Copper Prices Hit 18-Month High as Supply Tightens
Copper futures on the London Metal Exchange (LME) surged to $9,906 per tonne (£7,800 GBP | €9,126 EUR | A$15,210 AUD | C$12,560 CAD) this week, reaching their highest level in 18 months as supply disruptions at major Chilean mines continued to weigh on global inventories.
The price rally has been driven by a combination of factors: reduced output from the Escondida mine — the world’s largest copper producer — alongside growing demand from electric vehicle manufacturers and renewable energy infrastructure projects across Europe and Asia.
Impact on Pipe Prices
Retail copper pipe prices have risen approximately 8–12% over the past quarter in response to the LME move. Trade customers with fixed-price contracts are currently insulated, but merchants have signalled that price list updates are expected in May 2026.
Screwfix and Toolstation have both confirmed price increases of 6–9% on Type L and Type K copper pipe effective from 15 April 2026. Wholesale merchants including Wolseley and BSS Industrial are expected to follow with updated price lists in the same period.
Scrap Copper Prices
Scrap yard buying prices have tracked the LME closely. Bright Wire (No.1 grade) is currently trading at £6.63/kg ($8.42/kg USD | €7.80/kg EUR | A$13.01/kg AUD) at UK yards, up from £5.90/kg three months ago.

Type K vs Type L vs Type M: Which Copper Pipe Should You Use?
Choosing the right copper pipe type is one of the most important decisions in any plumbing or HVAC project. The three main types — K, L and M — differ primarily in wall thickness, which affects pressure rating, cost and application suitability.
Type K — Heaviest Wall Thickness
Type K has the thickest walls of the three grades and is rated for the highest pressures. It is the standard choice for underground service lines, commercial installations and any application where the pipe will be buried or subject to physical stress. It costs approximately 20–25% more than Type L.
Type L — The Industry Standard
Type L is the most widely used copper pipe grade for above-ground domestic and commercial plumbing, heating systems, and HVAC. It offers an excellent balance of pressure rating, durability and cost. The majority of plumbing supply merchants stock Type L as their primary product.
Type M — Thinnest Wall, Lowest Cost
Type M has the thinnest walls and is the most economical option. It is suitable for low-pressure domestic applications such as hot and cold water supply in residential buildings. It is not recommended for underground use or high-pressure commercial systems.
Always check local building regulations before specifying pipe type. Requirements vary by country and application.
