26.Section 5 introduces a safeguard for beneficiaries in relation to powers of investment under section 3 or otherwise.  The new safeguard is that a trustee, when considering the exercise of a power of investment or carrying out a review of the investments of the trust, must obtain and consider proper advice about how, in view of the standard investment criteria (see note on section 4), the power to invest should be exercised or the investments of the trust be varied (section 5(1) and (2)).  However, as the imposition of an unqualified duty to take and consider advice before making any investment or change in investments would be unnecessarily burdensome, section 5(3) provides that the new duties to obtain advice will not apply if the trustee reasonably concludes that it is unnecessary or inappropriate to do so.  This would be the case, for example, if the proposed investment is small, so that the cost of obtaining advice would be disproportionate to the benefit to be gained from doing so, or where the trustees themselves possess skills and knowledge making separate advice unnecessary.  These provisions are at once more extensive and more flexible than the obligation to take advice in relation to most narrower and all wider range investments under the Trustee Investments Act 1961 section 6.  Where the 1961 Act does not apply at present, the obligation of a trustee to take advice (if any) is dependent upon the application of the rule that trustees must act with reasonable prudence in exercising powers of investment.
27.“Proper advice” is defined in section 5(4).  This definition is based on that in section 6(4) of the Trustee Investments Act 1961 and recognises that there may be circumstances in which a person is qualified to give advice by reason of his or her ability in and practical experience of issues other than financial matters.  Although financial expertise will be the primary attribute of an investment adviser, other skills may also be relevant.  For example, when an investment in land is proposed, the necessary qualities of the person giving the advice are likely to include expertise in the valuation of land.  In addition, if the trustees propose to invest in works of art, they would no doubt require advice from an expert in the relevant field.
28.Section 5(1) builds upon and extends the present duty on trustees wishing to invest in anything other than a very restricted class of investments (for example, National Savings Certificates and Bonds) to obtain and consider proper advice (such advice to be given or confirmed in writing) as to whether the investment is satisfactory bearing in mind the need for suitability and diversification (Trustee Investments Act 1961 section 6(2) and (5)).  There is no express requirement in section 5 for the advice to be given or confirmed in writing, but to do so will no doubt be regarded as best practice in many circumstances, and may be necessary for trustees to show compliance with the general duty of care in section 1.
29.The new general statutory duty of care is to apply in relation to the exercise of the duty to obtain and consider proper advice under section 5 (Schedule 1 paragraph 1(b)).
30.Subject to sections 36-38, which exclude the provisions of Part II from occupational pension schemes, authorised unit trusts or certain schemes under the Charities Act 1993 sections 6 and 7 define the trusts to which the new power of investment will apply.
