Landlords are responsible for the building insurance and also insuring any contents of their own. Failure to inform your insurers that you are letting may invalidate your policies. We can assist with specialist insurance companies who can help to ensure that you have appropriate landlord insurance, please ask for details.
If the landlord is a UK resident, it is entirely their responsibility to inform HM Revenue and Customs (HMRC) of rental income received, and to pay any tax due. However, if the landlord is not resident in the UK during a tenancy and unless an exemption certificate is held, we as landlord's agents are required to retain and forward to HMRC, an amount equal to the basic rate of income tax from rental received, less certain expenses. See http://www.hmrc.gov.uk/cnr/nr_landlords.htm for more information
As the landlord it is your responsibility to pay regular outgoings such as mortgage, service charges, maintenance contracts etc. In most circumstances the tenant will be responsible for council tax, water rates and gas and electricity. During vacant periods these charges will revert to the owner. You may be able to claim a reduction in council tax during periods of vacancy.
