Abuse of Warrant under Right of Entry (Gas and Electricity) Act 1954

[Guest]

In January I obtained a repossession order to evict a tenant from my property for non-payment of rent. The property was actually vacant at the time, the tenant having left without returning the keys. 7 days after gaining possession, SSE entered the property and disconncted the electricity supply. They had a warrant in the name of the tenant, who it appears had run up a large amount of debt. In doing so they ignored the Writ of Possession notices stuck to every door and window on the ground floor of the property. They left no notification of their action and I only found out when a contractor went in the clean the premises. SSE claim that the onus was on me or the tenant to inform them and their action was entirely legal, a view supported by the ombudsman. I cannot accept this. Any advice?
