How Much Does It Cost to Rewire a House in Brighton? 2026 Price Guide

If your Brighton home has aging electrics, rewiring may be on your mind. Perhaps an EICR has flagged concerns, you are experiencing electrical problems, or you are planning renovations and wondering whether to address the wiring at the same time. Whatever your situation, understanding realistic rewiring costs helps you budget appropriately and make informed decisions.

As NICEIC registered electricians who have rewired properties across Brighton and Hove for years, we understand that cost is often the first question homeowners ask. This guide provides transparent pricing for house rewiring in Brighton in 2026, explains what affects costs, and helps you understand what your investment includes.

House Rewiring Costs at a Glance

Home rewiring costs in Brighton depend primarily on property size, type, and complexity. For Brighton properties in 2026, the following prices represent typical ranges for complete rewiring including a new consumer unit, all cables, sockets, switches, light fittings, testing, and certification.

A one-bedroom flat typically costs £2,000 to £3,000 for a full rewire. Two-bedroom flats and smaller terraced houses range from £2,500 to £4,000. Three-bedroom terraced houses or semi-detached properties, the most common type we rewire in Brighton, generally fall between £3,500 and £5,500. Larger four-bedroom houses cost £5,000 to £7,500 or more depending on size and complexity.

These figures cover the electrical work only. They do not include making good plasterwork or redecoration, which many homeowners arrange separately or handle themselves. If you want plastering included, add approximately £1,000 to £2,000 depending on the extent of chasing and repair required.

What Affects Rewiring Costs?

The price ranges above reflect the variation between straightforward and complex rewiring projects. Several factors influence where your property falls within these ranges.

Property Size and Layout

Larger properties need more cable, more sockets and switches, and more labour hours to complete. However, layout matters as much as floor area. A compact three-storey Victorian terrace in Hanover requires more vertical cable runs and ladder work than a sprawling single-storey bungalow of similar floor area. Complex layouts with multiple small rooms cost more than open-plan spaces with fewer circuits.

Construction Type

How your property is built significantly affects rewiring costs. Timber-floored properties with accessible voids allow cables to run beneath floors with minimal disruption. Solid concrete floors, common in flats and some modern houses, require surface-mounted conduit or extensive chasing, adding cost and complexity. Solid walls need chasing for vertical cable runs, while stud partition walls allow cables to pass through more easily.

Brighton’s housing stock includes everything from Regency townhouses with multiple floors and solid walls to Victorian terraces with suspended timber floors to 1960s blocks with concrete construction throughout. Each presents different challenges and costs.

Accessibility

Properties with good access to floor voids, loft spaces, and wall cavities rewire more quickly and cheaply than those where every cable run requires chasing or surface mounting. Basements and cellars can simplify ground floor wiring but may need their own circuits. Loft conversions that have boarded over all access points complicate first floor wiring significantly.

Number of Circuits and Accessories

Modern expectations for socket numbers far exceed what older installations provided. A rewire offers the opportunity to install sockets where you actually need them rather than relying on extension leads. More sockets, additional lighting circuits, dedicated circuits for high-power appliances, and provision for future additions like EV chargers all affect cost. We discuss your requirements during assessment to ensure the rewired installation meets your needs.

Existing Installation Condition

Properties where old cables can be drawn out and new cables pulled through existing routes rewire more easily than those where old wiring is embedded or inaccessible. Previous partial upgrades using different routes may complicate matters. The condition of existing back boxes, earthing arrangements, and bonding also affects the extent of work required.

Rewiring Costs by Property Type in Brighton

Brighton’s diverse housing stock means rewiring costs vary significantly between property types. Here is what to expect for common Brighton properties.

Victorian and Edwardian Terraces

Brighton has thousands of Victorian and Edwardian terraced houses in areas like Hanover, Seven Dials, Preston Park, and Fiveways. These typically two or three-storey properties with suspended timber floors and solid external walls present a familiar rewiring scenario. A three-bedroom Victorian terrace typically costs £4,000 to £5,500 to rewire. The suspended floors aid cable routing, though multiple storeys and solid walls require careful planning for vertical runs.

Regency and Georgian Townhouses

The grand Regency properties around Kemp Town, Brunswick, and the seafront present unique challenges. Multiple floors, high ceilings, ornate cornicing that should not be disturbed, and often listed building constraints all affect approach and cost. Rewiring a four or five-storey Regency townhouse may cost £7,000 to £12,000 or more, particularly if sympathetic approaches are needed to protect period features.

Purpose-Built Flats

Brighton has many purpose-built flat developments from various eras. 1930s mansion blocks often have generous room sizes with solid floors and walls. Post-war blocks frequently feature concrete construction throughout. Modern flats may have easier access but smaller footprints. A typical two-bedroom flat costs £2,500 to £4,000 to rewire, with construction type significantly affecting the final price.

Converted Flats

Many Brighton houses have been converted into flats, particularly larger Victorian and Edwardian properties. Rewiring a converted flat can be complicated by shared risers, uncertainty about which cables belong to which flat, and restrictions on work affecting common areas. Costs typically range from £2,500 to £4,500 depending on size and complexity.

Semi-Detached and Detached Houses

Suburban areas like Patcham, Westdene, Hollingbury, and Woodingdean have more semi-detached and detached houses, often from the inter-war or post-war periods. These properties typically have simpler layouts and better access than multi-storey terraces. A three-bedroom semi usually costs £3,500 to £5,000 to rewire, while larger detached houses range from £5,000 to £7,500.

What Does Rewiring Include?

Understanding what your rewiring quote covers helps you compare prices fairly and avoid surprises.

A complete rewire includes a new consumer unit with modern RCD protection and MCBs, all new circuit cables throughout the property, new sockets in agreed positions typically including doubles in all habitable rooms, new light switches and ceiling roses or pendants, new connections to fixed appliances like cookers and immersion heaters, comprehensive testing of all circuits, an Electrical Installation Certificate, and Building Control notification.

Items typically excluded unless specifically quoted include making good plasterwork and decoration, moving or upgrading the meter position, external supplies to outbuildings, and specialist lighting or smart home systems. We clearly specify what is included in our quotations so you know exactly what to expect.

Full Rewire vs Partial Rewire

Not every property needs complete rewiring. If some circuits have been updated more recently while others remain original, a partial rewire addressing only the deficient circuits may be appropriate. This costs less than a full rewire but provides less comprehensive improvement.

Partial rewiring makes sense when identifiable circuits need replacement while others remain serviceable, when budget constraints prevent complete rewiring but safety issues need addressing, or when the property will undergo phased renovation over time. We assess your entire installation and advise honestly whether full or partial rewiring is appropriate for your situation.

How Long Does Rewiring Take?

First fix electrical work, installing all cables and back boxes, typically takes one to two weeks depending on property size. You can usually remain in the property during this phase, though there will be disruption and dust. Second fix, installing sockets, switches, and light fittings after plastering and decoration, takes two to four days.

The gap between first and second fix depends on your plasterer and decorator rather than electrical requirements. We coordinate with other trades where possible to minimise your overall project duration.
