Why does the pressure keep dropping on my combi boiler?

it could be that there is a leak on the heating system pipe work or radiators themselves or from the boiler internally these type of leak would most probably be visible unless the pipe work runs under the floor, it could also be the expansion vessel needs re pressurizing or replacing or the pressure relief valve is at fault these faults can be seen if the prv pipe work that runs to the outside would be dripping or running with water

What is the best combi boiler?

In my professional opinion the best quality boilers on the market are Worcester & Vaillant they offer a great range of boiler types and great warranties, they are competitively priced and the customer service is great, Their spare parts are mostly off-the-shelf items so with regards to repairs they’re relatively a quick turnaround
