Cost-effective double-glazed windows that don’t compromise on quality

Even though the style of our windows is highly adaptable, an area they do not compromise on is their performance. Utilising the latest technologies, our windows excel in terms of thermal efficiency and security. This means your home will be a safer and warmer place as soon as they’ve finished being installed.


At Budget Windows, we boast three fantastic window styles, each with a range of design features and general benefits. Our range of window styles include the ultra-versatile casement, elegant flush sash and smoothly-operating sliding sash, with each available in a selection of different materials, such as uPVC, aluminium and timber. So no matter if you live in a rural cottage or a deluxe apartment, we have a window to suit any type of surroundings and aesthetics. After finding your perfect style, you can truly make your new windows customised to your own requirements. Whether you choose the material they are constructed from, their colour, furniture or glazing – there are a multitude of options.


All of our selection of windows feature multi-point locking systems to increase their respective levels of security. They also have options to have additional security hardware attached to them, such as anti-bump cylinder protectors and hinge protectors. Therefore, our range of windows will be sure to give you peace of mind, not only against potential intruders but also against harsh weather due to their durability.

Energy efficiency

Our selection of windows are all incredibly energy efficient, with low U-values allowing fantastic thermal transmittance and heat retention. For example, the flush casements from Deceuninck have a Window Energy Rating (WER) of A+, while the Residence 9 collection achieve U-values as low as 0.8 W/m2K. Additionally, our timber sash windows feature argon gas-filled glazing with a warm spacer bar, meaning they can achieve U-values of 1.1 W/m2K. Each of our choice of windows performs incredibly well in terms of thermal efficiency, with many being able to achieve WERs of up to A. Of course, the benefits of thermal efficiency include helping to provide a warmer home in the winter as well as making some potentially considerable savings on your heating bills.

Double glazing

Double glazing is available across our three window styles and comes with a host of benefits that will significantly increase the performance of your windows and home as a result. Also, double glazing can seriously add value to your property because of the range of benefits that it is able to offer. Make sure that you have a good idea of what you want when it comes to buying your double glazing. As there are so many options, in terms of the customisation available, it is important to ensure that you are happy with everything. We will be happy to speak with you regarding your visions and requirements – get in touch with us today. You can even get triple glazing for your windows to get a further performance boost.

'Excellent service throughout and a fantastic product. Tony was such a great help when we were choosing our doors and windows, and very flexible when we wanted to make changes. The overall cost was very competitive and I'd have no hesitation in recommending budget to friends in the area.'

Ian Hinchliffe

'It's not often you get a truly personal service these days but that is what we received from Ben and his team. His knowledge, professionalism and attention to detail reassured us completely. We were kept informed throughout the process and everything was delivered on-time and within budget. '

Geraint Whitley

'We needed new windows in our Victorian house as the original ones were incredibly draughty and no longer opened properly. Our priority was to get efficient modern windows which were in keeping with the style of the property. Tony at Budget Windows put a great deal of effort into advising us and designing our windows. The fitters were really tidy and trustworthy and we are thrilled with the results.'

Zoe Davies

'Absolutely brilliant from beginning to end – amazing fitters – two windows and patio sliding doors – great company to deal with – thank you.'

Budget Windows Customer

'Ben was excellent in assisting us to choose the right windows, guiding us through the different options available and understanding our requirements for a 1930s house. He delivered ahead of schedule and the fitting was excellent. One minor production fault was noted and corrected very quickly and the windows look fantastic. Real high quality at a fantastic price. We did a lot of comparisons and some came in at 3x the price we paid and I didn’t see the difference in quality, nor was the customer service matched. Highly recommend Budget Windows.'
