If you are renovating a Victorian property in Southbourne, updating a mid-century home in Charminster, or purchasing an older flat in Poole, you will likely need to assess the electrical infrastructure.
A full house rewire is one of the most significant structural and safety investments you can make in your property. But how much should it actually cost?
At SC Electric, we operate strictly on a "written-quote only" basis with zero hidden extras. To help you budget for your renovation, we have compiled this transparent guide to house rewire costs in the Bournemouth and Dorset area for 2026.
Average House Rewire Costs in Bournemouth
Every property is unique, but having a benchmark is crucial before you start inviting contractors for site surveys. The following estimates are based on fully compliant installations to the latest BS7671 (18th Edition, Amendment 4) standards, including a new Surge Protection Device (SPD) consumer unit.
- 1-2 Bedroom Flat: £2,500 – £3,500+ VAT(Average duration: 5-7 days)
- 3 Bedroom House: £4,000 – £5,500+ VAT(Average duration: 7-10 days)
- 4+ Bedroom House: £6,000++ VAT(Average duration: 10-14 days)
Note: These prices reflect standard white-plastic finishes. Upgrading to premium screwless metal faceplates, smart-home lighting, or complex outdoor power routing will increase material costs.
What Actually Dictates the Price?
Many homeowners are surprised by the variance in quotes they receive. If a quote seems exceptionally low, it is usually because vital safety upgrades have been omitted, or "making good" (repairing the plaster) is not factored in.
Here are the primary factors that influence your final quote:
1. Occupancy (Vacant vs. Lived-in)
This is the single biggest variable in the project costs. Rewiring is a highly invasive process. It involves lifting floorboards, chasing channels into brickwork, and dealing with significant amounts of dust. If the property is empty, our engineers can move quickly and efficiently from room to room. If the property is occupied, we must spend hours each day moving furniture, laying protective sheets, and restoring temporary power so you can live safely overnight. A vacant property will always result in a cheaper quote.
2. The Scope of the "First Fix"
The "First Fix" involves running the hidden cables. If you are adding more sockets to meet modern demands (e.g., home offices, wall-mounted TVs, kitchen islands), more chasing is required into the walls. Solid brick walls (common in older Bournemouth properties) take longer to chase than modern stud walls.
3. Making Good (Plastering)
Once the cables are embedded in your walls, those channels need to be filled. Some electricians leave the walls rough, requiring you to hire a separate plasterer. At SC Electric, our quotes clearly outline the scope of "making good" so you aren't left with an unexpected secondary bill.
Signs Your Bournemouth Property Needs a Rewire
Wiring degrades, and the electrical demands of a household in 2026 are vastly different from those in 1980. If your home exhibits any of the following, a rewire is likely necessary:
- Outdated Consumer Unit: If your fuse board has replaceable wire fuses or lacks RCD/RCBO protection.
- Old Cabling: The presence of black rubber, fabric, or lead-insulated cabling.
- Scarcity of Sockets: Relying heavily on extension leads because rooms only have one or two single sockets.
- Surface Degradation: Sockets mounted in the skirting boards or switches that are cracking and discolored.
- Constant Tripping: If running the kettle and the microwave simultaneously trips the power.
The SC Electric Standard
When you hire SC Electric for a full rewire, you are paying for technical precision and absolute safety.
We do not cut corners. Every rewire we complete includes an RCBO-populated consumer unit with full Surge Protection (SPD) as standard. Upon completion, we issue comprehensive NAPIT digital certification and register the work with local Building Control, ensuring your property is fully compliant for insurance and future sale purposes.
