Introduction: Why Chubb Locks Are a London Favourite
London is a city full of charm, but also challenges. While its busy streets and diverse communities make it vibrant, they also come with certain realities. One of those is the constant need for reliable security. Keeping your property secure is non-negotiable.
That’s where Chubb comes in. A name that has stood the test of time, Chubb has earned a well-deserved reputation across the UK for producing robust, high-security locks that blend strength, innovation, and peace of mind. London burglary attempts often target vulnerable entry points, like weak locks or unsecured windows, so thousands of homeowners, landlords, and businesses trust Chubb.
Upgrading your locks isn’t a tick box for your insurance, it’s your first line of defense. And when that upgrade involves a Chubb security lock, you’re investing in more than a product, you’re investing in lasting protection.
What Are Chubb Security Locks?
Chubb has been a cornerstone of British security since the early 1800s. Though the brand has evolved under the Union and Yale umbrellas, the Chubb name remains a symbol of reliable, high-grade security. Today, Chubb locks are built to meet modern threats, incorporating advanced engineering and compliance with insurance-backed standards.
Here’s a quick look at the types of Chubb locks available:
Mortice Locks: These are fitted into the edge of the door and are commonly found in front doors of houses and flats. Chubb’s mortice deadlocks and sashlocks are designed to meet British Standard BS 3621, a must for most home insurance policies.
Window Locks: Often overlooked but critically important, Chubb’s range of window locks includes casement and sash window options, helping secure vulnerable access points that burglars often exploit.
Deadlocks and Nigh latches: Chubb nigh latches and deadlocks provide reliable secondary locking. Nightlatches are typically mounted on the surface of internal or front doors, offering an easy-to-operate lock for everyday use with the solid backup of a key-operated deadlock.
British Standard & Insurance Compliance
Most Chubb locks meet BS3621 or equivalent standards, making them insurance-approved and widely recommended by locksmiths and insurers.
Benefits of Upgrading to Chubb Locks
Upgrading to a Chubb lock isn’t about gimmicks; it’s about serious, practical benefits that make a real difference in day-to-day safety. Here’s why so many Londoners choose Chubb:
Superior Protection Against Break-Ins: Chubb locks have hardened materials, anti-pick mechanisms, and tamper-resistant designs. They resist the most common forms of forced entry, including lock bumping, drilling, and crowbar attacks.
Built to Last: Chubb’s reputation is rooted in durability. These aren’t locks that start sticking after one winter, they’re built for long-term performance, even with daily use.
Lower Insurance Premiums: Fitting BS3621-compliant locks like Chubb can reduce home insurance premiums. In many cases, insurers will require such locks as a condition of coverage.
Peace of Mind for Landlords and Tenants: For landlords managing multiple properties, Chubb locks offer consistency, security, and confidence. Tenants benefit too—they know they’re in a properly secured home.
Respected by the Industry: Locksmiths, property managers, and estate agents know and respect the Chubb name. It’s a brand that speaks volumes in security circles.

Window Security: Chubb Window Locks
Windows are a burglar’s best friend, especially when left unsecured. While doors tend to get the most attention regarding lock upgrades, window security is just as important, particularly for ground-floor flats, basement apartments, and homes with easily accessible windows.
Chubb window locks are discreet yet incredibly effective. Depending on the style of window you have, we can supply and fit:
Sash Window Locks: Ideal for traditional wooden sash windows found in many Victorian and Georgian London homes.
Casement Locks: These attach to side-hinged windows, commonly seen in modern flats and houses.
Fanlight Locks: Useful for small top-opening windows, particularly in bathrooms and kitchens.
Properly fitted window locks act as both a physical and visual deterrent. Most burglars look for the easiest entry point, so seeing a Chubb-branded lock is often enough to make them move on.
