How much to charge for an EICR

[SparkyChick]

I suggest you use Google and run a search for "internet troll", but just in case you're not....

As @davesparks has stated Z is used to refer to impedance.

Zs is the earth fault loop impedance at a point on a given circuit. Ze is the external earth fault loop impedance (measure at the origin of the installation).

Zs = Ze + (R1 + R2)

Where R1 is the resistance of the line conductor from the consumer unit to a given point on a circuit and R2 is the resistance of the CPC from the consumer unit to that same point on the circuit.

We are obliged to ensure Zs is within specified limits to ensure the protective devices operate correctly within the required timescales. And yes, if you breach Zs and you have an RCD present you can use that as the fall back for fault protection as the maximum Zs permissible is much higher than that for MCBs and RCBOs.

And to clarify the difference... r1 (as opposed to R1) is the end to end continuity of a ring final circuit line conductor (like rn is end to end for the neutral, r2 is end to end for the CPC). Using those you can gain some insight as to whether your RFC is connected as expected as R1+R2 should be approximately (r1+r2)/4. Likewise R1+Rn should be approximately (r1+rn)/4.

As stated above it a free market, you can Charge what you like, but....
If you've not done them before its good Patrice to start, but you really should make sure your confident in doing them, there is quite a bit of responsibility here your taking on/ Liability, your making a profession statement about an electrical installation in comparison to the wiring Regulations. you should also check out GN3 as it will help you a lot with the Testing. for example you don't want to do the R1 + R2 on the Lighting circuit as this means you will have to remove all the fitting. Now in some simple house hold installation that might be fine but in reality its a nightmare, modern houses Can have loads spot lights, wall lights under cupboard lights, blah blah blah. you get the idea, A 30m length of earth cable 1.5 or a wonder lead if your posh and do the R2 read supported by Zs at the Extremity of the circuit, if you can find it.

Price Wise, as a guild Which I think is reasonable and a fair price for domestic house hold, a small flat 4-6 circuits , £100- £150 if its a 3 bed house£150- £200 large hosue £200 plus, the paper work will take you a few hours to fill out, depending on whats wrong and I have always had to wright a report with them, you don 't make any money per-say out of EICR but they sometimes lead to work and I find they are a good tool in building trust with the customer if you know what your talking about.

Hope that Helps

I thankyou very much for that information it is most useful in my understanding of the problem. It is not my intention to carry out any Trolling I just need the answers to my questions which I think is what this site is about

^^ you need to answer questions too. On. Another thread you claim to only earn £8k per year.. Which is clearly not accurate for a full time spark

I think I said that my take home pay was 8000, which is what I end up with after all my business expenses are paid eg Accountants fees, van costs,diesel,insurance in its various forms and all the rest, just checking to see if I'm being correct in what I say...Looking at accounts and on a turn over of 26,144 my costs were 19,105 leaving 7039 so a little under 8000

So any advice as to where I'm going wrong will be gratefully received because clearly I am doing something incorrectly ..many thanks

How about starting another thread listing your expenses in detail and see if anyone can suggest where savings could be made. On the face of it, your expenses seem high in relation to turnover.

Edit: On the other hand, if you're managing to include your mortgage or rent as a 'business expense', then maybe your expenses are reasonable!

Costs of £19k, really..... Take home just over £7k...... Doesn't add up

Yes I was of the opinion that these costs may be high, but talking to others that I work with they seem to be inline with what they pay, alas no mortgage only rent , others have suggested increasing turnover in some way. Looking at the costs, fuel seems to make up a fair chunk at nearly 4000, and van lease of 2796 per year. I'm not sure if this is in line with what other people expect to pay?

Accountant says that I must pay a sum of money for the use of a room as I may get stung for business rates ....don't want that

 

[Octopus]

So £19K total expenses , less £4K fuel (which sounds high), less £2796 van equals £12204 of "other costs" - really?

Last year, my total business expenses (I own my vehicle outright) came to £6916 all in (excluding income tax and NI)... as Handsparks suggested, maybe you should start another thread as something sounds very wrong to me

 

[Mumfi]

Ok so it seems that I'm paying too much for something, without betraying any commercial confidences can I as if you turnover is more or less than mine, many thanks

 

[Mumfi]

sorry ask

 

[Octopus]

My turn over last year was just over £70K

Wow, I'm very puzzled now at my costs
