What Our Customers Say About Ian Walsh

“I would highly recommend Ian Walsh of Renew Electrical. Ian carried out a full rewire of our property and was honest, thorough, and professional throughout the entire job. Everything was completed to a very high standard, and I really appreciated the clear communication and complete transparency around the pricing. It's not always easy finding someone you can trust with work like this, but Ian was excellent from start to finish. We plan to extend our property again in the future, and Ian will definitely be a key part of that work. I wouldn't hesitate to recommend Ian and Renew Electrical to anyone looking for a reliable, professional, and trustworthy electrician.”

“Ian from Renew Electrical explained everything in detail before starting the job. He checked everything which included the wiring from the meter to the fuse box to make sure it was the correct cable because of the age of the house. He was punctual, professional and did a neat job as you can see from photo. I would thorough recommend him to anyone.”

Meter Tails Upgrade FAQs

What is an ESB meter tails upgrade and swap?

An ESB meter tails upgrade replaces the main incoming cables connecting your outdoor ESB electricity meter to your indoor consumer unit with 25mm² double-insulated conductors.

Do I have to contact ESB Networks for a meter tails swap?

We coordinate the entire upgrade and issue the required Safe Electric certification so your supply remains 100% compliant with ESB Networks and IS 10101 standards.

Why is a 25mm² meter tails upgrade necessary for an EV charger or heat pump?

A 7.4kW EV charger or heat pump draws up to 32A continuously for hours. Older 10mm² tails can overheat under sustained load, making 25mm² tails and a 100A isolator essential.

What is the difference between a meter tails swap and a full house rewire?

A meter tails swap upgrades only the primary incoming feed between your meter cabinet and consumer unit in 2 to 4 hours, whereas a full rewire replaces all internal room circuits.
