If I'm on a 5 year fixed rate mortgage will I be able to add some more on to the mortgage/remortgage?

So stay with the same company and same mortgage deal but just add some money onto the mortgage? From a financial point of view we'd be allowed to borrow more money as current mortgage is tiny. But just not sure if we're tied into a set amount.

You don't add money to the existing one, you'll take out a second mortgage, at whatever terms they currently will offer you. So you might have a £40,000 mortgage at 4% a and a second £10,000 mortgage at 4.2% ( or whatever) hope that makes sense.

Ok, well good to know I can do it but pain it will be at a higher rate. I guess it needs to be with the same company?

Thanks.

It will depend on your mortgage company but mostly you will need to take the additional borrowing with the same company.
