Should You Rewire a House Before Buying It?

If you are buying a house in Ghana from the diaspora — London, Toronto, New York, Amsterdam — you are making one of the largest decisions of your life on the basis of photographs, a video walkthrough, and the word of someone you trust. Most of the house can be judged that way. The electrical wiring cannot. It is hidden in the walls, it does not show up in photos, and the seller has no reason to mention it. Yet it is exactly where an old Ghanaian house most often hides a serious, expensive problem. Here is how to think about it before you commit.

Why Wiring Is the Blind Spot in a Diaspora Purchase

You can see a cracked wall, a leaking roof, or a tired kitchen in a video call. You cannot see undersized cable, missing earthing, decades-old joints baking inside a wall, or a consumer unit that was never sized for the AC units and water heaters a modern family runs. A house can look freshly painted and beautiful and still be carrying wiring that is one hot day away from a fault — or a fire.

This is especially true of older Accra and Kumasi homes. A house wired thirty years ago was wired for a thirty-year-old electrical load: a few lights, a fridge, a TV. Add air-conditioning, electric water heaters, a borehole pump, and a houseful of chargers, and that original wiring is being asked to carry far more than it was designed for.

The Question to Ask Before You Sign

Not “should I rewire it?” — you cannot answer that yet. The right first question is: “What condition is the wiring actually in?”

That is answered by an electrical inspection, not a guess. Before you transfer money, you want a licensed electrician to physically test the installation and tell you, in writing, what is sound and what is not. It is the cheapest insurance you will ever buy on a property purchase — a fraction of the price, against the cost of discovering the truth after you own it.

What an Inspection Tells You That a Video Cannot

A proper inspection checks the things that decide whether the house is safe:

The Consumer Unit and Circuit Protection

Is the board modern and correctly protected, or an ageing fuse box with no proper circuit protection for today’s loads?

Earthing and Bonding

The single most important safety feature in the house — and the one most often missing or degraded in older properties. Without proper earthing, a fault that should trip a breaker instead makes metal live.

Cable Condition and Sizing

Whether the cable is the right size for the load, and whether decades of heat have left insulation brittle and cracking inside the walls.

Sockets, Joints and Moisture Damage

Burnt sockets, loose connections, and the rainwater ingress that is so common in Ghana’s climate.

So — Rewire, or Not?

The honest answer is: it depends entirely on what the inspection finds, and any electrician who tells you otherwise before testing is guessing.

The Timing Argument: Before You Move In

If a rewire is needed, doing it before you move in or before tenants arrive is far less disruptive. A rewire in an empty house is straightforward. A rewire in an occupied house means lifting furniture, chasing walls around people’s lives, and managing the dust and downtime. If you are buying anyway, the inspection result lets you plan the work into the purchase rather than living through it later.

What It Costs — Honestly

An inspection is priced on survey — it depends on the size of the property and how much is accessible. A rewire, if needed, is also priced on survey, because a three-bedroom bungalow and a four-storey house are not the same job, and an honest electrician will not pretend they are. What we will always give you is a clear written finding and a clear price before any work, never a number invented over the phone. If the work needs certifying, the Energy-Commission compliance certificate carries a statutory fee of GH₵300.

For Diaspora Buyers Specifically

You do not have to be in Accra to get this done. Electricals Ghana attends the property, inspects it, documents what we find with photographs, and reports back to you wherever you are — the same way we already act for diaspora landlords on tenanted properties across Greater Accra. You make the buy/negotiate/rewire decision with facts in hand, not with hope.

The Bottom Line

Do not decide whether to rewire from across an ocean. Decide whether to inspect — that part is almost always yes — and let the inspection tell you the rest. It turns the one part of the house you cannot see into the one part you actually know about, before your money is gone.

Electricals Ghana has inspected, rewired, and reported on properties across Greater Accra since 1987, including for diaspora owners. Call +233 23 063 0022.
