Barry

Trina and Ecoflow in Barry

The smoothest experience, from the first chat with Phoenix at the door through to Danny the installer. Even the scaffolding team were extremely considerate. It took a few hours longer than expected but was 100% worth it.

Penarth

Nicola's install in Penarth

I had 10 panels fitted and am pretty self-sufficient already. The team communicate well, are professional and friendly, and did a really neat job. They came when they said they would and have kept in touch since.

Zoe's solar and battery, Penarth

Altum were great from the sales call through to set-up. Communication was excellent throughout, and if there was any issue they were on hand by email, text or phone. The electricians and installers worked hard and quickly.

Lalu's Trina and Ecoflow system

The whole experience was brilliant and the team's approach involving Wasim, Nick and Danny the electrician was excellent. I would highly recommend Altum to anyone thinking of going solar.

Wenvoe

Trina and Ecoflow in Wenvoe

Wasim took time face to face to explain the options and earn our trust. The price compared well with other quotes and Altum did not try to oversell with more panels and bigger batteries than we needed. The personal touch overcame our reservations.
