Building Regulations Explained

What is The Cost of New Double Glazing?

The cost of new double glazing will depend on the size, style, finish and decorative aspects of your chosen products. On average, a double glazed window is likely to cost between £350 and £400 and a uPVC door will cost around £600. This means that double glazing a 3 bed semi will likely cost between £3500 and £5000.

However, for larger, bespoke double glazing, such as a bow window, your double glazing costs will be higher.

What is The Average Price For New Windows?

The average cost for new double glazed windows is usually between £350 and £400. For a 3 bedroom semi-detached house, you can expect to pay between £3500 and £5000 to have your home fitted with new uPVC windows and doors.

If you opt for other double glazing materials such as aluminium or timber, the average costs for your new windows will be significantly higher.

The price for your new windows will also depend on their size, style, whether you opt for a wood grain finish and whether you’ve chosen any decorative additions. For large, bespoke windows with multiple glass panes, you will pay significantly more per window.

How Much Does it Cost to Install Double Pane Windows?

Our pricing tables and online quotes include the cost of installation, as well as surveying, warranties, VAT and a certificate of compliance as standard. This means that you won’t be surprised by extra costs as it is all covered in the initial quote.  

If you would prefer, supply-only double glazing companies will provide you with double pane windows for you to install yourself.

However, installing a window yourself is relatively time consuming and can be quite a difficult undertaking. Paying for installation means that you are paying for convenience and a quality fitting. You also will have to deal with the building regulations yourself, rather than having it sorted for you by your double glazing company.

What Is The Cost of uPVC Windows Fitted?

Prices for the installation of uPVC windows can vary. Each company will offer a slightly different price which is why it is so important to compare double glazing prices.

The prices given in our pricing tables and in our online quotes include the cost of fitting and surveying as well as the cost of the uPVC windows themselves. For example, a small casement window will cost between £150 and £175 including the price of installation.

500mm x 500mm White £150 – £175

Alaskan performed a truly heroic installation of a patio door and bedroom windows in what turned out to be the coldest day of the year. Despite ice and severe cold they installed both by lunchtime. The whole process was achieved with the highest professionalism with just a little fettling afterwards to make perfect. We invited in quite a few companies to quote and none showed the commitment and knowledge that Alaskan did. The prices were also highly competitive. Like others who have left reviews, we will certainly use Alaskan again. And no, I'm not related to or have any business interest in Alaskan Windows. They really are that good.
Simon W.

Alaskan Windows did such a great job that we got them back to do three more windows for us! Initially we replaced our living room sash window, kitchen window, hallway and downstairs toilet windows, but then decided that they looked so good we wanted to replace both of our bedroom and bathroom windows too. For both visits Alaskan delivered top service and I would recommend them wholeheartedly.
Laura Pilch

I am thrilled with my windows. They look gorgeous! I was also impressed by the professional approach of the sales team. Not pushy at all and providing one quote with the best deal they can offer. In my favour this far out priced other quotes whilst still offering the same quality. I highly recommend this company.
Sarah Fowler

Couldn't recommend enough. Very clear process from start to finish. Did exactly as agreed. Excellent quality value for money.

How much does double glazing cost?

Double glazing prices will vary between companies and the overall cost will ultimately depend on style and size. A 500 x 500 White uPVC casement window for example, is likely to cost £150 -£175. A bigger casement window at 1200 x 1200 on average can cost £250-300.

How can I get the cheapest double glazing in Twickenham?

When looking for double glazing at a great price, it is important to avoid rogue traders who offer subpar products and installations at prices that are too good to be true. Check that your chosen installer is FENSA or GGF registered to ensure that they are reputable businesses. If you cannot afford double glazing from a reputable company, consider opting for secondary glazing as this tends to run a lot cheaper than new double glazing.

What will my online double glazing quote include?

Your quote will include the cost of the double glazed units themselves, as well as installation, surveying, a warranty, VAT and a certificate of compliance. This means you get a complete price upfront so you’re not surprised by additional fees further down the line.

How much is a triple glazed window?

Triple glazed windows can provide your home with additional soundproofing and thermal performance, but will always cost significantly more than their double glazed counterparts. A triple glazed window costs around £110 more than a double glazed window. Triple glazing is really only a worthwhile investment if you are using it as a replacement for old double glazing or single glazing. If you are replacing modern double glazing you are unlikely to see enough of a difference in the quietness or warmth of your home to justify the extra cost.

Are uPVC patio doors made to measure?

Double glazed patio doors are available in a wide range of sizes but whether or not they are bespoke, depends on your chosen installer.
