A crooked plumber who went to jail for ripping off customers is facing a second spell inside after he did exactly the same thing when he came out.

Gary Henry sent a £10,000 invoice to nuns at the Sisters of Poor Clares at Lynton Monastery, in which he overcharged them for work he had carried out, before he was jailed in August 2015.

He went on carry out shoddy work at the bathroom of the home of a pensioner in Bishops Nympton for which he also charged too much.

Henry, 58, of Anstey Way, Instow, admitted fraud and two counts of contravening the requirements of professional diligence when he appeared at Exeter Crown Court on Friday.

Judge David Evans adjourned his case for sentence until August 10.

He bailed him but told him: “The fact that I am ordering a probation report should not give you any hope about the sentence. All options including immediate custody will be open to the judge.”

Henry admitted fraud in the case involving work he carrier out on the central heating system at the monastery in Lynton, North Devon in 2011.

He had done the work earlier but after his release from a two year sentence in mid 2016 the former fireman sent an invoice to the parish priest responsible for the monastry’s finances, between November 1, 2016 and December 31, 2016.

The bill was for £10,239.76, which over claimed for the amount of time taken on the job, claimed for more copper pipe than was used, overcharged for VAT, and charged ‘an exorbitant hourly rate’.

The professional diligence charges relate to work he did at the bathroom of a female pensioner’s home in Bishops Nympton between March and May, 2017.

His work on a hot water cylinder and shower was so shoddy that neither worked properly and the elderly customer struggled to use the shower at all.

Henry was branded as arrogant and a rogue trader by the judge who jailed him for two years at Exeter Crown in 2015.

In that case, he was found guilty of three counts of fraud and three of failing to apply professional diligence and admitted two counts of unfair trading.

He charged three customers up to twice the going rate for shoddy work on stoves and boilers after luring them in with low verbal estimates.

He lied about being authorised to work on heating systems and left angry customers facing even bigger bills to have his work sorted out by properly certified and reputable engineers.

Henry was caught after he overcharged a pensioner without realising she was a local councillor who reported him to Devon’s Trading Standards Department.

Speaking after the hearing, Councillor Rufus Gilbert, Devon County Council’s Cabinet Member with responsibility for Trading Standards, said: “I encourage anyone who suspects they have been a victim of a rogue trader to come forward.

“Rogue Traders use high pressure sales techniques and their work is often sub-standard or not required at all at best or dangerous and potentially life threatening at worst.

“They undermine legitimate traders who are trying to make an honest living.”
