SUMMARY

We have seen high levels of price volatility this past week with the market still struggling to settle on a clear direction due to an uncertain winter outlook.

The winter supply season officially begins next Thursday, and Europe will enter it with storage still well below normal for the time of year. Ongoing Qatari LNG cancellations into November and an only partially reopened Strait of Hormuz has left little margin for error.

Speeches by US and Iranian leaders at the UN General Assembly earlier in the week also did little to ease tensions or signal an imminent end to the 7-month conflict, which has significantly impacted global energy flows.

Softer wind output also lifted gas-for-power demand slightly, coupled with imports from Norway remaining severely constrained by a combination of planned and unplanned maintenance.

Baseload power prices followed the gas trend for the majority of the week as renewable and gas fired power each generating the same amount of electricity.

Say 'No' to cold calling on business energy

Unfortunately, business electricity and business gas customers in the UK are bombarded with unsolicited cold calls on a daily basis.

This unscrupulous approach does not offer the business energy customer an impartial view on the market and the price offered is more often 20-30% above the current retail price for electricity or gas.

At Energy Advice Line we strongly advise customers to not accept these offers and follow our simple steps to ensure that they are not locked into an uncompetitive contract.

Join our cold calling campaign here, and spread the word to say 'no' to cold calling on business energy!
