Lianna Tilley
Senior Mortgage & Protection Adviser
Hi, I’m Lianna.
I have lived in the Swindon area all my life and we recently relocated to Aldbourne, a pretty village in Wiltshire.
I have two boys aged 4 and 1 and a Cavapoo dog called Macie who can be found sat by my feet most days whilst I’m at work!
I am very family focused, my family is my world and they are what drive and motivate me.
I have been in financial services for over 16 years and have advised and helped people with their mortgage needs since 2014.
Along my journey I have managed to win numerous awards including mortgage adviser of the year up against a few hundred of my peers.
If you want to get a clear picture of the mortgage market and see how we can help you, get in touch.

Celia Ratajczak
Mortgage & Protection Adviser
Hi I’m Celia and I am proud to say I work with Jon and Lianna.
I started out my working life working in an estate agency and fell in love with the property business.
I wanted to progress so took my professional qualifications to become a Mortgage and Protection advisor.
I am a fitness fiend and can be found in the gym or running when I’m not helping my clients through the mortgage and home buying process.
I have recently entered a triathlon, so when not working will be training towards this goal.
I have a wealth of experience in the mortgage and property market, so you know you’re in safe hands.
