# Generator Servicing Cost

> Generator servicing near me: the cost drivers behind every quote, why no statutory service interval exists, and free quotes from local providers.

## Key facts

- There is no statutory service interval for a standby generator in the UK: PUWER requires work equipment to be maintained in an efficient state, in efficient working order and in good repair, and leaves the frequency to the manufacturer's schedule and to risk assessment (HSE, 2026).
- HSE states that the need for inspection and inspection frequencies should be determined through risk assessment, taking account of the manufacturer's recommendations and the conditions the equipment is exposed to.
- Load bank testing exists because off-load running proves a standby set will start, not that it will carry its rated load; it is a separate purchase from a routine service.
- Stored diesel degrades, so fuel sampling and, where needed, polishing or tank cleaning are a distinct line item on standby generator maintenance rather than part of an engine service.
- In England and Wales the medium combustion plant regime applies to plant of 1MWth or more and less than 50MWth, and the specified generator regime applies to generators up to 50MWth, with exclusions in both cases (gov.uk, 2026).

## Data

- What sets the price of a generator service, 2026. Methodology: This is a cost-driver table, not a price list. It is compiled from the way standby generator service work is scoped in the UK in 2026: the set, the service content, the testing regime, the fuel system and the site. We publish no average price because there is no checkable UK dataset of generator service prices, and an unverifiable average is worse than none. The regulatory rows are sourced to HSE guidance on PUWER and to gov.uk guidance on medium combustion plant and specified generators, linked below. For a real number, use the quote form.
