Want to save money on your energy bills? Do you idealise a more modern appearance of your house? Want to achieve both at the same time! Why not upgrade your windows with BK Windows? 

Using the highest quality products available sourced directly from our UPVC window manufacturers, you can rest at ease knowing that you have the best and most energy efficient windows for your home. BK Windows provides UPVC windows to Leicester and the surrounding areas, so we are never too far away to help.

Energy Efficiency

Saving money on your energy bills is always positive, and with your replacement windows that is guaranteed. We can assure this for you as we comply with the standards of the energy rating system developed by the British Fenestration Rating Council (BFRC). The BFRC’s scheme is the UK’s nationally recognised scheme for measuring window energy efficiency. This scheme is used in standard building regulations having to achieve a minimum of a C rating.

At BK Windows we can guarantee an A rated window as standard. This is achieved with every window being tested to a high standard, inspecting its prevention of heat loss by ensuring that drafts are kept at bay and assessing its ability to absorb the natural energy from the sun.


Here at BK Windows, we understand how important to feel safe and secure in your own home. For that reason, our standard windows all include modern security features that enable you to feel at ease. There are multiple features to our windows that ensure this be correct.

Our own UPVC formula is designed with multi-chambered construction, and are robust with welded joints to empower extra resistance against any attempted break-in, enabling you to feel safe at night.

Your UPVC handles will enable high-security steel shoot bolts to lock into every frame at two separate points, additional strength is promised. Once again, supporting the importance of security, an effective excluder device is also constructed within, to offer top-levels of protection as this prevents your windows being forced open by a jemmy. In addition to this, every opening includes a key locking security handle.

By their very nature, double and triple glazing provide greater security than single due to the extra panes of glass involved, making it significantly tougher to break. Furthermore, an added bonus is the beading internally fitted to all our windows, making it impossible to remove from the outside.

To ensure that all this is certified, all of our windows are rigorously tested, once again, giving you the reassurance that your home will ‘fight back’ against any potential threats.

What Our Think

Glass Repair Service

Double Glazing Repairs

A damaged window is something no one wishes to have, with the stress of cost, security and the rest of the weeks’ weather report, we aim to get to you as soon as we possibly can!

Damages such as misted, cracked or smashed glass can sometimes cost you hundreds of pounds to repair. Our aim at BK Windows is to repair your window initially without having to replace the whole unit, therefore saving you £££’s and still fixing the damage!

Misted Double Glazed Windows

Misted windows are one of the most common damages we see to windows. This is due to the build-up of condensation between the panes of glass and is often caused by water penetrating the seal of the glass due to it being damaged or broken. This is best repaired, by replacing the glass in the window.

Smashed Window Repair

An emergency window repair is required when one of your windows becomes cracked or smashed in order to secure your home as quickly as possible and prevent any further damage. For this reason, we can assure you that someone will come and secure your home on the same day until the arrival of your new glass panes, allowing you to feel safe in your house once more.

What’s the cost?

We can replace a glazed unit from as little as £35 including VAT, installation and a 10-year guarantee.
