Best double glazing companies: How to buy double glazing

Double glazing salespeople often have a dubious reputation - but the extent to which this is fair varies hugely.

How to get double glazing quotes - and sidestep sales tactics

When you're buying double glazing, it's important to get quotes from more than one company (aim for three) and not to sign a contract on the spot.

We've found that window salespeople frequently quote a higher price to begin with, which they drop over the course of their sales visit. The price you're quoted could drop by 75%, or over £10,000, during a sales pitch. Be wary of a company using these sorts of tactics, or anyone who asks for a large deposit upfront.

In order to get the most directly comparable quotes, make sure each company gives you prices for exactly the same products and materials. Compare the costs of what is included as standard and what is priced up separately as an optional upgrade or extra. Don't rush your decision; take time to look at the details and make a fully informed choice.

Double glazing quotes: top tips from installers

'Do your research: having a good idea of your requirements before getting a quotation gives you a much more tailored price first time around.'

'Choose a local business in your area - someone you can visit face-to-face and build a relationship with. Local businesses are more conscious of the need to uphold their reputation and, if problems arise, are more likely to resolve the matter quickly.'

Don’t use a company that only supplies a mobile phone number and not a landline. Only having a mobile number indicates that they don’t have a sound base - they must have staff on hand to handle any problems from day one

'Have as many windows as possible replaced at the same time as this should reduce the cost.

Double glazing prices

Double glazing can cost very different amounts depending on whether you use a local or national company, how many windows you're getting installed, the type of window and type of frame. 

Find a reputable double glazing company

Our double glazing company reviews will tell you how major national brands compare to independent installers in areas such as value for money, the quotation process, and of course the quality of the windows. We'd recommend using a company that's been around for 10 years or more.

If you decide to use an independent local company, be sure to ask friends and family for their recommendations. 

Competent person schemes: Fensa, BM Trada and Certass

It's a good idea to choose a double glazing installer that is registered with Fensa, BM Trada or Certass. Membership of competent person schemes such as these means that companies can self-certify that their work complies with building regulations.

In England and Wales, new and replacement windows must meet a certain level of energy efficiency, and you need to get a certificate to show that your windows comply with these regulations. An installer registered with one of the self-certification schemes will issue this certificate for you - otherwise your council will need to come and check the work.

For the Channel Islands, Northern Ireland and Scotland, contact your local authority for information on applicable regulations for windows.
