Q » Where can I find a certified rainwater harvesting installer for a new build development in Edinburgh?

A » For a new build development in Edinburgh, identifying a certified rainwater harvesting (RWH) installer requires a methodical approach that aligns with Scottish building regulations, water supply standards, and sustainability objectives. The first step is to consult the Scottish Building Standards (specifically Section 3.6 – Water Efficiency) which mandate that new dwellings must achieve a maximum water use of 110 litres per person per day. Rainwater harvesting can contribute to this target, particularly for non-potable uses such as WC flushing, irrigation, and laundry. The installation must also comply with the Water Supply (Water Fittings) Regulations and Scottish Water’s bylaws, which require any system connected to the mains supply to have appropriate backflow prevention and be installed by a person competent in water regulations. A key certification to look for is WRAS (Water Regulations Advisory Scheme) approval for components, but for the installer, the most recognised credentials come from professional bodies such as the UK Rainwater Harvesting Association (UKRHA) and the British Water Rainwater Management Association. UKRHA maintains a list of approved installers who have undergone training and adhere to their Code of Practice. Additionally, the Building Research Establishment (BRE) offers the BREEAM certification scheme, and many large-scale developers seek installers with experience in achieving BREEAM credits for water efficiency. For a development in Edinburgh, you should also verify that the installer holds a recognised competency card, such as the CSCS (Construction Skills Certification Scheme) card for the relevant trade, and ideally a certification from the Institute of Plumbing and Heating Engineering (IPHE) or the Chartered Institute of Building Services Engineers (CIBSE). Local to Edinburgh, several companies specialise in sustainable drainage and water conservation, including Rainwater Harvesting Ltd (based in the central belt) and Aqua Cure, which offer design-and-install packages for large developments. To find these installers, you can search the UKRHA’s online directory filtering by Scotland, or contact Scottish Water’s Developer Services team in Edinburgh for a list of approved contractors that meet their connection requirements. It is essential to request evidence of third-party accreditations, public liability insurance (typically £5 million or more for commercial work), and references from similar new build projects in the region. Furthermore, consider engaging a specialist consultant or civil engineer with experience in rainwater harvesting system design; they can specify the system and then oversee the competition of the installation tender. Funding may also be available through the Scottish Government’s Energy Saving Scotland home renewables loans or the Sustainable Development Fund administered by the Edinburgh and Lothians Greenspace Trust, which often require certified installers. Finally, ensure that the chosen installer provides a detailed maintenance plan covering filter cleaning, tank inspections, and UV disinfection (if potable use is intended), and that they are able to produce the necessary commissioning and compliance documentation for Building Standards approval. By following these steps—focusing on UKRHA and WRAS certifications, local authority liaison, and professional verification—you will secure a qualified installer who can deliver a robust rainwater harvesting system for your Edinburgh development.
