Moving house affects 30+ organisations that need to know your new address. Some are legal duties (DVLA, electoral roll, microchip database). Some you'll regret missing (insurance void cover, prescription delivery to old house, missed jury duty letter). And one (Royal Mail Redirect) catches everyone you forget. This is the complete UK change-of-address checklist for 2026, in the order that actually saves you time, with Cornwall-specific notes for things like South West Water and council tax handover.

Royal Mail Redirect: the safety net

Set up first. £36 for 3 months, £53 for 6 months, £76 for 12 months (2025 prices, second-class delivery for redirected mail from June 2025). Online at royalmail.com — needs to be set up at least 5 working days before the move. Add £8.50-£11 per extra person if multiple adults are moving from the same address.

This isn't a substitute for updating organisations directly — it just catches what you forgot. Concessionary rates of £22.50 available if you're on Universal Credit or Pension Credit.

Legal duties — these aren't optional

1. DVLA (vehicle and driving licence)

  • Update your driving licence address online at gov.uk/change-address-driving-licence — free, immediate
  • Update vehicle log book V5C separately at gov.uk/sold-bought-vehicle — free
  • Failure to update can result in a £1,000 fine
  • If you have a personalised registration, update it too

2. HMRC (PAYE, self-assessment, child benefit)

  • Update via gov.uk/tell-hmrc-change-of-details — free, online
  • Covers Income Tax, National Insurance, Child Benefit, Tax Credits, Marriage Allowance
  • Self-assessment filers should update separately via the SA account portal

3. Electoral roll

  • Register at the new address via gov.uk/register-to-vote — takes 5 minutes
  • You're added at the new address; the old council removes you on confirmation
  • Cornwall residents register through Cornwall Council electoral services
  • Voter ID rules apply at elections — make sure your registered name and address match your photo ID

4. NHS / GP registration

  • Find your new GP via nhs.uk postcode search
  • Register in person at the new surgery using form GMS1, with photo ID and proof of new address
  • Registration takes 2-3 weeks to complete
  • If you take regular prescriptions, ask your old GP for a month's supply before moving and ask the new GP to repeat-prescribe
  • Cornwall has GP capacity pressure in some areas (West Cornwall, Lizard) — don't delay

5. Pet microchip database

  • Legal duty under Microchipping of Dogs Regulations 2015 (and 2024 cat regulations)
  • Update via your registered database (PETtrac, Petlog, Animaltrac, Identibase or others)
  • Failure can result in a £500 fine
  • Usually free to update

Banking and financial

6. Bank current account(s)

  • Online in under 10 minutes per bank
  • Update on each bank app — many have one-click address change
  • Cards and statements re-issued to the new address within 7-10 days
  • Tell each bank separately — they don't share addresses

7. Savings, ISAs, premium bonds

  • National Savings & Investments (NS&I) — update online
  • Each savings provider has their own form
  • Premium Bonds prizes go to the address on file — update or miss the £1m

8. Credit cards

  • Each issuer separately
  • Update before any travel that might trigger fraud alerts

9. Mortgage

  • Standard mortgages: update the existing lender if porting, set up new if not
  • Buy-to-let or second-home mortgages need disclosure of changed status
  • If your new property is your main residence and the old was your only home, no change of category needed
  • See our 2026 mortgage guide for porting specifics

10. Pension(s)

  • Workplace pension via current employer's HR/payroll team
  • Personal pensions (SIPP, stakeholder) — update each provider
  • State pension via gov.uk (or DWP for under-state-pension-age changes)
  • Lifetime ISA / Help to Buy ISA — update provider

11. Investment platforms

  • Hargreaves Lansdown, AJ Bell, Vanguard, Interactive Investor, Fidelity etc.
  • Each has its own update form/process
  • Capital gains tax records use the registered address — keep it current

Insurance

12. Home insurance

  • Notify the old policy of move date — most pro-rata refund the unused premium
  • Start new policy from completion date — get 3 quotes (postcode affects premium)
  • Cornwall coastal postcodes sometimes attract flood and storm-damage premiums; inland less so
  • Listed buildings need specialist cover (NFU Mutual, Historic House Association schemes)

13. Car insurance

  • Notify the insurer immediately of address change
  • Premiums vary by postcode — some Cornwall postcodes are lower than urban equivalents
  • If you store a vehicle differently (garage vs street vs driveway) at the new property, update that too

14. Life insurance

  • Address-only update; no premium change
  • Critical illness and income protection same

15. Pet insurance

  • Address update required
  • Most UK pet insurers don't change premium by postcode but they need the address on file

16. Gadget / phone insurance

  • If covered separately from home insurance

17. Travel insurance

  • Annual multi-trip policies need address update

Utilities and council

18. Energy supplier(s)

  • Notify current supplier 2 weeks before with move date
  • Take final meter readings on move day (electricity, gas if applicable) — photograph with date visible
  • At new property, 28 days to set up account with whichever supplier serves it; default rates start the moment you take possession
  • You don't need to switch immediately — compare and switch later if rates are uncompetitive

19. Water supplier

  • Cornwall: South West Water serves nearly all of Cornwall (and most of Devon, Somerset, Dorset)
  • Set up online with your new postcode at southwestwater.co.uk
  • Take final meter reading at old property if metered
  • Some rural Cornwall properties are on private water supplies (boreholes, springs) — different rules; the seller should disclose

20. Broadband and landline

  • Most providers transfer service to the new address with 14 days' notice
  • Cornwall full-fibre coverage is good in towns (Truro, Penzance, Falmouth, Newquay) but variable in rural areas — check Openreach availability before assuming transfer
  • Some providers waive cancellation fees if they can't service the new postcode
  • Starlink as backup for rural notspots — around £75/month plus kit

21. Mobile phone

  • Address update only (number stays with you)
  • Update via the network's app or web account
  • Cornwall mobile coverage varies widely by postcode — check before relying on it

22. TV licence

  • Update at tvlicensing.co.uk — free, online
  • If you don't have a TV but have one at the new property, register
  • Failure to have a licence when needed can result in a £1,000 fine

23. Council tax

  • Notify old council of move-out date
  • Notify new council of move-in date
  • Both processes are online in 2026 — Cornwall Council, Plymouth City Council, Devon County Council all accept online change-of-address forms
  • Old council issues final bill within 2-4 weeks; new council sets up direct debit
  • If moving to a second home in Cornwall, the 100% premium applies (from April 2025) — this won't affect your direct debit setup but will affect the total bill

Subscriptions and deliveries

24. Amazon Prime, eBay, etc.

  • Update default delivery address — easy to forget after a few weeks of habit
  • Subscribe & Save items will keep going to old address until updated

25. Streaming services

  • Netflix, Disney+, Amazon Prime Video, NOW, Apple TV, Spotify — billing address only

26. Food and household deliveries

  • Tesco, Sainsbury's, Asda, Ocado, Riverford, Hello Fresh, Gousto — each separately
  • Milk delivery (still common in some Cornwall areas)
  • Prescription home delivery — Boots, Pharmacy2U, others

27. Magazine and newspaper subscriptions

  • Each separately. Print subscriptions need physical address update.

Professional and personal

28. Employer / HR

  • HR needs address for payroll and HMRC reporting
  • P60 and P45 documents go to the registered address
  • If you have a company car, the HR-provided fleet manager may need to update insurance too

29. Vet

  • Register with new vet (most accept new clients walk-in)
  • Old vet emails records to new vet on request
  • See moving with pets for the full process

30. Dentist

  • NHS dentist via nhs.uk postcode search — limited capacity in Cornwall (West Cornwall particularly stretched)
  • Private dentist re-registration straightforward but ask for records transfer

31. Optician

  • Specsavers, Vision Express transfer records on request
  • Independent opticians similar but call ahead

32. Schools and childcare

  • Apply via new council admissions portal — Cornwall Council, Plymouth City Council, Devon County Council each have separate processes
  • In-year admissions process within 15-20 school days
  • Don't withdraw the child from current school until new place confirmed in writing
  • Childcare provider, childminder, after-school club — each notified separately

33. Family and friends

  • Group text or email with the new address
  • Christmas card list update for the annual senders

34. Social media bios

  • Update if location is shown publicly (LinkedIn, Instagram, X)
  • Match what's on professional profiles for consistency

35. Annual renewals to check

  • Gym membership
  • Parking permits
  • National Trust, English Heritage, RSPB memberships
  • Warranties on appliances, electronics, garden equipment
  • Solicitor on file (for any will or LPA already filed)
  • Accountant (especially if self-employed)

Cornwall-specific items

South West Water

Set up online at southwestwater.co.uk with new postcode. Cornwall residents pay among the highest water bills in the UK (around £540/year average), so don't forget. Some rural Cornish properties have private water supplies (springs, boreholes) — different rules; the seller should disclose.

Cornwall Council services

  • Council tax handover via Cornwall Council online form
  • Garden waste subscription (annual fee, opt-in)
  • Bulky waste collection (paid service for individual items)
  • Library card (free, in-person at any Cornwall library)
  • Recycling centre access — Cornwall residents have free access for domestic loads at HWRCs

Cornish-specific deliveries to consider

  • Oil delivery (Cornwall has many off-mains-gas properties — heating oil is delivered, often on annual or 6-monthly schedule)
  • Logs delivery (wood-burner culture, common rural Cornwall)
  • Bottled gas (LPG) for off-mains properties
  • Septic tank emptying contracts (off-mains drainage common) — see septictankcornwall.co.uk for context

The order I'd actually do this in

If you're starting from scratch with two weeks before the move, the most efficient sequence:

  1. Today: Royal Mail Redirect (catches everything you forget)
  2. This week: DVLA, electoral roll, HMRC, GP search (all free and quick)
  3. This week: Banks, mortgage, pension, ISAs (online forms)
  4. Next week: Insurance providers (need to compare new postcode quotes)
  5. 10 days before: Utilities (need move date confirmed)
  6. 1 week before: Subscriptions, employer, vet, dentist
  7. Move day: Final meter readings, GP registration if possible
  8. Day after: Pet microchip update (you have 7 days legally; do it immediately)
  9. Week 1 at new place: Council tax confirmation, library card, garden waste subscription, any rural-specific (oil, septic, logs)

What's free vs paid

Free: DVLA, HMRC, electoral roll, GP registration, banks, insurance address changes (premium may change), utilities address changes, council tax updates, pet microchip update, NHS dentist registration.

Paid: Royal Mail Redirect (£36-£76 personal, £133-£275 business), private dentist re-registration (sometimes), specialist insurance reassessments at certain providers.

What happens if you forget

  • DVLA: £1,000 fine; can affect motoring offence correspondence
  • HMRC: Missed tax correspondence; possible penalty for unfiled returns
  • Electoral roll: Can't vote at the new address; credit score impacted (electoral roll is used in credit checks)
  • Insurance: Cover may be void at the new address until updated
  • Pet microchip: £500 fine; lost pets harder to reunite
  • TV licence: £1,000 fine if you're caught with a TV at unlicensed address
  • Council tax: Bills carry on at old property; new property accrues unpaid amounts
