There are lost of them but they all are designed for controlling 240 ac with a voltage range starting at about 75v ac
My application requires switching of between 1 and 5 volts. Such an SSR exists - RS components have several ... so it is possible
Does anyone know either
a. a Uk based manufacturer who i could contact and ask them ( for a higher fee i am sure) to make up their standard board, but to substitute different SSRs
b. someone who produces low load voltage SSR boards
PS - I have considered mechanical relays but this introduces moving parts and I would prefer to avoid them if possible.
Terry form Yourduino stocks a number od SSR boards and FET boards. Any of them should suit, depending on how many channels you need. The rated voltages are a maximum and they should have no problem switching lower voltages. RELAYS and POWER CONTROL
I am switching a very low voltage ( 1-5v) low current - not measured but 20ma is probably the right ball park.
As such the SSR chosen need to be able to switch that range.
RS have them so the component is not the issue - simply that i need a board populated with them - hence if there is a UK manufacturer i can ask if they are prepared to swap out the components for me on build.

Can you please post a link to the RS part you mean.
No main manufacturer will be interested in doing what you want, they typically work on minimum order values or order quantities of 10k units.
You could approach a local electronics company and request them to modify your board or produce a bespoke board.
However still cannot quiet understand why you are going for a SSR when a simple transistor will switch your load, but as said, must be missing some key point ?
The circuit being switched is the control system of a boat. The action is to place a resistance over a potentiometer to force the system into putting the vessels into forward or reverse based on the control input form the arduino.
The reasons for a SSR as opposed to a transistor is that the circuits must be isolated - which the SSR does for me.
A mechanical really will of course work as well, but i am seeking to eliminate moving parts.

How many SSRs per board are you considering and how many boards per order?
Would you not be needing other parts of the whole project mounting on that board otherwise you have a lot of interconnects ?

I am looking for ideally 10 per board and if this was a custom component I would then add 4 trimming potentiometers to the board to eliminate the need for these to be mounted elsewhere.
I would look to order 1 -2 ( with the attendant costs that would involve) sand after that in batches of 50
Well imho you would first be better to complete a prototpe of the whole project hand wired, either by connectors or soldering.
Then with your software fully test its function to be 100% sure it both works and fullfills your actual needs.
Only then so you want to look at having a board manufactured, otherwise you will only find manking one now will only result in reworks.
You can of course design your own pcb and have them produced by mail order, typically from China or a local UK pcb maker.
Usually a locally electronics company will do it all for you, its just a case of knowing someone local to you with a good reputation for helping a developer like yourself.
I'm not in the smoke or have contacts there these days, perhaps some other member may, or try yellow pages etc.
