Ten years ago

Ten years ago, a builder fitted a towel rail but is no longer around. So I visited the web to understand my options. It was fantastic to speak to Jackie on the phone who went out of her way to understand my situation. She gave me instructions and helped me order the valves needed to resolve the issue. Thank you.

Zehnder Charleston with welded on feet

I have taken delivery of a Zehnder multi-column radiator with welded on feet. Unfortunately, the wall fixings enclosed are not suitable for the installation of the radiator in front of a large skirting board. Longer wall brackets are required for the rear feet to stand forward of the skirting board. Zehnder UK directed me towards Jackie, a truly wonderful person, who has located the required parts in France and confirmed their delivery to me in 3-4 working days. Perfect!

confirmation order issue

I had an issue with an order I had placed but did not receive confirmation for. After speaking to 3 individuals a few times and over 3 day period I was just getting the same response "Just Wait and see" Today after speaking to Casey, it was all sorted out, and the issue resolved. Casey showed exceptional customer service and a very helpful attitude. A great asset for the company. Keep up the great work!!

Helpful and efficient experience

From my son discussing the part needed for my MVHR with Gareth and passing me over to Jackie for all the paperwork, I must say she responded very promptly and I even received a smiley emoji. Efficient and friendly. Thank you for all your help.😏

Excellent Customer service!

I have Zehnder fans throughout my newbuild house. On contacting my builder (Avant) customer services, I was told to deal direct with manufacturer as I'd reported excessive noise from kitchen extractor. I contacted Zehnder and was asked to send a video of the fan and images to let Zehnder check warranty. I received a very prompt response advising a replacement had been sent out which I quickly received. Excellent customer service!

Amazing service levels

I was desperately looking for an extractor fan to replace / match an existing one which was no longer available. I dealt with Jackie who was extremely helpful and supplied all the information and specifications I required to make a decision. The replacement will be a direct fit with only very minor wiring alteration - exactly what I needed. After my initial email enquiry, to my surprise, I think I got a reply within the hour, I received a quotation to enable me to place an order the same day. This was again followed up by Jackie after Easter, on the Tuesday checking all was to my satisfaction. I was amazed at the service I received and most thankful...

Extremely helpful after sales service.

Had a small baffling problem with my radiator, which I'd ignored for years. When I decided to tackle, they were super helpful and sent me a new part, no questions asked about time lapsed, receipt or how it got broken. Amazing.

Great service and products

Jackie has so much patience and quickly and politely deals with all queries. I have been delighted with my last two orders. Delivery is quick and the product is superb. I cluld give my plumber the tech specs off the website which wss useful. I had these rads in a previous house and the efficiency and heat output is superb. And of course they look great. Thank you all.
