People often assume that running a home lift will send their electricity bill soaring. In reality a domestic home lift is one of the cheaper appliances in the house to run, and the bigger question for most owners is what happens in a power cut. This guide explains the running costs, how a home lift is powered, and how it behaves when the electricity goes off.
How a home lift is powered
Most domestic home lifts run from an ordinary mains supply, and many simply plug into a standard 13-amp socket rather than needing a special electrical installation. That is one of the reasons through-floor and self-supporting lifts are so practical to fit, as they do not demand the heavy power supply or machine room of a commercial lift. The lift draws a small trickle of power to keep its batteries topped up and uses a modest amount more while it is actually travelling.
What it costs to run
The running cost is low. A home lift uses only a small amount of electricity, because it runs for a few seconds at a time and sits idle the rest of the day. For most households the cost works out at a few pounds a month rather than anything that would noticeably change the bill. The exact figure depends on how often the lift is used and how far it travels, since a longer journey between floors uses a little more power, but in everyday terms it is an inexpensive appliance to own.
Our guides to the cost of a home lift and the cost of installing one cover the purchase and fitting side, which is where the real spending is, rather than the running cost.
What happens in a power cut
This is the question that matters most to many buyers, and the answer is reassuring. Mains-powered home lifts are fitted with a battery backup, so if the power fails while someone is in the lift, the battery has enough charge to bring the car safely down to the lower floor. You are not left stranded between storeys.
The detail to understand is that this is a safety feature, not a way to keep using the lift normally during a long outage. On most through-floor and shaft lifts the battery is there to complete the current journey and lower you safely, rather than to run the lift up and down until the power returns. Vacuum lifts work a little differently, using a controlled release of air pressure to lower the car gently in a power cut. Either way, the lift is designed so that losing power does not leave the user trapped.
Keeping costs and reliability in check
The single best thing you can do for both running cost and reliability is to keep the lift serviced. A well-maintained lift runs efficiently and the battery holds its charge, which is what makes the power-cut backup dependable when you need it. Leaving the lift connected to the mains so the battery stays charged is part of normal use.
At a glance
- Power supply: most domestic home lifts run on a normal mains supply, often a standard 13-amp socket.
- Running cost: low, typically a few pounds a month, because the lift runs only briefly and idles the rest of the time.
- Power cut: battery backup safely lowers the car to the floor; it is a safety feature, not normal running.
- Vacuum lifts: use a controlled air release to descend gently when the power is off.
- Reliability: regular servicing keeps the lift efficient and the backup battery dependable.
Frequently asked questions
How much does a home lift cost to run?
Very little. A home lift uses only a small amount of electricity and typically costs a few pounds a month, because it runs for seconds at a time and is idle the rest of the day.
Does a home lift need a special power supply?
Usually not. Many domestic home lifts plug into a standard 13-amp socket and run from an ordinary mains supply, which is part of what makes them straightforward to install.
What happens if the power goes out while I am in the lift?
The battery backup brings the car safely down to the lower floor, so you are not left stranded. It is designed to complete the journey safely rather than to keep the lift running through a long outage.
Can I keep using a home lift during a power cut?
Generally not as normal. The backup battery is a safety feature to lower you to the floor, not a way to run the lift repeatedly. Vacuum lifts can descend gently on a controlled air release.
Does using the lift a lot increase the cost much?
Only slightly. More frequent use and longer journeys between floors use a little more power, but the overall running cost stays low for typical household use.
Keeping the lift reliable is mostly about upkeep. See our guide to home lift maintenance and servicing.
