Free Signs Assessment
Check 6 physical signs you can see right now — socket positions, fuse board type, pendant cables, earth bonding, switch heights, and socket count. No guesswork, just the stuff that actually matters.
Rewire Signs Checker
Free Assessment Tool
Not sure if your house needs rewiring? This quick 6-question checker looks at the physical signs in your home — the stuff you can actually see — and tells you whether a rewire is likely, worth investigating, or probably not needed.
Takes about 90 seconds — no personal details required
What We Check
Sockets on or near the skirting board are a hallmark of 1950s–70s installations. If yours are down at floor level, the cables behind them are almost certainly the originals.
A modern-looking MCB board doesn't always mean modern wiring. Boards are often swapped before a sale — the wiring behind the walls stays the same.
One socket per room with extension leads running everywhere? That's a sign the original wiring was sized for 1970s demand — not 2026.
Rubber, fabric, or braided cable at the ceiling rose means single-insulated wiring — common in pre-1970s homes and a clear sign the installation needs updating.
Light switches mounted near shoulder or head height were standard decades ago. Modern switches sit at about 1.2 metres. The height tells you the era.
Green-and-yellow cables clamped to your water, gas, and heating pipes are a legal safety requirement. No bonding means the system predates modern standards.
Worth Knowing
This is something we see all the time — a homeowner buys a property, sees a shiny modern fuse board with MCBs, and assumes the electrics are grand. Then a few months in, they notice the sockets are on the skirting, the pendants are fabric-covered, and there's no earth bonding on any of the pipes.
What happened? The previous owner (or their electrician) swapped the fuse board before selling. It's a quick job — a couple of hours — and it makes the installation look modern. But the 40-year-old cables behind the walls haven't changed. The fuse board is the front door; the wiring is the house.
How to spot it: If your fuse board looks modern but you have a single row of 6–10 circuits for a 2–3 bedroom house, skirting-level sockets, high light switches, or no earth bonding visible on your pipes — the board was almost certainly replaced on its own. The wiring behind it needs investigating.
Common Questions
Our Rewire Checker focuses on symptoms — things like flickering lights, tripping breakers, burning smells, and warm sockets. This Signs Assessment focuses on the physical indicators you can see and check yourself — socket positions, fuse board type, pendant cables, earth bonding, switch heights, and the number of sockets per room. Together, they give you a comprehensive picture. If either tool flags concerns, we'd recommend a professional inspection.
Not necessarily. One of the most common things we see is a modern MCB fuse board fitted to old wiring. This happens a lot when a property is being sold — the fuse board gets swapped to make the electrics look up to date, but the cables in the walls are still 30, 40, or 50 years old. If your fuse board is modern but you're seeing other signs like skirting sockets, high light switches, or single-insulated pendants, the wiring behind the board is almost certainly the original. The fuse board is only one part of the system.
Skirting board sockets are sockets mounted at floor level, either on the skirting board itself or just above it. They were common in Irish homes built between the 1950s and early 1980s. The problem isn't the socket position itself — it's what it tells you about the wiring behind it. If your sockets are at skirting height, the cables are almost certainly the original rubber- or PVC-insulated wiring from that era, which degrades over time and can become a fire risk. It also means the circuits are likely undersized for modern electrical demand.
Earth bonding is the connection between your electrical system and the metal pipes in your home — water, gas, central heating, and oil. You'll see it as a green-and-yellow cable clamped to each pipe, usually near where the pipe enters the house or near the boiler. There should also be an earth rod (a copper rod driven into the ground outside, connected to your fuse board). Without proper bonding, a fault in your electrical system could make metal pipes and taps live — which is extremely dangerous. If you can't see any green-and-yellow cables on your pipes, that's a significant red flag.
When you look at the cable hanging from your ceiling where a light fitting connects, you're looking at the pendant cable. Modern cables have twin insulation — an inner layer around each conductor plus an outer sheath (the grey or white flat cable you see in newer homes). Single-insulated pendants have only one layer of covering, often made of rubber, fabric, or braided cord. These were standard in homes built before the late 1960s. Over decades the insulation breaks down, becoming brittle and cracked, which exposes the live conductors. If you can see rubber, fabric, or braided cable at your ceiling roses, it's a strong sign the wiring throughout the house is the same age and condition.
A full house rewire in Dublin in 2026 typically costs between €10,000 and €16,000 for a standard 2–4 bedroom home. A 2-bed is usually €10,000–€11,000, a 3-bed semi around €12,000–€13,000, and a 4-bed detached around €15,000–€16,000. This includes all new cables, a modern consumer unit with RCD protection, new sockets and switches, smoke alarms, plastering of all chases, and a Safe Electric completion certificate. Our free online estimator walks you through your home room by room and gives you a detailed price range.
Sometimes, yes — if the cables themselves are in good condition and the earthing is adequate, a fuse board upgrade on its own can bring the installation up to a safer standard. But if the wiring is rubber- or fabric-insulated, undersized, or showing signs of deterioration, a new fuse board on old wiring is a bit like putting new tyres on a car with a broken chassis. The fuse board protects the circuits, but it can't fix underlying cable faults. An electrician can test the insulation resistance of your cables to determine whether the wiring itself is still serviceable.
