I'm looking for a reliable handyman to replace my toilet flush cistern. The current unit leaks occasionally and I want a modern, compatible replacement installed with proper seals and fittings. Ideally, you can bring or source a compatible cistern and any required hardware. Please confirm the exact model compatibility for a standard UK close-coupled toilet and provide an estimate for parts and labour. I’ll need the work done with minimal disruption, and I’d prefer a quick turnaround on a weekday. Access to the bathroom is straightforward, and I can accommodate any follow-up adjustments if needed.
