Cast Iron Price per Kg: What UK Scrap Yards Pay and Why
Call three scrap yards about cast iron and you will hear three different numbers, and that is the first thing to understand about the trade. According to ScrapYardFinder analytics, the UK average for cast iron and heavy iron stood at £0.16/kg on 2026-08-25, while published ranges run much wider, and this guide explains what each figure measures, how weight and item form change a quote, and which ID rules apply before you sell.
Average UK price: £0.16/kg on 2026-08-25, per ScrapYardFinder (UK yard directory) · Estimated yard price: £0.18/kg, range £0.10–£0.26 (UK Metal Prices (UK price aggregator)) · Cash payments: banned in England and Wales under the Scrap Metal Dealers Act 2013, according to Scrap Local (UK scrap FAQ)

What is cast iron worth today?
What is the price of cast iron per kilo?
- The UK average was £0.16/kg on 2026-08-25, per ScrapYardFinder (UK yard directory), based on the last 90 days of data.
- UK Metal Prices (UK price aggregator) estimates cast iron, BMRA Grade 10 / Light Cast, at £0.18/kg with a range of £0.10–£0.26/kg, and notes that fewer than two yards publish that grade.
- ESS Expo (industry news site) gives an indicative range for cast iron and steel of £0.05–£0.25/kg for mid-2026.
These figures measure market rates, not a price list that a yard has to honour, so treat each one as a reference point.
The implication: a quote well outside £0.15–£0.18/kg deserves a second call before you load the van, not an automatic yes.
How much is 1kg of cast iron?
- At £0.16/kg, one kilogram is worth £0.16, based on the average in ScrapYardFinder (UK yard directory).
- Across the UK Metal Prices (UK price aggregator) range of £0.10–£0.26/kg, the same kilogram is worth between 10p and 26p.
- Most UK yards quote iron by the tonne, so divide a tonne rate by 1,000 to reach a per-kilo figure, according to QuickStop Metals (UK scrap dealer).
A single kilo shows the rate but not the yard’s terms, so the bulk figure decides more.
The catch: at one kilo, the gap between the low and high end of that range is 16p. The money sits in the bulk load, not the unit price.
How much is 100kg of cast iron worth?
How much cast iron per kg does a scrap yard pay?
- Multiply the quoted rate by the weight in kilograms. At £0.16/kg, 100kg comes to £16.00, and at £0.18/kg it comes to £18.00, according to UK Metal Prices (UK price aggregator).
- At the top of the UK Metal Prices range, £0.26/kg, the same 100kg reaches £26.00. At the top of the Accio range, £0.40/kg, it reaches £40.00, according to Accio (sourcing platform).
- The final weight is set on the yard’s scale at delivery. Licensed yards use an electronic weighbridge and print a ticket with the weight and the agreed rate for the day, according to Scrap A Vehicle (UK scrap guide).
Grade changes the multiplier. Mixed or contaminated loads are downgraded to a lower mixed grade, so cast iron should travel separately from aluminium, copper and steel, according to Scrap Local (UK scrap FAQ).
No source in the research sets a minimum load at which a cast iron trip pays for itself, so treat the 100kg figure as a planning number, not a threshold.
The pattern: the arithmetic is simple, so the real variable is whether the yard buys your grade at the rate it quotes.
Is cast iron valuable as scrap?
Do scrap men want cast iron?
- QuickStop Metals (UK scrap dealer) does not currently buy cast iron, heavy steel, light iron or offcuts. Among ferrous grades it buys only brake discs and Mixed Tool Steel.
- Cast iron snaps when struck while steel bends. Brake discs, old radiators and engine blocks are typically cast, according to QuickStop Metals (UK scrap dealer).
- A cast iron engine block is paid as auto cast by weight, but a complete engine with aluminium attached is paid at the lower grade unless the metals are separated, according to UK Metal Prices (UK price aggregator).
Buyers price by weight and grade, so the item’s name matters less than its metal and whether it sits apart from other metals.
A dealer that refuses cast iron outright, as QuickStop Metals does, shows that the words “cast iron” guarantee no buyer. The grade and the yard’s own list decide the sale.
What this means: sort radiators, blocks and loose pieces before the call, because mixed loads sell at a lower grade than separated ones.
Is it worth scrapping a cast iron tub?
What is the scrap value of cast iron baths in the UK?
- Cast iron baths are heavy, and buyers price cast iron by weight, according to UK Metal Prices (UK price aggregator).
- The sources reviewed do not price a bath, its enamel or its fittings separately, so no bath-specific rate was found.
- Net value equals the yard’s offer minus the cost of removal and transport.
Illustration only: at £0.16/kg, a hypothetical 50kg bath would return £8.00 before removal costs are counted, using the average in ScrapYardFinder (UK yard directory).
A bath pays only when the offer clears the cost of getting it to the yard. At £0.16/kg, a 50kg bath returns £8.00 before that cost is counted.
Upsides
- Weight is the one measurable variable you control before the call.
- Published averages give a planning range, with the UK average at £0.16/kg.
Downsides
- No source reviewed prices baths or fittings separately.
- Removal and transport costs come out of the offer.
- Bath acceptance is unconfirmed for any named yard in the research.
The catch: the yard’s offer is only half the sum, and removal costs decide whether the bath is worth scrapping at all.
What ID do UK scrap yards require when selling cast iron?
Steps before you sell
Rules differ by nation. Scotland has its own metal-dealer legislation and Northern Ireland uses different dealer registration, according to UK Metal Prices (UK price aggregator), so a procedure that works in England does not carry over.
- Bring photo ID and proof of address. Dealers must verify the seller’s full name and address, and a passport alone does not prove address, according to UK Metal Prices (UK price aggregator). Sellers must be at least 18, according to Scrap A Vehicle (UK scrap guide).
- Check that the proof-of-address document is no more than three months old, according to UK Metal Prices (UK price aggregator).
- Expect payment by non-transferable cheque or electronic transfer. Cash is not an option in England and Wales, according to UK Metal Prices (UK price aggregator).
- Accept a printed ticket showing the weight and the agreed rate for the day, according to Scrap A Vehicle (UK scrap guide).
- Confirm the rules where the yard sits. Ask which ID and payment rules apply, because Northern Ireland differs, according to UK Metal Prices (UK price aggregator).
Confirmed facts
- According to UK Metal Prices (UK price aggregator), cash payments for scrap metal are banned in England and Wales.
- According to UK Metal Prices (UK price aggregator), dealers must verify the seller’s full name and address and retain transaction records for three years.
- According to UK Metal Prices (UK price aggregator), proof-of-address documents must be no more than three months old.
What’s unclear
- The current cast iron rate in any single region, given aggregator ranges from £0.15 to £0.40/kg.
- Whether a named yard accepts cast iron baths.
- The price gap between cast iron and mixed ferrous scrap.
- Whether a minimum weight applies at a given yard.
The implication: the ID and payment rules are the fixed part of this decision, while the per-kilo rate is the part you must check on the day.
“Cast iron scrap value currently sits in the £0.15–£0.40 per kg range depending on grade and region.”
Accio (sourcing platform)
QuickStop Metals reports that it does not currently buy cast iron, heavy steel, light iron or offcuts, buying only brake discs and Mixed Tool Steel among ferrous grades.
QuickStop Metals (UK scrap dealer)
Cash is off the table for sellers in England and Wales, according to UK Metal Prices (UK price aggregator), which leaves the day’s per-kilo rate and the removal cost as the two numbers that decide the return. For a homeowner with a cast iron bath to shift, the choice is clear: confirm that the yard takes baths and quotes a rate before the van is booked, or leave the bath where it is until a yard confirms both.

Frequently asked questions
Is it cheaper to arrange collection or take cast iron to a scrap yard?
The research does not compare the two options directly. Add the van hire or collection fee to your trip cost, then subtract it from the yard’s offer for your weight.
Can I get paid in cash for scrap cast iron in England and Wales?
No. According to UK Metal Prices (UK price aggregator), licensed dealers pay by non-transferable cheque or electronic transfer.
How do I weigh cast iron to get an accurate quote?
Estimate the weight before you call, then accept the weighbridge figure at the yard. Licensed yards weigh on an electronic weighbridge and print a ticket, according to Scrap A Vehicle (UK scrap guide).
Does the price of scrap cast iron change from day to day?
Ferrous prices follow UK mill and export demand and can hold steady for weeks, according to QuickStop Metals (UK scrap dealer). Check the rate on the day you sell, because the ticket records that day’s agreed rate.
Are there minimum weights for selling cast iron to a scrap yard?
No verified source in the research sets a minimum load. Confirm the threshold with each yard before you travel.
Do I need to remove fittings from a cast iron bath before scrapping it?
The sources reviewed do not price enamel or fittings separately, so ask the yard before you remove anything. Mixed or contaminated loads are downgraded, according to Scrap Local (UK scrap FAQ), so keep the bath separate from other metals.
