UPVC windows – benefits, cost and building regulations

UPVC windows can really transform the look of your home; as well improve security and energy efficiency.

uPVC windows are the most
popular kind in the UK

“The most popular type of window frames are definitely uPVC,” says Tom Rawcliffe, from Dee Windows in Cheshire. UPVC stands for un-plasticised polyvinylchloride (sometimes referred to as Vinyl or ridged plastic) and is a common window and door frame material.

Benefits of installing UPVC windows

UPVC windows are:

• Energy efficient – because uPVC keeps the heat in and is an insulating material; “they can reduce heat loss from your home,” says Graham Dear, from Addlestone Windows and Conservatories in Surrey. This helps to lower both your fuel bills and carbon footprint.
• Low cost – in comparison to other window frame types like wood, uPVC is a cheaper option.
• Good for reducing noise pollution – the thickness and insulating nature of uPVC window frames will reduce noise pollution, which is especially handy if you live near a main road.
• Durable – “uPVC is hard wearing and durable, much more so than wood frames,” says window installer Tom. Unlike other materials, uPVC won’t rot; warp or crack, even in extreme conditions and is fire resistant.
• Long lasting – good quality uPVC windows can last around 35 years
• Good for security – “Because it is such a tough material, uPVC provides good security,” explains Graham. UPVC windows can be fitted with extra safety features like locks and childproof hinges.
• Attractive – new windows will appeal to buyers and may even increase the value of your home.
• Low maintenance – the occasional clean is all your uPVC windows will need; “Unlike wood frames which need repainting or staining regularly,” points out Tom.
• Available in different colours and finishes - this means you can choose uPVC windows to suit your homes existing style. UPVC frames with a wood grain finish are popular.

Planning permission for uPVC windows

Have your uPVC windows installed by
a member of BSI, CERTASS or FENSA

Planning permission is not normally needed for installing new uPVC windows, unless you live in a listed building or conservation area, in which case you need to check this with your local planning authority. If you are putting windows into a commercial premise, new build, porch or conservatory, you will also need to go through the local building authority process.

Building regulations for uPVC windows

You must adhere to building regulations when installing new uPVC windows. According to section L of the building regulations you should install windows with a low U-Value (this measures the rate at which heat is lost through the window) to ensure that your home is energy efficient.

The best way to abide by the building regulations is to hire an installer who is registered with BSI, CERTASS or FENSA. They will issue you with a certificate stating that the work has been performed to necessary standards and inform the local authority of this. “If you don’t hire a registered installer you will have to apply to the authority yourself and pay for it,” says window specialist Tom.

Cost of uPVC windows

The price of windows would vary depending on the amount, size and type required, you should get at least three quotes. According to the Halifax Home Improvement Survey, the average cost of new windows was £3,700.
