About this service
Toilet repairs in Kingston upon Thames: running, leaking or not flushing
A continuously running toilet can waste 200-400 litres a day — more than a family of four uses. It's almost always the flush valve seal, the fill valve, or the flush mechanism itself, and it's usually a quick, affordable fix once diagnosed.
We also handle full toilet replacements, including concealed cistern and wall-hung systems.
Toilet won't flush
A handle or button that does nothing is a broken link, a split siphon diaphragm or a failed flush valve. A weak flush is usually a low water level in the cistern or scale in the rim. Both are repaired without replacing the toilet.
Toilet keeps running
Water trickling into the pan means the flush valve seal is not closing. A cistern that never stops filling is the fill valve. Either one wastes water every hour until it is fixed.
Leaking at the base or cistern
Water on the floor comes from the pan connector, the cistern bolts or the supply connection. If the toilet is blocked rather than leaking, see blocked drains.
New toilet installation
Close-coupled, back-to-wall and wall-hung toilets fitted, including concealed cisterns and frames, with the old toilet removed.

Frequently asked
Toilet repair FAQs
How do I know if my toilet is leaking internally?
Dry the back of the pan above the waterline and stick a small piece of toilet paper to it. Check back in ten minutes — if it's wet, water's trickling through from the cistern.
Why does my toilet keep running?
The flush valve seal has perished or scaled up, or the fill valve is not shutting off. Both parts are inexpensive and normally replaced in one visit.
Can you repair a concealed cistern?
Yes. Most concealed cisterns are serviced through the flush plate opening, so no tiles need to come off.
Should I repair or replace my toilet?
Repair if the china is sound and parts are available. Replace if the pan or cistern is cracked, or if it is an old high-volume model you want to swap for a water-saving dual flush.
