Get up to date

Many clients have a need for a “catch-up” project to get their books and accounts up to date. We will agree with you a plan to complete the project at the outset and agree a fixed price. Interest free credit is available for these projects – please ask for further details.

Easy Switch to Lilley & Co

With our easy switch service we will contact your outgoing accountant and do all that’s necessary for a seamless transition. As a client you don’t need to do anything but continue to run your business whilst we sort out the details.


We make the most of technology and use either Quick books online or Xero accounting packages to maximise efficiency. We can also show you how to process your receipts and invoices easily with the use of a smart phone. Imagine that? No more disorganised bags of receipts and invoices to worry about.

Trudi Lilley (ACMA, CGMA)

Trudi is a qualified accountant with over 20 years experience in commercial accountancy in both the UK and Guernsey.

Trudi feels it is very important to take a commercial approach to accountancy, never to just churn out numbers but always to question how the results could be better, what could be done to improve product margins, reduce costs and increase cash flow.

She moved to Guernsey in 2008 and started Lilley and Co in early 2014 with a clear vision to provide first class financial support at an affordable cost to small and medium sized businesses.

As well as myself and a small team, we have a network of experts who provide specialist taxation advice in both UK and Guernsey.

As our client relationship manager Adam is always happy to sit down and chat through our services over a cup of coffee and help you to decide on the best plan for you.

A. Carre

I just wanted to say that it has been a pleasure to work with you and that I finally feel that we are getting to a much better place accounts wise. This has been a source of great stress for me for months as I was struggling to find the right people on top of my capabilities in this department being limited. I feel the work you have done to date has been very very good.

You have helped us make a huge amount of progress, you ask all the right questions, look into everything for which I am hugely grateful.

Celia Munoz

Just wanted to let you know that I was really touched by you guys making such an effort and going the ‘extra mile’ in getting me sorted out, I really appreciate it as I have so much going on at the moment with the business and move next week too!
