You'll probably find that
BCFT, my former employer, has the cheapest course, at a little under £1500. The reason is that they can use their FNPT2 'simulator' for 2.5 hours of it. Very high fidelity to their aircraft fleet, down to insrument fit (hence they are allowed this concession). The aircraft are Beech 76 Duchesses, as is the sim in fact (the remains of a written-off one, shipped from the US and cut up for realism!). They have at least 3 MEP examiners on staff, probably more, at least one of whom is full-time. All instructors have flown commercially, some still do.
Note all landing fees and VAT are included in their price - check that if you compare it with any other school.
