I mean I think it's not that big of a deal because we already fit 92% boilers ,
As far as the 4 options weather comp , Load comp , flue gas recovery or smart control yada yada yada lol... I mean I always offer some of them anyway . Example I fit many boikers like vogues with weather comp I mean the sensor is only £25 and smart controls are be coming more popular and wanted especially with phone apps etc. I always give my customers good but simple controls as many of them can be too technical for less technical customers but as far as prices go there's not huge huge amounts in it ... especially if heating systems are understood and set up properly by the installer which in turns allow the sensors and controls to save that £ ...
