Double glazing, either doors or windows, is a great way to cut down on your energy bills, not to mention reduce road noise and they can even reduce condensation, so you don’t end up with puddles on your window sills on cold winter mornings. However, like most energy saving initiatives, installing double glazing isn’t cheap, so you need a decent sum of cash to cover the costs up front, or a credit card that hasn’t been maxed to the limit. On the other hand, the long-term savings can more than make up for the initial expense. The question is how much should you pay for double glazing?
And the answer is …
It depends on several factors, including the size of your windows, how many windows you have, the type of frame you want and whether you’re going to include your front and back doors.
House Extension Online provides some up-to-date (estimated) prices on double glazing for uPVC casement and sash windows and doors. It’s important to bear in mind that these average prices aren’t representative of the entire UK, as independent double glazing companies determine their own costs.
On average you’re looking at:
- £250 per uPVC casement window (60cm x 90cm)
- £350 per uPVC casement window (120cm x 120cm)
- £500 per uPVC sash window (60cm x 90cm)
- £600 per uPVC sash window (120cm x 120cm)
- £900 per uPVC door
CompareMyLocal.com goes into greater depth with double glazed door prices:
- £240 per standard uPVC door
- £249 per uPVC back door
- £390 per uPVC French door
- £455 per uPVC stable door
- £580 per uPVC patio door
- £75 per uPVC side panel
Then there are the extras. For example, according to CompareMyLocal.com, wood-effect and aluminium frames cost more than regular white frames (between 15% and 50% more), A-rated glass costs more than B-rated glass (which costs more than C-rated glass) and you might end up paying more if the windows to be double glazed are up two or more floors.
Too rich for your blood?
There are some alternatives if that sounds a wee bit expensive. You could, for example, save on labour costs and attempt a DIY double glazing installation. You can go the proper double glazing route if you choose, but it can be rather challenging so you need to be very confident of your handyman skills.
The easiest way to approach double glazing from a DIY perspective is to buy a secondary glazing kit. According to Energy Saving Trust, secondary glazing is as simple as fitting a secondary pane of glass inside an existing window. It’s not quite as good as the real deal, but it gets the job done.
You can also take advantage of The Green Deal loans to make installing double glazing more affordable. They aren’t technically grants, as the loan amount it tacked onto your energy bills, but you have up to 25 years to pay it off and if you move, the next occupant takes over the remaining cost of the double glazing. However, according to Green Deal Initiative, you can get a double glazing grant up to the cost of £10,000, so it’s probably a good idea to find out what’s applicable in your area.
Final bit of advice
Get quotes from several double glazing companies before you choose your provider – and research all of them online. Read reviews and pay careful attention to the complaints vs. praise. Some companies are also willing to negotiate, especially if you tell them that someone else can offer a better price.
