If you're a charity and you think you have overpaid on energy VAT, this can be reclaimed. VAT on energy consumption for the charity sector can be backdated for four years, and the rebate will be returned to you via HMRC or your business energy suppliers. This process is known as VAT relief.
If you have just discovered that you may be eligible for a discount on business energy prices, remember to backdate your claim four years to receive the maximum rebate owed to you - also, take the opportunity to enquire about renewable energy, and visit BEUK for energy-saving tips.
