Dear Sirs:


RE:      REGISTRATION STATEMENT ON FORM S-1
- ---      ----------------------------------


We are Cayman Islands Counsel to Yorkshire Power Finance Limited ("Yorkshire
Finance") in connection with the preparation of a registration statement on Form
S-1, including a preliminary prospectus, filed with the United States Securities
and Exchange Commission (the "Commission") on 13th March, 1998 (the
"Registration Statement"), contemplating the registration under the United
States Securities Act of 1933, as amended (the "Securities Act"), of Junior
Subordinated Deferrable Interest Debentures (the "Junior Subordinated
Debentures") to be issued by Yorkshire Finance and guaranteed by Yorkshire Power
Group Limited ("Yorkshire"). The Junior Subordinated Debentures will be issued
pursuant to a subordinated indenture, as supplemented, to be entered into
between Yorkshire Finance, Yorkshire and the trustee named therein (the
"Subordinated Indenture") in substantially the form filed as an exhibit to the
Registration Statement.

For the purposes of this opinion, we have reviewed the Companies Law (1995
Revision) of the Cayman Islands (the "Companies Law") and have examined and
relied upon:

1. the prospectus relating to the Junior Subordinated Debentures in the form
   included in the Registration Statement;
 
2. the Memorandum and Articles of Association of Yorkshire Finance;
 
3. Certificate of Incorporation of Yorkshire Finance;
 
4. the form of the Subordinated Indenture;
 
5. the Minutes of a Meeting of the Board of Directors of Yorkshire Finance held
   on 11th February, 1998 (the "Minutes"), the Power of Attorney granted by the
   Company on 11th February, 1998 and the corporate records of Yorkshire
   Finance; and

6.  a Certificate from a Director of Yorkshire Finance in the form annexed
    hereto (the "Director's Certificate").



The following opinion is given only as to circumstances existing on the date
hereof and known to us and as to the laws of the Cayman Islands as the same are
in force at the date hereof.  In giving this opinion, we have relied upon the
accuracy of the Director's Certificate without further verification and have
relied upon the following assumptions, which we have not independently
verified:-


(a)  The Junior Subordinated Debentures and the Subordinated Indenture will be
     duly authorised, executed and delivered by or on behalf of all relevant
     parties (other than Yorkshire Finance) and will be legal, valid, binding
     and enforceable against all relevant parties in accordance with their
     respective terms under the laws of the State of New York and all other
     relevant laws (other than the laws of the Cayman Islands);

(b)  The choice of the laws of the State of New York as the governing law of the
     Junior Subordinated Debentures and the Subordinated Indenture will be made
     in good faith and would be regarded as a valid and binding selection which
     will be upheld by the courts of the State of New York as a matter of New
     York  law and all other relevant courts (other than the courts of the
     Cayman Islands);

(c)  Copy documents or the forms of documents provided to us are true copies of,
     or in the final forms of, the originals;

(d)  The genuineness of all signatures;

(e)  The power, authority and legal right of all parties under all relevant laws
     and regulations (other than Yorkshire Finance under the laws of the Cayman
     Islands) to execute and perform their respective obligations under the
     Junior Subordinated Debentures and the Subordinated Indenture;

(f)  The Junior Subordinated Debentures will be duly completed, executed and
     authenticated and delivered in accordance with, and as contemplated by, the
     provisions of the Subordinated Indenture;

(g)  That all preconditions to the obligations of the parties to the Junior
     Subordinated Debentures and the Subordinated Indenture have been or will be
     satisfied or duly waived and there has been no breach of the terms of the
     Junior Subordinated Debentures or the Subordinated Indenture; and

 
                                       3

(h)  There is nothing under any law (other than the laws of the Cayman Islands)
     which would or might affect the opinions hereinafter appearing.
     Specifically, we have made no independent investigation of the laws of the
     State of New York.


We render no opinion as to the negotiability or transferability by delivery of
any Junior Subordinated Debentures in any jurisdiction which does not recognise
such negotiability or transferability.

Based upon and subject to the foregoing and having regard to such legal
considerations as we deem relevant, we are of the opinion that:-

1.  Yorkshire Finance has been duly incorporated and is validly existing under
    the laws of the Cayman Islands;
 
2.  Assuming that the precise terms of issue of the Junior Subordinated
    Debentures are duly determined by an Attorney of the Company in accordance
    with the resolutions set forth in the Minutes, the Subordinated Debentures
    have been duly authorised by Yorkshire Finance and, when executed on behalf
    of Yorkshire Finance, authenticated in the manner set forth in the Junior
    Subordinated Indenture and delivered against due payment therefor, will
    constitute the legal, valid and binding obligations of Yorkshire Finance
    enforceable in accordance with their terms, except and insofar as such
    enforcement may be limited as hereinafter set forth. The term "enforceable"
    as used above means the obligations assumed by Yorkshire Finance under the
    Junior Subordinated Debentures are of a type which the Courts of the Cayman
    Islands enforce. It does not mean those obligations will necessarily be
    enforced in all circumstances in accordance with their terms and we would
    draw to your attention:

(i)     enforcement may be limited by bankruptcy, insolvency, liquidation,
        reorganization and other laws of general application relating to or
        affecting the rights of creditors;

(ii)    enforcement may be limited by general principles of equity - for
        example, equitable remedies such as specific performance may not be
        available, inter alia, where damages are considered to be an adequate
        remedy;

(iii)   claims may become barred under the statutes of limitation or may be or
        become subject to defences of set-off or counterclaim;

(iv)    where obligations are to be performed in a jurisdiction outside the
        Cayman Islands, they may not be enforceable in the Cayman Islands to the
        extent that performance would be illegal under the laws of that
        jurisdiction;

(v)     in the event of any proceedings being brought in the Cayman Islands
        courts in respect of a monetary obligation expressed to be payable in a
        currency other than Cayman

        Islands dollars, a Cayman Islands court will give judgement expressed as
        an order to pay such other currency on enforcement of the judgement.
        With respect to winding up proceedings, Cayman Islands law will require
        that all claims or debts are converted into Yorkshire Finance's
        functional currency of account;

(vi)    Cayman Islands stamp duty will be payable if any of the Junior
        Subordinated Debentures or the Subordinated Indenture is brought to or
        executed in the Cayman Islands, which duty would be up to CI$250 on each
        of the Junior Subordinated Debentures (unless Yorkshire Finance has paid
        a duty of CI$500 in respect of the issue of the Junior Subordinated
        Debentures) and would be CI$40 on the Subordinated Indenture;

(vii)   a certificate, determination, calculation or designation of any party to
        the foregoing documents as to any matter provided therein might be held
        by a Cayman Islands court not to be conclusive, final and binding if,
        for example, it could be shown to have an unreasonable or arbitrary
        basis or in the event of manifest error;

(viii)  although there is no statutory enforcement in the Cayman Islands of
        judgments obtained in New York, the courts of the Cayman Islands will
        recognise and enforce a foreign judgment of a court of competent
        jurisdiction without reexamination or relitigation of the matter
        adjudicated upon, based on the principle that a judgment of a competent
        foreign court imposes upon the judgment debtor an obligation to pay the
        sum for which judgment has been given, and provided such judgment is
        final, for a liquidated sum not in respect of taxes or a fine or
        penalty, and which was not obtained in a manner, and is not of a kind
        the enforcement of which is, contrary to the public policy of the Cayman
        Islands; a Cayman Islands court may stay proceedings if concurrent
        proceedings are being brought elsewhere;

(ix)    obligations to make payments that may be regarded as penalties will not
        be enforceable to the extent that they are penal;

(x)     in principle a Cayman Islands court will award costs and disbursements
        in litigation in accordance with contractual provisions in this regard
        but the applicable rule of court (GCR Order 62, rule 2) has been in
        force only since 1st June, 1995 and there remains some uncertainty as to
        the way in which it will be applicable in practice. Whilst it is clear
        that costs incurred prior to judgement can be recovered in accordance
        with the contract, it is likely that post-judgment costs will be
        recoverable, if at all, in accordance with the scales laid down in the
        Grand Court (Taxation of Costs) Rules 1995;

(xi)    we reserve our opinion as to the extent to which a Cayman Islands court
        would, in the event of any relevant illegality, sever the offending
        provisions and enforce the remainder of the transaction of which such
        provisions form a part, notwithstanding any express provisions in this
        regard;

(xii)  to maintain Yorkshire Finance in good standing under the laws of the
       Cayman Islands, annual filing fees must be paid and Returns made to the
       Registrar of Companies;

(xiii) the obligations of Yorkshire Finance under the Junior Subordinated
       Debentures or the Subordinated Indenture which involve the government of
       any country which is currently the subject of United Nations sanctions as
       extended to the Cayman Islands by an Order in Council (namely Iraq and
       Libya and each an "Affected Country"), any person or body resident in,
       incorporated in or constituted under the laws of any Affected Country or
       exercising public functions in any Affected Country or any person or body
       controlled by any of the foregoing or by any person acting on behalf of
       any of the foregoing may be subject to restrictions pursuant to such
       sanctions as implemented under the laws of the Cayman Islands;

(xiv)  if Yorkshire Finance obtains a beneficial interest in any of the Junior
       Subordinated Debentures then its rights and obligations in respect
       thereof may merge thus extinguishing its rights and obligations in
       respect thereof, so that any attempted resale of those Junior
       Subordinated Debentures might constitute a separate issue of debt
       obligations;

(xvi)  we make no comment with regard to the references to foreign statutes in
       the Junior Subordinated Debentures or the Subordinated Indenture.

This opinion is solely for the benefit of the addressee but may be relied upon
by the addressee's legal advisors (in that capacity only).  It may not be relied
upon by (nor may it be disclosed to) any other person, without the prior written
consent of this firm.  However, we do hereby consent to the filing of this
opinion as an exhibit to the Registration Statement and to the reference to us
under the heading "Legal Opinions" in the prospectus included in the
Registration Statement.  In giving such consent, we do not thereby admit that we
are in the category of persons whose consent is required under Section 7 of the
Securities Act or the rules or regulations of the Commission thereunder.

Yours faithfully
