Electrical Installation
Walsh Electrical Services carries out electrical installation work (including new wiring and also rewiring; minor works; additions and alterations to existing electrical installations; fire alarm and emergency lighting installations; electric vehicle charging instalations, and other electrical installation works) – whether for 400V three-phase (sometimes erroneously referred to as 415V or 380V), 230V single phase (also erroneously referred to as 240V or 220V) or for 110V Reduced Low Voltage (RLV) centre-tap earthed installations
Whether domestic; commercial; industrial; agricultural, etc. work is carried out to the current Edition of BS 7671 (IET Wiring Regulations) or I.S. 10101 (NSAI National Wiring Rules) and other relevant Standards. We provide full certification to the person ordering the work upon completion. This is a requirement of the Wiring Regulations/Wiring Rules under all circumstances.
We carry out extra-low voltage (ELV) installations in addition to low voltage (LV), and are competent to deal with different Earthing arrangements, e.g. TN-C-S (whether Neutralised, Protective Multiple Earthing (PME) or Protective Neutral Bonding (PNB)), TN-S and TT (Direct). N.B. In the south any Direct Earthing will need to be Neutralised.
Removal of waste produced can be provided as an optional extra service as we are a licenced upper tier carrier and broker of controlled waste.
Smoke, Heat & Carbon Monoxide (CO) Alarms
We can supply and fit mains-powered and battery backed-up smoke and heat detection. These are interlinked to ensure that if any device is activated the other alarms will also sound to facilitate early warning. These are installed to the appropriate Standard (BS 5839 or I.S. 3218) and certified to the relevant Standard. We can also supply and fit carbon monoxide (CO) detection. Carbon monoxide, known as the "Silent Killer", is an odourless, colourless and tasteless – yet poisonous – gas. This includes installations in private tenancies to comply with The Smoke, Heat and Carbon Monoxide Alarms for Private Tenancies Regulations (Northern Ireland) 2024.
CO Alarms should be fitted in every room containing a fuel-burning appliance. They should also be located in or near bedrooms, and in any room through which a chimney or flue passes through. The CO detectors can be interlinked, but where they are also interlinked with smoke/heat detectors then an indicator of the source of alarm should be fitted as different responses are required for fire detection and carbon monoxide detection.
Where fire detection is interlinked with CO detection then an indicator of the source of the alarm should also be fitted. This is due to the fact that different responses are required depending on whether there is the presence of fire or high levels of carbon monoxide.
We are an Aico Expert Installer, and have also completed their City & Guilds Assured qualification. Aico is a wholly owned subsidiary of Ei Electronics in Shannon, Co. Clare. These detectors are sold in the south of Ireland under the Ei Electronics brand.
Inspection & Testing
At Walsh Electrical Services we carry out initial verification of all new electrical installation works, complete with the issuance of relevant certification. We also carry out periodic inspection and testing, furnishing the person ordering the work with the appropriate report. Furthermore, we can advise on any necessary remedial work to ensure the safety of your electrical installation. This includes both non-domestic and domestic installations (including those required by The Electrical Safety Standards for Private Tenancies Regulations (Northern Ireland) 2024). Please visit our dedicated Inspection & Testing page for further information.
Where we come across a dangerous situation which you elect not to rectify then we may issue an NICEIC Electrical Danger Notification or an ECA Report of Potentially Dangerous Electrical Condition, or a RECI Notice of Potential Hazard.
Entertainments Licence (Co. Derry and surrounding areas)
As an NICEIC Approved Contractor and an ECA Registered Member we can provide all necessary certificates and/or reports for the electrical installation, emergency lighting and fire alarm systems required for an Entertainments Licence.
The Council's Guidance Notes state that "Electrical and Emergency Lighting certificates should be completed by an approved contractor on the roll of the National Inspection Council for Electrical Installation Contracting, a member of the Electrical Contractors' Association or a Member of the Institute of Electrical Engineers." Walsh Electrical Services is an Approved Contractor on the roll of the National Inspection Council for Electrical Installation Contracting (NICEIC), a member of the Electrical Contractors' Association (ECA), and the Proprietor is a Technician Member of the Institution of Engineering and Technology (TMIET) – formerly known as the Institution of Electrical Engineers (IEE).
RECI Certs in the 26Counties
As a RECI REC, all of the Controlled Electrical Works and Restricted Electrical Works carried out by us are fully certified with the appropriate ETCI certificates and reports (RECI Registered and Safe Electric Registered).
N.B. The Declaration of Compliance with ET101 for Minor Electrical Installation Works has since been replaced with a Completion Certificate for Existing Installations (Cert No. 3).
ESB Reconnections
We can facilitate the reconnection of your electricity supply from the Distribution System Operator (DSO) — the Electricity Supply Board (ESB).
ESB Networks (ESBN) will require a Completion Certificate (RECI cert) from a Registered Electrical Contractor. We will need to visit the premises on at least two separate occasions for this. As the installation needs to be re-certified, additional works may be necessary depending on the condition of the electrical installation and its compliance with the National Wiring Rules when it was constructed. Any new work carried out during the works must comply with current Wiring Rules.
Any price quoted for these works is for the inspection, testing and certification only — additional works can only be quoted following inspection and testing. Should additional works be required and these be declined, payment will still be required for the inspection and testing carried out, as will the certificate cost if the PreConnection certificate has been issued.
Contact us to arrange this.
Portable Appliance Testing
Walsh Electrical Services provide a Portable Appliance Testing (PAT Testing) service, complete with certification. We can also carry out repairs to equipment which has failed a PAT test where possible, and if required.
All Portable Appliance Testing conforms to the 4th Edition of the Code of Practice for In‑service Inspection and Testing of Electrical Equipment, published by the Institution of Engineering and Technology (previously the Institution of Electrical Engineers).
Visit our dedicated PAT Testing page for further information.
Electric Vehicle Charging Equipment (EVSE) Installation
We supply and install Electric Vehicle Supply Equipment (EVSE) — commonly referred to as EV charging points.
In the 26Counties you may be eligible for a €600 grant towards the cost of fitting this from the SEAI. As we are an OLEV Authorised Installer, you may qualify for an OLEV grant of up to £350 per eligible chargepoint for installations in the north.
Electric Vehicle Charging Points in Donegal & Derry!
Emergency Call‑Outs in Derry/Donegal
Walsh Electrical Services provide an emergency call‑out service both North & South of the border. This includes fault finding, emergency repairs and an out‑of‑hours service.
A call‑out fee applies. Call‑outs outside of normal working hours — including weekends and bank holidays — are subject to a higher call‑out fee and hourly rate. Where a repair is declined, fault diagnosis remains a chargeable service. Where it is not possible to complete a repair (e.g. due to non‑availability of materials) we will endeavour to carry out a temporary repair where this is both safe and feasible.
Controlled & Restricted Electrical Works
Definitions as set out by the Commission for Energy Regulation, governing what counts as Controlled Works, Restricted Electrical Works, and Minor Electrical Works under the National Wiring Rules.
Controlled Electrical Works
Major installation works — new fixed installations requiring connection to the network, distribution board work, additional circuits, and inspection/testing/certification of existing installations under Chapter 62 of ET101.
Restricted Electrical Works
The domestic‑property equivalent of Controlled Works — new fixed installations, distribution board work, additional circuits, and certification of existing installations in a Domestic Property.
Minor Electrical Works
Replacing an accessory such as a light switch, replacing or relocating a light fitting on an existing circuit, or adding a socket to an existing radial circuit.
