My wife is registered deaf but can still use a phone. We've been through the same kind of process of searching for a solution. All the loud ringer products that are powered from the phone socket are fixed devices. i.e. they make the phone's ring louder, but only when plugged in to a telephone socket. They aren't portable.
We went through a phase of trying a wireless door chime with a flasher unit. This was portable. I'm telling you this because of the parallel with what you're looking for. The problems with it were two-fold. First, in order to be always ready, it had to maintain a live wireless connection permanently. That ate batteries like nobodies business. The second problem was having to remember to take the chime with her every time she moved rooms. It wasn't that practical when doing housework. The upshot was it cost a fortune in batteries (ordinary and then rechargeables + charger) for something that often got left in the wrong room when someone actually called at the door.
Wireless ringer extensions do exist in the US market.
LINK I'm sure if you search on Google you may well find a UK licensed equivalent. The problem though is cost and practicality. Even with a wireless ringer, you still have to get to the phone in the other part of the house. Second, a twin pack DECT cordless phone kit is likely to be cheaper and you can answer the call straight away. That's what we (my deaf wife and I) use. It works. Simple.
