Let me think...
£38 - head gasket set with bolts (
; PM me if you want seller)
£17 - water pump (
£44 - belt and tensioner (Dayco)
£89 - head pressure testing and skim
£16 - alternator and PAS belts
£11 - thermostat
...so that's around £220; around £45 less if no skim required.
Tools I didn't hold were a trustworthy torque wrench, an angular gauge, and a 1/2" > 3/8" socket converter - £29, £9 and £4 respectively.
Misc stuff? Hylomar Universal Blue, emery paper, degreaser, Jubilee clips for hoses, RadFlush, copious quantities of rags and kitchen roll, paraffin... another £20.
Liquids and associated bits: two engine's worth of
filters (£7 each), coolant (£10).
Cost to me was north of £320 before replacing both the hose that was broken and the hose I broke.
