Other factors affecting the cost of building a retaining wall in the UK


The wall's terrain can highly impact the cost of retaining walls. Depending on the difficulty of the landscape, the final price can increase by 50%, especially if the ground surrounding the wall is sloped. This is because your contractors might need to perform special excavation to terrace the slope. In addition, unstable soil requires extra digging to make it more compact.

Amount of labour

Another factor that goes into the final pricing of retaining walls is labour. If more skilled people are required to work on a single construction project, expect higher costs. The same applies if there's a need to dig out footers and carry blocks. The rule of thumb is that the more complex the job, the higher the cost.

Your location

Expect to pay more if you reside outside your contractor's service area. Additional expenses like gas and parking fees may be considered when your contractor needs to travel from a remote location. To help you stay within your budget, always hire someone within or near your geographical area.

Are retaining walls worth the money?

The answer is yes. Having retaining walls built can be one of the smartest ways to improve your home's landscape. Not only do they make your property more appealing by highlighting your plants and flowers, but they can also extend its overall integrity for years. Retaining walls reduces the likelihood of erosion, as they slow down the flow of water that runs over the surface of your home. In essence, retaining walls are a great combination of beauty and functionality.

FAQs about retaining walls

When it comes to durability, poured concrete is the way to go. It's the strongest material that can withstand wear and tear for years and decades.

It depends on the material you have. On average, retaining walls can last between 25 to 100 years. Solid stone and concrete can last between 50 to 100 years, while retaining walls made of wood have a shorter service life of up to 40 years.

As strong as it is, poured concrete is the cheapest material you can use for retaining walls. That's why it's one of the first go-to options for homeowners who want to build a retaining garden wall.
