Here's what to actually look for, on both repairs and installations, to know a job's been done properly. Get a Free Quote07523 738285 Gas Safe registered no. 576059: fixed written prices before work begins It's easy to assume a heating job has gone well simply because the boiler is working when the engineer leaves. But there's a difference between a boiler that switches on and a job that's been done to a proper standard, and that difference often only becomes obvious months later, when something that was rushed or skipped starts to cause problems. Whether you're having a boiler repaired or a new one installed, here's what quality actually looks like in practice, and what to check for before, during and after the work. ## Paperwork that actually matters Proper heating work always comes with paperwork, and it's not just a formality. For any new boiler installation, this should include a Gas Safety Certificate, confirming the work has been checked and signed off correctly. This certificate is provided FREE with every new boiler installation from Harrison E Jones Heating. You should also receive a fixed written price agreed before work starts, so there's a clear record of what was agreed and what it covered. If a job finishes without any paperwork at all, that's worth questioning, since it leaves you with nothing to fall back on if a problem arises later. ## Cleanliness and care on site How an engineer treats your home during the work is a genuine indicator of how much care they're taking overall. Dust sheets down, tools kept tidy, and mess cleared away as the job progresses all suggest a methodical approach, and that same care usually extends to the technical side of the job too. Making good after the work, meaning basic patching of any disturbance to walls or flooring caused by pipework changes, should be part of a proper job, even if full redecoration isn't included. A rushed, messy job is rarely a well-executed one underneath. ## Commissioning done properly Commissioning is the process of setting a new boiler up correctly once it's physically installed, and it's one of the most important steps for both performance and longevity. This includes checking gas pressure at the meter and at the boiler, confirming safe and correct flue operation, checking the condensate drain is working, and setting the boiler's parameters correctly for the specific system it's connected to. A boiler that's fitted correctly but not properly commissioned can run inefficiently or develop faults early. Proper commissioning takes time and shouldn't be rushed just to finish the job quickly. ## Balancing the system System balancing, adjusting the flow of water through each radiator so heat is distributed evenly across the property, is often skipped in lower-quality installations because it takes time and doesn't affect whether the boiler switches on. But without it, some rooms can end up too hot while others struggle to reach temperature. A properly balanced system means the whole house heats evenly and the boiler isn't working harder than it needs to in some areas to compensate for others. It's a detail that's easy to miss but makes a real difference to day-to-day comfort and running efficiency. ## Warranty registration Most new boilers come with a manufacturer's warranty, but that warranty typically depends on the boiler being registered correctly after installation, and sometimes on specific installation requirements being met. A quality installer will register the warranty on your behalf and make sure you understand what it covers and what's needed to keep it valid, such as an annual service. Skipping or mishandling this step can leave you with a boiler that looks covered but isn't, which only becomes apparent if you ever need to make a claim. ## Common boiler faults and what they usually mean A boiler losing pressure repeatedly often points to a small leak somewhere in the system, or a faulty pressure relief valve, rather than something that will fix itself. No heating but hot water still working, or the other way round, often points to a diverter valve or airlock rather than a full boiler failure. Banging or gurgling noises can be a sign of air in the system or, on older boilers, a build-up of sludge restricting flow. A proper repair starts with correctly diagnosing which of these is actually happening, rather than replacing parts on guesswork. That diagnosis is where a quality repair visit differs most from a quick fix that might get the boiler running again without addressing what caused the fault. ## Tank-to-combi conversions Converting from an older tank-fed system to a combi boiler is one of the bigger jobs a heating engineer takes on, and it's worth understanding what's involved. It typically means removing the cold water storage tank and the hot water cylinder, capping off the pipework that fed them, running new pipework to the new boiler location, and confirming the mains supply has enough pressure and flow to support a combi. Done properly, a conversion frees up loft and airing cupboard space and gives instant hot water at mains pressure. Done poorly, it can leave a property with disappointing flow rates or unused pipework left in place. It's a job worth getting a proper survey for rather than a quick estimate over the phone. ## What to check before you book a repair or installation Before booking, check the engineer is Gas Safe registered and ask for their registration number, confirm you'll get a fixed written price before work starts, and ask what the visit will include and roughly how long it will take. For installations, ask whether a survey is needed first and what it covers. It's also worth asking what happens if something unexpected is found once work is underway, such as further faults during a repair, or additional pipework needed during an installation. A straightforward answer here is usually a good sign. ## What this looks like with Harrison E Jones Heating New boilers are fully fitted from £1,299, with a fixed written price agreed before any work starts.

What does commissioning a boiler involve?Commissioning includes checking gas pressure, confirming correct flue operation, checking the condensate drain, and setting the boiler's parameters correctly for your system. Why does system balancing matter?Balancing adjusts water flow through each radiator so heat spreads evenly across the property, rather than some rooms overheating while others stay cold. Does Harrison E Jones Heating register boiler warranties?Yes, warranty registration is part of a proper installation, alongside the FREE Gas Safety Certificate provided with every new boiler. How can I tell if a boiler fault is serious?Repeated pressure loss, no heating or no hot water, banging noises, or any smell of gas all warrant a proper visit. A gas smell should be treated as urgent, leave the property and call the National Gas Emergency Service on 0800 111 999. Is a tank-to-combi conversion worth doing?It depends on your property and hot water needs. It frees up space and gives instant hot water at mains pressure, but it's a bigger job than a like-for-like swap and needs a proper survey to check mains flow first. What should I check before booking a repair or installation?Confirm the engineer is Gas Safe registered, ask for a fixed written price before work starts, and check what happens if further issues are found once the job is underway.
