Key Takeaways
- A stairlift typically uses £2–£5 of electricity per month in the UK.
- Annual running costs are usually £20–£60, depending on usage and model.
- Stairlifts are energy-efficient because they run on low-voltage rechargeable batteries rather than mains power.
- Most electricity consumption comes from charging the batteries, not actual travel.
- Usage patterns, battery condition, and rail type (straight vs curved) can slightly change monthly costs.
How Much Electricity Does a Stairlift Use Each Month?
The average UK stairlift costs £2–£5 per month to run, often less than a kettle or a television.
This is because stairlifts use two rechargeable batteries that charge slowly and efficiently while the lift is parked.
The motor only draws battery power when moving, and each journey uses very little energy.
Why Stairlifts Use So Little Electricity
1. Low-voltage battery operation
Most stairlifts run on 24V DC batteries, which consume much less energy than mains-powered appliances.
2. Efficient charging system
Charging happens gradually and automatically when the stairlift is parked at its charging point.
3. Short travel times
An average trip lasts 20–30 seconds, meaning daily usage is minimal.
4. Smart energy controls
Modern stairlifts stop charging once batteries are full, reducing unnecessary power use.
Electricity Usage Breakdown
| Factor | Typical Consumption | Monthly Cost Impact |
| Charging the batteries | ~90–95% of total energy | Main cost driver |
| Motor usage when moving | Minimal | Only pennies |
| Standby mode | Very low | Negligible |
Cost by Stairlift Type
Straight Stairlifts
- Monthly cost: £2–£4
- Simple travel path = the lowest energy usage.
Curved Stairlifts
- Monthly cost: £3–£5
- Slightly higher usage due to longer travel paths and extra motor torque around bends.
Standing / Perch Stairlifts
- Monthly cost: £2–£4
- Similar to straight seated lifts.
Outdoor Stairlifts
- Monthly cost: £3–£6
- Cold weather slightly reduces battery efficiency, increasing charging time.
How Many Units of Electricity Does a Stairlift Use?
A stairlift uses around:
- 20–40 kWh per year, depending on model and usage.
At average UK electricity prices, this equals:
- £20–£60 per year
- £2–£5 per month
This makes stairlifts among the lowest-cost mobility aids to operate.
Factors That Affect Electricity Use
1. Frequency of use
More trips = more charging cycles.
However, even heavy use rarely exceeds £6 per month.
2. Battery age and condition
Old or failing batteries charge less efficiently and use more electricity.
Fresh batteries reduce running costs.
3. Staircase length and gradient
Long or steep staircases require more power per trip.
4. Cold environments
Outdoor lifts use more power to maintain battery performance.
5. Curved rails
Bends require additional torque → slightly more energy.
How to Reduce Stairlift Electricity Costs
Keep the stairlift parked at its charging point
Avoids unnecessary deep charging cycles.
Replace ageing batteries
New batteries are more energy-efficient.
Keep the rail clean
Smooth travel reduces motor load.
Regular servicing
Ensures the lift runs efficiently and quietly.
Avoid blocking the track.
Obstructions cause the motor to work harder.
Do Stairlifts Increase Your Electricity Bill Significantly?
No.
Stairlifts are among the most energy-efficient mobility devices available.
To put it into perspective:
| Appliance | Typical Monthly Cost | Comparison |
| Stairlift | £2–£5 | Very low |
| Kettle | £4–£10 | Higher |
| TV | £4–£8 | Higher |
| Electric heater | £30–£80 | Much higher |
| Washing machine | £4–£6 | Higher |
A stairlift typically costs less than a cup of coffee per month to run.
Bottom Line
A stairlift uses very little electricity, usually £2–£5 per month, thanks to its battery-powered design and efficient charging system. Even heavy users rarely exceed £6 per month.
This makes stairlifts among the most affordable mobility aids to operate, offering independence at a very low operating cost.
