20 tips to help beat the heatwaves this summer

Keeping healthy - no matter the weather As summer temperatures soar across the UK, keeping your property comfortable is becoming a major priority. As climate change continues to drive record-breaking summers and extreme heat warnings, the way we think about our homes is undergoing a massive shift. Historically, British homes were built to trap heat and keep out the bitter winter cold. However, in recent times, an uncomfortably hot house is no longer just a minor annoyance; it can be a serious health hazard. At PRL, we know that true energy efficiency is about year-round comfort. A well-retrofitted home is…

PRL’s comprehensive guide to setting retrofit priorities

Getting the balance right With the UK's commitment to reach Net Zero, retrofitting your home has never been more vital. This Blog explores the essential factors to consider when setting your retrofit priorities. You will need to balance energy efficiency, cost-effectiveness, and environmental impact, to create a 'cool in summer/ warm in winter', more sustainable, and future-proof home. The retrofit imperative for UK householders The UK housing stock is famously characterful, yet equally notorious for its age and energy inefficiency. With millions of homes requiring substantial upgrades before the government's Net Zero targets, retrofitting can adapt a property to improve its…

Underfloor heating: low-profile, low-disruption comfort

Retrofitting underfloor heating: a rapidly growing trend For decades, the idea of underfloor heating (UFH) in the UK was deemed a luxury reserved exclusively for new-build homes, or major extensions. Older, period properties - from Victorian terraces, to 1950s semi-detached homes - were traditionally limited to radiators, often struggling with uneven heat, limited wall space, and high energy bills. Thankfully however, the tide has turned. Retrofits of underfloor heating are in high demand, driven by advancements in technology that make it possible to install modern, high-efficiency UFH systems without ripping up existing floors or destroying the character of older homes.…

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…

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…

2024 was a chaotic weather year

The effects of climate change are becoming more evident 2024 was a record-breaking year for extreme weather in the UK. Storms and floods caused an unprecedented level of damage to homes and businesses, leaving many homeowners facing costly repairs and insurance claims. Heavy rainfall, high winds, and flooding were more frequent and severe. With climate risks intensifying, homeowners can no longer afford to be reactive. Instead, proactive measures like retrofitting offer a long-term solution to protect properties against extreme weather. Retrofitting homes with better insulation, flood resistance, and storm-proof features is not just about avoiding damage - it is about…

Keeping your home cosy and energy efficient as the nights draw in

How to prepare for an energy-efficient autumn/winter season As the cooler months set in across the UK, there's no better time to ensure your home is ready to combat the autumn and winter chill. Retrofitting an older home with energy-efficient upgrades not only helps to keep it warm, but also reduces heating costs and carbon emissions. The benefits of an energy-efficient home A well-prepared home is vital for enduring the colder months, and retrofitting can yield multiple advantages: Lower Energy Bills: efficient insulation and heating systems reduce reliance on constant heating, keeping bills manageable. Increased Comfort: insulation and draught-proofing retain…
