Having found a place to live, the provision of gas, water, electricity and TV/Internet are of importance next. Most houses come with a meter for g/w/e installed. The reading is important when moving in and when leaving.
Houses can come with a variety of meters for either gas, water or electricity. For gas, there can be an old analogue or new digital one. For power, it could be a single meter, or two indicators separating high (day-time) and low (night-time) tariff. The low tariff is the cheaper one.
