Can anyone offer any help or advice please? Lay person with no building knowledge!

For a month now we have had water seeping through our kitchen floor where it joins with a conservatory extension.

Initially it was a little pool that we could wipe with a tea towel. Recently its around 60 litres daily.
Always during the day never at night.

We've had 4 plumbers and two drain specialists inspect our downstairs with varying diagnoses. The water comes from the party wall side of our semidetached house where there are no water or drainage pipes. All manholes and drains are apparently working well and clean as a whistle.

We think we had a eureka moment yesterday when a mains plumbing specialist, poked around a drain under a downpipe next door over their fence.
The drain is a swamp of vegetation, grass, rubbish and there seems to be a film of detergent/drain cleaners over the top. The smell from this swamp is the same nasty odour coming through your floor and behind our kitchen cabinets.

We spoke to next doors Tennants and asked them to pop on their washing machine and low and behold 20 minutes after they did. Soapy water was flooding in our kitchen. Around 40 litres total.

It has been going on for a month now and out kitchen floor, now hall is totally saturated lifting all laminate tiles.

The issue is the landlord of the house next door doesn't agree that there is a problem on his side. He denies there is an issue with his drain saying its been inspected by a plumber and it drains ok.
Obviously we can't access his property without his permission or undergo any drain exploration. But the flooding is seriously ruining our house.
If there is an issue our side we have insurance that covers repairs but we can't diagnose the problem without getting down his drain.

Any advise on how to handle this and what to expect to expect in terms of repairs when the leak finally stops. Im some areas of our kitchen the water is moving up the walls.
 
You would need to hire a qualified surveyor to decide what the problem is and who is responsible for fixing it. You would need the owners agreement for this and if unreasonably withheld then mediation maybe might be the next move.
 
Unfortunately the amount of water is increasing evey day. Were now currently mopping up two inches of water from the floor and its pouring through a hole in our wall
 
The fastest way would be to make a claim of statutory nuisance against the landlord, under s79 EPA 1990.

Complain to your council's environmental protection department, they will investigate and serve an abatement notice giving the landlord 21 days to remedy the situation or face prosecution.

You could make a private claim if the council can't react quickly.

Also try your water authority, as they have powers to require this to the rectified.

You may need a professional report, a brief one will suffice, to support your claim.

Advise the tenant and landlord you will be pursuing them for your costs, which will be in addition to theirs.
 
Thanks for your advice.
Weve been allowed access to their garden and drain tiday after msnynpleadimg phone calls. His drain is blocked and overflowing into an old drain under our kitchen floor which was where the our old sink was. We've been mopping up their washing machine and kitchen sink waste. Fortunately the nextdoor landlord seems to not care about us traipsing in his garden or digging up his drain as long as we pay for it.

Now you have found the cause can you dig in your own garden and block off the old drain on your side.
 
We can. We've finally lucked out and got a really motivated drain guy who is on the case thankfully. Don't know what will happen to the next door drain water but at this stage we don't really care. In a hotel and loving being in a dry environment. Thanks for you input. Really appreciate it
