Best Security Window Bars (UK Top 3)

Security window bars and security bars on doors can provide several advantages for UK homes, garages, and outbuildings, and can improve home security by offering a robust solution and deterrent from criminals looking to break into your property.

Security bars can be installed on a DIY basis on windows or doors, and are usually installed on windows and doors where the window is large enough that if it is deliberately broken, will then offer access large enough for a person to climb through.

They are also commonly installed on windows which have an opening, where the opening if forced, is big enough for someone to climb through.

If you have windows or doors like this, anywhere in your property, and especially in areas that are hidden from public view, then window bars offer a good, cheap solution which will improve your home security arrangements hugely.

In this article, I will look in detail at home security window bars, door bars, look at the advantages and disadvantages of using security bars, look at where and where they cannot be installed, and then have a look at the best security window bars for homeowners in the UK, paying special attention to ones that can be installed by yourself.

(WINNER!) Avonstar Classic Window Bars

In first place, is the Avonstar Classic Window Bars.

These are the best security window bars you can buy and install yourself on your home.

Make no mistake about it, these window security bars are strong, heavy, durable and robust. They were much heavier than I was expecting for the price, which left me pleasantly surprised.

These bars are also well made and well engineered, and it’s clear that some considerable attention was given to the design of these bars, especially considering the clever way they have implememented the adjustable length, meaning you can make these bigger or smaller to fit your windows or doors.

These security bars will fit windows and doors with a minimum lenght of 71cm, and are extendable up to a miximum length of 120cm. You get a total of 6 bars in the pack, with all fixtures and fittings included.

What I also like is that they are supplied with anti tamper screws, which is essential if you are installing these on the outside of a window. Of course, if they were intsalled with a normal screw, a criminal has the potential ability to simply unsrew the screws and remove the bars.

No chance with these though.

  • NOW SUPPLIED WITH ONE WAY SECURITY SCREWS British made window bars pack of 6 with all fixings supplied (No. 10 Clutch screws 1 1/4 inch countersunk zinc)
  • 100% British made using locally sourced raw materials

The only dowside to these window bars is they are only supplied in one colour – white.

While this will match a large percentage of windows and doors which are usually white, it would have been nice for optional colours to be avaialble, like grey, black and brown for instance. However, if needed, these can be sprayed a different colour quite easily, if you want to.

Overall, the Avonstar Window Security Bars provide a reliable and cost-effective solution for homeowners looking to increase the security of their property. With their sturdy construction, adjustable design, and , these security bars are a worthwhile investment for anyone looking to protect their home from potential break-ins.

So, if you’re looking for a practical and cost effective solution for your home security needs, the Avonstar bars are a worthy consideration, and I regard them as the best security window bars for your home that can easily be installed on most windows and doors with minimal fuss.

(2nd Place) Avonstar Decorative Security Bars

Coming a close second, are more window bars by Avonstar, this time with a more decorative and stylish feel.

And really, they are second only because they won’t suit all homes and styles, they are for windows only and are designed to be used inside only – you wouldn’t necessarily use these externally.

That being said, if you look at some of the customer pictures of these at the bottom of the page here, then you’ll see they do add some style and substance to a window area if this is the style you prefer, and they do feel and look less like a security product and more like a feature.

Again, these are well made, heavy and robust. They come in two parts, one of which slots into the other, enabling you to have a size range between 95cm to 125cm, although I note that some customers have successfully cut them down by using a saw to make them smaller.

These come with two colour options, white or black, which is a positive especially considering my only complaint in the Classic style in first place.

  • Adjustable Decorative Window Bars Triple
  • Adjustable between 950 to 1250mm (16mm outer bar, 12mm inner bar), 65mm wide basket 320mm fixing plates, 5 mmm hole for fixing screws

Once again, these are supplied with tamper proof fixtures and fittings, they are easy to install and they offer good value for a DIY self installation product, and come fully recommended if this is more your style.

(3rd Place) Avonstar Window Grille

Wrapping up in third place, is Avonstar again, this time coming in with a grille type design making it a clean 1-2-3 sweep for this brand.

It comes in 3rd place because there is little flexibility in this product, as it does not extend or retract. That being said, it is made with a traditional window size in mind.

These security window bars are more suited to sheds, garages or outbuildings in my opinion, because they are not aesthetically pleasing in any sense of the meaning. However, they are going to do the job they were designed to do.

The measurements for this security grille are 79cm x 82cm, although they will work on smaller windows if you are prepared to have some overlap and you have suitable places on all sides to enable you to fit them to your window.

  • A lightweight but robust security grille
  • fits easily to any window surround

The Avonstar security grille is made from sturdy steel construction, ensuring durability and longevity. The powder coating also makes it easy to maintain and keep clean, ensuring that it will last for years to come with minimal potential of rust or corrosion.

Overall, this a great window bar/grille at an extremely afforadable price, but the limiting factor here is the size, as there is no additional options of different sizes offered, which is a shame.

MUST READ Security Advice: Window bars

Even after installing the best security window bars on your home, there’s always room for improvement.

A single security solution is rarely enough to deter and protect your home from criminals and opportunist thieves, especially a security solution like window bars, because they are a last line of defence security solution.

What I mean when I say this, is a criminal is already in your back garden looking to break into your shed or garden, or a criminal is already stood next to a window in your garden.

In an ideal world, you want to stop them from even entering your property through a combination of deterrents – you don’t want them trying to get past the window bars in the first place.

I wrote an extensive article on 75 Ways To Improve Home Security some time ago, but it is still the most valuable and most visited article on this site, so if you haven’t already, make sure you go and have a good read through it. Don’t forget as well, i’ve also written specific articles for specific areas of your home, like 25 Ways to Improve Garage Security for instance.

In this article, I talk about the importance of visual references and deterrents that could mean the difference between a criminal targetting your home, or walking on by because they see security features all around your home.

Things like motion detection security lighting that will come on when someone enters your garden gate or driveway can sometimes be the difference between someone entering the perimeter of your home or not.

Or some simple security signage, or a real CCTV system or a dummy CCTV system. Or improving side gate security.

The list is endless, but it’s a list you should consider, because combining security measures, both physical secuirty measures and deterrent measures, will ultimately lead to a much more secure home for you and your family.

Summary

Window or door security bars will greatly improve the security of some of your most vulnerable windows and doors in and around your home.

These window bars and grilles are also cheap, and easy to fit yourself, s home.o it is a great additional security feature for your

However, as stated, they are not a standalone security measure. Even with the best window security bars on vulnerable windows and doors, it is not bulletproof.

And once again, I will leave the top 3 best security window bars table below for your convenience.
