Boiler quotes - confused
Hi all. I’m looking for some advice and possibly some re-assurance. I’m really confused and don’t have anyone to turn to or to ask. I’m completely in the dark and wanted to get your thoughts. I don't have any building or plumbing knowledge, so apologies if I can’t provide any more information that the basic info in my post. I just wanted to get your thoughts and ask if this seems reasonable and comprehensive.
I’m looking to replace my traditional boiler with a combi boiler system.
My house is a two storey terraced house in South London, 4 beds and two bathrooms. We currently have a traditional boiler system, with the boiler and cold water tank in the loft; the hot water tank is in an airing cupboard in a bedroom. We want to replace it with a new combi boiler, to be located in the kitchen. Apologies that I don’t have a floor plan to share.
Three companies have been round and given a quote. I found three highly rated companies via Checkatrade; they all have great reviews. I’m leaning towards one company, simply because they’ve given the most detail in the quote. They’ve given the following quote for £6500, including VAT.

Edit 1 - Additional info for comparison. Another company quoted me £5400, but the quote wasn't as comprehensive. It excluded additionals like magnacleanse etc. Another company quoted me £7800, although they were more of a professional firm.
