A key safe is one of the most useful bits of kit for any landlord — especially if you manage at a distance. It lets a vetted contractor, cleaner or letting agent into the property on a code you control, without posting keys across the country or driving over for every visit. This guide explains what to look for (including the security standard your insurer may expect) and rounds up four well-reviewed key safes UK landlords rely on.

The best key safes for landlords at a glance
Trusted brand, sturdy wall-mounted body and a simple combination dial — a dependable all-rounder.
Police Preferred Specification — the standard letting agents use, and reassuring for insurance.
Police Preferred security at a friendlier price — a strong middle ground.
A low-cost 4-digit combination box for lower-risk spots or short-term contractor access.
Why landlords use a key safe
The single biggest use is access without you being there. A gas engineer can do the annual safety check, a plumber can fix a leak, or a cleaner can turn the property around between tenancies — all on a code you give for that visit and change afterwards. For a landlord managing from another town or abroad, that turns a day’s round trip into a two-minute phone call. It also helps during inspections and viewings when you use a letting agent.
Combination, Police Preferred or smart?
Standard combination
✓ Cheapest
✓ No batteries
✗ Lower attack resistance
Smart / electronic
✓ One-time codes, logs
✓ Remote management
✗ Needs power / app
For most rentals, a Police Preferred Specification combination safe is the sweet spot: it has been independently tested to resist attack, which matters for security and can keep your insurer happy. A basic combination box is fine for lower-risk, short-term contractor access; a smart electronic safe adds one-time codes and access logs if you want tighter control across a portfolio.
Fitting and using one safely
- Site it discreetly — out of obvious view, ideally not right beside the door it opens.
- Fix it properly into masonry with the supplied bolts; a safe that can be prised off is no safe.
- Use a strong, non-obvious code — not 0000 or the house number.
- Change the code after a one-off visit and at every tenancy change.
- Tell your insurer if asked — some policies have conditions about key safes.

FAQ
Are key safes secure enough?
A good one is, especially a Police Preferred Specification model that has been tested against attack. Fit it correctly, keep the code private, and change it after one-off access.
Will my insurer accept a key safe?
Many do, particularly a Police Preferred / Secured by Design model, but some policies have conditions. Check your wording and tell your insurer if asked.
Can I let a contractor in with a key safe while I’m away?
Yes — that’s the main use. Share the code for the visit, confirm access with the tenant (who is entitled to reasonable notice), and change the code afterwards.
Where should I fit a key safe?
Somewhere discreet and solid — into masonry with the supplied fixings, out of obvious sight, and ideally not immediately next to the door it opens.
