We found Heatable quotation tool online to be easy to use & understand. You could see straight away what the panels would look like on the roofs and they supplied a suggested panel quantity and value. We contacted them when we decided to proceed with several other providers, but they stood out for us. The sales person did not do a hard sale on us, but sent us various different configurations we could have and talked us through the options. We agreed to have 10 REA Power FUSION 2 REA-HD108N-C3-450 450W panels, 2 Battery Storage Sigenergy SigenStor BAT 8.0 (8.06kWh / 7.8kWh with 6kw inverter and a sigenergy gateway. We paid a deposit of 25% and was issued an insurance policy to cover this deposit. The surveyor said the house was ok to proceed. Heatable did all the application to Scottish & Southern Electric to get approval, & all the chasing, keeping us informed of progress. When we had approval they made a fitting date for the following week, the scaffolding arriving on the day before. The fitting team arrived on Wednesday morning and we were fully installed by Thursday pm. On Friday the electrician, Josh, came back and went through the installation in detail with us and has been on the end of the phone if we had any questions. We had one panel which had a scratch on it, which they changed immediately. Heatable helped us through obtaining the export numbers, providing documentation and have been there on the end of the phone anytime we’ve needed support. Cost as agreed.
