Employees can work up to 10 days during their maternity or adoption leave. These days are called ‘keeping in touch days’. Keeping in touch days are optional - both the employee and employer need to agree to them. The type of work and pay employees get should be agreed before they come into work. The employee’s right to maternity or adoption leave and pay is not affected by taking keeping in touch days.
It may be different where you work. At my work if I work any KIT days I get paid statutory if I'm receiving full pay already and full pay if on statutory. I can also choose to not get paid and keep them as time off in lieu when I return.

Yeah at my work if you are already receiving full pay then you don’t get paid anything for a KIT day but if you’re on statutory or nil pay then you get full pay for a KIT day. That’s a good idea about the time off in lieu, I may see if I can do that.
You would have to check your maternity contract. Im honestly not sure, i imagine it would entirely depend on what your company has agreed.
