I didn't think you could get MB1 anymore ?

OP X100 1 ltr per 10 rads

4 liters of MB1 for up to 10 rads. We've worked in numerous properties with more than 20.;)

The OP says:
Does not compute. How do you get 8 litres of fluid into a sealed heating system without removing 8 liters of fluid from the sealed heating system?

O.P.: MB1 is a 'heritage product' and can be replaced by the F1 Liquid, Super Concentrate or Express.

I was referring to the concentrate in cartridge form. That would I think be less than a litre.

OP said

Fernox MB-1. 8 litres

no mention of 'concentrate in cartridge form' (another expensive option) made by OP or you.

As SCRGI suggested in his post use X100, the MSE option, on offer at Screwfix for £11.99
