as new ly installed boilers now have to have a SEDBUK rating A or B - and these are condensing type boilers: does it mean that if replacing a boiler (eg my potterton flamingo-i have to get a condensing type? and these condensing type boilers are system boilers that have the pump, etc built in? so is pump removal/pipework changes required also? this seems unfair!!!!
new boilers SEDBUK rating A or B? all system types?

You can buy regular versions of condensing boilers too. Changes in pipework will still be necessary if you have a gravity HW circuit as well as other additions to meet Part L. Most of these requirements were in place before the A/B bands became mandatory.
You can buy OV system (open vent) condensing boilers. Has no pump or pressure vessel internally but is is not a lot cheaper than the sealed system version; demand is so low. Sealed system are a lot easier to bleed and less likely to sludge up.
As an aside you start by asking a question then collapse into a whine without the answer to the question.
