Boiler Repair & Servicing in Gillingham

Why Choose Advance Medway for Boiler Repair in Gillingham

Gillingham is one of our busiest areas for boiler repairs, and that frequency works in your favour. Our engineers know the housing types, the common heating configurations, and the typical faults that affect boilers across the ME7 and ME8 postcodes. Whether you live in an ex-MOD property near Brompton Barracks, a 1970s semi in Twydall, or a newer build in Hempstead Valley, we have almost certainly worked on your type of property before.

All our engineers are Gas Safe registered and carry the parts most commonly needed for boiler repairs across all major brands. We provide an honest diagnosis, a fixed-price quote before any work starts, and we complete the repair on the same visit wherever possible. If a part needs to be ordered, we will arrange a return visit at no extra charge. We do not charge a call-out fee during normal working hours, and our pricing is transparent from start to finish.

For Gillingham residents facing an emergency — a boiler that has stopped working entirely, a suspected gas leak, or a carbon monoxide alarm — we offer priority emergency callouts. Call 01634 979 595 and let us know the situation.

Common Boiler Problems We Fix

Across Gillingham, the boiler faults we see most often include:

• Loss of pressure — frequently caused by small leaks in the system, a faulty pressure relief valve, or a failed expansion vessel
• No hot water despite heating working — typically a diverter valve fault, common in combi boilers over 8 years old
• Boiler cutting out or showing error codes — ignition failures, fan faults, or overheating due to blocked heat exchangers
• Banging, whistling, or rumbling noises — often caused by sludge buildup or limescale in the heat exchanger, a condition known as kettling
• Leaking from the boiler casing or pipework — worn seals, cracked heat exchangers, or corrosion in older systems
• Radiators not heating evenly — air locks, circulation problems, or sludge restricting flow through the system

We repair Worcester Bosch, Vaillant, Baxi, Ideal, Potterton, Glow Worm, and all other major manufacturers.

Boiler Servicing for Gillingham Homes

With such a large and varied housing stock, Gillingham homes benefit enormously from regular boiler servicing. The post-war properties that make up much of the ME7 and ME8 area were often built with heating systems that have been upgraded over the years — sometimes professionally, sometimes not. An annual service by a qualified Gas Safe engineer ensures that your boiler is operating safely and efficiently, regardless of its age or the history of the installation.

During a service, we carry out a thorough inspection of every accessible boiler component. This includes checking the burner and heat exchanger for wear or damage, performing a flue gas analysis to measure combustion efficiency, testing gas pressure and flow rates, inspecting seals and gaskets for deterioration, and confirming that all safety devices — including the overheat thermostat and pressure relief valve — are functioning correctly. We also check the condensate pipe, verify system pressure, and bleed any radiators that need attention.

Gillingham has a large number of rental properties, particularly in the ME7 postcode area closer to the town centre. If you are a landlord, annual gas safety checks are a legal requirement under the Gas Safety (Installation and Use) Regulations. Our servicing visits for Gillingham rental properties include all the checks needed for your CP12 gas safety record. We can set up annual reminders so you never miss a renewal.
