Well make sure he sets it at the correct level as recommended by ALDE as some on here have been given conflicting advice by their engineers.
Hi clive that not the only thing, i want the gas engineer to look at the radiators they are hot at the bottom but cold at the top so I think there trapped air so I think he have to bleed the system thanks for your help in this matter

Bleeding is quite easy just like you do at home. After bleeding don’t forget to check the fluid level and top up as required.

What is a simple task to some people, is not easy for others.
Identifying where all of them are located I found quite a challenge, adding to this access needed some disassembling of the furniture, admittedly that was doable.
It was finding the info of what was fitted and where seemed unavailable to us customers, probably so the trade gained any required rework.

I noted more recently the "trade" now simply blasts the fluid round* so it purged the bulk of the air with it, rather than the DIYer just having to use the gravity of the header and physically bleeding the bleeders.

* using a temporary pump system.
