Regretfully it is not possible to give an opinion, and certainly not advice based on the details given in your OP. As Gizmonster says it all depends personnal circumstances. There are so many questions that need resolution first. Are you trying to access a Defined Benefit Pension pot or a Defined Contribution pot?
Why do you want to release funds that could make your retirement much more comfortable? Are you trying to do Draw-Down? Is the Pension Pot trivial or substantial? Were you aware that if you take a lump sum, which is a proprtion of the total pot, then only 25% of that is tax-free, the rest is taxed at your notional rate. You cannot take 25% of the total pot and assume all of it will be tax free. So if your Pension pot is now worth £400,000.00, if you take £100,000.00 now, only £25,000.00 is tax free this time. Although the residue of the fund may reain invested, every time you take a lump sum only 25% of that will be tax free.
Be very careful with releasing funds from a Pension Pot. Professional advice is still not neccessarily the best advice.
