About this business
A specialist that installs and maintains water quality sensors, dosing equipment and private water treatment for farms, rural homes and food businesses. Six people work from a leased rural base outside Belfast, and the business could be moved. It opened in 2018.
Revenue has grown every year, from £626k in 2021 to £740k, yet adjusted EBITDA has slid from £132k to £110k over the same period. Net profit is £89k. A buyer would want to understand the cost increases behind that; the asking price is £500k.
Key investment highlights
- Turnover up 18% since 2021
- Sensors, dosing and private water treatment
- Team of six
- Rural base could relocate
Reason for sale
