By answering a few quick questions, you can get an idea of how much installing new windows in your home might cost.
If you’re considering a particular double glazing provider, you should check that the company has a good reputation. Look at local business directories and listings, as they may have customer testimonials and basic information about companies operating in specific regions. Such reviews can provide vital factors to consider, including each provider’s reputation, pricing, finance options, product quality, customer service and warranty offerings.
Friends, family members and neighbours might be able to tell you about their experiences with double glazing window companies. Although online reviews offer a broader perspective, their information may not be entirely accurate. To learn more about the quality of a company’s services, ask for personal recommendations, as they often provide more valuable insights.
People you know are more likely to provide details about what to expect during an installation. They can tell you about their experiences with the level of disruption, the punctuality of the workers and the cleanliness of the work site. They can also tell you whether a specific company stuck to the budget and completed its project on time.
Local DIY stores can help you find reputable double glazing companies. Hardware suppliers and local service providers often share values regarding quality, reliability and customer satisfaction. As a result, they develop a professional relationship, so DIY stores can be good sources of information about window installers.
Several members of the Independent Advisor team have experience of looking for double glazing companies and having new windows installed in their homes. To help you choose the provider that best meets your needs, here are some of our key tips.
We had to apply for planning permission to install replacement timber windows, as our house is in a conservation area. Our local supplier knew the preferred style for the region, allowing the installer to deal quickly with any amendments from the planning officers. The company also offered a very competitive price for bespoke work and had great recommendations from our neighbours.
When replacing my kitchen window and swapping my patio doors for French doors, I chose Anglian Home Improvements, as the company provided remote appointments and had a good offer on its windows. The process was straightforward: a technician came out to measure my windows, and the installation quickly followed. There was minimal disruption and little mess afterwards. When I had an issue with the door alignment allowing cold air in, Anglian fixed it free of charge. Overall, I’m very happy with Anglian. My one small gripe is that I was only given one key for the window, whereas Britannia provides multiple copies.
When searching for a double glazing provider, remember to consider local companies as well as national ones.
Local installers will often have the same products as national providers, and you could save money on travel fees. Since they don’t have far to travel, you might not have to wait as long. Also, some of the larger companies may not operate in remote areas, so if you live in such a region, local companies could be your best option.
Any reputable local provider should still be able to provide various styles of bespoke and made-to-measure windows. Local companies may even have a wider range of materials, such as wood and aluminium, than some of the bigger businesses. Also, your neighbours, friends and family members are more likely to have experience with local double glazing companies, so they may be able to provide valuable insights into their product quality and customer service.
With several ways to contact these companies, you can choose the one that works best for you.
For nearly 20 years, ADM Improvements has been installing double glazing across the South East. The company’s director, Antony Matthews, spoke to our experts.
Antony says the company is busier than ever and is carrying out up to five installations per day. This trend holds true across the country, and his industry contacts also report an increase in residential installations.
Many customers are only replacing specific windows, usually the front-facing ones. This approach allows them to save money and still improve their home’s energy efficiency and appearance. By replacing only a few windows, they can afford to opt for coloured options or explore different styles, such as sash or bay windows.
Choosing a local installer brings the benefit of more personalised communication. Rather than dealing with a support desk, the customer can often contact the installer directly, which makes them feel more involved in the project. As a result, any questions or issues are resolved much quicker, improving the overall experience.

Contact a double glazing company if your old windows are draughty, letting in leaks or noise, and get energy efficient replacements. Plan the installation to minimise disruption and check for government grants to potentially save on costs.
Installing new windows is complex and requires technical skills, so it’s best to hire professionals. They offer expertise, quality assurance with guarantees, compliance with building regulations, specialised equipment, and are trained in safety procedures.

uPVC double glazing windows can last an average of between 20 and 25 years, aluminium up to 30, and timber 50 years or more. However, you can extend this with proper maintenance, such as regular cleaning and checking for any signs of wear. If a company offers a long warranty, it’s typically an indication of its confidence in its products.
