About Us


Hi, I'm Andy Ball and I've worked in the world of property for the majority of my working life.

I set up as a Sole Trader in 2005 and have been undertaking Standard Assessment Procedure (SAP) home energy rating calculations continually since then.

My clients have ranged from self-builders to architects, through to some of the top 10 housebuilding firms in the country.

Despite being based close to the Malvern Hills, just on the Herefordshire / Worcestershire border, I'm able to cover work anywhere within England and Wales and have undertaken SAP assessments on properties in the majority of the English counties.

I'm accredited with National Home Energy Ratings (NHER) and am a qualified On Construction Domestic Energy Assessor (OCDEA).

I have a Bsc  Open University Degree in I.T. / Management.

As part of the arrangement with my accreditation body my work is subject to regular, routine audit and I currently hold £2m Professional Indemnity Insurance.
