Utilities in an old building: bottles, meters and the winter bill

This looks at utilities from the practical end — what holds up once conditions stop being ideal.

Gas that arrives in a bottle

Many older buildings have no piped gas, so cooking and water heating run on refillable bottles delivered or collected locally. A bottle is exchanged rather than refilled in place, and there are distributors and shops that handle this routinely. Running out mid-shower is the classic experience, which is why households keep a spare bottle rather than a single one.

Bottles are heavy and buildings have stairs, which is a genuine consideration for anyone living several floors up. Where mains gas exists, it is billed by meter like anywhere else, and the difference between the two systems is entirely about the building.

Water heated on demand

Instant water heaters are common, warming water as it passes rather than storing it in a tank. They are efficient in the sense that nothing is kept hot unnecessarily, but they deliver a limited flow rate. Running two hot taps at once will often defeat one, which is a plumbing constraint rather than a fault.

On an ordinary week, they also need a minimum flow to ignite, which is why a trickle of hot water sometimes runs cold. Servicing them matters, and a poorly maintained gas appliance in an unventilated bathroom is a genuine safety issue rather than an inconvenience.

The electricity bill

Electricity bills here typically combine a usage charge with a fixed element tied to the contracted power capacity of the property. A higher contracted capacity allows more appliances to run at once and costs more every month whether or not you use it.

Old flats with high contracted capacity and few appliances are paying for headroom nobody needs. Tripping the supply when a heater and an oven run together is the sign that capacity is set low for the way you live. Reviewing the contracted capacity is one of the few genuinely worthwhile things to do after moving into an old flat.

Heating, or the absence of it

Central heating is uncommon in older housing, and homes are heated room by room with electric heaters when they are heated at all. That is why winter electricity bills rise so sharply and why people describe the indoor cold as worse than colder countries.

Buildings were designed for a mild climate with thick walls and no insulation, which handles summer better than winter. Damp compounds it, because moist air feels colder and takes more energy to warm than dry air does.

Dehumidifiers are used widely and often make more difference to comfort than an additional heater.

Water and the building

Water is metered per flat in most buildings, and bills combine supply, wastewater and waste collection charges. Pressure on upper floors can be poor in old buildings, particularly where a pump has failed or was never installed. Leaks in shared pipework become a collective matter, which is one of the things a building association exists to handle.

Hard water leaves scale in kettles and heaters, and descaling is a routine maintenance task rather than an occasional one. Tap water is generally safe to drink, and any local advice to the contrary would come from the utility rather than from rumour.

If that does not fit your week, it is not a failure of willpower.

Setting it all up

Transferring accounts into your name requires identification, the tax number and usually a bank account for direct debit. Meter readings at the point of moving in protect you from inheriting somebody else's consumption and are worth photographing.

The market for electricity and gas is competitive, and switching supplier is possible though the savings vary. Bills are frequently estimated between readings, so submitting your own readings keeps them accurate. Sorting all of this in the first week avoids the common situation of a large corrected bill arriving months later.

The takeaway

Check the contracted capacity, photograph the meters, and buy a second gas bottle.

Small and repeatable beats ambitious and abandoned, almost every time.
