Key Takeaways
- A straight stairlift typically takes 1–2 hours to install.
- A curved stairlift usually takes 2–4 hours because the rail is custom-made and requires precise alignment.
- Pre-installation surveys and custom rail manufacturing (for curved models) add extra time before installation day.
- After installation, you can use the stairlift immediately once safety tests are complete.
Short Answer: How long does installation take?
A straight stairlift can be installed in around 1–2 hours.
A curved stairlift normally takes 2–4 hours due to complex track fitting.
The total project timeline may be longer for curved staircases because the track must be manufactured after the survey.
How Long Does Stairlift Installation Take?
Installation speed depends on staircase type, rail design, and the complexity of your home layout. Here’s a breakdown of what to expect.
Straight Stairlift Installation Time (1–2 Hours)
Straight stairlifts use modular, pre-made rails, making installation fast and predictable.
Typical timeline on installation day:
- 10–15 minutes: Engineer arrives, double-checks measurements
- 30–60 minutes: Rail fitted to the stairs
- 20–30 minutes: Chair unit installed and tested
- 10–15 minutes: Safety checks and user demonstration
Why straight stairlifts are quicker:
- No custom rail required
- Simpler alignment
- Fewer obstacles
- Stock parts are available immediately
Straight stairlifts are the fastest option and can often be installed within 24–72 hours of the initial survey, sometimes even the same day.
Curved Stairlift Installation Time (2–4 Hours)
Curved staircases require made-to-measure rails, which adds complexity both before and during installation.
Typical timeline on installation day:
- 10–15 minutes: Setup and staircase preparation
- 1–2 hours: Custom rail installation and alignment
- 45–60 minutes: Carriage, seat, and safety systems installed
- 20–30 minutes: Full testing and demonstration
Why curved stairlifts take longer:
- The rail must match unique bends, landings, and turns
- Alignment and levelling are more precise
- Additional brackets and fittings are often required
- The engineer must test each curve for smooth travel
Although the installation itself takes only a few hours, curved stairlifts usually require extra lead time because the manufacturer must produce the rail after the survey.
Lead Times: Straight vs Curved Stairlifts
Installation day is quick, but the overall timeline depends on the staircase type.
Straight stairlifts:
- Ready in 1–3 days (survey + installation)
- Many providers offer same-day installation
Curved stairlifts:
- Ready in 5–14 days, depending on the provider
- Some offer fast-track modular rails for quicker turnaround
Most delays come from rail fabrication, not the installation itself.
Factors That Can Affect Installation Time
1. Staircase Complexity
Narrow, steep, or spiral stairs take longer.
2. Power Supply Location
If a socket needs relocating, it may add extra time.
3. Obstacles on the Stairs
Radiators, doors, and handrails may require adjustments.
4. Optional Features
Power swivel seats, hinged rails, or outdoor weatherproofing can extend installation time.
5. Multiple Floors or Landings
Multi-flight staircases need additional rail sections and safety testing.
How to Prepare for a Faster Installation
- Clear the hallway and staircase area
- Ensure pets are kept away
- Provide easy access to a plug socket
- Move small furniture or obstacles
- Be available to answer questions
These small steps help engineers work quickly and safely.
Conclusion
Installing a stairlift is a quick, efficient process.
- Straight stairlift: 1–2 hours
- Curved stairlift: 2–4 hours
Although curved models take longer due to custom rail fitting, both types allow you to use the stairlift immediately after installation. With proper preparation and a reliable provider, most installations are completed in a single visit with minimal disruption.
