Smart home devices aren’t just futuristic gadgets, they automate the small habits that quietly waste energy.

Think heating empty rooms, leaving devices on standby, or forgetting to turn things off at night.

Heating a whole room for one person rarely makes sense, but a heated blanket isn’t always the right answer either.

The real difference comes down to wattage, usage time, and how many people need to stay warm.

The Savzz Heated Blanket vs Heating Calculator shows your exact cost per hour for both options, using your blanket’s wattage and your home’s heating setup.

It highlights when a blanket is the clear winner, and when heating is still the better choice for comfort, damp prevention or multiple people.

Most people know their quarterly heating bill, but almost nobody knows the per‑hour cost, even though that’s the number that actually changes behaviour.

Gas heating for a typical UK semi can be anywhere from 60p to £1.20 per hour, while electric radiators cost far more and heat pumps much less.

The Savzz Home Heating Cost Calculator shows your exact hourly, daily, monthly and annual cost, plus a room‑by‑room breakdown, thermostat savings, and a comparison of whether it’s cheaper to leave the heating on or turn it off when you go out.

Smart prepayment meters allow households to add energy credit digitally without using physical cards or keys. Payments can be made through apps, websites, or phone services, and in most cases, the balance updates quickly. However, there are situations where a top-up is completed, but the credit does not show on the meter straight away. This usually relates to how the system communicates rather than an issue with the payment itself.

How smart meter credit updates are delivered

When a top-up is made, the payment creates a digital instruction that is sent to the meter through a secure national network. The meter’s communication hub receives this instruction and updates the balance.

If the update does not appear, the instruction is often still waiting to be delivered. The credit remains connected to the account and is usually applied once the connection is restored. Until then, the meter continues to operate using the existing balance.

Reasons a top-up may be delayed

There are several points within the system where delays can occur.

Signal and connectivity

Smart meters rely on a central communications network managed by the Data Communications Company (DCC). If signal strength is low or temporarily interrupted, the update may take longer to reach the meter.

System activity

At times, energy systems undergo updates or maintenance. During these periods, payments are still processed, but the instruction to update the meter may be slightly delayed.

Display timing

In some cases, the meter has already received the credit, but the in-home display has not refreshed. This can create the impression that the top-up has not been applied.

How manual codes help apply credit

To support situations where automatic updates are delayed, each transaction generates a 20-digit code. This can be entered directly into the meter to apply the credit without waiting for the network.

Across the UK energy sector, suppliers provide access to these codes through different methods. For example, providers such as British Gas may send them by text or email. Access through digital tools is also available with services offered by Octopus Energy, with similar functionality provided by E as part of its smart meter top-up and account management services. These systems help ensure credit can still be applied even when network updates are delayed.

Measures that help prevent disconnection

There are safeguards in place to reduce the impact of delays.

Emergency credit access

Most smart prepayment meters include emergency credit, which can be used when the balance runs out. This provides temporary access to energy while waiting for the update.

Friendly credit periods

During evenings, weekends, and public holidays, meters usually remain active even if credit reaches zero, helping maintain supply.

Regulatory framework

Under Ofgem requirements, suppliers must provide support for customers at risk of disconnection, including alternative ways to apply credit.

Practical ways to manage delays

Keeping a small amount of credit on the meter can help reduce disruption if a delay occurs. It is also useful to keep the transaction code so it can be entered manually if needed.

If you’re switching energy supplier in the UK, Octopus Energy has a refer-a-friend scheme that gives £50 credit when you join through a referral link.

It’s not a voucher or cashback — it comes straight off your energy bill after your first Direct Debit.

I’ve written a straightforward guide explaining how it works, when the credit shows up, and the common mistakes people make:

The UK government has officially selected Wylfa, on the island of Anglesey in North Wales, as the location for the country’s first small modular reactor (SMR) nuclear power station — a major step in Britain’s drive to boost clean energy capacity and strengthen energy security.

The announcement marks a significant milestone in the government’s £2.5 billion investment in SMR technology, designed to deliver low-carbon power more quickly and cheaply than traditional large-scale plants. Each mini reactor will be capable of providing electricity for up to three million homes, with construction expected to create around 3,000 jobs in the region. The new plant is projected to connect to the national grid in the early 2030s.

The government confirmed that Rolls-Royce SMR will supply the technology — a compact reactor design selected earlier this year — as part of the UK’s long-term plan to diversify its nuclear portfolio and reach net zero emissions targets.

However, the move has sparked diplomatic tension with the United States, after the US ambassador to Britain issued a strongly worded statement expressing disappointment over the decision. Washington had reportedly lobbied for an American-led project at the Wylfa site, where a previous nuclear station operated until its closure in 2015.

Despite the criticism, UK ministers defended the choice as a “homegrown solution” that supports domestic expertise and manufacturing. A government spokesperson said the Wylfa project “represents the future of British energy — cleaner, faster, and made in the UK.”

Alongside the SMR programme, the government’s Great British Energy – Nuclear (GBE-N) division has been tasked with identifying a suitable location for a new large-scale nuclear plant by autumn 2026.

Currently, two large nuclear projects are under construction in the UK — Hinkley Point C in Somerset and Sizewell C in Suffolk — both operated by France’s EDF Energy.

Prime Minister Keir Starmer has confirmed that Britain’s first small modular nuclear reactors (SMRs) will be built in north Wales, marking a major milestone in the country’s push for clean energy independence — but the decision has drawn sharp criticism from the United States.

The Wylfa site on the island of Anglesey will host three SMRs developed by Rolls-Royce SMR, backed by a £2.5 billion government investment. The plan is part of Starmer’s wider strategy to revive the UK’s nuclear industry, generate low-carbon power, and create thousands of skilled jobs.

SMRs are compact, factory-built reactors designed to be cheaper and faster to install than conventional nuclear power stations. Each Rolls-Royce unit will generate around 470 megawatts, with production largely based in Derby.

However, the move has sparked a diplomatic rift with Washington. The U.S. ambassador to the UK, Warren Stephens, expressed disappointment that American firm Westinghouse Electric Company was passed over for the contract.

“We are extremely disappointed by this decision,” Stephens said. “There are cheaper, faster, and already-approved options to provide clean, safe energy at this same location. We urge Britain to consider a different path.”

The criticism follows the Trump administration’s recent $80 billion deal with Westinghouse to build several large nuclear plants, a project seen as central to reviving the U.S. nuclear sector.

Despite the U.S. backlash, UK officials defended the decision. A senior government source said:

“This is the right choice for Britain — homegrown clean power from a British company, supporting British jobs.”

The Great British Energy – Nuclear (GBE-N) division will also assess potential sites for future large-scale nuclear plants, with Torness and Hunterston in Scotland reportedly under consideration.

Energy Secretary Ed Miliband said the project symbolizes “a new era of British-made nuclear power” that will help the UK meet its climate goals and strengthen energy security.

The Wylfa site has a long nuclear history — its last reactor closed in 2015, and previous redevelopment attempts, including a Japanese-led project by Hitachi, collapsed in 2019.

In his announcement, Starmer said:

“For too long, places like Anglesey have been let down. This government is reversing that decline — creating good jobs, boosting investment, and securing cheaper, cleaner power for the long term.”

Unions, however, raised concerns. Unite’s General Secretary, Sharon Graham, argued that opting for multiple smaller reactors instead of a single large-scale project could limit job creation.

“Failure to support a gigawatt-scale station at Wylfa would be a missed opportunity for energy security,” she warned.

Industry leaders welcomed the news. Tom Greatrex, CEO of the Nuclear Industry Association, called it “a major opportunity for British technology and skills.”

He added:

“To reach the UK’s energy goals, we need both large and small reactors — and strong partnerships with allies, including the United States, will remain vital.”

Rolls-Royce SMR, partly owned by Qatar’s sovereign fund, BNF Resources, Constellation, and Czech utility CEZ, employs over 1,000 engineers and is advancing plans to export its modular reactors to Europe, including Czechia’s Temelín plant.
