Extensions- 21 Dec 2021
Would not recommend these to anybody. They consist of Father Tony, Gareth (GWT) son and Ted - son. They started our New Build in March this year with a finish date Mid September. The schedule was amended and another date provided of the first week of November, this was amended to the 17th of November. We requested a finish date, they didn't provide one, so we accepted that they would leave site. They have left us with lots of problems, took a deposit for Air Source Heating but did not pay it over to them. We needed the build to be completed by the latest the end of January, we have not got the second fix done yet, no interior. We would estimate there is three to four months work yet, which makes it March 2021 ( A year when 6 months was quoted). There has not been any delays due to supplies and Covid, we have had a kitchen sat on site for 3 Months in line with there latest schedule. We strongly recommend that these be given a wide birth. They have passed on comments about ourselves, making it difficult for us to access tradesmen.
