Something like this TD......?

http://www.ebuyer.com/product/65711

which seems to be more for business use,

or  for home use

http://www.amazon.co.uk/APC-Back-UPS-700VA-United-Kingdom/dp/B000GQMH9U

Some customer reviews on Amazon as well.

APC seem to be a good company for such a product.On their website you can configure a product to suit your needs.

Sorry if I'm telling you what you already know TD, but do be aware that a UPS will only give you a very few minutes running after the mains fails. You need to install the software which comes with it, which will shut down the PC safely a short time after the mains interruption. So there may not be much point in powering the router from it, unless you get very short mains failures which are restored within a minute or so. By the same token, the only purpose in powering the monitor from it would be to give you a minute to save any data which you're working on; only useful if you're actually sitting at the PC at the time.

I have used APC for many years but, as Roseway quite correctly points out, they are really only to enable a graceful shutdown to protect your work-in-progress.

Also, the internal lead-acid battery will need replacing after about 5 years at a cost not too different to that of a new total unit.

We live in an area that suffers brown-outs and short loss of power and I have found mine invaluable when working on a desktop machine.  The laptop, of course, has its own UPS, called a battery!

Thank you all for your comments and advices.

@unkyUb....thanks for the linkys, will have a look at these. The ACP brand does seem to have a good reputation.

@ roseway...Thank you, and I do understand the points you make.
My problem here with regard to power outages is that whilst major, longer term cuts are as rare as anywhere else we do get plagued in certain weather conditions with cuts lasting perhaps two or three seconds........and a ups would be invaluable in that circumstance, as camallison has noted.

@ camallison...thank you for the input...had not realised about the depreciation and demise of the battery ( mind you, at my age I do not anticipate being in a position to buy again in five years time.. )
I must confess that my concern about uncontrolled shutdown is not so much saving work-in-progress as avoiding physical damage to the hard drives.

Can you advise further, please.
Any ups I have is going to have to be placed on, under or about my desk on which lives my wee router (wired to PC).........under normal conditions and with the mains power on and feeding all the components, does the presence of a lead-acid battery in close proximity to a router cause that router any problem ?  
Also, would that same battery cause interfereance on my TFT monitor ?

Thank you all again.

[camallison]

No problems at all - the battery is a sealed type and won't cause any interference - in fact, it smooths out the bumps in the supply.  Mine is on the floor under the desk where Maisie keeps it company.  A good purchase considering your (agricultural) supply - that's how the supply company describes ours, so that they don't need to guarantee any uptime.

[Reminds me of when I was working in the Irvine area installing the high voltage switching gear to the (then) new Glaxo Smith Kline plant.  The electricity supplier (SSEB) was foolish to guarantee them no more than 1 total outage in 5 years since duplicate supplies had been laid over from the Lesmahagow area.  Guess what - the first winter we had 15 outages and so we asked SSEB if that meant we wouldn't have any more for the next umpteen years!]

The battery itself won't cause any issues to the router or monitor.

If there were to be any issues it would most likely be from the inverter (converts battery DC power to AC power), or the rectifier (converts AC power to DC power to charge the battery), however I doubt you would have any problems in normal operation - only if a fault arises with it.

That APC unit does look like a decent bit of kit.

Thank you all for your further advices and comments....off to spend some money..

My psu is a 450 volt job, and I would need at least three sockets on a ups.....PC, monitor and router ( the printers and scanner can go hang)

450 volt  what have you got in your computer Thermionic valves ? that need 450v HT and 6.3v for the heaters.

[oldfogy]

I took it that he really meant 450 Watt, but forgot to mention it earlier.

Hi all,

what have you got in your computer Thermionic valves?

Absolutely - A-Open used to do a motherboard with a valve audio amplifier:
