There's conflicting advice on this BB.
Re Dan D's post at Jan 09 where he says 'Dont go to Dyson - they want a £65 call-out charge plus overpriced parts', the latter is wrong. The £65 charge (now £69 - I have just paid it) includes all parts. This is why we decided to go for this option when we had the same problem. For £69, the fault (a burnt out motor) was repaired (i.e. a new motor installed) and two other parts replaced too (a split hose & a HEPA filter, the latter just because it was old).
In short, I would say Dyson give it what arguably amounts to a service for the £69, with all parts included.
As for the engineer's post saying the cost is/was £79 back in 2004, it isn't now - it is £69.
