Electric Shower Replacement

[Cool_Hand_Luke]

Anyone know how much it should cost to replace the internal part of an electric shower? I've purchased the part - the whole shower engine - so just looking for someone to take out the the existing one, and wire/plumb the new one in. Its a like for like part (hopefully :greengrin), so if anyone on here knows how much this should cost, can recommend anyone, or even qualified to do this themselves and wants to give me a price...then it would be appreciated :agree:

Thanks in advance
