Should I Lock my Door at Night?

Locking your door at night may seem like a simple part of your nightly routine, but a shocking 42% of people in the UK leave their home unlocked at night, only locking the door if they leave the home overnight. 77% of burglars enter a property through a door, and in 10% of these cases, the door was left unlocked.

Why Locking Your Door Matters

Locking your door provides an additional layer of protection and reduces the risk of someone entering your home. Simply locking your home can make all the difference in keeping you and your family safe.

Two-thirds of break-ins occur via the front or back door, or through ground-floor windows, so a quick check of all entry points each night can go a long way towards preventing a potential burglary.

Your front door is the most common target for burglars, so security is crucial in keeping your home safe. Whilst crime rates vary across the country, no one is completely immune to opportunistic threats.

Unlocked doors are easy targets, and with 19% of burglaries taking place between 6pm and 10pm, when visibility is lower, it’s important that you take steps to reduce your risks.

 

Home Security Tips for Night-time

There are several steps you can take to enhance your home security at night, beyond simply locking your doors. These tips are especially beneficial for those living alone, those in secluded areas, or those who live in places where burglaries are common.

 

Security Systems

63% of burglaries happen to people without a basic home security system. Outdoor security cameras are one of the most effective ways to secure your home. Both wired and wireless security systems have their benefits. They are excellent deterrents and, if the worst were to happen, they provide footage for the police.

A burglar alarm is also a fantastic deterrent and can offer peace of mind when locking up for the evening.

Outdoor Security Lighting

Security lights are a great way to boost your home security. They illuminate anything moving too close to your home and remove the cover of darkness from those attempting to break in.

Door & Lock Enhancements

Your front door lock is the first line of defence against intruders, so having a high-quality, functional and secure lock is essential. It’s also a good idea to check your insurance policy for approved lock types—these often meet high security standards and help ensure your coverage remains valid.

Leaving your door unlocked overnight can allow unwanted individuals to enter your home. Consider enhancing your door’s security with features like a door chain or spyhole.

Windows & Conservatories

Secure windows can prevent another means of entry into your home. Sturdy locks are standard in most modern uPVC windows, and the stronger your windows appear, the less likely someone is to attempt entry through them.

Your conservatory or patio door security is just as important as your front door and windows. Quality installation and secure locks can help keep your home protected.

Family and Indoor Safety

Keeping your children and pets safe is essential. If you have children who sleepwalk or often wander the house late at night, it can be dangerous. They could get into drawers, climb on furniture or even open the front door if it’s left unlocked.

Indoor security cameras, child-proof windows and doors, and an alarm system are all useful for keeping an eye on young children.

Pet cameras are great for monitoring pets whilst you’re at work or away. They also add a layer of security, as they often record movement. With pet ownership increasing and cases of dog theft on the rise, pet cameras can reduce the risk of your pet being stolen. Pet locks may also be helpful for pets that get into rooms or cupboards they shouldn’t.

 

Insurance Considerations

What many people don’t realise is that not locking your doors—especially at night or when leaving the house—can actually invalidate your home insurance. A report from MoneyPages stated that almost 19% of insurance claims rejected were due to homeowners not taking reasonable care. Something as simple as locking your door could be the difference between receiving full compensation or having your claim denied.

 

Special Considerations

Internal Fire Doors

Sometimes doors should not be locked—specifically internal fire doors. Locking a fire door can pose significant safety risks. A locked bedroom door can prevent emergency services from entering rooms efficiently and may affect their ability to rescue occupants. Fire and smoke alarms will alert you to danger, but locking fire doors can be hazardous. Test batteries regularly, including those in carbon monoxide (CO) alarms. CO is invisible and odourless, making it impossible to detect without an alarm.

Bedroom Doors

There are both pros and cons to locking your bedroom door at night. It can provide additional security and privacy, but you should consider whether the benefits outweigh the risks—such as delayed escape during a fire.

Key Safety

You may be in the habit of leaving your key in the lock at night once you’ve secured your home, but this is not recommended. A burglar may be able to use it to gain entry, either via a nearby window or the letterbox. It’s best to leave them in a designated safe spot which cannot be seen from the front door or windows.

Child Bedroom Doors

Although it might seem like there are extra security benefits, it’s not recommended to lock your child’s door at night, especially if they are under 11. This is important for their safety in case of accidents or emergencies.
