Energy Solutions

Turnkey multi-measure upgrades that cut what your property costs to run.

Solar PV Installations

Solar PV installation designed around your roof, your shading and how you actually use electricity. As MCS certified solar panel installers, we size the system, fit the panels, inverter and battery storage, and sort the paperwork you need to get paid for exports.

Air Source Heat Pump Installers

MCS certified air source heat pump installation for homes and businesses, fitted by our own engineers. Every system is sized from a room-by-room heat loss survey, so it keeps every room warm and runs as efficiently as it was designed to, all year round.

Complete Heating System Upgrades

Complete heating system upgrades for homes and businesses, not just a boiler swap. Our Gas Safe engineers replace boilers, radiators, pipework and controls as one job, giving you a new central heating system that heats every room properly and runs efficiently.

Loft Insulation

Loft insulation fitted to the recommended depth by our own installers, usually in a single day. We check what's already up there, keep the eaves clear for ventilation, and leave you with a warmer house and less heat escaping through the roof.

External Wall Insulation & Rendering

Solid wall insulation for older homes, fitted to the outside of the house and finished with a new render. Our own installers cut the heat lost through your walls, protect the brickwork from the weather and give the exterior a clean, modern finish.

Single Storey Extension

Single storey extensions designed, built and finished by one in-house team. We handle the drawings, planning checks and building control, then build from the foundations to the final coat of paint, on one fixed-price quote.

Loft Conversions

Loft conversions designed, built and finished by one team, whether that's a Velux, a dormer loft conversion or a hip-to-gable. We check the headroom, structure and stairs first, handle building control, and turn dead roof space into a room you'll actually use.

Kitchen Renovations

Kitchen renovations handled from start to finish by one team. We strip out the old kitchen, update the plumbing and electrics, and our own kitchen fitters install your new units and worktops, with one fixed-price quote covering every trade.

Living Room Improvements

Living room improvements that go beyond decorating. We reconfigure the space, build custom media walls, update the lighting and electrics, then replaster and finish the room, all handled by our own in-house team on one fixed-price quote.

Commercial Planned Maintenance

Planned preventative maintenance for offices, shops and commercial buildings. Our in-house team services heating, electrics and building fabric on a fixed PPM schedule across your sites, so small faults are fixed early and your premises stay open.
