Be aware that fees for new deals are much higher than they were. We remaorgaged in April and had to pay abou £400 - I think the cheapest deal is now about £600, but if you want a good rate, many fees are in the £1500 region. We went to an IFA who was pretty helpful, but the first deal we went for was withdrawn from the market before we'd signed up. The one we got took about a month longer than predicted to set up, so we had to go onto SVR for a month which cost us about £100 extra in interest.
Agree with others though. What is happening now is no indication of how things could be in 12 months time.
