Plastering is a skilled trade that creates a smooth, durable finish for your walls and ceilings, ready for decorating. In 2025, the average cost to plaster a medium-sized room in the UK is between £500 and £800. This typically includes skimming the walls and ceiling.
The cost is usually calculated based on the area to be plastered or a day rate. A plasterer's day rate is typically between £150 and £250. A single wall might take half a day, while a full room could take one to two days, depending on its size and condition.
The condition of the existing walls is a key factor. If the walls are in poor condition and require stripping back to the brickwork and applying a new backing coat before skimming, the job will take longer and cost more. Plastering a ceiling is generally more expensive than plastering walls due to the difficulty of working overhead.
Other factors that can increase the price include complex areas like chimney breasts, stairwells, or rooms with many windows and doors, as these require more detailed and time-consuming work.
When getting quotes, confirm whether the price includes materials and waste disposal. It's always a good idea to see examples of a plasterer's previous work to ensure they can deliver the high-quality, smooth finish you're looking for.
