(b)the second test is met in relation to an assessment date if C, as calculated in accordance with paragraph 2 of this Schedule, is 0.10 or more.

(3) B is 0 unless the circumstances set out in sub-paragraph (4) apply.

(4) B is 0.05 if, in relation to the assessment date—

(b)the second test is met in relation to an assessment date if, as at that assessment date, the increase in expenditure forecast applicable to that tariff category is at least 50% of, but less than 150% of, the figure specified for that assessment date in the corresponding entry in the third column of the relevant table (“the anticipated increase figure”);

(c)the third test is met in relation to an assessment date if, as at that assessment date, the increase in expenditure forecast applicable to that tariff category is at least 150% of the anticipated increase figure;

(d)in relation to an assessment date other than the assessment date which falls on 30th April 2018, the fourth test is met if during the tariff period that immediately preceded the tariff period in which the assessment date falls, the value of C applicable to that tariff category was 0.10 or more,

Impact Assessments generally accompany all UK Government interventions of a regulatory nature that affect the private sector, civil society organisations and public services. They apply regardless of whether the regulation originates from a domestic or international source and can accompany primary (Acts etc) and secondary legislation (SIs). An Impact Assessment allows those with an interest in the policy area to understand:

  • Why the government is proposing to intervene;
  • The main options the government is considering, and which one is preferred;
  • How and to what extent new policies may impact on them; and,
  • The estimated costs and benefits of proposed measures.
