Bristol Coalmining Archives Ltd

Please note that we are closed during the Covd-19 lockdown.

However, we are making alternative arrangements for the provision of emergency reports during this period. 

We are still able to continue to provide Enhanced Reports where they are part of a development. and Coal Mining Risk Assessments during this period, although there may be an unavoidable delay between enquiry, order and completion.

This is just a reminder of the reports which we provide:

  • Standard Reports are tailored to suit the requirements of the particular inquirer whether it be a solicitor acting on behalf of the purchaser of a single dwelling or an individual private client or a consultant investigating the planned development of a large site. They are normally accepted in lieu of a CON29M coalmining report.  
  • Enhanced Reports contain greater detail reflecting the more extensive historical research, including research into further background documents and literature, which is needed to complete these reports. Useful for developers planning building work and for consultants to use as part of their preliminary site investigations and/or as preparation for a Coal Mining Risk Assessment (see below).
  • Coal Mining Risk Assessments (CMRAs) These are required as part of a planning application for all new properties and extensions in areas which the Coal Authority (CA) consider to be within a Development High Risk area. These CMRAs are thoroughly researched, written and completed to comply the CA’s template.

We carry full professional indemnity; a copy of the certificate of this cover can be provided if requested.

We will keep you up-to-date with our changes as they occur.
