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…

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…

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…

How on-demand transport will support an ageing UK population

Designing cities for the future: the changing cost of independence The way we move around our towns and cities is going to change dramatically over the next 20-25 years. Ageing populations, technology shifts, climate pressures and rising costs will reshape not only how we travel, but how our neighbourhoods function. For millions of people, mobility is more than a practical question - it is the foundation of independence, dignity and community life. For years, the sustainability debate has been dominated by discussions about vehicles: EVs, emissions standards, charging infrastructure, and the decline of the combustion engine. Yet the real transformation…

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…
