Really great company. I had some damage to one radiator and after a short phone call, they took my order details and immediately arranged a replacement. I just had to repackage it to send it back with the courier when the new one arrived. Thanks Stelrad.

Website is easy to navigate through. The ordering process was smooth. Plenty of product availability and delivery was quick. Radiator was well packaged. Would definitely buy from stelrad again.

I called Stelrad to ask for an explanation on the codes relating to the rows of fins/depth of the radiators. That wasn't clear on-line but the lady I spoke to was very helpful and I was able to make my choice. I then ordered the rad I wanted on line. It arrived so quickly. I think the next day. The rad is perfect, neat and is exactly what I want. Good price too. I may replace some more radiators here as it will be a great upgrade to our house. Thank you.

I rang Amy to ask for help in getting the correct covers for my already purchased radiators. Ii gave her the order number but i still got top covers with tabs on but no holes in the sides for them to fit to. Also she said it didn't matter if i bought left or right sides as they are interchangeable. They are not as they have fittings at one end and also won't fit the top cover.

I bought 3 radiators from stelrad and they look great. The delivery was unfortunately delayed due to their courier but the team bent over backwards and sent the radiators out again to ensure I got them on time. Really great service.

Radiators turned up as scheduled, but on unpacking a few weeks later when plumber was available one had a visible chip and a scratch. Too late to return as work schedule could not be changed. Disappointing

Absolutely superb company. Wonderful range of products. We visited their showroom in Rotherham and Graham took a lot of time helping us to choose exactly what we wanted. The staff answer the phone quickly and make the ordering process easy.

The small radiator arrived with no damage to packaging. On opening, the 2 corners were damaged, obviously in the factory. Also using the stelrad messaging system, it wouldn’t send!

the radiator i ordered came on the day i was given, but because they have changed radiator sizes i had to order one 50 mm to small for my existing pipework so had to find a tail to fit,radiator is now in position and connected, and seems ok on the test heating run i gave it.

Ordered two radiators and an absolutely awesome price and the K2's look great ready for my heat pump install next week. Will definitely purchasing more rads direct from Stelrad.....

Reply from Stelrad Ltd
I replaced an old Stelrad K2 with a like for like replacement.
The body of the radiator is faultless.
However, the top grill and side panels flap about loose with no obvious way to tighten them.
Older Stelrads dont have this problem,

Just received my second batch of radiators to complete preparing my house for its conversion to a heat pump. Stelrad's big range of radiators made it easy to pick the best radiator for reach room.

Wonderful customer service dept. Calls are picked up quickly and staff are well trained and can sort out issues straight away, nothing is too much trouble.
Damages are promply replaced without question and even turned up next day.
The actual radiators seem high quality and fairly priced for such a designer look.
