As CNG above.

Definitely fit a new timing belt as the current one will be 'set' Drain the oil - I would leave the plug out overnight - and change the filter. Remove the spark plugs and put a teaspoon of oil in each bore and remove the fuel pump fuse. Spin the engine over on the starter until the oil light goes out. Replace the plugs - preferably new - and the fuel pump fuse and try to start it. Once you have it running and ready for the MOT, change the oil and filter again and you should be good to go.
