Contaminated land report in Wales
43 providers offering contaminated land report in or across Wales, including national firms. The rules in Wales differ from England’s, so see the notes below.
The rules in Wales
In Wales the local planning authority decides, and Natural Resources Wales advises it on risks to the water environment. NRW points developers to the same LCRM guidance, so the staged approach is the same. Check the council’s validation requirements.

Contaminated land report in Wales
This page lists geoenvironmental consultants covering all 22 Welsh local authority areas, with cities such as Cardiff, Swansea, Newport and Wrexham. Each of the 22 councils is the planning authority for its area, and Wales sets its own planning policy, so check the rules for Wales rather than England.
We list 12 firms for contaminated land report in Wales. Of these, 2 work only in this region and 10 also cover other regions. Another 31 firms say they cover the whole UK.
Firms that work only here are based in Abergavenny (1) and Taff's Well (1).
Of the 12, 4 state an accreditation or membership. We have not verified any of them yet, so these are as each firm states. See how we check listings.
Nearby regions for contaminated land report: South West, West Midlands and North West. Other reports in Wales: flood risk assessment, biodiversity net gain assessment, structural engineer’s report, topographical survey and drainage strategy (SuDS).
Getting signed off in Wales
Building control in Wales works much like England. Your council or a registered building control approver checks the work and issues a completion or final certificate. Wales has its own Approved Documents, and all new and converted homes must have sprinklers.
