july/august is busiest time of year for my firm, working on the schools while they are shut.
i would strongly recommend to anybody that they get themselves on the approved contractor list for their local council. ring them up and ask how to do this, easily done.
the jobs come in slow at first while they trial you, you will have to prove yourself to them, being available 24/7 for example. once your in you can start to tender for the other services such as boiler servicing/maintenance of valves etc.
you can charge top rate of about 35 per hour but you do have to prove your worth to them, you also need top rate insurance and be totally quallified, ie if you touch an unvented cylinder you need the ticket, you do any electrics you need the ticket.
if you touch something your not ticketed for and are found out they will never use you again! everything has to be signed off and they are well up on legionella at the mo, so water regs reqd as well. but 1k on extra training will give you the window you need. maybe not for now but for 6months time.
hope that helps a bit. in the meantime, head up doggy paddling. good luck.
