Around 6.7 million crimes were recorded by police in England and Wales in the year to September 2024, and while that headline number can feel overwhelming, what matters more for someone buying an apartment is understanding the specific risks where you’re looking. I’ve spent years covering UK property, and the question I hear most often isn’t “is this area safe?” — it’s “how do I actually check, and what do I do about it?” The answer is more practical than most people realise.
You can’t change a neighbourhood’s crime rate overnight, but you can choose a flat that’s built to handle it. The key is knowing which security features actually matter and which ones are just marketing. Here’s what you actually need to know.
Before you even start viewing properties, it’s worth understanding how location affects more than just convenience — it directly shapes the security measures you’ll need to prioritise. A smart video doorbell, for instance, can give you eyes on your front entrance without stepping outside, which is especially useful if you’re buying a ground-floor flat where foot traffic is higher.
What makes a flat inherently safer than a house
Most people assume all properties face the same burglary risk, but that’s not true. Flats benefit from several layers of security that houses simply don’t have. A typical flat has a main building entrance with a buzzer or intercom, a private front door, and often a gated entry point or CCTV in communal areas. That’s two or three barriers before an intruder even reaches your door. Add in the fact that neighbours are close enough to hear unusual activity, and you can see why burglars tend to target houses instead.
That said, the quality of those barriers varies enormously between buildings. A 1970s council block with a broken intercom and a flimsy front door is a very different proposition from a modern development with secure entry and concierge. What I’d do is check the building’s communal entrance on your first viewing. If the door doesn’t close properly or the buzzer system looks outdated, that’s a red flag you can’t ignore.
If you’re looking at a flat with a wooden front door, a British Standard 5-lever mortice deadlock is one of the most cost-effective upgrades you can make. It’s insurance-approved, pick-resistant, and very hard to force open — exactly the kind of upgrade that pays for itself in peace of mind.
Why ground-floor flats need a different approach
Ground-floor and basement flats are 48% more likely to suffer a burglary than flats on higher floors, according to research from Latham’s Steel Doors. That’s not a small difference — it’s nearly half as likely again. The reason is straightforward: ground-floor flats have more entry points that are accessible from street level, and burglars don’t need to navigate communal areas or stairs to reach them.
If you’re buying a ground-floor flat, you need to think about security differently. Windows become a primary concern, not just doors. A forceful kick on a wooden door can break the lock or split the frame entirely, and a big blow to a uPVC door can cause it to collapse or tear away from the frame. Steel front doors are now available for residential use and offer much better resistance, but they’re not always an option in leasehold flats where you can’t change the external appearance.
What I’d do in this situation is prioritise window locks first. They’re cheap, easy to install, and most insurers expect them anyway. Then look at the front door lock — if it’s a standard euro cylinder, upgrade to an anti-snap TS007 3-Star cylinder. Lock snapping is extremely common, and a £30 cylinder upgrade can prevent a break-in that would cost thousands in damage and loss.
For ground-floor flats with a side or rear door, treat that door with the same seriousness as the front door. It’s a common oversight, and burglars know it. A Yale Smart Home Alarm can cover both doors and windows with tamper detection and wire-free sensors, making it a practical option for flats where you can’t run cables.
Where buyers get security wrong
I see the same patterns repeating. Buyers either ignore security entirely because they assume flats are safe, or they go overboard on gadgets without fixing the basics. Neither approach works.
Relying on the building’s security without checking it
It’s easy to assume that because a building has a secure entrance, your flat is safe. But communal doors fail, buzzers break, and CCTV systems go offline without anyone noticing. I’ve seen flats where the main entrance door has been propped open for months because the lock is faulty. If you’re buying, ask the seller or managing agent about the last time the communal security was serviced. If they can’t answer, that’s a problem.
Ignoring window locks on upper floors
Upper-floor flats are less likely to be burgled, but that doesn’t mean windows should be left unlocked. Burglars can access upper floors through fire escapes, balconies, or even adjacent roofs. A surprising number of flat burglaries happen through unlocked windows on the second or third floor. Every window should have a lock, and you should check them before you exchange contracts.
Overlooking the trading allowance trap
This one catches a lot of people who rent out their flat occasionally. If your rental income sits just above £1,000, you lose the trading allowance entirely — the full amount becomes taxable, not just the excess. It’s a threshold issue that’s easy to miss, and it can turn a small side income into an unexpected tax bill. If you’re planning to rent out your flat even occasionally, factor this into your budget.
Not using crime data in negotiations
High local crime rates can be legitimate leverage in price negotiations, but most buyers never bring it up. If the area has a burglary rate above 10 per 1,000 households — which is considered high risk — you have a concrete reason to ask for a reduction. The key is having the data ready before you make an offer. Use police.uk or the Home Checkup Crime Map to get street-level figures, and reference them calmly during negotiations.

| Area Type | Crimes per 1,000 residents | Burglary risk level |
|---|---|---|
| Urban | 80–150 | Moderate to high |
| Suburban | 40–80 | Low to moderate |
| Rural | 20–50 | Low |
If you’re buying in an urban area with a crime rate above 100 per 1,000 residents, you’re not being paranoid by investing in extra security. A home security starter kit with outdoor cameras and a video doorbell gives you coverage of your entrance and any vulnerable points without needing to drill into communal walls.
How to secure your flat properly — a practical guide
Writing about topics like this takes real time and research. If you buy something through an Amazon link on this page, I may earn a small commission — at no extra cost to you. It’s one of the things that makes it possible to keep BritWealth free to read. I only link to products that are genuinely relevant to the article.
Start with the front door lock
Your front door is the most obvious entry point, and it’s where most burglars will try first. If you have a UPVC or composite door — which is standard in most modern flats — you need an anti-snap euro cylinder lock rated TS007 3-Star. Standard euro cylinders can be snapped in seconds with basic tools. A 3-Star cylinder is designed to break at a weak point that leaves the lock mechanism intact, so even if the cylinder is snapped, the door stays locked.
If you have a wooden door, a British Standard 5-lever mortice deadlock is the better choice. It’s harder to force, pick-resistant, and drill-resistant. Most insurers will require at least this level of lock for buildings insurance, so it’s worth checking your policy requirements before you buy.
For a retrofit option that doesn’t require changing your existing lock, a Nuki Smart Lock Pro fits over your existing cylinder and adds remote access, auto-lock, and activity logs — all without drilling or replacing the door.
Secure every window, especially on the ground floor
Window locks are cheap, easy to install, and often required by insurers. For ground-floor flats, consider security shutters or bars if the building allows them. For upper floors, standard key-operated window locks are usually sufficient. The key is to make sure every window that opens has a lock, and that you actually use it. A surprising number of burglaries happen through windows that were left unlocked “just for ventilation.”
If you’re in a ground-floor flat with a side or rear door, treat it like a front door. Fit the same level of lock, and consider a door sensor that alerts you when it’s opened. A TECKNET Door Alarm Sensor is a simple adhesive-mounted option that sounds a loud siren when the door is opened — no wiring required.
Use lighting and visibility to your advantage
Motion sensor lights near entrances and parking areas are highly effective at deterring burglars. They remove the cover of darkness that intruders rely on. For flats, you’ll need to check with the building management before installing anything in communal areas, but you can usually fit a battery-operated motion light on your own balcony or outside your private door.
Maintaining shrubbery and hedges is also important. Overgrown bushes near entrances give intruders places to hide. Keep them trimmed so that your entrance is visible from the road and from neighbouring flats. Communal gardens that are unkempt and obscure views are a security risk for the whole building.
Check the building’s communal security
This is the one area where you have limited control as an individual owner, but it’s still worth investigating before you buy. Ask about the intercom system, the condition of the main entrance door, and whether there’s CCTV covering the entrance and parking areas. If the building has a concierge or a secure entry system, find out when it was last serviced. A broken intercom is a security gap that affects every flat in the building.
If you’re buying in a building with outdoor storage areas like bike racks or sheds, check whether those are secured. A battery-operated shed alarm can protect belongings without needing mains power, and it’s a small investment that prevents a frustrating loss.
For a comprehensive view of what your building’s rules allow, it’s worth checking the leasehold rules on security modifications before you install anything. Some buildings restrict what you can attach to external walls or communal areas.
Future-proof with smart technology
Smart security devices are becoming standard in flats, and they offer advantages that traditional locks and alarms don’t. A video doorbell lets you see who’s at your door without opening it, and many models record footage that can be used as evidence if needed. Smart locks can be set to auto-lock after a certain time, so you never have to worry about whether you left the door unlocked.
The key is to choose devices that work within your building’s constraints. If you can’t drill into communal walls, look for battery-powered options. If the building has thick concrete walls, make sure the wireless signal is strong enough. A wireless security kit with a doorbell and cameras can cover most of your needs without any permanent installation.

Security isn’t about being afraid — it’s about being prepared. The flats that get burgled are almost always the ones with obvious weaknesses: a broken lock, an unlocked window, a dark entrance. Fix those, and you’ve removed yourself from the easy-target list. Start with the front door lock and the windows, then work outward from there.
