Is the garage attached to the house?
If it is attached to the house and you have spare room in your consumer unit then run a 2.5mm ring with a 32amp 32ma rcb for the power sockets, freezers, etc.
Run another 1.5 or 1mm radial circuit for the strip lights- an ordinary 6amp mcb would do on that.
If the garage is seperate I'd run an armoured cable to it from again a 32amp 32ma rcb in your house condumer unit. Put a smaller consumer unit in the garage (with the armoured canle to the isolating/main switch. From this smaller condumer unit run your ring and lights circuits as above.

Hi - just saw this thread, my OH is looking into abandoning the NHS and retraining as an electrician - he's been looking at some of the providers but I don't think he has seen the OLCI. Could you possibly PM me with the course costs, please?

After a hard week doing the Inspection and Testing module i heard this pm that i've passed all the exams and practicals. There's still Solar installations and electric boilers to do but it means I can now apply to join a 'competant person' scheme and get ready to finally earn some money as a proper sparky.
Too nackered to jump up and down but when i recover some serious celebration is called for.
If anyone needs a free range organic electrician, you know who to call...

I am joining the NICEIC 'competant person' scheme to be a qualified domestic installer. To do this they want to see 2 pieces of work that you have done (they come and inspect 2 new ones every year to see you are obeying the regs).
I went for a consumer unit replacement in our house and ordered a brand new split thing - it has 2 sets of 5 circuit breakers, each controlled by a RCD switch. Also it has 3 ordinary mcbs with no RCD.
So I took out the old CU and put in the new.
When it came to switch on every circuit except one tripped the RCDs!
Luckily I can temporaily link the circuits to the no-RCD protected mcbs so at least we can have some power. It has after all been operating fault free for years.
When I tested for continuity (to check all the wires are joined up) all were fine. But the IR test (test that the insulation is sound) failed all the circuits bar one.
Never mind it's a good thing for me to try and figure out and better I do it in my own home rather than at a customer's.
I tracked down the faulty line on the socket circuit, so thought I'd lift the floor boards and locate the exact location of the fault. What a nightmare!

Whoever re-wired the house was not a tidy person and worse they laid wires under the first floor in a single notch barely an inch deep - no trouble at all to bash a screw or nail through them if you felt like it. And there are 12 wires (plus 2 for the telephone) all squeezed together as they cross each joist. They were also run laying on the central heating water pipes.
The pic shows them after I separated them a little!

So I'm going to have to pull up a lot of wires and re-route through several holes in the joists - to spread them out.
Having found the fault I replaced the damaged wire and then connected the ring via a RCD - at least it does not trip now.
Only 6 more circuits to go. I can see this is going to end up taking a very long time...

I am sure you know but just in case.

A really common reason for the rcd to trip in cases like this is due to the neutral being wired back to the wrong rcd on the split board or for some one to have tapped into a neutral mainly to add an extra light & when a split board is fitted the live & neutral end up on different rcd's.
