Home Rewires in Derby
Replace outdated, unsafe wiring with a fully certified electrical rewire, planned and delivered by qualified electricians with clear communication at every stage.
Home Rewires You Can Rely On in Derby
A rewire is one of the most significant electrical investments a home can need, and it is rarely something to rush. Older wiring, especially the rubber and lead-sheathed cables common in mid-20th century Derby properties, degrades over time and offers little of the protection expected of a modern installation. We plan every rewire around how you actually live in the property, replacing the fixed wiring with a safe, certified installation while keeping disruption and mess to a minimum.
“Give a Shit & Do The Right Thing” — our standard for every single customer emergency.

What a Home Rewire Covers
A rewire is more than pulling new cable through the walls. Every element of the fixed installation is renewed and brought up to current standards, with certification issued on completion.
Fixed Wiring Replacement
All existing cables within the walls, ceilings and floors are replaced with current-specification PVC insulated conductors sized for modern loads.
Consumer Unit Upgrade
A new consumer unit with RCBO protection and a surge protection device is installed to safely distribute the rewired circuits.
Sockets, Switches & Accessories
New socket outlets, light switches, and accessories are fitted throughout, finished neatly to suit the decoration that follows.
Lighting Circuits & Fittings
Lighting circuits are renewed and rewired for modern low-energy fittings, with provision for any additional lights you want added.
Earthing & Bonding
Main earthing and gas and water bonding are upgraded to current standards so the whole installation is properly protected.
Testing & Certification
Every circuit is fully tested, the work is notified to building control, and you receive your electrical installation certificate.
Full Rewire, Partial Rewire, or Rewire During Renovation
Not every property needs a full rewire. We assess your installation honestly and recommend the approach that fits the condition of your wiring and your plans for the home.
Full Rewire
Properties with ageing or unsafe wiring throughout
Every fixed cable in the property is replaced and a new consumer unit installed. This is the right choice when the existing wiring is old, damaged, or no longer meets current standards, or during a major refurbishment when walls and floors are already exposed.
Partial Rewire
Targeted upgrades where most wiring is sound
Specific circuits or rooms are renewed while sound existing wiring is retained. This suits properties where only part of the installation has failed an inspection or where an extension or conversion needs new circuits added.
Rewire During Renovation
Properties being refurbished or extended
Carrying out a rewire alongside building work keeps costs and disruption down because chases and access are already open. We coordinate with your builder to sequence the electrical work at the right stage.
We find the right solution for your property, not just the quickest fix. Our office team will talk you through the options and arrange a survey before any work begins.
