Just had a quote to add another system alongside my existing setup (2014 install, 16x250w, 3 roofs, SolarEdge, 4kWp, FIT)

Quote comprises 

3.6kWp (8x450w) over 3 roofs (so lots of scaffolding)

SolarEdge SE3000H inverter

GivEnergy 5.2kWh battery

All fixings etc, new CU if reqd

Cost £12200

Agree with comments from others - based on quotes I've seen as recently as this month, you should be paying no more than £5500 installed for 8 SHARP 410W Black panels and the SE 3000 inverter. 20 year extended warranty included.

I'm surprised to see a quote with a GivEnergy battery married to a SE inverter (high on my recommended list btw) - I didn't know they were compatible without a controller. If you want an external battery, the SE 10kW battery would be an extra £8K installed but I'd suggest crunching the numbers to see if a battery makes sense (vs. exporting to Flux).

It's likely the quote is missing some detail in relation to the battery & likely to include a Givenergy AC inverter which will bump up the price a bit as well.

Certainly not mentioned on the quote anywhere.

The Givenergy batteries won't work without their dedicated inverters, so something isn't quoted correctly or missing.

Ours was an awkward install, 2 roofs at different levels, slate, and cost c£7.5k for 4.7kw with a cheaper inverter.

it wasn’t the cheapest quote but cheapest often does not mean best- reviews, responsiveness, what will they do when something goes wrong etc.

Seems a wee bit expensive at first glance, definitely worth getting other quotes. One thing that jumps out is why aren't you considering a Solaredge Home Battery to go with the Solaredge system?

Re: SolarEdge battery, was advised that they only do a 10kWh option (might have misheard that at the time) and wanted something I could expand if required, ideally myself, which pretty sure can’t be done with SE.
Really struggling to get more quotes, even to get a reply to an enquiry!  

With the Solaredge Home Battery you can add batteries no problem. Each inverter can have 3 batteries with a maximum over 3 inverters would allow 9 batteries in total. So in response to your comment, get one battery and if you want more just get another, the physical connection is just a pair of cables like these.

I think the cost of the SE batteries is the issue at the moment. Not sure that I’m gonna need a 10kWh battery to start so prefer the option of being able to start smaller and expand as and when needs arise / funds available etc.

Thanks everyone for the input. Got a survey going ahead on the 7th at a major saving. Neighbour is also getting a survey on same day, so all good.

The only thing I'll add is - get the biggest system you can afford and cover your roof as much as possible. 
The only regret we all have had is not putting enough panels up, adding at a later date is really expensive

Yeah, your regret exactly mirrors mine. I think back in 2014 I would have had issues around going above 4kWp with the DNO. My initial quote to upgrade would have agreed with your “..later date is really expensive” comment but the revised quote, thanks to input from here, isn’t really that different and includes a battery so I’m well chuffed.

Have you tried ECH? They are based in Fareham and did my install - reasonably priced compared to the other quotes that I had and tend to use ladders or towers (so cheaper than 3 sides of scaffolding which could add a couple of thousand to the price). I don't know if they do Solar Edge stuff though - I just had cheaper Chinese panels (3.2KW) and a Solis inverter and AC3.0/Giv Energy battery (8.2kw) - came to about £8000 last year, but I know prices have gone up A LOT!
