UK Postcode Format

Using the most recent version of Woocommerce.

Hello Support,

I was wondering if you could offer any advice I recently switched from opencart to woocommerce and am having a real problem with getting UK local postcode delivery to work. The configuration below which has worked fine on opencart and previously Magento. But can’t seem to get it working in woocommerce

For delivery to the following postcode’s the delivery charge is £4.99:

G1,G2,G21,G22,G3,G31,G32,G33,G34,G4,G40,G41,G42,G43,G44,G45,G5,G58,G64,G65,G66,

G67,G6,G69,G70,G71,G72,G73,G74,G75,G76,G79,G9,G90,ML1,ML2,ML3,ML4,ML5,ML6,ML7,

ML9,G11,G12, G13,G14,G15, G20,G23 ,G46,G51,G53,G60,G61,G77,G78,ML8,PA1, PA2,PA3,PA4

To the following postcodes delivery is £5.99

G63,G81,EH47,EH48,EH54,EH55,FK1,FK2,FK3,FK4,PA5,PA6,PA7,PA8,PA9,PA10,PA11

To the following postcodes delivery is £6.99

EH1,EH2,EH3,EH4,EH5,EH11,EH12,EH14,EH27,EH28,EH29,EH30,EH49,EH51,EH52,EH53,EH54,FK9, G82,KA1,KA2,KA3,KA4, PA12,PA13,PA14,PA15,PA16

To the following postcodes delivery is £8.99

EH6,EH7,EH8,EH9,EH55,FK8,FK10,PA17,PA18,KA5,KA11,KA12,KA13,

I have created 3 zones for each price band but if for example a customer has a postcode of KA1 1BA and I use the wildcard KA1* then it works fine. but if another customer has KA11 1BA then this also gets picked up then this also gets picked up so I then thought I would put in wildcard KA11* and put that above the KA1* but it was still catching the KA1 1BA which in a rural could be significant distance apart. What is the best way to setup uk local postcodes.Ideally there would be some way of identifying the space after the first part of the post card.

Hopefully that makes sense and any advice you could offer would be very much appreciated as I really do like this product over the others I have used.
