Introduction to conservation reports

Conservation reports are an important aspect of conservation work. Reports are used by conservators to record their investigations of items for which conservation is sought and to inform treatment proposals. During the preparation of a report a conservator will assess the object and its needs, and put forward advice on the steps that can be taken to ensure its conservation and future well being.

The type of report required and the amount of information to be gathered will depend largely on the needs of the client. As the client, you need to be clear about the level of information you require in a report and, if appropriate, the purpose for which it is to be used.

For example, bodies such as the National Lottery Heritage Fund or The Church of England - Cathedral and Church Buildings Division may require a report as a precursor to agreeing funding. These reports tend to be detailed and specific guidelines are often published by the relevant body. The preparation of a report is time consuming and you should establish whether the conservator will make a charge for this process.

Report types

Preliminary report - As the name suggests, a preliminary report is carried out before any conservation work is started. It will describe and, as far as possible, identify damage and causes of deterioration; it will inform the treatment proposal(s) and will ultimately guide the estimate or quotation given for work to be carried out.

Interim report - An interim report may be required at one or more stages in a larger project and may act as a trigger for subsequent phases of work. The need for interim reports should be identified at the outset as part of the overall project plan.

Final report - A final report is provided on completion of conservation work. It will normally include a description of the item prior to conservation, a record of treatment carried out and will normally include a photographic record of the item before, during and after conservation.

Condition report - Condition reports will form part of preliminary/interim/final reports, or they may be commissioned as distinct pieces of work to describe the condition of an item at a particular point in time (but not making recommendations for treatment) e.g. recording the condition of an item prior to it going on loan.


As basic guidance, reports will commonly include the types of information listed below.

However, not all of these elements will be appropriate for every conservation project. Your initial discussions with the conservator will provide guidance on which aspects are relevant to the project with which you are involved. Some bodies, such as The Church of England - Cathedral and Church Buildings Division have produced individual guidelines on the information that it requires to accompany Faculty and grant applications (please see the Church conservation section).


After completion

When conservation work has been completed, you should ask for a treatment record or written confirmation that work was carried out as originally specified in the treatment proposal. This information, together with the initial condition report should be kept with the item that has undergone conservation. It is your responsibility as custodian to ensure that this is the case and that the information is passed on to subsequent owners or made available to inform future conservation work.
