There's a trick to announcing trade agreements like the one unveiled by the prime minister on Monday: pluck out a big-sounding number and release it to the public with zero context in an effort to make this sound very impressive indeed.
Energy bills are set to fall from this July and will continue to drop in the autumn and winter, a forecaster has said.
Households will be charged £129 less for a typical annual bill from July as the energy price cap is due to fall, according to energy consultants Cornwall Insight.
From July, an average dual fuel bill will be £1,720 a year, 7% below the current price cap of £1,849 a year.
The price cap limits the cost per unit of energy and is revised every three months by the energy regulator Ofgem.
The official announcement from Ofgem will be made on Friday.

Bills had already been made more expensive for three three-month periods, or quarters, in a row, in October, January, and April, as wholesale gas prices rose and European stores of the fossil fuel were depleted due to cold weather.

Electricity prices are tied to gas prices.
The UK is also heavily reliant on gas for home heating and uses a significant amount for electricity generation.
Drops when the cap is next changed in October and January will be "modest", Cornwall Insight said.
Price falls are not a certainty, however, as weather patterns, gas storage rules, the war in Ukraine, and tariffs could all change pricing.

Bills still high since Ukraine war
Energy costs have remained elevated following Russia's full-scale invasion of Ukraine, and bills are still "well above" the levels seen at the start of the decade, said Cornwall Insight's principal consultant, Dr Craig Lowrey.
"Prices are falling, but not by enough for the numerous households struggling under the weight of a cost-of-living crisis.
"As such, there remains a risk that energy will remain unaffordable for many," he said.
"If prices can go down, they can bounce back up, especially with the unsettled global economic and political landscape we are experiencing. This is not the moment for complacency."

The government was called on by Mr Lowrey to explore options such as social tariffs, where vulnerable customers could pay less.
Proposals, including zonal pricing, which would see different regions of the country pay different rates, based on local supply and demand levels, are important but must be balanced with the urgent affordability crisis people are facing now, he said.

The continued growth of domestically produced renewable energy is "a positive step forward" and a cause for optimism as it helps protect against global energy price shocks and improves energy security, Mr Lowrey added.
"That progress needs to continue at pace, not just for the net zero transition, but to help build a more stable and secure energy future for all."
