1. Case Overview
+
Case: Sutton and East Surrey Water Plc v Monarch Chemicals Limited and Muztrans Ltd [2026] EWHC 1260 (TCC)
Court: High Court of Justice, Technology and Construction Court
Judge: Adrian Williamson KC, sitting as a Deputy Judge of the High Court
Hearing Date: 27 to 30 April and 4 May 2026
Judgment Date: 26 May 2026
Case No: HT-2023-000015 and HT-2023-000039

A delivery error at SES Water's Elmer treatment works caused a substantial loss claim. Monarch settled that claim for just over £5.6 million and pursued a contribution from Muztrans, employer of the delivery driver. The court decided whether Muztrans owed SES Water the same liability and, if so, whether the contractual and RHA Conditions excluded, limited or barred recovery (paragraphs 1-6 and 86).

Central Legal Test: Sections 1, 2 and 6 of the Civil Liability (Contribution) Act 1978 required Muztrans to be liable to SES Water for the same damage as Monarch. The court also construed the Monarch-Muztrans agreement and incorporated RHA Conditions, tested their reasonableness under the Unfair Contract Terms Act 1977, and considered contributory negligence and apportionment on the counterfactual basis (paragraphs 83-86).
Incident
+
The incident occurred on 2 February 2017 during a chemical delivery at the Elmer Water Treatment Works. Monarch supplied chemicals and Muztrans supplied haulage and employed the driver (paragraphs 1 and 7-11).
Settlement
+
Monarch paid SES Water just over £5.6 million shortly before trial. SES Water discontinued against Muztrans, leaving Monarch's contribution claim to be tried (paragraph 1).
Evidence
+
The evidence was sparse because SES Water's witnesses and the unwell driver did not give live evidence. The court placed primary weight on contemporaneous documents (paragraphs 3-6).
2. Procedural History
+
Agreed Questions
+
The parties agreed the contribution, contractual-bar and counterfactual apportionment questions for decision (paragraphs 2 and 86).
Counterfactual Findings
+
Although the primary claim failed, the court stated its conclusions on contractual limits, contributory negligence and apportionment in case that conclusion was wrong (paragraphs 83-86).
3. Defendant's Position
+

Muztrans denied owing SES Water a duty of care or joint vicarious liability, denied liability for the same damage, and relied on the contract and incorporated RHA Conditions as excluding, limiting or time-barring any contribution claim (paragraph 86).

No Relevant Liability
+
Muztrans said the driver's day-to-day work and pump-over procedure were directed by Monarch, so Muztrans did not share Monarch's liability to SES Water.
Contractual Protection
+
It relied on Conditions 6, 9, 11, 12 and 13 of the RHA Conditions 2009 and their incorporation into its contract with Monarch.
4. Claimant's Position
+

Monarch argued that Muztrans, as the driver's employer and haulage contractor, was jointly responsible for the delivery failure and should contribute to the reasonable settlement paid to SES Water.

Employment and Delivery
+
Monarch relied on Muztrans's formal employment of the driver and its contractual provision of drivers trained in pump-over deliveries (paragraphs 8-12).
Reasonable Settlement
+
The reasonableness of Monarch's settlement payment was common ground (paragraph 84).
5. Court's Analysis
+
No Duty to SES Water
+
Muztrans did not owe SES Water the alleged tortious duty of care (paragraph 86(1)(a)).
No Joint Vicarious Liability
+
Muztrans was not jointly vicariously liable with Monarch for the driver's negligence and was not liable for the same damage (paragraph 86(1)(b)-(c)).
RHA Conditions Effective
+
The RHA Conditions 2009 were fully incorporated, had the stated meaning and effect, and were reasonable under the Unfair Contract Terms Act 1977. Any contribution liability would have been excluded, limited or time-barred (paragraph 86(2)).
SES Water's Contributory Fault
+
On the counterfactual case, inadequate delivery procedures justified a 33% reduction for SES Water's contributory negligence, which would cap Muztrans's contribution liability under section 2(3) (paragraphs 82-86).
Counterfactual Shares
+
Had liability existed, responsibility for the remaining 67% would have been divided 85% to Monarch and 15% to Muztrans, producing overall shares of 57% and 10% respectively (paragraphs 85-86).
6. Decision and Outcome
+
Winner: The Second Defendant and Part 20 Defendant (Muztrans Ltd) succeeded.

Result: Monarch was not entitled to any contribution from Muztrans. Muztrans owed no relevant duty, was not jointly vicariously liable and was not liable for the same damage. Any liability would also have been excluded, limited or barred by the contract and RHA Conditions (paragraph 86). The First Defendant and Part 20 Claimant (Monarch Chemicals Limited) did not succeed on this application.

Practical Effect: Monarch bore its settlement without recovery from Muztrans. The court's alternative findings would in any event have confined Muztrans to a small share after SES Water's contributory negligence.
Contribution Refused
+
The statutory same-damage requirement was not met (paragraph 86(1)).
Contractual Defence Upheld
+
The incorporated RHA Conditions independently defeated or restricted the claim (paragraph 86(2)).
Alternative Allocation
+
The non-binding alternative allocation was SES Water 33%, Monarch 57% and Muztrans 10% (paragraphs 83-86).
7. Key Legal Principles and Practice Points
+
Same Damage
+
A contribution claim requires both parties to be liable to the injured party for the same damage; employment or commercial involvement alone is insufficient.
Contract Terms
+
Contribution exposure can be affected by validly incorporated exclusion, limitation and time-bar terms, subject to statutory controls.
Section 2(3) Cap
+
A defence available to the contribution defendant against the injured party, including contributory negligence, can cap the amount recoverable in contribution.
Apportionment
+
The just and equitable division examines practical direction, comparative fault and causative responsibility.
Practice Implications
+
For Claimants:
Before settling, identify the proposed contributor's direct legal liability to the injured party for the same damage and audit every incorporated exclusion, limitation and notice provision.
For Defendants:
Separate formal employment from operational control. Preserve the contract chain, incorporated trading conditions, training records and contemporaneous delivery procedures.
General Practice Points:
A reasonable settlement does not by itself create a contribution right. Liability for the same damage and any contractual defences remain threshold issues.
