Getting the right information can help you to make the best decision for your needs. We’ve put together this complete UK guide to help you answer all your questions about PVC double glazing.

uPVC Double Glazing Costs

Installing new windows is a huge investment for your home, but that doesn’t mean you shouldn’t keep costs as low as possible. UPVC double glazing is the cheapest frame option, and therefore is typically the most cost effective solution for replacement windows. You can expect an average casement window to start out at around £250 and go up to over £500.

The following chart includes the average costs per window based on a medium sized frame.

WindowAverage Cost  
Casement £250 – £570
Sash £500 – £1,050
Tilt & Turn £400 – £675
Turn Dial  £400+
Bay £1,000+

In most cases, uPVC costs vary a great deal depending on the manufacturer, installer, and the difficulty of the installation. Because as much as 60% of total replacement costs relate to actual fitting, you cannot get a 100% accurate quote for your windows until the installer inspects your home. The chart includes average costs to have the frame fitted.

Now that you know how much your windows will likely cost, you’re probably wondering how long they will last.

How Long do uPVC Windows Last?

uPVC windows last between 10 and 35 years depending on the manufacturer, the care, and the quality of the original installation. Unlike wood and composite, uPVC is very durable, resistant to rot and decay, and easy to clean and maintain.

The longevity of your PVCu windows depends on several factors:

Care – Smoke, dirt, and water can build up on the surface of your uPVC glazing and discolour the surface over time. You will have to occasionally clean the frames to maintain their appearance.

Reinforcement – uPVC is a durable material but it is susceptible to bowing and buckling over time, especially when supporting heavy glass. Good uPVC windows include reinforced corners to ensure that they last for 20 or more years.

Sealing – Good sealing is essential to ensuring the longevity of windows. When seals break, they allow moisture and air in between the panes, creating fogging, misting, or condensation. It is crucial that your installer offer quality sealing and a warranty or guarantee to protect your investment in case something goes wrong.

Warranties on uPVC Double Glazing

Different installers offer different types of warranties and guarantees on PVC double glazing. For this reason, it is important to shop around, compare your options, and consider what you’re getting for the money. In this case, large installers almost always offer a better deal, because they can afford better guarantees with insurance to ensure that your guarantee is fulfilled no matter what.

Most guarantees ensure that your windows are covered for a minimum of 10 years – but some installers offer longer warranties. Many consumers choose local installers who typically offer lower prices, but you will have to inquire individually about the guarantee or warranty offered by the company. Most also do not include insurance.

How much can uPVC double glazing save you in that time?

Will I See a Return with uPVC Double Glazing?

Almost everyone knows that double glazing will reduce your heating and cooling bills, but how much? And how long will it take you to pay them off? UPVC is an energy efficient material with high thermal efficiency, making it ideal for reducing energy bills. We’ve put together a chart so you can see an estimate of how much you could save. However, these estimates are approximate, your actual savings will vary based on your home, your existing windows, and your energy usage.

Assuming you are installing uPVC double glazing, you can expect the following costs and returns over 20 years as estimated by the Energy Savings Trust.

Energy rating Detached (10+ windows)Semi detached (6+ windows)Mid terrace (6+ windows)Bungalow (5+ windows) Flat (4+ windows)
Savings per Year (A Rated)£130 – £175 £90 – £120 £80 – £105 £60 – £80 £50 – £65
Average Cost to Install (mid-range)£3,500 £2,100 £2,100 £1,250 £1200  
Savings over 20 Years  £3,500 £2,400 £2,100  £1,600 £1,300
Return  £0£300£0£350 £100

 

The average home in the UK sports 8 windows and you can calculate your average costs accordingly. For example, if you choose mid-range uPVC casement windows, you can expect to pay an average of about £2,400- £3,200 for 8 uPVC windows. In this same house, you can expect an average of £120 – £175 per year in savings if your current windows are already 20 years old. This means that your new doors and windows will likely break even or earn a return after 20 years. Because uPVC windows can last 25 and even 35 years with proper care, you may see a higher return as well.

Triple glazing costs more but offers a higher return – however, the increased savings do not typically make up for the additional cost.

Pros of uPVC Double Glazing

Overall, uPVC has more pros than cons, making it a quality material choice for most. However, you should still review your options and make the best decision for your home.

uPVC vs Wood vs Aluminium Windows

Wood or timber and aluminium windows are the most popular options after PVC, and you should consider them.

Material  Cost  Longevity
UPVC £250-570 20-35 Years
Aluminium  £500-605 20-50 Years
Wood  £845 – £910 30+ Years

In most cases, your primary concerns should be the value you are adding to your home, the style of the existing windows, the age of the windows, and the type of windows you want to install. Your current budget should be a concern as well.

Getting the Lowest uPVC Double Glazing Quotes

uPVC double glazing is a cost-effective replacement window solution. However, you can reduce costs further by working to get a good deal on installation and on the windows. Glazed window installation is a highly competitive field and you can leverage that to save money.

  • Always compare quotes. The more quotes you see, the more you can ensure that you are getting a good deal.
  • Go into every sales meeting prepared. If you know what you want, what it should cost, and why you want it – you won’t be talked into paying more for something you don’t need, or worse, paying more than your replacement windows are worth.
  • Get a full inspection before signing a contract. You won’t know the total price until the installer sees how much work fitting will be.
  • Check what you get for the money. If one installer offers a better warranty or more services for the same quote, they are the better offer. Similarly, check what costs extra. Are you being charged over the quote for travel or trash removal? Make sure you understand what the quote includes.
