They are claiming that of the £8.5k already paid, only £1600 is of a standard they believe is correct/acceptable and that the balance needs to be returned.
Their payments were made of an intial deposit to secure our time, then 2 interim payments for works in progress, each invoice presented for their payment if satisfied as per the agreed terms. The works consisted of refurb of front living room and hallway - incorporating a lot of prep work, - eg strip all wallpaper, plaster all walls, ceilings, supply & hang new doors/ furniture build new media units, strip floorbaords, insulate under floor.... so quite labour intensive in the prep with the finishing left to do, to create the completed article.
Numerous delays from client over deliberations and alterations once started - all documented with further letters of instructuon being drafted by me incorporating their revised choices.
Their experts report documents items we were yet to do, (hang wallpaper, decorate, fit client supplied electrical sockets) but all documented as a poor standard?.
The payments to date cover all my epxenses for: the front end liaison, labour for the prepartion of all works, purchase of all materials, (including paint and wallpaper adhesive), plant, trades and VAT.
Their breakdown of the £1600 is totaly spurious and is their take on costs.
