17. Retirement Benefit Obligations
The Company operates two defined benefit schemes and a defined contribution scheme.
(a) Uisce Éireann defined benefit pension schemes
The Company operates a contributory defined benefit scheme (“Uisce Éireann Defined Benefit Superannuation Fund”) as required under sections 19 and 27 of the Water Services (No. 2) Act 2013 in relation to employees of the Company, who were previously employed by either the Local Authorities or by the Department of Housing, Local Government and Heritage. This Scheme was established on 27 January 2017. The Company also operates a contributory defined benefit scheme (“Uisce Éireann (ex-Ervia) Superannuation Scheme”) in respect of employees who participated in the Ervia defined benefit pension scheme until legal separation from Ervia. On 1 January 2023, Uisce Éireann assumed the retirement benefit obligation in respect of the future service cost of relevant employees who transferred to Uisce Éireann from Ervia on legal separation. This scheme was established on 1 January 2023. Both schemes provide retirement benefits based on final pensionable salary and net pensionable salary in respect of future pensionable service, together with a “wrap around element” which maintains the final salary linkage in respect of prior pensionable service completed before joining Uisce Éireann.
The defined benefit schemes are administered by a Board of Trustees which comprises member and employer representatives. The respective Board of Trustees are responsible for the management and governance of the schemes including compliance with all relevant laws and regulations. The assets of the schemes are held separately from those of the Company in trustee administered funds. The latest valuation of the Uisce Éireann Defined Benefit Superannuation Fund was carried out as at 1 April 2025 by a qualified actuary. The next actuarial valuation is due with an effective date of 1 April 2028. The latest valuation of the Uisce Éireann (ex-Ervia) Superannuation Scheme was carried out as at 1 April 2023 by a qualified actuary. The next actuarial valuation is due with an effective date of 1 April 2026.
The schemes expose the Company to a number of risks, the most significant of which are as follows:
Asset volatility
The liabilities are calculated using a discount rate set with reference to corporate bond yields. If assets underperform this yield, this could create a larger deficit. The schemes hold a significant proportion of growth assets (equities) which, though expected to outperform corporate bonds in the long-term, create additional volatility and risk in the short-term.
Changes in bond yields
A decrease in corporate bond yields will increase the value placed on the liabilities for accounting purposes, although this will be partially offset by an increase in the value of any bond holdings held by the schemes.
Salary inflation
As a final salary scheme, there is an exposure to increased benefits arising as a result of higher salary increases than allowed for in the assumptions. The assumptions used to project final salary incorporate an age-related component in addition to a flat basic rate as an allowance for the effect of increments and promotions. The wraparound component of the benefit design (i.e. the linkage of pensionable service completed with a prior body) means that the accrued liabilities are particularly sensitive to higher than assumed salary growth.
Inflation
The schemes’ defined benefit obligations are linked to inflation (for active members, benefits are linked to salary increases while for deferred members, preserved benefits are linked on a discretionary basis to post retirement pension increases awarded or to statutory revaluation). Higher than assumed inflation will lead to higher liabilities. About a quarter of the fund is invested in inflation linked bonds as a match to such real liabilities.
Life expectancy risk
The majority of the schemes’ obligations are to provide benefits for the life of the member (and their dependants), so increases in life expectancy will result in an increase in the liabilities.

The weighted average duration of the Uisce Éireann (ex-Ervia) Superannuation Scheme defined benefit obligation at 31 December 2025 was approximately 23 years (2024: 26 years). The Company expects to contribute €2.5 million to its pension plan in 2026.
The principal actuarial assumptions used for the Uisce Éireann Defined Benefit Superannuation Fund (for 2024 and 2025) and Uisce Éireann (ex-Ervia) Superannuation Scheme (for 2024 and 2025) were as follows:
