Locked out of your house in the UK — the 90-second plan before you call anyone
The four steps, in order
- 115 sec
Safety check
Anyone or any pet still inside? Any hobs left on? Are you cold, wet, alone with young children, or vulnerable? If yes to safety or welfare, that changes the priority order — see the special-cases section below. If no, breathe and go to the next 30 seconds.
- 230 sec
Try the free options first
Do you have a spare key with a neighbour, a family member, a nearby friend, or a work colleague on the way home? Is a back door, a downstairs window, a patio door, or a coal-hole unlocked? If you rent, does your landlord or letting agent hold a spare (many do)? If you have breakdown or home-emergency cover, check the policy — some include a lockout call-out you have already paid for.
- 315 sec
Verify before you call anyone
Do not call the first "emergency locksmith" that comes up. Two 15-second checks: (a) Google the trading name in quotes plus "Companies House" and confirm the number matches; (b) skim their Trustpilot / Google Business Profile for reviews with dates and photos, not just five-star bursts. If it fails these, try the next result. Full checklist: /check-a-locksmith.

Send the booking message
Do not agree to a job on the phone with no written price. Send the six-question message below by WhatsApp or SMS before the trader sets off. A written total price protects you under section 51 of the Consumer Rights Act 2015; a stall or a wave-off is your answer — try the next name.
Copy this message and send it to the locksmith before they set off
A genuine trader will answer all six of these in writing without complaint. A stall or a “we’ll sort it when we get there” reply is your answer — try the next name on your list.
Locked out overnight? The overnight-specific version of this plan lives at locked out at 3am in the UK — the safe way. First question: are you safe to wait until 8am (40-75 % cheaper)? If not, the four extra checks that flush out overnight rogue traders.
Special cases — when the priority order changes
With a baby, a young child, or a vulnerable person
Priority is warmth and shelter, not the locksmith. Ask a neighbour to take you in temporarily. If you cannot find a neighbour and it is cold or late, call your local council's emergency out-of-hours line — most UK councils have a duty officer who can arrange temporary accommodation. In England: 111 for non-emergency medical concerns, 999 if the situation is a genuine emergency for the person inside or out.
In a rental flat or house
Landlord and letting agent first. Most tenancies make the landlord responsible for the lock hardware (and often for the emergency call-out too) if the lock has failed rather than you having lost the key. Losing the key is normally the tenant's cost. Send the message anyway — many landlords have a preferred locksmith on speed-dial who is cheaper than the first Google result.
Late at night or in the small hours
Overnight premiums are legitimate (roughly +40 to +75 % on top of the trader's weekday-daytime rate — see /weekend-bank-holiday-locksmith-surcharge). What is not legitimate is the trader refusing to quote the premium in writing before setting off. If you are unsafe standing outside, dial 101 for police non-emergency — an officer can wait with you while you sort the locksmith.
When the numbers change
Genuine emergency — someone inside is at risk, a fire, medical emergency, or you feel unsafe standing outside and someone is threatening you.
Police non-emergency. An officer can wait with you while you sort the locksmith, or intervene if a rogue trader turns aggressive on your doorstep.
