The complete moving house document checklist (the one for address changes, not boxes)

There are two types of moving checklists. The first type tells you to start packing six weeks early, label boxes by room, and defrost the fridge before the removals van arrives. That type is useful. This post is the other type — the one about what happens to your documents and official records when your address changes, and what goes wrong if you ignore it.

Most of it goes wrong quietly. Not a dramatic crisis — just a letter that doesn't arrive, a card that gets blocked, an insurance policy that has the wrong address on it when you need to make a claim. The problems surface weeks and months after moving day, when the connection back to the address change is easy to miss.

Why address changes matter more than people think

Your address appears on: tax records, bank accounts, vehicle registration, driving licence, all your insurance policies, voter registration, pension and investment accounts, your GP registration, subscriptions and delivery services, and any professional licences or memberships.

An address that's wrong on your car insurance policy can affect your premium — and in some cases, void a claim if the insurer can argue the policy was issued on the basis of incorrect information. An address that's wrong with your tax authority means correspondence goes to the previous occupant. A bank that doesn't know you've moved can flag transactions, block cards, or send statements to a stranger.

The order to do it in

Start with the addresses that have legal or financial consequences if they're wrong:

1. Tax authority (HMRC in the UK, IRS in the US, IRAS in Singapore) — your tax code, refund correspondence, and any official notices go here. Update it online; most tax authorities have a straightforward address change form.
2. Banks and credit cards — update every account. Don't assume they share information with each other, even at the same bank group.
3. Vehicle licensing authority — DVLA in the UK, DMV in the US. Legally required in most countries within a specific window after moving. The fine for not updating it is typically small but avoidable.
4. All insurance policies: home, car, life, health — your address affects your risk profile and premium. Notify each insurer separately; they don't cross-reference.
5. Electoral register / voter registration — easy to forget, meaningful. Register at the new address promptly.
6. GP and NHS registration — register with a local practice at the new address. If you're moving out of the existing GP's catchment area, you may need to re-register rather than just update. Do this early; waiting lists for new patient registrations exist in some areas.

Then the lower-urgency but still important ones:

7. Pension providers and investment platforms
8. Subscriptions: Amazon, Apple, streaming services, any regular deliveries
9. Professional memberships and licensing bodies
10. Employer payroll and emergency contact records
11. Schools and childcare providers
12. Dentist, optician, specialist consultants

The deposit protection issue

This isn't an address change topic, but it's the moving document mistake people make most often and it's worth including here.

At the end of a rental, photograph every room, every wall, every fixture — timestamped photos from your phone camera, taken on the day you return the keys. Send them to the landlord in writing on that same day, by email. Keep a copy of that email.

This is the document trail that protects your deposit in a dispute. Without it, your word against the landlord's is an even contest at best. With a timestamped photographic record and a written submission, the burden of proof shifts. Deposit disputes that look complicated are often resolved quickly once one side produces a clear photo record and the other side can't.

Documents to update vs documents that just show the old address

Your passport shows your address at time of issuance — or in many countries, no address at all. It doesn't need updating when you move. It's valid until the expiry date regardless of where you live.

Old bank statements, payslips, utility bills, and tax returns with your old address are historical records. They were correct at the time. You don't need to "fix" them — they simply reflect where you lived then. The only things that need updating are live, active records where an incorrect address would cause a problem today.

The practical question to ask for each item: if I needed to use this tomorrow, would the wrong address cause a problem? If yes, update it. If no, leave it.

The forwarding address gap

Royal Mail redirection (or its equivalent in other countries) is useful but not a substitute for updating your address. Redirection typically runs for 3 to 12 months and catches most physical mail. It doesn't catch emails, doesn't catch anything addressed to "the occupant," and ends eventually.

Use redirection as a safety net while you work through the full address update list — not as the plan. If you only set up redirection and do nothing else, you'll find out what fell through the gap when it's too late to matter.
