Secure Park Heathrow Ltd

One customer, Vimel, revealed that he returned from Kenya to find a substantial amount of paint on his car, as well as scratches on his windscreen where it had appeared the rep from Secure Park Heathrow Ltd had tried to scrape the paint off. When Vimel reported this to the company boss, he was surprised by what happened next: "He arrived at the car, didn't introduce himself, just walked straight up to the vehicle and spat on the windscreen and tried to wipe off the scratches," Vimel explained.

The Rose family came home to find part of their car missing. As Daniel Rose turned on the car engine to leave Secure Park Heathrow Ltd, he noticed a strange sound which prompted him to check his car when he arrived home. The catalytic converter was missing, as well as a large section of the exhaust. However, a missing catalytic converter is one thing, but one customer returned from Australia to find that his vehicle had been stolen altogether.

Jill and Derek Gridley came back from holiday to find their car intact, and even gave Secure Park Heathrow Ltd good feedback. However, 30 days later they received parking tickets for approximately £120. Their car had been parked on Slough's High Street, so not quite the secure parking that they had paid for.

The elusive men involved in the running of Secure Park Heathrow Ltd are Dominic Almond and Matthew Grant, both of whom are hard to get hold of. Neither Dominic nor Matthew has given a satisfactory explanation to the disgruntled customers who contacted us.

That's where Rogue Traders comes in. We equipped three cars - a Toyota Yaris, a brand new Mercedes and a 3 litre Audi A6 - with our trademark secret cameras. Our team handed them over to Secure Park Heathrow Ltd over the course of a month to see what really happens to cars they are supposed to look after.

Our expert Tim Shallcross explains that we should rightfully expect "a locked compound, security lighting and cameras, no authorised access and above all, the cars should be driven straight there and straight back to meet us off the plane."

This, however, is not the case. We repeatedly checked out what appeared to be their main secure compound. It was locked up at night but during the day the gates were left open, and there was no sign of CCTV. We could drive straight in and touch all the cars and we even found customer flight details left on full view in car windscreens.

As for our cars, the Toyota left Terminal 1 and was first driven to a recreational ground: public land owned by the council, land that the driver doesn't have permission to use. "Parking in a council owned car park is just asking for trouble. It's got full access to the public, you don't know who's going in there, who's going out of there, it's simply not secure," explains Tim.

After being left there for an hour the Toyota was driven to the not-so-secure compound off a main road, and left for several days together with our Mercedes. The night before the cars are due to be returned to us, they were moved again - the Mercedes was left in the street, while the Toyota was driven to the council car park, both of which were unattended all night.

Tim explains: 'Parking in residential streets is not secure... cars do get damaged, they get scratched, they get broken into and stuff gets pinched out of them'.

The next morning, three hours before the Mercedes was due to be returned to us, it seemed to have become a taxi for Secure Park's staff as they ferried drivers to and from Heathrow. A driver is caught on camera driving in an aggressive manner, others were found using mobile phones whilst driving and one was caught speeding - clocking up 69mph in a 40mph zone. If that wasn't enough, they also used one of our cars as a place to sleep.

On the last run to the airport, we hear staff discussing other customer's cars, revealing that they keep some cars on their front drives. Later, our tracker records the Audi doing over a 100mph in a 50mph zone - that's twice the speed limit and an instant driving ban.

So it was time for us to get some answers to our questions. Tracking down the company bosses, Matthew Grant and Dominic Almond, isn't easy - the company address they give on their notepaper appears to be another business altogether. However, we did some digging and found that Dominic Almond also runs a pub, The Union Inn in Old Windsor.

When we approached him and Matt put forward all the problems and issues we discovered with Secure Park Heathrow Ltd, Dominic denied any knowledge, stating that he doesn't actually 'run this side of the company anymore'. However, he offered to look into the problems and give proper answers to the allegations put to him.
