work out exactly what you would save over the next 6 months (not long till the renovations will be finished), and offset that against the costs of switch for such a short time as well. even though there isn't an early payment fee, there are still costs associated with registering the mortgage that you need to factor in.
Have you spoken to the existing mortgage holder and expressed your displeasure with the new rate? Its worth seeing if they will be flexible on their rate before remortgaging - if they figure out they'll lose you as a customer, they may be 'happy' to reduce the rate rather than have no income from you at all.
