Werner Stabiliser Kit (AC30)
Best OverallPros
- Very wide stand-off for excellent stability
- Universal fit for most ladder types
- Durable steel build with anti-slip pads
Cons
- Heavier than some aluminium options
- May be overkill for lightweight step ladders
The Werner AC30 is the gold standard for ladder stabilisers under £150. Its 760mm stand-off width is one of the widest available, providing a huge safety margin against sideways movement. The steel construction feels solid and the rubber pads protect gutters from damage.
Owner reviews consistently praise its ease of fitting and the peace of mind it provides on uneven ground. It works with most extension ladders up to 120mm wide, making it a versatile and reliable choice for professionals and serious DIYers alike.
Sealey Ladder Stay (LS01)
Best BudgetPros
- Excellent value for money
- Solid steel construction
- Simple to install and remove
Cons
- Narrower stand-off than the Werner
- Rubber pads could be thicker
The Sealey LS01 is a fantastic budget-friendly stabiliser that doesn't compromise on core safety features. It offers a 600mm stand-off width, which is still a significant improvement over using a ladder without one. The steel frame is robust and the fixing mechanism is straightforward.
User reviews highlight its reliability and how it makes ladder work feel much more secure. While it's not as wide as the Werner, it's more than adequate for most domestic tasks like gutter cleaning and painting. It's a smart choice for the price-conscious buyer.
Draper Ladder Stabiliser (DLS700)
Best for Heavy DutyPros
- Very robust heavy-duty steel frame
- Wide 700mm stand-off
- Thick rubber bumpers for gutter protection
Cons
- Heaviest option on the list
- May be too bulky for storage
For those who need maximum durability, the Draper DLS700 is a top contender. It's built with a thicker gauge steel than many competitors, giving it an exceptionally solid feel. The 700mm stand-off provides a generous safety margin, and the rubber bumpers are thick and durable.
This stabiliser is ideal for frequent use on construction sites or for very tall ladders where stability is paramount. Owner reviews often mention its reassuring strength and how it handles heavy loads without flexing. It's a premium choice for heavy-duty applications.
Stanley Ladder Stabiliser (STST1-70314)
Best for VersatilityPros
- Lightweight hybrid construction
- Adjustable stand-off arms
- Good balance of weight and strength
Cons
- Not as wide as the top picks
- Some plastic components in the locking mechanism
The Stanley stabiliser stands out for its versatility and lighter weight. It uses a combination of aluminium and steel to keep the weight down to 1.8kg, making it easier to carry and fit. The stand-off arms are adjustable, which adds flexibility for different working angles.
This model is a great middle-ground option. It's lighter than the all-steel models but still offers a solid 650mm stand-off. Owner reviews appreciate its ease of use and how it doesn't add excessive weight to the ladder. It's a good choice for DIYers who need a practical, everyday stabiliser.
Bahco Ladder Stay (BLS-1)
Best for LightweightPros
- Very lightweight at 1.2 kg
- Compact and easy to store
- Good for lighter duty tasks
Cons
- Narrowest stand-off width
- Not suitable for heavy-duty use
The Bahco BLS-1 is the lightest stabiliser on our list, made entirely from aluminium. It weighs just 1.2kg, so it barely adds any noticeable weight to your ladder. It's perfect for quick jobs where portability is key, such as changing light bulbs or cleaning windows.
While its 550mm stand-off is narrower than others, it still provides a meaningful improvement in stability compared to using a ladder without one. Owner reviews highlight its convenience and how easy it is to carry around. It's a specialist tool for those who prioritise minimal weight and compact storage.
What to check before buying a ladder stabiliser
Stand-off width: This is the distance the stabiliser pushes the ladder away from the wall. A wider stand-off (700mm+) provides better stability and protects gutters, but it also changes the working angle. Ensure it's compatible with your ladder's intended use.
Ladder width compatibility: Check the maximum ladder rail width the stabiliser can accommodate. Most models fit standard 100-120mm rails, but always verify your ladder's dimensions before purchase.
Material and weight: Steel stabilisers are more durable but heavier. Aluminium models are lighter and easier to carry but may not be as robust for heavy-duty professional use. Consider how often you will be moving the stabiliser.
Build quality and warranty: Look for a stabiliser with thick rubber bumpers to protect walls and gutters. A longer warranty (often 1-2 years from brands like Werner and Draper) is a good indicator of build confidence.
Mistakes to avoid when buying a ladder stabiliser
Buying the cheapest option: Very cheap stabilisers may have poor build quality, thin rubber pads, or unreliable locking mechanisms. A low price can lead to a false sense of security. Stick to reputable brands like Werner, Sealey, and Draper.
Ignoring ladder compatibility: Not all stabilisers fit all ladders. Measure your ladder's rail width and check the stabiliser's maximum width. A stabiliser that is too loose or too tight can be dangerous.
Overlooking weight: A heavy stabiliser can make your ladder top-heavy and harder to manoeuvre. Balance the need for a wide stand-off with the practicality of carrying and fitting the unit, especially if you work at height regularly.
FAQs
What does a ladder stabiliser do?
A ladder stabiliser attaches to the top of your ladder to widen its contact point with the wall, preventing sideways slips and protecting gutters from damage.
Are ladder stabilisers universal?
Most are designed to fit a range of standard ladder widths, but you must check the maximum rail width specification. The Werner AC30 is one of the most universal options.
Can I use a stabiliser on a step ladder?
No, ladder stabilisers are designed for extension ladders. Using one on a step ladder would be unsafe as it could alter the ladder's centre of gravity.
How wide should a ladder stabiliser be?
A stand-off width of 600mm is a good minimum for most tasks. For maximum safety, especially on uneven ground, look for 700mm or more like the Werner AC30.
Is a ladder stabiliser worth the money?

How do I fit a ladder stabiliser?
Most models use a simple clamp or bolt-on system that attaches to the top two rungs of your extension ladder. Always follow the manufacturer's instructions for a secure fit.
Will a stabiliser damage my gutters?
No, a good stabiliser is designed with rubber bumpers that spread the load and prevent damage to gutters and fascia boards. The Werner and Draper models have excellent pads.
What is the best brand for ladder stabilisers?
Werner is widely regarded as the best brand for ladder stabilisers, known for their robust build and wide stand-off. Draper and Sealey are also very reliable choices.
Can I leave a stabiliser on my ladder?
Yes, most stabilisers are designed to be left attached to the ladder. However, they can add weight and bulk, making storage more difficult.
Are aluminium or steel stabilisers better?
Steel is stronger and more durable, while aluminium is lighter and easier to carry. Choose steel for heavy-duty use and aluminium for portability.
