Every time you pour grease down the sink, you're laying the foundation for a £300 plumbing emergency. 300,000 UK blockages a year — 75% caused by cooking fat. A simple £13 kit stops it forever.
We're taught to wash our hands, brush our teeth, and take the bins out. Nobody teaches what to do with a frying pan full of oil after cooking bacon. The result: millions of litres of hot fat poured down British sinks every year — solidifying into rock-hard blockages that cost homeowners thousands.
90% of people know pouring grease is "probably bad" but do it anyway. Why? No alternative is visible. The bin melts. The recycling won't take it. An empty jam jar feels wrong. The sink is right there — so down it goes.
The Whitechapel fatberg was 250 metres long and weighed 130 tonnes. It started with millions of individual kitchen sink pours — each one small, each one invisible, each one layering onto the last until the sewer was a solid wall of grease.
Average UK drain unblock: £150-£300. Emergency callout on a Sunday after Christmas dinner: £400+. And that's if it's just your pipes. If the blockage is in the shared sewer and traced to your property, the water company can bill you thousands.
Plumbing callouts spike 85% between December 24-31. Turkey fat, goose fat, roast potato oil, gravy residue — all poured down the sink within hours of each other across the country. Water companies run Christmas fatberg awareness campaigns every year because it's that predictable.
Before the full blockage, there's the smell. FOG coats the inside of your pipes, trapping food particles that rot over weeks. It comes and goes. You check the bins, the fridge, the drains — and can't locate it. It's the grease layer. It always is.
Landlords and holiday let owners face the multiplied version: tenants who don't care about pipes because they don't own them. One AirBnB Christmas let can trigger a blockage that cancels the next booking and costs £500+ in emergency plumbing and lost revenue.
Three simple items that replace the "pour it down the sink" reflex with a 2-second alternative. No thinking required. No searching for an empty jar. Just reach, scrape, pour — done.
Heat-resistant metal canister with "GREASE" printed in big red letters. No mistaking it for anything else. Wide mouth for easy pouring. Holds 500ml — about 2 weeks of typical cooking. Dishwasher-safe lid seals odours.
Flexible silicone blade that scrapes every last drop of grease from pans, roasting trays, and baking sheets. More into the can = less down the sink. Heat-resistant to 260°C. Dishwasher-safe. Bright red so it doesn't get lost in the utensil drawer.
16-page illustrated guide: what FOG is, what it does inside your pipes, the 5 things you should never pour, what to do instead, and the true cost of one blocked drain. Includes a "Hosting a Big Meal?" checklist for Christmas, Eid, and Diwali.
"DON'T POUR THAT" magnet with a cartoon fatberg. Sticks to the fridge at eye level. The visual cue that interrupts the automatic sink-pour habit — exactly when it matters.
Behaviour change doesn't happen through guilt. It happens when the right action is easier than the wrong one. The kit puts a labeled can and scraper within arm's reach — so collecting grease takes the same 2 seconds as pouring it down the sink.
Pamphlets alone don't work — people know it's bad and do it anyway. The physical can and scraper create a new default: reach left for the can instead of right for the sink. Behavioural design, not a lecture.
The labeled can sits on the counter, not under the sink. Visibility is the behaviour change mechanism. You see "GREASE" every time you cook. The empty jam jar in the cupboard is invisible — and invisible things don't change habits.
The kit includes a "Hosting a Big Meal?" checklist. Christmas, Eid, Thanksgiving, Sunday roasts — the meals that produce 10x normal grease volume. The checklist goes on the fridge 3 days before guests arrive. Pre-emptive, not reactive.
Trade Pack: 10 kits in a landlord-branded box. Goes into every new tenancy welcome pack alongside the inventory and meter readings. Cost per tenancy: £5. Cost of one tenant-caused blockage: £300+. ROI: 60x.
Flat-pack design ships in a standard Amazon Small Letter box (£1.85 fulfilment). Fits through a letterbox. No signature required. The impulse-buy plumbing product that Amazon's "Frequently Bought Together" algorithm will pair with roasting tins and turkey basters.
Every plumber who unblocks a grease-clogged drain has a captive customer who just paid £300 and is furious at themselves. Hand them the kit as part of the callout: "Put this by your cooker. You'll never see me again." Plumbers become the distribution network.
Three SKUs from day one. Starter for direct-to-consumer. Party Pack for the hosting season gift market. Trade Pack for the plumber/landlord B2B channel. Low COGS, high perceived value, infinite repeat potential — every can eventually fills up and needs replacing.

Conservative estimates. UK has 28M households. 1.2M homes change hands annually (new homeowner gift market). 145,000 plumbing businesses in the UK (Trade channel). Christmas hosting season alone reaches 10M+ households cooking large meals within 72 hours. Amazon CPC for "fatberg" and "drain unblocker" keywords: £0.45-£0.90 — highly affordable acquisition.
Five forces converging to make a simple grease disposal kit a viable business right now.
The Whitechapel fatberg made international news. Thames Water's "Bin It, Don't Block It" campaign reaches millions annually. Public awareness of fatbergs has never been higher — and there's still no obvious consumer product to buy. This kit fills that gap.
A letterbox-sized product with £12.99 ASP and £4.50 landed cost. FBA fee: £1.85. Net margin per unit: ~£6.64. No warehouse. No packing. No post office runs. One pallet to Amazon, and the machine sells it. TikTok unboxing videos do the marketing for free.
When money is tight, a £300 emergency plumbing bill is devastating. A £13 prevention kit is an easy sell: "Spend £13 now or £300 later." The maths is undeniable, and the kit is a fraction of the cost of even the cheapest drain unblock.
1.2M UK homes change hands annually. First-time buyers have just spent their savings on a deposit. A blocked drain in month 3 is financially catastrophic. The Party Pack as a housewarming gift — practical, thoughtful, and protects their biggest asset.
Plumbers hate grease blockages. They're messy, smelly, and completely preventable. Most plumbers would rather sell 100 kits than unblock one fatberg. The Trade Pack gives them a product to hand to every customer — turning a reactive emergency service into a proactive prevention relationship.
Anyone who roasts meat, fries bacon, or cooks a Sunday dinner. 18M+ UK households cook with oil or fat regularly. They've all poured grease down the sink at least once. They know it's wrong. The kit gives them the alternative they never had.
Christmas, Eid al-Fitr, Diwali, Thanksgiving — the meals that produce 10x normal grease volume in 72 hours. Plumbing callouts spike 85% in the last week of December. A Party Pack under the tree or given to the host is the most practical gift nobody thinks to buy.
360K first-time buyers annually. They've never maintained a property before. Nobody gave them the manual. A housewarming Party Pack says: "Welcome to homeownership. Here's how to avoid your first £300 emergency."
2.6M landlords in the UK. Tenants don't care about pipes they don't own. A Trade Pack in every new tenancy welcome box costs £5 and prevents a £300 callout. For holiday lets, one blocked drain cancels the next booking — the kit pays for itself 60x over on the first prevented incident.
Yes — and that's the point. The problem isn't complicated. People pour grease down the sink because there's no alternative within arm's reach. The kit puts the alternative right there: a labeled can that can't be mistaken for recycling, a scraper that gets every drop, and a pamphlet that explains the £300 consequence. Sometimes the best business is making the right thing obvious.
Heat resistance (jam jars crack with hot fat), labeling (a jam jar says "recycle me" — the grease can says "GREASE" in red), the scraper (a jam jar doesn't come with a tool that gets every drop), and the educational pamphlet (a jam jar doesn't explain why this matters). But the real difference is psychology: a product designed for the job creates a new habit. A jam jar is improvisation — and improvisation fails when you're tired after cooking.
Three layers: (1) Distribution — plumber relationships and landlord supply contracts take years to build. (2) Brand — the "DON'T POUR THAT" magnet and the fatberg cartoon character become the recognizable face of grease awareness. (3) Content — the educational pamphlet, hosting checklists for every major cultural celebration, and the plumbing-facts social media engine become the authoritative voice on home FOG disposal. Anyone can sell a can. Few can build the brand.
300,000 UK sewer blockages a year. 75% caused by FOG. £90M in annual damage. Thames Water alone spends £18M/year clearing fatbergs. This is a genuine infrastructure problem caused by a behaviour gap. The kit closes the gap. It's a real business solving a real, measurable, expensive problem.
Amazon FBA + TikTok. Unboxing a "DON'T POUR THAT" magnet with a cartoon fatberg is inherently shareable content. Christmas hosting season: run ads targeting "Christmas dinner prep" keywords. Housewarming gift market: Etsy + Not On The High Street. Plumber distribution: trade shows + direct outreach to 145,000 UK plumbing businesses. The product is the marketing — it's so simple and obvious that seeing it once creates the "why didn't I think of that" reaction.
You bin it. The metal can is recyclable. Once full of solidified grease (usually 2-3 weeks of normal cooking, or after one Christmas dinner), it goes in the general waste — exactly as water companies advise. Then you buy a replacement can. The refill model: starter kit includes the scraper and magnet (keep forever), replacement cans sold in 3-packs for £9.99. Recurring revenue from a consumable product.
