Property Survey suggesting there's leakage to the sanitary fittings/plumbing

[MrsYip]

Hi,
We just received the survey report. A major issue is damp staining and high damp meter readings in the bathroom, which may be caused by a leak to the sanitary fittings/plumbing.
Should I ask a license plumber to further investigate the reasons? The issue would be more serious if it's due to leakage from neighbouring flats (it's an apartment) or the plumbs inside. If it's due to sanitary fitting or external plumb, it may be not that worse as I am also considering to renovate the bathroom. May I get some advice? Any idea on how much a licensed plumber would check for the checking? Or any recommendation on a good plumber?
The report also mentioned about high damp meter readings in the hallway and in the bedroom around the patio door, which also worries me.
Normally, how should we negotiate this issue with the seller? Shall we ask him to bear the cost of fixing it? I believe it's unlikely though
Any advice or sharing of experience would be very helpful.
Thank you.

how old is the house?

do you think the bathroom is original or a later refit or addon?

do any of the pipes (especially soil pipe) come up through a concrete floor?

repairing leaky plumbing is one of the easiest ways to cure damp.

Replumbing a bathroom may cost a few thousand if you want to spend it, but it a minor maintenance or update job when you think of the cost of a house. It may need doing every ten or twenty years.

It is very common for a housebuyer to rip out the old bathroom because they don't like it and it is old fashioned.

You can buy a bathroom suite for £500 but whatever, you need a good plumber. Quality taps and accessories make the difference.

Thanks for your sharing. It's an apartment built in 2004. The bathroom is original. The property has been rented out for a long time.
My worries are the leakage is from the neighboring flat. no sure if it could be fixed easily.
May I ask if there are any sources I could locate a good plumber to assess the seriousness of the issue?
Also, any suggestions on where to get a bathroom suite?

If you are in UK, there are sure to be local bathroom shops catering for all pockets. Find the ones that builders and developers use. They will be on shabby industrial estates or down back streets.

Have a look in Wickes first. You may be surprised that they have modern ranges of accessories sold under a different name.

White porcelain looks much the same whatever you pay for it. But buy a WC made by a long-established British maker.

Glossy showrooms are obliged to charge enough to pay for the owner's Jag and his wife's Range Rover. If money is no object, use one.

Try to find a local plumber by personal recommendation from someone you know and trust, and who is capable of recognising a good job. Avoid advertising websites where the trader pays to be listed, especially if they masquerade as "trusted" or "rated" recommendation websites.

Thanks! I am new to the UK and do not know many people yet, so could not get recommendations on local plumbers . I have been try asking in the local Facebook group but not much feedback so far.
If there is any recommended plumber in Reading, please let me know. Thank you.

Go to the local plumbers merchant and ask them who they would recommend.
