AVG BILL SAVING
— WHY UPGRADE —
Six Reasons to Upgrade
Your Energy Efficiency.
Energy prices aren't coming down. The best hedge is using less — and using it smarter.
Immediate Bill
Savings
LED lighting alone can cut your lighting energy use by up to 80%. Add smart controls and occupancy sensors and the savings compound — visible from your very first bill.
Lower Carbon
Footprint
Using less energy means generating less carbon. Energy efficiency upgrades are one of the fastest, most cost-effective ways to reduce your property's environmental impact.
Smarter Controls
Smart thermostats, occupancy sensors, and time-of-use scheduling mean your energy system works around you — not the other way around. Heat and light only what you need, when you need it.
Better EPC
Rating
Energy efficiency improvements directly improve your EPC rating — increasingly important for landlords, sellers, and commercial tenants facing minimum EPC requirements.
Commercial
Compliance
ESOS (Energy Savings Opportunity Scheme) and SECR reporting requirements are tightening. We help commercial clients identify and implement measures that count towards compliance.
NICEIC Approved
All energy efficiency electrical work is carried out by our NICEIC approved engineers. Properly installed, fully certificated — not DIY fixes that void your insurance.

— FREQUENTLY ASK QUESTION
Energy Efficiency Questions, Answered.
Common questions about energy efficiency upgrades for homes, businesses, and schools. Still unsure? Give us a call.
What's the quickest way to reduce my energy bills?
LED lighting is typically the fastest and highest-impact change — it can cut your lighting energy use by up to 80% from day one. After that, smart heating controls and occupancy sensors deliver the next biggest savings. We'll advise on the right combination for your property during a free survey.
Do you carry out an energy audit before quoting?
Yes. For larger projects, we carry out a site assessment to understand your current energy usage, identify the highest-impact opportunities, and build a package that delivers the best return. For straightforward LED or smart control installs, we can quote from a brief description or floor plan.
Will energy efficiency upgrades improve my EPC rating?
Yes. LED lighting, smart heating controls, and other efficiency measures all contribute positively to your Energy Performance Certificate rating. This matters for landlords (minimum EPC requirements are tightening), sellers, and commercial tenants.
Can you integrate smart controls with my existing heating system?
In most cases, yes. Smart thermostats like Hive, Nest, and Drayton Wiser are compatible with the majority of boiler and heating systems. We assess your system during the survey and confirm compatibility before recommending a solution.
Do commercial premises need specialist energy efficiency work?
Commercial premises often benefit from measures beyond residential upgrades — power factor correction, building energy management systems (BEMS), and demand-side response wiring. We carry out all of these and can advise on ESOS and SECR compliance requirements as part of the assessment.
