A mailshot by Connells-owned online firm Hatched resulted in a complaint to the advertising watchdog.

Hatched’s mailer said:

“Dear Home-owner,

“We’re very sorry to see that your sale has recently fallen through with Haybrook, Swinton, but we wondered if we could help you find a buyer (whilst also saving you £1,000’s in the process?!).”

The complainant objected that the mailing was in breach of the advertising codes as it was not clear that it was a marketing communication, and the claim that the sale had fallen through was misleading.

Haybrook, in Swinton, South Yorkshire, is a part of Spicerhaart.

A spokesperson for the Advertising Standards Authority said: “We contacted the advertiser who agreed to withdraw the letters from their marketing.

“We reminded them that their mailings should be clearly labelled as marketing communications and told them not to repeat those claims in the future.”

Also informally resolved was a complaint about an agent, Hamiltons, which advertised a two-bedroom apartment.

The complainant said that when they went to view the property they discovered the second bedroom was in fact a basement that had the potential to be converted, but as yet there was no building control approval in place.

The agent said the claim had appeared as a result of human error.

A third informally resolved complaint was about an advert for a villa on the website of JV Properties.

The advert said the villa had a barbecue, but the complainant said it did not have one.
