I moved into this property 2 yrs ago. Unfortunately the central heating ( underfloor heating) never worked. So I survived 2 winters with electric heaters my landlords provided and they also paid the lectricity. But gas & electricity were incl. In rent as per the tenancy agreement. Since last december my landlords have taken £150 off the rent and so fid they the orevious year. Now they want full rent again because it is summer. But they are also renovating the flat underneath me from scratch, new kitchen & bathroom floors plastering walls etc. This has been going on since last November and the noise is driving me insane. Can they ask me to pay the higher rent with the heating issue still not resolved and the constant noise of the construction site in spe? And how much notice for the higher rent do they need to give. Thank you very much for your help.
