Any sane way to invest in both funds and stocks with UK ISA?
You could use a stock-only ISA and invest in Exchange Traded Funds (ETFs). ETFs are managed mutual funds that trade on open exchanges in the same manner as stocks. This changes the specific fund options you have open to you, but there are so many ETFs at this point that any sector you want to invest in is almost certainly represented. "A lot of  ISA's allow both shares and funds as well as gilts, Hargreaves Lansdown  comes to mind as does the Alliance Trust. Some penalise (charging wise) securities vs UT (unit trusts)  funds but in that case just go for a low cost IT (Investment Trust)  ISA and hold individual shares as well as pooled investments in the Big IT's. I think you might have to be an ""approved investor"" to buy gilts."
If you want to invest in the stock market, whether over a shorter period of 1 to 2 years or over a longer period of 10 or 20 years or longer you need to take some precautions and have a written investment plan with a risk management strategy incorporated in your plan. Others have said that 1 to 2 years is too short to invest in the stock market as the stock market can have a correction and fall by 50%. But it doesn't matter if you invest for 1 year or if you invest for 50 years, the stock market can still fall by 50% just before you plan to withdraw your funds. What you need to figure out is a way to get out before the market falls by 40% to 50%. A simple way to do this is to use technical indicators to warn you when a market trend is starting to change and that it is time to get out of the market. Two simple indicators you can use on a market index are the Rate of Change (ROC) indicator and the 100 week Moving Average (MA). Below is a 10 year weekly chart of the S&P500 with these two indicators charted. They show good times to get into the market and good times to get out.  If you are using the 100 week MA you would buy in when the price crosses above the MA line and sell when the price crosses below the MA line. If you are using the ROC indicator you would buy in when the ROC indicator crosses above the zero line and sell when the ROC indicator crosses below the zero line. So your investment plan could be to buy an Index ETF representing the S&P500 when the ROC moves above zero and sell when it crosses below zero. You can also place a trailing stop loss of 10% to protect you in case of a sudden fall over a couple of days. You can manage your investments in as little as 10 minutes per week by checking the chart once per week and adjusting your stop loss order.  If you want to progressively add to your investment each month you could check the charts and only add any new funds if both the ROC is above zero and sloping upwards. Another option for adding new funds could be if the price is above the MA and moving further away from the MA. All these rules should be incorporated into your investment plan so that you are not basing your decisions based on emotions. There are many other Technical Analysis Indicators you could also learn about to make better educated decisions about your stock market investments. However, what I have provided here is enough for anyone to test over different indexes and time frames and do their own paper trading on to gain some confidence before placing any real money on the table. In a word, no. Diversification is the first rule of investing.  Your plan has poor diversification because it ignores most of the economy (large cap stocks).  This means for the expected return your portfolio would get, you would bear an unnecessarily large amount of risk.  Large cap and small cap stocks take turns outperforming each other.  If you hold both, you have a safer portfolio because one will perform well while the other performs poorly.  You will also likely want some exposure to the bond market. A simple and diversified portfolio would be a total market index fund and a total bond market fund.  Something like 60% in the equity and 40% in the bonds would be reasonable.  You may also want international exposure and maybe exposure to real estate via a REIT fund. You have expressed some risk-aversion in your post.  The way to handle that is to take some of your money and keep it in your cash account and the rest into the diversified portfolio. Remember, when people add more and more asset classes (large cap, international, bonds, etc.) they are not increasing the risk of their portfolio, they are reducing it via diversification.  The way to reduce it even more (after you have diversified) is to keep a larger proportion of it in a savings account or other guaranteed investment. BTW, your P2P lender investment seems like a great idea to me, but 60% of your money in it sounds like a lot. would you say it's advisable to keep some of cash savings in a foreign currency? This is primarily opinion based.  Given that we live in a world rife with geopolitical risks such as Brexit and potential EU breakup There is no way to predict what will happen in such large events. For example if one keeps funds outside on UK in say Germany in Euro's. The UK may bring in a regulation and clamp down all funds held outside of UK as belonging to Government or tax these at 90% or anything absurd that negates the purpose of keeping funds outside. There are example of developing / under developed economics putting absurd capital controls. Whether UK will do or not is a speculation. If you are going to spend your live in a country, it is best to invest in country. As normal diversification, you can look at keep a small amount invested outside of country. You can't actually transfer shares directly unless they were obtained as part of an employee share scheme - see the answers to questions 19 and 20 on this page: http://www.hmrc.gov.uk/isa/faqs.htm#19 Q. Can I put shares from my employee share scheme into my ISA? A. You can transfer any shares you get from into a stocks and shares component of an ISA without having to pay   Capital Gains Tax - provided your ISA manager agrees to take them. The   value of the shares at the date of transfer counts towards the annual   limit. This means you can transfer up to £11,520 worth of shares in the tax   year 2013-14 (assuming that you make no other subscriptions to ISAs,   in those years). You must transfer the shares within 90 days from the day they cease to   be subject to the Plan, or (for approved SAYE share option schemes) 90   days of the exercise of option date. Your employer should be able to   tell you more. Q. Can I put windfall or inherited shares in my ISA? A. No. You can only transfer shares you own into an ISA if they have   come from an employee share scheme. Otherwise, the ISA manager must   purchase shares on the open market. The situation is the same if you have shares that you have inherited.   You are not able to transfer them into an ISA. Your main choices are ISAs and property. You can put over £15,000 per year into an ISA, which means over £450,000 by the time you retire, not allowing for growth in your ISA investments. But if you're paying rent, and worried about being able to pay rent when you retire, the obvious choice is to buy a flat now on a thirty-year mortgage so that you can stop paying rent and the mortgage will be paid off by the time you retire. There is no country tag, so I will answer the question generally. Is it possible...? Yes, it's possible and common. Is it wise? Ask Barings Bank whether it's a good idea to allow speculative investing. An ISA is a much simpler thing than I suspect you think it is. It is a wrapper or envelope, and the point of it is that HMRC does not care what happens inside the envelope, or even about extractions of funds from the envelope; they only care about insertions of funds into the envelope. It is these insertions that are limited to £15k in a tax year; what happens to the funds once they're inside the envelope is your own business.  Some diagrams: Initial investment of £10k. This is an insertion into the envelope and so counts against your £15k/tax year limit.                 +---------ISA-------+ ----- £10k --------->              |                +-------------------+  So now you have this:                 +---------ISA-------+                |  £10k of cash     |                +-------------------+  Buy fund:                 +---------ISA-------+                |    £10k of ABC    |                +-------------------+  Fund appreciates.

This is an extraction from the envelope; HMRC don't care.                 +---------ISA-------+ <---- £13k ---------               |                +-------------------+  No capital gains liability, you don't even have to put this on your tax return (if applicable) - your £10k became £13k inside an ISA envelope, so HMRC don't care. Note however that for the rest of that tax year, the most you can insert into an ISA would now be £5k:                 +---------ISA-------+ ----- £5k --------->               |                +-------------------+  even though the ISA is empty. This is because the limit is to the total inserted during the year. Yes, this is fine: You can save up to £20,000 in one type of account or split the   allowance across some or all of the other types. You can only pay £4,000 into your Lifetime ISA in a tax year ... Example   You could save £11,000 in a cash ISA, £2,000 in a stocks and shares ISA, £3,000 in an innovative finance ISA and £4,000 in a   Lifetime ISA in one tax year. https://www.gov.uk/individual-savings-accounts/how-isas-work You might want to consider whether it is wise to be fully invested in shares. If you're going to have to dip into them for things like holidays and a car, you're taking a risk that you might have to sell when the market is low. As a basic rate taxpayer, you have a £1 000 personal savings allowance. You don't need to chase the tax break with a cash ISA, which often have poor rates. However, you should consider keeping some of your savings in cash, for example in a current account that pays decent interest on the balance.
