The Electricity (Northern Ireland) Order 1992

25.  It is hereby declared for the avoidance of doubt that—

(a) the effect of Part III of this Order in relation to any contract of employment with Northern Ireland Electricity which is in force immediately before the transfer date is merely to modify the contract by substituting the appropriate successor company as the employer (and not to terminate the contract or vary it in any other way); and

(b) that Part is effective to vest the rights and liabilities of Northern Ireland Electricity under any agreement or arrangement for the payment of pensions, allowances or gratuities in the appropriate successor company along with all other rights and liabilities of Northern Ireland Electricity;

and accordingly any period of employment with Northern Ireland Electricity or a wholly owned subsidiary of Northern Ireland Electricity, shall count for all purposes as a period of employment with the appropriate successor company or (as the case may be), a wholly owned subsidiary of the appropriate successor company.
