The system only matters on the day it has to work.
If your property makes its own power, there is no network operator to ring and no one else whose job it is to notice a problem. Annual generator servicing, repairs and replacement — across Scotland and nationwide, including equipment we didn't install.

When you generate your own power, nobody else is watching it
On the grid, someone else owns the problem. Your supply is somebody's job, faults get noticed by a network operator, and a power cut ends when an engineer you never meet fixes something you never see.
Off-grid, all of that is yours. There is no operator monitoring your supply, no automatic fault reporting, and nobody whose responsibility it is to spot that something has quietly started to fail. The only warning you get is the one you go looking for.
That is what makes servicing different for remote and off-grid properties. It isn't routine maintenance on a convenience — it's the only mechanism that tells you whether the thing your house depends on is still up to the job.
Backup equipment fails silently. A standby generator spends nearly all its life switched off, which is precisely why a developing fault goes unnoticed. Nothing announces that it has stopped being reliable. You find out at the exact moment you needed it to work.
The pattern we see repeatedly: a system installed properly years ago, never looked at since, on a site where getting someone out at short notice is difficult and expensive. Nothing was neglected deliberately. There was simply never a prompt.
Three things we do
Annual Generator Servicing Contracts
Scheduled annual servicing for domestic and off-grid generators — so the visit happens because it's booked, not because someone remembered.
Domestic standby sets and off-grid primary sets get looked at differently, because they're doing different jobs. A standby generator needs to be certain to start after months of sitting idle. A primary set is running real hours and wearing accordingly. Same discipline, different emphasis.
We service equipment we didn't install. That includes legacy plant, obsolete models, and machines that other firms have declined to quote on. If you've taken on a property and have no idea what's sitting in the outbuilding, that's a normal starting point — not an awkward one.
Generator Repairs
Generators that won't start, won't hold load, or have simply stopped being trusted.
The first job is an honest diagnosis, because "it doesn't work" covers everything from a fuel problem to a failed alternator, and those are very different conversations. A non-runner is far more often a fuel, starting or control fault than a dead engine — which means repair is frequently the sensible answer, at a fraction of replacement cost.
Where a set genuinely is beyond economic repair, we'll say so plainly and talk you through generator replacement — sized to what you actually need, not the biggest set we can sell. What we won't do is push a replacement because it's the easier sale.
Generator Replacement
When a set is genuinely beyond economic repair, we'll say so plainly and quote a replacement sized to the loads that actually matter — not the biggest set we can sell, and not a like-for-like swap just because it's the easy answer.
Because we install as well as service, a replacement is handled end to end: the old set removed, the new one sized, installed, commissioned under load and handed over. See generator installation for how that works.
Most of the time it doesn't come to that. A non-runner is far more often a fuel, starting or control fault than a dead engine, so a repair is usually the sensible answer first.
What a service visit includes
Exact scope depends on the equipment, but a generator service visit covers:
- Engine inspection — fluids, filters, belts, general condition and wear against what that set should look like at its age and hours
- Starting and control systems — tested deliberately, never taken on trust, since nothing else matters if the set won't fire
- Running test under load, not just a start-up on no load
- Fuel system, tank condition and, where fitted, long-run supply arrangements
- Electrical connections, changeover or transfer switch operation, and the distribution the set feeds
- A clear written account of condition, anything developing, and what we'd recommend doing about it
The last point matters as much as the practical work. You should finish a service visit knowing more about your system than you did before — not just holding an invoice.
We service what we didn't install — including genuinely old plant.
Keeping a Classic Lister Running
Decades-old plant, an obsolete auto-start arrangement, no parts catalogue and nobody to escalate to. We hold it on a yearly schedule and give it the same rigour a new installation would get — because the estate's power depends on it, and that doesn't change with the date on the plate.

A site's only power source arrived dead. Repaired, fully serviced, and modernised with remote start and monitoring rather than replaced.

An 8kVA set sized to exactly what the customer asked for, with automatic transfer so it starts itself — reliable backup on a real budget.
