Set a budget

Do your research
Make sure you understand what type of window you’re looking for. Prices can vary hugely depending on the type of glass and frame. Always try to compare similar windows, so you know which quote is the best price.
Think about the savings

You should always get a range of quotes for double glazing to let you compare the cost of using different companies.

Things to watch out for
- Get lots of quotes! Some double glazing companies may use sales tactics to pressure you into purchasing windows on the spot – don’t fall for these. Shop around and make sure you get several quotes from local and national companies.
- Pay attention to the specification of the window. Check the specifications of the windows that you’re being quoted for, and be clear on what type of window you’re looking for. You can use the double glazing energy efficiency rating scale as a guide and compare the U values of windows to understand their thermal efficiency.
- Non-standard window openings can add significantly to the cost of your replacement double glazing. This is because these will often need large amounts of replastering and making good around the window frame. This means that the fitting will take longer and be more expensive.
