New ‘building work’ must comply with Building Regulations and includes:
* installation of a service, e.g. washing or sanitary facilities
* material alterations to the structure
* conversions to flats
* some major repairs.
Hanlet v Tameside Metropolitan Borough Council [2010] UKUT 351 (LC). Suppose something complies with building regulations (or could easily be made to comply). In that case, this is a “material consideration” for a tribunal about a housing health and safety rating system (HHSRS) case.
