Arthur Downing, author of Power and the People: A History of British Energy, says all-encompassing rapid transition will need a mutualised system

Have you ever wondered why it is that most houses in the UK are reliant on gas boilers? Not what’s stopping more people from replacing them with heat pumps, but instead why and how the gas boiler became so ubiquitous in the first place?

Arthur Downing, the author of the new book Power and the People: A History of British Energy, can tell you exactly why. “We only have boilers in our houses because of a state-owned enterprise that went into everybody’s home and installed natural gas-suitable appliances at no direct cost,” he says. The nationalised gas industry of the 1940s to the 1980s, which oversaw this huge project, was for three decades one of the “most dynamic, innovative, efficient industries in Britain”, Downing says. Yet few of us would use these terms to describe it as such now.

Savings grow as energy prices in Great Britain rise and cost of panel installation falls, analysis finds

Households in Great Britain’s cloudiest regions could still save more than £400 a year on their energy bills by installing rooftop solar panels, research has found.

Rising wholesale energy prices mean the potential savings from a home solar panel system have climbed in recent years, as the cost of installation has continued to fall, leading to increased demand.

A financial model that could cut the cost of installing solar panels for many homeowners is welcomed by Alexis Abramson

The UK proposal to use “solar bonds” to make rooftop solar more affordable is a smart solution to a fundamental problem: the rising cost of capital (Cut cost of loans for solar panels on UK homes, ministers urged, 21 August).

A household that can pay for solar upfront saves money from day one. For everyone else, high-interest financing can consume much of those savings and ultimately deter people from installing the technology. A solar bond structure changes that equation: investors receive a modest, guaranteed return, and homeowners get access to cheaper capital. Because the loan is attached to the property rather than the individual, there’s no issue if the person moves.

As well as being quieter, cheaper to run and easier to clean, induction cookers can cut kitchen temperatures by up to 10C

Leaping flames, searing heat, copious sweat and scorchingly inventive swearing – restaurant kitchens are never a place for the faint-hearted, but this summer they have been sweltering in successive heatwaves to a dangerous degree.

Some restaurants, cafes and bakeries in the UK grew so hot that they were forced to close, or reduce their hours, for the safety of their staff. There is still no maximum working temperature, despite calls from the TUC, and tens of thousands of kitchen staff are thought to have carried on working in “furnace-like” conditions.

Soaring prices are plunging struggling families into debt. The government must support them in the short term as it invests in a clean energy future

Fuelled by the consequences of Donald Trump’s disastrous war on Iran, household energy debt in Britain is continuing to soar, rising to a record £6bn by the end of June. That figure is set to hit £7bn by the end of the year, as the government’s cap on gas and electricity prices goes up to a three-year high in October. The human cost among the less well off will be more people regularly choosing whether to skip meals, ignore other bills or stay cold this winter.

Such is life at the sharp end of the cost of living crisis, which Andy Burnham has made it his priority to address since arriving in Downing Street. The day after he became prime minister, Mr Burnham announced that VAT would be removed from electricity bills from the beginning of October. But the Middle East-related rise in the price cap, announced on Wednesday, more than wipes out the effect of his cut. In an era of geopolitical volatility, high energy costs have become the new normal.

Colin Hines says Andy Burnham’s focus should be on drastically cutting fossil fuel use in a way that reduces bills and generates secure jobs

It is hardly surprising that many who were optimistic and supportive of Andy Burnham becoming prime minister, but who also prioritised tackling climate chaos, are becoming increasingly unsure about him, given his tardiness in emphasising this threat as an overriding policy objective (Labour ‘could lose up to 50 seats’ to Greens if new drilling in North Sea approved, 19 August).

One of the problems he faces is that the political debate around energy is obsessed with relatively short-term fossil fuel supplies. Instead, the focus should be on drastically and rapidly cutting fossil fuel use in a way that reduces bills and generates secure jobs through a devolved energy programme for every postcode.

Farms and rooftop panels contribute 14.4% to the grid – and figures reveal a surge in new installations

Solar energy supplied more power to Great Britain’s grid in July than in any previous month as households turned to rooftop panels to cut their energy bills.

Solar farms and rooftop panels provided 14.4% of the country’s electricity after some parts of the UK recorded almost twice the average sunshine hours for the time of year.

CEO Chris O’Shea defends Centrica’s plans as it reports rise in retail profits following focus on bigger margins

The owner of British Gas has claimed that most households would rather speak with an AI chatbot than deal with the company’s staff as it prepares to cut 1,300 jobs from its call centres and back office.

Centrica, the supplier’s FTSE 100 owner, plans to cut 800 jobs as the company carries out a “targeted deployment of AI tools”, on top of the 500 cuts it confirmed last month.

Law change means renters and flat owners may be able to cut bills as energy costs soar amid Iran war

British households will be able to buy plug-in solar panels later this summer after the government changed the law so the UK’s biggest retailers could bring them to market for the first time.

People across the country will be able to join the millions across Europe generating their own electricity using “balcony solar panels” from 27 August, according to legislation passed last week.

New Economics Foundation and Finance Innovation Lab suggest loan scheme backed by Bank of England could benefit up to 8m homes

Millions of UK households could save hundreds of pounds a year on their energy bills if the government were to approve low-cost loans for solar panel installation, research has found.

Solar panels with batteries are one of the cheapest ways to generate electricity and reduce energy bills, but with an upfront cost of about £6,000 they are still beyond the reach of most cash-strapped UK households while other countries forge ahead with installation.

For months I’ve been trying to receive my FIT payment, which should be more than £1,000

I moved into my new house 14 months ago, and soon afterwards applied to ScottishPower, with whom the solar panels are registered for a feed-in tariff (Fit), for transfer of ownership of the panels and the tariff.

After many emails back and forth, I got a response saying they had all the information required.

Asda, Amazon and B&Q among retailers in talks to sell devices that feed into household sockets and can cut electricity bills by 30%

• Spanish homes save €10 a month via renewables expansion

Bosses of some of Britain’s biggest retailers are discussing plans with the government to start selling plug-in solar panels as part of a drive to encourage more UK homes to generate their own electricity.

Executives from brands including Currys, B&Q and Amazon met Martin McCluskey, the minister for energy consumers, on Tuesday to discuss guidelines for selling “balcony solar panels” to the British public.

Cllr Lucy Shaw says councils could take up many policies to help, including more support for rooftop solar installations

Your editorial is right that the government could be doing more to help with the cost of living (The Guardian view on Britain’s coming energy shock: mini-measures won’t suffice, 22 May). That extends to local government, too. Renewable energy projects, from the industrial scale right down to rooftops, can be scuppered locally even if there is national support. The wealthiest borough in the entire country, Kensington and Chelsea, has the nation’s lowest rooftop solar installation rate, at just 0.6% of households according to the MCS installer database. This is despite touting groundbreaking policies to make it easier to build solar in conservation areas.

There are so many local policies that would help. Coordinating solar installations by street could lead to material cost savings, as would simpler permitting rules, and installations on council-owned rooftops. When 80% of cars in the borough are parked on the street, cost-effective public charging is essential to ensure that drivers can make the switch, like offering discounted charging when grid power is cheapest. Partnering with housing associations, charities, and energy suppliers to help people access energy efficiency services and government capital grants, or negotiate payment plans for their bills could go a long way to making people feel more secure.

Regulator could do us all a favour with clear multi-year forecasts and breakdowns of electricity pricing

It is easy to predict where the energy regulator will set the next quarterly price cap on Wednesday. It’s just a matter of tracking wholesale prices in Ofgem’s relevant backward-looking “observation period”. Energy consultant Cornwall Insight thinks the typical household bill be £1,850, an increase of £209 from the previous quarter. It will be surprising if it is out by more than a few quid.

One can also make a fair guess at the regulator’s messaging. It will talk about the unavoidable impact from the surge in energy prices that followed the closure of the strait of Hormuz. It may also say the increase would be even greater than 13% without the additional wind and solar generation on the system these days. Fair enough. Gas sets the wholesale price of electricity only 60% of the time now, down from 90% not long ago.
