Change the tilt and turn window in the lounge. It is letting in drafts and noise. Also the wooden window sill inside is going at both ends so that too will need replacing.
Replace the bathroom radiator. This has needed doing now for 2 years and is getting very rusty.
Also, whilst it is being changed, we need to double flush the system to clean out the gunge that is building up and also change two bleed valves on the lounge radiator.
Onwards and upwards!
