The PRL Guide to the 2026 Warm Homes Plan

The "Rooftop Revolution" The landscape of British home energy has undergone its most significant shift in a generation. In late January 2026, the government officially launched the Warm Homes Plan (WHP), a landmark £15 billion investment, designed to transform five million properties into energy-efficient, low-carbon homes by 2030. For homeowners, this isn't just another environmental target - it is a comprehensive financial package aimed at permanently slashing energy bills, with some households expected to save up to £850 a year. Designed to fit homes of all sizes, the 2026 plan introduces a "universal offer" of grants and loans that finally removes the massive…

UK housing: embracing insulation innovations

Why Bio-Insulation leads the way For decades, the standard approach to keeping a British home warm has involved rolls of itchy glass wool, or thick slabs of rigid plastic foam. While effective at trapping heat, these materials carry a heavy "carbon debt" from their intensive manufacturing processes. However, a new wave of Bio-Insulation Innovation is hitting the UK market. Leading the charge is WheatEx, a pioneering UK-developed insulation board made from agricultural by-products. For homeowners looking to slash energy bills while lowering their environmental footprint, these plant-based materials are a game-changer. The problem with traditional insulation Most UK homes rely on mineral wool…

The Future of Retrofit: what to expect in 2026

Home Energy Efficiency: Trends for 2026 As we move into 2026, the UK home renovation landscape is no longer driven solely by aesthetics, or by adding extra living space - instead, a more urgent priority has taken centre stage: retrofitting for energy efficiency. With the UK government's Net Zero 2050 targets looming and energy bills remaining a significant concern for households, 2026 is set to be the year that "green" upgrades become mainstream. The introduction of the massive £15 billion Warm Homes Plan is shifting the focus from sporadic, small-scale improvements to holistic, whole-house retrofits. Whether you are looking to…

2025: the second-hottest year since records began

A landmark year 2025 is shaping up to be another landmark year in the climate record. Globally it is on track to be the joint second warmest year ever measured, while the UK is likely to log its warmest year since records began. For householders, that is not an abstract statistic, but a signal to rethink how homes are heated, cooled and protected from floods and storms through intelligent retrofit. A year that confirms the trend The global climate story in 2025 is one of persistence rather than surprise. The planet is not just warming in occasional spikes; it is settling into…

Electric cars are going the distance

Sustainable technology is leading the way There's a new spark of good news in the world of sustainable technology - and this time, it's about how long our vehicles are lasting. A recent study published in Nature Energy has found that electric vehicles (EVs) nearly match petrol cars in lifespan and comfortably outlive their diesel counterparts. On average, electric cars now last 18.4 years, compared to 18.7 years for petrol models and 16.8 years for diesels. For years, one of the quiet reservations surrounding EVs has been longevity - particularly the durability of their batteries. Would electric cars stand the test of time, or would early adopters…

Why Lüften brings relief in the midst of winter

Keeping warm and staying healthy: why we need a winter ventilation rethink The UK is in the grip of freezing temperatures, with overnight lows falling well below zero. Windows are shut tight, draughts are blocked and everyone is trying to keep the heat in. It's an understandable instinct as heating costs are high, and homes lose warmth quickly. But, while closing everything up feels sensible, it brings a dangerous consequence: damp, condensation and black mould. As we heat our homes but reduce ventilation, indoor air becomes humid and stale. Hidden moisture settles on cold walls and windows, and, in the…

Retrofit and decarbonisation: it’s time to rethink the route to scale

Retrofit with purpose: rethinking decarbonisation and design Across the UK, the call for mass retrofit grows louder by the month. Buildings account for around 40 per cent of our carbon emissions, and if we are serious about meeting net zero targets, large-scale retrofit is non-negotiable. Yet despite the ambition, the path we are currently paving could make true scale impossible. From May 29, 2025, new rules in England require all new Air Source Heat Pump (ASHP) installations to comply with the MCS 020a standard, but the new rules will not come into effect until May 29, 2026. From this date, all air source…

Why the UK’s new-build towers are becoming summer ovens

Life inside a heat trap As we discussed in a previous Blog Post, groups of tall buildings are prone to the Urban Heat Island (UHI) effect - which happens because materials like concrete and asphalt absorb and retain heat. A recent headline caught our eye. It refers to what happened last June when a warning was stuck to the window of a flat in Leaside Lock, East London, reading: "DO NOT BUY THESE FLATS. TOO HOT." The photo has been shared over half a million times: Picture Credit: Aidan Sheehan Twelve months later, after the UK recorded its second-warmest June and…

On the brink: why climate resilience can’t wait

The UK's weather is no longer just 'unpredictable' The UK's relationship with weather has long been one of mild fascination, but the days of gentle unpredictability are fading fast. We are now firmly in the age of climate disruption - and it's getting worse. From overheating cities to flash floods, droughts, wildfires, and infrastructure failures, the UK is no longer insulated from extreme weather. These events aren't 'one-off's' either - they're part of a volatile new normal. What we are seeing are climate 'whips' (hydroclimate whiplash) - sudden swings between extremes, such as torrential downpours following long dry spells, or…

The UK is helping oil and gas workers switch to green energy careers

The winds of change Around 90 per cent of fossil fuel workers have skills that are relevant to the clean energy transition. The winds of change are indeed blowing across the UK, as it embarks on an energy transition that is both good for the economy and essential to curbing climate change. Homegrown wind and solar are taking over from fossil fuels, but it's important that workers aren't left behind. Job losses are occurring in the oil and gas industry at an astonishing rate, with some reports indicating potentially significant reductions in the workforce. A report by Robert Gordon University suggests that the UK could lose…
