The Standing Charge Doesn't Care If You Have a Booking

The cottage that earned nothing and cost £41

A two-bedroom unit in the Peak District sat empty for eleven days in February. No bookings. The owner had left the heating at 19 degrees because the last guest complained about a cold arrival and they didn't want a repeat. Eleven days of holding 19 degrees through a cold snap, plus standing charges on both meters, came to roughly £41. The property earned nothing in that window. The £41 went out anyway.

That number is small on its own. Multiply it across a portfolio of fifteen units, each with its own scatter of gap nights, and the picture changes. Gap nights are not rare. They are the default state of most calendars outside peak weeks.

Where the money actually leaks

The standing charge is the part operators forget. Electricity and gas both carry a daily fixed charge whether you burn a unit or not. Across two fuels, that is often 80p to £1.20 a day per property before anyone turns a tap. On an empty unit, that charge is pure overhead. You cannot avoid it without disconnecting the supply, which you will not do.

What you can control is everything above the standing charge. Holding an empty property at occupancy temperature is the most expensive habit in the business. Each degree you hold costs roughly the same as if a guest were in residence, except no one is there to value it.

The trade-off operators reach for is the cold setback to nothing. Turn it all off. That saves the most, and it works in mild weather. It fails in two ways. First, a frozen pipe. Second, a guest arriving into a property that takes four hours to warm and reads cold on the review.

Frost protection is not the same as comfort heating

A pipe bursts at minus four, not minus one. Water expands as it freezes, and the pressure builds in the coldest, least insulated runs: the loft, the external wall, the unheated utility. By the time the air in the hall reads zero, those runs have been below freezing for hours.

Frost protection means holding the fabric of the building above the danger line, not holding the rooms at comfort. A setback floor of 7 to 10 degrees does this for most UK and Irish properties. It costs a fraction of holding 19. A unit held at 8 degrees through that same February gap would have cost closer to £18 in heating, against £41 at comfort temperature. Across fifteen units over a winter, that difference is real money.

The catch is that a fixed manual setback is a guess. Set it once in November and you are either wasting heat in a mild week or running too cold in a freeze. The weather does not hold still, and neither does your calendar.

The two states most operators run, and why both are wrong

State one: leave it warm

The property is always ready. Arrivals are never cold. You also pay comfort rates on every empty night, which is most nights for most units most of the year. This is the expensive safety.

State two: turn it off

The bills look great in spring. Then a guest checks in at 4pm to a 12-degree lounge that will not reach 20 until 8pm, and you get a review that mentions the cold. Worse, a hard freeze finds an unheated property and you are paying for a plumber and lost bookings while the unit dries out.

Both states ignore the one piece of information that should drive the heating: the booking calendar.

The calendar already knows

You know when the next guest arrives. The check-in time is in the booking. The gap before it is in the calendar. The only thing missing is heating that reads that calendar and acts on it without you remembering.

This is the work Alfred does. It holds a frost-safe setback through the gap, watches the outside temperature so the floor rises in a genuine cold snap, then warms the property to arrival temperature ahead of check-in. A 4pm arrival into a stone cottage needs the heating on by early afternoon. Alfred starts it based on how that specific building actually warms, not a fixed timer that is wrong half the year.

The operator gain is not one big saving. It is the removal of two failure modes at once: the expensive empty unit and the cold arrival. You stop choosing between them.

What to check this week

Pull your gap nights for the last month. Count them. Most operators underestimate by half. Then look at what your heating was doing during those gaps. If it was holding comfort temperature, you have found your leak. If it was off, check your overnight lows against the frost line and ask whether you got lucky.

The standing charge you cannot fix. Everything above it, you can.
