* FTSE 100 down 0.1%, FTSE 250 off 0.6%

Feb 1 (Reuters) - Britain's main stock indexes slipped on Thursday, tracking overnight losses on Wall Street, as investors scaled back bets of a U.S. interest rate cut in March, although shares in BT Group and Shell helped limit losses in the FTSE 100.

Shell climbed 1% after the energy major increased its dividend by 4% and extended its share repurchases despite reporting a drop in 2023 profit.

Shares of BT gained 4.1% after Britain's biggest broadband and mobile operator said it was on track to grow revenue and profit this year after reporting a better-than-expected third-quarter revenue.

The blue-chip FTSE 100 slipped 0.1% by 0809 GMT, while the midcap FTSE 250 dropped 0.6%.

Both the FTSE indexes closed out January with their worst monthly performance since October 2023, as investors reined in bets of aggressive interest rate cuts this year.

Wall Street closed sharply lower on Wednesday after the U.S. Federal Reserve held interest rates steady while dashing hopes for a cut as soon as March.

Britain's central bank looked set to keep interest rates at their highest levels in nearly 16 years later on Thursday, with investors looking for hints of potential rate cuts later this year.
