For an Intermediate Instrument Rating appropropriate to the knowledge, experience and skill of a relatively inexperienced instrument pilot, it is only reasonable that the privileges of that rating should be commensurate.
Put simply, all such pilots probably require is a rating which entitles them to fly an aircraft under IFR and in IMC in departure, en route and arrival phases of flight in airspace approved for such use by national airspace authorities. Theoretical knowledge, language proficiency, medical requirements, flight training and testing should be proportionate for a rating which would require a 600ft cloudbase and 1800m visibility for take-off, landing and at an alternate with approach minima no lower than 'full IR minima' +200ft for precision and +250ft for non-precision approaches.
Alternatively, spend thousand of pounds more and obtain the 'full' IR, whose full privileges you will probably never need.
