I passed my driving test in 1974 on a Bristol Lodekka bus (16 tons with a load, No power steering, crash gearbox).
I recently had to renew my driving licence at 70 and, rather than spend a fortune on medical and eye tests (every 3 years),opted to give up the higher entitlements.
As far as I am aware I can only drive vehicles with a total GTW (gross train weight) of 3500 kg. OK with my Octavia & Troll.
As for privately rented vehicles of any kind. I found great difficulty hiring even a small van when we moved house due to being over 70. Hirers seem to think you suddenly become senile over that age.

From the AgeUK website...
How do I renew my driving licence after 70?
Once you reach the age of 70, your licence expires, but this doesn't automatically mean you have to stop driving. You just need to renew your driving licence if you want to continue. You'll need to renew it every 3 years after that. Renewal is free of charge.

Don’t forget to apply for any categories of vehicle covered on your old licence, if you still want to be able to drive them after you renew your licence. If you don’t apply for any categories previously covered, you’ll only be able to drive a car in future.

From DVLA "View your driving licence" on querying my licence entitlement:

"Category B, Start date before 23 OCT 1976

Description

You can drive vehicles up to 3,500kg Maximum Authorised Mass (MAM) with up to 8 passenger seats and a driver (with a trailer up to 750kg). You can also tow heavier trailers if the total weight of vehicle and trailer isn’t more than 3,500kg MAM. Physically disabled drivers with provisional category B entitlement will also have provisional entitlement to ride category A1 or A motor tricycles. Able-bodied drivers can no longer ride motor tricycles with a provisional category B licence

Category BE, Start date before 23 OCT 1976


Description

You can drive vehicles up to 3,500kg Maximum Authorised Mass (MAM) with up to 8 passenger seats and a driver with a trailer weighing up to 3,500kg"

I passed my car test in AUG 1964 and re-licenced at 70 in 2017.
So I think to answer your original question the BE trailer weight limit is determined by your driving test date.
Anyone out there with a 70+ re-licence and a driving test post 23OCT 1976?

I have just spent a few weeks swapping my French licence for a UK licence, 2 applications as the first one was lost ( sent Royal Mail signed for but never signed for??) the 2nd one was all copies but they accepted them and sent my new licence, my French licence did not have an expiry date on. I hate paperwork

Neil wants to know how you went about it, a form from the helpful Post Office or online as no doubt he ought to be getting on with it if you have.

Thanks for that Roger, Neil says "bigger than what, everything is bigger than an Eriba". Suppose he better wait for his reminder letter, can't be far away, he's not much younger than you.

Just had to pay 20 pounds for my new 3 year licence . They asked me to return my previous licence cut in half , which I did . After 2 weeks I phoned and said that I hadn't received my new licence, was told it could take up to three weeks to arrive . Forgot about licence for about 2 months , then remembered phoned again explained that I still hadn't received it . Was then told that it had been booked as a lost licence and if I wanted it back it would cost me 20 pounds . Be warned . How do you complain about a government department ?

You Don't, They lost my French Licence so I sent a photocopy of everything with a new application, they sent me my 70+ licence within days, they then sent me a letter to say that my licence was delayed as they had to check with France????????? and then I get an email asking if I had already got my new licence, "yes thank you" says I !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I passed my driving test after 1997, so only have B on my license. This means the hubby and I have to get the E part added by doing a towing course and exam before picking up our new Troll in May.
I’ve been told I can get an English speaking examiner here in NL, fortunately. Hope I can get an English speaking instructor too. There’s nothing worse than struggling to find the right words when you’re already stressed.
