Why Availability Matters When You Buy a Backup Generator
Most people look for a backup generator after an outage, a near miss or an insurance review. At that point, a long lead time is a real cost. A supplier that holds physical stock can shorten the wait between enquiry and delivery, and can often supply a set to a specification you can check in person before it ships.
That is why we hold a large range of generators in stock in the UK. Lead times vary by model, and some sets are marked as available to order, so check the stock list or ask our team what is ready now.

How to Choose the Right Backup Generator Before You Order
Getting the specification right matters as much as getting the generator quickly. Work through four decisions before you request a quote.
Step 1: Know Your Load
List the equipment you need to keep running during an outage, with the running power of each item and the starting power of anything with a motor. Motors, compressors and pumps draw much more when starting than when running, and that affects the size you need. Allow headroom for growth, and avoid sizing the set to the exact figure.
Step 2: Choose Single Phase or Three Phase
Most homes and small premises use a single phase supply, and single phase generators suit them. Larger commercial and industrial sites with three phase equipment usually need a three phase generator. If your site is mixed, tell us so we can specify the right output.
Step 3: Decide Between Silent and Open
Silent generators have an acoustic canopy that reduces noise and protects the set from the weather. They suit outdoor and urban installations. Open generators are designed for plant rooms and controlled environments where the building provides protection.
Step 4: Plan for Automatic Start
A true standby generator starts by itself when the mains supply fails. This normally needs an automatic transfer switch or an automatic mains failure (AMF) controller. If nobody will be on site during an outage, automatic operation is worth specifying from the start.
Backup Generators in the Real World
Our customers use standby sets in a wide range of settings. A few examples from our case studies:
- A 38 kVA Cummins generator for a groundwork contractor's workshop in Buckinghamshire
- Three 110 kVA Cummins generators for an automated packaging machinery manufacturer in Wales
- A 20 kVA Pramac generator for a new EV rapid charging hub in Manchester
- A 28 kVA Cummins generator for whole-house backup at a rural home in Devon

Can I see what is in stock before I call?
Yes. Our stock list shows what is available. Some models are marked as available to order, so ask us about timing.

Yes. We have a range of generators for homes with options suited to residential backup power.
Do you export?
Yes. We supply generators for export worldwide, including completed projects in Libya and the UAE.
