1 135
2 150
3 135
4 140

got it the other day was about £20 i could take it to work and check it against a calibrated pressure gage.

worth getting it checked, have seen a few testers giving low readings.

Think compression should be between 180-200 on clio

I have also noticed that if get about 3000 rpm and give it full throttle i get a bit of a rattle which makes me think valves but i dont know if they all have a rattle in that scenario

Standard good compression is about 190. But all your results are within 10% of each other which would suggest if it is down on power it could be due to cam timing.
Cheap compression gauges sometimes dont give true results, though. If they're all even (which yours are) and you've no other symptoms it could be fine.
