You must sign a legally binding contract with an estate agent if you use one to sell your home.
You must stick to the terms of the contract or you could be taken to court.
Estate agents must also treat buyers fairly. They must show any offers promptly and in writing to the person selling the house.
Estate agents are also legally obliged to pass on any other offers for the property right up to when contracts are exchanged.
Complain about an estate agent
You must complain to the estate agent first and give them a fair chance to sort out your complaint. If they do not, you can complain to one of the following schemes:
The Property Ombudsman
Property Redress Scheme
Ask the estate agent which scheme they belong to.
