It's usual to "take it into account" simply by landing on the runway. The numbers you have to remember are the ones for levels above the airport. For VFR, you need traffic pattern (circuit) altitude or height. For IFR, you need decision (or minimum descent) altitude or height.
You still need to check and remember the numbers when using QFE. The difference is that they are often, but not always, the same when using heights (1000 ft pattern height, 200 ft decision height etc.). The "but not always" part makes me think that using QNH is less likely to catch you out!
