In our region, we see a unique mix of aging infrastructure and high-demand modern tech (like EV chargers). Here are the top electrical "red flags" we’re seeing across Surrey and West Sussex right now, and what you should do about them.

1. The Persistent "Tripping" Fuse Box

If your consumer unit (fuse box) trips every time you turn on the kettle or the shower, you aren’t alone. This is one of the most searched electrical issues in Reigate and Horsham.

The Cause: Often, it’s a faulty appliance or an overloaded circuit. However, in many older Surrey homes, the consumer unit simply isn't rated for modern electrical loads.

The Fix: A professional fault-finding diagnostic can identify if you need a simple circuit tweak or a full consumer unit upgrade to meet 2026 safety standards.

2. Flickering Lights in the Wind?

Residents in more rural parts of West Sussex and the Surrey Hills often report flickering lights.
The Cause: While this can be a loose bulb, it’s frequently caused by "voltage drop" or issues with the external overhead power lines common in our wooded areas.

The Fix: If it’s happening across multiple rooms, call a local electrician to check your main connections before it leads to a total power loss.

3. The Need for EICR Compliance

With a high density of rental properties in Reigate and Chichester, EICR (Electrical Installation Condition Report) searches are at an all-time high.

The Requirement: Landlords are legally required to have these every five years, but we are increasingly seeing savvy homebuyers in Redhill requesting them before closing a deal to avoid "hidden" rewiring costs.

4. EV Charger Integration

Surrey and West Sussex have some of the highest EV ownership rates in the UK. We frequently help homeowners who have tried to "plug and play" only to find their home’s internal wiring can't handle the sustained draw.

How much does an EICR cost in Surrey?

Cost varies depending on property size, but most domestic and commercial EICR inspections take between 2-4 hours. Please contact us for a fast quote.
