Installing uPVC frames

UPVC double glazing is the most popular choice for replacement windows in the UK.

However, if you’re investing in new windows for your home, you need to know that they are right for your home and your budget.

You need answers to questions like: How much do uPVC windows cost? How long do they last? What’s your potential payoff? Will they provide a return on your investment?

  • uPVC casement windows average at around £372-£961 each, according to the UK Federation of Master Builders.
  • Top window manufacturers like Everest and Anglian produce most of their uPVC double glazing right in the UK.
  • uPVC double glazing with an A++ energy rating can save you over £200 in annual energy costs.
  • A good uPVC window normally has a 10-year warranty, but it can last for 20+ years with proper maintenance.

Having the right information about uPVC window options can help you make the best decision for your home. We’ve put together a complete guide to answer all your questions about uPVC double glazing in the UK.

What’s in this guide?

uPVC Double Glazing Costs

Installing new windows is a major investment, but you can keep your costs reasonable with smart buying decisions. uPVC double glazing is the most affordable option: a typical casement window starts at around £371, going up to over £961. The following chart compares average costs per window type, based on a medium-sized uPVC frame.

WindowAverage Cost  
Casement £372 – £961
Sash £719 – £1,159
Tilt & Turn £589 – £713
Bay (3-Section)£1,364 – £1,674
Bow (3-Section)£1,426 – £1,674

uPVC window costs can vary a great deal depending on the manufacturer, installer and project complexity. Keep in mind that window fitting costs represent up to 60% of total replacement costs. This means you cannot get a 100% accurate quote until an installer inspects your home. Having covered the typical cost of uPVC windows, you’re probably wondering how long they will last.

How Long do uPVC Windows Last?

uPVC windows can last between 10 and 35 years depending on the manufacturer, installation quality and care. Unlike wood and composites, uPVC is very durable and resistant to rot and decay. The material is also easy to clean and maintain.

The lifespan of your uPVC windows depends on several factors:

Care – Smoke, dirt and water can build up on uPVC frames and discolour their surfaces over time. Window frames maintain their appearance when they are cleaned regularly.

Reinforcement – uPVC is durable, but susceptible to bowing and buckling over time, especially when supporting heavy glass. High-quality uPVC windows have reinforced corners to ensure a lifespan of 20 years or more.

Sealing – Good sealing is essential for the longevity of windows. When seals break, they allow moisture between the panes – this leads to fogging, misting or condensation. It is crucial that your window installer offers quality sealing, covered by a warranty to protect your investment.

uPVC Double Glazing Warranties

When you purchase uPVC double glazing, the warranty or guarantee terms vary depending on the installer. The best recommendation is shopping around, comparing your options, and having a clear picture of what you’re getting for the money. Large installers often have the best deals, since they can afford to offer better warranty terms with insurance backing.

Here are the warranty/guarantee terms offered by five leading window installers in the UK:

CompanyWarranty/Guarantee Terms
Everest10-year window parts and materials guarantee.
10-year or 20-year condensation and fogging guarantee depending on the product line, includes discolouration coverage for white uPVC frames.
Lifetime condensation and fogging guarantee available for an extra cost.
*Insurance-backed guarantee.
Anglian10-year parts and labour guarantee.
10-15-year guarantee for gas-filled windows.
*Insurance-backed guarantee.
First Home Improvements12-year window warranty.
*Insurance-backed warranty.
CR Smith10-year triple guarantee: parts, product and workmanship.
*Insurance-backed guarantee.
Evander10-year uPVC window warranty.
1-year repairs and workmanship warranty.
*Windows approved by the insurance industry.

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 offered by the company. Also keep in mind that many providers don’t have insurance-backed guarantees.

How Much Does Double Glazing Save on Energy Bills?

It is common knowledge that double glazing will reduces heating and cooling bills, but how much? And how long will it take you to pay them off? Double glazed glass and uPVC are both energy efficient materials with a high thermal resistance, which makes them ideal for reducing energy bills. To estimate how much you can save in a UK home, we use the following figures from the Energy Savings Trust, which were published in April 2016.

Property TypeDetachedSemi DetachedMid TerraceBungalowMid-floor Flat
A-Rated Double
Glazing Savings
£120-155£80-110£65-85£55-75£40-55

However, UK energy costs increased by 110% between 2016 and 2023. Annual energy costs for the average home increased from £1,236 to £2,592. Keep in mind this is caused by higher natural gas and electricity prices, not an increase in consumption. Since energy costs have doubled, we can assume the savings achieved by double glazing are also twice as high compared with 2016.

Type of PropertyDetachedSemi DetachedMid TerraceBungalowFlat
Number of Windows106654
Energy Savings per Year
A-Rated Double Glazing
£240-310£160-220£130-170£110-150£80-110
Estimated Cost (£450 per window)£4,500£2,700£2,700£2,250£1,800
Average Savings over 20 Years£5,500£3,800£3,000£2,600£1,900
Net Savings£1,000£1,100£300£350£100

The average home in the UK sports eight windows and you can calculate your average costs accordingly. If you choose mid-range uPVC casement windows, you can expect to pay around £3,200- £4,800 in total. In this same house, you can save over £240 per year if your current windows are already 20 years old. This means your new windows will most likely earn a return after 20 years, or at least they will break even. Considering that uPVC windows can last 25-35 years with proper care, you may see an even higher return.

Triple glazing offers higher savings but is also more expensive – in many cases, the increased savings do not make up for the additional cost.

Pros of uPVC Double Glazing

uPVC windows offer numerous benefits that make them an attractive investment for your home. As a frame material, uPVC offers several advantages:

  • More affordable that other materials like timber and aluminium.
  • More energy efficient than most other materials.
  • Resistant to airflow.
  • Durable.
  • Minimal maintenance needs.
  • Strong frames offer security.
  • Weather resistant.
  • Available in hundreds of colours and styles.
  • Recyclable.
  • Can last up to 35 years.

Cons of uPVC Double Glazing

Like any building material, uPVC also has technical limitations we must consider:

  • The frame must be reinforced.
  • Less durable than aluminium.
  • Less popular with homebuyers.
  • May discolour over time.

uPVC has more pros than cons overall, making it a cost-effective window material. However, you should still review your options and take the best decision for your home.

Comparing Window Costs: uPVC vs Timber vs Aluminium

Timber and aluminium windows are the most popular options after PVC. They are more expensive as you can see in the table below, but also more durable. This table compares the cost of casement windows, but you can expect a similar trend for other window types:

Material Cost per WindowLongevity
UPVC £372 – £96120-35 Years
Aluminium  £744 – £1,14720-50 Years
Timber£1,147-£1,82930+ Years

We recommend considering the value you are adding to your home, the style and age of your existing windows, and the overall style of your home. uPVC windows are recommended if you want to keep your budget low, while aluminium and timber are regarded as premium materials.

Getting the Lowest uPVC Double Glazing Quotes

uPVC double glazing is a cost-effective solution when you need a window replacement. Glazed window installation is a highly competitive market, and you can take advantage of this to negotiate a good price. Here are some buying tips:

  • Always compare quotes. If you get many quotes, you can rest assured that you are getting the best deal in the market.
  • Go into every sales meeting prepared. Get familiarized with the different window types, their cost and their features. If you know what you want and how much it should cost, you won’t be talked into paying 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 will only get an accurate price after the installer inspects your property to estimate window fitting costs.
  • 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. You should also ask the installer to break down any additional costs. Make sure you understand what the offer includes – are you being charged extra for travel or trash removal?
