final answer

Ok, so I have made my mind up: it is going to be a combi.
Any advice on the "best" one for 4 bed 2 bathrooms? Combination of price/quality/reliability/customer service?
Thanks to everybody who's helped me out thus far!

Well as we've said you're looking at something not really designed for your job so I'd be looking at a Combi with a store think most manufacturers will do one

Price/ quality/ reliability/customer service all equate to a good local heating engineer. When you find one, get quote for regular boiler and unvented cylinder.

Your putting a combi in that? Good luck!

So why is it when I have had 3 engineers come around (all highly recommended), I get 3 different answers? One says Worcester, one says Vallient and the last one said Baxi. Do they have their own agenda? Can I say that are 'good' local heating engineers if they have their own agenda. Are the boilers as good as each other or as bad as each other. There must be a definitive answer and there must be enough experience on this forum for an answer to be given.
Thanks.

Worcester highflow 550, expensive but will cope with two bathrooms as long as the incoming main is good. Also Worcester have the best after care of any boiler manufacturer, they actually honour their warranty and don't look for a reason to not repair it like many others.

Would 17-18L/min flow and a pressure of ~1.5bar be OK for a Worcester highflow 550?
Thanks.

no agendas every engineer has his favourite manufacturer and will aslways recommend that one first

Its capable of giving 25 l/min, the Highflow 440 may be better suited as it will give up to 20 l/min.

Op will not be told mate. Each to there own though. Every installer will have there preference and they will probably be able to offer extended warranties and the like through being a member of installer schemes etc further to above I would say Vaillant and I've never had a problem with their warranty or getting repairs done
