EMF cognizant electrician in London area?

It's been a week since we had our new central heating boiler installed. Unfortunately it feels as if it has contaminated the house electrics,as my house now feels practically uninhabitable.I Had British gas out to check the connection but unfortunately the engineer had no idea about EMF or grounding or even dirty electricity. He did take the cover off to check it,which revealed a mass of  wires,circuits, and electronics, which eh informed me, is how all the new boilers are. My old boiler is no longer manufactured, so unfortunately I am stuck with this monster. I have since looked on line and it seems that a few people have had serious sensitivity problems with these new  boilers, with some having to move out of their homnes. SO I am  thinking the next step is to get an electrician in who may be able to carry out  earthing/remedial work. If anyone knows of an electrician in the London area, or an emf knowledgeable electrician per se, I would be grateful.

Thanks
