Coventry and Solihull Waste Disposal Company Ltd v. Russell

Factual and Procedural Background

Company A operates a waste-reduction unit in The City that was originally built by the local authority in the 1970s. The plant incinerates refuse, supplies heat via a pipeline to a neighbouring factory (Company B) and, after extensive alterations completed on 26 February 1993, also generates electricity—11.4 MW of which is exported to the grid operated by Company C.

On 1 April 1990 the Valuation Officer (Respondent) entered two separate assessments in the non-domestic rating list: one for the refuse destructor and premises (£610,000) and one for the pipeline (£38,500). Following the 1993 alterations the Respondent increased the refuse-destructor assessment to £1,150,000. Company A appealed, seeking (i) merger of the two assessments and (ii) valuation of the combined hereditament by the statutory “formula” set out in the Electricity Generators (Rateable Values) Order 1989 (“the 1989 Order”).

The local Valuation Tribunal rejected merger and formula valuation. On appeal, the Lands Tribunal ordered merger and applied the formula, reducing the rateable value to £143,034. The Respondent appealed. The Court of Appeal upheld merger but, by majority, ruled that the 1989 Order did not apply; the parties agreed the contractor’s method figure of £928,500 in consequence. Company A appealed to the House of Lords on that single issue.

Legal Issues Presented

1. Whether the combined hereditament, whose primary source of energy is the burning of refuse, qualifies for valuation under the 1989 Order pursuant to article 3(2)(a)(ii) (hereditaments whose “primary function is in connection with a scheme for the production for sale of both electrical power and heat”).
2. In resolving that question, how should the phrase “is in connection with” in article 3(2)(a)(ii) be construed?

Arguments of the Parties

Appellant’s Arguments

• Article 3(2)(a)(ii) requires only that there be a connection between the hereditament’s primary function (refuse incineration) and a combined heat-and-power (“CHP”) scheme; ordinary language suffices.
• The incineration process directly enables electricity and heat production, establishing the requisite link.
• Reading the provision broadly furthers the legislative purpose of encouraging environmentally beneficial undertakings that recycle energy from waste.

Respondent’s Arguments

• The paragraph demands that the primary function itself be the operation of a CHP scheme; the words “function is” focus on use, not mere association.
• Applying the formula where refuse destruction remains the primary function would omit a large part of the hereditament’s value, distorting rating equity.
• The 1991 amendment narrowed the provision intentionally; Company A’s reading would render that amendment ineffective.

Court’s Reasoning and Analysis

The House noted that article 3 requires three cumulative conditions: (1) use for generating electricity; (2) falling within one of the functional categories in 3(2)(a); and (3) meeting a capacity threshold in 3(2)(b). Company A satisfied the electricity-generation and capacity elements only if it could bring itself within article 3(2)(a)(ii).

Interpreting that paragraph, the Court emphasised:

• The 1991 amendment replaced “it is so used or available” with “its primary function is,” signalling an intention to restrict, not broaden, the provision’s scope. Focusing solely on “in connection with” would nullify the amendment.
• Syntactic symmetry: article 3(2)(a)(i) and (ii) are parallel; (i) demands that generation itself be the primary function, so (ii) naturally demands that use in a CHP scheme be the primary function.
• Valuation coherence: applying the formula where refuse disposal remains primary would exclude a substantial portion of the hereditament’s real worth, undermining uniformity among ratepayers.
• Policy logic: the appellant’s reading would let hereditaments with marginal CHP elements benefit, while excluding those whose principal activity is CHP but rely on refuse combustion and have under-25 MW capacity—an implausible legislative intent.

The explanatory note to the 1991 Amendment Order, though itself imperfect, supported this restrictive reading by stating that formula valuation applies “only if such use is the primary function of the hereditament.”

Holding and Implications

Appeal dismissed. The combined hereditament does not qualify for valuation under the 1989 Order because its primary function is refuse incineration, not operation of a CHP scheme. Consequently the contractor’s method valuation of £928,500 stands.

Implications: The decision clarifies that formula valuation under article 3(2)(a)(ii) is confined to hereditaments whose principal purpose is running a CHP scheme; ancillary or incidental connections are insufficient. The ruling reinforces rating consistency and offers guidance on construing ambiguous statutory language but does not establish a fundamentally new doctrine.
