Orbit Homes says it is not liable for the raw sewage which flooded the new home of a Burton Latimer family just two months after they moved in.
Emily Fearnley and Chris Allen bought their home in Virginia Crescent in October last year, but were forced to spend Christmas in a hotel after it flooded.
They claim they deserve compensation for their nightmare, with Anglian Water already saying it is not at fault as illegal rubble dumping caused a blockage.
Orbit Homes divisional managing director Andrew McDermott says they are not liable to pay compensation.
He said: “We understand this has been a disruptive and upsetting time for Mr Allen and Miss Fearnley, and we have been in regular contact with them to offer our support while the issues were being rectified by Anglian Water.
“We wouldn’t wish for any customer to go through this experience when buying a new home.
“Although Orbit is not liable to pay compensation, we have offered a significant goodwill gesture to Mr Allen and Miss Fearnley, which they have agreed to accept.
“The couple have expressed their thanks and appreciation.
“We hope Anglian Water does all it can to prevent this from happening again.”
Miss Fearnley says the incident left the family extremely out of pocket.
She told the Northants Telegraph: “We moved into the new-build but came home one day to find our driveway overflowing.
“We entered the house to discover our downstairs covered in dirty sewage water which had come up and the water continued to keep flowing.
“It completely destroyed downstairs and outside and we had to stay in a Premier Inn for seven weeks over Christmas.
“We were given minimal money to live on and buy food with and are extremely out of pocket and always will be unless we get the compensation we deserve.”
An Anglian Water spokesman said four tonnes of debris needed to be cleared.
The spokesman said: “Sadly illegal dumping in sewers happens all too often and has devastating affects like those experienced here by Mr Allen and Miss Fearnley.
“We know how unpleasant any kind of flooding is and do understand how upsetting this must have been for them both in their brand new home.
“The flooding was caused by a massive blockage of rubble and debris, wrongfully placed in our sewers.
“This caused sewage to back up and overflow into the garden and house.
“About four tonnes of debris needed to be cleared from the brand new sewer pipe by our teams, who attended site as soon as we were made aware of the problem.
“Our teams also carried out CCTV surveys of the pipe and found no issues with the newly installed system.”
