How easy is it to replace a toilet — can I do it myself?

Honest answer: a straight like-for-like swap is one of the more achievable DIY plumbing jobs, but only in the right circumstances. If the new toilet is a standard close-coupled pan going in exactly the same position, a competent DIYer with a spare half-day can do it: isolate the water at the isolation valve, flush and drain the cistern, disconnect the supply, unbolt the old pan, fit a new flexible pan connector to the soil pipe, level and fix the new pan, reconnect and check carefully for leaks.

The usual snags are not the new toilet but the old one — seized fixing bolts, a brittle old soil connection that cracks when disturbed, or corroded pipework that starts weeping once touched. Have a plumber's number ready before you start, not after.

Call a plumber from the outset if anything is moving: repositioning the toilet means altering soil and waste runs, and new soil or waste connections can fall under Building Regulations (routine like-for-like replacements don't). Wall-hung toilets and concealed cisterns buried in stud walls are also professional territory — mistakes hide behind tiles. And anything involving electrics (macerator toilets, for example) or unvented hot water systems is a different category of work altogether, with its own regulations.

If it is beyond a simple swap, compare vetted local plumbers or get free quotes — a straightforward toilet fit is a quick job for a professional.
