This is an expected consequence of trading fees. When you place a bid order, an amount of the counter asset (GBP in your case) is reserved from your available balance. The exact amount reserved is computed as the quantity of the order (here, 0.1000 BCH), multiplied by the limit price of the order (here, £1800/BCH). To guarantee that your account balance can never go negative, trade fees are charged against the reserved amount, meaning that your order can purchase at a maximum a slightly smaller quantity than you ordered. You might wonder why the trade fee isn't reserved up front in addition to the order total. The reason is that the exact fee rate charged depends on your trailing 30-day trade volume at the time of the trade. The fee rate you would be charged at trade time is unknown at the time you place your order. Charging the trade fees against the reserved amount allows you to trade your entire counter asset balance without concern for variable fee rates.
