We reveal the typical cost of double glazed windows and doors, so you don't get caught out and overcharged when you get double glazing quotes.
Before you start getting quotes for double glazing, having a clear idea of double glazing costs will help ensure you don't pay more than you need to.
That's why we’ve worked with the Royal Institution of Chartered Surveyors (RICS) to find out the average cost for different types and sizes of double glazed windows and doors.
There are plenty of variables that affect costs and every home is different. But our pricing research – which includes replacing windows and doors on the ground level and also higher up - should give you an idea of what to expect to pay. We’ve also spoken to experts to find out what elements can cost extra and drive up your bill.
The tables below show how much you should expect to pay for various double glazing jobs. This includes varying sizes of sash and casement windows and different materials, from uPVC to hardwood. You'll also see the prices for different types of hardwood double glazed doors and Georgian PVC doors.

The tables below show prices for a range of different doors. From simple, wooden double glazed doors, to more ornate ones, such as Carolina doors - these have curved panels of glass just at the top.
You can also see prices for different grades of new ironmongery, and the cost if you use old fittings. In the bottom table, we show prices for plain uPVC doors, where a new frame and door are being added.
What our calculations are based on
To arrive at these average costs, Royal Institution of Chartered Surveyors (RICS) uses cost data from its Building Cost Information Service database, where costs are collated from a variety of sources and analysed.
Material costs are based on the best trade prices from a range of suppliers across the UK, which are then benchmarked to reveal the best national average. Labour rates are based on the current Building and Allied Trades Joint Industrial Council wage agreement. It then uses this data in a standardised model of the average double glazed window and door types and sizes. Prices correct as of September 2017.
