For most Dumfries & Galloway homes, yes. A battery stores surplus solar electricity for use in the evening, reducing how much you buy from the grid. This is especially valuable for rural off-gas properties with higher energy costs. 0% VAT applies to battery installations until March 2027. A survey confirms the right capacity for your usage.

Solar panels generate electricity during the day, but most households use the most electricity in the evening. Without a battery, surplus solar power is exported to the grid under the Smart Export Guarantee — useful, but you then buy electricity back at a higher rate in the evening.
A battery breaks this cycle. It stores your surplus solar electricity so you can use it when the sun is not shining. For rural properties across Dumfries & Galloway, many of which rely on expensive oil or LPG heating, this self-sufficiency can make a significant difference to running costs.
If you already have solar panels installed, a battery can usually be retrofitted. Your surveyor assesses compatibility with your current inverter and recommends the right battery capacity. Some older systems may need an inverter upgrade to support battery storage.

Battery capacity is measured in kilowatt-hours (kWh). A typical D&G home benefits from 5–10 kWh of storage, depending on solar generation and evening electricity use. Your surveyor recommends the right capacity after assessing your energy use, roof orientation, and generation potential.
0% VAT applies to battery installations until March 2027, whether installed alongside new solar panels or retrofitted to an existing system. See our guide to paying monthly for solar for finance options.
If you are considering a heat pump alongside solar panels, a battery becomes even more valuable. A heat pump uses electricity to heat your home, so storing solar electricity to run the heat pump in the evening maximises self-consumption and minimises grid purchases. This combination is particularly effective for off-gas properties in D&G.

For most D&G homes, yes. A battery stores surplus solar electricity for use in the evening, reducing the amount you buy from the grid. This is especially valuable for rural properties with high grid dependency. A survey confirms the right capacity for your usage.
Yes. A battery can be retrofitted to most existing solar installations. Your surveyor assesses compatibility with your current inverter and recommends the right battery capacity. Some systems may need an inverter upgrade.
Battery capacity is sized to match your solar generation and evening electricity use. A typical D&G home benefits from 5–10 kWh of storage. Your surveyor recommends the right capacity after assessing your energy use and generation potential.
Yes. 0% VAT applies to battery installations alongside solar panels until March 2027. This is applied automatically — no application needed.
