Rajinder Singh Pander from Windsor ignored council orders to demolish the structure, which failed to meet basic housing standards.

Occupants were forced to live in cramped, substandard conditions, raising serious health and safety concerns.

At court, the Judge found the offence to be at the higher end of negligent culpability.

A fine of £14,000 was imposed, reduced from £21,000 to reflect a one-third credit for a guilty plea, alongside £7,547.15 in costs. The total financial penalty imposed was £81,043.88.

Councillor Tom Bruce, the Deputy Leader of Hounslow Council, said “This prosecution continues our clear message that we will not tolerate landlords who put profit before people’s safety. This outbuilding was wholly unsuitable for residential use and should never have been occupied. We always take robust enforcement action against those who choose to flout the law and undermine residents’ safety. If anyone has any concerns about any property in the borough, please report these to us as soon as you can.”
