The Enviro All-in-One is the UK’s FIRST and ONLY combined CON29M mining and environmental search brought to you by the Coal Authority and Groundsure

The enhanced Enviro All-in-One is a fully integrated residential environmental risk report. It is the only available report to combine the official CON29M coal mining search with flood, contaminated land, ground stability and radon searches. It also screens other environmental risks such as energy installations, transportation and planning applications.

The expert way to search

  • The UK’s only report combining CON29M mining search and environmental searches. Answers all the approved Law Society coal mining questions – including findings on past, present and future coal mining
  • Brought to you by Groundsure and the leading authority on coal mining: The Coal Authority
  • Flood risk assessment now includes new JBA 5m groundwater data – detailing all sources of flood including groundwater and surface water risk. Also reviews historical flood events & proposed flood defence schemes
  • Enhanced view on potential and planned energy installations – the energy screening details specific energy infrastructure categories within 5km of the property. This alert includes existing and proposed: oil and gas sites including fracking; power stations including nuclear; wind power projects; solar farms and major energy infrastructure projects
  • Enhanced transportation summary – provides detail on HS2 (route, safeguarding, stations & depots); Crossrail 1 (route, stations, worksites); Railways (active railways, stations), Docklands Light Railway
  • Enhanced screening on planning applications
  • Enhanced visual and cultural designations – e.g. building conservation areas, listed buildings.

Why does Enviro All-in-One work harder for you and keep your transactions moving faster?

Improved accuracy

  • Uses Land Registry polygons – improving the accuracy of site plans and associated detail
  • A buffer zone of 20m is included within the report for recorded mine entries to satisfy what the Law Society, the Royal Institute of Chartered Surveyors, the Council of Mortgage Lenders and the Association of British Insurers deems an appropriate distance when evaluating risk.
  • The Coal Authority’s unique GIS database is updated every 24 hours by in-house experts as new hazards and cases of subsidence are reported
  • Residential reports are measured 0-15 hectares (on coalfield only)


An insurance policy is included in the Residential Enviro All-in-One covering £50,000 reduction in property value if there is a change in information. Insurance is covered by Liberty Legal Indemnities.

The most accurate database for storage tanks, energy features and military installations
  • Environmental Permits, Incidents and Registers
  • Active and historical landfill data from authoritative sources, including the Environment Agency, British Geological Survey (BGS), Local Authorities and historical Ordnance Survey mapping
  • Current industrial site data
  • Ofcom mobile phone mast information – locations & planning applications relating to phone masts
  • Potentially infilled land
  • Historic military and ordnance sites
  • Designated environmentally sensitive sites including Green Belt, Local Nature Reserves and National Parks
  • Ground stability assessment including non-coal mining and subsidence risks
  • Detailed radon potential data
  • JBA Floodability Rating & Flood Re statement

* Reliance: For those parts of this report that include Groundsure’s data, Groundsure has Professional Indemnity Insurance (any one claim) and that part of the report can be relied upon by all professional parties within a property transaction, first purchasers / tenants and their advisers. Please refer to Groundsure terms & conditions.

What is radon?

Radon is a naturally occurring radioactive gas, produced by the radioactive decay of Uranium (238U). Uranium is found in small quantities in all soils and rocks throughout the UK. It is not possible to see or smell radon and specialist equipment is required to detect it. Click here for more information about radon

What is natural ground subsidence?

Natural ground subsidence refers to the upward, lateral or downward movement of the ground that can be caused by a range of natural geological hazards, such movements are typically in the order of centimetres, but exceptional circumstances can be larger. Significant natural ground instability has the potential to cause subsidence damage to some weaker buildings and structures. Click here for more information about subsidence

What does 'Passed/Acceptable Environmental Risk' mean?

Groundsure provide a statement regarding the likely designation of the property under Part 2A of EPA 1990 and the level of risk associated with the property represents either ‘Acceptable Environmental Risk’ or ‘In Need of Further Assessment’ ‘Acceptable Environmental Risk’ or ‘Passed’ indicates that there is an unlikely risk of statutory (Part 2A EPA 1990) or third party action being taken against the site and the potential environmental risks associated with the property are not considered significant

What does 'In Need of Further Assessment' mean?

In Need of Further Assessment does not necessarily mean that the site is unsuitable for purchase, but only that further assessment of the risk associated with the site is required. When a site is ‘In Need of Further Assessment’ then the practitioner may, if required, discuss the case with one of the Groundsure Consultants.

CON29 Local Authority Searches

The CON29, Section 3.12 of The Local Authority Search is an identification of land that has already been designated as “contaminated land” under Part 2A of the Environmental Protection Act 1990. This doesn’t provide an indication if a site is on the local authority’s Contaminated Land Inspection Strategy or if it is likely to be designated.
