The Residential Landlords Association has launched a survey among its members into letting agent fees charged to landlords on repairs.

Yesterday evening, it sent around a note saying: “A London landlord has recently challenged one of the country’s biggest agents, Foxtons, over the level of fees charged for replacing a light fitting.

“The landlord was charged £550 (plus £66 VAT). However, he discovered that the maintenance company allegedly charged Foxtons £412.50 and the agency is believed to have added a 33% commission fee to the contractor’s bill.

“If you use an agent to manage your properties, do you know how much ‘commission’ you are being charged?

“How much the contractor is paid by the agent?”

The survey includes question about whether the agent seeks the landlord’s approval of costs before work is carried out, whether they inspect work after it is done, and whether landlords ever see contractors’ invoices.
