UK Net Zero Momentum Stalls as Councils and Retrofit Fall Behind

Welcome to Net Zero News, your daily briefing on the UK’s transition to a low‑carbon future.

A new assessment has sounded the alarm on the pace of local climate action, revealing that UK councils are making only modest gains in their journey towards net‑zero, with the average council score rising a mere six percentage points between 2023 and 2025 up to just 38%. Only 16 percent of councils are currently on track to meet their self‑declared 2030 targets, underscoring the widening gulf between ambition and delivery at the local level. Most councils still fail to address critical areas such as retrofitting homes, improving public transport, and expanding green infrastructure even though these areas are vital to reducing emissions and adapting communities to climate impacts.

Meanwhile, heating retrofit efforts remain severely underwhelming. The Energy Security and Net Zero Committee has identified a deep retrofit deficit: fewer than 3 percent of homes are connected to low‑carbon heat networks, under 1 percent feature heat pumps, and the vast majority are poorly insulated. Of all the homes to be occupied by 2050, 80 percent already exist yet retrofit rates are lagging dramatically behind the 2010 trajectory. As a result, hundreds of thousands of homes may face mortgageability issues due to inadequate energy efficiency standards.

Against this backdrop, the Climate Change Committee (CCC) has published its new pathway under the Seventh Carbon Budget, charting the UK’s route to 2050. The report programmes an 87 percent emissions reduction by 2040 against 1990 levels, with electrification including electric vehicles, heat pumps, and a decarbonised power grid accounting for 60 percent of total reductions. Surface transport alone is forecast to deliver 27 percent of the reduction, while electricity supply contributes 12 percent, and aviation accounts for 5 percent. Altogether, energy use in buildings and other sectors pushes the total to over half of the required reductions.

The CCC also notes the broader co‑benefits of decarbonisation: household energy bills could fall by around £700, matched by similar savings in driving costs. Crucially, most of the investment will be delivered by the private sector, with public expenditure kept below 2 percent of overall annual spending.

In a bid to ease the delivery burden on local authorities, UK Power Networks, Cadent, and SGN have collaboratively launched a “Common Ask Template,” standardising information requests for net‑zero projects. This innovation aims to reduce administrative duplication and accelerate the planning, permitting, and deployment of low‑carbon infrastructure, as demonstrated by pilot usage in Hounslow and across the Greater London Authority’s Outer East London local energy planning area.

What this means:
These findings together paint a sobering picture of the current UK net‑zero landscape. While national strategy and infrastructure innovations are emerging, significant gaps at the local level are slowing progress. The limited improvement in council climate action scores demonstrates that many local governments lack the capacity or resources to match their stated ambitions.

Meanwhile, retrofit shortfalls represent a systemic failure a barrier that undermines progress in almost every emission‑intensive sector, from homes to transport. The CCC’s pathway offers a vital roadmap, but achieving its targets hinges on rapid, widespread adoption of electrification and energy efficiency measures.

The introduction of tools like the Common Ask Template is promising it demonstrates how collaborative, practical solutions can ease implementation and pave the way for faster decarbonisation. But such mechanisms must be scaled across the UK, paired with strengthened funding and support for councils to accelerate action.

Unless progress significantly accelerates, the UK risks falling behind both its ambitions and intermediary goals compromising its ability to deliver cost savings, energy security, and a fair transition for all.
