Lifts have a habit of running up costs quietly. They sit in the background of a building, working away day and night, and the energy they consume rarely gets the scrutiny applied to heating or lighting. Yet an older lift can be surprisingly hungry, and a great deal of that consumption happens when the lift is not even moving. With energy prices a constant concern for facilities managers and building owners, the running cost of a lift deserves a closer look. Modern technology has changed what a lift costs to keep going, and several upgrades pay for themselves over time. Here is where the savings come from.
Standby consumption is often the biggest culprit

It surprises many building owners to learn that a large share of a lift’s total energy use can happen while it sits completely idle. Older controllers, lighting, displays and ventilation can draw power continuously, even through the small hours when the lift carries nobody at all. Because a lift spends far more of its life waiting than moving, this standby draw adds up to a significant figure over the course of a year.
Bringing standby consumption down is often the most effective efficiency improvement available. Modern control systems can power down non-essential components when the lift is not in use and wake them the moment a call is registered. For a lift that stands idle for long stretches overnight and at weekends, the saving from tackling standby alone can be substantial, and it changes nothing about how the lift behaves when someone needs it.
LED lighting in the car
Lift car lighting is often left on permanently, which makes it one of the easiest wins available. Swapping older lamps for LED units cuts the energy used for lighting sharply, and the LEDs themselves last far longer, which reduces both replacement costs and the number of maintenance visits spent simply changing bulbs.
Pair LED lighting with a sensor that dims or switches the lights off when the car is empty, and the savings grow further, with no impact on the passenger experience. It is a small upgrade with a quick payback, and one of the simplest improvements to retrofit to an existing lift without significant downtime. Better lighting also makes the car more pleasant to use.
Regenerative drives
Regenerative drives are among the more rewarding upgrades for a busy lift. A regenerative drive captures the energy generated when a lift brakes, for example when a heavily loaded car descends or a lightly loaded car rises, and feeds it back into the building’s electrical supply instead of wasting it as heat.
In a frequently used lift, the energy recovered over a year can be considerable. There is a useful secondary benefit too. Because the drive is no longer dumping that energy as heat, the machine room runs cooler, which can reduce or even remove the need for separate cooling and save energy a second time over. For high-traffic lifts in offices, hospitals and busy public buildings, a regenerative drive is among the strongest upgrades available, and the busier the lift, the faster it pays for itself.
Efficient motors and machine room-less designs
Older lifts often rely on geared traction machines or hydraulic systems that are markedly less efficient than modern alternatives. Gearless and machine room-less designs tend to use less energy, run more smoothly and quietly, and take up less space within the building.
Replacing the drive system is a bigger step than changing a few light fittings, but it can transform both the running cost and the ride quality of a lift. Where an ageing, inefficient drive is already causing reliability problems, upgrading it solves two issues at once, improving dependability while cutting consumption. Hydraulic lifts in particular can be heavy users of energy, so for those the case for a more modern drive is often especially strong.
Smart controls and traffic management
In buildings with more than one lift, intelligent control systems make a clear difference. By grouping calls efficiently, they ensure that cars travel fewer unnecessary journeys, which means less energy used and less wear on the equipment. A well-managed bank of lifts does less pointless travelling, sending the nearest suitable car rather than whichever happens to respond first.
Even on a single lift, a well-configured controller with a genuine sleep mode avoids needless activity during quiet periods. The lift does only the work it needs to do, and the energy bill reflects that. These gains come purely from smarter software and control, without touching the mechanical parts of the lift at all.
Knowing where your energy goes
Before spending anything, it helps to understand where a particular lift uses its energy, because the answer varies by lift. A lift that runs almost constantly in a busy building will benefit most from a regenerative drive and efficient motor, where the gains come from all that movement. A lift that sits quiet for long periods, by contrast, will save most from tackling standby draw and lighting, since that is where the bulk of its consumption hides.
An experienced engineer can look at how a lift is used and point to the upgrades that will repay themselves fastest, rather than fitting everything regardless. That matters, because the right improvement on a busy lift may be the wrong priority on a quiet one. Spending where the savings are, in the order that makes sense, is what turns efficiency work from a cost into an investment that pays you back.
It also helps to remember that lower energy use is not only about the monthly bill. For many commercial owners, cutting a building’s consumption feeds into wider reporting on carbon and running costs, and a lift is one of the few pieces of plant that runs continuously, day and night, all year round. Trimming its draw contributes to those targets while quietly reducing what you spend. That dual benefit often makes the case for efficiency work far easier to put to a board, a landlord or a finance team, particularly when the upgrades can be shown to pay for themselves within a few years. Framing the conversation around payback rather than outlay tends to win the argument.
Build the savings into your next refurbishment
You do not have to replace an entire lift to enjoy these benefits. Many efficiency upgrades, including LED lighting, modern controls and in some cases a regenerative drive, can be fitted as part of a refurbishment. If you are already considering modernising an ageing lift, that is the moment to specify efficiency improvements at the same time, since much of the access and disruption is happening anyway.
