Summary of Legal Opinion

Factual and Procedural Background

Company A succeeded Company C as the non-household water supplier to premises at [Number] Main Street. Company A issued proceedings to recover £28,014.37 for water supplied between 1 April 2020 and 31 March 2021 based on readings from two meters. Company B disputed readings from one meter on the basis that the meter was defective, though the meter, when tested, fell within the prescribed limits of error. The parties instructed a joint Expert. The Expert's tests recorded the meter as operating within prescribed limits but he reported that certain mechanical faults (e.g. wear, scale causing digit-rollover) could not be excluded without dismantling the meter and stated that "something is not right" with the suspect meter.

At first instance Judge Ginesi held that Regulation 8 permitted the court to consider evidence other than the statutory test to prove a meter was defective and found on the balance of probabilities that the meter was defective, dismissing Company A's claim. On appeal Judge Simpkiss (the judge) held that Regulation 8 provides a statutory regime: a meter reading proved in accordance with the Regulations is evidence of volume unless the meter is proved to register incorrectly (i.e. by the prescribed test), and that the deputy district judge had erred in relying on the Expert to find the meter defective. Company B appealed on three grounds (interpretation of Regulation 8; overturning of factual findings; substitution rather than remittal). The appellate panel (judges referenced below) delivered reasons and the appeal was dismissed.

Legal Issues Presented

1. Whether Regulation 8 of the Water (Meters) Regulations 1988 is to be interpreted as providing that a meter reading proved in accordance with the Regulations is evidence of volume supplied unless the meter is shown to register incorrectly by the prescribed test, thereby excluding other evidence of unreliability;
2. Whether the deputy district judge erred in finding, on the available evidence (including the Expert's report), that the meter was defective and that the readings could not be relied upon;
3. Whether the judge below wrongly substituted his own finding rather than remitting the case for further evidence.

Arguments of the Parties

Appellant's Arguments (Company B)

• Attorney Parratt submitted Regulation 8(1) permits a meter-reading to be evidence of volume but does not exclude other evidence being adduced to show a meter was defective or that a reading cannot be relied upon.
• Testing under Regulation 6 shows accuracy only at time of test; other evidence (including Expert opinion and consumption patterns) can and should be admitted to establish prior incorrect registration or intermittent faults.
• Regulation 8(4) contemplates reliance on evidence about earlier periods and does not preclude non-test evidence.

Respondent's Arguments (Company A)

• Attorney Kitchener submitted the Regulations form a comprehensive statutory code: certified meter readings are evidence of volume unless, when tested under the prescribed method, a meter is found to exceed the prescribed limits of error.
• Allowing other evidence to displace a tested meter reading would create uncertainty and undermine the regulatory scheme.

Court's Reasoning and Analysis

The court addressed two interlinked matters: (1) statutory interpretation of Regulation 8 of the Water (Meters) Regulations 1988, and (2) the sufficiency of the factual and expert evidence that the meter was defective.

Majority view (Judge Lewis and Judge Peter Jackson):

1. The Regulations form a comprehensive statutory scheme for measuring volume and fixing charges by reference to meter readings; provisions for installation, testing and prescribed limits are integral to that scheme (sections 5(2)-(3) of the 1988 Act; Regulations 6, 8 and 9).
2. Regulation 8(1) provides that a reading proved in accordance with the Regulation is evidence of volume "unless the meter is proved to register incorrectly". Regulation 8(3) defines "registering incorrectly" by reference to the prescribed testing regime (i.e. a meter is regarded as registering incorrectly if, on being tested, it exceeds prescribed limits of error).
3. Read naturally and in context, the Regulations contemplate that a certified meter reading from a meter shown by the statutory test to be within prescribed limits is the basis for determining charges; the Rules for testing (Regulation 6) are the means of determining incorrect registration.
4. Allowing other forms of evidence to displace tested meter readings would undermine regulatory certainty, risk unmanageable challenges and be inconsistent with the statutory purpose of correlating charges with volume.
5. On the facts, the tested meter was within prescribed limits and recorded in "Good" condition; the Expert did not dismantle the meter and relied on possibilities and third-party statements. The evidence was therefore insufficient for the deputy district judge to find, on the balance of probabilities, that the meter had been registering incorrectly.

Dissenting / concurring view (Judge Snowden):

1. Judge Snowden observed the text of Regulation 8 does not expressly state a meter reading is the only admissible evidence and that Regulation 8(1) omits "conclusive" language; therefore, other evidence might be admissible in exceptional cases (e.g. intermittent or transient faults) to prove that a meter registered incorrectly in an earlier period even if it passed a later test.
2. He accepted that customers face an uphill task to prove such intermittent faults and that permitting other evidence would be exceptional; applying that approach, he found the Expert's material in this case insufficient because the Expert did not open/dismantle the meter and relied on untested lay statements.
3. Accordingly, although inclined not to read Regulation 8 as excluding all other evidence, he agreed the evidence here did not establish defective registration and would dismiss the appeal on that basis.

Holding and Implications

APPEAL DISMISSED

Holding: The appellate court dismissed Company B's appeal. The majority construed Regulation 8 as providing that a meter reading proved in accordance with the Regulations is evidence of the volume supplied and that a meter is only to be regarded as registering incorrectly if, on being tested under the prescribed regime, it is found to exceed the prescribed limits of error. Readings from meters shown by the prescribed test to be within limits are therefore the proper basis for charges.

Implications: The direct effect is that charges based on readings from a meter tested and found within prescribed limits are enforceable; a customer challenging such readings faces a substantial evidential burden. One judge indicated an alternative construction permitting exceptional reliance on other evidence of intermittent or transient faults, but in this case he agreed the factual evidence was insufficient. The decision clarifies the regulatory scheme's emphasis on statutory testing as the principal means of proving incorrect registration; it does not establish a novel rule permitting routine displacement of tested readings by other evidence.
