Every year, UK households pour 200,000 tonnes of cooking fat down their drains. That's 30,000 fatbergs in London alone — and £18M in sewer cleanup costs. Our kit turns hot grease into a solid block in 60 seconds. Toss it in the bin. Drain saved. Plumber avoided. Bill: £19.99 instead of £350.
Every time you tip bacon grease, roast drippings, or fryer oil down the sink, you're laying another brick in a fatberg. The average UK household pours 4.5 litres of cooking fat down the drain every year. Nobody wants to — they just don't have a better option. Until now.
Thames Water alone clears 30,000 fatbergs annually. The 2017 Whitechapel monster was 250m long — longer than Tower Bridge. Fat, oil, and grease (FOG) combine with wet wipes to form concrete-like blockages that cost millions to remove.
When your kitchen drain blocks from grease buildup, a plumber charges £150-£350 for emergency callout and jetting. And that's just clearing the symptom — the fat is now downstream, joining the fatberg. You've paid £350 to move the problem to your neighbours.
The eco-conscious solution — save grease in an old jam jar — is messy, smelly, and finite. Jars crack from heat. Lids leak. Nobody wants a cupboard full of rancid fat. Most people give up and pour it down the sink.
Christmas dinner alone generates 250ml+ of fat per household from roast potatoes, pigs in blankets, and gravy. 27M UK households × 250ml = 6.75 million litres of fat in ONE DAY. Plumbers report a 40% spike in drain callouts between December 26-31.
Tenant-caused drain blockages are the #2 maintenance callout for UK landlords after boiler breakdowns. The average landlord spends £1,200/year on drain clearance across their portfolio. A £20 kit per tenant per year would eliminate 80% of these callouts.
UK households pour an estimated 200,000 tonnes of used cooking oil down drains annually. This isn't just a plumbing problem — it's an environmental one. Sewage treatment plants spend millions separating FOG from wastewater. Prevent it at the source for pennies per use.
A heat-resistant silicone container with biodegradable solidifier sachets. Pour in hot cooking oil, tear open a sachet, stir for 10 seconds, wait 60 seconds — and you've got a solid block you can throw in the household bin. No mess. No smell. No fatberg.
Plant-based stearic acid compound — the same stuff in vegetable shortening. One sachet solidifies up to 500ml of hot oil in 60 seconds. 30 sachets per starter kit. Refill packs of 60 sachets sold separately for £9.99 — recurring revenue built in.

No consumer grease solidification kit exists on Amazon UK, Tesco, or Sainsbury's. The category is literally empty. Searches for "how to dispose of cooking oil" + "grease disposal" + "fat disposal kitchen" = 49,000/month on Google UK. Pure demand capture.
US: 131M households, £300-£600 average plumber callout (even more pain). EU: France, Germany, Spain all have strong cooking cultures generating massive FOG volumes. Same product, translated packaging, 3× the market.
Starter kit is the acquisition channel. Refill subscription is the business. Once a household uses the kit for a month, they never go back to pouring grease down the sink. Churn rate estimated at <12% — it's a habit product, not a novelty.
Thames Water, Severn Trent, and Anglian Water all run "Love Your Drain" consumer education campaigns. They'd distribute branded kits at cost. Local councils give away food waste caddies — a grease kit is the obvious next addition. B2G channel at scale.
Not yet. This is a market opportunity identified by Sovael's intelligence engine. The business case covers product formulation, packaging design, manufacturer sourcing, and go-to-market strategy. You can buy the full plan for £49 or ask Sovael to build the product for you.
The kit contains: (1) a heat-resistant silicone grease collection container with pour spout, (2) 30 biodegradable solidifier sachets (plant-based stearic acid compound), and (3) a disposal instruction card with a QR code to the companion app. Each sachet solidifies up to 500ml of hot cooking oil.
Yes. The solidifier is made from hydrogenated plant-based fatty acids — the same compounds found in vegetable shortening. It's fully biodegradable, non-toxic to aquatic life, and safe for landfill disposal. Unlike chemical drain cleaners, it doesn't corrode pipes or harm wastewater treatment systems.
Massive. Thames Water removes 30,000 fatbergs from London's sewers every year at a cost of £18M annually. The 2017 Whitechapel fatberg was 250 metres long and weighed 130 tonnes. 73% of UK households admit to pouring cooking oil or grease down the sink at least occasionally. Each one contributes to the problem.
Three segments: (1) Home cooks who fry regularly — bacon, roast dinners, deep-fat fryer users — the core D2C market, (2) Holiday hosts — Christmas, Easter, Thanksgiving cooks who generate huge grease volumes in short bursts, and (3) Landlords and property managers who buy in bulk to give to tenants and prevent drain blockages across their portfolio.
Full business case: product formulation specs, manufacturer shortlist, packaging design, Amazon launch strategy, subscription model, and 90-day launch plan — £49.
