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 idea behind this is quite simple. You give up part of your salary and, in return, your employer gives you a non-cash benefit, such as childcare vouchers, or increased pension contributions. Once you accept a salary sacrifice, your overall pay is lower, so you pay less tax and National Insurance. Because your salary is lower as a result of salary sacrifice, any life cover through a scheme at work could be less if itâs based on your lower salary. 2  Itâs worth checking â some employers do provide life cover at your original salary so you donât lose out.
