DNO curve ball - Section 37?

[New to this]

Hi, not sure which forum was the right one so opted for this one.  Our new build is in the garden of our existing bungalow, the last property on a low voltage line. 
Despite over 2 years back and forth with the DNO for quotes for the connection, I've discovered today that they can't do my connection without it going to Parliament (??) to the Secretary of State, under the 1989 Section 37 legislation. The existing bungalow, being the last of the line, and despite having a main electricity line to the pole outside, is not allowed to be followed on by any further build, without said sign off.  Which apparently typically takes about a year.  

 

I am adding this in as an edit - I don't think it's the Sec of State, reading this from the DNO's own website:-

A Section 37 application is a two-part process involving an initial application to the local planning authority followed by an application to the appropriate Ministry:-

Scotland - Scottish Government Energy Consent Unit

England / Wales - The Department for Business, Energy and Industrial Strategy

There are certain circumstances where a supply may be provided to a single customer at less than 33kV without the need to obtain a section 37 Consent. In these situations, it is still necessary to consult with the local planning authority before constructing the line. Where an existing line serving one customer is subsequently required to serve further customers, a retrospective Section 37 Consent will be required.

Section 37 consent can also apply in cases where underground cables are being installed from an existing overhead line, where retrospective Section 37 may be required. Where it is necessary to modify an overhead line, Section 37 may be required or in certain circumstances, works may be carried out under the provisions of the requisite Overhead lines (Exemption) Regulations.

To say I'm reeling is an understatement. I'm desperate to research whatever I can find now about others who've maybe found themselves in this position, did you manage to deal with it, how, costs etc and what on earth can I be trying next!?  

Apparently "the quote team should have spotted this" ... but I can see no advantage in my pressing the red button with the DNO, it won't alter the position I'm in now, nor the timescales to overcome it.

Sounds like loads of PV, battery and generator is required - if you an get mains gas run the generator from that, exhaust heat exchanger, to do the heating while generator is on. And some batteries.

Probably an obvious question that you'll already have looked at, but can power be brought to the plot from a different source/direction?
