The £36m turnover Fareham-based insulation and renewables contractor has appointed administrators from PwC triggering the loss of 92 jobs.

The Trustmark-accredited energy efficiency provider was heavily reliant on government-funded domestic retrofit programmes, with the Great British Insulation Scheme and Energy Company Obligation providing the bulk of its revenues.

Installation volumes fell sharply in recent months, squeezing margins and cash flow.

The decisive blow came as the sector faced uncertainty over what replaces GBIS and ECO beyond March 2026.

Following a government consultation on the future of retrofit support, energy suppliers paused new commitments, effectively cutting off new work and leaving the company with no forward pipeline.

Despite efforts to stabilise the business, including exploring restructuring and sale options, no solvent solution could be secured.

South Coast Insulation operated nationally from its Hampshire headquarters with depots in Devon and Liverpool, delivering insulation, ventilation upgrades and air-source heat pump installations.

The administration affects South Coast Insulation Services Limited only with eight staff retained to support essential wind-down activities and recover outstanding debts.

Other group entities remain solvent and continue to trade.
