Paint is one of the most awkward things to get rid of in a London home. It can’t go in the kerbside bin when it’s still liquid, most recycling centres won’t take oil-based tins at all, and pouring it down the sink is a criminal offence that can carry a five-figure fine. Yet almost every half-finished renovation leaves a shelf of part-used tins behind.

Why Paint Is Trickier Than Most Rubbish
Every London borough’s bin collection contract excludes liquids – crews refuse open tins. Water-based paints (emulsion, acrylic) are benign once dry. Solvent-based paints (gloss, eggshell, enamel, varnish, creosote) are hazardous waste under the Hazardous Waste Regulations 2005 with EWC code 08 01 11*.
Two different problems, two different routes.
Water-Based Paints: Dry, Then Bin
- Open outdoors or in a ventilated room.
- For <1 cm: just leave the lid off for a few days.
- For 2–5 cm: stir in equal volume of sawdust, sand, clean soil, or cat litter.
- For >half full: decant into shallow trays or use proprietary paint hardener.
- Once solid, put tin (lid off) in black bin.
- Empty scraped-out metal tins go to metal recycling.
Never pour water-based paint down any drain.
Oil-Based and Hazardous Paints
Hazardous: gloss, eggshell, satinwood (if solvent-based), enamel, metal paints, varnish, creosote, wood preservers, thinners, white spirit, aerosol paint cans.
Never dry and bin. Legal routes:
- HWRC that accepts hazardous household waste.
- Licensed hazardous-waste collection – see hazardous waste disposal.
- For trade: consignment-note collection.
Tins must be sealed, upright, labelled, in original containers.
London HWRC Limits by Waste Authority
- NLWA: up to 5L water-based per visit. Oil-based generally refused except Hornsey Street (Islington) by appointment.
- WLWA: similar 5L cap. Abbey Road (Brent) main hazardous-paint site.
- ELWA: stricter; some sites refuse paint outright – need booked specialist collection.
- SLWP: bookable hazardous-household-waste slots for oil-based.
- Unitary boroughs (Bexley, Bromley, Greenwich, etc.) have their own arrangements – most take water-based to ~5L.
Always check before driving. See our tips guide.
Giving Unused Paint a Second Life
Several London boroughs host community paint-reuse schemes that accept part-tins and resell cheaply to community groups and residents. Listed under “paint reuse” on council websites.
Accepted: water-based emulsion/masonry at least quarter-full, readable label, never frozen. Not accepted: solvent-based, varnish, wood preserver, metal paint, aerosols, unlabelled.
Giveaway listings also work well for current-range emulsion colours.
Trade Painters and Business Waste
Commercial paint waste moves through licensed carriers with paperwork.
EWC codes:
- 08 01 11* – solvent-based paint/varnish (hazardous)
- 08 01 12 – water-based paint/varnish (non-hazardous)
- 08 01 17* – paint-stripping wastes (hazardous)
- 15 01 10* – packaging with hazardous residues
Asterisk = consignment note required under Hazardous Waste Regulations 2005. Keep for 3 years. Check carrier’s EA registration first – duty-of-care liability stays with producer.
Large Quantities from Renovations
- Book a one-off hazardous collection – licensed carrier brings containers, segregates water vs solvent, issues consignment note.
- Hire a lockable hazardous-waste container for the duration of works – standard on larger refurbishments.
If mixed with other rubbish, combine with a domestic rubbish removal and flag hazardous items.
Illegal Disposal: What Actually Happens
- Pouring down drains – water-pollution offence under s85 Water Resources Act 1991. Max £50,000 fine summary, unlimited + 5 years on indictment.
- Burying tins – illegal deposit of controlled waste under EPA 1990.
- Burning paint/rags – toxic smoke, statutory nuisance, fire risk.
- Leaving beside communal bins – fly-tipping FPN from £400.
- Unlicensed man-with-a-van – if traced to dump, householder prosecuted.
Lead Paint in Older London Properties
Pre-1970s London properties likely have lead-based paint on skirting, architraves, window frames, radiators, external doors – often buried under newer layers. Inexpensive swab tests from DIY shops confirm in minutes.
HSE rules: never dry-sand, power-sand, or burn off lead paint. Use chemical stripping or wet-scraping, collect waste on plastic sheeting, dispose under EWC 08 01 17* via licensed carrier. For larger areas, engage a specialist lead-paint contractor – especially where children or pregnant residents live.
Frequently Asked Questions
Only once fully solid. Liquid paint is excluded from London bin contracts. For water-based, stir in sawdust/sand/hardener until set, then bin with lid off. Oil-based and gloss must never be dried and binned – hazardous waste.
No. Water-based carries EWC code 08 01 12 (non-hazardous). Still can’t go in bin as liquid, but safe once dried. Solvent-based is 08 01 11* (hazardous).
Stir in equal volume of sawdust, sand, or cat litter. Sets in a few hours. For larger quantities, paint hardener sachets from DIY shops set a 2.5L tin in about 10 minutes.
Sometimes. Most route oil-based gloss through a separate hazardous-household-waste service. In North London, Hornsey Street (Islington). In West London, Abbey Road (Brent). Some East London sites refuse paint outright. Always check before travelling.
Most London waste authorities cap household drop-offs at 5L of water-based per visit. Similar or smaller allowance for hazardous. For larger volumes, a booked hazardous collection is cheaper than multiple trips.
Yes. Water-pollution offence under s85 Water Resources Act 1991. £50,000 max summary; unlimited fine plus imprisonment on indictment. Applies to water-based too.
