Thanks Tony.
I'm going to clean out the radiator this weekend. Can only help matters I guess.
A gas engineer replaced the sensor. He spent 30 seconds on the boiler and didn't fill me with much confidence anyway. Rest of the time was on an iPad 'filling stuff in'.
Appreciate the help and will...
The radiators were changed as they looked old and I wanted new ones.
Water was brown when they were drained with thick sludge at the bottom.
Some sort of thermostatic sensor on the boiler was changed I believe.
I'm wondering if most the sludge in the system has settled to the lower radiators...
Update.
A stat sensor has been replaced.
Not sure it's done the trick if I'm honest, but the cycles aren't as frequent. (Only replaced today)

Hot water works fine.
Boiler cycles on and off for central heating. (Not all the time)

Yeah I was thinking PCB. I have fitted a smart thermostat onto it before aswell, since took it off and swapped between normal thermostat and smart. Yesterday I seemed to have little issues with smart thermostat on (had problems with it installed before). However went back to older wall...
doing my head in now.
1 day is fine next day isn't.
1 hour is fine next hour isn't.
The problem differs and is never consistent.
The main problem is the boiler keeps cycling on/off. Sometimes ignites sometimes doesn't.
Them when thermostat is on will continuously go on and off. Then...
I'm having the exact same problem, boiler keeps firing up 24/7 for about 3 seconds. keep trying to blame my 'newish' smart thermostat. but that seems to be working as normal with scheduled heating settings. Has anyone found a solution for this yet? driving me insane! actual boiler temperature...
I know this post is Abit out dated but hopefully someone can help, I'm installing a new kitchen and my cooker hood is going to be butted up to the wall units, the designer in b&q said 'as I'm not leaving a 50mm gap either side the minimum gap from the worktop to the underside of the wall...
