If you live in Boughton near the River Dee, youβre in one of the areas around Chester where rat activity tends to be higher. With the river close by, older drainage systems, and a mix of period properties, it creates the perfect environment for rodents to thrive.
One issue many homeowners donβt expect is rats getting into the loft and chewing through electrical cables. Itβs something we come across more often than youβd think.
I was recently called to a house in Boughton where the homeowner had lost power to part of the upstairs. At first, they thought it was just a faulty circuit. But when the electrician checked the loft, several cables had been chewed through. The cause? Rats had been nesting in the insulation and using the wiring as a chewing source
π§ Why Rats Chew Cables
Rats donβt chew cables for food β they do it because their teeth never stop growing. To keep them worn down, they constantly gnaw on materials around them.
Unfortunately, loft spaces provide plenty of targets:
- Plastic cable insulation is easy to chew
- Warm loft environments attract nesting
- Insulation materials provide shelter
- Quiet, undisturbed spaces allow activity to go unnoticed
In areas like Boughton, where properties are close to the river, and older drainage systems are common, rats often gain access via underground pipework and then move upwards into the property.
π Signs Rats May Be in Your Loft
Before you even see a rat, there are usually signs:
- Scratching or movement noises at night
- Electrical issues like flickering lights or dead circuits
- Droppings in loft insulation
- Chewed wood, pipes, or cables
- A strong, musky smell in the loft space
If cables are being damaged, itβs not just a nuisance β itβs a serious fire risk.
π οΈ How Rats Get In (And How We Stop Them)
In many cases, rats enter properties through damaged drainage systems. Cracked pipes or old clay joints allow them into the system, and from there they can travel into cavities and loft spaces.
A CCTV Drain Survey in Chester can identify entry points in the pipework. Once located, targeted Drain Repairs Chester can seal the system.
We also often install rodent-prevention devices to stop them from travelling back through the drains.

π Luke’s Expert Advice
If you hear scratching in the loft or notice electrical problems at the same time, donβt ignore it. Rats chewing cables can quickly become dangerous. The sooner you trace how theyβre getting in, the easier it is to stop the problem properly.
Installing a Ratgate is one of the most effective ways to prevent rats from entering your property through the drains, but it needs to be done properly to be effective in the long term. The first step is always to identify the right location in the pipework. Thatβs why we normally start with a quick CCTV check, so youβre not just guessing where to fit it.
The ratgate itself is fitted inside the pipe, usually on the line leading out of the property. It acts as a one-way valve, letting waste flow out while stopping anything from coming back in. The key is making sure itβs installed on a clean, free-flowing section of pipe. If itβs fitted in areas with debris or standing water, it wonβt perform properly.
Once itβs in, itβs a fit-and-forget solution. Just keep your drains maintained, and it will quietly protect your home in the background.
