In a bid to reduce reliance on global energy markets, initiatives like Plug-in solar can be a defining turning point towards self-sufficiency, writes Heligan Group.

The conflicts with Iran continue well into March as oil tankers remain stuck in the Strait of Hormuz. However, this is being reflected in wholesale gas prices which have surged across the world. Whilst the UK doesn’t heavily rely on oil from the Middle East, it still buys energy on global markets.

This week, the government announced its initiative to make ‘Plug-in solar’ readily available in the UK high street, naming retailers like Lidl and Amazon, alongside manufacturers such as EcoFlow, that will be working with the government to bring the technology to market.

“Given the recent geopolitical events, the UK’s reliance on global energy markets has become front and centre. The solution lies in a series of short-term initiatives to address the immediate impact of rising energy prices on homeowners,” said Andrew Dickinson, Head of Infrastructure Services at Heligan Group.

“Plug-in solar is one of these solutions that is expected to lower the barriers to entry for homeowners. The previously lengthy process of roof assessment, design and installation by a specialist technician will no longer be necessary.

“Everyday homeowners will be able to buy plug-in panels to supply energy to the grid through a house’s mains supply. This initiative builds on a broader suite of plans that includes floating infrastructure, offshore cable development and new nuclear capacity (including small modular reactors) to help the UK achieve energy self-sufficiency.”

The announcement follows January’s statement committing £15 billion under the ‘Warm Homes Plan’, to bring up to one million families out of energy poverty.

“Plug-in solar panels were not previously permitted due to concerns about overloading the circuit and inverters that did not comply with UK standards, creating a risk of overheating and fire.

“New safety standards, including power limits and approved inverters for manufacturers, will reduce these risks to an acceptable level. The availability of such appliances will contribute to the goal of significantly cutting energy bills.”

Dickinson points out a key aspect of the government’s announcement relating to developers fitting solar panels and heat pumps to all new homes, which will reduce energy reliance on gas.

“The plug-in solar panel initiative works hand in hand with electric heat pumps. From 2028, no new homes will be connected to the gas network and will be required to have roof-mounted solar panels covering an area equivalent to 40% of the ground floor space.

“Electric heat pumps will reduce dependency on gas by absorbing heat from outside air, compressing it to raise the temperature, before using a heat exchanger to transfer heat into radiators and underfloor systems.”

Over time, Dickinson believes there is potential for these initiatives to change how the grid is used and reevaluate the infrastructure that is needed.

“Traditionally, electricity has flowed one way, but if homes are increasingly supplying energy back to the grid, further work on grid capacity will be needed. However, there is a mismatch in supply and demand to get ahead of.

“Where summer reduces use of heat pumps and produces higher yield from solar panels, winter will have an opposing effect. As such, electricity sales and demand curves will constantly fluctuate.”

Dickinson continues, “There is likely to be a broader knock-on effect on the utilities market and the creation of alternative business models which support smarter grid management. These include an increased adoption of smart meters, real time voltage control, dynamic tariffs, AI forecasting tools and automated response systems.

“This could be great news for MEP contractors and specialist service providers, particularly as there are signals that similar government initiatives can be expected for commercial and industrial energy consumption.”

Dickinson concludes, “Announcements like today’s approach to plug-in solar are unlikely to be impacted by such issues, but this initiative alone is not enough. In 2025, there have been  delays in major projects, often held up by decisions delayed by legal challenges and deteriorating project economics. If it remains unhindered by bureaucracy, energy infrastructure goals have the potential to impact upon the UK’s national security and be successful within markets.”
