Key Takeaways
- A stairlift installation is typically quick, taking 1–4 hours depending on whether the staircase is straight or curved.
- The process includes a pre-installation survey, track fitting, chair mounting, safety testing, and a full demonstration.
- Straight stairlifts use modular rails, making installation faster; curved models take longer due to their custom tracks.
- After installation, you can use the stairlift immediately once safety checks are completed.
Short Answer: What happens during a stairlift installation?
A trained engineer visits your home, confirms measurements, installs the rail on your stairs (not the wall), installs the chair, sets up the charging system, runs comprehensive safety tests, and shows you how to operate it. The entire process for a straight stairlift usually takes 1–2 hours, while curved systems may take 2–4 hours.
Step-by-Step Guide: What Happens During a Stairlift Installation
Whether you’re renting or buying, the steps are nearly identical. Here’s exactly what to expect from start to finish.
1. Pre-Installation Survey (Before Installation Day)
Before installation, a surveyor or engineer will assess:
- The shape, width, and pitch of your staircase
- Any curves, landings, or tight turns
- Power outlet location
- Potential obstructions (radiators, handrails, doors)
- Safety considerations like clearance and weight capacity
They take precise measurements to prepare the rail and confirm the correct stairlift model.
For curved staircases:
The rail is custom-made or built using modular sections, which may require a few days before installation.
2. Engineer Arrival and Safety Check (Installation Day)
When the engineer arrives, they will:
- Reconfirm your staircase measurements
- Ensure the area is clear and accessible
- Conduct safety checks
- Protect the flooring if needed
This preparation usually takes 10–15 minutes.
3. Rail Fitting: The Most Important Stage
The stairlift rail is fitted to the staircase, not the wall.
This surprises many homeowners; the rail is secured directly onto the steps using discreet brackets.
What happens during rail fitting:
- Brackets are screwed onto the treads
- Rail sections are attached to the brackets
- The rail is levelled and aligned for a smooth ride
- For straight staircases, this process is very fast
- For curved staircases, alignment takes longer due to the complex geometry
This part typically takes:
- 30–60 minutes (straight staircases)
- 60–120 minutes (curved staircases)
4. Installing the Chair Unit
Once the rail is secure, the engineer:
- Mounts the motor carriage onto the rail
- Fits the seat, armrests, footrest, and safety belt
- Connects remote controls
- Configures the seat’s swivel mechanism
- Checks the folding components for tight spaces
The chair is then run up and down the rail to ensure smooth operation.
5. Setting Up the Charging System
Every stairlift requires a charging point.
The engineer will:
- Position the charge points at the top or bottom of the rail
- Connect the stairlift to its docking charger
- Confirm that the battery charges automatically
No major electrical work is normally needed; a nearby plug socket is usually enough.
6. Full Safety and Performance Testing
Before you use the stairlift, the engineer conducts a comprehensive check, including:
- Start/stop functionality
- Smoothness of travel
- Emergency stop sensors
- Obstruction sensors
- Swivel seat locking
- Remote controls
- Battery charging
- Weight test (if required)
- Track stability and alignment
This ensures the stairlift meets all safety standards.
7. User Demonstration: Learning How to Use It
The engineer will demonstrate how to:
- Safely get seated and fasten the seatbelt
- Start and stop the stairlift
- Use the remote controls
- Fold the seat and footrest
- Operate any optional features (power swivel, hinged rail, etc.)
- Recognise common error beeps or lights.
- Charge the stairlift properly.
They won’t leave until you feel confident using it.
8. Final Clean-Up and Handover
Before leaving, the engineer will:
- Clean up any dust or debris
- Remove packaging
- Check that stairs and carpets are left tidy
- Provide documentation, warranties, or rental agreements
- Give you contact details for future support or repairs
If it’s a rental stairlift, they also confirm how to arrange servicing or removal.
How Long Does Installation Actually Take?
Straight staircases
- 1–2 hours typical
- Fastest installations can be under 1 hour
Curved staircases
- 2–4 hours
- More time is needed due to custom rails and alignment
Outdoor stairlifts
- Similar timings to straight indoor models, depending on weatherproofing requirements
How to Prepare for Stairlift Installation
You don’t need much, but these small steps help:
- Move small furniture or clutter near the stairs
- Ensure pets are out of the way
- Make sure electrical outlets are accessible
- Keep hallways clear for engineers carrying equipment
Most providers handle everything else.
Conclusion
A stairlift installation is straightforward, non-invasive, and completed in just a few hours. The process includes a survey, rail fitting, chair installation, full safety testing, and a user demonstration. Whether you’re renting or buying, the result is the same: safe, reliable access to your entire home from day one.
