Which is all very lovely. But how does one actually access that relief? Almost certainly, unless alternative accommodation is provided by an employer, one will have an 'interest' in another dwelling at that point even if just a lease, which I think will preclude one from accessing this relief. If one is provided with job-related accommodation then one automatically obtains relief for an indefinite period anyway. Does the relief only apply if you aren't living in a dwelling-house - so, say, a yacht or hotel? There is a good example here which pretty much suggests this.(3)For the purposes of [sections 222(5) and 222A and] subsections (1) and (2) above—
(a)a period of absence not exceeding 3 years (or periods of absence which together did not exceed 3 years), and in addition
(b)any period of absence throughout which the individual worked in an employment or office all the duties of which were performed outside the United Kingdom [or lived with a spouse or civil partner who worked in such an employment or office], and in addition
(c)any period of absence not exceeding 4 years (or periods of absence which together did not exceed 4 years) throughout which the individual was prevented from residing in the dwelling-house or part of the dwelling-house in consequence of the situation of his place of work or in consequence of any condition imposed by his employer requiring him to reside elsewhere, being a condition reasonably imposed to secure the effective performance by the employee of his duties, [and in addition,]
[(d)any period of absence not exceeding 4 years (or periods of absence which together did not exceed 4 years) throughout which the individual lived with a spouse or civil partner in respect of whom paragraph (c) applied in respect of that period (or periods),]shall be treated as if in that period of absence the dwelling-house or the part of the dwelling-house [were occupied by the individual as a residence] [if conditions A and B are met.]
