Doing a bit of ferretting it appears he bought his house on Shakespeare Road April 1998 so will just be getting towards the end of his mortgage. Looking at Rightmove sold prices nye on doubled over 10 years, no reason to think they would have doubled again in the subsequent 10 to 12 years. So to put a capital value on the roof over his family say as much as £1.3 mil. From the google view it looks like they have spent money on it, roof lights evident sugessting a reconfiguration, so may be remortgaged. His Limited company shows little liquidity circa £50,000.
Nothing to indicate Claire and Desmond left fortunes to him or his older brother and sister.
Married in 1992 Jay's wife works as an editor specialising in education currently senior at UCL Press, probably well paid, she sometimes sings when Jay plays with his Jazz quartet, she doesn't have any other current Company House presence apart from as a director of his self named company.
If that projection of £1.9 mil is based on anything it's possible they may have holiday property somewhere, but I can't see any trace...
It looks like they are a hardworking middle class couple with a son Eddie, according to a piece in Esquire they jointly wrote, they went through difficult fertility treatment to conceive.
They are mid fifties and have earned through their lives. Not particularly loaded but not uncomfortable, and it doesn't look like they are in a position to sit back and do nothing.
But this is just based on shit from the internet...
