It is also what most manufacturers require to keep a boiler warranty valid, and warranties on new boilers typically run from 5 to 12 years. We service combination, system and conventional boilers of all brands, whoever installed them, as long as they run on natural gas. We do not work on LPG. Every service is carried out by a Gas Safe registered engineer, registration number 17648. Because we are heating engineers rather than a boiler-only call-out service, we look at the boiler as part of the whole system: the pressure, the expansion vessel, the controls and the condition of the water running through your radiators. If something elsewhere is shortening the boiler's life, you will hear about it. ### Who it is for Dunmow homeowners and landlords with a natural gas boiler that is due its annual service, or has gone more than a year without one. ### What it costs From £90 + VAT, parts extra. No call-out fee and no hourly rate. Any extra work is quoted as a fixed price first. ### Why it matters Safety, running costs and warranty cover all depend on the boiler being checked and maintained every year. Left as it is ## What skipping a boiler service really costs A missed service rarely causes a problem the next day. The cost builds up quietly and arrives all at once, usually when the heating is needed most. ### A void warranty Most manufacturer warranties require an annual service with a record of it. Miss one and a repair that should have been covered can land on you. ### Breakdowns in the coldest weeks Worn seals, blocked condensate pipes and failing components are easy to spot during a service and much harder to deal with when the house is already cold. ### Higher gas bills A boiler that is not burning cleanly or is short-cycling uses more gas to deliver the same heat. ### Safety left unchecked Combustion, flue integrity and safety devices need checking by a Gas Safe registered engineer. Without a service, nobody is looking. ### Common mistakes we are called out to - Waiting until the boiler stops working before calling anyone - Assuming a boiler that still lights is working safely - Losing the service record the warranty depends on - Ignoring a pressure gauge that keeps dropping - Booking the service in mid-winter instead of before the heating season ## Our process, from first call to guarantee 01 ### Book a visit Call or send an enquiry and we will arrange a time to come to your Dunmow home. 02 ### Visual and safety checks We check the boiler, flue, condensate and surrounding installation, and confirm the appliance is operating safely. 03 ### Service to manufacturer guidance Components are inspected and cleaned as the manufacturer specifies, and gas rate, pressures and combustion are checked and set. 04 ### System checks System pressure, the expansion vessel and the controls are checked, along with the general condition of the heating system. 05 ### Findings explained We tell you in plain English what we found. If anything needs attention, you get a fixed price before any extra work is carried out. 06 ### Service recorded The service is recorded so you have the evidence your warranty needs. What you get ## The practical difference on your job ### Clear starting price Servicing from £90 + VAT, parts extra. No call-out fee and no hourly rate added on top. ### Gas Safe registered Gas Safe registration 17648, ACS qualified, with £2 million public liability insurance. ### All boiler brands We service any make of boiler running on natural gas, whoever installed it. ### 37 years of experience Neil has worked on heating systems for 37 years, with his son Sam working alongside him. ### Whole-system view We are heating engineers, so we look beyond the boiler at the pressure, controls and radiators it depends on. ### No surprise bills Any repair or part is priced and agreed with you before we do it. In detail ## Looking after your heating in Dunmow A service is the best single thing you can do for a boiler, but it works best alongside a few simple habits and the right advice. ### When to book Once a year, ideally in late summer or early autumn before the heating goes under full load. Any developing fault is then found while the weather is still mild and there is time to put it right. If you cannot remember when the boiler was last serviced, or you have just moved into a house in Dunmow and have no records, it is worth booking one now rather than waiting for the anniversary. ### Signs your boiler needs attention sooner A pressure gauge that keeps dropping, radiators that are cold at the top, hot water that runs lukewarm, new noises from the boiler, or a pilot or flame that looks different from usual are all reasons not to wait for the annual service. These are often small faults that are quick to put right when caught early. Left alone, they can strain the pump, heat exchanger or other expensive components. ### Servicing a newer boiler If your boiler is still within its manufacturer warranty, the annual service is what keeps that cover in place. Warranties on new boilers typically run from 5 to 12 years depending on the boiler. If we installed it, our own 10-year guarantee on labour and pipework sits alongside the manufacturer warranty. ### When repair stops making sense Sometimes a service shows that a boiler is near the end of its working life: parts are hard to source, faults keep returning, or an expensive repair is likely. When that happens, we will tell you honestly and leave the decision with you. If you do decide to replace it, we fit all boiler brands on natural gas with a fixed price quote, and can survey for it at the same visit.
