Hi DCooper,
Thought i had managed to sort it but still struggling a bit and i'm sure it's a simple routing issue somewhere. Below is an email i sent over to Meraki support this morning.

How it’s setup currently
Office: MX65W gets ip through DHCP, a gateway of 10.14.130.250 and the DNS servers from DHCP which is 10.14.130.1 and 10.100.0.3 (this is in the other main office)
Office: MX65W (10.14.130.149) > Access Switch > Core Switch (Layer 3) 10.14.130.250 > ASA 10.14.130.253 > Internet
Home: MX65W (100.100.100.1) > Virgin Router > Internet
There is a static route in the core switch which is 100.100.100.0 255.255.255.0 10.14.130.149, so any traffic going to that subnet is routed through the Meraki MX device in the office.
The Site to Site VPN is reporting to by fine, the office MX65 can ping the internet and can ping 100.100.100.1 (Home MX) but not a laptop connected to the home MX which is 100.100.100.2. The home MX can not ping the internet, client computers on the 10.14.130 range, any subnets outside of the main office so the 10.100.0.0 subnet, but can ping the servers on the 10.14.130 range, all devices on 10.13.130, all the VOIP handsets on the 10.17.130 range. DNS is also not working at all so can’t ping host names from home.
From a home laptop connected to the home MX, I was able to use things like Citrix and connect to servers in the office but again through IP and not hostname. The DNS servers that are configured in DHCP on the home MX are 10.14.130.1, 10.100.0.3, and 8.8.8.8. These DNS servers do show up in IPCONFIG on my home laptop.

End of email.
Since the email, i've made both MXs static and hard coded the ips and dns in, same settings on both, no difference at all.
Office MX
ip: 10.14.130.149
subnet: 255.255.255.0
gateway: 10.14.130.250
dns 1: 10.14.130.1 (DNS in the office)
dns 2: 8.8.8.8
Home MX
ip: 192.168.0.5
subnet: 255.255.255.0
gateway: 192.168.0.1
dns 1: 10.14.130.1 (DNS in the office)
dns 2: 8.8.8.8
The static routes in the Core switch at the office (Layer3) is
ip route 0.0.0.0 0.0.0.0 10.14.130.253
ip route 10.0.0.0 255.0.0.0 10.14.130.244
ip route 10.250.130.0 255.255.255.0 10.14.130.253
ip route 10.251.130.0 255.255.255.0 10.14.130.253
ip route 10.255.236.0 255.255.252.0 5.20.87.176
ip route 147.152.20.0 255.255.255.0 10.14.130.244
ip route 147.152.22.0 255.255.255.0 10.14.130.244
ip route 192.168.0.0 255.255.0.0 10.14.130.244
10.14.130.244 is the MPLS to our WAN. 10.14.130.253 is the ASA to the internet. The main network for clients in the office is 10.14.130.0 which is VLAN14, the ip for vlan14 is 10.14.130.250 and when you telnet to that you get the core switch.
One of the things i tried lastnight was to put the Virgin Router into Modem mode, no difference at all.
