Hi, First of all...it depends how much equity you may have in your property.
7.95% is a nasty variable rate, and to be honest, even if you remortgaged to another lender and went straight on to their variable rate, you could save a lot of money!! E.g. Nationwide directly will offer a variable rate of 6.49% with no fees, free legal fees and a free valuation with no tie ins! Most lenders will offer better rates if your loan doesnt exceed 75% of your property value also, so bare this in mind then making a decision.
with regards to fixed rate changes etc....I cant really comment as it will depend on your current situation with disposable income etc. Things are certainly looking like the base rate may possibly fall, so possibly a tracker rate could be a good option for the next few years. Again, it will depend on personal circumstances.
It will probably be worth speaking to a broker, but to give you some ideas, HSBC direct have some great trackers with low fees at the moment, and they have no tie in's so you can leave at any time with no redemptions...C&G (lloyds TSB) also have some great fixed rates at the moment for customers under 75% Loan to value.
If you want to come back with a few scenarios including your property value and current mortgage, then it may help me with guiding you etc.
