Rewiring
Safe, Professional Electrical Rewiring
If your property requires professional rewiring, Big Fish Electricians provides reliable electrical rewiring services for homes across Portsmouth and the surrounding areas. Rewiring is a vital upgrade for properties with ageing or unsafe electrical systems, helping to protect occupants while ensuring electrics meet modern standards and demands.
As experienced electricians Portsmouth homeowners rely on, we carry out electrical rewiring with care, planning, and full compliance with current UK wiring regulations. Whether you are renovating, experiencing electrical issues, or updating an older property, professional rewiring provides long-term safety and reliability.
When Is Rewiring Needed?
Many properties require house rewiring when existing wiring becomes outdated or unsafe. Warning signs can include frequent tripping, discoloured sockets, brittle wiring, or electrics that no longer support modern appliances. In older properties, particularly those that have not been updated for decades, rewiring an old house is often recommended to bring the system up to current standards.
Arranging an assessment with a qualified electrician in Portsmouth allows you to understand the condition of your wiring and whether full or partial rewiring is the safest option.

Electrical Rewiring for Homes
Electrical rewiring involves replacing old wiring, upgrading circuits, and improving overall system safety. This work is commonly carried out during renovations, extensions, or when preparing a property for sale or rental. We plan all rewiring work carefully to minimise disruption and ensure the finished installation is safe, tidy, and reliable.
As a trusted local electrician, we explain the process clearly before work begins, including timescales and what to expect during the project. This helps homeowners feel informed and confident throughout the rewiring process.

Older properties often present unique challenges when it comes to electrics. Rewiring an old house requires experience, careful planning, and respect for the structure of the building. We regularly work in older homes across Portsmouth, adapting our approach to suit traditional layouts while ensuring modern safety standards are met.
