Which double glazing company should you choose?

The decision to replace the doors or windows in your home, or to add a conservatory represents a major investment. You’ll have done your research in to the style you’re looking for and you’ll probably have a very good idea of what you want.

But how do you choose a double-glazing company to deliver these improvements to your home?

Independent vs National

The double-glazing market is highly competitive. Our customers all tell us that they carry out a lot of research in to what type of company to place their business with before making their choice. First up for consideration is whether to go with a local independent firm or a large-scale national brand.

The large-scale national “big brands” often come with hefty price tags and gimmicky sales tactics. Their sales representatives can reel off facts and figures and offer on-the-spot and time-limited discounts which can be very intimidating.

Unfortunately, these sales reps don’t always know the finer details about the products and never actually come in to contact with them, apart from the small samples that they will bring to your home. This is in stark contrast to most independent double-glazing firms who operate completely differently.

In a recent survey by Which? 83% of the 2,155 Which? members that they surveyed said they used an independent company to install their double glazing. Independents achieved an overall satisfaction rating of 84%, compared to only 54% for one big-brand name (source).

Formula One are proud to be an owner-managed business that has been serving the West Midlands and Shropshire regions since 1998 and 2005, respectively. Our locally based precision engineers have over 25 years’ experience in the industry and our fitters have been employed by us for over 10 years, working solely on Formula One products. They truly know our products inside out.

Our Group Commercial Manager, Dean Crowther offers a genuinely bespoke service to our customers. From meeting customers at our showroom or in their own homes and personally preparing all quotes, Dean ensures that each customer receives a comprehensive breakdown of the items that have been discussed and technical drawings of each component. He also specifies orders, surveys properties and manages each job from quotation through to completion. Dean’s knowledge of our products is unrivalled. He can help our customers to make informed decisions about their new windows, doors and conservatories and is always available to answer queries about our products.

Formula One customers tell us that this personal approach is a key factor that convinces them to bring their business to us, providing essential reassurance and guidance as they invest in their home improvements.

Another factor that we believe reassures our customers is our policy to avoid run tacky promotions. In contrast to the big-brand firms, we like to rely on our industry expertise and, crucially, word of mouth recommendations from past customers to sell our products. We might not always be able to offer the lowest price, but we can guarantee that we offer the best value for money.


Double glazing comes with a range of benefits, ranging from improved security, reduced condensation, keeping heat inside and keeping noise out. All these factors depend on the quality of the product that you’re buying.

At Formula One we pride ourselves on using only premium-quality products. Our windows are available as double or triple glazed and are complemented by superior quality seals, hardware and composites.

Our team combines the highest quality materials with meticulous attention to details to design and manufacture all our products in-house. This means that we can monitor every stage of the process from manufacture to installation and allows us to confidently offer a comprehensive guarantee.


When you buy double glazing products from Formula One, you can be sure that you are investing in a company that cares the security of your home and your family. All our products come with A-rated security features as standard, conforming to BS7412/PAS24 and ISO 9001.

However, if required by a customer, our products can be enhanced with further security features to meet the exacting standards of Secured by Design, an initiative backed by the UK Police Service.

Energy rating

As with electrical appliances, double glazing carries an energy rating that illustrates the energy performance of the unit. The British Fenestration Rating Council runs the double-glazing energy rating system. The highest rating possible is A++ and the lowest rating is E.

All Formula One windows are manufactured to an A rating. We also offer upgrades to A+ and A++.  This is far higher than building regulations, which state that new double glazing for housing should be a minimum rating of C.

At Formula One, we also have products that are endorsed by the Energy Saving Trust, an independent organisation committed to addressing the climate emergency. These products hold the highest A++ energy rating and will afford the highest energy saving for the household.


All Formula One products are fully protected by 10-year guarantees provided they have been properly installed, used and maintained. These comprehensive manufacturer’s warranties cover mechanical operations for 10 years and surface finishes on handles and door furniture for 1-10 years. Our PVCu profiles are also guaranteed for 10 years against discolouration, warping and cracking.

We hope that our confidence in our products is clear to see in our extensive guarantees – we aim to achieve 100% customer satisfaction and believe that with the Formula One Range™ this is possible.
