The advice given above used to be correct but is no longer the case. A lot of the banks recently have been pulling offers with little or no notice. If the loan is with Halifax/Bank of Scotland, Haven Mortgages, ICS, IIB Homeloans, Bank of Ireland, EBS , First Active then I would not just hold off and think that your rate would be the same all of the above have changed there rates in the last few months with little or no notice, they have not changed because of ECB but merely just increased the rate themselves. If your letter of offer is for a fixed rate you are especially at risk. Talk to your broker and ask if the rate you received and the letter of offer still stands, they used to be good for 6 months even 12 but this no longer applies.
