CoverMapKey takeaway: Changing external locks and re-registering or reconfiguring any existing alarm system should be near the top of your moving checklist — you have no way of knowing how many sets of keys or alarm codes exist from before you moved in.
In the first week
- Change or re-key external locks — previous owners, tenants, tradespeople or estate agents may still hold keys.
- Check for an existing alarm system — if one is fitted, get the code changed and ask the seller for installer/maintenance contact details.
- Update your address for any existing self-monitored smart alarm account, or arrange installation if you're setting one up fresh.
- Check window locks, especially ground-floor and easily accessible upper-floor windows.
Within the first month
- Decide on your security system — see our smart vs traditional comparison if you're starting from scratch.
- Tell your insurer what security measures are in place at the new address — this can affect both premium and any future claim.
- Check external lighting and consider security lights around entry points if none are fitted.
- Introduce yourself to neighbours — genuinely useful for informal "keep an eye out" coverage, particularly if you're not home during the day.
If you're transferring a monitored contract
Moving house while under contract with a monitored alarm provider usually means either transferring the existing equipment to the new address (subject to a survey) or ending the contract early, sometimes with a fee. Check your contract terms before you move, not after.
