One single uPVC casement window at 60cm by 90cm will cost £250 on average, yet a sash window in the same size and material will start at upwards of £500

There are lots of factors to consider that will affect and start to increase your double glazing prices when you go to receive your quotes.

Is Double Glazing Becoming More Expensive?

The current global situation has caused disruption to all aspects of daily life across different industries around the world, and the double glazing sector is no exception.

Increased Homeowner Demand for Double Glazing

This increased demand from homeowners leads to more pressure on manufacturers to provide uPVC windows with double glazing than ever before. A further issue caused by the pandemic was rising double glazing manufacturing cost, with raw materials and base ingredients to manufacture the desired products getting more expensive.

The soaring popularity of double glazing, coupled with the relative scarcity of materials for manufacture, has seen double glazing prices increase in line with and even beyond the rising interest levels. As such, many manufacturers have raised their double glazed window prices significantly to account for this, and while installers will often try to provide the best price for double glazing, the cost is impacted by these changes through the supply chain.

Sash windows are well suited to period properties. They are also a good choice for homeowners wanting a more traditional style but don’t want to pay high double glazed window prices.

Average Double Glazing Prices For A House

Double glazing costs between £3,000 and £5,000 for a whole house.

As double glazing prices vary between the size of the individual windows, they will also fluctuate based on the size of your property.

It’s therefore important to understand what the average price of double glazing a house is, so you can identify how your specific circumstances and specifications will affect your double glazed window prices.

How To Keep Double Glazing Prices Low

When choosing new windows for your home, there are lots of important decisions to make to keep the double glazing cost low. The cost of double glazing can be offset by the investment they are for your property, not only financially but psychologically too. Key components of windows that make them more desirable to homeowners though potentially more costly as well include energy rating and locking systems. 

The energy efficiency of your windows will increase the double glazing prices you are quoted. That’s because thermally efficient windows that meet higher energy ratings will have a higher double glazing cost due to the elements involved in their manufacture. With less use of your heating, your bills will stay low. 

Similarly, double glazing prices will increase if you choose additional high security hardware. The latest locking mechanisms will be more costly and drive up your double glazed window prices. But if the safety of your home and loved ones is a major concern for you, the higher double glazing cost will be worthwhile. Comparing double glazing prices isn’t about finding the cheapest option – it’s about understanding what to prioritise for you, your family and your property.

How Will Accessories & Hardware Affect The Price?

A window’s size and style play a huge part in how much double glazing costs, and to an extent, these are factors that are out of your control if you need to replace a single matching window among many. But one of the primary decisions you can make is what kind of accessories will you choose? Other customisation options include any glass or glazing designs, as well as certain colours or finishes for the frame.

Here are some popular questions homeowners will consider when designing their new windows:

  • Do I want a gold or chrome handle?
  • Will I choose a woodgrain foil or finish?
  • Should the glass feature a pattern or design?

If you’re asking these or similar questions and the answer would be yes, then you can expect your windows’ double glazing prices to increase. Other options include security mechanisms mentioned above, as well as toughened glass and certain handle styles as well as finishes. Any of these choices beyond standard white uPVC frames will see double glazing costs rise.

For these options or similar, you can expect to add around 20% to your estimated double glazing price. This is not to say that you shouldn’t design your new windows exactly the way you want – it is simply important to remember that these will affect how much double glazing costs and you can factor these important decisions into your estimated quotes.

How To Find The Best Double Glazing Prices

If keeping your double glazing cost as low as possible is a priority, the material of the window frame will play a significant role in this. uPVC windows are the most cost-effective option. You’ll enjoy cheaper double glazed window prices around 30% to 50% lower than timber or aluminium window frames.

However, you may feel committed to a particular shape or style of window to suit your property. That’s where there may be less manoeuvrability in how you can control double glazing prices for your property. If you want to retain your home’s authentic style, wooden windows may be the best choice, but they have a higher double glazing cost.

Whichever window style you’re looking for, be it for a single window or multiple, you can compare double glazing prices near you from local installers. That way, you shouldn’t have to compromise on what type of window you want and how many you need. Comparing the double glazing cost is the best way to understand the market and save money.

This factor may help you to decide which is the best choice for you if it suits your budget. uPVC windows are the most cost-effective option compared to aluminium or timber. Within this, the style you choose will have an effect on the price range too.

The classic style of casement windows makes them ideal for most properties, with their reliable and functional opening mechanism.

The Best Window Frames

In addition to choosing your window style, you will want to consider the best frame. Again, the term ‘best’ will be weighted towards that which is right for you, rather than a universal answer that applies to everyone – as every home is different.

Also, similarly to the style, the material of the window frame you choose will affect the double glazing prices you receive from your comparison quotes. The most common options include uPVC, timber and aluminium. There are many advantages to each of these, from the versatility of uPVC windows to the traditional design of timber and the sleek aesthetic of aluminium. One factor affecting both the style and performance of the window frames is their thickness, which can vary from 14mm to 28mm depending on its size and shape.

Timber and aluminium frames cost around 30% to 50% more than uPVC windows on average. This makes a significant difference to how much double glazing costs for you. As such, that’s why the best material will depend not only on your preferences but how much this affects your double glazed window prices.

What Other Factors Affect the Price of Double Glazing?

The cost of replacing windows in the UK is affected by multiple factors. Some of these are in your control, such as which style and material you want, or how many you are choosing to replace in one investment. Others, however, are external factors that will influence your double glazing price.

Researching the home improvement market will make you more aware of how much double glazing costs. It will also give you an idea of the different products that companies offer and the double glazing cost differences, as not all uPVC windows are the same.

Local vs National Double Glazing Installers

Are local or national installers cheaper when it comes to double glazing prices? There is no definitive answer to this question and it will vary on a case by case basis. You will need to compare double glazing costs online from both local and national companies to find the best value for money.

Different companies will be able to provide varying warranties and guarantees for their products. These will depend on the profiles themselves. Similarly, some installers can offer flexible finance options to reduce the initial double glazing cost. This means you may be able to get your replacement windows more easily, so you can start saving money even sooner.

No matter which company you choose and how cheap or expensive their double glazing prices are, you should receive the same exceptional levels of customer service across the board. As well as comparing double glazing cost, look at the installers’ reviews. This will be a useful way to gauge their reputation and if this is a company you would like to work with. For many people, the service and interaction they receive are as important as the double glazed window prices, since this ensures a straightforward and stress-free installation.

Why Should You Compare Double Glazing Prices?

Taking a look at the whole market will give you a comprehensive overview of how much double glazing costs, and to what extent you can keep this as low as possible, while still choosing the window you want for your home.

Compare installers to identify the options they have available and if these are right for you. Some companies may not be able to provide the window style you need in your chosen material, and there will be significant variations between double glazed window prices among installers in your local area. Taking a broad overview of double glazing prices is the quickest, easiest and most effective way to find the best value windows near you.

At the cheaper end of the scale, you will more often find those with lower ratings. This means you won’t be able to save as much on your bills later on. A larger initial double glazing price makes a better investment in the long run, getting you windows with a higher rating to help more with energy saving options.

Enhanced Security

In addition to the latest locking mechanisms, modern windows are available with a wide range of glass options. For new windows, or to replace existing windows, you may want to consider toughened glass. If your window frame is 800mm or less from the floor, then your glass will need to be toughened, although this will increase your double glazing cost. This is manufactured by heating glass to a very high temperature, which is then cooled at a predetermined rate, making it 5 times as strong as ordinary glass to make sure it doesn’t break, and if it does, it breaks into smaller, less harmful, crystalised pieces. Choosing toughened glass can increase your double glazing cost by around 20%.

Range of Colours

Maybe you’re looking for current on-trend shades like Anthracite Grey or Jet Black, or perhaps you want to make a splash with vibrant shades or red and green. This choice can be down to personal preference, if you would like to reinvent your home, or you may need a particular authentic finish to suit your existing aesthetic. Whatever the reason, you can expect this to cause your double glazing price to increase.

What Is The Cost of Repairing Double Glazed Windows?

If you’re looking to replace a broken, outdated or underperforming double glazed window, you will want to compare double glazed unit prices. Comparing companies if the best way to do this, as each will have their own price list. On average, a single standard replacement window with double glazing will cost between £150 and £500. This initial estimate will take into account the factors we have discussed.

New windows should last for 10 years or more, but replacing them when they are faulty can be a temporary solution at best, costing you more in the long term.

Repairing double glazed windows can be an excellent investment if you don’t want to replace all your windows, then you could look to repair them only when you encounter problems. However, this reactionary response means you may be caught unawares and unprepared should your windows fail. Compared to the uncertainty and potential stress, replacing your windows at the time you want is a sensible choice, allowing you to take the time to shop around and find the best double glazing prices online.

When Should You Replace Your Double Glazing?

Double glazing units tend to have a life span of up to 20 years. Around the 15-20 year mark is where you might want to consider looking into window replacement costs. Lots of suppliers will offer a warranty. This can vary in length, so it is a good idea to ask about the warranties on offer.

One of the benefits of double glazed windows is that they are low maintenance. During the lifespan of your windows, maintenance tasks should be minimal.

Usually, just cleaning your new windows regularly should be enough to keep them looking good and in optimum condition. With a longer lifespan, double glazed window prices are even more worthwhile over time.

What Are The Alternatives?

Before or after you receive your double glazing prices, you may want to consider the alternatives. Perhaps this isn’t the right solution for your home, or your double glazed window prices are higher than you had initially thought. Understandably, you’ll want to look at all options before you commit to paying a high double glazing cost.

Double glazing may not be the right choice if you have a heritage property or even a listed building, in which case this type of improvement may not be permitted. In these cases, you might need to retain the existing windows. Alternatively, you may have heard that triple glazing is available and you are considering how the cost of this compares to the double glazing prices you’ve been quoted.

We’ll take you through the alternatives so you can understand the right investment for you and your home.

Double Glazing vs Triple Glazing

Many homeowners will look at the features, benefits and potential drawbacks of triple glazing in comparison to double glazing when looking to improve their homes. There are positives to both, and once again there is no definite answer on which is necessarily better for you.

With certainty, triple glazing is higher than the average double glazing cost. Prices are higher due to the additional pane of glass, and they are most expensive to manufacture as an extra chamber needs to be filled with argon gas. However, the advantages of this include improved noise reduction and thermal efficiency. For some, the higher cost will be offset by the benefits they provide, but you may not need these features unless you live near a particularly busy road or maybe even under a flight path.

Double Glazing vs Secondary Glazing

If you own a period property, you may not want to replace your existing windows with brand new frames. As sleek and stylish as aluminium windows are, they may not be the right fit for every home. To take this even further, if you live in a listed building, double glazing may not even be an option as you will have to retain the property’s original windows. That’s where secondary glazing becomes an option.

Secondary glazing is an additional glazed panel installed on the inside of an existing window. It provides similar advantages to double glazing without replacing or even affecting the original installation. As well as being the only choice in many cases for homeowners in listed buildings, it’s also popular as a more cost-effective option if you feel that the double glazing prices you’ve been quoted are too high.

Looking to enhance the performance of your home to an even greater extent? Outdated windows can cause sub-par thermal efficiency and security, and the same issues occur within older doors. That’s why you may want to replace your double glazed doors at the same time or soon after you replace your existing windows to enjoy total peace of mind.

The same factors that affect double glazing prices for windows will influence how much your new doors cost. With size, style and glazing to consider, the double glazing coswill vary accordingly. For example, uPVC is once again the most cost-effective option when it comes to doors as well as windows, while other options like composite and aluminium are at a higher cost.
