EMF

I assume here we are talking about the 50Hz mains frequency and not RF emissions from nearby transmitters or radio equipment in the house ?

Do you know where in the building the fields are highest, and what is causing them ?

Is the problem Magnetic fields or electrical ? the cure is very different..

Do you know the magnitude of the field strengths involved ? 'high' is not a unit -

expect (and if anyone is paying for a survey, insist.. )

electric E fields is measured in volts per metre and

magnetic fields (B) in Tesla, or on old test gear sometime Gauss (10,000 gauss == 1T ),

or possibly expressed as  an equivalent H field (normally proportional to B as it represents the electric current that makes that B field) in amps per metre. 

Magnetic fields are caused when 'flow' and 'return' currents are not in close proximity and form a funny shaped loop with the victim more or less within or very near it - some solar panel layouts, and lighting circuits wired in singles can be very bad for this. A re-layout is the solution.

Electric fields are generated between conductors that are at different voltages and widely spaced. (one of the conductors may be ground) If the sources cannot be re-routed, then some sort of mesh cage may help, and this is where conductive fabrics are sometimes recommended, but in practice it is very hard to make that work.

The short answer to your question is 'yes' but there is a lot of homework for you to understand the problem, before you get to that stage. Also if the sources are under your control i,e, the discomfort goes off with the house power, then it is a lot easier to narrow things down.

If it is from the mains, there are a few things that are known to make things worse...

1. "spider" wiring - typically done on domestic lighting circuits up to the 1980s/1990s - where sheathed single core (or single +c.p.c.) cabling was used - with L looping at the switches and N looping at the lights. In theory it can be arranged so things balance in close proximity (as if it has been run in conduit) but in practice each cable  tended to take the shortest most convenient work and balancing was negligible.

2. Ring circuits - in theory L & N currents should balance in each leg, but in practice small differences in resistance between legs, can create loops over quite a large area. Broken conductors in a ring can make the situations a lot worse, and can go unnoticed.

3. Unscreened cables - using shielded cables - e.g. FP or BS 8436 cables that have an earthed aluminium tube surrounding the live conductors - can help a bit.

4. Diverted PEN currents flowing through extraneous-condutive-parts - most likely in muti-occupancy steel framed buildings with multiple PME supplies, but can happen elsewhere too.

Yes 50HZ mains cables 

the owner has said the kitchen lights flicker quite a bit im going to go friday to test the installation and go from there 

Never heard such nonsense!

Presumably, she can live else there would no longer be a problem.

What are the symptoms please?
