Don’t get overcharged on Double Glazing


Double glazing is one of the most popular insulation measures in the UK. But despite this, a survey from consumer watchdog Which? showed 40% of people found good double glazing advice hard to come by.

Double glazing is extremely popular for a number of reasons. Double glazed units will reduce your energy bills, keep your home warmer, cut condensation, limit noise pollution and slash carbon emissions.

But many avoid replacing their windows because a quarter of those polled by Which? didn’t have any idea how much double glazing would cost them. To counter this substantial problem, Which? have conducted a price guide, taking into account 15 registered double glazing companies.

Of course, each property is different so costs will differ from home to home, but the idea is to provide a rough guide for the consumer.

The tables below show the price expected for a rage of double glazing jobs in the UK. The information has been sourced entirely from Which?




What is included in the double glazing quote?

When Which? conducted their research concerning double glazing companies, 15 different traders were asked to provide the information. For each price listed above, the average cost received is shown.

So what is included in the quote? The quote is a final cost, including any discounts that were applicable. It covers the installation of white uPVC frames with B-rated glass. All materials, labour and removal of old units are included, as well as VAT and incidentals.

How much would extras cost?
