If you’re selling products within the home, DIY or garden sectors, there’s a good chance B&Q Marketplace will have already appeared on your radar. Kingfisher reported £445 million in gross merchandise value for B&Q Marketplace in 2025/26, showing the scale the channel has reached.
The biggest opportunity is access to customers who are already shopping on B&Q for these types of products. But just because your range performs well through Amazon, your own website or another marketplace doesn’t necessarily mean you can list the same products in exactly the same way and expect them to perform well on B&Q.
Before you even get to that point, you need to know whether your products are a good fit, what you’ll need in order to apply and how you’re actually going to manage another sales channel once you’re up and running.
What Is B&Q Marketplace?
B&Q Marketplace launched back in 2022 and allows third-party sellers to list products on diy.com and through the B&Q app alongside products sold by B&Q themselves.
It’s powered by Mirakl, and B&Q selects and verifies the sellers it allows onto the platform. Products sold by marketplace sellers are identified on the website so customers can see who they’re buying from.
Is B&Q Marketplace Right for Your Brand?
B&Q Marketplace will make more sense for some brands than others. If you’re selling home improvement, DIY, garden or other products that naturally fit with what people already visit B&Q to buy, there’s a stronger argument for adding it to your existing sales channels.
But product fit needs to go a little deeper than simply being in the right category. You need to look closely at whether there’s actually demand for the products you’re selling, where there might be gaps in the existing range and whether your catalogue genuinely complements what B&Q customers are already looking for.
And don’t assume that because a range sells well on Amazon it’ll automatically do the same on B&Q. Some products may transfer across perfectly well, while others may need to be positioned differently or simply aren’t right for the marketplace.
What Should You Prepare Before Applying?
Before applying to become a B&Q Marketplace seller, you’ll need to have certain information about your business and products ready for the verification process. Exactly what’s required can depend on what you’re selling, so it’s worth checking B&Q’s current seller information before you start.
Your product information also needs to be in good shape. That means having identifiers, specifications, suitable images and category information available, along with any compliance or safety documentation that applies to your products.
You’ll also need to know how orders are actually going to be handled once they start coming in. Delivery, returns and customer service all need considering, as does stock management if you’re already selling the same products through Amazon or other sales channels.
How the Application and Onboarding Process Works
B&Q operates a selected-seller model, so the first step is to apply and go through its suitability and verification checks. Preparing your business information, product data and operational plans beforehand can help you respond to questions during the application process.
Once accepted, you’ll move into the onboarding process where your account is set up and you can then start preparing your catalogue and offers. B&Q uses Mirakl to manage its marketplace, which is where much of this process takes place before your listings are checked and made live.
How long this takes will depend on the business and the size of the catalogue you’re trying to launch. The same applies to commercial terms, so we’d always recommend working from the information B&Q provides during onboarding rather than relying on fees or timescales quoted elsewhere.
Adapt Your Listings for the B&Q Customer
If you’re already selling on Amazon, copying those listings across to B&Q might seem like the easiest option, but the content isn’t necessarily going to work in the same way.
Titles need to clearly describe what the product is, while categories, attributes, dimensions and other specifications all need to be accurate. Images should help customers understand exactly what they’re buying, and if you’ve got different sizes, colours or other variations, those need to be set up consistently too.
It’s also worth thinking about why somebody is shopping on B&Q in the first place. They may be planning a specific job and need to quickly check whether a product is the right size and material, and whether it’s compatible with what they’re working on. Installation requirements and what’s actually included can also influence that decision.
Keeping this information accurate also reduces the chances of products ending up duplicated, in the wrong category or simply being difficult for customers to find.
Build a B&Q-Specific Pricing and Margin Model
Your existing pricing shouldn’t automatically become your B&Q pricing. Before deciding what to charge, you need to work out what each sale will be worth once all the marketplace fees and other costs have been taken into account.
That means using the commission and commercial terms you will have been given during the onboarding process and then factoring in the cost of the product, delivery, returns, promotions, VAT and any internal cost of managing the channel.
What matters most is whether the channel remains profitable once everything is accounted for, so having the lowest price isn’t always the right move. If you’re selling the same products elsewhere, you’ll also need to keep an eye on how pricing is being managed across each channel rather than allowing them to drift independently.

Get Fulfilment, Stock and Seller Performance Right
Getting products live is one thing, but you also need to be confident you can actually fulfil the orders as they come in. Stock needs to stay accurate across each of your sales channels, particularly if they’re all pulling from the same inventory.
Delivery promises also need to be realistic. Late orders, cancellations and poor tracking quickly become a problem, as can slow communication when a customer needs help with an order or return.
This becomes even more important with some of the products commonly sold through B&Q. Large, heavy or fragile items may need very different delivery arrangements to what you’re already used to, while seasonal products can create sudden changes in demand that need to be planned for well in advance.
You can have excellent listings and competitive prices, but they’ll count for very little if the operational side of the account isn’t being managed properly. Poor service can lead to negative reviews and make customers less willing to buy from you.
When B&Q Marketplace Consultancy Can Help
There are plenty of brands capable of managing B&Q Marketplace themselves, but there are also times when bringing in some additional expertise makes sense. Complex catalogues, onboarding delays, category or product data issues and poor visibility can all slow things down, especially when the internal resource simply isn’t there to deal with them.
Our B&Q Marketplace consultancy can help identify where those problems are and what needs to be addressed. If you’re already selling on B&Q or preparing to launch, get in touch to request an audit.
