Time Well Spent™
We charge by time spent, not by task.
Before starting work, we’ll explain what we expect to do and how long it should take.
If the work takes less time, you pay less.
If more time is needed, we’ll agree it with you before continuing.How this works in practice →
All rates are inclusive of VAT. Minimum booking is one hour; time thereafter is billed in 15 minute increments.
Parts and materials, if required, are charged separately.
Expected durations
For common work, we use typical time ranges based on experience. These are not fixed prices, but typical time ranges to help you understand what’s involved.If work changes
Sometimes a job reveals additional issues once work has started. If this happens, we’ll explain what we’ve found and agree any additional time with you before continuing.Servicing and faults
Routine boiler servicing is expected to take up to one hour. If faults are identified during that time, we’ll explain the options before carrying out further work.Efficiency
We don’t charge more for working efficiently. If work takes less time than expected, you only pay for the time used. We’re open about time on site and happy to talk through how it’s being spent.Parts and materials
Parts and materials, if required, are charged separately and will always be discussed before fitting.Back to main page →
At Rochester Plumbers, we believe customers deserve clarity about time and costs.Our engineers work with precision, and if a routine job takes longer than it should because of us, you won’t pay a penny extra. It’s part of our commitment to Better Service, Better Value – Every Time.There are, however, a few situations where we may need to pause, reassess, or agree a revised plan with you. These aren’t loopholes; they’re simply the moments where safety, access or the condition of a system naturally change what’s possible. We keep these to a minimum - and we explain them with complete transparency.1. When the system is older or hasn’t been maintainedOur timings assume a reasonably modern, well-maintained boiler or heating system.
If it is over 15 years old, lacks a service history, or shows signs of long-term wear, we may need additional time to work safely and responsibly.2. When previous work doesn’t meet current standardsIf we discover earlier work that isn’t aligned with today’s safety or industry standards - for example unconventional alterations or legacy installation practices - we’ll pause the clock and clearly outline your options before continuing.3. When access isn’t safe or straightforwardWe need clear, safe access to the boiler, valves and working area.
We may need to reassess the timing if, for example:- The boiler is enclosed or boxed in- Bath panels are permanently sealed- The loft lacks safe flooring or lighting- Essential valves or components cannot be reachedIf improved access is required, we’ll explain exactly what’s needed.4. When something unexpected comes to lightOccasionally, a simple job reveals something that could not have been reasonably foreseen - such as a seized stop tap, a hidden leak, or an electrical concern. When this happens, we pause the job, keep you fully informed, and agree the best next step together.5. When the system is non-standard or specialistSome homes have specialist systems that naturally require more time, such as:- Thermal stores or heat banks- Gravity systems- HIUs (district heating)- Older or unusual boiler modelsThese may involve additional steps to ensure safe and correct diagnosis.6. When delays are beyond our controlOur promise covers delays caused by us - not delays caused by access issues, third-party attendance, or repeated interruptions during the visit.How We Approach ItIf any of these situations arise, your engineer will:- Pause the clock- Explain what we’ve found, clearly and calmly- Outline your options, including any revised timing- Only continue with your approvalThis ensures you always remain in control - with no hidden surprises.In SummaryThe Time Well Spent™ Promise ensures that if delays are on us, you will never pay for them. When something outside our control affects the nature of the job, we handle it with the clarity, care and professionalism that sit at the heart of our brand.Better Service, Better Value – Every Time.
