First direct evidence submission timeframe for new applications

Skintsaver

I’ve done the maths on my situation and it actually works out better for me to exit my current Nationwide mortgage 1–2 months early and just pay the £500 ERC. That’s only based on the assumption that mortgage rates stay around 0.5% higher than they were last week, when I applied for a new 5‑year fix with First Direct at 3.89% (fee‑free).

My existing Nationwide mortgage is 0.94% and ends on 01/11/2026.My First Direct application currently has a preferred start date of 02/09/2026.

Ideally, I want the FD start date to be as close as possible to (or even after) my Nationwide expiry. That way I can properly assess whether it’s better to stick with Nationwide and cancel the FD application, especially if rates settle back down over the next 4–8 months (unlikely, but possible).

FD say the following:

“We can only issue a mortgage offer once your application has been approved.”

“Mortgage offers are valid for 6 months from the date they’re issued.”

This is what I’m trying to understand.

Does this mean that the 6‑month validity only starts once they’ve checked my payslips, bank statements, etc., and actually issue the offer?Or does the preferred start date I selected stay fixed regardless?

If the offer date does move based on when the offer is issued, then in theory I could delay sending my documents so the offer is issued later, which would push the 6‑month window closer to my Nationwide end date.

So my main question is:

How long can I realistically delay providing payslips/bank statements before First Direct close the application?

I’m not trying to mess them around — I just want the offer window to line up with my current fix expiry so I can make the best decision when the time comes.

Anyone had experience with this or know how strict FD are with document timelines?

You really need to ring FD & ask the mortgage team to get the correct timings.

I will do, I spoke with them before my application, I can cancel at anytime. My thinking is that If rates creep up over next few months Im protected but if they drop or rates mean I'm break even then I'll re apply elsewhere and cancel
