"Depending on what filter
The filter could be up to £100
Inhibitor upto £20
Drain the system, fit the filter and refill the system will be done within an hour on a combi boiler system, so depending on the hourly rate, but up to £100 (mine is £65, but my running costs are relatively low)

So all in, around £200"

"Depends on if you suppling the filter, if there’s already a filter in place, or if system needs draining and pipework needs cutting into. So not a straight price on information given."
