Why Home Security Upgrades Matter in London
London consistently records one of the highest burglary rates of any UK city. Over 17,000 homes across London and the West Midlands are burgled each year. Most forced entries take under 60 seconds. In the vast majority of cases, the method used is one that a straightforward security upgrade would have stopped.
West Midlands Police advise homeowners to treat home security as a series of layers rather than a single lock. A burglar who encounters resistance at the first point of entry will almost always move on to an easier target rather than persist. The goal of a security upgrade is not to make your home impenetrable — it is to make it noticeably harder than the next one.

Home Security Upgrades LockFirst Provides Across London
LockFirst supplies and fits a comprehensive range of home security products across London and the West Midlands. Here is a complete guide to every upgrade we provide:
Lock snapping is the most common forced entry method used across London. A standard euro cylinder can be snapped in under 10 seconds with tools available in any hardware store. An anti-snap TS007 3-star cylinder sacrifices the outer section before the mechanism is reached, making forced entry via snapping virtually impossible. We fit Ultion, Yale, ERA and Chubb anti-snap cylinders across all uPVC and composite doors.
Most home insurers require a British Standard five-lever mortice lock meeting BS3621 on timber front and back doors. If your timber door does not have this standard fitted, your insurer may refuse or reduce a claim. We upgrade timber door locks to BS3621 standard across London, providing written confirmation of the lock grade for your insurer on request.
Beyond anti-snap, high-security cylinders also resist picking, bumping, drilling and cylinder extraction. The highest standard — Sold Secure SS312 Diamond — is tested against sustained physical attack for a minimum of five minutes. Recommended by West Midlands Police for high-risk properties. We fit TS007 3-star and SS312 Diamond cylinders across London.
Insurance policies specify lock standards that must be met for a claim to be valid. We confirm the standard your policy requires, supply and fit compliant locks and provide written confirmation of the grade fitted. Many customers discover their existing locks are below the required standard at claim time — we help you avoid this
Sash jammers fit at the top and bottom of a uPVC door frame and twist across to prevent the door being forced open even if the lock is defeated. West Midlands Police recommend them as an additional layer of security on all uPVC external doors. Particularly effective at preventing door-kicking attacks. We fit them to all uPVC and composite doors across London.
A door reinforcement bar — known in London as the London Bar — is a steel bar fitted to the inside of the lock side of a timber door frame. It prevents the frame from splitting when kicked, which is how most timber doors are forced. Named after London, this is one of the most cost-effective security upgrades for older properties across the city.
Letterbox fishing — reaching through the letterbox with a stick and hook to grab keys, phones or other valuables left near the door — is a common crime across London. A letterbox guard cage fitted to the rear of the door prevents access through the letterbox entirely. West Midlands Police specifically recommend these on all doors with a letterbox. We fit standard and reinforced letterbox guards across London.
High-security handles include an anti-snap cylinder shroud and a reinforced spindle that resists drilling and forced manipulation. For composite and uPVC doors where the handle itself is a potential attack point, a security handle upgrade adds a meaningful additional layer of protection without requiring a new door.
Ground floor and accessible first floor windows are a common secondary entry point for burglars across London. Many older uPVC and timber windows have basic or worn locks that offer minimal resistance. We replace and upgrade window locks across all window types — uPVC, aluminium and timber — with tested, insurance-approved alternatives.
Sash windows on older London properties in Moseley, Kings Heath, Harborne and Edgbaston are a common vulnerability. Standard sash window fittings offer poor resistance to forcing. We fit sash stops and dual screws to prevent sash windows being opened from the outside, significantly increasing resistance without affecting normal operation.
What Is Lock Snapping and Why Does It Affect So Many London Homes?
Lock snapping is the most common forced entry technique used by residential burglars in the UK and it is particularly prevalent across London and the West Midlands.
Here is how it works in under 60 seconds: a standard euro cylinder — the type fitted to most uPVC and composite doors — has a weak point where the outer section meets the body of the lock. Using a pair of pliers or a simple snapping tool, a burglar applies force to the outer section of the cylinder. The cylinder snaps at this weak point, and the inner mechanism is exposed. The lock can then be manipulated open with a screwdriver in seconds.
The entire process from approaching the door to gaining entry typically takes under 10 seconds. It requires no specialist skills and is silent enough to go unnoticed. Most standard cylinders fitted on uPVC doors across London offer no meaningful resistance to this method.

What Our Customers Say About LockFirst Security Upgrades
After our neighbour was burgled we called LockFirst for a security assessment. They identified our cylinders were standard non-anti-snap and fitted Ultion replacements on all three external doors the same day. Really thorough and completely honest about what we needed.

Moved into a new house in Sutton Coldfield and wanted everything checked. LockFirst assessed every door and window, upgraded the cylinders and fitted a letterbox guard. Insurer confirmed we were fully compliant. Brilliant service.

Car keys stolen through the letterbox while we were asleep. LockFirst fitted a letterbox guard and sash jammers on the same day we called. Should have done it years ago.
