Thanks for the suggestions and especially the reminder of the actifry! After some research on them, I've decided that the things are too bulky (small kitchen) and take too long to cook up a batch of chips (decent chippy would be a quicker trip!) so will stick to the current system of either wedges or chippy chips. Most frying duties are handled by George Foreman - well, grilling duties! - so it would be almost only chips in the fryer and the £160 for an actifry (would get the family version for the auto-stop feature and bigger batch possibility!) will pay for a lot of portions of chippy chips (and fuel to collect).
Sausages here get browned in a dry frying pan then baked in the oven. When I lived in a shared house, we did all the fry ups in a deep fryer, bangers, chips, bacon and even fried eggs (although I didn't eat eggs and still don't)! Helps explain my shape to some extent, although that's changed a bit in recent months.
FTR, the wedges we do are done in the oven - the spuds are wedged into 1/8ths then tossed in about a tablespoon of oil with paprika, salt, pepper, a few drops of balsamic vinegar and a little tzatziki mix (mainly garlic powder). To do the tossing, we put the mix in a big freezer bag and mix it well before lobbing the wedges in and tossing them until well coated. Pre-heated oven for 25-30 minutes and Robert's your parent's sibling!
