Good morning A,
Thanks for your interest in Loveelectric and apologies for not getting back to you quicker on this.
In regards to your question, it ultimately depends on your taxable income, how much tax is paid and therefore how much can be saved. For most this is only from what they earn through PAYE. For extra income, the extra cost or benefit may only be realised when the self-assessment is submitted.
Hope this helps.
Kind regards,
Issy Russell
