WHEN TO CALL
When You May Need Heating & Hot Water Support
Radiators staying cold
One radiator, a group of radiators or the whole system fails to warm as expected.
No hot water
The cylinder is not heating, hot water runs out unusually quickly or the controls do not respond.
Uneven heating
Rooms heat at different rates, or the system struggles to circulate heat where it is needed.
Pumps or pipework making noise
Persistent noise during operation can need checks of circulation, controls, supports & system condition.
Leaking valves or cylinder connections
Visible drips, damp insulation or water around heating & hot water components needs investigation.
WHAT WE DO
Understand the System. Restore Performance.
Radiators & circulation
We assess radiator output, valves, pumps & the distribution pipework to understand why heat is not reaching the right areas. The findings determine whether adjustment, component repair or further investigation is appropriate.
Hot water cylinders & controls
We investigate hot water performance, accessible cylinder connections, controls & associated components. We explain the cause indicated by the checks & the proposed work before replacing parts.
Heating pressure loss
We look for visible leaks & consider the condition of components before treating a pressure drop as proof of a hidden pipe leak. Where concealed pipework needs investigation, we explain the specialist leak detection survey.
System maintenance & repairs
We support heating & hot water maintenance, component replacement & pipework repairs. The repair is checked under suitable operating conditions, with remaining concerns explained at handover.
CLEAR PRICING
Know What Your Attendance Covers
What is included
The agreed hourly attendance covers the initial assessment, authorised heating or hot water labour & appropriate checks of the completed work. We discuss the findings, the repair options & any required components before proceeding.
After the first hour, hourly labour is charged in 15 minute increments. The applicable rate & scope are agreed before work begins.
What is not included
Materials, replacement components, new equipment & reinstatement are separate. Power flushing may be required before a leak detection investigation if system condition prevents effective testing; it is quoted separately before work begins. Boiler gas work requires an appropriately registered engineer.
HOW IT WORKS
From First Checks to Handover
Understand the symptoms
We review pressure changes, heating patterns, hot water performance & when the issue occurs.
Inspect the system
We assess accessible pipework, radiators, cylinders, pumps & relevant controls.
Separate the causes
Checks distinguish circulation, component & control problems from a suspected hidden leak.
Agree the repair
We explain the work, relevant rate & parts or separate investigation required.
Complete & check
We carry out the agreed work & test operation under appropriate conditions.
Review next steps
We explain the result, any monitoring needed & relevant maintenance advice.
KNOWLEDGE & EQUIPMENT
Experience Guides the Investigation
Our knowledge of sealed heating systems, hot water storage & circulation helps us interpret the readings. The tools used depend on the agreed scope; specialist tracer gas analysis is used within an appropriate leak detection investigation.
Equipment We Use
- Pressure testing
- Temperature checks
- Thermal imaging
- Moisture mapping
- Borescope inspection
- Tracer gas analysis
SPECIALIST SUPPORT
Heating System Leak Investigations
A specialist leak detection survey focuses on locating the leak, with a professional report of the findings. Some leaks are found in a few hours; others require several days of testing.

Heating & Hot Water FAQs
How much is heating & hot water work?
The hourly rate is £100 + VAT from 8am to 5pm, £125 + VAT from 5pm to 9pm & £150 + VAT out of hours. After the first hour, labour is charged in 15 minute increments.
Does pressure loss always mean a hidden leak?
No. Accessible leaks or problems with heating components can also cause pressure loss. We assess the evidence before recommending an investigation of concealed pipework.
What if the heating loses pressure over a week?
Is power flushing included?
Power flushing is a separately quoted service. If it is needed before a leak detection investigation, we explain the reason & agree its cost first.
Do you work on hot water cylinders?
We investigate hot water performance, cylinder connections, controls & associated components, with the scope & engineer requirements confirmed before attendance.
How long will the investigation take?
Some faults are identified within a few hours. Hidden or complex faults can require further investigation or a return visit. We agree the approach & charging arrangement before proceeding.
