Updated: 7 July 2026

As of 6 July 2026, Primrox.co.uk is proudly owned and operated by Ada Windows Ltd.

This marks the beginning of an exciting new chapter for Primrox—one built on experience, long-term investment and a genuine commitment to helping homeowners find high-quality windows, doors and glazing products with confidence.

For anyone who has visited Primrox before, we'd like to extend a warm welcome. While the ownership has changed, our ambition is simple: to build on what Primrox has already achieved and develop it into one of the UK's most trusted online destinations for windows, doors and home improvement products.

Behind Primrox is now a company with decades of experience in the glazing industry, and we're looking forward to bringing that knowledge, together with an expanding product range and helpful advice, to customers across the UK.

Introducing Ada Windows Ltd

Primrox is now part of the Ada Windows family.

Ada Windows Ltd is a family-run manufacturer and installer specialising in high-quality, energy-efficient windows and doors. With management experience in the glazing industry dating back to 2001, we've spent many years helping homeowners improve the comfort, appearance, security and energy efficiency of their homes.

Our approach has always been straightforward.

We believe customers deserve honest advice, quality products, skilled workmanship and clear communication from beginning to end. Those values have helped us build long-lasting relationships with homeowners, and they're the same values we'll bring to Primrox.

Why Ada Windows Chose Primrox

When we looked at Primrox, we didn't simply see another website.

We saw a brand with potential.

Primrox already had a recognised identity and an opportunity to become a valuable resource for homeowners researching replacement windows, front doors, aluminium glazing and modern home improvement products.

Rather than replacing what existed, our aim is to strengthen it.

We'll continue investing in the website, improving the customer experience and expanding the information available so visitors can make informed decisions before purchasing.

For us, this isn't a short-term project.

It's a long-term commitment.

What This Means for Existing Customers

If you've previously discovered Primrox through an online search, you can continue using the website with confidence.

The change in ownership means that Primrox now benefits from the experience, knowledge and resources of Ada Windows Ltd.

Our commitment is to provide:

High-quality windows and doors
Clear, helpful product information
Friendly customer support
Reliable service
Continuous improvements across the website
A growing range of products for every style of home

Our goal is to earn your trust—not just for one purchase, but whenever you need advice or products for future home improvements.

One of the biggest changes you'll see over the coming months is a significant expansion of the Primrox product collection.

Why Quality Windows and Doors Matter

Replacing windows and doors is one of the most valuable improvements you can make to your home.

Modern glazing can help improve:

Energy efficiency
Thermal insulation
Home security
Noise reduction
Kerb appeal
Natural light
Property value
Everyday comfort

Choosing the right products is important, but choosing the right company is equally important.

That's why Ada Windows focuses on providing products that combine attractive designs with dependable performance and professional installation.

Built on Experience Since 2001

Experience makes a difference.

The glazing industry continues to evolve, with improvements in energy efficiency, security, manufacturing techniques and product design.

Having worked within the industry since 2001, we've seen these changes first-hand.

That experience helps us understand what homeowners really want:

Products that perform well.
Honest recommendations.
Fair pricing.
Reliable installation.
Long-term peace of mind.

Those principles will continue shaping both Ada Windows and Primrox.

A Commitment to Quality

Quality isn't something that's achieved through a single product.

It's reflected throughout the entire customer experience.

At Ada Windows, we're proud to offer:

Energy-efficient window and door systems
Skilled installation teams
A 10-year insurance-backed guarantee
FENSA registration
TrustMark registration
Modern manufacturing standards
Friendly customer service
Professional aftercare

Every improvement we make to Primrox will reflect those same standards.

Looking Beyond Products

While expanding our range is an important part of our plans, we also want Primrox to become a genuinely useful resource.

Over time we'll continue publishing guides covering topics such as:

Choosing between uPVC and aluminium windows
Understanding energy ratings
Improving home security
Selecting the right front door
Planning home renovations
Window styles for different property types
Glazing terminology explained
Maintaining modern windows and doors

Buying new windows isn't something most homeowners do every year.

We believe customers should have access to straightforward, trustworthy information before making that investment.

Building Long-Term Relationships

Our ambitions extend well beyond selling products.

We want customers to return because they know they'll receive honest advice, dependable service and products they can trust.

Long-term relationships are built through consistency.

By answering questions clearly.

By standing behind our work.

By continuing to improve.

And by treating every customer with the same care we'd expect ourselves.

Those values have helped Ada Windows grow, and they'll continue guiding the future of Primrox.

Looking Ahead

This is only the beginning.

Over the coming months and years, you'll see continued investment throughout Primrox.

That includes:

A wider product selection
Better buying guides
More inspiration for homeowners
Improved product information
Helpful comparison articles
Easier website navigation
Ongoing improvements to customer support

Every update is intended to make Primrox a better place for homeowners researching windows, doors and glazing products.

We're excited about what's ahead and look forward to sharing that journey with you.
