How to measure your windows

When taking the measurements for your new windows remember to do so in millimetres (mm). Where possible you will need to measure the aperture or brickwork opening on the outside of your property. Any windows above the ground floor will cost more to replace as the window fitter will need to use scaffolding to access them. It’s possible that a company may offer a discount if you need more than 5 windows so if you’re having a total overhaul remember to ask the question!

Double Glazing vs Secondary Glazing

Double glazing prices sit at around £350 – £600 per window. However, double glazing prices will vary from installation to installation and will depend on:

• Size of the window
• Frame material
• Style
• Type of glass
• Rates charged by the installer – compare quotes to find the most competitive price

Thanks to being an effective insulator that will help to keep your home warmer and reduce outdoor noise, double glazing is well worth the investment. The Energy Saving Trust found that typical gas heated homes across England, Scotland and Wales could be saving up to £160 a year – just by having double glazing installed.

If the cost of double glazing isn’t a realistic option for you, secondary glazing could be the next best option for you. This involves adding a second pane of glass to single glazing which is fitted on the inside of the window. It’s a cheaper choice and will reduce the heat loss and noise pollution associated with single glazing, but it’s not as effective as double glazing.

Comparing window quotes and prices

Before you begin inviting tradespeople or salespeople into your home it’s a very good idea to do your own research. Take a look around at the options on the market, ask friends and family for recommendations and possibly even neighbours with similar homes if they’ve had new windows installed recently. This will give you a great foundation so that you can give them a clear steer from the start as to what you’re looking for in terms of frame materials and style of windows.

To provide accurate quotes for your new windows the sales representative or tradesperson will need to visit your home. Don’t let any trader pressure you to agree to a quote based on ‘today only prices’. A reputable company will provide their best quote and leave you to consider it. They should also be registered with FENSA or the GGF.

What should a quote for new windows include?

When getting quotes for your new windows, the total price quoted by each installer should include:

• A full survey of your home
• The window frames & external cill
• Evidence of energy efficiency rating
• Any security features
• Glass panes (standard, toughened, obscured)
• Handles
• All installation / labour costs
• Trims, fixings, silicones and sealants
• Registration with industry body such as FENSA or Certass and relevant certification
• Removal and disposal of your old windows

We advise you get as many quotes as you can but it’s really important that you compare more than a single quote to be sure you’re getting a competitive price. A very good tactic is to consider quotes from both a leading installer like Everest, Anglian or Safestyle against a local, independent window fitter. Remember to compare a like for like service so you can see the difference in window prices and ask specific questions.
