How Much Does It Cost to Knock Down an Internal Wall?
£1,200 – £5,000
per wall
Knocking down an internal wall costs between £1,200 and £5,000, depending on whether the wall is load-bearing, the size of the opening, and how much making-good is required afterwards. A non-load-bearing stud partition is the cheapest to remove; a load-bearing masonry wall requires a structural engineer, a steel RSJ, and temporary propping, which significantly increases the cost.

What affects the price?
Load-bearing vs non-load-bearing - a non-load-bearing stud partition costs £1,200-£2,000 to remove; a load-bearing wall costs £2,500-£5,000+ due to steel beam and structural support requirements
Structural engineer fees - a structural engineer is needed to specify the beam for any load-bearing wall removal, adding £300-£700
Wall material - timber stud walls are quick to remove; solid brick or block walls take longer and produce more rubble
Making good - plastering, flooring, and decorating after the wall comes down is usually a significant additional cost
Labour vs materials
Labour for a straightforward non-load-bearing wall removal takes one to two days. A load-bearing wall removal with steel installation takes two to three days and requires temporary propping while the beam is fitted.
