I am looking for weekday pass which can be used for zone 1-3 only on
weekdays which is less than 26£. I have got a monthly pass, but dont
use it a penny during the weekends.

Prepay single journeys zone 1-3 are £2.50 a pop between 7am and 7pm (£2
all other times) so even if you just used it twice a day during peak
periods i.e. to work and back, it wouldn't work out cheaper than a monthly:

PrePay: £25/ week
Monthly: £23/ week
