Work to refit a bathroom with new units and fittings does not generally require building regulations approval, although drainage or electrical works that form part of the refit may require approval under the building regulations.

Significant changes to insulation and thermal elements would normally require building regulations approval. The extent to which this applies depends on the existing insulation and what it will be replaced with.
