Twelve of the questions we get asked most often. If yours is not here, just call us — we are straightforward people.
Still have a question we have not answered?
Most standard boiler installations are completed in a single day — typically 4 to 8 hours depending on the complexity of your system. A straight swap of a like-for-like combi boiler is usually on the faster end. Installing a new system from scratch, converting from a system boiler to a combi, or running new pipework may take up to two days. We will always give you a realistic timeframe before we start.
Yes. Every engineer at Eco Heat Surge is Gas Safe registered — the mandatory legal certification required to work on gas appliances in the UK. You can verify our registration on the official Gas Safe Register website at gassaferegister.co.uk. We carry our ID cards on every job and are happy to show them before we start work.
Warranties vary by manufacturer and model. Ideal boilers come with up to 12 years warranty when installed by an approved installer — which we are. Alpha Heating offers up to 10 years on their flagship range. We will confirm the exact warranty available on your chosen boiler during the quote process. All warranties require annual servicing to remain valid.
Yes. We cover the whole of South Yorkshire including Sheffield, Rotherham, Doncaster, and Wakefield, as well as all Barnsley postcodes from S70 to S75. If you are unsure whether we cover your specific area, call us on 01226 885022 and we will confirm within the hour.
Yes. Annual boiler servicing is one of our core services. We carry out full safety inspections, flue gas analysis, controls checks, and issue a service certificate on the day. We also offer a reminder service so you never miss your annual service and inadvertently void your manufacturer warranty.
Once a year, without exception. Annual servicing keeps your boiler running efficiently and safely, catches small problems before they become expensive breakdowns, and is required by all major manufacturers to keep your warranty valid. Skipping a service voids your warranty and can also affect your home insurance. We recommend booking before October — before the winter demand surge.
Most boilers last between 10 and 15 years with regular servicing. If your boiler is within this age range and showing problems, replacement is usually more cost-effective than repeated repairs. Key signs you need a new boiler: unusual noises such as banging or kettling, only the heating or hot water working but not both, visible leaks or drips, the pilot light going out frequently, or your energy bills rising noticeably. If in doubt, call us for a free assessment.
The clearest sign is that 12 months have passed since your last service. Beyond that, watch for: unusual noises the boiler does not normally make, only heating or hot water working but not both, any visible leaks or drips around the unit, the pilot light going out regularly, or anything that simply seems out of the ordinary. If you are unsure, it is always safer to book a check than to wait.
A like-for-like combi-to-combi swap in Barnsley starts at £1,600. A heat-only-to-combi conversion (cylinder removed, pipework reworked) starts at £2,400. Larger system or regular boilers for higher hot water demand start at £2,995. Pricing depends on the boiler brand, model, and complexity — we provide a free, fixed-price quote before any work starts. No hidden charges.
Yes. We offer finance options on boiler installations and central heating systems, with monthly payments starting from £29 per month depending on the system and term chosen. Finance is subject to status. We will explain all available options clearly during your quote so you can choose what works best for your budget. A new A-rated boiler will typically reduce your heating bills enough to offset a significant portion of the monthly cost.
We are Ideal and Alpha Heating approved installers, which means we can offer their extended manufacturer warranties of up to 12 years. During your free home survey, we will recommend the best brand and model for your property, hot water demand, and budget — not just the most expensive option.
Call us on 01226 885022 and we will do our best to assist. Boiler emergencies do not keep business hours and neither do we where possible. Response times and availability vary depending on demand — winter weekends are our busiest periods — but we will always be honest about when we can get to you rather than leave you waiting without a clear answer.
