Being the not-so-proud owner of two of these treasures (should be taken away and buried on a remote island), the Keston Celsius 25 can be installed with very long flues. Please confirm that you don't have any special flue requirements.
The boiler Will be getting moved to an outside wall so flue length isn't an issue.

The next question would then be what is the annual gas consumption? The Keston Celsius 25 has a pretty efficient heat exchanger but the controls are too simple.
My consumption is about 50,000 kWh/annum for just the boilers. I am thinking of a Veissmann Vitodens 200W 4-pipe system boiler with Lambda control and weather compensation. At up to 108% Hi efficiency, it could save maybe £200/annum compared to my Kestons.
