A heating system is one of the biggest investments you'll make in your home, and getting it right the first time matters. ZM Plumbers installs, upgrades, and replaces heating systems across Luton for homeowners, landlords, and local businesses, from a single new boiler to a full central heating system fitted from scratch. Our Gas Safe registered engineers don't just fit whatever's cheapest. We size the system to your property, your radiator count, and how you actually use your heating so you're not paying to heat a house that's already warm or shivering through a system that can't keep up. Every installation comes with clear, upfront pricing before any work begins and a 12-month workmanship guarantee once it's done. No surprise costs, no vague quotes, no pressure to upgrade to something you don't need. Call today for a free, no-obligation quote from your local heating engineer in Luton.
Installing a heating system properly takes more than a spanner and a set of instructions. It takes knowing how Luton’s housing stock actually behaves—the pre-war terraces around Bury Park with their older pipework, the post-war semis in Stopsley, and the newer flats near the town center. Each one needs a slightly different approach, and that’s the kind of knowledge you only build by working in an area for years.
We install heating systems the way we’d want one installed in our own homes: correctly sized, properly balanced, cleanly fitted, and fully explained before we start.
A new heating system should last you 12 to 15 years. It’s worth having it fitted by someone who’ll still be around if you ever need them.
Most people only think about their boiler when it stops working. But an older system quietly costs you money every single month, and an inefficient boiler running at 70% efficiency means roughly 30p in every pound you spend on gas is going straight out of the flue.
A modern condensing boiler runs at over 90% efficiency. On a typical Luton three-bedroom home, upgrading from an old non-condensing system can meaningfully cut your annual heating bill, and you get a system that actually heats the house evenly instead of leaving the back bedroom cold.

Not every home needs the same system, and the right choice depends on more than just budget:
suit smaller homes and flats with one bathroom. They heat water on demand, so there’s no cylinder taking up space in an airing cupboard but they can struggle if two showers run at once.
are usually the sensible choice for older Luton properties that already have a cylinder and a cold water tank in the loft, where a full conversion would mean tearing out a lot of existing pipework unnecessarily.
works beautifully with modern well-insulated extensions and new builds, running at lower temperatures and giving a much more even heat than radiators.

Every heating system installation we carry out follows the same process, so you know exactly what you’re getting:
An oversized boiler cycles on and off, wastes gas and wears out faster. We calculate the right output for your property instead of fitting whatever’s in the van.
The price we agreed on before we started is the price you pay. No mid-job “we found something” surprises.
Dust sheets down, old system removed, pipework run neatly, and your home left as we found it. Installation work shouldn’t leave a mess behind.
Every installation is Gas Safe certified, notified to Building Control, and backed by a 12-month workmanship guarantee alongside your manufacturer warranty.
Whether you're replacing a failing boiler before winter or upgrading a whole system, we'll survey the property and give you a clear fixed price with no obligation.
Our heating engineers install and upgrade heating systems across Luton and these nearby towns:
The cost depends on the type of boiler, the size of your property, and whether any pipework needs altering. A straightforward like-for-like combi swap costs considerably less than converting a conventional system to a combi. We provide a free survey and a fixed written quote before any work starts, so you’ll know the exact price upfront with no hidden extras.
A like-for-like boiler replacement is usually completed in a single day. A full system conversion or a brand-new central heating installation typically takes two to three days, depending on the property size and the number of radiators involved. We’ll confirm the expected timescale in your quote.
Both. We install complete heating systems including radiators, pipework, controls and thermostats — not just the boiler. If your existing radiators are in good condition, we’ll tell you honestly rather than replacing things that don’t need replacing.
In most cases, yes. Older non-condensing boilers typically run at around 70% efficiency, while a modern condensing boiler operates at over 90%. Combined with smart controls and properly balanced radiators, an upgrade usually leads to a noticeable reduction in gas consumption.
Yes. Every installation comes with a 12-month workmanship guarantee from us, in addition to the manufacturer’s warranty on the boiler itself, which we register on your behalf.6
