Investing.com -- Severn Trent (LON:SVT) on Thursday reported a 65% drop in average storm overflow spills during the first half of 2025, highlighting a strong start to the new five-year regulatory cycle, AMP8.

The company said it completed over 2,000 storm overflow interventions, bringing the average number of spills to five in the six months to June, down from an average of 14.3 during the same period last year.

The reduction keeps Severn Trent on track to meet its full-year target of reducing average spills to fewer than 10.

Severn Trent also confirmed it expects to deliver at least £25 million in Outcome Delivery Incentive (ODI) rewards in fiscal year 2026.

The ODIs, calculated post-tax in 2022–23 prices, are awarded based on performance against targets set by regulators across environmental, service, and operational outcomes.

Capital investment for the first quarter stood at approximately £360 million. The company reiterated its full-year capital expenditure guidance of £1.7 billion to £1.9 billion. No revenue or profit figures were disclosed.

AMP8, the eighth Asset Management Plan cycle, spans April 1, 2025, to March 31, 2030.

It sets performance expectations for regulated water utilities in England and Wales, including infrastructure investment, customer service, and environmental metrics.

The company did not revise guidance or disclose any changes to its financial outlook in the statement.
