“Carrington Blake Accountancy saved me when I desperately needed an accountant to help me do my Self Assessments at very short notice before the deadline. Unfortunately, I am not the most organised of individuals and left it to the very last minute with receipts everywhere I knew I was definitely going to be fined for late submission and to be honest gave up. I was then recommended Carrington Blake Accountancy and thought well what do I have to lose? Surprisingly the consultants took on my file organised my receipts in just 2 short days and submitted my assessment in on time, says it all really.”
