Home Security FAQs: Lighting, Locks and Insurance

People tend to ask the same sensible questions about home security: does lighting really help, which locks should I trust, and will my insurance pay out if I am burgled? This page collects straightforward answers to common questions on lighting, locks, alarms, cameras and insurance. It is general information, not personal advice, and standards and policy terms change, so check the latest guidance and your own policy documents. [VERIFY: current standards]

Lighting

Does outdoor lighting really deter burglars?
Lighting reduces cover and makes it likelier that someone will notice an intruder. It is widely recommended by crime prevention advisers as a low-cost measure, though it works best alongside locks and good habits rather than on its own.

Should I use dusk-to-dawn lights or motion-activated lights?
Both have a role. Dusk-to-dawn lights at the front door and side passages provide constant visibility, and many modern LEDs are cheap to run. Motion-activated lights suit the back garden or places where you do not want constant light, as sudden illumination can alert you and startle an intruder. Position them where they cannot be easily reached or covered, and avoid shining them into neighbours’ windows.

Do timer switches for indoor lights help?
They can help make a house look occupied. Set timers to vary a little and use them in rooms that are visible from outside. Smart plugs or bulbs can randomise patterns. Remember that closed curtains during the day or an overflowing doormat can tell a different story.

Locks

What type of lock should I have on my front door?
It depends on the door material. On wooden doors, a five-lever mortice deadlock that meets the relevant British Standard (often BS 3621) is commonly specified by insurers, together with a nightlatch. On uPVC and composite doors, multi-point locking systems are usual; check the cylinder is of good quality and ideally tested against snapping, bumping and drilling. Look for recognised approvals.

What is lock snapping?
It is a method of attack on some uPVC and composite door cylinders, where the cylinder is snapped to give access to the mechanism. Cylinders designed to resist snapping, often with approved security ratings, reduce this risk. If your door lock is old and unmarked, it may be worth replacing the cylinder. A locksmith can advise.

Should I lock my doors when I’m home?
Yes. Many incidents involve opportunists walking in through unlocked doors. Lock the door when in the house, particularly at night and when you are in the garden or upstairs. Keep keys accessible to you but away from the door and letterbox, in case you need to leave quickly in an emergency.

Are smart locks safe?
Smart locks can be convenient, but their security depends on the lock quality, the app, the update policy and how you manage access. Look for models with a physical key backup, strong encryption, regular updates and a sensible approach to battery warnings. Check whether your insurer accepts them. [VERIFY]

How do I secure windows?
Fit key-operated locks to accessible windows and use them. Consider laminated glass or security film for vulnerable panes and ensure that climbing aids are removed.

What should I do about lost keys?
If keys are lost or stolen along with details of where you live, change the locks promptly. For rented property, tell your landlord or agent.

Alarms and cameras

Do I need an alarm?
Not everyone does, but an alarm can add deterrence and early warning. The right choice depends on risk, budget and insurance requirements. Our guide to wired and wireless alarms compares the options.

Are fake alarm boxes effective?
A visible alarm box can deter opportunists, but a fake one provides no protection and may be spotted. If you can afford a real system, it is generally better.

Can I install CCTV or a video doorbell myself?
Yes, many are designed for DIY. But consider where the camera points; domestic cameras capturing public areas or neighbouring property can bring data protection duties. The Information Commissioner’s Office publishes guidance for domestic users. [VERIFY: current ICO guidance]

Insurance

Does home insurance require specific locks or alarms?
Many policies include security conditions for locks on external doors and accessible windows, and some, particularly for high-value contents, may require an alarm. Terms vary, so read your policy schedule and the policy wording, or ask your insurer to confirm requirements in writing. [VERIFY: your policy]

What happens if I don’t meet the conditions?
A claim could be reduced or refused if you did not comply with a condition that applies. This is why it is worth checking before a loss, not after.

Does having an alarm or better locks reduce my premium?
Some insurers may offer discounts, but it varies. Ask your insurer or broker how security measures affect your quote.

Do I need to tell my insurer when I leave the property empty?
Some policies limit cover if the property is unoccupied for a set number of days. This matters for long holidays, hospital stays or if you are moving house. Check your policy for the number of days and ask about options. [VERIFY: unoccupancy clause]

Are valuables covered?
Policies commonly have single-item limits and overall limits for contents. Items such as jewellery, art or bikes may need to be specified separately. Keep photos, receipts and serial numbers to support a claim.

What should I do if I’m burgled?
Report the crime to the police and obtain a crime reference number, contact your insurer as soon as possible, keep receipts for emergency repairs, and avoid disposing of damaged items until agreed. Take photographs of the damage.

General habits

Where should I keep a spare key?
Avoid hiding it under a mat or plant pot, which are the first places a thief checks. Leave one with a trusted neighbour or friend.

Who can I contact for local advice?
Your local police neighbourhood team often offers free crime prevention advice, and some forces have designing-out-crime officers. Use 101 for non-emergency contact and 999 in emergencies.
