FAQs

Match the generator's continuous output to the running load of the tool, allowing for the tool's start-up surge (typically 2-4× running load for motor-start tools). For a 2-kW power tool, a 4-5 kW generator handles both running and start-up reliably. Multiple tools running simultaneously add up — calculate worst-case combined start-up load. The continuous and peak ratings are listed on every generator product page.

Generator parts — voltage regulators, alternator brushes, fuel filters, air filters, oil filters, spark plugs, starter motors, recoil-start assemblies, and engine consumables — are available for the majority of common workshop and trade-grade petrol and diesel generators. Search by the manufacturer's part number or by the engine and alternator model codes stamped on the unit. If the part is not listed, WhatsApp 07754288583 with the generator make, model, and a clear photograph of the failed component and we will confirm availability.

UK construction-site safety guidance (HSE / CDM) recommends 110V centre-tapped tools and lighting for safer operation in damp, dusty, and ground-contact conditions — at 110V centre-tapped, the voltage to ground is 55V, significantly reducing the shock hazard of accidental contact. Site transformers step the 230V mains down to the safer 110V supply. Most major construction contractors and the principal tool-hire companies operate 110V kit on-site for this reason.

Petrol generators are lighter, cheaper, and start easily in cold conditions — the standard for portable, intermittent-use, and lower-output applications (typically up to 5 kW). Diesel generators are heavier, more durable, more fuel-efficient at sustained load, and rated for longer run-times — the standard for site-power, standby applications, and outputs above 5 kW. Diesel generators also share fuel with most plant equipment, simplifying yard fuel logistics.

Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the United Kingdom. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will typically arrange collection and replacement at no cost to you. For parts that don't fit your machine, the Fit Guarantee covers a hassle-free return at no cost. For buyer's remorse — you've changed your mind or ordered the wrong item, email us first to obtain a Return Merchandise Number; a restocking fee may apply. Refunds are issued to the original payment method once the return is inspected.

Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and 'Check where we deliver' confirms coverage for your postcode before you order. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa.

Generators & Transformers

Within Power Tools & Accessories, Generators & Transformers covers the portable and workshop-mounted power-supply equipment used in fleet workshops, mobile-service operations, on-site work, and standby-power applications — petrol and diesel generators for off-grid and standby power, and transformers (typically 110V site transformers and isolation transformers) for safety-rated tool operation on construction and industrial sites. Generators are sized by output in kVA or watts and rated for the loads they support — small generators (1-2 kW) for trickle-power and lighting, mid-range generators (3-5 kW) for power-tool operation and emergency standby, and large generators (5+ kW, often diesel) for site-power and heavy-duty load support.

Parts For Machines supplies generators and transformers, and — central to the practical use of this section — replacement parts and service consumables for generators already in the field. Buyer queries reaching this category are dominated by parts and rebuild-kit lookups: alternator parts, voltage regulators, starter motors, fuel filters, oil filters, spark plugs, and engine consumables for common workshop and trade-grade generators.

Product pages list rated output (in kVA, kW, or watts), continuous and peak power ratings (peak load is normally 20-30% above continuous), engine type (petrol or diesel), tank capacity and run-time at typical load, output sockets (16A, 32A, 110V CEE, 230V single-phase), and weight.

For replacement parts, the matching dimension is the original part number or the generator model code. Trade pricing on multi-unit and fleet-fit-out orders is available; contact the team via WhatsApp 07754288583.
