UK GAS-Prices rise as coming cold wave seen lifting demand

LONDON, Nov 11 (Reuters) - Britain's wholesale gas prices rose on Monday due to expectations for colder weather and consequently higher demand in coming days, with stronger carbon also lending support.

* The December gas contract was up 0.39 pence at 42.28 pence/therm.

* Expectations for colder weather in coming days were behind the rise in prices, gas traders said.

* Demand is seen much higher on Tuesday, a gas trader said, at 308 mcm/day.

* The benchmark Dec-19 EU carbon contract rose by 0.54 euro to 25.38 euros a tonne.
