Before you accept a quote, check:
- Price: does it include the battery, inverter, installation and commissioning? Is VAT included or shown separately?
- Brand and model: exactly which battery and inverter are being fitted?
- Warranty: who covers what, and for how long? Read the terms.
- Installer: are they certified, insured and based near you?
- After-sales: who do you call if something goes wrong?
Solar Heaven quotes the battery, inverter, installation and commissioning in one price, with 0% VAT on battery storage. We also explain warranty terms for each brand before you commit.
