I am the freeholder of a block of 4 purpose built flats in Brighton, that comprises of 2 flats on the ground floor, and 2 on the 1st floor. One of the ground floor flats is going to be sold, and apparently I have to arrange for an asbestos survey for the common parts and a fire risk assessment of the building. Please can any of you recommend someone / a company suitably qualified to carry out such work ?
