Have heard reports of damaged radiators delivered from other firms. Stelrad was well packed and arrived in good condition. The fitters are nw scheduled for August - so cannot comment on it working.

Easy from order to delivery and radiators perfect and undamaged great service

Reply from Stelrad Ltd
Great service and I only made a small purchase, wouldn't hesitate to use again rather than plumber merchants

Reply from Stelrad Ltd
Great to be able to purchase spare parts for my rad rather than having to buy a whole new radiator.

The radiator I ordered unfortunately arrived damaged. I called Stelrad to explain and a new radiator was immediately sent out, which arrived the next morning. Stacey who assisted me in getting the replacement sent out couldn’t have been more helpful. You only tend to find out how good a company is when things don’t quite go to plan. I couldn’t fault the after sales provided by Stelrad ⭐️⭐️⭐️⭐️⭐️

Stelrad themselves are excellent - really good customer service staff who answer the phone quickly and no quibbling if something has gone wrong. But they are let down by outsourcing their deliveries - presumably to the lowest bidder - rather than employing their own in-house delivery staff. I ordered one radiator. It arrived with a big dent in the top; it had been dented while inside then packaging. Stelrad immediately arranged for the damaged radiator to be collected and a new radiator delivered, which Stelrad said would be done by the same delivery staff in one visit. Actually I then received messages from delivery companies, and one delivery company collected the damaged radiator on one day and a second delivery company delivered the replacement radiator on a second day. Hence to get one radiator, I had to stay at home for three days.

I've had a first rate overall experience from Stelrad starting with the detailed technical information available to help select the right size and type of radiator. The ordering was straightforward and delivery was made 2 days after order. The radiator materials, workmanship and overall finish are excellent and should give many years of trouble free service.

From the initial enquiry to sales received competitive quotation and placed order.
Delivery was very quick and the towel rail was packaged very well.
Highly recommend going direct to Stelrad for your next purchase of any radiators & towel rails

Good radiator well built and all parts as expected.
Delivered as scheduled but not next day as paid for.

Reply from Stelrad Ltd
When I placed my order I could choose a delivery day, and this was honoured.
My plumber unpacked the radiator a couple of weeks after delivery and found that the the top grille was damaged. I received a replacement grille from Sterlad within 48 hours of contacting customer services.

Reply from Stelrad Ltd
Very prompt despatch and delivery. Radiator is very well packed so absolutely no damage. And it's great to buy direct

Reply from Stelrad Ltd
I found it very easy to complete my order and delivery was excellent. Would definitely recommend you to anyone.

Quality radiators and British made. I fitted Stelrad radiators to the house in 1991. Changing them now to increase the sizing in readiness for a heat pump. Plenty of life in the old ones. Secret is to use a corrosion inhibitor.

Radiators were delivered extremely quickly. Central heating guy has put them in now and they look great. Great price and excellent service. Will definitely be using this company again

Reply from Stelrad Ltd
I'd ordered 3 radiators and, because they were large and heavy, I was unable to check them before the plumber came to instal them.
Unfortunately one of the radiators was damaged in the top front left hand corner which is quite noticeable.
On contacting Stelrad they immediately offered to replace the radiator and either pick up the damaged one when delivering the replacement or else picki t up after it had been swopped oved which I thought was extremely good customer service.
I am pleased with the quality of the materials of the radiator and very grateful to Stelrad for their customer service. I will highly recommend them in future.
