Not every property needs a complete strip-out and full rewire. Where sections of your electrical installation are in good condition but other areas have deteriorated, a partial rewire targets only the circuits and cabling that need replacing. This approach delivers a safe, compliant installation at a lower cost and with less disruption than rewiring the entire house.
Partial rewires are common across Brighton’s older housing stock, particularly in properties that received some electrical updating in the 1980s or 1990s but still have original wiring in certain rooms or on specific circuits. An EICR often identifies exactly which sections fall below standard, giving you a clear picture of what needs replacing and what can safely remain.
We carry out partial rewires across Brighton, assessing every circuit individually and replacing only what genuinely needs attention. We give honest advice on whether a partial or full rewire is the right approach for your property, based on the condition of the installation rather than defaulting to the most expensive option.

A partial rewire suits properties where some of the wiring is in acceptable condition but other sections have deteriorated or no longer meet safety standards. Common scenarios include homes where the downstairs was rewired during a previous renovation but the upstairs still has original cabling. Or properties where the lighting circuits are sound but the socket circuits use outdated wiring without adequate earthing. If your EICR has classified certain circuits as C1 or C2 while others passed satisfactorily, a partial rewire addresses the failures without disturbing the circuits that don’t need attention. We assess every circuit on its own merits and recommend the most proportionate and cost-effective approach for your Brighton property.
If you’re renovating specific rooms — a kitchen, bathroom, or bedroom — it makes sense to rewire those areas at the same time while the walls are open and accessible. We replace all cabling, sockets, switches, and lighting within the rooms being renovated, connecting the new wiring to your existing consumer unit or upgrading the board if additional capacity or protection is needed. This approach is significantly cheaper than rewiring the same rooms as a standalone project because the access is already there and the plasterer is already booked. Planning your electrical work alongside a room renovation avoids paying twice for disruption and making good.
Sometimes the issue isn’t a whole section of the house but specific circuits that have deteriorated or are no longer fit for purpose. A lighting circuit with fabric-covered cable running through the ceiling void. A socket circuit without an earth conductor. A shower circuit on undersized cable. We replace individual circuits by running new cabling from the consumer unit to every outlet on that circuit, removing or abandoning the old wiring. Each replacement circuit is tested individually and certified on completion. Circuit replacement is a targeted, cost-effective way to address specific defects identified on an EICR without the scope and cost of a wider rewire.
One of the key challenges with a partial rewire is ensuring the new wiring integrates safely with the existing installation. Where new circuits connect to an older consumer unit, the board may need upgrading to provide adequate RCD protection for the new work. Where new and old circuits coexist, the earthing and bonding arrangements must be consistent and compliant across the whole installation. We test the entire system on completion, not just the circuits we’ve replaced, to confirm that everything works together safely. Our experience across Brighton’s mixed-age housing stock means we understand how to bring older installations up to standard without unnecessary scope creep.
A partial rewire requires careful judgement about what needs replacing and what can safely remain. Getting that balance right saves you money without compromising safety. We assess every circuit individually using proper testing rather than making assumptions, and we give you an honest recommendation on whether a partial or full rewire is the right approach for your specific property.
We are fully qualified, NICEIC registered, and experienced across the full range of Brighton’s housing stock. Every partial rewire is completed to current BS 7671 standards with full testing and certification. We explain our findings clearly, provide detailed quotes with no hidden costs, and only replace what genuinely needs replacing.
We carry out partial rewires throughout Brighton and the surrounding area, covering Hove, Kemptown, Hanover, Seven Dials, Preston Park, Fiveways, Patcham, Rottingdean, Saltdean, Woodingdean, Peacehaven, Lewes, and surrounding East Sussex areas.
Charge your electric vehicle at home with a professionally installed charging point. A dedicated 7kW home charger delivers a full overnight charge for most vehicles, saving you time and money compared to public charging. We install all major brands including Easee, Zappi, Ohme, and Pod Point, handling the full process from electrical assessment through to commissioning and certification. If you’re having a full rewire, adding an EV charger circuit at the same time is significantly cheaper than installing one separately later. Professional EV charger installation across Brighton.
Good lighting transforms how a room looks and feels, and a rewire is the ideal opportunity to upgrade your lighting throughout the property. We install recessed downlights, pendant lights, dimmer circuits, under-cabinet kitchen lighting, bathroom lighting to zone regulations, and outdoor lighting for security and ambiance. Planning your lighting scheme during the rewire means all wiring is in place before plastering, giving you a cleaner finish and more flexibility than retrofitting later. Whether you want a simple upgrade or a complete lighting redesign across your Brighton home, we handle the full installation.
A consumer unit upgrade is often carried out alongside a partial rewire to ensure the board provides adequate protection for both new and existing circuits. We replace outdated fuse boards with modern units fitted with MCBs and RCDs or individual RCBOs, providing circuit-level fault detection that your old board cannot offer. If your partial rewire adds circuits or changes the demands on the board, upgrading at the same time keeps costs down and ensures the whole installation is properly protected. Every upgrade includes full testing and an electrical installation certificate for your records.
