Double glazing prices are going to be your first consideration when installing or replacing your windows.

Right?

You might be worried about the excessively high double glazing prices, or how to go about finding the right rates.

The good news is:

The market for double glazing is extremely competitive, and if you go about it the right way, you can end up with high-quality windows at an affordable price! So how is the best way to find double glazing prices that are within your budget? Let’s find out.

What are The Factors that Affect Double Glazing Prices?

Let’s face it:

As with any other product, the double glazing prices will vary according to different factors. What are these factors?

How Does The Material of Window Frames Affect Double Glazing Prices?

Double glazing prices for windows are hugely dependant on the material of the frames. In the UK, you have the option of three frame materials, namely uPVC, wood, and aluminium.

Each of them have their own sets of advantages and disadvantages, but if your only consideration is double glazing prices, then uPVC might be your best option. Typically, wood and aluminium frames cost 30% to 50% more than uPVC. This translates into a huge difference in double glazing prices.


Double Glazing Prices For Windows


Does The Number of Windows Affect Double Glazing Prices?

Double glazing prices vary dramatically depending on whether you are replacing all old windows, or simply replacing a limited number of damaged windows.

Does The Size of Windows Change Double Glazing Prices?

If you are looking for double glazing prices to replace all your windows, you might also have to take into account factors like the size of your windows. Small windows like a bathroom window might cost you around £150, while a regular 1800mm x 1200mm window could cost £350.

How Does The Size and Location of House Influence Double Glazing Prices?

Believe it or not, the size and location of your house can affect double glazing prices!

How?

The larger the house, the more windows it will have. If your house is not on the ground floor, double glazing prices will also include setting up a scaffolding.


Window Styles Affect Double Glazing Prices


Does The Style of Windows Impact Double Glazing Prices?

The style of the windows also determines the double glazing prices for your house. Double glazing prices for casement windows are significantly lower than double glazing prices for, say, sash windows.

For example, double glazing prices for a uPVC casement window measuring 60cm x 90 cm can start from around £250. For the same size and material, the double glazing prices for a sash window might start around £500.

How Do Energy Efficiency Requirements Affect Double Glazing Prices?

Double glazing prices are also affected by the quality and energy efficiency ratings you might require. Double glazing rates for windows of rating A or A++ will obviously be more expensive than those with a rating of B or C.


Fittings Affect Double Glazing Prices


Do Add-ons and Design Features Add To The Double Glazing Prices?

Costs of Add-ons and design choices add up, making your double glazing prices go up. Design choices like the type of frame, handle designs, bespoke finishes, extra security measures, and pet flaps can all end up adding up in your double glazing prices.

What Bearing Does Glass Style Have On Double Glazing Prices?

Design features on the glass may increase your double glazing prices by £30 per unit, or more.

Does Toughened Glass Mean Higher Double Glazing Prices?

Sealed units that go into frames that are 800mm or lower from the floor require toughened glass.

In case of the glass breaking, toughened glass does not break into shards, which might be dangerous. It breaks into more or less harmless crystals that are not likely to hurt you. This safety feature means you pay extra for toughened glass, adding to your double glazing price.

What Are The Double Glazing Prices You Might Expect To Replace A Window?

As we mentioned before, the double glazing prices vary according to a number of variables. They might even change from company to company, installer to installer.

You might get a small company run by a single repairman who will replace one sealed glass unit for around £75. On the other hand, you might want a large specialist company that does it for £50 a piece.

Why this difference?

Double glazing prices per unit may change according to the supplier’s buying power, business size, and overheads. It may also vary according to their level of expertise and quality assurance.

Should You Repair Or Replace A Damaged Window?

While it may be tempting to spend a lesser amount and simply repair a broken window, it might not prove to be the best solution in every situation. In some cases, it might be better to invest in a new installation so that the overall performance of your house does not suffer.

However, if a proper assessment shows that a simple repair might be enough, by all means, go for it!

Just bear in mind, that the money you are investing needs to improve the efficiency and performance of the house as a whole. If the double glazing prices are within your budget, you might get better value for money for your property.

Should You Include Energy Efficiency in Your Double Glazing Prices?


Energy Efficiency

It might seem easier to save money on your window installation by foregoing energy efficiency.

However:

The money you save in energy efficiency and the amount of energy you use in your household ends up adding up.

Even properties with an energy efficiency rating of C can see a saving of £50-175 a year, simply by replacing single glazed units with double glazing.

In the long run, energy efficiency investment in your double glazing prices means bigger savings for you in the future!

How Do You Ensure the Most Competitive Rates for Your Double Glazing Needs?

It does sound tempting to go for the lowest double glazing prices that you can find. However, lowest does not always mean the best bargain. Buying from a disreputable supplier or installer might mean you end up losing money because of a poor quality product.

Worst case scenario, you may even be scammed and lose money with no windows to show for it. You may go for cheap installations but end up paying more in energy consumption.

In order to get the best value, you need to find the balance between double glazing prices and the quality of the product and services. You want good quality windows, but don’t want to pay exorbitantly high double glazing prices.


Double Glazing Cost


Double Glazing Prices Process

You have decided to go for a complete overhaul of your window glazing and are now looking for double glazing prices. How can you ensure you get the best possible price?

Simple! Just use our tips to get good double glazing prices, complete with quality assurance!

1) Always Compare

Never go with the first price quote you get. Always get double glazing prices from multiple suppliers and installation companies.

You will be amazed at the price difference you will see across different businesses.

Additionally, you can get lower double glazing prices by asking for a discount for multiple windows.

2) Negotiate Prices with the Salesmen

Salespeople tend to quote a higher rate the first time around. If you negotiate the rates with them, you might find yourself with a double glazing price quote that is much lower than the original quote.  All you need to do is ask!

3) Find Reputed Installers

Installers who are registered with FENSA or the GGF come with an inherent advantage.

What’s that?

They are more likely to uphold themselves to higher standards and are less likely to be fraudulent. You will lose more money with fraudulent services than you will save on your double glazing prices.

4) Be Sure of What You Want

You may rush into buying a style of windows that you end up hating once they are installed simply because the double glazing prices for them were irresistible.

Now, you’re stuck with windows you don’t like, and will end up costing you more to replace.

Take the time to find the right style and pay for it instead of rushing into a decision you will regret later, simply because it was cheaper.

5) Consider The Frame Material Carefully

uPVC, wood, and aluminium have different prices. Consider why you want one over the other carefully. If it’s just appearance, you can get frames that mimic the appearance of other materials. You can get a wood finish in uPVC. Don’t pay more for something that is just cosmetic!

6) Don’t be Pressured

No honest company will ever force you into rushing into a decision. If you are paying the high double glazing prices, you have the right to take your time to decide what you want.

A company that pressures you into making snap decisions might not have your best interest at heart.

7) Shop During Quiet Times

You are more likely to get better double glazing prices if you shop around at a time when it’s not ‘peak season’ for windows installation.

When is it a good time to get low double glazing prices?

For the most part, December is considered a slow time. If you go shopping for double glazing prices at this time of the year, you might find rates that are lower than the rest of the year.

What Are the Double Glazing Prices for a 3-Bed Semi

Are you looking for double glazing prices for your 3-bed semi?

Again, there are various considerations that go into making up the double glazing prices for your house. The number of windows, window style, and the energy efficiency you are looking for will all affect the double glazing price.

That is not even factoring in the rates of the frame material you want! However, a rough estimate of double glazing prices for a 3-bed semi would be between £3000 to £5000.

This estimate is bound to vary according to the glazing quality you require, the supplier you go with, and whether or not you are opting for installation.
