Gas (sulphur) type smell in cellar when it rains


I have a problem with the house I have just bought where whenever is rains, there's a very strong gas type smell in my cellar - quite like sulfur. This smell spreads to the rest of the house and makes you feel nauseous. I have had a drainsman come out who did a CCTV inspection and there's no damage to the drains that should cause any problems. He said because the house has been empty for some time, I should run a hot bath full of bleach once or twice a week then pull the plug to help clean the drains in case this is what is causing the problem. I have tried this but it hasn't solved the problem. I was at the house last night and it was raining slightly outside and the smell was very strong. I have noticed the smell is worse if the rain is quite fine.

I am lost as to where to go now to get this issue sorted. Can anybody point me in the right direction?

Any help would be appreciated.

"it might be an idea to call the gas board to check for leaks, if the house is on a hill or bottom of hill it could be hydrostatic expansion this happens when the water pressure is high or uneven. one thing you could try is using a dehumidifier as it could be something simple as damp rising and when it rains the pressure outside is forcing the moister in, you may need a damp company in to dampproof the basement
there are plenty of companies that specialise in this problem and they often do free surveys"
