ReliaHeat investigates heating and hot-water faults for customers across Edinburgh and the Lothians.
If your system has stopped working, is losing pressure or is displaying an error code, a Gas Safe registered engineer can assess the problem and explain the available repair options.
When contacting us, please include the appliance manufacturer, model and any fault code shown on the display.
Heating faults can have several possible causes, so the system should be inspected before a repair is recommended.
Contact ReliaHeat if you are experiencing:
Where possible, tell us the make, model and fault code when requesting an appointment.
1. Tell Us About the Fault
Let us know what has happened, when the problem started and whether an error code is displayed.
2. Engineer Assessment
An engineer will inspect the appliance, heating system and relevant controls to identify the likely cause.
3. Explanation and Recommendation
We will explain the identified problem and the proposed work before proceeding wherever practical.
4. Parts and Further Work
Where a replacement part is required, we will explain the next steps and any additional cost before arranging further work.
5. Testing
Once the work is complete, the system and relevant controls will be tested to check that they are operating correctly.
Do not use the website contact form to report a gas or carbon-monoxide emergency.
Open doors and windows, avoid flames and electrical switches, turn off the gas at the meter where it is safe to do so, and call the National Gas Emergency Service immediately on 0800 111 999.
The emergency line is free and operates 24 hours a day. It is separate from ReliaHeat’s repair service.
Limited out-of-hours appointments may occasionally be available, subject to engineer availability and additional charges. Contact us to confirm availability before relying on an out-of-hours visit.
A repair may be the most practical option when the fault is isolated and suitable parts remain available. Replacement may be worth considering when:
We will explain the fault and available options. Where replacement is being considered, you can also view our boiler-installation service.
Servicing is planned maintenance for a working appliance. A repair addresses an existing fault or loss of heating or hot water.
Where the system is operating normally but is due its annual service, contact us to arrange the appropriate appointment.
We inspect the appliance and relevant controls before recommending repair work.
The identified problem and proposed solution will be explained before additional work is undertaken wherever practical.
Where replacement parts or a return visit are required, we explain the next steps and applicable costs.
Work on gas appliances is completed by appropriately qualified Gas Safe registered engineers.
Based in Bonnyrigg, ReliaHeat serves customers across Edinburgh, Midlothian and East Lothian. Contact us with your postcode to confirm appointment availability.
Contact us with the manufacturer, model and fault code. We will confirm whether we can work on the appliance and whether suitable parts are likely to be available.
Some faults can be repaired during the initial appointment. Others may require replacement parts or further investigation. The engineer will explain the next steps after diagnosing the fault.
Pressure loss may result from a leak, pressure-relief-valve fault, expansion-vessel problem or another system issue. Continually repressurising it without identifying the cause is not a permanent solution.
Switch the appliance off where it is safe to do so and contact a qualified engineer. Do not remove the casing or attempt gas-related repairs yourself.
This will depend on the boiler’s warranty status, the fault and the manufacturer’s terms. Check your warranty documents before authorising chargeable repair work.
Out-of-hours boiler repair appointments may be available, subject to engineer availability. Contact us to confirm the current service and applicable charges.
Tell us what has happened, your postcode, the appliance make and model, and any fault code displayed. We will confirm the next available appointment.
