Found them online. It looked like a straight forward hassle-free fee agreed in advance service. When they book you in you can't know who you are booked with or contact them prior to your appointment, which is odd if you want to discuss details in advance. Then the selected conveyance contacts you and you have to sign a further agreement, different to the original one with iMyHome. I provided our conveyance all the required details for our valuation, which he chose to ignore. He also ignore all our conversations on the day and went onto over value our property (HTB repayment). I had to complaint to iMyHome who washed their hands and said it was between us and the conveyance. After much pushing our valuation went down and went through without issues with HTB. I am very unhappy as this is not people who do a good job, they just tick boxes, paper push and play it safe for them but at no point they are trying to impartially do a figure, instead they do what they know it will give them "no hassle" at your detriment. I had to do most of the work and then pay for it. TBH this is an industry issue and not particular to iMyHome and I guess my bad for expecting better.
