New Internal Door

The short answer is almost certainly no.

Even if you were technically required to do so, most people would advise you not to bother. And if you were reinstating a door that once existed, it could be considered a repair.

For those that really are bothered, possible areas of concern might be Part B (fire protection and means of escape - the addition of a door generally improving things rather than v.v.), Part F (ventilation - though older houses usually have more than adequate ventilation) and Part J (combustion appliances - and adequate ventilation to those I would take seriously).

Many thanks for your quick reply. Looking at the passageway I think i

is highly likely that there was a door at one time so I will just b putting it back. Ventilation isn't a problem, draughts, now that's different case !

Thanks aga> The short answer is almost certainly no.
