As poorly performing assets, future options included disposal, new build, refurbishment and deep retrofit under SHP’s aim of providing residents with warmer, healthier, and more affordable homes whilst aiding their journey to net zero carbon.
Upon securing grant funding for a retrofit programme we supported a tender process comprising approximately 100 properties. Eight properties were identified as pilots under phase 1, with the objective of potentially paving the way for net zero energy retrofitting at scale, radically changing the approach to energy efficiency and helping eradicate fuel poverty across the Borough.
Energiesprong was selected as the retrofit solution. Originating in Holland, this Dutch retrofit concept has been subject to numerous industry awards in recent years including World Green Building Council award in 2018 and Ashden Award in the UK Sustainable Buildings category 2019.

The retrofit works achieve a high performing net zero home by adopting a fabric first approach and incorporating a fully integrated Factory Zero energy module to support smart heating, ventilation and cooling. Specific improvements include triple glazed windows and doors, external wall insulation (EWI), pre-fabricated insulated rooftops incorporating photovoltaic panels (PV) and a new heating system (air source heat pump) with mechanical ventilation with heat recovery (MVHR). The Energiesprong concept is based around an Energy Plan which does away with traditional utility bills and is backed by a 30-year warranty on energy and indoor climate performance.
With works typically programmed to complete in 10-15 days and with residents in occupation, the Energiesprong model acts as an effective and efficient future proof solution to tackling poor energy performance of existing buildings and is part of the Mayor of London’s Retrofit Accelerator.
Works commenced in Jan 2021 with Engie UK & Ireland appointed as Principal Contractor for the initial Phase 1 Contract.
