Experts have warned that rat infestations could hit property values and jeopardise sales this winter.
Industry figures and pest-control specialists have signalled a likely increase in rodent activity, citing the unusually hot summer, takeaway culture and ageing infrastructure as factors that create ideal conditions for larger rodent populations.
Kieran Sampler, founder of the Yorkshire Rat Pack, told The Telegraph: ‘It is going to be a bad winter for rats, and people don’t realise…there is always going to be a bad winter after a good summer.’
Homeowners are being urged to tackle rat problems as experts warn infestations could reduce property values, derail house sales and, in some cases, affect insurance cover.
Potential financial impact of rat infestations
Analysis from insurance experts Quotezone.co.uk suggests rat infestations can knock up to 20% off a property’s value because of the damage rodents cause and the health risks they present.
On average-price properties, that figure could equate to £53,000.
The company also notes that sellers are legally obliged to disclose infestations when marketing a property, and failure to do so can lead to legal disputes or cancelled sales.
Meanwhile, most standard home insurance policies do not cover damage caused by rodents, with insurers typically treating infestations as a maintenance issue rather than an unforeseen risk.
Some policies or add-ons – such as home emergency cover or specific buildings-cover provisions – may help with certain consequences of infestation (water damage from gnawed pipes, for example), but cover varies widely and homeowners are advised to check policy terms.
Greg Wilson, home insurance expert and CEO at Quotezone said: ‘Rats are far more than just a nuisance – these unwanted intruders are a serious threat to properties and household finances.
‘They pose significant health risks to humans and pets too, due to the various illnesses they carry which can be passed on through their droppings, urine, or even a bite.
‘It’s important to act at the first sign of rodent activity, whether the property is on the market or not. Early intervention can prevent costly repairs and ensure the home remains safe and insurable.
‘When homeowners take out home insurance, they agree the property will be well-maintained and cared for. Incidents that arise due to wear and tear will not likely be covered and leave owners vulnerable – making it crucial to do property checks now, before the darker evenings arrive, sealing any gaps and making sure food sources can’t be accessed.’
Estimates of the UK rat population vary widely; one commonly cited range is between about 10.5 million and 120 million, reflecting the difficulty of precise counting.
How to spot and prevent rat infestations
Early signs of infestation include droppings, greasy rub marks along skirting boards or entry points, gnawed packaging and unexplained holes.
Preventive steps recommended by pest experts include:
- Sealing gaps, cracks and holes around foundations, doors and windows with appropriate materials.
- Storing food in airtight containers and keeping kitchens and food storage areas clean.
- Removing garden debris and avoiding leaving rotting food in compost heaps.
- Eliminating standing water and fixing leaks.
- Using deterrents or, for persistent problems, engaging a licensed pest-control professional.
Pest-control professionals say proactive home maintenance is the most effective defence.
Buyers and sellers should ensure any past or present rodent issues are disclosed in property transactions, while homeowners concerned about the cost of removal should review their insurance policies to see whether any cover applies, and consider contacting a reputable pest-control firm for an inspection.
With experts predicting greater rodent activity this winter, households are being advised to act early to avoid structural damage, potential health problems and complications when selling a home.
