“Harry at Voltnet Engineering Ltd did an excellent job upgrading my consumer unit. He was professional, reliable and clearly very knowledgeable. The work was completed to a high standard, and everything was left neat and tidy afterwards. I also really appreciated how organised the service was — all the relevant certificates and documentation were provided promptly after the work was completed. Communication was clear throughout, and I felt confident that everything had been done properly and safely. I would definitely recommend Harry and Voltnet Engineering Ltd to anyone looking for a trustworthy and professional electrician.”

Friendly, professional, and trustworthy—I wouldn’t hesitate to recommend Voltnet to anyone looking for quality electrical work.”

“We had Voltnet Engineering Ltd install a car charging point at our home in Chelmsford and it was a brilliant experience from start to finish. They were punctual, tidy, and explained everything clearly with no pushy upselling. The install itself was neat, all the cabling was run cleanly, and they made sure to minimise any disruption. The charger works perfectly and they took time to show us how to use the app and schedule charging. Great communication, fair price, and proper certification paperwork provided on the day. Would 100% use them again.”

“Very professional work, reliable, explained every detail, tested all the connections, charged an affordable price and provided all required certifications. Would highly recommend to anyone. Thank you to both Harry and George.”

“This is the second time we’ve used Harry and we can’t fault his work. Such a friendly, knowledgeable guy. Very reasonable and professional. Wouldn’t hesitate to recommend him to friends and family. Thank you Harry.”

“Harry and the boys have recently installed an EV charger at my house... Definitely not a straight forward install, as I wanted my charger installed quite far away from my meter, and they have done a cracking job! The job required trenching my front garden and you wouldn't have even known it had been done. Very happy with install and a the boys did a brilliant job cleaning up after. All necessary documentation and certificates provided very quickly after job was completed. Highly recommend!”
