Nationality application - P60s and payslips required?

[goldfish]

I will be using the nationality checking service (HSMP / Tier 1 residence + ILR held for one year). According to the instructions on my local borough website, P60s / payslips are only required if my passport does not cover the required 5 years. However, looking at some other boroughs nearby, they require P60s / payslips to be provided for nationality applications. Are they required or not?

Not required but you can take them with you (P60s) to be safe, NCS might not take them at all or might only take the last one you have.
