Changing mortgage rates before completion

jmtr8000

Me and my partner are currently in the process of buying our first home, it’s a new build and we have a competition date of the 28/11/25. 

We have a mortgage in principle with an adverse lender because I have 2 Ccj on my credit file one will be at 6 year on the 9/8/25, the other will be 6 years old on the 16/10/25 and I also have a defaulted account on file from 5/11/25.
We are due to exchange contracts on the 25/8/25 so are currently in the process of applying for the mortgage. The rate I’ve been given is 6.5 fixed for 2 year with current rates it’s looking to cost me an extra £6000 over the short term, but am I right in thinking I can change rates with the same provider once I’ve exchanged contracts as I would assume I’d have a better chance of getting a better rate when these are off my file. I was just going to wait it out until they have gone off my credit file but I’ve been given a great incentive to buy. We can comfortably afford it so we will still be going ahead but would like to see what advice people have thanks everyone.

It depends on who the lender is.
Some lenders need a new application, others might be able to switch the product. 

Probably worth checking in with your broker. I would not mind my clients checking in with me on this, its part of the job.
