About us

We have been full time professional landlords for 14 years. We have built up a family business with 17 properties to rent, as part of this portfolio we have a building with 5 studio flats which provides communal utilities where we reduced gas costs 50%.


We have a 100-year-old 5-bed house where we reduced gas bills from £2500 to £900 pa, and improved the EPC from F to almost A.

We built a block of 6 flats where the EPC is now B.

The best time to do a retrofit is when a home owner is planning to redecorate their property and or upgrade their boiler.
