The restrictions around conducting viewings in Wales have now been lifted entirely. This means viewing of occupied property is now allowed (previously it was unoccupied dwellings only).
Hat tip to Howard, one of our subscribers for the update.
The first confirmation can be found in an FAQ on the gov.wales website which was last updated 27 July 2020:
Are there any remaining restrictions on home viewings and other housing market transactions?
The restrictions on viewing occupied properties will be lifted from Monday 27 July and prospective buyers and tenants can now make appropriate arrangements with landlords, agents or property owners to view properties. Everyone involved in the process should follow social distancing and hygiene guidance.
Finally, the regulations which contained the restrictions have now been revoked and have been replaced by The Health Protection (Coronavirus Restrictions) (No. 2) (Wales) Regulations 2020.
From 27 July 2020, it is a “reasonable excuse” to hold a gathering to “undertake activities in connection with the purchase, sale, letting, or rental of residential property“.
At the time of writing (27 July 2020), the primary guidance for this purpose in Wales “Moving home during the coronavirus pandemic: housing sector” has not been updated and still refers to vacant property having been empty for at least 72 hours (or deep cleaned) for viewings. However, this guidance was last updated 24 June 2020 so it would seem to be out of date now.
