Quick answer: The Underfloor Heating Store is a well-established UK retailer with a broad selection of electric and water underfloor heating products, useful design and technical support, downloadable installation guides and a Basildon showroom. It suits homeowners, self-builders and tradespeople who want a broad range under one roof. The main caution is that it is a retailer, not a one-stop installation contractor, so the design, product choice and installer still need checking against your project.
What is The Underfloor Heating Store?
The Underfloor Heating Store is an online underfloor heating retailer based in Basildon, Essex. The company says it was founded in 2008 by heating experts and serves customers ranging from individual homeowners and self-builders to architects, developers and other tradespeople.
That matters because it isn't a manufacturer producing a single UFH range. It sells products from several established names, including ProWarm, Warmup, Floorwarmers and Heatmiser. The product mix covers electric mats and cables, water-based systems, thermostats, insulation boards, fixing and adhesive products, plus related bathroom and wet-room items.
In practical terms, you can buy an individual component or put together a larger system. The retailer's "Build my Kit" tool and design or quote service are aimed at customers who already know what the project needs, while the showroom and technical team provide another route for anyone who wants help choosing a system.
What's good about it?
A broad product range
The main strength is choice. A single-room electric installation, a multi-room water system and a replacement thermostat can all be sourced from the same retailer. This is useful because compatible components matter. You need the heater, insulation, controls, floor sensor and fixing method to work together rather than just match the price.
The store also stocks multiple heater and control brands, so you aren't tied to one manufacturer. Its own brand guide highlights different strengths: ProWarm for its own electric and water systems, Warmup for connected controls and established electric products, Floorwarmers for smaller electric projects, and Heatmiser for wired and smart heating controls.
Technical help before and after ordering
The store provides sales and technical support by phone and email, and offers virtual appointments. Its contact page lists weekday opening hours for the sales, technical support, customer service and accounts teams.
That support is a genuine advantage over simply adding a loose cable or mat to a basket. The right advice depends on the subfloor, insulation, floor finish, room shape and whether the system is supplementary or the main heat source. A useful sales conversation should establish those points before it recommends a product.
The store also offers free quotes and design. A layout is particularly valuable for an irregular room, because a standard rectangle-sized mat may need cutting or alternative routing. For water systems, a detailed layout can help establish pipe lengths, circuit arrangement, manifold requirements and controls before materials are ordered.
Installation manuals and videos
The manuals library covers a useful range of ProWarm and related products. It includes electric mats, cable systems, wood foil, carpet foil and inscreed cable. The wet-system section includes single-room, multi-room, overlay-panel and low-profile installation methods, together with pumps, manifolds and controls.
There are also installation and setup videos for selected systems and thermostats. This is good practice for a DIY customer because it reduces the temptation to follow half-remembered instructions. A video can't replace the full manual, but the two together make it easier to check the sequence before the floor is closed up.
What do the ProWarm warranties mean?
ProWarm is the store's own brand, so its warranty terms deserve close attention. The store's warranty page lists different periods for different products rather than treating every component identically.
For ProWarm electric mats, cables and thermostats, the advertised lifetime warranty is conditional. The product must be installed by an approved electrician in line with the applicable wiring and Building Regulations requirements, and the product must be registered on ProWarm's website within 28 days. If that registration condition isn't met, the page says a standard one-year warranty applies.
The ProWarm CableSafe scheme is separate. It covers accidental damage to an electric cable during installation subject to its stated time limit, proof of purchase and compliance with the manufacturer's installation guidance. That can reduce the cost of a common DIY mistake, but it doesn't make the product immune to installation errors.
For water-based ProWarm products, the published periods vary by component. The warranty page lists 50 years for pipes, 25 years for thermostats, 10 years for manifolds, three years for ball and fill valves, and two years for wiring centres, actuators and pumps. The manifold terms also require power flushing and corrosion inhibitors.
The practical rule is simple: read the warranty for the exact product, not a headline elsewhere on the site. Keep the invoice, complete registration and follow the installation instructions. A long advertised warranty has limited value if a registration deadline or installation condition has been missed.
The showroom and buying experience
The Basildon showroom gives customers a chance to see heating systems, thermostats and insulation in person and discuss the project with staff. The showroom page lists weekday opening from 7am to 5pm, plus Saturday morning opening, and says appointments aren't required.
That is useful for anyone who finds product specifications difficult to interpret or wants to see different control options. It isn't a substitute for a site survey. Floor construction and the intended heat source still need checking before a final specification is agreed.
Online, the site offers detailed product information, account facilities, a kit builder and a quote request. Those tools are most useful when you already have a room plan or building drawings. If you don't, expect to be asked for dimensions, floor type, insulation details, heating source and the result you want from the system.
Delivery, returns and ordering
The store advertises next-day delivery, but this is a service claim rather than a guarantee that every order will arrive the next day. Product availability, order cut-off, the destination, the size of the consignment and other operational conditions can all affect the actual delivery date. Check the live delivery information for your basket and address before relying on it when booking trades.
Returns are one of the more important points to understand before ordering a heating mat or cable. The published policy asks customers to report damaged, faulty or incorrect goods within 48 hours of delivery. The store may ask for photographic evidence and will assess returned items before processing a refund or replacement.
Unused mats and cables must be returned in their original condition. Cut, unrolled or used products can't be returned, and the customer normally pays return postage. The policy also lists products it can't return, including adhesives, grout, primer, certain bespoke items, and any product that has been cut or unrolled.
That's reasonable for floor heating goods because an unrolled mat or cut cable can't safely be resold or credited as new. It does mean you need the correct size on the first attempt. For any system that isn't a simple rectangle, use the design service or ask for a written layout before placing the order.
Your statutory rights still apply. The store's terms say they don't affect those rights, and faults or misdescribed products are handled under the relevant consumer law. Still, the practical insurance is to inspect the order on arrival, photograph any damage and raise it quickly.
Who is it best for?
The Underfloor Heating Store makes the most sense if you:
- want a broad range of systems, controls and accessories from one UK retailer;
- need technical advice before choosing a system;
- want electric and water-based products compared in one place;
- need a product layout for a non-standard room;
- prefer phone support as well as online ordering;
- want to visit a showroom before making a larger purchase;
- are comfortable choosing the right system and arranging qualified installation separately.
It may be less suitable if you want a fixed installer to design, supply, fit and commission the entire system under one contract. The store supplies products and design support, but its core offer isn't a nationwide installation package. You may still need a qualified electrician for electric work and a suitably experienced heating engineer or installer for a water system.
That's not necessarily a weakness. A homeowner buying one electric mat can order the correct product without paying for a full site survey, while a trade customer may already have a heating engineer involved from the start. The key is to understand which service you are buying.
What should you check before ordering?
Start with the system, not the brand. Decide whether you need electric or water-based underfloor heating. Electric is common for a bathroom, kitchen or small retrofit. Water-based heating suits larger areas, whole-house projects and many low-temperature heat-source applications.
Next, get the installation conditions right. Check the subfloor, insulation, room dimensions, floor finish and maximum floor temperature. The floor covering must be suitable for radiant heating, and the thermostat needs a floor sensor where the product instructions require one. Our underfloor heating installation guide explains the main installation decisions.
Use the store's manuals to check the chosen product, but treat them as product instructions rather than a complete site design. A useful comparison of the two system types is in our electric and water underfloor heating guide.
For wet systems, the heat source and operating temperature need designing properly, especially when an air or ground source heat pump is involved. Ask for the pipe layout, manifold position, zoning, pipe spacing and control arrangement in writing. Don't treat a collection of compatible parts as proof that the complete system has been designed.
Finally, compare like for like. Record the exact product, specification, accessories, delivery charge and VAT treatment. A cheaper heater may leave you needing a different thermostat, floor sensor, insulation board or fixing system.
Our verdict
The Underfloor Heating Store is a credible one-stop shop for UK underfloor heating materials. Its strongest points are the range of brands, access to technical help, design support, downloadable manuals, a physical showroom and a clear warranty information page.
It isn't the right answer for everybody. A buyer who expects installation, commissioning and aftercare to come as one package may need to look elsewhere. A DIY buyer also has to take ordering, testing and installation seriously, especially because used, unrolled or cut heating products aren't returnable.
So should you use The Underfloor Heating Store? If you know what you need and value choice and support, it's a sensible place to start. If you're designing a whole-house or heat-pump system, use its design service and have the final layout checked by the person who will install it. If you're fitting a small electric room, the range and guidance are useful, but measure carefully and order the right product first time.
That gives you the best of the store's offering without expecting a retailer to make a technical decision for you.
