Need a big combi boiler

[hammers4spanner]

Right guys .

Customer of mine has 2 combi boilers running a large house . Yearly service carried out by BG and now cust has asked me to quote an upgrade.

Unvented is not an option as current site is utility room and would be not enough space.

So what combi boilers are around that could run a large house with several hotter draw offs .

No worcester high flows either.

I' going to check next week .
I was initially thinking two baxi eco blues but they have asked for possibility of 1 boiler.
Current boilers are two 28 kw icon-t boilers
