With regard to private care, if you live outside SE England you are out of luck. There are no consultant led private maternity facilities outside the SE. None. That means you can only get a private ELCS in the SE. (And people wonder why the Portland has such a high cs rate compared to the national average...)
Which means you either will need to find someway of getting around the geographical problem or face the NHS lottery.
From what I've seen on here, some people have been able to get one without question, others have had a distressing and difficult time after being initially refused one before they eventually get the request granted and in a small number of cases are simply unable to get one under the NHS. Policy differs massively from hospital to hospital and between consultants.
If you are budgeting to go private, the Portland is definitely the most expensive option out there. There are private wards at several NHS hospitals. Watch out for what fees include/don't include. Antenatal care and consultant appointments aren't always. And if there are complications, for example if your baby needs SCBU, you may also face additional fees. I think the cheapest options start at about the £8000 mark for a problem free ELCS but depending on where you go or what you need you may be lucky to have change out of £15,000.
I actually disagree with HereIGo approach. I think such is the mood in many hospitals that if you go in with that type of attitude, there is a tendency to think if you aren't taking it seriously that you are easy to give the brush off. From what I've seen on MN, the most successful way to go, is armed with your facts so you can appear that you are taking it seriously, take your partner and get him to back you up... and if all else fails cry, ask for a referral to another consultant or ask to speak to peri-natal mental health midwife.
The "maternal request" thing is an odd term and the NICE guidelines are aimed more at the mental health aspect of a request than one for lifestyle. The trouble is hospital policy seems to be taking the attitude that maternal requests are about lifestyle and connivence when the reality is very different. This is why, if you are serious, pushing this aspect of your request is essential. It makes it a lot more difficult for them to refuse for a variety of reasons.
I do think Shagmund's point about the number of children you want, is one you do need to seriously consider. There is nothing in the NICE guidance about this which is unfortunate and to an extent is effectively glossing over a very important point - it could mean that some women are deciding to have an ELCS without crucial information. Also the NICE guidance points out that no research on the long term health effects on mother or baby from an ELCS just hasn't been done. This isn't about having a VB v CS debate. Its about helping you to decide whats the best option in your personal circumstances and what the consequences of any decision you make might be - an informed decision rather than a biased opinion.
If you look at the NICE guidance on the risk of death for a planned ELCS and a planned VB they are very similar - they were unable to say one was more risky - mainly due to such a small number of maternal deaths in the UK being so small that the data was unreliable. Childbirth in the UK is very safe for women. But have a GOOD look at the risk table as different complications are more likely for each planned mode of delivery. For example a hysterectomy is a slightly more likely with a ELCS (though the absolute risk appears to remain low), and there is a slight increased risk to your baby needing SCBU care with an ELCS. These might be something you consider unacceptable and make you reconsider your options. I don't know.
A lot of advance/guidance being given out there seems to be painting a very different picture from the NICE guidance. Bizarrely some MNetters have found a VB being forced down their throats and the CS risks pushed heavily by HCP - until the request is granted when an ELCS amazingly becomes very safe and nothing to worry about! My point is here, is not to push you down one route or another, but to make sure you are prepared to do your homework and question and challenge what you are being told in order to get your views listened to and your questions taken seriously. There are too many HCP who have their own agendas and unfortunately, in the case of maternal request ELCS, it seems its often at the expense of patients.
I also think its very important to consider your fear and whether you could benefit from counselling and potentially consider an VB and not discount the idea completely if you possibly can. What is it you are afraid of and are there ways you think you could minimise problems or be more comfortable with a VB. A doula, hypno-birthing, an independent midwife, a homebirth, cognitive therapy amongst others are options.
If thats a total nonstarter as your fear is too strong, then thats fair enough, but honestly none of us here know that, and it would be unwise for anyone here to push you too heavily to an ELCS without suggesting potential alternatives. We simply don't know the extent and severity of your fear.
