Determining which double glazing company provides the best customer service often depends on individual clients’ experiences and expectations and can therefore be subjective.

Several double glazing companies have reputations for good customer service. These businesses, including Anglian, are often praised for their professional installation teams, responsive customer support and reliable aftercare. Remember that customer service quality can change over time, so it’s a good idea to look at the most recent customer reviews and ratings of the installers you’re considering as potential hires.

Discover how much installing new windows in your home might cost by answering a few quick questions.
When researching double glazing providers, you should ensure the ones you approach have a good reputation. Local business directories and listings provide basic business information about companies operating in specific regions and may provide customer testimonials. By browsing these reviews, you can gain insights into each provider’s reputation, customer service, product quality, warranty offerings and pricing and finance options. All are vital factors when considering which double glazing company to work with.
Friends, family members and neighbours willing to talk about their experiences with double glazing window companies can assist you with your search. Online reviews offer a broad perspective but might not always accurately represent a company’s service quality. Personal recommendations from people you know and trust can provide valuable and practical insights you may not find online.
For example, other people can share information on the level of disruption during installation, the work site cleanliness and the workers’ punctuality. Furthermore, they can tell you whether a particular company completed its projects on time and within the budget.
Your local DIY store can help you find reputable double glazing companies. Hardware suppliers often develop relationships with local service providers based on shared values of quality, reliability and customer satisfaction. These stores can be good sources of information about window installers.
Several members of the Independent Advisor team have first-hand experience finding double glazing companies and installing new windows in their homes. Here are some of their key tips and takeaways to help you choose the provider that best meets your needs.
For our house in a conservation area, we had to apply for planning permission to install replacement timber windows. Choosing a local supplier meant any amendments from the planning officers were quickly dealt with by a company that knew the regional styles and preferences. The company also offered a very competitive price for bespoke work and came with great recommendations from neighbours.
I chose Anglian Home Improvements to replace my kitchen window and swap my patio doors with French doors, as the company was offering remote appointments and had a good offer on its windows. The process was straightforward, with a technician coming out to measure up, followed by the installation. This was quick, with minimal disruption or mess left over afterwards. However, I had an issue with the door alignment allowing cold air to get in. Anglian fixed it free of charge. Overall, I’m very happy with Anglian. One small gripe is that Anglian only provided one key for the window, whereas Britannia provided multiple copies.
When choosing a double glazing provider, you should consider local companies as well as national brands.
Local installers are likely to have the same products as national providers but may be able to offer reduced wait times and lower travel fees because of their proximity. Some of the larger companies may not operate in your region if you live in a remote area. In that case, local companies might be your best option.
You should be able to find reputable local providers that can install bespoke and made-to-measure windows in various styles. They may even offer more materials, such as wood and aluminium, than some of the larger businesses. Your neighbours, friends and family members may have existing relationships with local double glazing companies and could offer you insights into these installers’ product quality and customer service levels.
There are several possible ways to contact these companies. Choose the one that works best for your convenience and comfort.
ADM Improvements has been installing double glazing across the South East for nearly 20 years. The company’s director, Antony Matthews, spoke to our experts.
Antony says the company is busier than ever, carrying out up to five installations daily. The same is true across the country, with his industry contacts also reporting uptakes in residential installations.
Many customers are choosing to target specific windows for replacement. Front-facing ones are particularly popular because customers save money by replacing only some of their windows while still improving their home’s appearance and energy efficiency. This means they can afford to explore different styles, such as sash or bay windows, or coloured options.
Antony also says that one of the benefits of choosing a local installer is that communication can be much more personal, and the customer feels an increased connection to the project. Often, the customer can contact the installer who carried out the work directly rather than dealing with a support desk. This resolves any questions or issues far quicker and improves the overall experience.
