In depth

Understand the property decision before choosing.

Retrofit assessment referral sits within Energy and sustainability → Energy assessment and planning → Performance, bills and retrofit → Energy-improvement routes. The practical route depends on property type, energy data, systems, comfort or operational issues, investment horizon.

Owners and organisations planning energy or carbon improvements. Mayfair begins with the required outcome and the existing property or product conditions before comparing repair, replacement, supply, installation, professional or programme options.

Energy assessment, certification and regulated advice require the appropriate qualified route.

Cost and programme are not inferred from the page title alone. Mayfair checks property type, energy data, systems, together with quantity, property access, timing, preparatory work and the delivery model before tailored guidance is given.

The guidance is supported by Ministry of Housing, Communities and Local Government, UK Green Building Council, Google Search Central. Source links and review dates are shown on the page so customers can distinguish general Mayfair guidance from statutory, professional or regulator information.

Mayfair keeps the selected property-service context in the Property AI handoff, including the exact route and any location chosen, so the conversation begins here rather than starting again.
