# The Community Charges (Administration and Enforcement) Regulations 1989, Paragraph 7


(1) This paragraph applies where the demand notice has been served on a chargeable person by a charging authority, the event mentioned in paragraph 6(1) has not occurred in relation to the notice, and
(a) the notice was so served on the understanding or assumption that on any day in the period to which the notice relates the person is not or will not be undertaking a full-time course of education, and after the issue of the notice the community charges register shows that person as undertaking such a course on that day;
(b) the notice was so served on the understanding or assumption that on any day in the period to which the notice relates the person is or will be undertaking a full-time course of education, and after the issue of the notice the community charges register shows that person as not undertaking such a course on that day;
(c) the notice was so served by reference to an amount set by the charging authority for its personal community charge for the relevant year and after the issue of the notice the authority sets a different amount for the charge in substitution for that amount under section 34 or 35 of the Act;
(d) the notice was so served in relation to a standard community charge, and the property by virtue of which the person is shown as subject or becoming subject to the charge is shown in the register as falling on any day in the period to which the notice relates into a class specified under regulation 62 for which the standard community charge multiplier is greater or less than that by reference to which the notice was issued;
(e) the notice was so served on the understanding or assumption that, on any day in the period to which the notice relates, the person is or will be entitled to a reduction in the amount he is liable to pay in respect of the community charge concerned under regulations made under section 31A(1) of the Social Security Act 1986, and he is allowed a larger or smaller reduction than had been so assumed;
(f) the notice was so served on the understanding or assumption that, on any day in the period to which the notice relates, the person is not or will not be entitled to a reduction in the amount he is liable to pay in respect of the community charge concerned under regulations made under section 31A(1) of that Act, and he is allowed such a reduction; or
(g) by virtue of regulations made under section 31D(1) to (3) of that Act a liability falls to be met by the person in respect of the community charge concerned in the manner mentioned in subsection (3)(b) of that section for which provision was not made in making the calculation under regulation 16(3) with respect to the notice.
(2) The charging authority shall on or as soon as practicable after the relevant day–
(a) serve a notice on the chargeable person which is to state the amount of the revised estimate mentioned in sub-paragraph (3), and
(b) adjust the instalments (if any) payable on or after the adjustment day (“the remaining instalments”) so that they accord with the amounts mentioned in sub-paragraph (4).
(3) The revised estimate is the revised estimate of the charging authority of the amount that the person is liable to pay in respect of the charge as it has effect for the relevant year, made on the assumptions mentioned in regulation 16(3) and as if the notice mentioned in that provision were the notice referred to in sub-paragraph (2) above.
(4) The aggregate amount of the remaining instalments payable shall be equal to the amount by which the revised estimate mentioned in sub-paragraph (3) exceeds the aggregate amount of the instalments payable under the demand notice before the adjustment day; and the amount of each remaining instalment (if there are more than one) shall be calculated in accordance with paragraph 1(4) and (5) as if references in those provisions to the aggregate amount and to instalments were references to the aggregate amount of the remaining instalments and to the remaining instalments respectively.
(5) If the revised estimate mentioned in sub-paragraph (3) exceeds the aggregate amount of the instalments payable under the demand notice before the adjustment day, but no instalments are payable under it on or after that day, the amount of the excess shall be due from the chargeable person to the charging authority in a single instalment on the expiry of such period (being not less than 14 days) after the day of issue of the notice served under sub-paragraph (2) as is specified in it; and if in any case the revised estimate is less than the aggregate amount of the instalments payable before the adjustment day, any overpayment–
(a) shall be repaid if the chargeable person so requires, or
(b) in any other case shall (as the charging authority determines) either be repaid or credited against any subsequent liability of the person to make a payment in respect of any community charge of the authority.
(6) Where a notice has been given under sub-paragraph (2), in the operation of this paragraph as respects any further notice that may fall to be given under it, references in this paragraph to the demand notice and to amounts in respect of instalments payable under it shall be construed (so far as the context permits) as references to the demand notice, and amounts in respect of instalments payable under the notice, as from time to time previously adjusted under this paragraph; and in calculating the aggregate amount of instalments payable under a demand notice before the adjustment day for the purposes of sub-paragraphs (4) and (5) in consequence of the making of a revised estimate under sub-paragraph (3), there shall not count as so payable any amount in respect of such instalments which has fallen to be repaid (or credited) under section 36(2) of the Act or (on the occasion of the making of a previous revised estimate under sub-paragraph (3)) under sub-paragraph (5) above.
(7) In this paragraph–
“the adjustment day” means the day 14 days after the day the notice served under sub-paragraph (2) is issued; and
“the relevant day” means the day with respect to which the understanding or assumption mentioned in sub-paragraph (1)(a), (b), (e) or (f) is wrong, the day the amount set in substitution mentioned in sub-paragraph (1)(c) is so set, the day the property falls into the class mentioned in sub-paragraph (1)(d), or the day on which the liability to be met in the manner mentioned in sub-paragraph (1)(g) first so falls to be met (as the case may be).
