So, the plumber forgot to connect the white plastic condensate pipe to the sink trap. The pipe looks about 22mm or so, judging by eye. The sort that you normally connect up with solvent fittings.
The sink trap has a washing machine/dishwasher drain connection available. So, I just need a flexible bit of pipe to connect the two. Any idea what I should be looking for, please?
Sorry to ask such a basic question, but I don't usually deal with this sort of pipe.
Well, there's no pressure to seal so I would look for a pragmatic solution. Find something which fits conveniently on the sink trap connection, e.g. a bit of flexible waste hose, get an extension hose from a hardware shop if you don't have a spare. That will probably fit inside the condensate pipe. Wrap a few turns of sticky pvc tape ("electrical" tape) around the flexible so that it fits into the condensate pipe reasonably securely, then use more pvc tape over the outside to make a seal between the two. If you apply pvc tape with a little bit of tension on a dry plastic surface you can make a connection which is both secure and tidy looking.
I think the answer to your problem is best summed up by a scene from Matt Smith's first episode as Doctor Who:
637 00:50:41,960 --> 00:50:46,440 The bill. Oi, I didn't say you could go! 641 00:50:56,680 --> 00:50:59,400 Did you think no-one was watching? 642 00:50:59,400 --> 00:51:01,440 You lot, back here. Now!(Of course you could include lines 638, 639 and 640 if you really want to but I don't think that Earth-plumbers are bound by Article 57 of the Shadow Proclamation.)

I bought a length of clear poly tubing to couple my boiler to the
22mm (or 21.5mm) waste pipe. This was partly so I could see if it was producing condensate, and partly because servicing requires disconnecting it at the boiler end to remove and clean the internal U-trap. It was a tight push fit over the overflow pipe. I think I got it from B&Q from their cut lengths section, but that was 11 years ago. I don't know if B&Q still do it, but an aquarium/pond shop would be another option. Tubing of this size isn't cheap, but I could buy just half a metre.At the other end, I have a T'ed into the 32mm basin runaway, with a 32-22 reducer. The basin U-trap has an integral AAV to prevent the basin emptying from sucking the boiler's U-trap empty.
Forgot? What else did they forget: to complete the benchmark certificate which includes a declaration that the condensate drain has been installed in accordance with the manufacturer's instructions (and which will have to be done for the manufacturer's warranty to be valid) perhaps? To notify the installation to building control via Gas Safe Register? To get themself Gas Safe registered? To get trained and competent in gas work?!
Have you asked them to come back and fix it? If not why not? If you have, why have they not been round PDQ and mucho apologetically to sort it?
Did you know you can ask Gas Safe Register to inspect any work done by an installer? For free.
