According to FoodSafety.gov, the most important thing is to keep refrigerator and freezer doors closed. If they stay sealed, your fridge can keep food cold for about four hours, and a full freezer for about 48 hours (24 hours if it's half full).
That means youâll only receive tax relief on pension contributions of up to 100% of your earnings or Â£4,000, whichever is the lower. Whether the lower Â£4,000 annual allowance applies depends on how you access your pension pot and there are some complicated rules around this.
The amount that you have to contribute is outlined in a Rates & Adjustment Certificate that forms part of the formal valuation of the Pension Fund. The date of the last valuation was 31 March 2016 with employer contribution rates being set for the period 1 April 2017 to 31 March 2020.
