Can see this endinhg in tears.
I would suggest the OP go for the cheapest boiler (even one with a dent that fell off the back of a lorry) as NO boiler will is going to last when offered to a 10 year old system that has not been treated,
Could be this chap is short of work, starting on his own, or doing the graveyard shift. Either way there is chasm between a cheap job and a job well done. Cheap job equated to subsequent visits and cold house when the fitter, due to wafer thin profit, fails to turn up.
Then you are at the mercy of part changers who will not come cheap.
If you want good advice, get the present boiler fixed and start saving for a new boiler and start looking for someone wyho does quality instals (this will be verified by talking to friends, relatives and neighbours)
No wonder I do little or no instals.
