All other Classes we expect daily reads.
6 month average 50.13% This rejection occurs when a meter read is being submitted too often for the Meter Read Frequency (MFR). Please be aware, this will also apply to a cyclic read received following the submission of a shipper transfer read. MRE00490 Frequency of Submission Rule The read will not be accepted if the period from the last read date to the submitted read date is:Monthly Read Meter Less than 7 Calendar Days Annual Read Meter (Large Supply Meter Point) AQ > 73,200 Less than 14 Calendar Days Annual Read Meter (Small Supply Meter Point) AQ < 73,200 Less than 25 Calendar Days
MRE00490 - A breach of the allowed reading submission frequency occurred A meter read frequency of monthly should be applied where the AQ is above 293000, or where a smart meter or a AMR is attached/installed. The site should either have its MRF or class adjusted to allow more reads to be submitted, or the shipper should be reducing the amount of reads being submitted in line with MRF of the site. If you have a smart meter attached or AMR equipment and would prefer to submit daily readings, you can change to a Class 3, and submit your reads in batches. Please note, in order to meet your performance obligations you must submit daily reads for a Class 3. MRE01029 Reading breached the upper Inner tolerance value and no override flag provided This rejection code is because a read has been submitted which is too high for the inner tolerance and has not been flagged. Upper AQ Band Lower AQ Band Read Accepted without Tolerance flag The flag is your confirmation that whilst the consumption is high, you accept that the read is correct.

An option that could be put forward by a Shipper is to change the tolerance values, however you would need to submit a MOD for this and it would need to be agreed industry wide.
MRE01029 Calculating Volume and Energy from reads Volume = Read 2 Read 1 x Correction Factor x Read Factor x Conversion Factor conversion factor is equal to 2.83 for imperial to metric conversion ( )= 3 ( ) 3.6 Energy Calculation Example AQ = 4600 Previous Actual read for 24/8/17 of 2728. Current read received for 1/3/18 of 4452. Metric meter with Correction Factor of 1.02264 and using an average CV of 39. Consumption = 1763 and Energy = 19100 MRE01029 Calculating Tolerance Energy Tolerance energy = AQ / 365 x number of days between reads x tolerance threshold (%) Tolerance Calculation Example Energy 19100 from previous slide Tolerance levels are:Accepted without flag up to (4600/365 * 188 days)* 400% = 9477 Requires a flag up to (4600/365 * 188 days)* 7000% = 165852 Reject as a Market Breaker above (4600/365 * 188 days)* 7000% = 165852 This read would have required a Tolerance Override Flag of Y
Lower AQ Band 1001 Upper AQ Band Read Accepted without Tolerance flag 5000 0% - 400% of AQ Read Accepted with Tolerance flag > 400% - 7000% of AQ Read Rejected > 7000% of AQ MRE01027 Reading Breached the upper Outer Tolerance This rejection code is because the read is completely over the upper tolerance (market breaker) This could be because of an AQ issue. If so, we would advise to complete an AQ correction. This could be because the read is wrong. Upper AQ Band Lower AQ Band Read Accepted without Tolerance flag Read Accepted with Tolerance flag

6 month average 1.08% *Snapshot of tolerance table MRE01016 Actual Read can only be replaced by a replacement read A read has been submitted and accepted with read reason N (nonopening) Another read has been submitted with read reason N, with the same date A read has been submitted and accepted with read reason N (nonopening) Another read has been submitted with read reason R (replacement)* with the same date Rejection! Accept If you need to change a read, you must submit with a read reason of R for replacement. *We have a change due in June 19 (4670) which will reject any replacement reads with the same date, the same read and the same TTZ count. 6 month average 10.02% MRE00457 New Meter Reading is less than previous meter reading
MRE01026 Reading breached the lower outer tolerance Both of these rejection codes mean the read that has been submitted is lower than the previous read denoting that there is negative consumption. Potentially a round the clock count needs to be provided, along with the read. Potentially a read has been submitted, however the Shipper has not submitted an RGMA flow for a meter exchange, for a date prior to the submitted read date. Potentially previous read was derived following an RGMA being submitted without reads. These derived reads are treated as actual reads. *If a convertor is present only MRE00457 will be received where the meter reading is less than the previous meter reading, however the convertor reads are aligned. MRE00457 6 month average 4.82% MRE01026 6 month average 4.71% MRE00419 The meter serial number on the read does not agree with the meter serial number held on the Transporter Database This means the serial number provided on the read does not match the serial number on UK Link. A potential reason for rejection is that a physical meter exchange has taken place but an RGMA update has not been submitted or has been rejected. 6 month average 2.71% MRE00489 Non-opening reading received outside the read receipt window Class 3 Class 4
Received a read over M +10 (calendar days) from the read date. Received a read over 25 business days from the read date. 6 month average 1.40% CNF00011 Confirmation not owned by requesting system user Only the Shipper with ownership of the site at the date the reading was taken is allowed to submit the read. 6 month average 0.01% We suggest checking on Data Enquiry Service (DES) of the status of ownership. Please note, DES is D + 1 or contacting our telephone service to confirm ownership.
