The cost of ready-mix concrete in the UK can vary depending on several factors, such as the grade and quantity of the concrete, the distance to the delivery site, and any additional services or materials required for the project.
On average, the cost of ready-mix concrete can range from £65 to £105 per cubic meter. This means that for a concrete slab that is 10 meters long, 4 meters wide, and 0.1 meters deep, which equates to 4 cubic meters in total, the cost of ready-mix concrete could range from £280 to £400.
However, it's important to note that these are just rough estimates and the final cost may vary depending on the specific requirements of your project. Other factors that may affect the cost include the complexity of the project, the timing of the delivery, and any additional charges for weekend or evening delivery.
To get a more accurate cost estimate for your specific project, it's best to get quotes from multiple ready-mix concrete suppliers and compare them.
