How the Calculator Works
Our calculator uses the latest national average prices from UK scrap yards. We aggregate pricing data from multiple yards across the UK to calculate a fair market estimate.
The estimate shows a range because actual prices vary based on your location, the quantity you're selling, the condition of the material, and the specific yard's pricing on that day. Yards in areas with more competition typically offer better prices.
For the most accurate quote, contact your local scrap yard directly with details of the grade, weight, and condition of your steel.

Tips for Getting the Best Steel Price
1. Sort your steel by grade. Separating HMS 1 from light iron can increase your total payout by 20-30%. Yards pay less for mixed loads because they have to sort it themselves.
2. Remove non-metal attachments. Rubber, plastic, wood, and concrete reduce the value. Clean steel with minimal contamination gets better prices.
3. Sell in larger quantities. Most yards offer better per-kg rates for larger loads. If you have a small amount, consider accumulating more before selling.
4. Compare multiple yards. Prices can vary 10-20% between yards in the same area. Call ahead to get quotes before making the trip.
5. Watch the market. Steel prices fluctuate weekly. If the CFR Turkey benchmark is trending up, it may be worth waiting a few days for yard prices to catch up.
Frequently Asked Questions
How do you calculate the value of scrap steel?
Scrap steel value = weight (kg) × current price per kg for that grade. For example, 100 kg of HMS 1 at £0.22/kg = £22. The grade matters significantly: HMS 1 pays roughly twice as much per kg as light iron. Stainless steel pays 3-5x more than ferrous grades.
How much does a steel radiator weigh?
A single-panel cast iron radiator weighs 25-40 kg, and a double-panel weighs 40-65 kg. Modern pressed-steel radiators are lighter (10-25 kg). At UK cast iron prices of £0.15-0.22/kg, a typical single radiator pays around £4-9 and a double pays £6-14.
Is per-kg or per-tonne the better measure?
Yards usually quote per-kg for small-to-medium loads (under 500 kg) and per-tonne for skip-loads or commercial quantities. Per-tonne rates are typically 5-10% better than the equivalent per-kg rate. 1,000 kg = 1 tonne. Our calculator shows both.
