Should I pay for remedial work?

A few weeks ago we got a plumber to install and commission a manifold for some underfloor heating.

They came and did an estimate, we accepted, they did the work, an invoice came, we paid.

So far, so good.

Then we noticed that sometimes when it was running it tripped two circuits on the consumer board. They came and resolved this - they had attached the new manifold to an existing socket ring main and by moving it to the same circuit as the boiler the problem was resolved (their specialist electrician was contacted and told the plumber/electrician on site this was likely the issue as we had a newer consumer unit).

Then we noticed some of the loops weren't getting warm, and they came and vented the manifold and that problem was resolved.

So far, still so good really - they accepted the issues I raised and came to fix them in a reasonable time and at no extra charge.

Finally, we noticed that the socket circuit they had originally used to connect the manifold was no longer live (as some point, don't know when, they'd cut the wrong wire).

So we rang and they came out to fix it; and because they'd cut the cables right back they had to put a hole in the wall to reconnect it (a newly plastered and painted wall...). He made a reasonable job of putting the square of plasterboard back in the hole, but it'll still need filled, sanded and painted.

All good(ish), until they sent an invoice for the last visit! (a little under £200)

I e-mailed to complain, but I think I'm getting a call tomorrow explaining why I should pay...

What should I do?

Wait for their explanation.

Wait for the explanation, but I have difficulty coming up with a valid reason for them charging you for correcting what was entirely their series of errors.
