    "Lee came at short notice to disconnect the fire alarms and check the electrical supply following a leak up stairs which caused flooding through the ceiling. Provided perfect advice to let the water dry out and followed up with testing all the electrics to ensure no severe damage was caused."

    Trader reply: "Thanks James, glad we could safely get your supply back on for you at that hour"
