We recently sold our L&Q flat and knew about the possible works and the 5k cap. What we didn't know was when it was happening. It ended up being whilst we were selling and as part of the deal we agreed to pay up to 5k for the buyers. The external works have been completed but I have no idea whether they will have cost the full 5k or not. Do you have no idea what work has been done? We were in a house divided into two flats and yhey erected scaffolding, repaired some external stone work, painted a bit and repaired a bit of guttering from what I can see. Npw we have to wait for the invoice. ..but have no idea how long that will take and if we'll even get it or whether we'll just hear via our solicitors. It says it could be up to 18 months before they issue yhe invoice but the fact you have received yours as already is a good sign. Did you not have any idea major works were happening?
