A full rewire of a three to four bedroom Dubai villa typically costs AED 90,000 to 180,000 including a new distribution board, all circuits, lighting, sockets and certification. A five to six bedroom villa runs AED 160,000 to 300,000. Doing it during a renovation, with ceilings and walls already open, costs a fraction of retro-fitting it afterwards.
How to tell if you need one
Age is the main indicator. Villas over fifteen years old frequently have distribution boards without adequate RCD protection, circuits undersized for modern kitchen and AC loads, and cabling near the end of its service life.
Nuisance tripping, warm socket faceplates, discoloured outlets or an absence of RCDs all point the same way. A survey settles it in about an hour.
Why timing changes the cost so much
A rewire needs access to every circuit route. In a finished villa that means chasing walls, lifting ceilings, then making good and redecorating throughout — which can easily double the cost.
Done as part of a renovation where surfaces are already open, the same work is dramatically cheaper. If you are renovating anyway and the property is over fifteen years old, this is the item to bring forward rather than defer.
What about DEWA
Alterations to the incoming supply, load increases and new connections require DEWA involvement and an appropriately registered contractor. Internal circuit alterations within the existing supply generally do not, but still require proper testing and certification.
When a rewire is actually needed
Age is the first indicator. Wiring installed fifteen or twenty years ago in this climate, feeding a modern appliance load it was never designed for, is working harder than it was specified to. The second indicator is the consumer unit — boards without adequate protection, or without the capacity for what is now plugged into the house.
The third is simpler: if the ceilings are coming down anyway for any other reason, the marginal cost of rewiring at that moment is a fraction of doing it as its own project later.
What a rewire includes
New circuits and cabling throughout, a new consumer unit with current protection, new accessories, and the earthing and bonding that goes with them. Then the builder's work — chasing walls, lifting and reinstating ceilings, and making good afterwards.
That last part is routinely underestimated. The electrical materials are a modest share of a rewire; the access, the making good and the redecoration are most of it.
Doing it with the renovation
This is the clearest case in the whole of renovation for doing two things at once. A rewire requires access to every ceiling and most walls. A renovation opens them anyway.
Done together, you pay for the access once. Done separately, you pay to open and make good a house you have just finished decorating, which is why rewiring after a renovation is close to the most expensive sequence available.
How we arrive at a figure
We do not price from a floor area and a rate. We measure the work and produce a bill of quantities — every element listed, quantified and rated — so that what you are agreeing to is legible rather than implied.
That is also what makes two quotations comparable. A single lump sum tells you nothing about what has been included; a measured breakdown tells you exactly where the difference between two prices sits. For an indicative range before any of that, the cost calculator takes about a minute.
| Scope | What it includes | Indicative range |
|---|---|---|
| Full rewire, 3–4 bed | New board, all circuits, lighting, sockets, certification | AED 90k – 180k |
| Full rewire, 5–6 bed | As above at larger scale with additional distribution | AED 160k – 300k |
| Plumbing replacement | Hot and cold supply throughout, water heaters, isolation | AED 45k – 130k |
| Drainage alterations | New soil and waste runs, fall corrections, venting | AED 25k – 90k |
A rewire is rarely the whole job. The renovation cost calculator will show you an indicative all-in range once the rest of the work is included.
Related Questions
How do I know if my villa needs rewiring?
Age is the main indicator. Villas over fifteen years old frequently have distribution boards without adequate RCD protection, circuits undersized for modern loads, and cabling near end of life.
Nuisance tripping, warm socket faceplates, discoloured outlets or an absence of RCDs all point the same way. A survey settles it in about an hour.
Can I rewire room by room?
Technically yes, but rarely economic. A rewire needs access to every circuit route back to the board, so doing it piecemeal means repeatedly opening and making good the same walls.
If the property genuinely needs rewiring, it is substantially cheaper done once, properly, while surfaces are already open.
What does a rewire actually cost?
Less in materials than people assume and more in access. Cable and accessories are a modest share; chasing walls, lifting and reinstating ceilings and making good afterwards is most of the figure. That is also why doing it during a renovation, when those surfaces are open anyway, costs a fraction of doing it alone.
Can I rewire without taking the ceilings down?
Partially, in some properties, but a full rewire needs access to the routes. Partial approaches tend to leave a mix of new and old circuits, which creates its own problems and means you have paid for most of the disruption without getting the whole benefit.
Should I upgrade the consumer unit separately?
It is possible and sometimes sensible as an interim safety measure, but a new board on old circuits does not fix the circuits. If the wiring is at end of life, replacing the board alone addresses the protection without addressing the cause.
Does a rewire need a permit?
Electrical work does not usually change structure, drainage or the approved layout, so a Dubai Municipality modification permit is often not required. The community NOC is still needed for access and contractor registration, and the work has to be carried out and certified by competent people.
How long does a villa rewire take?
Two to four weeks for the electrical work itself in most villas, plus the making good and redecoration afterwards, which takes longer than the wiring. Within a full renovation it disappears into the programme; as a standalone project it is a disruptive month.
Will a rewire improve my electricity bill?
Marginally and indirectly. Rewiring is about safety, capacity and reliability rather than consumption. What does reduce the bill is what often accompanies it — LED lighting throughout, better controls, and air conditioning that is correctly sized rather than running constantly to compensate for poor distribution.
Can I add circuits without a full rewire?
Often, yes, if the board has capacity and the existing installation is sound. Adding a circuit for a new kitchen or an EV charger is a contained job. It becomes a false economy where the existing wiring is at end of life, because you are extending something that needs replacing.
Does a rewire mean replastering the whole house?
Not entirely, but it means chasing walls where cables run and lifting ceilings where they cross. The making good is substantial and it is the larger part of the cost. This is exactly why doing it during a renovation, when walls and ceilings are open anyway, is so much cheaper than doing it alone.
What certification should I get?
A completion certificate and test results for the installation from whoever carries out the work. Keep them — they matter at resale, they matter to an insurer, and they are the evidence that the work was done and tested rather than merely invoiced.
Can I live in the house during a rewire?
Not comfortably. Power is off in sections for extended periods, ceilings are open, and the dust from chasing walls reaches everywhere. For a whole-house rewire most people move out, which is another argument for doing it inside a renovation when the property is empty anyway rather than as a standalone project later.
