Need currency pound symbol before amount

[ianhaney]

I need to display a pound currency symbol before the amount that is calculated

Below is the code I currently have

<th class="text-right py-1 px-2 grand-total">0</th>

function calc(){
        var grand_total = 0;
        $('table#list tbody input[name="total[]"]').each(function(){
            grand_total += parseFloat($(this).val())
            
        })
      
        $('table#list tfoot .grand-total').text(parseFloat(grand_total).toLocaleString('en-gb', {style:'decimal',maximumFractionDigit:2}))
        $('[name="amount"]').val(parseFloat(grand_total))

    }

I'm not sure where to add it within that code, can anyone help please
