Picking an electric radiator online isn’t as straightforward as it seems. Choose the wrong supplier and you’ll end up with a heater that can’t keep up, a warranty that nobody actually honours, and a customer service team that vanishes once your payment clears. The best UK online retailers for electric radiators pair a genuinely broad product selection with real support after the sale, and knowing which ones actually deliver on that makes a real difference.
Why Online Shops Matter for Electric Heating
Online-only electric radiator retailers carry a structural advantage over traditional trade counters and DIY superstores: lower overheads mean more of the budget goes into product quality and support rather than shopfront rent. They also tend to hold deeper stock, offer more detailed specification tools, and publish full warranty terms upfront.
That matters because electric radiators are a considered purchase. A unit rated at 1,500W by one manufacturer may not deliver the same usable heat as the same wattage from another, and very few high-street stores carry the range needed to compare models side by side. Online shopping closes that gap. Free delivery, transparent pricing, and returns policies that reflect genuine confidence in the product are now the baseline expectation from any reputable retailer, and the five shops below meet it.
1. Best Electric Radiators
What it does: Best Electric Radiators is a UK-based online-only retailer specialising in wall-mounted, slimline, smart, plug-in, designer, and vertical electric radiators, alongside towel rails, underfloor heating, and electric water heaters. The shop has been trading for over 11 years and is one of the largest dedicated electric radiator retailers operating purely online in the country.
Where it shines: The site holds a 4.8 out of 5 Trustpilot rating from over 1,400 reviews, making it the top-rated electric radiator company on the platform. Free UK delivery with a 48-hour turnaround, a 10-year body warranty with a 2-year electrical parts warranty, and 30-day returns are all standard. Customer support runs seven days a week, and lifetime telephone support continues after purchase, not something most retailers offer. Buy Now, Pay Later is available through both PayPal and Klarna. On-site tools including a Radiator Size Calculator and a Buying Guide help buyers size correctly before ordering. Pricing is shown with no hidden charges added at checkout.
Range and pricing: The product range spans models from £195 (Slimline Digital Electric Radiator) through to ceramic and WiFi-controlled units. The price shown is the price paid.
2. UK Radiators
What it does: UK Radiators launched in 2012 with a deliberately positioned offer, above the budget end of the market and below the premium pricing of design-led boutiques. The Colchester-based company sells electric heating, towel rails, dual-fuel options, column radiators, valves, and a full range of accessories, primarily through its ecommerce channel.
Where it shines: The company’s returns policy is notably flexible: rather than applying rigid conditions, they assess each return on its merits and issue refunds where products don’t meet expectations. Free delivery covers every UK address, with next-day delivery available. Trade buyers benefit from a standing 12.5% discount on every order, plus further deals through the year. With 2,676 Trustpilot reviews reporting positive experiences on quality and service, the customer base is established. UK Radiators has also participated in independent radiator testing comparing heat outputs across five retailers, which speaks to a degree of product confidence.
Range and pricing: Specific product pricing isn’t listed publicly, so buyers will need to browse the site directly for current figures. The selection covers both practical and designer styles.
Worth checking: No formal warranty terms were publicly detailed at the time of writing; it’s worth confirming these before purchasing.
3. Rointe UK
What it does: Rointe started as a small artisan electric heating company in Spain in 1985 and is now part of the Holdenmur Group, a multinational specialising in electric heating. The UK arm is based in Peterborough and distributes through the website and an authorised professional sales network.
Where it shines: The standout feature is the 20-year guarantee on electric radiators, one of the longest in the market and a signal of confidence in product longevity. Rointe’s Smart Adaptive Inverter Technology reportedly cuts stabilisation power waste by up to 80%. All radiators are made from recycled aluminium alloy certified to ASI environmental standards. The company received the German Design Award 2025 in the Excellent Product Design, Energy category for its EoniQ WiFi model and holds an Ecovadis Bronze medal. With over 200 employees across Europe and presence in more than a dozen countries, the supply chain is well-established.
Range and pricing: Rointe covers radiators, towel rails, underfloor heating, and domestic hot water options. Pricing isn’t publicly disclosed, so buyers contact the company or purchase through an authorised distributor.
Worth checking: The professional-network sales model can make it harder for direct consumers to compare prices or access the full range without going through a third party.
4. Herschel Infrared
What it does: Herschel Infrared, registered in Bristol, has been manufacturing infrared heating panels since 2008. The company positions itself as a global leader in infrared technology and covers indoor panels, outdoor heaters, and commercial heating options.
Where it shines: Herschel’s Comfort panels are the only infrared panels on the UK market tested to international standard IEC60675 for radiant heat output, and the range received European Quality Label certification in 2025. The company is also the first infrared supplier to run an accreditation programme for dealers and installers, which matters for projects where professional installation is involved. Manufacturing uses renewable energy and 100% recyclable packaging. A UK Production Facility opened in Bristol in 2023, increasing domestic capacity. The website offers online heating calculators for sizing.
Range and pricing: Products cover slimline indoor panels, stylish outdoor heaters, and high-output commercial units. Pricing isn’t publicly listed; buyers use the site’s specification tools or contact the company directly.
Worth checking: Infrared heating works in a different way from convective radiators. It heats surfaces rather than air, so it isn’t a direct swap for a traditional electric radiator in every situation.
5. The Electric Heating Company
What it does: The Electric Heating Company (EHC), founded in 2005 and based in Blantyre, Lanarkshire, covers the broadest product scope on this list. Beyond electric radiators, the company sells electric boilers (2kW to 100kW), unvented cylinders, solar products, water heaters, towel rails, and electric fireplace suites.
Where it shines: EHC holds an ‘Excellent’ Trustpilot rating of 4.8 out of 5 and has won national customer service awards. The business serves a wide client base, from residential properties and sheltered housing to tower blocks, hotels, offices, and schools across Aberdeen to Devon. Social housing clients benefit from a Total Care Package supporting tenants through the process. Pre- and post-sales technical support, project specification assistance, and installation advice are part of the standard offer. Controls are designed to work for both installers and homeowners.
Range and pricing: Electric boiler prices are displayed on the site with both VAT-inclusive and exclusive figures, running from approximately £659 to £3,271. Radiator pricing is also displayed transparently on the website.
Worth checking: The breadth of the product range means EHC isn’t a specialist electric radiator retailer in the way some others on this list are, so buyers focused on a wide radiator selection may find the choice narrower.
How to Compare Electric Radiator Retailers
A few things separate a genuinely useful electric heating shop from one that looks good on the surface.
Warranty terms are worth far more attention than most buyers give them. Two years is really the bare minimum; anything that stretches to 5 or 10 years on the body itself signals that the manufacturer genuinely believes in what they’ve built. Some retailers push this much further – Rointe’s 20-year guarantee being the most striking example – and that sets a completely different expectation.
Delivery speed and return flexibility aren’t small considerations when the product is heavy. A failed drop-off or a radiator that doesn’t fit the space is a genuine logistical headache. Free UK delivery is now expected from any serious retailer; what actually separates them is what happens once the box is at your door. Post-purchase support – especially for setup questions or technical issues – is where you can clearly see which retailers treat the sale as a starting point and which ones treat it as a full stop.
Pricing transparency is worth checking before committing. Some retailers display final prices clearly; others require you to register, call, or go through a distributor before you can find out what a product costs.
Bottom Line
The best UK online shops for electric radiators offer more than just a place to buy. They provide specification guidance, long-term warranty cover, and real help once the unit is on your wall. What’s right for you depends on the actual job: a straightforward wall-mounted swap, a whole-home heating overhaul, or something more specialised like infrared panels or high-output commercial units. Each retailer on this list covers different ground, so matching your supplier to your specific need will always beat buying on price alone.
