What it is
A small web shop built around one corner of DIY, such as fixings and fasteners, decorating supplies or garden and shed tools. You hold some stock yourself or use supplier delivery, and post orders to customers.
Your first three steps
- Choose a narrow niche and compare what existing online sellers charge for postage and delivery times
- Open trade accounts with two or three wholesalers and test your best-selling items with a small stock order
- Set up a simple online shop and list your first products with clear photos, sizes and descriptions
Who pays
Homeowners and small tradespeople who want a better range or advice on a specific type of product than a general shop offers.
How it makes money
You sell at a markup over trade prices. Multi-pack bundles, project kits and repeat orders from tradespeople help lift the average order.
Skills that help
- Product knowledge in your chosen niche
- Basic website and photo skills
- Packing and order handling
- Customer email support
Watch out for

- Check whether selling electrical tools or batteries means you need to register under producer responsibility rules
- Product liability and public liability insurance, plus cover for stock stored at home
- Running from home may need permission from your landlord or mortgage lender

Questions people ask
How much does it cost to start an online DIY shop?
Startup costs are typically around £1,500 to £7,000, depending on your website, how much stock you hold and your packing supplies. These are estimates, so a narrow range can help keep early costs down.
How much can an online DIY shop earn?
Monthly revenue is typically around £800 to £4,000, depending on your niche, range and marketing. The estimate assumes at least about 10 hours a week. Revenue is not profit, so allow for stock and postage, as bulky items can eat into margins.
What should I check before selling DIY supplies online?
Check the current consumer rights guidance on returns, refunds and clear pricing. Check with couriers and Trading Standards on posting paints, aerosols and chemicals, and whether producer responsibility registration applies to electrical tools or batteries. Also check insurance and landlord or lender permission.
