House Rewiring

How Much Does It Cost to Rewire a House in Ireland? (2026 Guide)

Interior lighting and wiring in a rewired home

“How much will it cost to rewire my house?” is one of the questions we’re asked most often. It’s a fair question — and an important one — but the honest answer is: it depends. Every home is different, and a good rewire is priced on the specific property, not a one-size-fits-all rate. This guide explains what actually drives the cost, so you know what to expect before you ask for a quote.

What affects the cost of a rewire?

A handful of factors make the biggest difference to the final price:

  • The size of the home. More rooms means more circuits, more cabling, more sockets and switches, and more labour. A two-bed terrace is a very different job from a five-bed detached house.
  • Full or partial rewire. A full rewire replaces all the wiring in the property; a partial rewire tackles only the parts that need it. If your wiring is sound in some areas, a partial rewire can save money.
  • Access and the age of the property. Older homes, solid walls, and tight or awkward spaces take more time to work in. A property that’s being renovated or is empty is usually quicker (and cheaper) to rewire than an occupied, finished home.
  • How much you’re adding. A rewire is the perfect time to add extra sockets, better lighting, USB points, outdoor power, or a new consumer unit. The more you add, the more you invest — but it’s far cheaper to do it during a rewire than afterwards.
  • Making good. Chasing walls for cables means some plastering and decorating afterwards. Whether that’s included, and to what standard, affects the price.

What should be included in a rewire?

When you compare quotes, make sure you’re comparing like with like. A proper rewire should include:

  • New wiring throughout (full) or to the agreed areas (partial)
  • A new consumer unit (fuse board) with modern RCD/RCBO protection where needed
  • Sockets, switches and lighting points
  • Smoke and heat alarm wiring
  • Tidy reinstatement and making good
  • Full electrical certification on completion

That last point matters more than people realise.

Why certification is non-negotiable

In Ireland, electrical work like a rewire should be carried out by a Safe Electric registered electrical contractor and certified. That certificate is your documented proof the work was done safely and to the required standard. You’ll want it for:

  • Insurance — insurers can ask for proof of safe electrical work
  • Selling your home — buyers and solicitors increasingly ask about it
  • Peace of mind — it’s confirmation the job was done right

A quote that’s suspiciously cheap and skips certification isn’t a bargain — it’s a risk.

Signs your home may need rewiring

You may need a rewire if you notice:

  • Old rubber, fabric or lead-sheathed cabling
  • A fuse board with old rewireable fuses rather than modern breakers
  • Frequent tripping, flickering lights or warm switches
  • Discoloured sockets or a burning smell
  • Not enough sockets for how you actually live
  • You’re renovating or extending anyway

As a rule of thumb, if your home is more than 25–30 years old and has never been rewired, it’s worth getting it checked.
