British citizen, Irish citizen, or qualifying Commonwealth citizen with indefinite leave to remain, you can register to vote — and should do so for credit purposes:
- Register at gov.uk/register-to-vote
- Being on the Electoral Roll is one of the most impactful steps for building UK credit history
Non-EU/EEA migrants without settled status generally cannot register to vote.
Building UK Credit History from Zero
Credit in the UK is entirely separate from your home country. You start with no credit file.
Step-by-Step to Build UK Credit
Essential first steps (do immediately):
- Open a UK bank account (challenger banks work; aim to be credit-searched by the bank)
- Register on the Electoral Roll (if eligible)
- Ensure your name is on utility bills in your home
Build active credit: 4. Apply for a credit-building card — designed for people with thin or no credit history:
| Card | Monthly fee | Notes |
|---|---|---|
| Capital One Classic | £0 | 34.9% APR — only use for small purchases, repay in full |
| Aqua Classic | £0 | Credit-builder specifically for new-to-credit |
| Barclaycard Initial | £0 | Barclays entry card for building history |
| 5. Use the card for small purchases only — one tank of fuel, one grocery run | ||
| 6. Repay the full balance before the statement date each month — never pay interest |
Avoid:
- Multiple credit applications in quick succession — each leaves a search mark
- Store cards with high APRs
- Payday loans — these damage applications to mortgage lenders later
Timeline: A reasonable credit profile typically takes 6–12 months of consistent positive behaviour.
Understanding UK Tax
Income Tax
UK Income Tax is charged at three rates (2026/27):
| Band | Taxable income | Rate |
|---|---|---|
| Personal Allowance | Up to £12,570 | 0% |
| Basic rate | £12,571–£50,270 | 20% |
| Higher rate | £50,271–£125,140 | 40% |
| Additional rate | Over £125,140 | 45% |
Tax is deducted automatically from employment income via PAYE. You don’t need to file a tax return unless you have additional income (freelance, rental, overseas) or earn over £100,000.
National Insurance
Employee NI Contributions (2026/27):
- 8% on earnings between £12,570 and £50,270
- 2% on earnings above £50,270
NI contributions build entitlement to the State Pension and contributory benefits. To receive the full new State Pension you need 35 qualifying NI years. Each year you work in the UK adds to your record.
Overseas Income
If you receive income from your home country while living in the UK:
- It may be taxable in the UK depending on your domicile and residence status
- A double taxation agreement (DTA) between the UK and your home country may eliminate double taxation
- You may need to declare this on a UK Self Assessment return
See our Double Taxation Treaties Guide for country-specific guidance.
ISAs: UK Tax-Free Savings
Once you’re UK tax resident, you can open an ISA — the UK’s tax-free savings wrapper:
- Cash ISA: Up to £20,000/year; interest is tax-free
- Stocks and Shares ISA: Up to £20,000/year; gains and income are tax-free
- Lifetime ISA: Up to £4,000/year for first-home buyers or retirement (must be under 40); 25% government bonus
ISA accounts are UK resident only. You cannot contribute to an ISA once you leave the UK (though you can keep existing ISAs tax-free during absence).
Workplace Pensions
If you’re employed and earning over £10,000/year aged 22–66, your employer must auto-enrol you into a workplace pension:
- Minimum contributions: 5% from you + 3% from employer = 8% minimum
- Provider: Your employer chooses the pension provider (NEST, Aviva, Legal & General, etc.)
- Don’t opt out: You lose the employer contribution — that’s free money
Pension portability: If you ever leave the UK, you have options for your UK pension (drawdown from abroad, QROPS transfer to an overseas scheme in some cases). See our QROPS Guide.
Finding a Home: The Rental Process
Renting is the most common first step for new arrivals. What lenders and landlords need from you:
Landlord requirements:
- ID (passport)
- Right to Rent check (UK landlords must verify your immigration status)
- Last 3 months’ bank statements
- Employment contract or offer letter
- References (employer, previous landlord)
New arrivals with no UK credit history are often required to pay a larger deposit (up to 5 weeks’ rent legally) and may face tougher referencing. A guarantor (employer or UK-based contact) can help.
Deposit protection: UK landlords must place your deposit in a government-approved Tenancy Deposit Scheme within 30 days.
