The cost of a polished concrete floor in the UK can vary depending on the size of the area, the level of preparation required, and the finish desired.
On average, you can expect to pay between £120 to £150 per square metre for a polished concrete floor. However, the cost can be higher or lower depending on the factors mentioned above.
It's important to note that the cost may also include additional expenses such as site preparation, grinding, polishing, and sealing. You should also factor in any additional costs for decorative options such as staining or engraving.
As with any home improvement project, it's always best to get quotes from multiple contractors to compare prices and services offered. Additionally, you may want to consider the reputation and experience of the contractor to ensure quality workmanship and customer satisfaction.
