How much does it cost to add extra sockets in Ireland?

A fused spur taps off an existing socket outlet using a fused connection unit (FCU), usually rated at 13A. It is the lowest-cost option and the quickest to install because it requires no new cabling back to the fuse board. A spur can feed one or two additional sockets and is well suited to adding a socket in an adjacent room or on the other side of the same wall.

The limitation is that the spur shares the 13A fuse of the FCU, which means it cannot support high-draw appliances. For televisions, lamps, phone chargers, and similar household loads it is perfectly adequate. For a socket that will regularly run a washing machine, tumble dryer, or microwave, the ring extension or dedicated circuit is a better choice.

Adding a new socket into the ring circuit proper maintains the full 32A protection of the ring and is the preferred method when you need sockets that will handle higher loads or when you are adding several sockets in a new area. The electrician breaks into the ring at the nearest convenient point and loops the new socket into the circuit. The ring must still form a complete loop back to the fuse board.

This method involves chasing cable into the wall, which means plasterwork repairs are required afterward. The plastering is typically a separate cost unless your electrician includes it in the quote. Always confirm this before work begins to avoid an unexpected bill.

Some equipment must have its own dedicated circuit run directly from the consumer unit. This is required for EV chargers, range cookers, electric showers, workshop equipment, and any other high-draw single appliance. A dedicated circuit is typically a radial circuit (single cable from board to outlet) protected by its own MCB in the fuse board.

Running a new circuit from the fuse board is notifiable work in all circumstances. Your RECI-registered electrician will notify the work to Safe Electric and issue a completion certificate on finishing the job. Adding a circuit also requires that there is a spare way in the consumer unit; if the board is full, a new or larger unit may be needed.

A socket in the same room as an existing outlet costs far less than one on the far side of the house or in a converted garage. Every additional metre of cable run adds cost, and long runs through floors or under screeds add significantly to the labour.

Stud partition walls are quick and clean to work with. Solid blockwork walls require a chase cutter or SDS drill to create channels for the conduit and cable, adding 30 to 60 minutes per run and creating plaster repair work afterward. Dense concrete is the most expensive to chase.

Electricians charge a call-out element on top of per-socket rates. Getting three or four sockets installed in a single visit is considerably more economical per socket than booking one socket at a time. If you anticipate needing more sockets, plan them all into one job.

Any new or extended circuit in a kitchen, bathroom, or outdoor location is notifiable under the Irish Building Regulations regardless of size. This adds a small administration cost but does not change the labour rate significantly. The key point is that only a RECI-registered electrician can issue the required completion certificate.

Most electricians do not include plastering in their quote as standard. Chase repairs in blockwork walls typically cost €60–€150 per repair when carried out by a plasterer. Confirm at quoting stage whether making good is included or whether you need to engage a plasterer separately.

Dublin electrician rates run 20 to 30 percent above the national average, driven by higher labour costs and demand. Rates in Mayo, Roscommon, and Donegal are typically the most competitive. Always get two or three quotes for jobs over €300.

NOT notifiable

Adding sockets in living areas

Extending an existing ring main or adding a spur in a living room, bedroom, hallway, or dining room in an existing dwelling is not notifiable, provided no new circuit is created. Work must still meet IS 10101 and must be carried out by a RECI-registered electrician.

NOTIFIABLE

Kitchen and bathroom circuits

Any new circuit or extension to a circuit in a kitchen, bathroom, or utility room is notifiable under Irish Building Regulations regardless of the nature of the dwelling. This includes adding a socket in a kitchen counter run or near a bathroom shaver unit.

NOTIFIABLE

All outdoor work

Any new socket or extended circuit in an outdoor location, shed, garage, or outbuilding is notifiable. Outdoor circuits require RCD protection and weatherproof fittings rated to at least IP44, and a completion certificate is mandatory for this category of work.

NOTIFIABLE

New builds and major renovations

If the socket work forms part of a new build or major renovation where a Commencement Notice has been submitted, all electrical work on the project is notifiable and must be completed by a RECI-registered electrical contractor under the Building Control (Amendment) Regulations.

Verify before hiring

Check your electrician at safeelectric.ie before work starts. RECI registration is public and searchable by contractor name or company. Do not rely on business cards alone.

Get a written quote

Always get a written quote that specifies the method (spur, ring extension, or new circuit), the number of sockets, and whether plastering is included. A verbal quote leaves room for misunderstanding on the final bill.

Certificate on completion

For notifiable work, your electrician must issue a RECI completion certificate. Keep this with your property documents. Your insurer and any future buyer will need to see it if the work is ever queried.

Can I just plug in a multi-socket adapter instead of adding a new socket?

Multi-socket adapters and extension leads are a workable short-term solution for low-draw devices, but they are not a substitute for a properly installed socket. Daisy-chaining multiple adapters or overloading a single socket with high-draw appliances (heaters, kettles, washing machines) is a fire risk. If you find yourself relying on extensions permanently in a room, it is worth the cost of getting a proper socket or two installed by a RECI-registered electrician. IS 10101 recommends a minimum number of socket outlets per room in a new installation, and older Irish homes often fall well short of this.

How many extra sockets can I add to an existing ring main?

There is no fixed maximum number of sockets on a ring circuit, but there is a maximum floor area the ring is permitted to serve: 100 square metres under IS 10101. In practice, the limiting factor is usually the load on the ring. If the ring is already heavily loaded (many high-draw appliances), your electrician may recommend a second ring rather than further extending the existing one. This is one reason why a qualified electrician will test the existing ring before adding to it, rather than simply connecting new sockets without assessment.

Do I need planning permission to add sockets?

No. Adding electrical sockets is an internal alteration that does not require planning permission under Irish planning law. The requirement is for Building Regulation compliance (notifiable works notification where applicable) rather than a planning application. The two systems are separate. If you are adding sockets as part of a larger extension or conversion project that does require planning permission, the electrical work is captured under the Building Regulation compliance for that project.

How long does it take to add sockets?

A fused spur from an adjacent existing socket in a stud partition wall can be completed in under an hour. Extending the ring main through blockwork walls with chasing, cable installation, and making good typically takes half a day per socket location, plus time for plaster to dry before redecoration. Multiple sockets in one room or on one floor can often be batched efficiently in a single visit. Always confirm the estimated duration with your electrician when getting a quote so you can plan access accordingly.

What is the difference between a spur and extending the ring?

A spur branches off the ring circuit at a single point and is protected by a fused connection unit (usually 13A). It can serve one or two additional socket outlets but cannot be further extended. Extending the ring adds the new socket into the ring circuit itself, maintaining the full 32A protection of the ring and allowing the ring to be extended again in future if needed. Your electrician will recommend the appropriate method based on the load the new socket will carry and the condition of the existing ring. A spur is cheaper; a ring extension is more flexible and better for higher-load locations.
