THERE’S nothing outside the elegant stucco Chelsea townhouse to indicate the extraordinary things that go on inside.

Nothing to show why the rich, famous and just plain troubled now store this discreet address in their BlackBerries. A peer of the realm and a young woman stand on the pavement chatting. “It’s great that you’re also dealing with your sex compulsion,” she says. He smiles.

“Is that an acupuncture stud in your ear?” he answers.

“No,” she responds. “A magnet. I press it to release endorphins and serotonin.” These are patients at The Recovery Centre, a private clinic that offers just five clients at any time for £1,200 a day a bespoke treatment for addictions within the walls of a smart residential London house. There is a choice of more than 80 freelance counsellors plus some off-beat “therapies” ‹ from playing polo, gokarting and watching butterflies to shopping in Bond Street with a personal shopper, about which more later.

Despite its bizarre approach and high fees, such is the demand that within little more than six months of opening in November last year, the owners have rejected a bid to be bought out and are now planning further centres in Notting Hill, Primrose Hill and the City.

The centre is the brainchild of Charisse Cooke, 29, a south African psychologist, and Robert Batt, 40, a former drug addict and aristocrat who, aged six, inherited his family’s Norfolk estate and 24 cottages. He swapped snorting “shed-loads” of cocaine, spending £50,000 on shopping in one day and driving one of his Ferraris drunkenly through a field for eight years of personal recovery, a psychology masters degree and personally financing The Recovery Centre.

Cooke and Batt’s brand of therapy attracts aristocrats, rock stars and millionaires.

It has become the treatment centre of choice for one supermodel.

“An estimated one in 10 of the population suffers from addiction,” says Dr Robert Lefever, a world authority on the subject and the man for whom Batt and Cooke worked for five years at the Promis clinic.

I’m visiting the centre to experience two days of treatment ‹ to top up the regular therapy I’ve been doing for the past 19 years after successfully recovering from an eating disorder, amphetamine addiction and alcoholism in my early twenties.

I came from a classic dysfunctional family ‹ my mother walked out when I was 12 and before that I’d had to deal with her mental illness. When I was 21 and at Bristol University, I saw a consultant psychiatrist in Harley Street. I was so intimidated at having to expose myself psychologically that I would take amphetamines before visits. The psychiatrist helped me but also colluded in my addictive behaviour. “You’re not an addict,” said the good doctor.

“You don’t take pills every day.” When I went to work in Fleet Street, I started drinking and bingeing. I appeared to have it all: a good job, nice flat, fast car, friends. But inside I was desolate, lonely and often suicidal. It was after I spent a weekend hidden in my flat alone, crying inconsolably that a friend with whom I’d lived told me about Promis.

She talked openly about her eating disorder ‹ which had been such a shameful and secretive disease for me..

She was full of hope and happiness. So I checked into Promis for addiction counselling. After that, I spent five years in psychoanalysis and graduated to a psychoanalytical psychotherapy group.

Treatment at Promis saved my life ‹ but it was tough love. So I’m curious to see how different the luxury atmosphere of The Recovery Centre will be.

Cooke greets me wreathed in smiles.

“We were just talking about Treatment Chic,” she laughs, sporting a Hermès belt. I nip into the bathroom: it’s marble with fluffy white towels, Jo Malone soap and luxurious Diptique candles burning. But this is no urban retreatstyle spa. If addicts are recovering here, there will also be tears and hurt aplenty.

It’s 9am and time for my appointment with Cooke, who has designed my personal programme. Questions cover everything from whether I’ve ever prostituted myself to whether I suffer from sexual anorexia, exercise obsession or have a criminal history. Having said no to the first two and admitted to shoplifting, aged 19, and a nascent exercise obsession, we move on. I leave the session feeling exposed and vulnerable.

In between sessions, staff waft in and out like First Class air stewards saying, “Can I get you anything?” and returning with nuts and herbal teas. At lunch with four patients and Cooke, the chef dishes up risotto with black truffle shavings followed by sea bass on rocket salad. The food may be fancy but conversation is authentic and poignant. A 24-year-old patient talks about the day her four-year-old son watched “problem drinkers” on Jeremy Kylie’s show then asked: “Mummy, are you an alcoholic?” Cooke hugs her.

By mid-afternoon I’ve already had three sessions: an interview with a psychologist, some experiential dynamic psychotherapy (AEDP) and 50 minutes with a performance enhancement specialist and have a cracking headache from such intensity. But it’s time for group therapy with Batt. Wearing a Savile Row suit and speaking like a Coldstream Guard, the regiment founded by his family, Batt prods and pokes psychologically.

Batt says he’s watching my eyes darting around, “filtering” what I’m going to say. He remarks upon my breathing becoming more shallow. “I feel tearful,” he adds, wanting me to talk, “as if my gut is being wrenched and contorted.” I squirm. I’m not used to therapists sharing their emotions.

Immediately after group therapy, Cooke bounces in giggling. “Hello lovely ladies. Let’s change the atmosphere in here. Let’s play a game.” We each pull a piece of paper out of a glass and follow its directions. “Your secret wish …” is one. “Reveal your most embarrassing moment Š” is another.

My answer? Running down a Kensington street as a dare, stoned and wearing only a moped helmet. It’s the kind of party game I’d play when I was drunk.

Puerile perhaps. But it offers welcome light relief. This style of treatment is Batt and Cooke’s idiosyncratic vision: the way that Batt himself got “clean”.

Aged 14, he drank a litre of whisky at Harrow, spent two days unconscious while friends shouted out his name in roll call, then graduated to a cocaine and shopping habit. Batt got clean with the help of friends, (“other recovering addicts”) and an ongoing mixture of “yoga, therapy, helping other people, contemplating nature, having fun and med- itation”. With this in mind, he recently directed one patient to take creative writing lessons with novelist Raffaella Barker; escorted another to the Syon Park butterfly house (“It helped him get in touch with his inner child”); refused to treat one unless she took tap-dancing lessons; and sent several out shopping with Sally Bardsley, erstwhile personal stylist to Princess Diana and Madonna.

Some critics will find these bizarre therapies silly. Others, like myself, may consider the hugging, hand-holding and the overlap between therapists with patients to be lacking in boundaries.

I am slightly apprehensive on my second day. What is in store for me? A former theatre director turned drama therapist (“I believe in anonymity,” he says,) works with four of us. “When you were young, who was the dominant character in your household and what were their Ten Commandments (or rules)?” We write our lists, my mother’s “Commandments” suddenly spilling out of me. Then we enact a dinner scene, each member of the group becoming one of my family members, to debate the “rules”.

NEXT in art therapy with Maddi Strong we use plastic toys to enact stories that become very self-revealing.

The Recovery Centre believes in creative “play”. “Psychoanalysis and long-term therapies have their place in treating addictions,” says Charisse. “However, addicts initially respond more readily to more humanistic and supportive therapies.” After two days, I feel wrung-out but also empowered. In each of the sessions I have learned something useful about myself, something to fine-tune my recovery, and I have also had some fun. My own experience of early recovery was that it was very painful facing my demons without the “anaesthetic”.

It’s too early to tell whether Batt’s patients will achieve long-term recovery.

But they seem to be getting well.

You could argue the centre’s approach is elitist, recovery only for the wealthy.

Fortunately, most people get well ‹ for no more than minimal voluntary donations ‹ through fellowships like Alcoholics Anonymous in draughty church halls.

But to focus on the centre’s “swish” factor is to miss the point. “If you’re at rock bottom, lobster and cream carpets won’t heal you,” comments NHS and private psychotherapist Lili Reinisch.
