The estate agency industry is “asleep at the wheel”, the new owner of Humberts has said.

In a letter to staff from Matt Spence, founder of holiday letting business Natural Retreats, he says that the industry is “festooned in doubt”, with a lack of identity and no true pioneering brand or leader.

He says that the larger brands seem to have no idea how to adapt to changing demographics.

He adds: “It is my view that actually the larger branded agents have a lot to do with the residential market not performing consistently well, yet they are quick to cry into their milk.”

In the letter on Humberts headed paper introducing himself, Spence explains that Natural Retreats bought Humberts out of administration.

Spence himself will be full-time chief executive of Humberts, with Anthony Wild as chief financial officer and Ewan Kearney as chief operating officer. All three hold the same positions at Natural Retreats.

Tim Simmons continues in his role as head of residential sales at Humberts, and Samantha Trott continues as head of HR.

Former boss of Humberts Ian Westerling will be head of new projects. He had actually quit his managing director role in March, but as director returned a month later to oversee the rescue of one of the UK’s oldest estate agency businesses – founded in 1842 –  after backers Mercantile Group withdrew their funding.

Spence says of Humberts and Natural Retreats: “Both businesses have similar traits, and while they will remain entirely separate companies/brands, they will be extremely close.”

He says that Natural Retreats – which operates in the UK, mainland Europe and the US –  has been grown through hard work, determination and a “never give up” attitude. He emphasises: “Great things only happen through innovation.”

He says that Humberts will become the ‘rural champion’ brand.

First, the plan is to stabilise the business (“There’s a lot to do here!”) and then to open other revenue streams, from land agency to property management and lettings.

His letter strongly suggests that anyone currently with Humberts without the appetite for change should get out now.

He says: “I do know that this may scare some or some may scoff  to those that find change unnerving, I give to you a great word –’nervited’.

“This combines nervous and excited (my little girl, Madison, could not say both so this was what she said!).

“Well, I am “nervited” too, so it’s ok! You can’t be brave without being scared. To those that scoff – well this probably isn’t the right place for you . . . change, hard work, a will to never give up on a dream and ambition are not for everyone, and I understand that and that’s ok.

“Companies need all types of people. I know this. Over the last decade I have surrounded myself with people who are far better than me at most things – I am humbled by who I work with and everyday I have to pedal like crazy to keep up –but I promise one thing –  I will work as hard as I can, every day, to make this work for everyone who wants to jump on board and I promise to never give in.

“I would rather fail, than to never try.”

Spence says the combination of a high-end rural estate agency and a premium rural holidays letting agency will create a partnership and platform that will be hard to penetrate.

He goes on: “We share the same clients and Natural Retreats boasts plenty of relevant leads (it’s not only Rightmove that can supply them).”

His letter concludes: “As sure as night follows day, disruption is coming to estate agencies.

“We should not make the mistake of thinking Purplebricks is a disruptor. They are an agent without shops. The real disruption is when the entire transaction (including completion etc) is all done online.”

He says: “More change will come in the next five years than has come in the previous ten.”

He says that Humberts and Natural Retreats will together leave the big estate agents behind. The letter also makes clear the new owner’s support for Humberts’ franchise model, saying that Spence is “very committed to this” and that the franchisees are “a big part of our future”.
