What Do You Need to Think of Before Installing a Stairlift?

One of the first questions people ask is whether their staircase is wide enough for a stairlift.

Most stairlifts require a minimum stair width of around 28 inches (70 cm). If your staircase is narrower, don’t worry – slimline stairlifts are available and can be custom-fitted even in tight spaces. A professional installer will take precise measurements to recommend the right solution.

Straight staircases are the simplest and most cost-effective to fit. In many cases, stairlift installation on a straight staircase can be completed in just a few hours. Curved staircases, however, require custom-built rails that follow the bends and turns of your stairs. This makes the installation more complex and typically more expensive, but it ensures a smooth ride that matches your exact staircase layout.

Another important factor is weight capacity. Not all stairlifts are the same, and exceeding the recommended limits can compromise safety.

Most standard stairlifts can carry between 18 and 25 stone (115–160 kg). For heavier users, heavy-duty models are available, offering reinforced seats, rails, and motors. It’s important to choose a stairlift that comfortably accommodates the user’s weight for long-term reliability.

Different brands set their own maximum weight capacities. For example, many Acorn stairlifts are designed for up to 22 stone, while certain Stannah chair lifts can carry up to 25 stone. If multiple family members will use the stairlift, or if you want extra reassurance, it may be worth choosing a model with a higher capacity.

Modern stairlifts come with a variety of built-in features, including seatbelts, swivel seats for easy dismounting, safety sensors to stop the lift if the path is blocked, and battery backup to keep the lift running during a power cut. Of course, these features only remain effective if the stairlift is properly maintained, which is why annual servicing and timely stairlift repairs are strongly recommended.

For straight staircases, stairlift installation generally costs between £2,000 and £3,500. Curved stairlifts are more complex and can range from £4,000 to £6,000 or more, depending on the length and shape of the stairs. Reconditioned stairlifts offer a budget-friendly alternative, with prices starting from around £1,300.

The quoted price typically covers the survey, custom fitting, and standard warranty. However, additional costs may arise if your home requires modifications, such as moving a radiator, or if you choose optional extras like powered swivel seats. Always ask for a detailed quote to avoid surprises.

A stairlift is a long-term investment, so a strong warranty is essential. Most manufacturers include a 12–24 month warranty covering parts and labour. Some providers offer extended warranties at an additional cost, which can be valuable if you want peace of mind for several years.

Once your warranty ends, it’s often smarter to consider independent stairlift installers. The reasons are clear: independent companies usually offer:

• more competitive pricing;
• faster response times;
• personalised service compared to national providers. 

Even if your warranty is still active, choosing a local expert like TJ Services can be the right move when speed matters most, as we can often attend call-outs and carry out stairlift repairs much quicker than manufacturer engineers.

Manufacturers recommend servicing a stairlift once a year. This inspection helps prevent costly breakdowns and ensures safety features continue to work as intended.

Common issues that require stairlift repairs include worn batteries, motor problems, or track obstructions. These are often simple to fix but should never be ignored, as delaying repairs can compromise safety. 

Selecting the right provider is just as crucial as choosing the right stairlift. A professional, experienced company will not only ensure the stairlift fits your staircase perfectly but will also provide long-term support, clear warranties, and fair pricing. When choosing, look for companies with strong local reputations, transparent quotes, and quick response times. Reading customer reviews and asking about aftercare services will also help you make a confident decision.
