What affects the cost?

Checkatrade’s June 2026 whole-house benchmark for an average 3-bedroom property is £43,530–£110,350, averaging £76,690. The range is wide because one renovation may be largely cosmetic while another includes heating, rewiring, plastering, windows, a kitchen, structural work, damp treatment and roof replacement.
