A Hamptons house typically has four utility relationships plus trash. PSEG Long Island supplies electricity, the Suffolk County Water Authority supplies water across much of the county, National Grid supplies gas where mains exist, and a fuel dealer supplies oil or propane to most homes. Trash is run by your town. The guides below start with the steps to open each account, and the rental checklist covers what to ask the owner.
