Company Pension Cash withdrawal

No. Not until you decide to retire - usually you have to be over 50 to do this.

You can transfer the money to another pension scheme in some circumstances.

Not if they wont answer letters!

Seriously, most pension schemes have a transfer value. It is usually less than your plan is worth but it what you get if you pull out early. Otherwise it is normal to either be paying in, or retired. Most schemes wont allow piecemeal withdrawals. What is allowed, however, depends on the wording of the scheme.

A better option might be to consider borrowing money on the strength of the plan. Many mortgages, for example, use a pension plan to pay off the capital.

DP, please dont take this response as me having a go at you in view of our previous exchange! But I think you are wrong on most points here.

The statement that T/Vs are 'usually' less than they are 'worth' is either confusing (with regard to defined benefit schemes), or misleading (with regard to defined contribution schemes). If it is a money purchase scheme investing in 'with profit' funds then you are right, but otherwise you are are probably wrong.

With regard to what is 'normal' then my understanding is that for most 'pension' plans, then the majority of members are not contributing or taking benefits! They are either early leavers, paid up, or deferred, but of course I accept that this excludes all those who are benefiting from annuities, and you may be including them in your data.

Piecemeal withdrawals are only allowed by special 'income withdrawal' or 'drawdown' schemes which, generally but not exclusively, exclude occupational schemes and only if aged 50+ (in most circs).

With regard to borrowing against the 'pension plan' then, in the absence of any other reason to lend, this is only available if there is sufficient security to repay the debt in any event, such as a legal charge on the home (because lump sum pension benefits can not be assigned), and is not available to anybody in an occupational scheme in any event, and I think it is likely that the OP is in an occupational scheme.
