About Secured by Design

Learn more about the ‘Secured by Design’ accreditation and how a Rockdoor composite door can help to keep your home safe and secure.

What is Secured by Design and why was it created?

Secured by Design is the official police backed security initiative to encourage manufacturers to put safety at the forefront of homes, businesses and properties alike, whilst giving homeowners a security accreditation for extra peace of mind.

The initiative was created in 1989 after the housing boom of the 1960-1980’s, where urgent housing was required in the United Kingdom and in the rush to deliver, often left properties with little to no real security features, ultimately lacking protection from burglars.

Intruders would often prize away the double glazing from doors and windows as this was the easiest way to gain entry.

According to the Secured by Design website, since its introduction in 1989, there has been a reduction of ‘property crime’ of over 60%, owing thanks to greater testing and manufacturing standards for companies to adhere to.

View the Rockdoor range of composite doors

The Rockdoor range of composite doors comes in 25 composite door styles, all available with 13 different door colours to choose from. So no matter if you’re looking for new front doors, back doors or even double doors, French doors or stable doors. There’s a wide range of Rockdoor composite doors available to compliment the look and style of your home.

How do Rockdoor doors achieve Secured by Design accreditation?


To meet the accreditation, there are several features that a door must include during the manufacturing process.

At Rockdoor we ensure our doors achieve Secured by Design status by implementing wire mesh reinforcing, which is an extra, added layer of protection to make a Rockdoor, that is already the most secure composite door available on the UK market, even more secure. Along with the wire mesh reinforcing we are also required to meet PAS 24:2016, which tests the security performance of our doors, from the outer frame to the glazing to ensure they can withstand forced entry from any intruders.

On the topic of glazing, Secured by Design glass in a Rockdoor must consist of 6.8mm laminated glass to meet the accreditation, however understandably, depending on your personal preference, you may require a door without glass, in which case this would not need to be met.

If you’re choosing a new composite front door, you will often require a letterbox manufactured in, and although are useful for receiving mail, can actually be a burglar’s dream. Any letterplate on an Secured by Design door must be TS008 accredited, which is a guideline set out in Part Q of Governmental Building Regulations. A TS008 letterplate prevents ‘fishing’, a method where burglars use the letterplate as an access hole to take keys and other valuables and features a security focused design to avert this.

Rockdoor Secured by Design accredited door styles

Here at Rockdoor, over 95% of our door styles can be manufactured to the Secured by Design specification! In addition to this we were also the first-ever company in the industry to achieve the Secured by Design accreditation for our French doors and double doors, which set the bar for not only ourselves, but the entire composite door market.

Almost every Rockdoor we offer is able to meet Secured by Design status, although there are certain styles of Rockdoor that we are unfortunately unable to manufacture to Secured by Design, such as our stable door range.

For absolute assurance, always check with your installation company at the time of quotation whether your door style can meet Secured by Design accreditation.

Why should I buy a Secured by Design composite door?

It is not uncommon to focus on safety when ordering a new composite door and although we place security at the forefront of all our designs, we understand there are some homeowners who may feel vulnerable and would feel more comfortable with an additional layer of protection.

Not only will this give you a police force backed accreditation, but it will also provide you with extra peace of mind – knowing that intruders will be unable to gain access to your property with a ‘Secured by Design’ manufactured composite door, that just happens to already be the most secure composite door in the UK.
