RadiatorBuy: online radiator retail with a focus on design and certification

RadiatorBuy is an online retailer specialising in radiators for domestic heating. Its catalogue covers designer, bathroom, vertical and traditional models, and the company presents itself as a supplier of premium-quality products built to last. The range is organised by design and orientation, with collections that include oval panel, flat panel, round tube, mirror and towel rail radiators, as well as traditional cast iron models.

The company states that its radiators are engineered to EN442 standards, a European norm for thermal output testing, and mentions BS standards in its meta description. It also offers a warranty of up to 25 years on selected products, a detail that appears repeatedly in the product listings and in the site header.

Product range and collections

The catalogue is structured around several radiator families, each available in multiple sizes and finishes. The main collections displayed on the site are:

• Designer oval radiators, including horizontal and vertical oval panel models.
• Flat panel radiators, in horizontal and vertical formats.
• Column radiators.
• Towel radiators and heated towel rails.
• Mirror radiators.
• Round tube radiators.
• Traditional cast iron radiators.
• Spares and accessories.

Within these collections, the site highlights specific products such as the Horizontal Oval Panel Radiator, available in widths from 413 mm to 1593 mm and in anthracite, white or black; the Vertical Oval Panel Radiator, with widths from 236 mm to 590 mm and lengths from 1600 mm to 1800 mm; the Horizontal Flat Panel Radiator in premium mild steel, with widths from 408 mm to 1428 mm and finishes in anthracite, gloss white or matt black; and the Vertical Flat Panel Radiator, a space-saving design with widths from 272 mm to 680 mm and lengths from 1600 mm to 1800 mm.

Radiators are also grouped by room application, with dedicated selections for living rooms, bathrooms, bedrooms and hallways. The site allows browsing by orientation, with separate vertical and horizontal collections.

Delivery, warranty and customer support

RadiatorBuy offers free delivery to mainland UK on its products. The company provides what it describes as reliable UK support and expert customer support, although no specific details about the support channels or response times are given beyond the contact options listed separately.

The warranty period varies by product, with up to 25 years mentioned for certain models. This is presented as part of the product information rather than as a universal guarantee across the entire catalogue.

Referral programme

The retailer runs a referral scheme called Refer & Earn. Participants can give friends 10% off every order and earn 8% cashback on each successful referral. The programme is free to join and is described as having unlimited earning potential.

Advice centre

The website includes an advice centre with articles on radiator selection and installation. One example is a guide to choosing radiator valves, covering angled, straight and corner valves, published in October 2026. The article explains the differences between valve types and how to match them to pipework and radiator inlet positions. This content is presented as general guidance for UK homeowners.
