Last updated: June 2026

Assembly & Inspections

Do scaffold towers need regular inspections?

Yes. Scaffold towers should be inspected after assembly, before use, and at suitable intervals by a competent person.

What should I check before using a scaffold tower?

Check braces, guardrails, platforms, castors, stabilisers, trapdoors, and ground conditions before use.

Can anyone build a scaffold tower?

The quick answer is no! To build or erect a scaffold tower safely and correctly, people who are trained competently should only be allowed to do so. People using tower scaffolds, also known as mobile access towers, need to be properly trained in all aspects of erecting, dismantling and working on towers.

Can anyone erect a scaffold tower?

It is essential to ensure that a qualified and licensed mobile scaffolder handles the erection, adjustment, and dismantling of a scaffold tower. This is especially the case if there’s a risk that any person or object could potentially fall four or more meters from either the platform or the structure. But that doesn’t mean anyone can erect if the height is less than 4 meters. This is a guideline, which is why it’s essential to engage a qualified technician for scaffold tower erection.

Common Scaffold Tower Problems

Why does a scaffold tower wobble?

A scaffold tower may wobble if it is not level, incorrectly braced, overloaded, or standing on unstable ground.

Why is my scaffold tower unstable?

Instability is commonly caused by uneven ground, missing braces, unlocked castors, or incorrect assembly.

What should I do if a scaffold tower sinks into the ground?

Stop using the tower immediately and reposition it onto firm, stable ground.

Can scaffold tower wheels fail?

Yes. Damaged or overloaded castors can fail and should be replaced immediately.

What happens if a scaffold tower is overloaded?

Overloading increases the risk of structural failure, instability, and overturning.

DIY vs Trade Towers

Castors may mark delicate surfaces, so floor protection may be required indoors.

Can I use a scaffold tower on a slope?

Most scaffold towers should only be used on level ground unless specifically designed for uneven surfaces.

Can I put bricks or blocks under tower legs?

No. Use proper adjustable legs or base plates only.

What are stabilisers?

Stabilisers are support legs designed to improve tower stability and reduce overturning risk.

Do scaffold towers always need stabilisers?

It depends on tower height, platform length, and configuration. Always follow the manufacturer's instruction manual.

What causes scaffold towers to tip over?

Overreaching, strong wind, uneven ground, unlocked castors, and missing stabilisers can all cause overturning.

Can scaffold towers be used on driveways?

Yes, if the surface is level, stable, and able to support the load safely.

Can you use scaffolding on a slope or uneven ground?

Typical mobile scaffold towers with adjustable wheels are not recommended for surfaces with a slope exceeding 5 degrees. The scaffold tower without flexible components can only be established on level, firm and stable ground, and you need to support the feet or wheels of the tower.

However, scaffold towers with adjustable legs can be used on uneven heights or un-level ground. The supporting components must be adjusted and secured tightly according to the area’s terrain. You must always keep the brakes locked on the wheel unless transporting the system from one site to another.

What scaffold tower is best for uneven ground?

Some scaffold tower systems are designed with adjustable legs or stabilisers for uneven surfaces.

Do scaffold towers need stabilisers?

Many scaffold towers require stabilisers depending on tower height and configuration.

Outdoor scaffold towers should be stable, properly braced, and suitable for external weather conditions.

Ladders

What is an extension ladder?

An extension ladder consists of two or more sliding sections that can be extended and locked into place to reach higher elevations. It is designed to provide access to areas that are out of reach for standard or step ladders. Each sliding section allows the user to adjust the intended working height.

How do you set up an extension ladder?

An extension ladder requires leaning against a wall to support you as you climb. To use it safely, you should ensure the ground is stable, and the ladder is firmly in place.

What is the tallest extension ladder available?

Our tallest extension ladder reaches a height of 10 metres.

What ladder height will I need to reach my gutters?

If you live in a bungalow, in other words, a single-storey home, you can reach your gutters with a 3-metre ladder. 2 or 3-storey houses will require an extension ladder that can reach six or 7-metres or more.

Scaffold Tower Heights

What working height scaffold tower do I need?

Choose a working height that allows safe access without stretching or overreaching.

How is scaffold tower working height calculated?

Working height is usually platform height plus approximately 2 metres.

What scaffold tower height is suitable for a two-storey house?

Most two-storey properties require approximately 6 m to 8 m working height depending on the task.

Can I use a smaller tower and reach higher?

No. Overreaching increases the risk of falls and tower instability.

How high can you build a scaffold tower?

Maximum tower heights depend on the tower system, stabilisers, location, and manufacturer guidance.

How high can a scaffold tower go?

While using a scaffold tower, you always wonder about its maximum height. A scaffold tower built with typical components can achieve a maximum height of around 10 to 12 meters. But many DIYers and even professional tradesmen are confused about the terms “platform height” and “working height.”

Both terms are commonly used in scaffold towers.

The platform height refers to the height at which the platform can be raised. In other words, platform height is the vertical distance between the platform and the ground.

Conversely, working height is the height a person can safely reach while standing on the platform. Scaffold towers are available in various heights from 0.6 meters to 12 meters.

How tall a scaffold tower do I need?

When choosing a scaffold tower, height is also an important consideration, along with many other factors. It would help if you determined the work height to choose the height. To ensure a safe working environment, you must ensure that the worksite is well within the arm’s reach of the working person. A scaffold tower of 6 m and 7 m height works best for most two-story homes as a general guide.

Can I increase or change the height of the scaffold towers?

You can purchase additional sections and components to increase or change the height of your towers. We manufacture and supply every component and part of the equipment. However, we don’t recommend building towers higher than those in the instruction manual. If you need a tower for complex spaces, you need a written risk assessment issued by a competent scaffold tower expert. So, it is best to convey your requirements and buy a tower with the design and parameters which suit your needs better.

What do you mean by “working height” in connection with your scaffold tower sizes? What is the difference between “working height” and “platform height”?

The term “platform height” refers to the height of the tower, i.e., the height at which you can physically stand on it.

“Working height”, on the other hand, is the estimated reach based on the person using the equipment.

The working height is defined as 2 m above the platform height. It is a standard practice in the access industry. This standard will help you to compare different products and get the right one for your needs without engaging in dangerous solutions.

Scaffold Tower Regulations UK

What regulations apply to scaffold towers in the UK?

Scaffold towers used at work must comply with the Work at Height Regulations 2005 and relevant HSE safety guidance.

What is BS EN 1004?

BS EN 1004 is the European standard that applies to mobile access and working towers.

Do scaffold towers need to comply with EN1004?

Yes. Professional mobile scaffold towers used in the UK should comply with BS EN 1004 standards.

Do scaffold towers need inspection tags?

Inspection systems may be required on construction or commercial sites depending on site rules and safety procedures.

Who is responsible for scaffold tower safety on site?

Responsibility usually falls on employers, site managers, supervisors, and competent users.

Scaffold Tower Safety

Can a scaffold tower fall over?

Yes. Scaffold towers can overturn if used on uneven ground, overloaded, exposed to strong wind, or assembled incorrectly.

Can anyone use a scaffold tower?

A tower scaffold can be assembled by a competently trained person after a risk assessment has been done and then signed off. Additionally, a pre-use inspection must be carried out before any person starts to work at a height on the tower.

Can I climb the outside of a scaffold tower?

No. Always use the built-in internal access system.

Can I climb on scaffold tower braces?

No. Braces are structural components and must never be used for climbing.

What are guardrails for?

Guardrails help prevent falls from the working platform and provide collective fall protection.

Are scaffold towers safe?

In short, scaffold towers are safe, but they have maximum load weights like ladders. So, make sure you know that load to ensure the tower doesn’t take more people, equipment, or material to exceed the capacity of the ladder designed to support it.

While equipment and gadgets can be used on the scaffold tower, materials and equipment should not be stored there for long periods. Loading the tower for such can potentially weaken the platform.

Investing in a high-quality scaffold tower is a safer option than buying a cheap one. So, if you are entrusting your life to it, never settle for a budget product.

Although scaffold towers are sturdier and more stable than ladders alone, this doesn’t mean they can tolerate excessive deliberate movements. So, try to limit their exposure to sudden impacts, such as jumping up and down or dropping heavy objects onto them.

What are toeboards for?

Toeboards help prevent tools and materials from falling off the platform.

Do scaffold tower wheels need to be locked?

Yes. Castors should always be locked before anyone climbs or works on the tower.

Can I move a scaffold tower while someone is on it?

No. Remove all people, tools, and materials before moving the tower.

Can I use damaged scaffold tower parts?

No. Never use bent, cracked, broken, or missing components.

Can I mix scaffold tower parts from different manufacturers?

Only use compatible components approved for the specific tower system.

Do you need a harness on the scaffold tower?

So, while you’re a DIYer, you might wonder if falling from the scaffold tower is risky. Well, if you’re using a high-quality scaffold tower with all protection components like guard rails, kickboards, outriggers, and internal ladders, then there’s no need for a harness. Apart from that, you must still follow standard safety requirements like wearing a hard hat, using a high-visibility jacket and keeping tools and materials organised on site.

What is the safest scaffold tower?

A properly assembled aluminium scaffold tower with guardrails, stabilisers, and internal access provides safe working at height.

What is the safest way to use a scaffold tower?

Always follow the manufacturer's assembly instructions and use guardrails, stabilisers, and locked castors.
