Common questions
How much does structural work cost in the UK?
Across 1 real prices people actually paid, the median is £2,300, ranging from £2,300 to £2,300. These are real prices homeowners posted, not cost-guide estimates.
Why do structural work prices vary so much?
Size, spec, region and the individual trade all move the figure, and cost guides rarely say which. Seeing what real people paid, with the details they shared, gives you a far better benchmark than a single average.
Are these structural work prices quotes or actual bills?
Actual bills. We deliberately exclude quotes and estimates and only publish amounts people said they paid, each linked to the original post.
