Being quoted £300 to repair these sills on my car. Just wanted to see ask if I'm being ripped off or not?

Next time pop rivet a patch on it and cover it in gaffer tape.
Legally the tester can't remove the tape to investigate, and his bodger won't go through.

Know anyone with a welder nearby?
 
Would going to a body shop repair place be the same as going to a scrap yard?
A body shop should be quoting to do a proper job. If you are just after a plate welded, try local exhaust shops, back street garages etc. I assume the car isn't sentimental and you aren't wanting something special.

£300 is a lot for 30 minutes work.

I'll keep that in mind as the other side of the sill looks like it could eventually go the same way, I don't know any welders unfortunately, it's why I came to this forum for advice!

The car is not sentimental really, it's an old beat up car that just needs to pass the MOT, so I'm not bothered about the body work looking spectacular or anything. To pass the MOT does it essentially just need the hole filled in? I think if a body shop qoutes me £150ish I'll take it, would rather it was welded and not have to deal with it in the foreseeable future.
 
Does that include cutting out the old metal and painting the new? If so, good price.
No, it’s includes tapping the hole to find sound metal and welding the smallest patch possible. Should really treat the rust and patch over. A garage will only patch to pass mot. A body shop will repair to as it was out the factory, I use that term loosely the end result depends on how much you are happy to pay

What the op thinks will happen:
Hammer out all the rotten metal, fully rebuild the sill with reinforced stainless steel and full weld, prime and spray to match the original red paint.

What will happen:
tack weld a metal plate over it and spray it satin black in under 5 minutes

£300 please and it's passed the MOT sir
 
read MOT rules


if the tester can see it hasn't be repaired correctly can still be failed,
looks like it is within 30cm of a suspension mount point.
I had one that just passed mot but as soon as I put it on the ramp, got the wheels off the ground to check it’s on safe it dropped. Some fool had stuck it on with silicone and painted over it. It was a good effort as they made it look like stacked pennys. It was right over the jacking point too

So how can I avoid the latter? Who will should I go to so I can get this fully repaired for the best price? Scrap yard or a body repair place?

A body shop and then the scrap yard when you realise a proper repair will probably be more than the car is worth.

Have you had a look to see what the car is worth? If it's £500 and a repair is £300, it's pretty much going on the uneconomical side of repairing. You might as well use that £300 to put towards buying another car.

:) dont sugar coat it lol.
in the old days would have just ground it back over plated it and undersealed it... have a look around your local fb groups bet theres someone on there whose mate would patch it for a few drinks.

Not sure how good you are at DIY but this repair cost me less than £200. Although I did it myself.

Cheap tig welder plus mask was around £160
Materials £40

Several hours watching youtube vids and practicing achieved this.

I had to do both sides and strip the interior to weld it. Would have easily been £1000+ to get that done. Was my first time welding. I am a lot better at it now! Would have been uneconomical to repair in a garage but had just put £600 into it to replace all there worn suspension.
