To find the cost of one pencil, we need to divide the total cost of the 8 pencils by the number of pencils. 

Here's the calculation:

\[
\text{Cost of one pencil} = \frac{£3.81}{8}
\]

\[
= £0.47625
\]

Rounding this to the nearest penny:

\[
\text{Cost of one pencil} = £0.48
\]

So, the cost of one pencil is **£0.48**.
