Window fitting cost in 2020

The windows in your property don’t just have a big impact on the look of your home, they also play a major part in its insulation and energy efficiency. While in years gone by, pushy double glazing salesmen were a common cliche, now the options for upgrading your windows and getting them installed are much more accessible. Before you get started on changing your windows, you’ll want to know more about the costs involved, so we prepared this guide to help show you what you need to know.

Double glazing window fitting prices

Small uPVC double-glazed windows, which are made up of two layers of glass with a layer of gas in between, surrounded by a plastic frame, can cost as little as £200 for a simple casement window fitting. Prices for more standard-sized windows, as found in living rooms or bedrooms, will cost between £400 and £600 for a single-window fitting. Bay windows are the most complex to fit and the single uPVC bay window can cost up to £800 for a fitting.

It is also important to mention that, windows on the upper floors can require scaffolding which also affects the price of the fitting.

For uPVC sash windows (with a sliding pane), a price of around £400 is fairly typical, while “turn and tilt” windows, where the central pane moves, will be similarly priced. To calculate the cost of windows for an entire home, it will depend on the number of windows being fitted. Also, the size of the windows and the type of window chosen is important, but for an average three-bedroom semi-detached home, the cost may vary from around £1,500 to over £4,000 just for a fitting.

Wooden double glazing window prices

Wooden, or timber window frames, can be divided into softwoods, such as pine, and hardwoods, such as oak and meranti. Traditional timber windows will be more durable but will be a bit more expensive to install due to their weight. Which quite often make them unable to fit with one man. For a small timber casement window, the price would typically begin at around £300. Larger sash windows will cost between £300-500 for fitting. Very large sash or casement windows can cost upwards of £600-700 for a fitting depending on the size and weight. It’s typical that large fully glazed timber windows can weigh more than 100kg and cannot be fitted by one or even two fitters. Altogether, replacing the windows in a house can cost between £1.500-4000 just for a fitting.

Other costs to consider

There are a number of ways to go about replacing your wood windows in the UK, from buying directly from a national firm which will supply and fit the windows, to hiring a smaller, local firm who will source the windows themselves. One thing to look out for is firms that are registered with national bodies FENSA or CERTASS, which aim to raise the standards of the industry and promote quality tradespeople. Although the double glazing sales industry isn’t like it once was, it still pays to be wary of anyone doing a “hard sell” or promoting last-minute offers that seem too good to be true. You should never feel pressured into making a large purchase like new windows or get rushed into making choices that you would not otherwise make.
