Independently endorsed for quality and trust

Sashed is a Which? Trusted Trader, a recognition that signifies our commitment to providing exceptional service and high-quality products to our customers.

What is a Trusted Trader?

The Which? Trusted Traders scheme is a trading standard that highlights businesses that have passed an independent assessment of their services and customer satisfaction. Being a Which? Trusted Trader means that Sashed has been thoroughly vetted for our professionalism, reliability, and customer service. This includes checks on:

Customer feedback: We consistently deliver great customer experiences. Our customers’ feedback is always transparent, and we actively seek reviews to continually improve.
Professionalism: We maintain high standards of work, ensuring every project is completed with care and attention to detail.
Complaints resolution: In the unlikely event of a problem, we take pride in handling issues efficiently and fairly, making sure every customer is satisfied with the result.
Insurance and legal compliance: We are fully insured and comply with all necessary regulations, providing peace of mind with every project.

What is TrustMark and why does it matter?

TrustMark is the UK Government-endorsed quality scheme for tradespeople carrying out work in or around your home. Sashed is proud to be TrustMark registered, which means:

Technical competence: Our work meets recognised industry standards, giving you confidence in the quality and durability of our installations.
Customer protection: We follow a clear code of conduct, and TrustMark ensures there are safeguards in place to protect you before, during, and after the work is completed.
Commitment to excellence: Like the Which? scheme, TrustMark registration involves thorough vetting and ongoing compliance to maintain high standards.
