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.
Federation of Master Builder
The Master Builder scheme is one that has been running for nearly eight decades, meaning they know a thing or two about home improvement. We comfortably exceed their recommended standards of quality and service, meaning you can place your complete trust in us.
FENSA is one of, if not the most recognisable accreditations in our industry. They ensure that all our qualifying installations, be it a single window or a full house of windows and doors, adhere to building regulations. Make sure to request a FENSA certificate post-installation.
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*.
*Insurance backed guarantees are issued with any contracts which require FENSA certification. This includes windows, bay windows, rooflights, residential doors with over 50% glazing, residential door sidelights/toplights, French Doors, Patio Doors and Bi-fold doors.
Items which do not fall under the remit of FENSA include conservatories, porches, new build properties, extensions, repairs and commercial work.
Which? Trusted Trader
One of the largest vetting companies in the UK, Which? have decades of experience assessing different products and businesses. We are proud to be listed as a Trusted Trader by them, which ensures we are offering excellent customer service and professional installations.
Feefo are one of three accrediting bodies where you can read testimonials about our hard work here in Yorkshire. You're unlikely to see many businesses supported by two of these reviewing bodies, so you know what you're getting with Coral who have three. Read our Feefo reviews today.
Checkatrade only advertise the best installers here in the United Kingdom - you won't see any subpar businesses with their logo on their website. Better yet, from hundreds of reviews, we at Coral boast a near perfect score for our performance through the installations process.
We use Pilkington glazing in our high quality uPVC and aluminium home improvements. We believe that they offer the highest quality glazing on the market, which is nothing less than our customers deserve. You get optimal thermal efficiency when you choose a Pilkington installer.
Coral are keen to buck the trend of the home improvement industry by being as eco-friendly as possible. We support the Environmental Agency by offering recycled products where possible and recommending repairs and facelifts over brand new products.
