**Households Urged to Keep Windowsills Clear Amid Escalating Summer Fire Risks**
Residents across the UK are facing a stark warning to ensure their windowsills and gardens are clear of potential fire hazards as hotter, sunnier conditions set in this summer. The call to action comes after a surge in fire-related insurance claims this spring and growing concern over the changing climate’s impact on fire safety in homes and outdoor spaces.
Recent data released by Aviva, one of the country’s major insurers, has revealed an uptick in claims for garden and outdoor fires during the months of April and May—months that have already eclipsed the previous records set in 2024. These incidents, according to Aviva, can be costly, with the average claim amounting to almost £16,000. The figures signal a trend likely to continue as the UK basks in record levels of sunshine, clocking 630 hours nationally between March and late May—more than any spring on record.
Analysts suggest the increase in fire claims is linked not only to the prolonged period of sunshine, but also to a rise in outdoor activities such as barbecuing, bonfires, and garden gatherings. While these activities are a staple of British summertime, they also carry inherent risks. Aviva’s findings indicate that even seemingly benign actions—like leaving glass objects on windowsills or hanging decorative mirrors in the garden—can have unintended consequences under the magnifying effect of strong sunlight.
Further compounding the issue, the insurer also noted a rise in lightning-related claims over the past five years, with electrical storms causing fires by igniting roof spaces or compromising the safety of mains-powered devices. In a survey conducted among 2,000 UK adults, 12% admitted thinking more about fire safety when the weather turns hot, and 13% expressed heightened concern during periods when barbecues are commonplace.
Examples of recent claims highlight just how quickly situations can escalate: a stray ember from a barbecue led to a shed fire, ash from backyard fire pits ended up causing damage to garages, and bonfires have been responsible for the complete destruction of garden structures, from decking to fences.
Commenting on the issue, Hannah Davidson, a senior manager at Aviva, stressed the importance of vigilance as householders enjoy the warm spell. “While we all look forward to spending more time outside during the summer, it’s crucial to be aware that drier conditions can help fires spread with alarming speed—particularly where gardens contain flammable materials,” Davidson explained. She suggested residents review their gardens and windowsills for items that could exacerbate a fire, such as discarded glassware or poorly stored outdoor equipment.
Aviva’s recommendations for minimising fire risks are both practical and urgent. Garden bonfires should be avoided where possible, especially during dry spells or windy days, as these conditions can result in fires getting out of control. If a fire must be lit, it should never be left unattended, and residents are advised to keep water or a hosepipe nearby at all times. Similarly, fire pits and barbecues should be used with caution—with disposable barbecues placed only on non-flammable, heat-resistant surfaces well away from fences or sheds.
The company also urges residents to be mindful of electrical hazards. Overheated lithium-ion batteries—found in many common tools and devices—have the potential to catch fire, so users are reminded to unplug appliances once they are fully charged and to refrain from leaving devices charging overnight or unsupervised. Reflective objects, particularly mirrors and bottles on windowsills or in gardens, should be kept out of direct sunlight to avoid the risk of fires being triggered by concentrated rays.
Additionally, the careless disposal of cigarettes remains a significant cause of accidental fires in dry conditions, with Aviva urging smokers to ensure cigarettes are fully extinguished and disposed of responsibly.
As Britain heads into another bright and potentially hazardous summer, the message is clear: a few simple precautions now could spare homeowners from serious damage—and a hefty financial hit—later. With climate patterns shifting and warm, dry spells becoming more frequent, staying vigilant and taking preventative measures is more important than ever.
