     (2)  Where during a relevant year -

                (i)  premises A are occupied by more than one person;

                (ii) customer B supplies the other person or persons who are in

                of the Act from the requirement to hold a licence to supply; and

                (iv) customer B does not supply an aggregate quantity of
                electricity to such other occupiers in any relevant year which

                permitted quantity,

          the occupation of premises A by the persons other than customer B
          shall be deemed to be occupation by customer B.

          standard tariff price per unit charged by that public electricity
          supplier for customers of the type or types of such other occupiers

                occupier of premises A who has a relevant demand above the
                franchise limit;

                (ii) the quantity of electricity supplied to customer B equal to
                the quantity supplied by customer B in accordance with
                subparagraph (i); and

                (iii) the occupation by the occupier (other than customer B)
                referred to in subparagraph (i).

     (6)  To the extent that, disregarding subparagraph (2), the licencee would
          have been permitted to provide a supply to customer B's premises under
          this Condition, the provisions of this paragraph shall not apply.

CONDITION 3. CONTROLLED MARKET START-UP
- ---------------------------------------

1. This Condition applies to those premises which the Licensee would during the
   franchise period be prohibited from supplying under the terms of Condition 2.

2. The Licensee shall not, after the expiry of the franchise period, supply
   electricity to any premises to which this Condition applies prior to such
   date as is specified in respect of such premises in a direction issued by the
   Director under this Condition.

3. A direction under this Condition may specify that different premises may be
   supplied from different dates, and for the purposes of this Condition
   premises may be specified by reference to:

   (a) their location;

   (b) whether or not they are Domestic Premises; or

   (c) the type of metering equipment installed at the premises,
       or any combination of these factors.

4.  Prior to making any direction under this Condition, the Director shall:

   (a) set out the proposed contents of the direction in a notice (the
       "proposals notice");

   (b) send the proposals notice to the Licensee, each Relevant Public
       Electricity Supplier in respect of premises specified in the notice, each
       consumers' committee appointed for an area within which the premises
       specified in the notice are situated and any other persons or bodies
       appearing to the Director to be representative of those likely to have an
       interest; and

   (c) consider any representations concerning the proposed contents of the
       direction which are made within a reasonable period, being not less than
       7 days from the date of issue of the proposals notice.

5.  Any direction issued by the Director under this Condition shall be in
    writing and shall be made not less than 28 days prior to the first date
    specified in the direction.

6.  Where, by virtue of this Condition, thc Licensee is prohibited from
    supplying any premises, the provisions of Condition 29 shall not apply in
    relation to the supply of electricity to those premises.

7.  When the Director has issued a direction under this Condition and it appears
    to him, having regard to the considerations set out in paragraph 8, that it
    would be unreasonable in all the circumstances for the direction to have
    effect on the dates specified therein in respect of any or all of those
    premises at which it has not yet had effect, then the Director may, subject
    to paragraph 9, withdraw or vary the direction

 
   in respect of the premises to be supplied or of the dates from which they may
   be supplied, or both.

8. The considerations set out in this paragraph are:

   (a) whether the interests of customers in general, and in particular the
       interests of those occupying the premises specified in the direction,
       would be served by the withdrawal or variation of the direction;

   (b) whether the interests of any Electricity Supplier, including the
       Licensee, would be or would be likely to be unfairly prejudiced by the
       withdrawal or variation of the direction, or by a failure to do so;

   (c) the content of any representation made to the Director on the issue; and

   (d) such information as is available to the Director concerning:

        (i)   the manner in which arrangements for the supply of electricity to
              any premises to which this Condition applies have operated and are
              expected to operate;

        (ii)  the likely ability of the Licensee to fulfil its obligations under
              its Licence with respect to the supply of electricity to any of
              the premises concerned; and

        (iii) the likely ability of each Relevant Public Electricity Supplier to
              comply with the requirements of its public electricity supply
              licence in respect of the supply of electricity by the Licensee to
              the premises concerned.

9.  The Director shall not withdraw or vary a direction in respect of any
    premises when the date specified from which supply may commence is less than
    14 days from the date of the withdrawal or variation, unless the Director
    has the agreement of the Licensee, or failing that agreement the agreement
    of no fewer than two-thirds of the Second Tier Suppliers to whom a direction
    applies in respect of the same premises and dates.

10. When the Director withdraws or varies a direction in accordance with
    paragraph 7, he shall issue a notice of withdrawal or variation (as the case
    may be) and that notice shall have effect.

11. The Director shall publish any direction, or any notice of withdrawal or
    variation in such manner as in the opinion of the Director will secure
    adequate publicity for it.

12. A direction or a variation or withdrawal of a direction made under this
    Condition shall not distinguish between the Licensee and other Second Tier
    Suppliers except to the extent that the distinction is appropriate in all
    the circumstances given:

    (a) the information available to the Director in accordance with sub-
    paragraph 8(d)(ii); or

 
  (b) where the Licensee is also a public electricity supplier, any failure by
      the Licensee to comply with the requirements of its public electricity
      supply licence, or with any agreement entered into in accordance with any
      such requirements, which adversely affects the ability of private
      electricity suppliers to supply electricity to any customers within its
      authorised area.

CONDITION 32. PROVISION OF SERVICES FOR PERSONS WHO ARE OF PENSIONABLE AGE OR
- -----------------------------------------------------------------------------
DISABLED OR CHRONICALLY SICK
- ----------------------------

1. The Licensee shall within two months of serving a Designated Supply Notice on
   the Director prepare and submit to the Director for his approval a code of
   practice detailing the special services the Licensee will make available for

      pensionable age or disabled or chronically sick, to require:

 
     (i)  information and advice in respect of the matters set out at paragraph
          2; or

     (ii) advance notice of interruptions to the supply of electricity;

   (b) maintain such a register, comprising the relevant details of each

           set out in the code of practice; and

      (ii) notice of the existence of another register maintained by the
           Relevant Public Electricity Supplier, in relation to such customers
           who may be expected to require advance notice of interruptions to the
           supply of electricity, on which such customers may be included.

4. The Licensee shall, with the consent or at the request of any customer
   included on the register maintained in accordance with sub-paragraph 3(b),
   provide the Relevant Public Electricity Supplier with appropriate details
   concerning such customer and his requirements for the purpose of his
   inclusion on the equivalent register maintained by the Relevant Public
   Electricity Supplier in accordance with the provisions of its public
   electricity supply licence.
