Puncture repair

Generally the rule is of the tyre walls are affected then a new trye is required.

Tyre fitters will repair a puncture if it is away from the tyre wall and there is no damage.

OP has stated that it was in the center so it would not be in the wall of the tyre.
Screws don't usually cause a instant  deflation but a slow release of air it may have been in the tyre for sometime you usually discover them by hearing them clicking whilst driving

It's not a scam, you've damaged the tyre by driving with it so flat.

The sidewall isn't designed to flex as much as it will without air in it.
There is no belt in the sidewall to reinforce it, it's just rubber and cord with a rubber liner.

Over flexing it just causes the rubber liner to crumble under the stress and seriously weakens the tyre.

If the puncture is too close to the side wall, a repair is often not effective.  Sounds like a new tyre is needed and you've been given good advice by the garage.

The OP said it was in the centre, i.e. NOT too close to the sidewall. The issue was that the sidewall itself was damaged.

Advice needed. I had a screw in the centre of a fairly new (two month old) tyre. I must've travelled approximately 20 metres before I realised. When I took it to my usual backstreet tyre place they said the same thing as last time. Because it was driven flat it's damaged the inside wall (showed me rubber crumbs) so it'll need a brand new rather than repair. 

Over the years whenever I've had a puncture I've always just head it repaired. Does anyone in the know think this is a scam or just new safety measures most places have to abide with now? 

How did you know about the screw so soon? If realised within seconds the tyre would either have blown or if just a slow puncture would still be at near full pressure. If the tyre never went flat the crumbs are either a scam or a sign the tyre had another problem, if the latter then you may have had a lucky escape. If you suspect the garage is refusing to fix repairable tyres then try elsewhere.

If you realised within 20m then the tyre was completely flat and the sidewall will be compromised. Buy a new tyre!

There's two things getting mixed up.

First is whether the tyre will still hold air. Put a plug in it, yes, it will.

But is that really all you want from your tyre?
Don't you want to be sure that it's still SAFE?
You know that the inside of the tyre has been worn in places it's not designed to wear.
The reinforcing structure has been subject to loads it's not designed for.
Doesn't that bother you?

Is that really only worth a hundred quid to you? Half a penny per mile for the next 20,000 miles or so?

The "crumbs" thing was a new one on me. Which is why I'm asking the question. Previously (same garage) I've had punctures repaired. They've never showed me crumbs etc. Ironically, the tyre they replaced 6 months a go was the same one that had a puncture (screw) in it. I can say categorically I drover it 20 years from outside my house very slowly which is why I heard it straight away and stopped. 

Just wondered if it was a new thing as the last two punctures they've gone on about the crumb and in previous years/decades they've just repaired or replaced if it was in the side.

No. I had a tyre place refuse to repair for that reason around 20 years ago.

Yes, IIRC the relevant British Standard dates from about 1984.

Splitting hairs.  Either way, it's a new tyre.
