Electrical Help & Advice — Liverpool, Birkenhead & the Wirral
Practical electrical advice from Dan, a NICEIC registered electrician with over 30 years of experience.
Electrical faults can be confusing. A tripping RCD does not necessarily mean you need a new consumer unit, and a damaged switch may not be the only problem with an installation.
I provide electrical fault finding, repairs and installations across Liverpool, Birkenhead and the Wirral. These guides explain common electrical problems, what may cause them and how to make informed decisions about repairs and improvements.
The advice is based on professional electrical experience, including documented examples of actual jobs. It is intended to help you understand electrical issues, not to encourage unsafe DIY electrical work.
Common Electrical Questions
Why does my RCD keep tripping?
An RCD detects an imbalance in electrical current and disconnects the supply when its operating conditions are met. Repeated tripping can result from a faulty appliance, moisture, damaged wiring or another electrical problem.
The RCD itself may be working correctly. The important question is what causes it to operate. Avoid repeatedly resetting a device that continues to trip.
Read why your RCD keeps tripping.
Why are my lights flickering?
A failing lamp, an unsuitable dimmer, a loose connection or an electrical supply problem may cause flickering lights. The cause matters, particularly if several lights flicker together or the problem is accompanied by unusual sounds, heat or burning smells.
Persistent flickering should be investigated rather than ignored.
Learn about electrical fault finding.
Is a buzzing fusebox dangerous?
Unusual buzzing or crackling, particularly when accompanied by a burning smell or visible heat damage, can indicate a dangerous electrical condition.
Do not remove the consumer unit cover or attempt to investigate live connections yourself. Arrange urgent professional attention.
On one job in Huyton, I found overheated neutral-bar connections and damaged wiring inside a consumer unit. The repair is documented with original photographs.
See the Huyton fusebox repair.
Does an old fusebox always need replacing?
No. Age alone does not establish whether a consumer unit must be replaced. Its condition, protective arrangements, suitability for the installation and relevant inspection and test findings all matter.
Sometimes a repair or limited alteration is appropriate. In other circumstances, a replacement is the sensible option.

Real Electrical Faults — My Work
These examples show why professional electrical fault finding is more than replacing a component that appears to be damaged.
Buzzing Fusebox in Huyton — Overheated Neutral Connections
During an October 2026 weekend call-out in Huyton, I investigated a consumer unit making an unusual buzzing noise and producing a burning smell.
The investigation identified an overheated neutral bar and damaged wiring. I isolated affected circuits while awaiting replacement parts, then returned to complete the repair and relevant checks.
The case study includes five original photographs and explains why a complete consumer unit replacement was not automatically necessary.
Read the Huyton fusebox case study.
Electric Shower Fault — Why Replacing the Switch Wasn't Enough
An electric shower circuit showed visible overheating at its switching equipment. Repairing the damaged connection addressed the first problem, but further investigation showed that the shower itself was causing the RCD to operate.
The case demonstrates why diagnosing the complete problem matters more than simply replacing the most visibly damaged component.
