Breeze block wall cost

The average cost of breeze blocks per m² (includes £3 per m² for mortar) is £17.50 (supply only).

So far, so good. But here's the thing to know. The labour time and foundations needed can also affect your breeze block wall price.

Let's work out the costs involved for a clearer picture.

Breeze block garden wall cost

On average, the cost of a breeze block garden wall (supply & build) should come in at between £50 and £65 per m².

However, the cost of building a breeze block garden wall depends on the block type and whether or not you need planning permission. You'll also need to consider access, the shape of the wall and the cost of waste disposal.

Let's look at each of these factors in a little more detail:

1. Breeze block retaining wall:

• If you're building a low, freestanding wall below 60cm tall for decorative purposes, a small trench will secure your breeze block wall footing

• However, for taller retaining walls (holding back soil) or load-bearing walls (i.e, to support a garage), you'll need deeper foundations built

• The average cost to build foundations for a retaining wall is around £195 m² (don't forget to add on the cost of the breeze blocks, too)

2. Waste removal:

• Depending on what’s already there (i.e. an existing wall or fence), you could need to hire a skip

• Skip hire prices range from £75 to £450 per week, depending on the size of the skip you need

3. Planning permission:

• If your planned garden wall is above a metre high and located next to a road or public pathway, it's likely that you'll need to seek planning permission

• Our planning permission price guide runs you through the costs involved

4. Rendering:

• Bare unrendered blocks are more susceptible to weathering, so finishing the wall with render or cladding will protect it and extend its lifespan

• Rendering per m² costs on average £39

5. Buying breezeblocks direct:

• Some homeowners choose to purchase blocks directly and use a labour-only bricklayer

• Your labour cost per m² is on average £40

• Alternatively, budget £240–£320 per day for a bricklayer

Other factors that can affect your breeze block wall cost

The cost of a breeze block wall depends on a number of factors, including:

• The length, height, thickness, and shape of the wall (as curves and corners usually add to the cost)

• The type and style of breeze blocks (dense blockwork bricks work out cheaper than hollow decorative breeze blocks)

• Prep work (such as excavation or levelling the ground, if needed)

• Access (if carting materials, waste and equipment through to the site is difficult, you can expect it to take longer and cost more)

• Finish (cladding, paint or render is an additional cost)

• Your location (costs may be higher in London and parts of the South East due to demand)

Breeze block wall cost: By size and type

A standard UK breeze block measures 440mm × 215mm × 100mm (length × height × depth), though you'll also find 140mm and 215mm-depth versions for thicker walls.

Here's the common type of breeze blocks:

• Standard solid dense (7N): Used for thicker structural walls, such as garden walls and retaining walls

• Hollow & cellular: Usual for partition screens and decorative features

• Lightweight/aircrete: Usual for internal partition walls

Breeze block vs brick wall: what's the difference in cost?

Wondering if breeze block is cheaper than brick?

A breeze block wall typically costs £57.50 per m² (materials and labour) vs £150 per m² for a single skin brick wall (materials and labour). So blocks are usually the cheaper option for functional garden structures.

That said, breeze blocks are quite different from ordinary bricks and aren't suitable for all building jobs. Here's why:

• They're made of concrete, whereas bricks are made of clay

• Breeze blocks are much larger and are hollow in the middle

• Breeze blocks aren't suitable for load-bearing structural work (unlike bricks), but are great for gardens and outside structures

How long does it take to build a breeze block wall?

Building a standard breeze block garden wall typically takes a bricklayer one to three days for a 10m run at standard fence height (around 1.8m).

That said, curved walls, retaining structures, or jobs needing ground levelling and new footings will take longer.

Contact an experienced bricklayer, and they'll give you a firmer timeline when they quote.

• Supply and installation of the breeze blocks and mortar

FAQs

What's the difference between a breeze block wall and a brick wall?

Breeze blocks are quite different from ordinary bricks. They're made of concrete, whereas bricks are made of clay. Plus, breeze blocks are much larger and are hollow in the middle. This is why they're not really suitable for load-bearing structural work, unlike bricks. However, they're great for gardens and outside structures.

Is breeze block cheaper than brick?

A breeze block wall typically costs £57.50 per m² (materials and labour) vs £150 per m² for a single skin brick wall (materials and labour). So, breeze blocks are usually the cheaper option for functional garden structures. Breeze blocks are also quicker to lay, which is why they're popular for functional garden walls, screens and outbuildings.

What's the difference between a breeze block and a cinder block?

In everyday UK use, the terms 'breeze block' and 'cinder block' are interchangeable, but both refer to standard concrete masonry units. Cinder block is more common in the US and originally referred to blocks made with coal cinders, whereas modern UK breeze blocks are made from aggregate concrete.

Do breeze blocks need foundations?

Yes, any wall over about 600mm tall should usually sit on a concrete strip foundation. For a standard garden wall, expect a foundation around 450mm deep and 300mm wide. Your builder can advise based on the soil type and wall height.

How many breeze blocks do I need per m²?

Standard 440 × 215mm blocks cover roughly 0.09m² each, so you need approximately 10 blocks per m² of wall face. Add 5–10% for cutting waste, especially if the wall has corners or curves.

How long does a breeze block wall last?

A well-built, rendered breeze block wall can last 50 years or more with basic maintenance.
