Customer reviews

Smart Switch upgrade (2G to 5G) I just wanted to take a moment to share how impressed I was with Paul from your company, who came to my home this morning to upgrade my smart device from 2G to 5G. From the moment he arrived, Paul was polite, respectful, and genuinely pleasant to be around. He made a point to explain what he was doing, worked efficiently, and still found time for a friendly, natural conversation. It wasn’t forced or rushed, just a lovely, smart chat that truly made my day. It’s rare to meet someone so skilled at their job who also brings such a warm, positive presence into a customer’s home. Paul is the kind of employee every company should treasure and take good care of. Thank you, Paul, for a job well done and for brightening my morning. Please make sure your management knows what a gem they have. Sincerely, Ovi

I had a very positive experience with the customer support representative. She was extremely polite, patient, friendly, and very resourceful throughout the conversation. I had quite a lot of questions and concerns, but she handled everything calmly and professionally without rushing at any point 🤠🤠. She explained things clearly, was very supportive, and helped resolve the issue quickly and efficiently. Her positive attitude and willingness to help made the whole experience smooth and stress-free.^^ Really appreciate the excellent customer service and support provided. Thank you once again! ☺️

A very kind and sweet gentleman, by the name of Kyle, visited my apartment to fix a fault with the boiler. I am so pleased with the result as he managed to fix it in no time. He was kind, patient and professional. A true asset to your company. I would recommend him and Switch2 to everyone.

Suzana Islam 8 Dec 2025

I spoke with Joe from Switch2 and he was extremely helpful—truly a credit to the team. He clearly explained what Switch2 provides for the apartment I’ve just moved into, updated my contact details, set up my direct debit, and arranged an engineer visit for an issue identified on move-in. Fantastic service and a real asset to the organisation.
