Most people arrive here because something has gone wrong, the boiler is losing pressure every few days, the hot water has turned lukewarm, or an engineer has quoted a repair that costs more than the unit is worth. The honest answer is that a boiler past twelve years old, needing a part that costs several hundred pounds, is usually worth replacing rather than nursing through another Scottish winter. We have been replacing boilers here for over 30 years, so that judgement comes from watching how these houses age rather than from a price list.
We replace boilers across every G74 and G75 street, and because East Kilbride was built fast and to pattern, we have almost certainly worked on your exact layout before. That is why we can price the overwhelming majority of homes here from a few questions online rather than sending someone to sit in your living room for an hour.
A straight swap, combi out, combi in, same position, takes a few hours. You will have heating and hot water back the same day. Where the job is bigger, like removing a back boiler or moving the unit to a different wall, it runs to a full day and we say so up front rather than discovering it halfway through.
People often ask what makes the best boiler replacement company in East Kilbride. It is not the lowest headline number. A cheap boiler in East Kilbride usually turns out to be a quote with the flush, the filter, the certificate or the removal stripped out of it, and the difference reappears on the invoice. The honest boiler price for East Kilbride is the one that still covers all of that.
How much does a new boiler cost in East Kilbride?
The figure people quote online is rarely the figure they pay, because it excludes the flush, the certification or the removal of the old unit. Ours does not. A straight combi swap in a one or two-bedroom flat or terrace starts at £1,299 fully installed. A three or four-bedroom semi, the most common house type in East Kilbride, typically lands between £1,495 and £1,835 depending on the brand and warranty length you choose.
A full conversion, where a back boiler and fire come out and the cylinder and loft tanks go with them, starts at £1,695 and is priced individually from your photos and details. It costs more because it is genuinely a bigger job: a full day, more materials, a chimney to cap and often a gas supply to upsize.
What moves the price is rarely the brand. It is whether the flue can stay where it is, whether the gas run is adequate, and whether the system is clean enough to accept a modern condensing boiler without a full power flush.
If a quote looks unusually cheap, check whether it includes the flush, the filter, the certificate and the removal. That is almost always where the difference is hiding.
Replace or repair? An honest test.
We repair boilers too, so we have no particular interest in selling you a new one when a part would do. The rough test we use on the phone is this:
- Under 8 years old and a common part has failed: repair it. A diverter valve or a fan on a modern unit is a straightforward fix and the boiler has years left.
- Over 12 years old and the repair is more than a third of a replacement: replace it. You are paying a large sum toward a unit that is already inefficient and out of warranty.
- It has failed twice in one heating season: replace it. Two callouts in a winter usually means the heat exchanger or the system water is the underlying problem, not the part that happened to break.
- You are on a back boiler: replace it. Parts availability is now genuinely poor, efficiency is roughly half a modern condensing unit, and you get a cupboard back.
- It works fine but your bills are climbing: get it serviced first. Correct balancing and a working thermostat often recovers more than people expect, and we will tell you if that is the cheaper route.
Broken boiler replacement in East Kilbride
Emergency boiler replacement in East Kilbride is work we keep capacity for every week, because a boiler that has failed completely will not wait for a convenient appointment.
No heating in January with a young family or an elderly relative in the house is not something that waits. If your boiler has failed completely, send the form through and mark it urgent. If the boiler you choose is in stock at the merchant we can often install the same day, and a new boiler is usually a 24 hour turnaround.
If we can safely get you running again with a temporary fix while the new unit is ordered, we will do that first and it costs you nothing extra. Nobody should sit in a cold house because a part is a day away.
Which boiler suits an East Kilbride home?
Sizing is driven by radiators and bathrooms, not bedrooms, and oversizing is the single most common mistake we are called out to correct. A boiler that is too powerful short-cycles, wears its components faster and costs more to run, not less.
A typical three-bedroom semi in Westwood or Calderwood with one bathroom is well served by a 24 to 28kW combi. Add a second bathroom or an en-suite and 30 to 32kW starts to make sense. Beyond that you are usually better with a system boiler and an unvented cylinder than an ever-larger combi. Getting that call right, over many years in business and more than 6000 happy East Kilbride customers, is most of the job.
- Worcester Bosch: the default recommendation. Greenstar 4000 and 8000, up to a 12-year warranty, and parts available locally same-day.
- Ideal Heating: Logic Max and Vogue Max, also up to 12 years, and generally a little keener on price for the same warranty.
- Navien: strong hot water performance from the NCB700 ON series, worth considering if the shower pressure is the thing that annoys you.
- Vokera: Easi-Heat Plus, up to 10 years, and the sensible choice where budget is the deciding factor.

Our old boiler packed in on the Sunday. I sent photos through the form that night and had a fixed price back before lunch on the Monday. New one installed on the Thursday. Never needed anybody in the house just to get a price, which suited me fine with the wee ones about.
KM Karen M. Calderwood, G74 Boiler replacement · March 2026 -
Got three prices. This was not the cheapest but it was the only one that was clear about what was included, and it was the only one that did not need somebody sitting in my living room first. Boiler installed, system flushed, filter on.
DW Derek W. Whitehills, G75 Boiler replacement · February 2026 -
Whole thing was done online. I filled the form in, sent a picture of the old boiler and the meter, and the quote came back the same day. No pressure afterwards either, which I appreciated.
ES Elaine S. Stewartfield, G74 Boiler replacement · March 2026 -
Back boiler out, combi in, and we got the airing cupboard back. They told me up front what the flue would need and the price never moved from the quote. Tidy job and they took all the old stuff away.
SD Stuart D. Westwood, G75 Combi conversion · February 2026 -
Older sandstone place and I expected a fight about it. They asked the right questions on the form, priced it properly, and the installed price was the price I paid.
SL Susan L. Village, G74 Boiler replacement · November 2025 -
Annual service, in and out in under an hour, and I got the paperwork emailed the same afternoon for the warranty. Straightforward and no trying to sell me anything I did not need.

Straight Answers
Boiler replacement pricing depends on the specific model chosen and the labour required for the installation. A direct combi boiler swap in the same location is the most cost-effective option, whereas removing a back boiler or completing a full system conversion requires additional work — such as removing old cylinders, tanks and modifying pipework — which increases the overall costs. Every project is accurately assessed prior to quoting, ensuring the final written price is guaranteed.
- Combi swaps from £1,299: The most economical option when replacing an existing combi boiler in the same location, and usually only a few hours' work.
- Conversions from £1,695: Removing old tanks, cylinders and redundant pipework takes more labour and materials, and usually a full day.
- Full central heating from £2,399: Boiler, pipework, radiators and controls designed together, usually about two days.
- Guaranteed Quotes: The written price provided following our assessment is the final amount you pay, with no hidden surprises.
A like-for-like combi boiler swap normally takes a few hours, and you have heating and hot water back the same day. If the flue needs to be relocated, the gas supply upgraded to 22mm or an old hot water cylinder and loft tanks removed, allow a full day. We confirm the exact timeframe during the quoting stage rather than surprising you on the morning of installation.
- Same-Day Swaps: Standard, direct combi replacements finished in a few hours.
- Full-Day Installations: Complex jobs involving flue relocations, gas pipe upgrades or conventional system conversions.
- Clear Timelines: Fully transparent scheduling confirmed upfront before any work begins.
A straight combi swap starts at £1,299 and a three or four-bedroom semi is usually £1,495 to £1,835 fully installed. If you are comparing against a cheap quote elsewhere, check whether it includes the chemical flush, the Building Standards certificate and removal of the old unit. Ours does.
For a straight swap we can normally install within 24 to 48 hours of you accepting the quote. If the boiler you choose is in stock at the merchant we can often get it the same day; if it is not, a new boiler is usually a 24 hour turnaround. If you have no heating at all we prioritise the job.
Yes, as long as the details you give us are accurate. The figure changes if you ask us to add work once we are there — extra radiators, a smart control, relocating the unit — and anything like that is priced and agreed with you before we start. Extra charges may also apply where the information given at quotation stage turns out not to match what we find, as set out in our terms and conditions.
As a rule of thumb: under eight years old with a common part failure is worth repairing; over twelve years old with a repair costing more than a third of a replacement is not. Two failures in one heating season usually points at the heat exchanger or the system water rather than the part that broke.
Yes, and it is one of the most common jobs we do in East Kilbride. We remove the boiler and fire, cap and make safe the chimney, take away the cylinder and loft tanks, upsize the gas supply where the run needs it, and install your new combi. From £1,695, usually in a day, and you get the airing cupboard back.
The size you need is not necessarily the size you currently have. Most homes in East Kilbride run on boilers that are significantly oversized, causing them to cycle on and off frequently and burn more gas than necessary.
- Oversized Units: Many existing systems are too large for the property, leading to inefficient fuel consumption and constant cycling.
- Accurate Sizing: We calculate your exact heating requirements based on the number of radiators and shower output rather than a simple like-for-like swap.
- Optimised Efficiency: Ensures your new boiler operates at peak efficiency, keeping your heating bills as low as possible to save you money.
Up to 12 years on Worcester Bosch Greenstar, Ideal Logic Max and Vogue Max, and Navien NCB700 ON models, and up to 10 years on Vokera Easi-Heat Plus. Registering the warranty with the manufacturer is the customer’s responsibility, and most manufacturers allow around 30 days from installation to do it.
The boiler is paid for in full before installation. You then pay the gas engineer their fee directly, once the work is finished. Most of our customers pay by credit or debit card, which is the quickest way, and we also accept secure bank transfer. We do not offer finance.
The old boiler and all packaging leave with us at no extra cost, and are recycled through a licensed waste carrier. Tanks are different. A tank in the loft is usually drained and left where it is, because taking it out can cause a lot of damage and disruption to hallways and staircases. Where a tank or cylinder sits in a hall cupboard and can be removed easily, we take it away free of charge.
A chemical flush is included as standard on every replacement. A magnetic system filter is an optional extra at £95, since many homes already have one. On older East Kilbride systems with heavy sludge, common in gravity-fed properties in the Murray and Calderwood, we will tell you if a full power flush is the sensible route.
Yes. Every quote we give is done this way. A few questions are usually enough to price a home in East Kilbride, because most of the housing here follows a small number of familiar layouts. If we need to see something in particular, we will ask you for a photo instead of sending a salesperson out.
Yes. Flats bring their own considerations, flue termination, access for the old unit and sometimes factor permission for external work, and we will flag any of that in your quote rather than turning up and finding it.
Get in touch with us first and we will point you in the right direction. Every new boiler comes with a manufacturer warranty, and the manufacturer is contacted directly to arrange a repair engineer. We do not handle warranty claims on your behalf or carry out free repairs, but we are local to East Kilbride and happy to help you work out who to speak to.
