Personal recommendation from a trusted friend is always the best way to find an IFA. Failing that you can go to unbiased.co.uk and find a choice of IFAs. You can filter your search to find appropriately qualified advisers and the results are listed in proximity order with those closest to you listed first.
When you meet the adviser for the first time your gut reaction is a good gauge. If during the first meeting you like, trust and respect them then you won’t go far wrong.
Qualifications are important but they are not the whole story. Does the IFA explain things simply and clearly?
