See for yourself.
Good job, well done
Replaced 7 windows and a door. the lads that came did a great job and in a good manner. A catch on one of the windows didn't work correctly and was spotted and reported for us, the catch was fixed two days later with no fuss. All in all we would recommend coral without hesitation, both for the quality and the price. We will be getting in touch with them shortly to update our conservatory.

Thank you for taking the time to leave Coral Windows a 5* Review, we're delighted that you are happy with your experience with us & thank you for recommending us to your neighbours. We really appreciate your feedback. Kind regards The Customer Service Team
Fantastic experience from start to finish
From the beginning of our experience with coral up to the finished work, was so stress-free and easy. From the excellent salesperson who was very respectful and more importantly to the point with no pushy tactics and came back to go through the paperwork with the same respectful manner. All the communication with the company was also easy and to the point, the fitters were amazing they were quick and cleaned as they went. We had a complete upgrade of all windows and doors to triple-glazed to help with energy bills, they were very competitive on price. As well as help with noise reduction and heating costs we absolutely love the look and security of our new windows, I would highly recommend Coral

How we became a Which? Trusted Trader

Which? Trusted Trader is a program developed by the consumer watchdog organisation Which? to help consumers find reputable tradespeople and businesses. Coral underwent assessment by ‘Which?’ in 2017, with their trading standards professional ensuring we met the stringent criteria set out to obtain our ‘Which? Trusted Trader’ endorsement. 

We have continued to meet these criteria as Which? Trusted Trader conduct regular and ongoing checks with those who have achieved endorsement to make sure they still meet the exceptional standards needed.   

The assessment started with a detailed application that included information about our business, qualifications, experience, and customer references. This initial step allows Which? to gather essential background information about the company.

The Which? Trusted Trader Assessment process included various independent reports on all aspects of our company to provide certainty in their findings, ensuring we are reliable and trustworthy, and sealing our reputable services with their approval. 

These assessments include four main components: Customer satisfaction, Interview and Assessment, Business Procedures, and Credit Report.

Customer Satisfaction

The Which? Trusted Trader team contacts a selection of recent customers from a company’s most recent work to check references and satisfaction with the work that has been completed for them.

Interview and Assessment

The visit includes an assessment of various aspects of the business such as administrative processes, documentation and complaints procedures. There’s also an in depth interview carried out by the trading standards profession to understand every aspect of how the applicant’s business operates.

Business Procedures
