Stairlift Installation in the UK
How the installation works, how long it takes, and what affects the costStairlift installation is usually quicker and less disruptive than people expect. In most homes, a stairlift can be fitted without structural changes, planning permission, or major electrical work. However, installation time and cost vary depending on the staircase and the type of stairlift being fitted.
This guide explains how stairlift installation works, what preparation is required, and what can delay installation.

How stairlift installation works
A standard stairlift installation typically involves:
- Measuring the staircase
- Fitting the rail to the stair treads
- Installing the chair and motor unit
- Testing safety features and controls
Most stairlifts plug into a standard socket and do not require new wiring. A full step-by-step explanation is available in stairlift installation step by step.
How long does stairlift installation take?
Installation time depends mainly on whether the stairlift is straight or curved.
- Straight stairlifts are usually installed in a few hours
- Curved stairlifts take longer due to custom rails and more complex fitting
Typical timeframes are explained in detail in stairlift installation time and broken down further in curved installation timelines.
In some cases, same-day installation is possible, which we explain in same-day stairlift installation.
What affects stairlift installation cost?
Installation cost is influenced by several practical factors, including:
- Staircase shape and length
- Number of turns or landings
- Access and working space
- Stairlift type and weight capacity
Common causes of delays and added costs are covered in stairlift installation problems.
Is a home survey required?
Yes. A home survey is usually carried out before installation to ensure the stairlift is suitable and safe.
The survey checks:
- Stair width and layout
- Fixing points
- Power supply location
- User needs
We explain what happens during this visit in initial stairlift survey.
Do you need planning permission for a stairlift?
In most UK homes, planning permission is not required for stairlift installation because stairlifts are classed as internal mobility aids.
There are exceptions, such as listed buildings or external installations. We explain these cases in planning permission for stairlifts.
Electrical requirements for stairlifts
Most stairlifts run on rechargeable batteries and charge from a standard plug socket.
Installation usually does not require:
- New circuits
- Consumer unit upgrades
- Major electrical work
However, access to a socket is required. We explain this in stairlift electrical requirements.
Preparing your home for installation
Basic preparation helps the installation run smoothly. This usually includes:
- Clearing the staircase
- Removing loose rugs or obstructions
- Ensuring access to plug sockets
A practical checklist is available in stairlift installation preparation checklist.
Can you install a stairlift yourself?
DIY stairlift installation is strongly discouraged. Stairlifts are heavy, require precise alignment, and involve safety-critical components.
Attempting DIY installation can:
- Void warranties
- Create safety risks
- It costs more to correct later
We explain the risks in DIY stairlift installation.
Installing stairlifts in rented homes
Stairlifts can often be installed in rented properties, but landlord permission is usually required.
Responsibilities for installation and removal should be agreed in advance. We explain considerations in stairlifts in rented homes.
What happens after installation?
After fitting, the installer should:
- Demonstrate safe operation
- Explain charging and controls
- Test emergency stop features
- Answer usage questions
Ongoing reliability depends partly on maintenance, as explained in stairlift servicing.
