BEFORE YOU BOOK

Check before you book

Safe Electric

Restricted to Registered Electrical Contractor (REC): a new circuit; a rewire; a new or replacement distribution board; work at the meter; a new supply to a bathroom or an outdoor area. Not restricted: replacing a light fitting like for like; replacing a socket front like for like.

Search the Safe Electric register for the name or the registration number before you agree a price. safeelectric.ie →

Completion Certificate

Issued by the Registered Electrical Contractor on completion of restricted works, once tested. It matters because it records that the work met the national wiring rules and was tested, and it is asked for on sale, remortgage and insurance.

Agree before the work starts that you will be handed completion certificate, and keep it with the house papers.

Insurance

Expect public liability; ask who the insurer is and for the policy number. From a company, ask for the insurer, the limit and the VAT number, and ask who actually attends: the team that turns up may be employed, subcontracted or both, and only one of those is supervised by the firm you are paying.

Ask to see the current certificate of insurance — the insurer's name, the limit and the date it runs to.

Trader or private seller

Under the Consumer Rights Act 2022 a trader must tell you they are a trader, and your consumer rights — work carried out with reasonable skill and care, and a cooling-off period on a contract agreed in your home or online — apply to traders and not to private sellers. On Locufy the trader status is shown on the profile.

Look for the trader badge on the Locufy profile, and ask anyone else for it in writing before you agree a price.

VAT

VAT at 13.5%, the reduced rate Revenue publishes for this service. Ask whether the price you were given includes it. A trader under the €42,500 registration threshold does not charge it; one over it must, and must show it separately.

Ask whether the figure you were given includes it, and for the VAT number if they are registered — Revenue publishes the rate for this service. revenue.ie →

“Are you on the Safe Electric register, and what is your number?”

A good answer: A number you can look up yourself before you agree a price — troubleshooting & Repairs — if existing network cabling is malfunctioning, technicians can diagnose and repair issues.

“Will I get completion Certificate, and when?”

A good answer: On the day the work is finished and tested, not posted on later — testing & Certification — after installation, network cabling must be tested for performance and reliability.

“How does complexity of the installation change the price?”

A good answer: Harder work needs better tools and more setting up. — ask before the quote rather than after.

“How does type of cabling required change the price?”

A good answer: A premium option takes longer to get right. — ask before the quote rather than after.

“How does length of the run needed change the price?”

A good answer: Work that spans two visits costs more than one long one. — ask before the quote rather than after.

“What is not included?”

A good answer: Network Setup — in addition to cabling, technicians often assist with setting up network devices like routers and switches — get the exclusions named in the quote, because a data cabling installer job is priced on what was agreed and not on what was assumed.

“Who insures you, and what is the policy number?”

A good answer: Expect public liability; ask who the insurer is and for the policy number — cable Installation — this includes the physical installation of data and network cables, such as Ethernet and fibre optic cables, in residential or commercial properties.

Getting the quote right

  • Complexity of the installation — harder work needs better tools and more setting up.
  • Type of cabling required — a premium option takes longer to get right.
  • Length of the run needed — work that spans two visits costs more than one long one.

  1. Look firstComplexity of the installation — harder work needs better tools and more setting up — that is what the data cabling installer is judging on the first visit, and a price given without it is a guess.
  2. Agree what is being doneType of cabling required — a premium option takes longer to get right — put in writing before anyone starts, because it is the document you both read back at the end.
  3. The work itselfLength of the run needed — work that spans two visits costs more than one long one — and anything found on the day that was not in that is priced before it is started.
  4. Check it togetherCondition of existing infrastructure — poor condition adds preparation before the work itself starts — walked against the written scope rather than against the feeling of it, while the data cabling installer is still there.
  5. What you are handedCompletion Certificate, the invoice and any guarantee on the workmanship and the parts, materials used — supplies are bought for the job and billed at what they cost.

AFTER

When the job is done

Keep Completion CertificateCompletion Certificate is issued by the trader, not asked for later — troubleshooting & Repairs — if existing network cabling is malfunctioning, technicians can diagnose and repair issues, because it is what a buyer's solicitor, an insurer or a lender asks for long after the data cabling installer has gone.
Test what was doneTesting & Certification — after installation, network cabling must be tested for performance and reliability — and something that does not work on the day is theirs to put right there and then.
Ask what the guarantee isOn the workmanship and on the parts, and for how long each one runs — they are usually different. network Setup — in addition to cabling, technicians often assist with setting up network devices like routers and switches — under the Consumer Rights Act 2022 what was agreed is what can be relied on.
Leave the reviewOnly a booked job can be reviewed on Locufy, which is why the score on a data cabling installer's card means something — cable Installation — this includes the physical installation of data and network cables, such as Ethernet and fibre optic cables, in residential or commercial properties.

Hiring a data cabling installer: questions people ask

The cost can vary based on the complexity of the installation, the type of cabling required, and the length of the run needed. Additional factors like the need for network configuration or testing can also impact the overall price.

The duration of a cabling installation can range from a few hours to a full day, depending on the size of the job and the number of cables being installed. A straightforward residential setup may take less time compared to a complex commercial installation.

Many professionals offer emergency or same-day services, particularly for urgent network issues. However, availability may vary, and such services often come at a premium price.

Yes, it is often possible to book several related services, such as network setup and troubleshooting, during a single visit. This can lead to cost savings and a more efficient use of time.

Search the name or the registration number. If the number does not resolve to the name on the quote, stop there.
