The Welsh Archaeological Trusts produced an Access and Charging Policy, which sets out what types of information are available from the HER, what may be withheld, and the reasons for withholding information. Enquiry forms, to cover the provision of HER information, are currently downloadable from the Gwynedd Archaeological Trust website ( or are available upon request. The Welsh Archaeological Trusts' Access and Charging Policy can also be downloaded.

The form should be completed for each separate enquiry, although return visits relating to the same enquiry would not require multiple forms.

Anyone is welcome to visit the HER in person, but we request that an appointment is made in advance to ensure HER staff are available to aid the enquirer. Servicing enquiries is only one part of the role of HER staff, so this is essential.

HER enquiries will be dealt with free-of-charge to private individuals and academic researchers.

Archwilio may not be used for any commercial or development-related enquiries. These will still need to be dealt with by the HER staff and are likely to incur a charge, on a cost-recovery basis. Please contact the HER directly for further details.

The HER is open to the public on Monday to Friday, by appointment only, from 10 am to 4:30 pm. It is usually closed for lunch between the hours of 1 pm and 2 pm.
