Short-let properties such as Airbnb homes operate very differently from standard residential properties. With frequent guest turnover, self check-ins, cleaners, contractors and remote management, security risks increase significantly if the right systems are not in place.
In London especially, where short-lets are often targeted due to high property density and anonymity, hosts need a proactive security strategy – not just a set of locks on the door. This guide explains the key areas every Airbnb or short-let host should address, and why they matter.
One of the most common mistakes short-let hosts make is assuming that access automatically ends when a guest checks out. In reality, physical keys can be copied, PIN codes shared, and access details passed on without the host ever knowing.
From a security and insurance perspective, hosts must be able to demonstrate full control over who can enter the property at any given time. If a break-in occurs and there is uncertainty over access, insurers may question whether the property was adequately secured.
For hosts using traditional keys, this often means regular re-keying or lock replacement, particularly after long stays, lost keys or disputes. Modern access systems allow hosts to change access instantly, ensuring security is restored between bookings.
Keyless entry systems have become increasingly popular with London Airbnb hosts. When installed professionally, they remove many of the risks associated with physical keys while improving convenience for both hosts and guests.
These systems allow hosts to issue unique access codes, set time-limited entry and manage access remotely. However, not all smart locks are suitable for insurance or long-term security. Poor-quality devices or incorrect installation can weaken door integrity.
For short-let use, keyless systems should always retain a secure mechanical lock and meet British Standard expectations.
For properties still using keys, key control is essential. Over time, cleaners, contractors and co-hosts may retain access, increasing security risks.
Effective key control means limiting the number of keys in circulation, avoiding easily copied keys and changing locks when access is no longer required. Cheap external key safes are particularly vulnerable and are frequently targeted by burglars in London.
Most UK insurers specify exactly what type of locks must be fitted to external doors, and failing to meet these requirements can lead to rejected or reduced claims.
Insurers usually expect British Standard compliant locks designed to resist common burglary methods such as snapping, drilling and forced entry. For timber doors, this often means BS3621 mortice deadlocks or nightlatches. For uPVC and composite doors, a multipoint locking system fitted with a TS007 3-Star anti-snap euro cylinder is typically required.
A common misconception among hosts is that having a multipoint door automatically means the property is compliant. In reality, the cylinder itself must meet security standards. Low-grade cylinders are a major weak point and are frequently targeted by burglars.
Smart locks and keyless entry systems do not automatically satisfy insurance requirements. Most insurers still require a compliant mechanical lock beneath any smart system. Poor installation or consumer-grade hardware can weaken the door and potentially invalidate cover.
Professional assessment is strongly recommended, especially for older properties or converted flats. A locksmith can confirm compliance, upgrade locks where needed and provide documentation that may be required during an insurance claim.
In many burglaries, the front door is not the point of entry. Burglars often target secondary access points that receive less attention, especially in short-let properties.
Commonly overlooked entry points include rear and side doors, basement entrances, patio doors and windows accessible from flat roofs or communal areas.
Securing these areas is essential and may involve:
Short-let properties in London often feature converted layouts and shared access, making these vulnerabilities easier to exploit. Strengthening secondary entry points significantly reduces overall risk and improves insurance compliance.
A full security assessment ensures that all access points are protected to the same standard, not just the main entrance.
Security should never prevent guests from escaping safely in an emergency. Airbnb hosts must ensure that locks fitted to exit doors allow occupants to leave quickly and easily without needing to search for keys.
Locks that require key operation from the inside can be dangerous, especially for guests unfamiliar with the property. Thumb-turn cylinders and simple internal release mechanisms are strongly recommended.
This is particularly important in flats and converted buildings, where fire safety regulations are stricter. Choosing the wrong type of lock can increase risk, liability and potential legal consequences. A professional locksmith can help balance strong security with safe, compliant escape routes.
Lost phones, forgotten codes and mechanical failures are common in short-let properties. Having a trusted local locksmith available prevents cancellations, negative reviews and unnecessary stress.
Short-let Airbnb properties experience significantly more wear and tear than owner-occupied homes. Doors, locks and handles are used frequently by guests who may not be familiar with the property or its security systems.
Without regular maintenance, minor issues such as stiff locks or misaligned doors can quickly develop into complete lock failures, often resulting in emergency call-outs, cancelled bookings and negative reviews.
Routine inspections help identify early warning signs including:
Addressing these issues early is far more cost-effective than dealing with a lockout during a guest stay. Regular maintenance also ensures locks remain fully operational, which is essential for insurance compliance.
For Airbnb and short-let hosts, arranging periodic security checks with a professional locksmith helps prevent failures, reduces emergency costs and ensures guests enjoy a smooth, problem-free stay.
Keeping records of lock installations, upgrades and inspections is essential. Documentation helps protect hosts during insurance claims and demonstrates proper security management.
