FAQs

If you smell gas, do not turn any electrical switches on or off, do not use your phone inside the property, and do not light any flames. Leave the property immediately, leave the door open, and call the National Gas Emergency Service on 0800 111 999. This line is free and available 24 hours a day. Once the situation has been made safe by the gas board, contact us and we can carry out any necessary repairs.

Carbon monoxide is odourless and colourless, which makes it extremely dangerous. Symptoms of exposure include headaches, dizziness, nausea and confusion. If you suspect a carbon monoxide leak, get everyone out of the property immediately and call 999. Do not re-enter until the property has been declared safe. A carbon monoxide alarm is a simple and inexpensive way to protect your household - we strongly recommend fitting one near your boiler.

Yes. An annual boiler service is recommended for all gas, oil and LPG boilers. Regular servicing keeps your boiler running safely and efficiently, helps prevent unexpected breakdowns, and is required by most manufacturers to keep your warranty valid. Find out more on our boiler servicing page.

Yes. Most boiler manufacturers require evidence of annual servicing to honour a warranty claim. If your boiler develops a fault and you cannot demonstrate it has been serviced regularly, your claim may be refused. Stonehenge Plumbing and Heating provide a full service record after every visit.

A boiler service includes a thorough inspection of all key components. For gas and LPG boilers our engineers check gas pressure and flow, combustion efficiency, electrical connections, fans, seals, electrodes, safety devices, the condensate trap, and all water and gas pipework. Oil boiler services also include replacing oil nozzles and cleaning the heat exchanger. A written report is provided after every service. See our boiler services page for a full breakdown.

Low boiler pressure is usually caused by a leak on the boiler or heating system, or by bleeding your radiators, which releases air from the system. A common cause is a flat expansion vessel, which can activate the pressure relief valve. If your pressure keeps dropping, it is worth having an engineer investigate as it may indicate an underlying fault. Contact us and we can carry out a diagnosis.

We operate a 24-hour emergency callout service and aim to respond to boiler breakdowns as quickly as possible. Our vans are stocked with the most commonly needed parts, meaning in many cases we can diagnose and fix the fault on the same visit. Call us on 01722 212050 for emergency boiler repairs in Salisbury and the surrounding area.

Some of the most common faults we repair include faulty zone valves, failing central heating pumps, pressure loss, ignition problems, thermostat faults, and blocked condensate pipes. In many cases the issue is in the heating system rather than the boiler itself. Find out more about our boiler and heating repair service.

When a boiler or heating system is repaired, the system usually needs to be drained and then refilled with water. As a consequence, this can occasionally cause leaks to appear on other parts of the system such as joints and pipework. This is not the engineer's fault - it is an unavoidable side effect of the repair process. If this happens, call us back and we will locate the leak and recommend the best course of action.

This depends on the age of your boiler, the nature of the fault, and the cost of the repair relative to a replacement. Repair tends to make sense when your boiler is under 10 years old and the fault is straightforward. Replacement starts to make more sense when your boiler is 12 years or older, has broken down more than once recently, or when the repair cost is significant. Our engineers will always provide quotes for both options and give you honest advice with no pressure either way. Read more on our boiler replacement page.

Common signs include frequent breakdowns, rising energy bills, uneven heating around the home, the boiler taking longer to reach temperature, unusual noises, or a boiler that is more than 12-15 years old. If you are unsure, our engineers can assess your boiler and give you an honest recommendation. Find out more on our boiler replacement and installation page.
