Boiler Repair & Servicing in Clackmannanshire
Annual servicing, repairs and landlord gas safety certificates from £100
Boiler Repair & Maintenance
A boiler that has been serviced once a year is far cheaper to live with than one that has not. Most of the failures we see at peak winter (pumps, fans, diverter valves, expansion vessels) show themselves during a service months before they actually break. Catching them then is a cheap part-swap; catching them on Christmas morning is a different conversation entirely.
Our annual service runs between £100 and £160 depending on the boiler model and where it is fitted. The service covers full strip-down inspection, combustion analysis, gas pressure and flue checks, cleaning of key components and a written report you can keep with the manufacturer paperwork. We register the visit against the warranty so it stays valid.
Repair call-outs follow the same approach, diagnose first, agree a price in writing, then fix. Most jobs are sorted on the first visit because we carry the common spares: PCBs, fans, pumps, diverter valves, pressure sensors. If a part needs ordering we are clear about that on the day and book a return slot as quickly as possible.
Landlords get a streamlined Gas Safety Certificate (CP12) service: same-day issue, all the records you need for compliance, and recurring inspections diaried so you never miss a renewal. We work with several local letting agents already and can invoice direct if that is easier than chasing tenants.

Liam has been working in plumbing and heating for over ten years, starting on luxury new builds and moving into gas boiler installations, servicing and housing-association maintenance. Nexus is the local-focused business he set up to keep the same standards close to home in Clackmannanshire.
Yes. Every gas appliance we install, service or repair is signed off by a Gas Safe registered engineer. Liam carries his Gas Safe ID card on every visit and is happy to show it before any work begins.
We are open every day, 08:00 to 20:00. That covers most evening and weekend slots without needing an out-of-hours call. If you have an emergency outside those hours, ring and we will do our best to help or get you to the right number.
Yes. Quotes for boiler installs, heat pump installs and bathrooms are free and given in writing once we have seen the job, either in person or via photos and a quick video call. There is no obligation and no pressure to book.
Bank transfer is the easiest option for most jobs and we also accept card payments and cash. For larger installations we can stage payments across the project so you are not paying everything up front.
Yes. Most modern gas boilers are around 90% fuel efficient, compared with old non-condensing units that often run at 70% or less. Pair that with controls like room thermostats and TRVs and most homes see a clear drop in their gas bill across a winter.
A new boiler installation with Nexus typically falls between £1,600 and £3,000. The price depends on the brand, the size of the boiler, whether the existing pipework needs reworking, and whether you are upgrading to a system or combi setup. Every quote is fixed in writing before we start.
A like-for-like swap is usually a one-day job. A move to a different boiler type, a relocation or a full system flush can run to two or three days. We give you a clear timeline as part of the quote so you can plan around hot-water downtime.
We fit all the main brands including Worcester Bosch, Vaillant, Ideal, Baxi and Glowworm. We will recommend a model based on your property, your usage and the warranty cover that best suits the budget, not just the brand we get the biggest discount on.
Yes, removal and safe disposal of your old boiler is included in the price. We disconnect, drain down, lift it out and take it away on the same visit, so you do not need to arrange anything separately.
New boilers we install come with the manufacturer's warranty, which typically runs from 5 to 12 years depending on the brand and the model you choose. We register the warranty for you and walk you through how to keep it valid (mostly annual servicing).
Yes. Air source heat pumps run at lower flow temperatures than gas boilers, so the key to making them efficient in older properties is good design (radiator sizing, pipework checks and insulation). Done properly, an air source pump in an older home can be cheaper to run than a gas boiler.
Air source installations with Nexus typically run from £8,000 to £15,000. The final figure depends on the size of the property, the existing heating system, whether radiators or underfloor are involved, and any cylinder upgrades. Government grants like the Boiler Upgrade Scheme can offset a large portion of that.
Yes, modern units operate efficiently down to around -15°C, which covers a typical Scottish winter comfortably. Like any heating system they work best in a well-insulated home, but a properly sized pump will keep your house warm even on the coldest days.
Modern air source units are surprisingly quiet (most run at around 40 to 50 dB at one metre, similar to a fridge). We site them carefully so the noise is not directed at bedrooms or neighbouring properties, and we comply with the planning noise rules for heat pumps.
In most cases an air source pump qualifies as permitted development, so no planning permission is needed. There are conditions on size, position and proximity to boundaries, which we check for your property before quoting and make sure the install meets the rules.
Often yes, but not always. We survey each radiator against the new heat pump output and replace any that are undersized. Many homes need only a few changes, usually upstairs bedrooms or a couple of bigger living areas, to make the system run efficiently.
Yes. Annual servicing keeps your manufacturer warranty valid and helps the boiler run safely and efficiently. Most issues we catch on a service are small parts wearing out, much cheaper to swap than to wait for a winter breakdown.
A standard annual boiler service with Nexus is between £100 and £160 depending on the boiler model and accessibility. The service includes a full inspection, gas pressure and flue checks, cleaning of key parts and a written report.
Most repair jobs we sort on the first visit, common parts like PCBs, diverter valves, pumps and fans live in the van. If a manufacturer-specific part needs ordering we let you know straight away and book a return visit as quickly as possible.
A standard repair visit is between £100 and £400 depending on the diagnosis and parts required. We confirm the diagnosis and price before any chargeable work starts, so there is no surprise bill at the end of the day.
Yes. Liam works on every major boiler brand including Worcester Bosch, Vaillant, Baxi, Ideal, Glowworm, Main, Potterton and others. Years of housing-association maintenance work means we have seen most faults on most makes.
Yes. We carry out annual landlord gas safety inspections (CP12) across Clackmannanshire and the Forth Valley and issue the certificate on the same visit. We can put recurring inspections in the diary so you never miss a renewal.
Yes. A ground source pump pulls latent heat from the ground, which sits at 8 to 12 °C all year round, while an air source unit relies on the ambient air, which can swing from -10 to 20 °C. The ground source unit therefore runs at a more stable, more efficient temperature, especially mid-winter.
Ground source installations with Nexus typically run from £20,000 to £30,000. The biggest variable is the ground loop, horizontal trenches need land but are cheaper, vertical boreholes work in tight plots but cost more. The Boiler Upgrade Scheme grant can offset a meaningful portion.
Not necessarily. Horizontal slinky loops need a reasonable garden, roughly two and a half times the heated floor area. If space is tight, vertical boreholes drop straight down 80 to 150 metres and need very little surface area. We survey and quote both options.
From the day groundworks begin to commissioning, most projects run between two and four weeks. The ground loop work is the longest part, a few days for trenches, longer for a borehole. The pump and cylinder install usually takes three to five days once the loop is in place.
The pump unit itself is rated for around 20 to 25 years, similar to a high-quality boiler. The ground loop has an expected life of 50 to 100 years, once it is in, it is generally there for the rest of the building's life. That long life makes the upfront cost more economic over the system lifetime.
Yes, hybrid setups are common and can be a sensible stepping-stone. The heat pump handles the bulk of the heating most of the year and the gas boiler steps in on the very coldest days or for fast-recovery hot water. We design the controls so the cheaper heat source is always doing the heavy lifting.
Most bathrooms take around seven working days from strip-out to handover, depending on the complexity. Simple swaps can be done in five days, full re-routes with floor changes can stretch to ten. We give you a day-by-day plan as part of the quote so you know exactly what is happening when.
Either works. Many customers prefer to choose their own suite from a showroom and have us fit it. Others want us to handle everything end-to-end. We have trade accounts with local merchants and can pass the pricing on with a clear breakdown.
Yes. Liam runs the project end-to-end with a small, trusted local team (tiler, electrician [Part P registered] and plasterer included). You get one point of contact, one quote and one timeline rather than chasing multiple trades.
Yes. Re-positioning fittings is a common part of bigger refits, we re-route hot, cold and waste pipework, allow for the right falls on drains, and rebuild the floor where needed. We will flag any structural questions early so you know what is involved.
Yes. We tank, screed and tile wet rooms to current waterproofing standards, including formed falls and continuous tanking around tray-less shower areas. Walk-in showers with low-profile trays are also very common, both designs work well in older Scottish homes.
Workmanship is guaranteed for a year as standard (pipework, tiling, sealing, drainage). Manufacturer warranties on the suite, taps and showers are passed straight through to you in writing. If anything settles or moves in the first year we come back and put it right.
