A home security checklist UK homes starts with your doors and locks, then covers windows, the garage, and everyday habits. Work through it room by room, fix the quick wins first, then upgrade any weak locks to a recognised security standard.
Most break-ins target the easiest weak point, so a simple audit finds the gaps before a burglar does. This checklist takes you through your home in the order that matters most, starting with the doors that account for most break-ins. Tackle the fast, free fixes first, then plan the upgrades that give lasting protection.
What are the quick wins first?
The quick wins are the free habits that stop opportunist burglars: lock every door and window, remove keys from the latch, keep valuables out of sight, and never leave a spare key outside. These close the gaps that many break-ins exploit before you spend anything.
Home security is the set of locks, habits, and hardware that keep intruders out. The Office for National Statistics links around 70% of burglaries to door entry, and a large share involve no forced entry at all, because a door or window was left open.
Start with these no-cost actions:
- Lock every external door and ground-floor window, even when you are at home.
- Remove keys from the door and keep them out of reach of the letterbox.
- Keep car keys, wallets, and valuables away from windows and the front door.
- Never hide a spare key outside; leave one with a trusted neighbour instead.
- Close curtains at night and make the home look occupied when you are out.
These habits cost nothing and remove the easy opportunities burglars look for first.
What should be on a room-by-room home security checklist?
A room-by-room home security checklist covers the front door, back and patio doors, windows, the garage and shed, and the garden boundary. Each area has its own weak points, and checking them in turn shows exactly where your home needs attention.
| Area | What to check |
| Front door | Anti-snap cylinder, deadlock, solid frame, viewer, letterbox guard |
| Back and patio doors | Multipoint lock working, key removed, sash jammer fitted |
| Windows | Locks fitted and used, keys stored safely, limiters on upper floors |
| Garage and shed | Strong lock or hasp, tools locked away, internal door secured |
| Garden and boundary | Gates locked, ladders stored, gravel and lighting as deterrents |
| Whole home | Working smoke alarms, a safe for valuables, lights on timers |
Going through each area in turn means nothing is missed, and it tells you which fixes are habits and which need new hardware.
Doors and locks
Doors are the priority, because they are the most common way in. Check that every external door has a lock tested to a UK standard: a TS007 3-star anti-snap cylinder on uPVC and composite doors, and a BS3621 mortice deadlock on timber doors. Make sure the cylinder sits flush, not proud.
A euro cylinder is the barrel of the lock that reads the key and drives the multipoint mechanism. On a cheap cylinder, lock snapping can beat it in seconds, so this is the single most important check on the list. Test that each door locks smoothly and the frame is solid.
“On the tools, the weak point we find most on a security check is a basic euro cylinder sticking out past the handle,” says a Kingdom Locksmith Ltd. “It is the easiest thing to snap, and the easiest to upgrade. That one change closes the most common gap.” A security upgrade service can fit anti-snap and insurance-approved locks across every door in one visit.
Windows, garage, and outbuildings
Windows and outbuildings are the next weak points after doors. Fit and use key-operated locks on ground-floor and accessible windows, secure the garage and shed with a strong lock, and never leave tools or ladders where a burglar could use them to reach the house.
Ground-floor and flat-roof-accessible windows are the ones burglars try, so check the locks work and the keys are stored nearby but out of sight. Garages and sheds often hold the tools that help force a door, so a good padlock or hasp matters, and the internal door from the garage should be as secure as any exit door.
Secured by Design, the police-backed scheme, recommends layering these measures so no single weak point lets an intruder in.
How often should you review your home security?
Review your home security at least once a year, and after any change such as moving in, losing keys, a break-in, or building work. Locks wear, habits slip, and a quick annual audit keeps every weak point covered before it is tested.
A yearly walk-through with this checklist takes minutes and catches worn locks, stiff mechanisms, and habits that have lapsed. After a move, change or rekey the locks, because you cannot know who holds an old key. The Master Locksmiths Association recommends an approved, vetted locksmith for any lock work or a full security assessment.
Frequently asked questions
What should be on a home security checklist?
Doors and locks first, then windows, the garage and shed, the garden boundary, and everyday habits like locking up and hiding valuables. Prioritise a tested lock on every external door.
What is the most important home security upgrade?
On most UK homes, a TS007 3-star anti-snap cylinder on the front and back doors. Lock snapping is the most common attack on uPVC doors, and this upgrade defeats it cheaply.
How can I improve home security for free?
Lock every door and window, remove keys from the latch, keep valuables out of sight, and never leave a spare key outside. These habits stop the opportunist break-ins that need no forced entry.
Does home security affect my insurance?
Yes. Many insurers require BS3621 locks on final exit doors, and fitting approved locks keeps your cover valid. Check your policy wording, as requirements vary between insurers.
How often should I check my home security?
At least once a year, and after moving, losing keys, a break-in, or building work. An annual audit catches worn locks and lapsed habits before they are exploited.
