can transfer of supply be stopped if accepted?

Therefore you get a very large final elec bill. Could that stop your gas transfer?

No - for two reasons
The first is that an electricity debt cannot stop a gas transfer (or vice versa) - they are treated entirely separately.
The second (if for example there was an electricity bill 9 days before an electricity transfer) is that suppliers can only object to a debt more than 28 days old.

Roughly the time line goes like this.
You agree to swap, then have 2 weeks 'cooling off' period when you can change your mind. (this may not be applicable to online signups)
Once that time is up your chosen supplier tells 'the industry', who firstly check that no other supplier has already begun the process in the last 28 days. If they have, the second application is rejected, although the supplier can try again under the original authorisation.
If it is not rejected 'the industry' then informs the current supplier who have 5/7 days to object (electricity/gas). This is the start of the final 28 days.
There are limited reasons a supplier can object and the most common one is a debt. If they object there is a short window when the two suppliers and the customer can resolve the objection and continue. Again, the new supplier can re-apply under the same authorisation.
Once the 5/7 days are over with no objection the swap can't be stopped.

See my 3 word edit. If the losing supplier does not accept the transfer reading, the suppliers will agree amongst themselves, not with you. It is not a question of "disbelieving" you in a way which a meter reader or photograph would address, it is the apportioning of the usage which is agreed between suppliers. There is an industry agreed process to follow.

Anyway given that the (actual) reading is larger than the last estimated reading it is very unlikely the losing supplier will challenge the transfer reading.

So how I ensure they use the right reading?

I don't think you can. The only "right reading" is the (same) reading that appears on both the losing supplier's final bill and the gaining suppliers opening bill.

*Normally* it will be the reading you provided but in certain circumstances it might be a reading agreed between the suppliers. There is an industry procedure to cover that but I am not sure if you have a right of appeal. And having failed to correct previous estimated readings you don't don't exactly have a convincing argument.

Anyway presumably the previous supplier's rates were lower. Why wouldn't you want to pay for more units at the lower rate? Had it been the other way round possibly I could have seen your point.
