How Old Is London's Housing Stock?
With 81% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Pre-1986 plumbing is not a rare legacy case in London — it's the dominant profile. The median build year of 1941 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in London were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

London: Remediation Cost in Perspective
Property equity in London sits at a moderate ratio to estimated remediation costs — a classification that reframes the household financial perspective from routine maintenance to deliberate budgeting, where most homeowners have a realistic path to addressing documented water and safety issues if they map the financial commitment against available resources before committing to scope.
Remediation costs are moderate relative to home values in London. The estimated $0–$800 range is manageable for most homeowners but still worth budgeting for. Home values are 79% below the West Virginia average.
Protecting Children from Lead in London
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
In recent monitoring under the Lead and Copper Rule, citywide samples for London have approached or crossed the regulatory action level on multiple occasions. Combined with 81% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.
