Insurance
Insurance is a means of protection from financial loss. It is a form of risk management, primarily used to hedge against the risk of a contingent or uncertain loss. An entity which provides insurance is known as an insurer, insurance company, insurance carrier or underwriter

Compare gas and electricity tariffs and feel the power!
If you've felt a pang of nervousness before opening the latest correspondence from your gas and electricity supplier, you're living in fear of a monster energy bill.
It doesn't have to be this way.
According to Ofgem in June 2018, the average standard variable tariff (SVT) costs £1,172 per year, while the cheapest available tariff was around £797. It goes without saying that SVT’s are generally more expensive than other tariff types and around 57% of people with the 10 largest suppliers are on them!
There's no bonus for loyalty when it comes to energy- it really does pay to shop around and switch to the cheapest deal.
It's not just homeowners who can get in on the energy switching action either, tenants could switch and save on their gas and electricity too.
A mortgage loan or simply, mortgage, is used either by purchasers of real property to raise funds to buy real estate, or alternatively by existing property owners to raise funds for any purpose, while putting a lien on the property being mortgaged.
A mortgage is a debt instrument, secured by the collateral of specified real estate property, that the borrower is obliged to pay back with a predetermined set of payments. Mortgages are used by individuals and businesses to make large real estate purchases without paying the entire purchase price up front.
