Founded in 1990 by John Valente, Coral began life at Perseverance Mill in Wibsey with a simple promise — put customers first and let service lead everything else.
“From a small Bradford workshop to one of Yorkshire’s most trusted names — our story is built on honesty, hard work and pride in every job.”
We’ve stayed proudly family-run, with John and the Valente family still hands-on today. That personal approach has helped us build lasting relationships with customers, suppliers and our own team — many of whom have been part of the Coral family for decades.
Putting people first has earned Coral recognition both locally and nationally.
We’re members of the Consumer Protection Association (CPA), winners of the 2024 CPA 20-Year Achievement Award, and accredited by Which? Trusted Traders and FENSA — giving every homeowner total confidence in our quality and service.
In 2025, The Independent named Coral Windows the Best Overall Double Glazing Company in the UK, praising our customer-friendly payment options, strong guarantees, and consistently excellent reviews — another proud moment that reflects our long-standing focus on quality and care.
Supported by recognised accreditations and Environment Agency guidance, we deliver home improvements you can trust to meet high environmental and regulatory standards.
FENSA is one of — if not the most — recognisable accreditations in our industry. They ensure that all qualifying installations, whether a single window or a full house of windows and doors, comply with building regulations. If your installation is covered by FENSA, you will automatically receive your certificate directly from FENSA within a few weeks of completion.
Checkatrade only showcases the very best installers across the United Kingdom — you won’t find subpar businesses displaying their logo. Even better, with hundreds of reviews, we at Coral are proud to maintain a near-perfect score for our performance throughout the installation process.
One of the UK’s most respected vetting organisations, Which? has decades of experience assessing products and businesses. We’re proud to be recognised as a Which? Trusted Trader, demonstrating our commitment to excellent customer service and professional installations.
Here at Coral, several of our products are supported by the BSI Kitemark. It serves as symbol for safe and reliable products. To see it on our site assures you that our double glazed home improvement products are consistently of the very highest quality.
By working with a CPA approved business, your investment is protected. In the incredibly unlikely instance that something prevents Coral from repairing your double glazing, you aren’t out of pocket. You can have complete peace of mind when you renovate with us.
Here at Coral, we are proud to be TrustMark accredited. As the UK Government-endorsed quality scheme, it’s a sign that our work meets strict standards for workmanship, reliability, and customer care. Seeing the TrustMark logo on our site gives you confidence that your home improvement project is in safe and trusted hands.
Keeping manufacturing here in Bradford means we’re always close to the craft.
We continually invest in new technology, better materials, and ongoing training for our fabricators — making sure every job is done right, first time.
Our commitment to improvement was recognised at the 2024 Bradford Means Business Awards, where we proudly received the Innovation Award — a huge moment for a company that started with a handful of staff and a big idea.
More than 35 years on, Coral is still here in Yorkshire — designing, making and fitting uPVC windows, doors, conservatories and extensions for generations of homeowners.
Our promise hasn’t changed since day one:
Look after people, keep improving, and do the job properly.
Pop into Coral Mill on Halifax Road or one of our five Yorkshire showrooms — have a brew, try the products, and meet the team who’ll look after your home like it’s their own.
