Best Selling Categories on B&Q Marketplace in 2025
Discover the best selling B&Q marketplace categories in 2025 — where buyer demand is strongest, competition is manageable, and margins are most attractive for sellers.
Choosing which category to sell in on B&Q marketplace is one of the most consequential decisions you will make as a seller. Get it right and you are working with the current of buyer demand — your products surface in front of shoppers who are actively looking for exactly what you offer. Get it wrong and even excellent execution struggles to generate the sales volume needed to justify the effort.
This article maps out the B&Q marketplace category landscape in 2025 — identifying where buyer demand is strongest, which categories have the best seller opportunity given current competition levels, and which product types are best aligned to the platform's audience and growth trajectory.
How to read this guide: Each category is assessed across three dimensions — buyer demand strength, current competition level, and typical margin opportunity. The goal is to identify categories where all three are favourable simultaneously, not just one.
The Leading Marketplace Categories in 2025
Garden and Outdoor Living
Garden and outdoor living remains the engine of B&Q marketplace activity. The category spans outdoor furniture, garden tools, planters, raised beds, water features, garden lighting, and outdoor heating — all areas where buyer intent on diy.com is extremely high. Marketplace sellers report that spring-to-summer demand in this category is particularly strong, with order volumes that can multiply several times over from January baselines by March and April.
- Best subcategories for new sellers: garden tools and accessories, outdoor decorative lighting, raised beds and planters
- Subcategories to approach carefully: garden furniture (high competition, high return rate on large items)
Bathroom Accessories and Fittings
Bathroom accessories — from towel rails and toilet roll holders to shower accessories, mirrors, and bathroom storage — represent one of the most consistently profitable categories on B&Q marketplace. Demand is year-round, average order values are meaningful, and the considered-purchase nature of bathroom buying means buyers are less price-sensitive than in commodity categories. The category has room for sellers who can offer distinctive finishes, quality at reasonable price points, and complete bathroom accessory sets.
- Best entry points: bathroom accessory sets, heated towel rails, shower accessories
- Key success factor: finish consistency across a range (buyers are often furnishing an entire bathroom)
Lighting
Lighting is a category that straddles B&Q's traditional home improvement DNA and the lifestyle home décor space. Indoor lighting — ceiling pendants, wall lights, table lamps, and smart bulbs — performs well year-round, with peaks in autumn and winter as buyers refresh their interiors ahead of the darker months. Outdoor lighting, including garden spotlights, pathway lights, and security lighting, peaks alongside the broader garden category in spring.
- Fastest-growing subcategory: smart and connected lighting solutions
- Compliance note: electrical products require appropriate safety certification
Outdoor Structures
Garden sheds, log stores, gazebos, pergolas, and garden offices represent some of the highest average order values on B&Q marketplace. Buyer intent in this category is very high — shoppers searching for a garden shed on diy.com are typically ready to buy — and the number of marketplace sellers is still relatively limited compared to the demand available. Sellers who can offer quality structures with clear assembly information, good imagery, and competitive pricing find this category particularly rewarding.
- Key challenge: large parcel fulfilment requires specialist courier arrangements
- Differentiation opportunity: clearer assembly guides and better imagery than most current listings
Power Tools and Accessories
Power tools and tool accessories attract highly motivated buyers who visit B&Q specifically because they are executing a project. While the branded power tool market is dominated by established names (Dewalt, Makita, Bosch), there is strong demand for compatible accessories, consumables, storage and organisation, and mid-range unbranded tools for domestic DIY users. Accessories and consumables often carry better margins than the tools themselves.
- Best margin opportunity: tool accessories and consumables (drill bits, saw blades, sanding sheets)
- Important: safety compliance documentation is essential for all power tools
Storage and Organisation
Home storage — garage shelving, shed organisation systems, workshop storage, utility room storage, and cable management — is a consistently strong category that often flies under the radar compared to more glamorous home improvement areas. Demand is year-round, the buyer profile is practical and project-driven, and competition from marketplace sellers is currently lower than in higher-profile categories. Sellers who can offer well-designed, clearly described storage solutions find a receptive audience on diy.com.
- Growing subcategory: garage organisation systems and workbench accessories
- Key differentiator: clear, accurate assembly and dimensions information
Flooring and Floor Care
Flooring accessories — underlay, floor care products, door bars, threshold strips, and installation accessories — represent a steady demand category with good average order values and relatively limited marketplace seller competition. B&Q sells significant volumes of its own flooring, creating natural demand for the accessories that buyers need alongside those purchases. Sellers who can position flooring accessories in the right categories can capture this adjacent demand effectively.
Emerging Categories Worth Watching
Beyond the established strong performers, several emerging categories are showing early signs of growing marketplace demand. Smart home products aligned with home improvement (smart thermostats, video doorbells, smart locks) are gaining traction as buyers increasingly treat these as mainstream home upgrades rather than specialist technology purchases. Home office and garden office accessories are another growing area as more UK homeowners invest in dedicated workspace solutions.
For sellers with the right product range, getting into these categories now — while they are still in their early growth phase on B&Q marketplace — mirrors the early-mover advantage that garden and bathroom sellers established over the past few years.
