Unvented Components Avis 

Fantastic service

Every supplier near me was 3 to 5 days at a minimum for this and I got it next day to Northern Ireland! Great website and selection. Would recommend to other professionals to use this company

Really, really kind and professional ladies in customer services here. I sent a photo of my old part on WhatsApp and the part number. A like-for-like part was identified and verified.
Really competitive price and further Royal Mail options for faster delivery.
Very well done Unvented Components! Excellent service

Ordered a new expansion vessel to replace a failed one. Arrived quickly and quality looked good plus fixed wall bracket as part of the vessel. Makes for a really secure fixing rather than some with a big jubilee clip arrangement. Happy customer.

I am glad Google found me this company. Beat competitors by a mile on price. Speed to process my order and get part to delivery firm, for next day delivery, was unbelievable. Ordered part at 9.43 and had an email from parcelforce at 10.15 saying it was being despatched. Arrived the next day at around 12 noon. Absolutely fantastic service, well done "Unvented", ten out of ten from me.

Unfortunately, on reception of the goods that I ordered from Unvented Components Europe, (easy ordering process and rapid delivery), the parts turned out to be incompatible with my installation. However, the returns process was rapid, unquestioning and efficient with the refund appearing in my account two days later. As a result, I wouldn’t hesitate to use Unvented Components Europe again in the future and they would be my first port of call.

Really competitive pricing, fast delivery and excellent communication. Had a faulty component which was replaced immediately and without hesitation(faults happen!!)

Excellent service in everyway, good price, fast delivery, amazing lady on telephone call, really went the extra mile to help with my order. Ordered a 3 bar pressure valve for my cold supply. Next day delivery.

Easy ordering with pictures and parts listings for your appliance. Good prices and options for shipping. Have recommended and will again.

Excellent professional advice and speedy service

Easy to use website , good product and price , good comms around delivery

Well done thanks

The item was exactly what l required and was dispatched the next day. A great company to do business with.

Our heating engineer recommended us as we needed a new pressure release valve. It wasn’t a straight replacement as our old one was discontinued. We got great advice, the new valve was dispatched the same day, email communications kept us informed on delivery and our new valve arrived safely packaged and earlier than expected. All in all a 1st class service all the way. Thank you.

Old pump had ceased and this new pump head made it so easy, no stuck isolating valves or drain down just 4 screws and reconnect wiring. The new pump head is a quality unit at an excellent price and arrived on time.

Mea and her colleagues were very helpful from the start.
I was guided to the correct part and said part came quickly at a competitive price. I was very impressed. Henry.

Excellent service and communication.
Very happy.
