Toilet Repairs & Toilet Replacements
Many toilet faults can be repaired quickly and economically — a tired fill valve, a slipped flush mechanism or a worn cistern seal is often a same-visit fix. Older units, or toilets that have been patched up repeatedly, often benefit from a clean replacement. FFT Plumbing & Heating covers both — toilet repairs and full toilet replacements across Brentwood, Chelmsford and the wider Essex area.
- Most toilet repairs completed on the first visit
- Honest repair-vs-replacement advice (no upselling)
- Close coupled, back-to-wall, wall hung & concealed cistern fits
- Common fill valves, flush valves & seals carried on the van
Common toilet faults we repair
If your toilet is doing any of these, it's almost always a same-visit fix. Toilet repair in Brentwood and across Essex is one of our most common call-outs.
Leaking toilets
Water pooling at the base, behind the pan, or seeping from the cistern.
Constantly running toilets
Cistern that never stops refilling — usually a worn fill or flush valve.
Flush problems
Weak flush, no flush, or having to hold the handle down.
Broken fill valves
Slow-filling cisterns, noisy refills or overflows running into the pan.
Concealed cistern repairs
Geberit, Roca and Wirquin units serviced through the flush plate.
Noisy or hammering cistern
Banging, whistling or vibrating pipes when the cistern refills.
Repair or replacement? Honest advice first
We don't sell new toilets unless they're the right answer. Here's how we look at it on every job.
Repair makes sense when…
- The pan and cistern are in good condition
- It's a worn fill valve, flush valve or seal
- The WC matches the bathroom you want to keep
- Spares are available for the model
Replacement makes sense when…
- The unit is 15+ years old or has been repaired repeatedly
- The pan or cistern is cracked, crazed or badly stained
- You're modernising the bathroom or cloakroom
- You want to switch to back-to-wall, wall-hung or concealed cistern

Why customers choose FFT for toilet work
Repair first, replace only when it makes sense
Most toilet faults are a £-something part, not a £-hundreds new WC. We say so.
Concealed cistern specialists
Wall-hung and concealed installs need the frame, waste and tiling to align perfectly. That's where we live.
Left clean and sealed
Old WC removed and disposed of, new unit silicone-sealed and pressure-tested before we leave.

Before & after — WC modernisation, Chelmsford
A dated back-to-wall WC and basin replaced with a concealed cistern toilet and fluted vanity unit.
Challenge: The customer wanted to modernise their downstairs cloakroom by replacing a dated back-to-wall toilet and small wall-mounted basin with a contemporary vanity unit and a new concealed cistern WC. Although on paper it looked like a straightforward swap, the existing pipework boxing didn’t match the footprint of the new furniture, so the new units couldn’t simply be dropped into place. The cistern feed, waste connection and basin services all needed to line up precisely with the new vanity and WC unit while keeping the plumbing accessible for any future maintenance.
Solution: After stripping out the old sanitaryware, I carefully modified the existing pipework boxing so the new vanity unit and concealed cistern furniture would slot perfectly into position, while keeping service access where it mattered. New water supplies and waste pipework were then connected, fully aligned to the new units, and pressure-tested before commissioning. To finish, I sealed all the exposed edges of the vanity and WC unit with a neat silicone bead so the furniture reads as built-in rather than bolted on.
Result: The cloakroom now feels like a completely different room — a sleek green fluted vanity with a brushed brass tap and matching concealed cistern WC replace the dated suite, giving the customer a modern, space-saving finish with hidden storage and a properly built-in look.
