Hi,
At present in Plymouth we pay £35 for gas safe inspections between every occupancy in our PSL properties. Occupancies typically last between 1 and 6 months, last year we spent over £2.5k on inspections.
Gas Safe inspections must be undertaken atleast once every 12 months according to the Gas Safety (Installation and Use) Regs 1998. Section 226 of the regs recommends that the pipework is tested prior to re-letting although this is not statute.
The mananing agent insist that they have to test during each void, however another local agent has informed me that they don't bother. If there is a gas problem and the property wasn't re-tested prior to letting then the LA can be prosecuted.
