This comprehensive guide is written specifically for tenants renting in London and surrounding areas. It explains what to look for, what questions to ask, and what actions you’re legally allowed to take. It also shows how a trusted local locksmith such as SMR Locksmiths Ltd. can help you secure your new home properly before problems arise.
External door locks are the single most important security feature in any rental property. They are also the first thing insurers, landlords, and burglars assess. As a tenant, you should never assume that existing locks are adequate simply because the property is occupied or recently refurbished.
Start by checking every external door, including front doors, back doors, side entrances, and doors leading from garages into the home. Each of these should have a robust locking solution that offers real resistance to forced entry.
In most UK rental properties, this means:
British Standard locks should always be confirmed during essential tenant security checks, as insurers often make them a condition of cover. Without compliant locks, burglary claims can be delayed, reduced, or even rejected altogether.
It’s also worth checking for visible signs of wear, previous forced entry, or poor-quality repairs. Scratches around the lock, misaligned strike plates, or stiff key operation can all indicate underlying problems.
If you’re unsure whether your locks meet current standards, SMR Locksmiths Ltd. can carry out a professional inspection and advise whether a simple upgrade or full replacement is required.
One of the most common – and least discussed – security risks for tenants is poor key control. In many rental properties, keys are copied repeatedly over the years, often without accurate records being kept.
Previous tenants, contractors, cleaners, agents, or even neighbours may still have working keys. This creates a serious security concern, even if there is no immediate sign of misuse.
Before moving in, clarify:
From a practical and safety perspective, changing or rekeying the locks at the start of a tenancy is one of the most effective security measures available. Rekeying allows the internal pins of the lock to be changed so that old keys no longer work, while retaining the existing hardware.
For tenants who value convenience, locksmiths can also install keyed-alike systems, allowing one key to operate multiple doors. This reduces the need to carry several keys while still maintaining high security.
SMR Locksmiths Ltd. regularly assists tenants with secure rekeying and controlled key systems, ensuring that only authorised occupants have access.
While doors attract the most attention, windows are frequently used by opportunistic burglars – especially when they are poorly secured or left slightly open for ventilation.
Ground-floor flats, basement apartments, and properties with rear gardens are particularly vulnerable. However, even upper-floor windows can present a risk if accessible from flat roofs, extensions, or drainpipes.
As part of your essential tenant security checks, inspect:
Older properties often have sash or casement windows with outdated locking mechanisms. These may still be serviceable but often benefit from discreet upgrades that significantly improve resistance to forced entry.
A professional locksmith can recommend window security solutions that do not damage frames or violate tenancy agreements, making them ideal for renters.
Burglars rarely choose the most visible or well-protected entry point. Instead, they look for doors and access points that are hidden from view or less frequently used.
As a tenant, you should carefully inspect:
Patio doors should be fitted with anti-lift devices and secure locking systems. Communal doors should close and lock automatically without being wedged open or left unsecured.
While carrying out essential tenant security checks, any signs of faulty doors, broken locks, or unsecured communal entry systems should be addressed before moving in. A locksmith assessment can provide clear, written recommendations to help landlords or managing agents take action.
Many tenants avoid making security improvements because they are unsure of their legal rights. In most cases, tenants in England and Wales are allowed to change locks, provided certain conditions are met.
Generally, you may change locks if:
Some tenancy agreements include specific clauses about alterations, so always read the contract carefully. In practice, many landlords welcome professional lock upgrades, particularly when they improve security and reduce future risk.
A qualified locksmith such as SMR Locksmiths Ltd. can install non-destructive, reversible security upgrades that protect both your safety and your deposit.
Security is not only about preventing crime – it also affects your legal and financial position if something goes wrong. Most tenant contents insurance policies include strict requirements regarding locks and general property security.
If a burglary occurs and insurers determine that:
Your claim may be reduced or declined altogether.
Before moving in, confirm your insurer’s requirements and ensure that the property meets them. Keeping receipts and documentation for any security upgrades is also advisable.
SMR Locksmiths Ltd. regularly works with tenants and landlords to ensure properties meet insurer expectations from the outset.
Before signing the agreement or collecting keys, confirm that:
If any of these checks raise concerns, arrange a professional inspection before moving day rather than after an incident occurs.
Moving into a rental property should feel exciting, not uncertain. By carrying out essential tenant security checks, you can be confident your new home is properly protected – and SMR Locksmiths Ltd. is here to help.
