These niche providers are always super expensive. By the time you join you will likely spend £200 as you also need to buy a VDSL router.
In your shoes I would switch provider, and in the process switch to fibre. You do not want metered for fibre in my view:
Prices right now, subject to change: All unlimited usage cap:
TalkTalk - Faster Fibre Broadband - £27.50 including line rental with free setup and free router:
Sky Fibre - £28.88 including line rental with £9.95 setup and free router
BT - Unlimited Infinity: £29.99 including line rental with £59.99 setup and free router. You get a £75 pre-paid master card though, which eats up the setup fee, and mastercard is accepted almost anywhere on the high street.
Having used all 3 providers my best internet was with BT, the best customer support was with Sky.
The process of switching is super easy, assuming you have everything with UNO currently (phone, broadband and line rental). Just give the new provider your phone number as part of the order, and they will inform uno you're leaving and take over automatically. All you need to do is place the order with the new provider, do not cancel your line with UNO, if you cancel with the existing provider there is nothing for the new provider to takeover.
I am guessing you didn't take my advice to go for Infinity over here then?
