From Our Website

Thornhill Security Ltdis an established Lock and Safe company based in Kingswood, Bristol with over 40 years of experience in providing specialist advice on safes and locking solutions for the domestic and commercial markets throughout the South West and across the UK. In addition to the sale of a wide range of security products including Safes, Vaults, Strongrooms, Access Control and Master Key Systems, Cabinets, Lockers Security Grilles and Cages as well as locks and locking solutions of all shapes and sizes we provide a full installation and maintenance service and can also supply and fit refurbished or second hand safes.

If you don't have the budget for a brand new safe, you may be interested in finding out more about buying a reconditioned second-hand business or home safe. Whilst this is a completely viable option, it's important that you buy it from a reputable supplier to ensure that the product offers the same level of protection to a brand new safe. As a specialist safe provider to Government Agencies and commercial clients along with domestic users, we carry a wide range of used safes, which can offer a good value alternative compared to buying new and will be insurance approved.

Demountable Vaults and strongrooms are all about ultimate security in a sizable space where a standard sized safe would not suffice. The installation of vaults or strongrooms are ideal when you have a lot of data, items or assets that you need to ensure are locked up securely and are only accessible by those with the appropriate authority. We typically see these types of industrial-sized security products used by organisations such as banks, pharmaceutical companies, chemical companies, art dealers, auction houses and more.

At Thornhill we pride ourselves in offering a complete safe purchase and installation service regardless of whether you need a small domestic safe to protect your valuables and important documents at home or are a business looking for a commercial safe. With over 40 years of experience and a physical retail premises in Kingswood, Bristol we truly understand the requirements of our customers and offer a level of customer service often missing from purely online operations. We stock a wide range of safes from leading manufacturers including SMP, Chubbsafes, Dudleys, Burton Safes, Securikey, Yale, ABUS, ERA, Guardian and more.

Gaining access to a safe that has been locked shut is not an easy task; after all they are designed to be impenetrable without a key or code. In addition to this, the advancements in safe technology have made gaining access to a locked safe almost impossible without specialist knowledge and equipment. At Thornhill Security, we offer a full safe opening service, whether you discover a safe when moving into new premises, or have lost the keys or access code to your own safe, we can help. Unlike many locksmiths, we are, in some cases, able to manipulate safe locks in order to open them without causing excessive damage to the lock, meaning the safe will still function after being opened.

When you purchased your safe it gave you the peace of mind and security you needed for your valuables and important documents but is that still the case? Whilst modern safes are built to last if you've had yours for a long time it might need some attention to ensure it continues to provide the high level of security you need. Perhaps the safe doors are in need of repair or you've simply lost the keys and cannot access the contents. Whatever the problem, our highly qualified team of engineers can provide assistance with the repair or refurbishment of your existing safe, vault or security cabinet to ensure you continue to get the same level of protection you are used to without the cost of purchasing a new one.

These include scenarios where cash and valuables are kept onsite, such as festivals and music concerts, in venues like art exhibitions and film sets or when valuables are being transported whilst relocating. At Thornhill, we are proud to be able to offer safe rental services, allowing our clients to hire out a safe from our range on a temporary basis from 1 week to as long as 6 months. Renting a safe from Thornhill Security gives you peace of mind, enjoying the benefits of our high-end safes at a fraction of the price.

How secure are your premises? Whether you own a shop, garage, warehouse or have premises that store high-end goods such as jewellery or expensive equipment you no doubt you have quite a bit of security at the front of the property, but what about at the rear of it? It's important to think about both the rear and the front of your premises when it comes to security - an obvious thing to highlight, but often the rear of a premises can be the weakest entry point for a determined intruder. Away from the view of passers-by and perhaps a little less well lit, it offers would-be thieves a quieter spot to try and force entry.
