House Rewiring in Liverpool: The Complete 2025 Guide for Homeowners

A house rewire is the complete replacement of all the electrical wiring, circuits, sockets, switches and lighting points in a property. It is one of the most significant electrical jobs a homeowner can undertake, and it is essential for both safety and functionality.

If your home was built before 1980 and has never been rewired, the chances are the wiring is now out of date, potentially dangerous and incapable of handling the electrical load of modern appliances. Old rubber or fabric-sheathed cables, outdated fuse boards and insufficient earth bonding are all serious risks that only a full rewire can resolve.

Common signs your home needs a rewire include: frequent tripping of fuses or RCDs, flickering lights, discoloured or warm socket faces, a burning smell from outlets, and visible rubber or fabric insulation on cables. If you experience any of these symptoms, contact a NAPIT approved electrician in Liverpool immediately.

A full house rewire replaces every cable, socket, switch, light fitting and the consumer unit. This is necessary when the existing wiring is old, damaged or no longer compliant with current regulations. A full rewire is also required for major renovations, extensions and new builds.

A partial rewire targets specific circuits or areas of the property. For example, you might rewire the kitchen and bathroom during a renovation while leaving the bedroom circuits untouched. Partial rewires are cheaper and faster, but they require careful integration with the existing wiring and a full assessment by a qualified electrician.

At Conaty&Co., we always carry out a thorough Electrical Installation Condition Report (EICR) before recommending any rewire. This inspection reveals the true state of your wiring, identifies hidden faults, and determines whether a full or partial rewire is the most cost-effective and safe solution.

Rewiring costs in Liverpool vary depending on the size of the property, the complexity of the installation, the number of circuits required and the quality of the fixtures you choose. As a guide, a typical 3-bedroom terraced house in Liverpool costs between £3,500 and £5,500 for a full rewire including a new consumer unit, sockets, switches and light fittings.

Larger properties and those with additional circuits for EV chargers, underfloor heating, outdoor lighting and smart home systems will cost more. Listed buildings and properties with restricted access also increase labour costs due to the additional care and time required.

We provide free, no-obligation quotes for every rewire. Our estimates are fully itemised so you know exactly what you are paying for — no hidden costs, no surprises. We also offer staged payment plans for larger projects, with payment due only at agreed milestones.

A typical 3-bedroom house rewire takes between 2 and 5 days to complete, depending on the property size, access, and the extent of the work. Our experienced team can complete some standard 3-bedroom properties in as little as 2 days by working efficiently and in parallel.

Before work begins, we carry out a detailed survey to identify the best cable routes, avoid structural elements, and plan the most efficient sequence of work. During the rewire, we protect your floors, furniture and belongings, and we make good any plasterwork disturbed by cable chasing once the wiring is complete.

We understand that living in a property during a rewire is disruptive. Where possible, we work room by room so you always have some areas of the house fully functional. For complete rewires, we recommend planning alternative accommodation for the first 1-2 days when power is temporarily disconnected.

All house rewires in England must comply with Part P of the Building Regulations, which covers electrical safety in dwellings. This means the work must be designed, installed, inspected and tested by a competent person — specifically a NAPIT or NICEIC registered electrician.

At Conaty&Co., every rewire is carried out by NAPIT registered electricians to BS 7671 18th Edition wiring standards. On completion, you receive an Electrical Installation Certificate (EIC) confirming that the work meets all regulatory requirements. This certificate is essential for insurance, property resale, mortgage applications and landlord compliance.

We also notify your local building control automatically, so you do not need to handle any paperwork yourself. Our job is not finished until your installation is fully certified, tested and compliant.
