When it comes to emissions reductions, it is still widely recognised that energy efficiency is the ‘first fuel’ en route to net zero because it is one of the quickest and most affordable ways to cut emissions. However, new research has shown that 95% of companies globally do not have energy efficiency plans in place.

Having worked with many UK organisations, I know first-hand that as a nation we’re doing better than most thanks to the growing body of legislation mandating organisations to audit, plan, and report on their actioned energy efficiency measures.

Although these can be time-consuming, they are necessary. By using energy wisely, at the right times, with the right technology, and transforming our buildings to eliminate waste, organisations can save money, protect themselves from energy price fluctuations, and reduce their emissions.

Such changes can form the backbone of their carbon reduction plans. As supply chain emissions increasingly determine purchasing and investor decisions, not reducing emissions effectively removes organisations from buyers’ and investors’ considerations.

As 2024 comes to a close, Kier Starmer has accelerated the UK’s journey towards net zero by 2050. Over the next ten years, the UK must now reduce its emissions by 81% compared to 1990 levels.

Energy efficiency will continue to play a central role for UK organisations on this new pathway, alongside bill management and carbon reduction planning. To find out what the first year on this new trajectory will be like for businesses and how they can navigate it, I spoke to some of our energy management and carbon reduction experts, starting with Tim Holman, Head of Operations at TEAM Energy.

What does the new Government mean for energy efficiency, have there not been rumours of the energy efficiency standards changing?

Through a parliamentary question reply in December and at the Labour Party conference in October, the Government suggested that minimum energy efficiency standards for commercial buildings would increase, possibly from an E to C rating by 2030. Though not certain, any changes could be announced in the new year. However, more concrete is the Energy Performance of Buildings (EPB) framework consultation, which opened on 4th December 2024 and will close in February 2025, with changes set to be implemented from early 2026. This could introduce reduced validity timescales below 10 years for Energy Performance Certificate (EPC) and Display Energy Certificate (DEC) (for smaller buildings <1000m2) as well as requiring EPCs to be valid at all times, making them a more frequent requirement for commercial landlords and a necessity for re-letting and lease renewals.

Alongside this could be changes to what EPCs measure with new and amended metrics. These potential changes could lead to the implementation of substantial energy efficiency measures sooner rather than later.

I would advise any landlord to get ahead of the curve and ensure now that your buildings and workplaces are ready for energy efficiency improvements. Failing to do so could lead to a loss of revenue or missing out on securing finance dependant on EPC ratings, for example.

The exact details of the Minimum Energy Efficiency Standards changes are far from certain, neither have the ESOS deadlines been. So, I spoke with Senior Energy Consultant, Sam Arje to help shed light on the situation.

The ESOS deadlines have shifted a lot, what does 2025 look like for businesses?

The start of the year will see organisations still submitting their ESOS phase 3 action plans, past the December deadline due to the Environment Agency’s (EA) promise to accept late submissions until the 5th March 2025. Hopefully those organisations who have completed their phase 3 audits have already prepared their action plans in full. Crucially, ESOS action plans must strike a balance between committing to meaningful action and not overshooting what’s possible, especially now the plans and progress reports against them will be made public.

Organisations must act with their reputations and competitive advantage at the forefront of their minds, which will require more collaboration throughout the organisation and a shift towards a holistic energy management programme rather than focusing simply on the four-year cycle. As Phase 4 (which runs from 6th December 2023 until 5th December 2027) auditing begins, a holistic energy management approach will help support their now-required net zero planning and actions too.

2025 will be the start of Market-wide Half-Hourly Settlement (MHHS) too. To find out more about both sides of the coin, I asked Head of Business Change, Greg Armstrong his opinion.

As we’ve seen there are regulatory changes for energy efficiency ahead. What about energy markets?

From April 2025 onwards, energy suppliers will begin to migrate their systems and transition their customers to half-hourly bill settlements. This is predicted to create a ‘data deluge’ for energy suppliers, leading to a sharp increase in the potential for organisations’ energy bills to contain errors over the short term. Energy management and bill validation can address this issue. But the bigger opportunities are the tariffs and the unprecedented level of power that energy-users can unlock using accurate energy data. Suppliers must be commercially sensitive to 30-minute windows of energy use, energy users with the right data will have every opportunity to benefit from that.

Processing that data will be an energy cost itself, and much of that task is done by AI. Tom Anderton, Head of Customer Success at TEAM Energy, provided his insight on this issue.

How will data and AI impact energy and net zero? We’ve heard a lot about the energy drain from AI – Tom, what do you think about that?

The challenge of energy security and net zero must be tackled with varied tools, prime among these are AI and big data. 2025 will see an uptick in both. We’ve just seen the launch of the Manchester Prize encouraging start-ups and tech entrepreneurs to decarbonise the grid in the UK, and COP 29 had its first ever ‘digitalisation day’. In their own organisations, energy managers can use AI and data to get better insights into their energy estate, reduce their emissions, and mitigate the risks of energy security and climate change.

On a larger scale it’s true that data and AI have energy costs associated with them, but they’re often exaggerated, accounting for one or two per cent of energy use based on the International Energy Agency (IEA) figures. Compared to buildings, for example, that’s a small figure. And, importantly, the increase in AI can also help counter building energy use; so the small percentage increase incurred is made up for in savings.

Whatever energy and emissions savings organisations make must now be reported, in detail, and to the public. Rob Webb, Bureau Operations Manager, lending his expertise on this topic.

Increasingly many companies are now in the scope of sustainability reporting. What do they need to be mindful of when it comes to data, Rob?

We’ve now reached the ‘tipping point’ where sustainability reporting, including energy and carbon reporting, is mandatory and the primary form of nonfinancial reporting driving investor decisions. Because of this, the expectations around the accuracy of organisations’ reporting have increased massively, causing almost all CFO and finance leaders to report problems with the nonfinancial data they receive.

Visibility, consistency, incompleteness, and out-of-date data are the top issues such leaders face. Organisations must adopt smart systems to eliminate “single point of time” data, search for interoperable tools that can connect to organisation-wide BI and management systems, and seek out expert support to get the right solution in place.

So, in conclusion, 2025 has many deadlines and key dates that organisations need to be prepared for. Acting now will enable them to make small steps towards better energy management, carbon reduction, and overall integrated reporting. Leaving it too late will be costly, the benefits will be lost, and key deadlines could have passed by. As we’ve seen, many organisations will be under more scrutiny in 2025 and beyond too. All stakeholders expect accurate sustainability reporting, and more of organisations’ complex emissions and energy reduction planning will be made public.
