Can’t afford new neighbours requests.

You don't say how old your parents are but some AgeUK groups have gardeners and house maintenance workers who work for very reasonable rates.

Until the intervention of COVID most local authorities ran a 'Care and Repair' service.  This gave access to vetted tradespeople who undertake a limited range of work free of charge apart from materials.  My late DM used this to attach new door handles, change light bulbs (12 foot high ceilings) and install hand rails by the outside stairs.

They don't do electrical, gas or plumbing work though do have recommended companies for that. 

It may be worth exploring if the services are back up and running yet.
