as standard.

Mirrored CON29M Report

The CON29M Report is an official Law Society legal search form used when buying and selling domestic properties within coal mining reporting zones.

Terrafirma were the first commercial organisation to be licensed as a report producer by The Law Society, enabling us to provide a new and enhanced official CON29M report.

The Terrafirma CON29M answers all official CON29M questions on coal mining and combines all Coal Authority data, Terrafirma’s expert knowledge of geohazards and advice from a panel of recognised industry professionals, to assess the risk to land and property in coal mining areas.

The report includes our expert opinion, which explains how coal mining could affect the property (and in turn the prospective purchaser and lender) and details any next steps that we recommend to safeguard their investment. This is backed up with our UserKey, which colour codes each section of the report for the appropriate party, and eliminates the requirement for the conveyancer to report on a liability they may not have detailed knowledge of and reduces the amount of time a conveyancer spends reporting back to the client and the lender.

Our professional expertise to provide straightforward answers as to whether coal mining could impact the property value, and whether any identified hazards need to be brought to the attention of the purchase or lender. Our clear ‘pass’ or ‘further action’ outcomes are clearly displayed on the front page, and the Terrafirma CON29M has a pass rate of over 99%.

Terrafirma were the first to include a Mine Entry Interpretive Report as standard in their official CON29M, where a mine entry (shaft or adit) is identified within 20 metres, saving approximately £150 in additional costs and ensuring that the discovery of a mine entry doesn’t slow down the transaction unnecessarily.
