Services
Air Source Heat Pumps
We design and install air source heat pumps that extract warmth from the environment to provide low-carbon heating and hot water. Our MCS-certified engineers ensure proper sizing through room-by-room heat loss calculations, integrating systems with existing setups where appropriate. Each installation includes post-completion efficiency checks and customer training on system operation and maintenance.
Loft Insulation
Our retrofit specialists install high-performance loft insulation to prevent heat loss and reduce energy bills. As part of whole-house assessments, we determine optimal insulation thickness and recommend complementary measures. All installations comply with PAS 2035:2019 standards and qualify for our 25-year Insurance Backed Guarantee.
Solar PV Systems
We supply and fit solar photovoltaic systems that generate renewable electricity for residential properties. Our solutions include system design optimisation, grid connection assessment, and performance monitoring advice. Installations meet current MCS requirements and can be combined with battery storage solutions for enhanced energy independence.
Boilers and Heating Systems
Our GasSafe-certified engineers provide complete heating system upgrades including boiler replacements and underfloor heating integration. We specialise in transitioning properties to low-carbon alternatives while maintaining comfort levels. All work includes system efficiency testing and compliance certification to current building regulations.
Heat Pump Servicing
We offer annual servicing packages for air source heat pumps to maintain optimal performance. Our engineers conduct comprehensive checks including temperature calibration, pressure testing, and electrical safety inspections. Regular maintenance helps preserve system efficiency and extends equipment lifespan while maintaining warranty validity.
