Overton upgrades fire stations: M&E integration and continuity lessons for engineers

30 Second Briefing
Overton Electrical Services has completed HVAC and electrical upgrades at Chesterfield and Alfreton fire stations for Derbyshire Fire and Rescue Service, replacing air conditioning plant and refrigerant pipework at Chesterfield and integrating new room and central controls with existing heat recovery ventilation. At Alfreton, new heating and cooling systems, revised ventilation to occupational health areas and associated electrical supply works have been installed and commissioned. Acting as main contractor, Overton coordinated mechanical, electrical and building interfaces to maintain 24/7 station operations while delivering fully tested and commissioned systems.
Technical Brief
- New refrigerant pipework at Chesterfield required integration with legacy heat recovery ventilation without interrupting operation.
- Initial air-conditioning plant shortages were mitigated by direct coordination with the manufacturer to hold programme.
- Overton acted as main contractor, managing mechanical–electrical–building interfaces under live 24/7 emergency response constraints.
- Testing, commissioning and formal handover were treated as critical safety gates before operational acceptance at both stations.
- Occupational health accommodation at Alfreton received revised ventilation layouts to better control exposure in clinical areas.
- Electrical supply upgrades at Alfreton were sequenced to maintain redundancy for critical response and communications systems.
- Integration of new controls with existing systems demanded careful phasing to avoid unplanned shutdowns of HVAC serving crew areas.
- For similar blue‑light facilities, the scheme underlines the need for construction staging around emergency response availability.
Our Take
Overton Electrical Services now appears in our database both on public-safety infrastructure with Derbyshire Fire and Rescue Service and on retail M&E works for Vodafone’s nationwide rebrand, signalling a contractor comfortable straddling regulated emergency services and fast-track commercial roll-outs in the UK.
For Derbyshire Fire and Rescue Service, using a contractor already engaged in a national VodafoneThree programme suggests a preference for suppliers with scalable delivery capacity, which can reduce interface risk when multiple stations or sites are upgraded in short succession.
