Replacement uPVC Windows – Prices, Benefits & Styles

Woman enjoying upvc windows

If you’re looking for replacement windows at an affordable price, unplasticised PolyVinyl Chloride or uPVC windows are the ideal choice for a huge number of UK homes. The use of uPVC as a replacement for your old windows continues to be the most widely recommended material used by double glazing companies and the most common material chosen by UK homeowners.

uPVC has a reputation for being the most cost effective material for window frames, surpassing aluminium and timber-frame windows. But what other benefits are there to choosing uPVC windows for your home?

Benefits of uPVC Windows

Cheaper than other materials

By far the most appealing factor of uPVC windows is the cost. uPVC frames are considerably cheaper than timber, aluminium and composite so if you’re looking to replace your windows on a budget they are usually the best solution.

Durable & easy to maintain

uPVC is the most durable of the materials available. Wood can rot and start to warp over time and aluminium may pick up rust. uPVC is non-corrosive so it will neither rust or rot and the frames will not let the cold and damp into your home. uPVC window frames are also storm proof and weatherproof as the damp cannot penetrate the surface of these frames. While timber windows may need specialist treatments over time to maintain their appearance and prevent rot, a simple wipe down with a cloth will keep uPVC at their best.

Range of styles and colour available

Historically, one of the biggest shortcomings of uPVC was in its lack of aesthetic appeal i.e. the white plastic look. Today, uPVC windows come in a range of colours – if you prefer a wood grain finish or even want your windows to look like traditional hardwood frames this can be done for extra cost.

Security options

Due to its resilience and robustness, uPVC is very reliable and trustworthy when it comes to security. The frames include a steel core making it extremely difficult to break through or damage. While aluminium is also a great option in terms of security (and preferable to timber) uPVC is far less costly.


uPVC double glazed windows have high insulation properties. With double glazing, the vacuum between the panes prevents the cold air and draughts from entering your home and the warm air and heat from escaping. As the windows are insulated you will also have fewer problems with outside noise coming in.

uPVC Window Prices

The cost of replacement uPVC windows is one of the most attractive features for many homeowners as they cost less than timber, aluminium and composite frames. The total cost will the be impacted by factors such as the number of openings, the finish, and security features.

The table below represents the average costs* for the supply and installation of uPVC framed double glazing.

Size of Window (mm) Price per uPVC Casement Window – Ground floor Price per uPVC Casement Window – Second floor
600 x 900 £500 – £600 £550 – £650
900 x 1200 £750 – £850 £1,550 – £1,650
1200 x 1200 £850 – £950 £1,750 – £1,850

To supply and fit replacement uPVC windows in the average home in the UK costs will generally fall between £5,000 – £12,000.

However, it’s important to note that uPVC can vary greatly in quality so if one supplier is drastically cheaper than another it may be a particularly durable product. By comparing several quotes you should be able to both save money and have peace of mind that you’ve settled on the right solution for your home.

uPVC Window Styles Available

There is a wide range of uPVC window types available so you should be able to find the perfect solution to suit your property and budget. You can combine the traditional charm of more traditional designs with the modern insulation, security and durability features offered by uPVC.


A casement window is attached to the frame by one or more hinges. They give an unobstructed view through the pane and allow a great deal of light into the home. They are extremely versatile as they can be made to fit almost any height and width of aperture. Casement windows are completely sealed and therefore particularly effective at keeping heat indoors and very simple to open and close.


Cottage windows are traditionally a double hung window with an upper sash smaller than the lower. They are a great choice for older homes with a more traditional appearance. They are sometimes referred to as Tudor or Georgian windows featuring horizontal and vertical strips in the glass.


A bay window protrudes from the main walls of the home and can be a bow, box or circle in terms of design. It provides the internal room with a bay and adds a really attractive feature to many homes. Bay windows are popular with many homeowners as they increase the amount of natural light which enters the home and give a great view of the outside.


Usually associated with Victorian or Georgian homes, sash windows are glazed panels which can be opened horizontally or vertically by sliding one pane behind another. This means they don’t swing outwards or inwards which can be a great choice for homes with restricted space.

Tilt & Turn

Tilt and turn windows have several benefits for the modern homeowner as they’ve been designed with convenience in mind. They open inwards and can turn sideways for easy cleaning and maintenance. They can be opened fully to allow maximum ventilation (or even to act as an emergency escape route) or just slightly for effective but safe ventilation.
