Priced per server.
No contract and no per-alert charges. There is a one-off setup fee, because the first week only works if someone has learned what your server normally does — pay for a year and we waive it, along with two months of the subscription.
Pay for a year and 2 months are free — and setup is waived.

Setting up
Charged once, at the start. It is not a charge for installing the agent — that is one line you paste in, and it takes a minute.
A server you already have
£75
one-off
We learn what the machine does, what normal looks like on it, and tune the alerts to match — so the first week tells you something useful instead of crying wolf.
A new server, built from scratch
£125
one-off
We specify the machine, build it to the hardened standard with the same version-controlled recipe every time, and then do all of the tuning above.
What this is instead of
Managed server administration in the UK is typically £150–£300 per server per month once monitoring, patching and someone to call are included. At the other end, a monitoring tool costs less than Onserva but stops at telling you a number has gone red — you are still the one who has to know what it means and what to do at two in the morning.
Onserva gives you the explanation and the fix that a managed service gives you, for roughly a third of the price, because the parts a machine can do well are done by one. What you are not paying for is somebody reading a graph at three in the morning.
Questions people actually ask
- Is there a contract?
- No. Monthly billing stops at the end of any month. An annual plan is paid a year in advance and runs to the end of that year — that is what the two free months are in exchange for.
- What is the setup fee actually for?
- It is not for installing the agent — that is one command you paste in, and it takes about a minute. It pays for the part a machine cannot do: finding out what your server is actually for, what a busy Tuesday looks like on it, which services matter, and setting the thresholds accordingly. Skip that and your first week is a stream of alerts about nothing, which is how people learn to ignore alerts. It is £75 for a server you already have, £125 for one we build from scratch, and nothing at all if you pay annually.
- What counts as a server?
- One machine running the agent — a VPS, a dedicated box, or a cloud instance. Websites and applications on the same machine are not counted separately.
- What if a fix goes wrong?
- Every action comes from a short list that has been tested on real machines beforehand, and nothing runs until you press Authorise. What was done, when, and what the server said back is recorded in a log that cannot be edited afterwards — including by us.
- Do you need access to my server?
- Only when you ask us to set a new one up, and only for that one job — the credentials you hand over are destroyed the moment the work starts, and the recipe removes that way in permanently at the end. Day to day, Onserva has no way into your machine at all.
- Can I try it on one server first?
- That is usually the right way to start. Put it on the machine you worry about most and see what it tells you.
