This is my first post so i apologise up front.

Welcome to the group!

(No need to apologies, you have not done anything wrong yet! ;-)

My parents live in a 1960 detatched house, they intend to replace the
central heating boiler (Glow worm hideaway circa 1982) with either a
combi or a condensing boiler.

All boilers you can install these days will be condensing. A combi is
one that heats the domestic hot water directly (usually) without any
storage cylinder. (for the pedants there are some hybrid combis that
include stored water all inside one box as well)

They have been in touch with BG and got a date for one of there
engineers to come round and access the best option for them.

"Them" being BG no doubt... ;-)

I read with some concern that they need to powerflsh the system
initially at a cost i hear of up to ｣1k,

Flushing (power or otherwise) is probably well worth doing. However
there is no need for it to cost anything like that much (even from BG
who are well known for charging twice to three times what anyone else
would charge).

then replace the boiler. My
parents want the TRV's and controller relacing as well.
Any ideas of cost we should be looking at? (The system presently has 10
radiators).

You could be looking at anything from about £1500 upwards. BG will no
doubt come in nearer £3K!

Should we wait and see what they quote and then get the local heating
firm to come in as well ??

No, get the local firm in now as well - no point in waiting. That way
you should have a few quotes to compare.
