FAQs
What size generator do I need for my home or business in Guild?
The correct size depends on the total wattage of the appliances and systems you want to run during an outage. For most homes, a 7–12 kW standby unit will power essentials such as lights, refrigeration, heating and basic electronics. Larger residences or small businesses with HVAC systems, pumps or IT equipment may require 15–25 kW. We offer a complimentary site survey where our engineers list all critical loads, calculate starting (surge) currents, and recommend the most efficient model so you neither overspend nor under-spec.
How quickly will the generator start when mains power fails?
Our automatic standby generators are paired with an ATS (Automatic Transfer Switch) that monitors the grid 24/7. If it detects a loss of utility power, it signals the generator to start within 2–10 seconds, then seamlessly transfers your circuits to generator supply. When mains power is restored and stable, the ATS re-connects you to the grid and cool-down shuts the generator off. You enjoy virtually uninterrupted power with no manual intervention.
What is involved in installing a standby generator in Guild and surrounding areas?
Installation typically takes one to two days and includes: 1) a concrete or steel pad for the generator, 2) running gas (natural gas or LPG) or diesel lines, 3) mounting and wiring the ATS at your distribution board, 4) integrating earthing and bonding to BS 7671 standards, and 5) final load/commissioning tests. Our team handles planning permission checks (usually not needed for units under 50 kVA), liaises with your gas supplier if line upgrades are required, and registers the installation with the local DNO in compliance with G99/G100 regulations.
How often should a generator be serviced and what does maintenance include?
For prime residential standby use, we recommend two visits per year: a minor service every 6 months (oil, filter, coolant, belt and battery checks) and a major service annually (comprehensive inspection, valve adjustment, fuel system treatment and firmware updates). Commercial or prime-power units may need quarterly visits or after every 250 running hours. Our maintenance contracts include load-bank testing to verify the generator can deliver its rated output under real conditions, ensuring reliability when you need it most.
Are your generators fuel efficient and what fuel options are available?
Yes. We supply modern diesel, natural-gas and LPG generators with electronic engine management for optimal fuel burn. Diesel sets consume roughly 0.2–0.24 litres per kWh at 75 % load, while gaseous units can achieve 30–40 % lower operating costs where mains gas is available. We help you compare fuel prices, storage requirements and emission profiles (Stage V/Tier 4 compliance) to choose the most economical and environmentally friendly option for your site.
How loud are the generators and do they meet local noise regulations?
Our standard acoustic-enclosed models produce 60–68 dB(A) at 7 m—about the level of normal conversation—meeting Guild’s typical residential limit of 70 dB(A). For sensitive sites like schools, hospitals or densely populated estates, we offer super-silent canopies (as low as 55 dB(A)) and custom attenuators. During the survey we measure background noise and design an installation that stays within your council’s day- and night-time decibel thresholds.
