Firstly, my first telephone call to TRADE ACCESS PANELS, calling from France, was answered within 3 rings, Emma, was the lady I dealt with then
(and therafter), so continuity was gaurenteed. Then I needed my order to be shipped out to France..... Emma offered to obtain the quote. Then the export document was sent to me to complete.... complex, so I asked Emma for help.... She called the company and they had thought I was a company and not a private client, so they told her no need for the form to be completed..... GREAT SERVICE INDEED...... Ilived in the UK for 10 years.... Great service compared to here in France...... WELL DONE EMMA and the company,

First time purchasing from this company, bought an electric operating roof window, unfortunately there was slight damage on the lid. I informed them by email the same day, and the next morning a replacement arrived by special delivery, I couldn't believe how fast they were. As a contractor, this is the service and after care we are looking for. Definitely use them again and definitely recommend. I'm just sorry I couldn't give 5 stars as original had slight damage

Easy online purchase, quick delivery confirmation, reliable delivery (turned up exactly when they said they would) and great after sales service, (we lost the installation papers before installing but the team emailed us all the information immediately) and were readily available to answer any questions we had. Excellent value for money and great overall customer experience. Would highly recommend.
