Estimate the likely cost of UK domestic electrical projects, including house rewiring, EV charger installation and consumer unit replacement. CostIntel calculators are built for early project planning before you speak with a qualified electrician.
These estimates are planning ranges, not fixed quotes. Electrical work needs a property-specific inspection before the final scope, safety requirements and price can be confirmed.
Start with the calculator that best matches the work you are pricing. Some electrical projects overlap, so the right starting point depends on whether your main concern is wiring, EV charging or the consumer unit.
Estimate the cost of a full house rewire, partial rewire, room-by-room upgrade or rewiring work in an occupied home.
Best for older wiring, renovation planning, access disruption and making-good cost allowances.
Calculate rewiring costEstimate home EV charger installation costs based on charger type, parking setup, cable run, consumer unit location and access.
Best for driveway installs, longer cable runs, shared-parking complexity and capacity-dependent installs.
Calculate EV charger installation costEstimate the cost of replacing or upgrading a consumer unit, including fuse box replacement, testing and possible remedial work.
Best for dated fuse boxes, circuit-count uncertainty, upgrade planning and wider electrical safety projects.
Calculate consumer unit costThe best calculator depends on the main project scope. If the electrician later identifies related work, you can compare more than one estimate to understand the wider planning range.
| Project situation | Best starting point | Why it matters |
|---|---|---|
| You are replacing old wiring across the home | Rewiring Cost Calculator | Rewiring cost depends on property size, access, occupancy, finish level and how much making good is needed. |
| You need a home EV charger | EV Charger Installation Cost Calculator | Charger installation cost depends on parking, cable run, consumer unit distance, electrical capacity and region. |
| You are replacing an old fuse box | Consumer Unit Cost Calculator | Consumer unit replacement cost depends on circuit count, access, testing and whether remedial work is likely. |
| You are planning solar, battery or heat pump upgrades | Electrical hub plus relevant energy calculators | Wider energy upgrades can affect capacity, consumer unit planning and cable routes. |
| You are unsure what work is needed | Start with this Electrical Cost hub | A qualified electrician may need to inspect the property before the scope is clear. |
Domestic electrical costs are shaped by more than the main item being installed. Labour time, property access, existing wiring condition, testing requirements and regional pricing can all change the estimate.
Labour varies by region, project complexity, access, inspection time and the amount of work needed to complete the job safely.
Larger homes, multiple floors, loft spaces, extensions and older layouts can increase wiring routes, access time and disruption.
Older wiring, dated consumer units, unknown circuit condition and previous alterations can widen the cost range before inspection.
Occupied homes, finished rooms, awkward cable routes, parking limits and restricted working space can increase labour and making-good allowances.
Electrical projects often involve inspection, testing and paperwork related to the work being completed. The exact scope depends on the property and electrician.
London and higher-cost regions may sit above typical UK ranges, while some northern or lower-cost regions may price below the national midpoint.
These broad ranges help you understand the likely order of cost before using a calculator. The final price can change after an electrician checks the property, access, wiring condition and project scope.
| Electrical project | Typical planning range | Best use |
|---|---|---|
| Partial rewiring work | £1,000–£4,500+ | Room-by-room upgrades or limited wiring replacement |
| Full house rewire | £4,000–£12,000+ | Whole-home wiring replacement, depending on property size and disruption |
| Home EV charger installation | £800–£2,000+ | Standard to more complex home charger installs |
| Consumer unit replacement | £700–£2,000+ | Fuse box replacement, testing and possible remedial work |
| Electrical upgrade linked to wider work | Varies widely | Renovations, EV charging, solar, battery or heat pump planning |
Use the calculator pages for a more specific planning range. A fixed quote needs a property inspection by a qualified electrician.
Rewiring, consumer unit work and EV charger installation are separate project types, but one can affect another. The relationship matters when planning budget and timing.
A wider rewire may include consumer unit work, testing or related upgrades. If your fuse box is old, compare your rewire estimate with the Consumer Unit Cost Calculator.
Some EV charger projects are straightforward. Others depend on consumer unit condition, cable routes, available capacity, meter location and parking setup.
If you are planning EV charging alongside solar or storage, compare the electrical estimate with the Solar Panel Cost Calculator and Solar Battery Cost Calculator.
A heat pump can form part of a wider electrification plan. Use the Heat Pump Cost Calculator when comparing heating upgrades with electrical capacity planning.
Electrical quotes vary by scope, electrician, property condition and the checks needed before work starts. Use this table to understand what may sit inside or outside a typical planning estimate.
| May be included | May be excluded |
|---|---|
| Electrician labour for the agreed scope | Major building work or structural alterations |
| Standard materials for the selected project | Decorative making good beyond the agreed scope |
| Testing linked to the electrical work | Specialist remedial work found after inspection |
| Consumer unit work where included in the quote | Full rewiring if only a consumer unit is being priced |
| Basic waste removal | Asbestos, hidden damage or third-party upgrades |
| Certification or paperwork where relevant to the project | Network operator work or supply upgrades where required |
An online estimate can help you plan, but it cannot confirm the final electrical scope. A qualified electrician needs to check the property before giving a fixed quote.
Older or altered wiring may need inspection before the electrician can confirm whether partial or full rewiring is required.
A dated fuse box, limited circuit information or unclear labelling can affect the final scope and cost range.
Home charger installation may need checks around available capacity, consumer unit location, cable route and parking setup.
Rewiring in an occupied home can involve more planning, phasing, protection and disruption management.
Lofts, finished rooms, cupboards, flats, parking issues and long cable routes can change labour time.
Solar, battery storage, EV charging and heat pumps can create wider electrical planning questions that need property-specific checks.
CostIntel estimates are planning ranges. A qualified electrician needs to inspect the property before confirming scope, safety requirements and a fixed quote.
CostIntel electrical estimates are based on the main project type, property size, access complexity, existing electrical condition, labour intensity, testing-related scope, regional labour variation and contingency.
The calculators are designed for early planning. They do not replace an electrician’s inspection and they do not provide DIY electrical instructions or legal compliance advice.
