Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel for STERIS plc, a public limited company incorporated under the laws of Ireland (“Parent”), STERIS Irish FinCo Unlimited Company, a public unlimited company incorporated under the laws of Ireland (the “STERIS Irish FinCo”), STERIS Corporation, an Ohio Corporation ( “STERIS Corp.”), and STERIS Limited, a private limited company organized under the laws of England and Wales (“STERIS Limited”), in connection with the authorization of the possible issuance and sale from time to time, on a delayed basis, of an indeterminate amount of: (i) ordinary shares, par value $0.001 per share, of Parent (the “Ordinary Shares”); (ii) preferred shares, par value $0.001 per share, of Parent (the “Preferred Shares”), in one or more series; (iii) senior debt securities of the Parent (the “Parent Debt Securities”), in one or more series; (iv) senior debt securities of STERIS Irish FinCo (the “FinCo Debt Securities,” and together with Parent Debt Securities, the “Debt Securities”), in one or more series; (v) warrants to purchase Ordinary Shares, Preferred Shares or Parent Debt Securities (the “Warrants”); and (v) units consisting of two or more of the Preferred Shares, Ordinary Shares, Parent Debt Securities (including any applicable Guarantees (as defined below)), FinCo Debt Securities (including any applicable Guarantees) or Warrants, or any combination of such securities (the “Units”), in each case, as contemplated by the Registration Statement on Form S-3 to which this opinion is an exhibit (the “Registration Statement”). STERIS Irish FinCo’s obligations under the FinCo Debt Securities may be guaranteed by Parent, STERIS Corp. and STERIS Limited (the “FinCo Debt Guarantees”). Parent’s obligations under the Parent Debt Securities may be guaranteed by STERIS Irish FinCo, STERIS Corp. and STERIS Limited (the “Parent Debt Guarantees”). In their capacities as guarantors, STERIS Irish FinCo, STERIS Corp. and STERIS Limited are collectively referred to herein as the “Subsidiary Guarantors,” and the Subsidiary Guarantors and Parent, it its capacity as guarantor of FinCo Debt Securities, are collectively referred to herein as the “Guarantors.” The FinCo Debt Guarantees and the Parent Debt Guarantees are collectively referred to herein as the “Guarantees.” The Ordinary Shares, the Preferred Shares, the Debt Securities, the Warrants, the Units and the Guarantees are collectively referred to herein as the “Securities.” The Securities are to be issued from time to time pursuant to Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”).

In connection with the opinions expressed herein, we have examined such documents, records and matters of law as we have deemed relevant or necessary for purposes of such opinions. Based on the foregoing, and subject to the further limitations, qualifications and assumptions set forth herein, we are of the opinion that:

The Debt Securities, when executed by STERIS Irish FinCo or Parent, as applicable, and authenticated by the trustee in accordance with the applicable Indenture (as defined below), issued and sold in accordance with the Registration Statement and delivered to the purchaser or purchasers thereof upon receipt by STERIS Irish FinCo or Parent, as applicable, of such lawful consideration therefor as the Board of Directors (or an authorized committee thereof) or other governing body of STERIS Irish FinCo or Parent, as applicable, may determine, will constitute valid and binding obligations of STERIS Irish FinCo or Parent, as applicable.

For purposes of our opinions insofar as they relate to the Guarantors, we have assumed that the obligations of each Guarantor under the Guarantees are, and would be deemed by a court of competent jurisdiction to be, in furtherance of its corporate or other entity purposes, or necessary or convenient to the conduct, promotion or attainment of the business of the respective Guarantor and will benefit the respective Guarantor, directly or indirectly.

As to facts material to the opinions and assumptions expressed herein, we have relied upon oral or written statements and representations of officers and other representatives of Parent, STERIS Irish FinCo, STERIS Corp., STERIS Limited and others. The opinions expressed herein are limited to the laws of the State of New York and the laws of the State of Ohio, in each case as currently in effect, and we express no opinion as to the effect of the laws of any other jurisdiction.
