Intermittant high water level in downstairs toilet

[Old UKPF 106753]

In the last few days we've had high water level in downstairs toilet.
The first few flushes are good and waste flows away but eventually the water level rises in the pan to perhaps half the height of the pan and takes some hours to drain away.
Last night I poured 6 large buckets of hot water with washing up liquid into the pan. They all flowed away very fast with lots of gurgling. It seems to be that if the water was poured directly into central lowest part of the pan the hot water just disappears like there is no obstruction. If poured to the side of the pan the water disappears more slowly and seems more likely to cause a high water level, (but this may be madness on my part 🙂 ).

When left overnight it drains away to the normal level. It then takes 6 or 7 flushes before the water level starts to rise to half the height of the pan again.

I've tried a sink plunger but its really too small and just pushes air around the u bend. We've ordered a R. SIGA 2 Way Rubber Toilet Plunger, Aluminium Handle and Faithfull Tools FAIPDRWCAUG Deluxe Toilet Auger - Clear off Amazon in the hope these tools may provide a fix.

I would welcome any suggestions as to what may be wrong and what has to be done to correct this.

Very many thanks to all.​

You have a partial blockage further down the pipe, it's unlikely a plunger will move it.

Call a better company. Partial blockage

They are DIYing this job I believe, Riley. No company involved yet.

I love how one letter can change something so much. No worries!

Thanks to Riley and Stigster and Snowhead for their helpful replies and funny typos.
Would one of the much longer auger thingys be likely to clear it?
Would we need to disconnect the toilet from the waste pipe to use one of the much longer auger thingys?
Would a jetting company need to disconnect the toilet from the waste pipe?

This does not sound like its within the realms of DIY TBH. Hell even I don't do poo 😱😕🙁
My experience is to call someone with all the gear to see if they can dislodge whatever your issue is. Sometimes they can do it from downstream so don't have to remove, others it's a remove. No rule of thumb I'm afraid.
Have fun 😉

It will depend solely on where the obstruction is

You'll need a set of rods at least. Suggest Bailey locking type for diy. Start by lifting the manhole covers outside. Find blockage and apply elbow grease. It's dangerous and dirty and somewhat likely not to work. Watch out for rats and if it's a cast lid don't drop it down the hole. 😱😵
Lots of youtubes available.

Dont bother with any fancy stuff, go get a traditional mop
not the j cloth ones, make sure shaft is secure wet the mop head, close your mouth and pump away at bog using plenty of water. The hydraulic pressure you will generate is amazing ...Rob Foster centralheatking

Huge thanks to all who replied here. Its been very helpful. Just to let you know the outcome. As many of you suggested, the blockage was a long way downstream. Wessex Water arrived with some big jetting and rodding equipment and found the blockage by opening all the drain covers until the found the first one that was not full, then using their equipment from that drain, they unblocked it. Yayyyyyyyyyyy.
