Life Assurance is quite simply, the foundations of financial planning. It ultimately offers protection in the event of your demise for various purposes, such as follows: Covering the debt on a mortgaged property. This protects your family and ensures a debt is not left in their hands. Covering the cost of your children’s education. This ensures that they can still go through education as you had originally intended. Providing an income for your family. Planning for inheritance tax (IHT) liabilities. We work closely with many global insurance providers and are able to scan the market place to ensure we can offer not only the best cost but also the best overall protection package that best suits your exact requirements.
