Amps x Volts means you used 29 plus Watts -
Not far from the 25w standard that most radios state as their output.
VHF in waterside workshop - Can someone suggest a mains power supply unit

It was a Pye Westmintser. I thinbk most are 25w on transmit high power, 1w low

25W is the output power, it will probably be nearer 40W of actual DC power consumed on transmit.
The OP could go and stand in a tender moored just outside his workshop and legally use a ships radio there.

???? VHF is designed to run on the range of voltage found on boats ... that's literally 11v up to 14.8v ..... basically the range your on-board batterys go through and while charging from alternator ...
The only item that then is of concern - the lower voltage will incurr higher amps to maintain the Tx power ... and is why I advocate a 12v 5A PSU ....

Drop OfCom an email or lift the telephone and speak to them.

Which is exactly why I suggest running it on the correct voltage. Most components are rated by current so running them hotter/higher/faster will only shorten their life.
My third link in the post above yours has this item (Nevada PS08) available direct from Nevada for £10 less than the Amazon link you provided. For info in case the OP chooses to go down this route.
Nevada PS-08 - Waters & Stanton

As one cynical Scot to another. Quite right! The usual load of verbal diarrhoea, or should I say literary, Any power supply as mentioned by Refueler will do, forget the fancy expensive gubbins which is totally unnecessary. The important thing is to stay within the law and get the correct radio and licence!!

I don't agree a cheap Chinese PSU intended for something else will do since it will be a very noisy output, both the DC and RFI emissions from the unit. I've watched enough Big Clive on You Tube not to trust any Chinese PSU in my house other than those that came through Apple/Samsung etc QC.
My background is as a radio amateur since age 14, a Marconi radio comms apprenticeship, 20 years in the audio industry etc. Big believer in "you get what you pay for". Including advice on internet forums is worth the amount the poster paid for it

just a thought if you go ahead then a set that can use an external aerial and speaker may be useful but limits portability

Between those Chinese Wall Wart PSUs and the powerline ethernet they totally overpowered the receive side of my Yaesu FT895, S9+ could hear nothing at all, now banned any form of powerline internet in the house.I don't agree a cheap Chinese PSU intended for something else will do since it will be a very noisy output, both the DC and RFI emissions from the unit.

Any half decent 240V 10A PSU with stablised output will power a marine radio all day long.
Anything designed for amateur radio would be ideal.
1W would probably be enough to do most short range communications.
Connect to budget VHF aerial, the height would depend on just how far you need to communicate.
If you want to do it properly OFCOM will allocate you a private channel and then charge you handsomely on each renewal, condition of the licence is your base equipment must be type approved for base use .
The frequency will need to be programmed into your equipment usually only available to dealers.
Those 466 radios are great if you can see the other radio user at the end of the garden and also want to share your private conversations with anybody and everybody within range.
Old enough to remember ordering Xtals for marine radio.

Well ... you should know !!!
Trouble is I have a bank of such Chinese PSU's powering many delicate and sensitive items ... radios, Lithium Chargers, remote cameras, loads of gear that TBH outguns a boat VHF !!
I suggest to you that vast majority of PSU's whether internal or external are produced in China ... regardless of brand label.
I have a couple of HP Computer power banks ... capable of 1300W each ... guess what ... Chinese !!

In the boat I have a 240-12 v transformer - try Surom12v 30a Dc on Amazon- cost about £22. In the Workshop I use a variable voltage transformer - try searching R-SPS3010- gives more options on voltage and amperage- price £40-60 depending on exactly what you want.
