British Gas owner Centrica says its financial performance for the year remains on track, despite losing another 107,000 household accounts.

In a trading update, the company also revealed that it had upped its annual cost savings by £50 million (from £300m to £250m) and will trim planned investment spend by £100m (to around £800m) in an attempt to keep control of the books.

It confirmed annual results – due to be released in February 13 – will be skewed towards the second half of the year, with the result dependent on weather and wholesale energy prices.

And is said the rate of customer losses, which were lower than the first half of the year, when it shed 178,000 accounts, had eased.

Centrica – which has a number of operations in south Cumbria – is already axing up to 2,000 jobs over 2019 as part of overall aims to save £1 billion by 2022, but stressed cost savings made meant there would be no further cuts.

Centrica’s outgoing chief executive Iain Conn, who recently announced plans to step down next year, said he had been encouraged by the drive for efficiency and capital discipline.

“Our performance has been solid so far in the second half of the year and we remain on track to achieve our full-year targets,” he said.

“I am encouraged by further growth in customer accounts and the recovery of business energy supply margins in North America, while we also continue to drive material levels of.”

“Our focus remains on satisfying the changing needs of our customers, providing energy supply and its optimisation, and services and solutions to enable the transition to a lower carbon future.”

The update on the London Stock Exchange comes just a week after Centrica won a court battle with the energy regulator over the way the energy price cap had been calculated.

Centrica had claimed the rules cost the business £70 million in the first three months of 2019, following the cap’s implementation.

It said the decision means Ofgem will now be obliged to “reconsider” the allowance for the first quarter of 2019.

The legal challenge, which was supported by Npower, SSE, EDF, Eon and Scottish Power, could also now result in officials reassessing how the cap is totted up at the next recalculation in February.

In Cumbria, Centrica operates gas terminals situated between Roose and Rampside near Barrow and has operations in Morecambe Bay.

It also operates a 49-megawatt battery storage facility, built on the site of the former gas-fired Roosecote power station in Rampside Road, which is able to come online in less than a second to meet fluctuations in demand and is able to hold enough power to provide energy for around 50,000 homes.
