Rip out the immersion heater and NSH's (if that is what they are), switch from E7 to single rate, and, hey presto, you've instantly trebled the cost of your heating and hot water overnight!
If you've really 'no idea', why not check before you start work?

Thank you for unhelpful opinion! Really was useless and answers nothing .

My so has recently bought a 1 bedroom flat. There is no gas only electric . We have taken the old copper boiler out to install a more cost savings efficient one . We also plan to replace the old electric radiators for more  energy efficient ones . The boiler only has to supply hot water to the kitchen sink And bathroom sink there is an electric shower . Was hoping someone can advise on on cost effective and energy saving boiler /size/ 3kw ? 30 ltr ? and radiators ? We really have no idea . 

Many thanks 

By copper boiler, do you mean water tank with an immersion element (or two) in it?  In which case the only upgrade possible is really an insulated tank.  But are you saying you started without knowing what you were going to replace it with?  

Does the flat have Economy 7?

Yes it was an Immersion with a pump that does not work there was a bath there previously but only a shower there now

Had you kept the old tank, possibly on an off peak tariff and used the hotwater from it you would have been able to have a tank full of hot water to wash and shower with at less than 10p/kwh. Now you've replaced it with an electric shower it will cost you whatever peak rate your electricity costs, likewise with the electric flow boiler you are paying at least twice as much to use it.

You really need to understand what sort of heaters you've got - storage heaters on E7 or just wall mounted convectors because storage heaters use off-peak cheaper rate leccy whereas anything else whether it be a £10 fan heat or £1000 Fischer/Rointe or any other exotic heater will use peak rate leccy.

I fear that you've gone about it the wrong way and it could cost you a lot more than you bargained for

Prob not explained this very well but we have had some advice on the basics which I didn think I needed to mention .

Perhaps explaining what you still have and what you want, and what advice you have been given would help?

It's not unhelpful to warn that changing from an immersion heater plus NSHs that run on (relatively) cheap E7 rate to an electric boiler and panel or convector heaters that run on single rate would be a big expensive mistake.  On the contrary, it's a very useful answer because it will save you money, but only if you heed it.

It will also help other forumites who might be about to make the same expensive mistakes that you have.  It's not just about you.

OP, it was not an 'opinion', it was a statement of fact. Your costs will treble. 
This is assuming that you do have E7 and NSH's, which you still haven't confirmed. 
How do you expect to get helpful advice if you don't give us the basic info?
What is baffling all of us is why you would remove the existing (working) immersion heater without first knowing what you will replace it with?
What is this 'pump' you refer to? Immersion heaters are gravity fed, the only reason for a pump would be perhaps to feed a power shower installed over the original bath?

It appears that the toys have now been flung. The OP did not like any of the advice or suggestions or any help in trying to get a working solution that would be cost effective. 

But perhaps "Deleted User" will come back in future. Under a shiny new user name, to ask advice on why her sons electric bills are  so eye watering high?

Unfortunate.

Hi, highly recommend the agile octopus tarrif for electric only home as works really well rate wise.
That should save at least 30% on your bill without any replacement boilers.
So far this year since Feb my average rate is 8.6 pence per unit.
Load on these forums about it and well worth a look.
The only downside is high price between 4pm and 7pm but if you can turn heating off for those 3 hours and run as normal for the rest you will save a small fortune.
