Average Double Glazing Prices 2024
How much does double glazing cost?

Prices start at around £200 and rise up to £700, it really depends on the style and type of window you choose to have. A single casement window with a uPVC frame starts on the lower end at around £200, whereas a sash window starts from £450 and is more on the costly side.

But by researching what you want will lead you to have a more realistic expectation of costs. Therefore you can budget accordingly for your new windows or replacement windows.

At a glance the costs can vary on the different design you want. Looking at a single 200cm x 200cm window installation, the prices would be:

Of course, all these prices are estimated and different companies can provide different quotes for their installation services. So these figures should be taken with a pinch of salt.

On top of these costs are other variables such as colour, handle type, the type of finish on the windows, all these added extras push up the cost.

It’s also important to factor in the cost of the glass. If you were to go with the specially treated glass which – if shattered – breaks into harmless crystals. Whereas normal glass breaks into shards which is more dangerous. The special glass, although offering more safety, is more expensive as a result.

The table below gives a rough estimate of the cost for uPVC Casement Windows.

Remember, these prices are only a guide and not 100% accurate as many companies move between these prices when quoting the work as they may have a minimum order price which could affect how they quote their windows.

We advise to buy windows for the whole house rather than individual windows. The reason for this is because it saves costs as you may pay more for a window if you buy it individually.

As with all our advice in this article, it’s best to shop around for the best deal to get the best quotes available.

Both! It’s best to consider both national and local double glazing installers for your home renovation project, or if you’re just updating your home. Get quotes from both local and national double glazing installers and compare which quotes fit within your budget.

Whilst double glazing cost is important, so is the support you receive throughout the project from start to finish.

You might prefer a local company so that you can have more of a personal service, although you might prefer a national company who can simply get the job done and treat is as any other job.

However, national companies may run promotions and discounts from time to time, financing options are more available from national companies. These could save you costs overall, whereas, you might be paying more top level prices for a smaller company but the level of personal service you receive could be greater than that of a national company.

The same variables apply, you may get charged extra for style, design, finish and other accessories. Customisation can also be quite costly and bump up the price. But as long as you have budgeted for these options with a realistic figure, then you should be fine.

As with new double glazed windows, replacement windows can also be quite expensive and is a competitive market. So it’s best to find multiple quotes from different companies in and around your area, then, compare those quotes from national quotes which you could enquire about.

By doing so, you get the best price available for your budget and your project.

Comparing Double Glazing Prices

Researching has never been more important than it has in the home improvement market. It will make you more in-tune with double glazing prices and put you in a better position to be able to buy double glazing windows at a competitive price.

Furthermore, your knowledge of the different types of window styles and designs will improve as you get to understand the different costs for the different styles.

There are many things to consider when buying double glazing, these include;

Energy Efficiency Ratings

In the long run investing into high energy rated double glazed windows can reduce energy costs and in turn save you money, but upfront they are likely to be more expensive.

Double glazed windows are ranked on a simple grading scale with G being the least energy efficient and A++ being the most energy efficient. So when shopping around, consider budget but also consider energy bills for the next 10 years plus as you will more than likely be keeping your windows for that amount of time at least. This is why we would advise on spending a little more money to get the A++ energy rated windows.

Types of Glass and Colours

The type of glass you choose to install with your windows will also impact the double glazing cost. Whether you go with toughened, frosted or self-cleaning, they each come with benefits and each add to the cost of your double glazing. Although in some cases, the toughened glass may be a requirement. In such cases, it’s best to speak to your installer for specifics and any other questions you have, as they will be able to best advise you on what to do.

The colour of the frames will also bump up the price. White is the most popular,  however there are many colours to choose from. Contemporary colours such as black, grey or green are available to use. There’s even different effects and finishes such as the wood effect which can look nice but comes with a higher cost.

Accessories and hardware is also available for your windows. Different types of handles, colours and styles to suit your property rather than look out of place with the rest of your house.

It’s best to compare prices and quotes of different double glazing companies to make sure you’re getting a good deal. Then if you already have the budget at your disposal you can look at installing your new or replaced double glazing windows. If you need to look at other alternatives,  a lot of companies provide schemes such as financing options which include monthly instalments to pay for double glazing and other financing repayments. Be sure to find these out so that you know what’s available to you.

The Double Glazing Network is made up of many businesses which operate in various counties in the U.K. we’ve made it as easy as possible for you to find your local double glazing supplier to be able to request a quote from them to see how they stack up against the competition and we’re pretty confident that these businesses are competitively priced, meaning what they quote is industry standard to which you will struggle to find better offers out there.

For something such as a standard single double glazed replacement window, you may be expected to pay between £200 – £500. This is quite vague due to the amount of options there are.

Specification, style, size and other variables will increase the price for replacement windows and sometimes, you have to accept these price increases because of the style of your other windows.

If you have Georgian bars for all your other windows in your property, then you more than likely need to include Georgian bars in your new windows so they don’t look out of place.

Most manufacturers offer a 10 year guarantee on all their double glazed units as generally, this is the lifespan of units.

You may need to replace failing units in the meantime or if a quick and cheap double glazing fix is what you’re after, whilst this may fix the issues, long term you may run into more problems. Instead, look at comparing quotes for repair costs and replacement costs.

In retrospect, you may find you can afford to make these changes rather than a short term quick fix, such as a double glazed unit. It’s best to research and look around – with a budget in mind – to see if replacement windows is affordable to you.

The material of the frames is one of the most important factors when determining the price and is dependant on the material. There are three base materials in the U.K. to choose from – uPVC, wood and aluminium.

Each come with their own pros and cons, but for the consumer, the price is the most important consideration to make to see what you can afford, at the very least, most people will be able to afford uPVC and this will generally be the most popular choice anyway because of the stylish, contemporary design which improves the overall look and quality of the home.
