The father of a disabled boy denied asking for a 'back-hander' from the builder who constructed an extension for his son.

Lawrence Pickering is suing building contractor JA McConville at Bradford County Court for more than £11,000.

Mr Pickering claims work done by Ashley Deacon, of the firm, on an extension for his son Ryan at their home at Romsey Gardens, Holme Wood, was of poor quality or not completed.

That is denied by Mr Deacon, of Harrogate Road, Bradford.

The extension, which cost £22,000, was paid for through a Disabled Facilities Grant from Bradford Council as Ryan has spina bifida and uses a wheelchair.

The grant was awarded after a High Court battle.

Mr Deacon, who carried out the work, told the court Mr Pickering had advised him to submit an estimate for the work to the Council for £21,840.

Mr Deacon said he had agreed to give Mr Pickering £2,000 and Raymond Sutcliffe, who had introduced the pair, £500 for putting the business his way. "I was not very happy about it," Mr Deacon said.

Judge Peter Benson asked him if he thought this was lawful and Mr Deacon said he did at the time. He said he had been out of work for two or three months and had a large amount of material left.

"The profit margin was such that I knew I could afford it. I was under pressure from Raymond Sutcliffe to go through with it," he said.

Judge Benson said he had doubts about the legality of such an agreement.

Mr Pickering denied asking for £2,000.

He told the court that Mr Deacon had said he would pay him £1,000 for a new kitchen because the old one had to be moved and the units needed to be replaced.

"He said 'If I cannot get it out in one piece, you go and get a kitchen'," Mr Pickering said.

Mr Pickering told the court about a catalogue of claimed problems with the extension.

These included the boiler not working, door handles falling off, uncovered wiring, sliding doors which did not shut properly and damage to an outside wall and paving.

Ian Pennock, for Mr Pickering, asked him why he signed a form saying he was satisfied with the work.

"Mr Deacon said he would come back and make the wiring safe," Mr Pickering said.

Mr Pickering also said builders had left his garden in a mess. David Rose, for JA McConville, said Mr Deacon reported the garden was filthy and another Council official had said the photographs reflected how the garden had looked three years previously.

Mr Pickering denied keeping his garden in that state. Mr Rose also asked Mr Pickering why he did not raise his concerns with the Council's building inspector who came to check the work and he said many were not apparent then.

The case continues.
