Electrical Wiring Cost in Karachi: Repair or Complete House Rewiring?
A faulty socket, a new AC connection and a complete house rewire are three different jobs. Before comparing prices, establish what needs repair, what needs adding and whether the existing installation can safely support the planned work.
Quick answer
Electrical wiring cost in Karachi depends on circuit scope, cable specification, labour, access and wall finishing. A useful quotation separates repairs, new points, circuit wiring, distribution board work and reinstatement. Full rewiring should follow an assessment of the installation.
Do you need a repair, an extra point or full rewiring?
Start with the problem you want to solve. A dead socket does not automatically mean the whole house needs rewiring. Equally, fitting a new socket does not prove that the cable supplying it is in good condition.
| Work type | What it covers | What needs checking |
|---|---|---|
| Local repair | An identified fault at a fitting, connection or limited section | The cause of the fault and condition of the affected circuit |
| Additional point | A new socket, light or other connection | Existing circuit capacity, protection and cable route |
| New or replacement circuit | Wiring for a defined load or an affected circuit | Load requirements, cable selection, earthing and board capacity |
| Complete house rewiring | A planned replacement of the agreed installation | Whole-property scope, retained components, access and finishing |
Explain the symptoms and planned appliances when requesting electrical services in Karachi. The recommended work should address those needs and the inspection findings.
What changes the electrical wiring cost?
Cable specification and route length
A quotation should identify the cable specification and quantity, rather than simply promise “good wire.” Selection depends on the intended load, installation method, route and protective devices. Floor area alone cannot establish the cable requirement.
Number and type of points
A light point and a connection for a high-load appliance should not be treated as interchangeable. Give the electrician a room-by-room list of sockets, lights, fans and appliance connections so the estimate reflects what you actually need.
Distribution board and earthing work
Ask whether the existing distribution board can accommodate the proposed work and whether any protection or earthing improvements are required. These items should be identified separately instead of appearing as unexplained extras later.
Access and property condition
An empty room with accessible routes is different from an occupied flat with fitted furniture, tiled walls and limited working hours. Moving belongings, protecting finishes and coordinating power interruptions can affect the job.
How should you compare per-point wiring rates?
Ask each contractor to define a “point.” One quotation may include cable, conduit, a box and labour. Another may cover installation labour only, with switches, sockets and the cable run charged separately.
- Which type of point does the rate cover?
- What cable specification and route length are included?
- Are conduit, boxes, switches and sockets included?
- Does the price include chasing and making good?
- Are circuit feeds, board work and testing separate?
A practical way to calculate the budget
Total the agreed point work, separate circuit work, board and earthing work, access work, finishing and testing. Check that materials included in a point rate are not charged a second time elsewhere.
For example, a room with four sockets, two lights and a fan has seven requested points. An AC connection should be listed separately with its assessed circuit requirements. That list is a starting scope, not confirmation that the existing supply can support every addition.
Concealed wiring: include the cost of restoring the walls
Concealed work may involve opening wall channels, installing conduit and boxes, then restoring the surface. Existing conduit may be reusable, but its route, capacity and condition need checking first.
Surface-mounted conduit or trunking may reduce wall opening where suitable, although it remains visible. Discuss the route and appearance before selecting an option.
Ask who handles plaster, tiles and paint afterwards. A patched area may still look different from the surrounding wall. If you want a consistent finish, include the relevant wall area in the painting scope rather than assuming small touch-ups will match.
When is complete house rewiring worth considering?
The age of a house is a reason to ask about its electrical history, not a diagnosis. Inspection and testing help establish whether the installation needs local repairs, selected circuit replacement or more extensive work.
A wider assessment is particularly useful when there are repeated faults, evidence of deterioration, undocumented alterations or major changes to the intended electrical load. Renovation is also an opportunity to plan point locations before walls are finished.
Ask for the findings behind a full-rewire recommendation. If partial replacement is proposed, the quotation should identify what remains and how the retained installation will be assessed.
Do not treat repeated tripping as a pricing issue alone
A breaker can trip for different reasons. Do not repeatedly reset it or replace it with a higher-rated device to stop the symptom. Burning smells, scorching, sparks or shocks require prompt professional attention. Avoid using the affected equipment and do not open the distribution board yourself.
What should a wiring quotation include?
Compare the written scope before comparing the final total. A cheaper quotation may exclude materials or finishing work that another contractor has already included.
| Item | Details to request |
|---|---|
| Points and circuits | Room-by-room quantities, locations and intended loads |
| Materials | Cable specification, quantities, accessories and agreed brands |
| Board and earthing | Proposed changes and items retained |
| Labour and access | Installation, chasing, removal and site protection |
| Finishing | Plaster, tiles, painting and debris removal responsibilities |
| Testing and handover | Completion checks, circuit labels and documentation provided |
| Commercial terms | Payment stages, exclusions, variation approval and warranty scope |
Labour-only work also needs a clear materials list. If you supply the materials, agree the specifications before purchase and confirm who handles shortages or unsuitable items.
Explore the Pronto PK service price estimator for available estimates. A complete rewiring budget still requires an assessment and a defined project scope.
What to send for an electrical wiring estimate
- Your Karachi locality, property type and approximate covered area.
- Whether you need a repair, additional points or a renovation estimate.
- A room-by-room list of required points and major appliances.
- Photos of the rooms and the closed distribution board, taken safely.
- Whether the property is occupied and when work can take place.
- Your preference for concealed or visible routes and any finishing requirements.
Photos help explain the job, but they cannot establish concealed cable condition or replace electrical testing. A site assessment may be needed before confirming the final work and price.
Frequently asked questions
Can house wiring cost be calculated from floor area alone?
Floor area can provide an initial reference, but it does not define the number of points, cable routes, appliance loads or condition of the existing installation. A firm quotation needs a more detailed scope.
Does an old house always need complete rewiring?
No. Age alone does not establish the required work. Inspection and testing help determine whether local repairs, selected circuit replacement or complete rewiring are appropriate.
Does a per-point rate include switches and cable?
It depends on the quotation. Ask for the included cable specification, route length, conduit, boxes, accessories and labour to be listed before comparing rates.
Can existing concealed conduit be reused?
It may be reusable if its route, condition and capacity suit the proposed work. This needs checking before assuming new cable can be installed without opening the walls.
Are plaster repairs and painting included in rewiring?
Only if the quotation includes them. Confirm who restores wall channels, replaces damaged finishes and repaints the affected areas before work begins.
