IAH Annual Report 2025
Finance
IAH has income and expenditure in sterling, euro and dollars. Owing to the Association being based in the UK it is required to prepare its formal reports and accounts in sterling. We have summarised our financial information here in all three currencies, for better understanding.
Income was significantly ahead of the budget forecast at the beginning of the year. This was partly because of increased membership and associated revenues, but to a large extent it was because of welcome donations following the successful congresses in Davos and Melbourne. There was also a currency exchange gain on paper of £7K. Royalties from our journal publisher were reduced because of tax paid at source in Germany. Arrangements for renewing our tax-exempt status in Germany are being managed by Springer and in due course a reimbursement will be made. Overall running costs increased in line with inflation.
The reserves carried forward at the end of 2025 amounted to £310K, including the restricted funds for the Burdon Fund. This puts IAH in a strong financial position for supporting its aims for members and charitable functions, particularly in respect of education and development.
IAH has its main bank account with Virgin Money. We are aware that a takeover of Virgin Money by Nationwide is in prospect. We will continue to monitor whether there may be implications for IAH resulting from this change.
IAH’s trading subsidiary, World-Wide Groundwater Ltd, remained dormant, but continued to hold £9K on behalf of the Association, which had been deposited following closure by HSBC of IAH’s bank account in 2022.
