If you're renting, your landlord may be responsible for handling some of the things discussed on this page. Check your tenancy agreement (or occupation contract in Wales) or speak with your landlord. If you're not sure, call our Helpline for further advice.



Around 70% of burglars enter through a door, so it’s important to protect your doors as a first line of defence. 

Make sure you know how to close your door properly. To fully engage the locking system on most UPVC or composite doors you must lift the handle, turn the key and then remove it. Don’t leave your keys in locks or lying around – put them in a safe place where they’re hidden, but where you can find them easily in case of an emergency.

Flimsy doors and inadequate locks are a security risk. Check the door frame to make sure it’s sturdy and not rotten, and make sure the hinges are strong enough. You can fit hinge bolts or security hinges for extra security. Glass panels on doors are vulnerable so it’s worth replacing them with laminated glass, which is harder to smash.

French doors, patio doors and conservatories need to be as secure as other external doors. Install additional locks and security blocks to stop lifting or forced entry. If you’re buying new patio doors, ask for the sliding section to be on the inside and for anti-lift blocks. It’s a good idea to have multi-locking systems or mortice security bolts with removable keys at the top and bottom of both doors.

When buying new doors, make sure they meet the PAS 24 standard – this is the minimum standard of security for doors and windows in the UK.


Roughly 30% of burglars enter through a window. Modern windows with multi-point locking systems don’t usually need extra locks but they should have locking handles, except on windows that may be used as a fire exit.

There are some simple precautions you can take to protect your other windows:

  • fit window locks – especially for windows that are easily accessible, such as on ground floors, above flat roofs or near a drainpipe
  • add adhesive window film to protect glazing from being smashed (make sure it meets the British Standard number BS EN 12600)
  • window shock alarms are relatively cheap and easy to fit. They may come with an adhesive warning sticker that can act as an additional deterrent.

When buying new windows, make sure they meet the PAS 24 standard – this is the minimum standard of security for doors and windows.

Other tips

  • A letterbox draught excluder makes it difficult for intruders to see inside your property.
  • A cage or restrictor on your letterbox can prevent anyone from reaching inside and trying latches or fishing for keys.
  • Get a security chain and use it when you’re answering the door. You don’t need to leave this on all the time if other key holders, such as carers, need to get in.
  • A peephole or viewer can help you identify callers – you can get these in different sizes if you have a visual impairment.
  • If you have a door security system, don’t buzz anyone in that you don’t know or if you're not expecting people.

Distraction burglary

Beware of bogus callers and always ask for ID. Door-to-door callers sometimes work in pairs – one distracts you while the other carries out the burglary. Don’t answer the door if you don’t want to, and if you do, keep the security chain on.
