Is oil more expensive to run than mains gas?

Oil and gas prices both move with the wholesale market and neither is fixed, so a blanket answer isn't honest. What we can say is that a modern condensing oil boiler, correctly sized and commissioned, will run considerably more efficiently than an old non-condensing model — that efficiency gap usually matters more than the fuel choice itself.

What are your opening hours, and can you help out of hours?

Our published hours are Monday to Friday, 8:30am to 5pm, and that's when the phones are answered and jobs are booked. We're honest that we don't run a round-the-clock emergency line, so if you're planning ahead, call during those hours on 07516 118198 and we'll get you booked in.

Will the new boiler work properly with our existing radiators?

Not always without checking. Modern condensing boilers run most efficiently at lower flow temperatures, and radiators originally sized for an old, hotter-running boiler can end up struggling to heat a room adequately at those lower temperatures. We check radiator sizing against a heat loss calculation and flag any that are undersized for the room before installing.

What actually happens on install day?

The engineer isolates the gas or oil supply and water, removes the old boiler, fits and pressure-tests the new one, connects the flue and condensate, and commissions the system. For a straight swap this is usually one day; a conversion, relocation, or cylinder change can run into a second depending on the pipework involved.

Our houses are close together — are there rules about where a flue can go?

Yes, flue terminal positions are governed by set minimum distances from windows, doors, boundaries, and other flues, including a neighbour's opening windows. On terraced and closely built streets this sometimes limits where a boiler can go or means routing the flue differently to an old back boiler's position — we check this at survey, not after ordering.

Our Victorian terrace still has an old system boiler and separate cylinder — should we switch to a combi?

It depends on your hot water demand and pipework. A combi suits a property with one bathroom and modest simultaneous demand, while a system boiler with a cylinder copes better with two bathrooms running at once. Many Victorian terraces we work on keep the cylinder simply because the existing pipework and cupboard space make that the more practical upgrade.

Local conditions we plan around in BA3

Water here runs off carboniferous limestone and Jurassic oolite, which makes it very hard by national standards. Hard water accelerates scale build-up inside heat exchangers, cylinders and pipework, which shortens the working life of components that aren't protected against it. On jobs in this area we factor scale protection into the specification rather than treating it as an optional extra, because the difference between a protected and unprotected system shows up within a few years, not decades. It's a genuine local variable, not generic sales advice, and it applies whether the property is on mains gas or oil. homes alongside small commercial and agricultural premises make up most enquiries from this postcode. Welton is roughly 1 miles from our Radstock base via the A367. Typical property stock here: terraced cottages and 1970s estates. Welton sits in the Somerset BA3 postcode and is part of our weekly run, so local response is quick. Repair calls in Welton usually get a same-week visit, with most common faults fixed on the first attempt.

Technical notes for this job type

Electronic and physical scale reducers compared

In very hard limestone water areas like Welton, a scale reducer fitted on the boiler's cold feed protects the heat exchanger without the ongoing salt and drainage requirements of a full water softener. Physical scale reducers use a polyphosphate or template-assisted crystallisation cartridge that alters how calcium carbonate crystallises so it's less likely to adhere to hot surfaces; electronic and electromagnetic devices claim a similar effect without a cartridge to replace, though the evidence base for electronic types is weaker and more inconsistent than for physical media. Manufacturers including Worcester Bosch now specify a scale reducer or softener as a condition of extended guarantees in hard water areas, so the choice affects warranty validity as well as long-term performance, not just descale frequency.

Being minutes away in Welton

Welton sits close enough to our Radstock base, just 1 miles via the A367, that a diagnostic visit or a return trip for a part doesn't add the delay it would on a job further afield. That's practically useful on jobs where a fault only shows itself once a boiler's been running for a while, or where a part needs collecting after an initial diagnosis rather than being carried on the off-chance. It doesn't change how the job itself is done — the same Gas Safe and OFTEC standards and the same commissioning paperwork apply regardless of distance — but it does mean less waiting between visits on multi-stage jobs like a full system upgrade that needs a survey, a flush, and an installation visit in sequence.

Oil tank de-sludging: why it's not optional

Oil sitting in a tank for years accumulates water from condensation and fine sediment that settles at the bottom, and over time this forms a sludge layer that can be drawn into the fuel line, particularly when the tank is nearly empty and the outlet pulls from lower in the tank than usual. Sludge blocks fine oil filters and burner nozzles, which shows up as burner lockouts or a boiler that won't fire cleanly rather than as an obvious tank problem. De-sludging drains and cleans the tank base without necessarily removing the whole tank, and it's worth doing when a tank is inherited with a property, before switching to a new boiler, or if lockouts recur despite the filter and nozzle being replaced. It's a preventative job that's cheaper done on schedule than after a burner failure it caused.

Nozzle replacement and baffle cleaning on oil burners

An oil burner's nozzle atomises fuel into a fine spray for combustion, and it wears from constant fuel flow at pressure, gradually changing the spray pattern away from the burner manufacturer's specification even before it visibly fails. A worn nozzle burns less cleanly, producing more soot that coats the heat exchanger's baffles, and a sooted heat exchanger loses efficiency in the same way scale does on a gas boiler's plates. Standard practice on an annual oil service is to replace the nozzle as a matter of course, rather than wait for a fault, and to remove and clean the baffles so the heat exchanger surfaces are exposed to combustion heat properly again. Skipping nozzle replacement to save a service visit's minor parts cost is a false economy against the fuel wasted by a poorly atomising burner.

Common boiler fault codes and what usually causes them

Most modern boilers display a fault code on the control panel when they lock out, and while the exact code differs between manufacturers, the underlying causes cluster into a small number of categories: low system pressure (often from a small leak or after bleeding radiators), ignition failure (a worn electrode, gas supply issue, or blocked condensate causing a safety shutdown), or a failed sensor reporting an implausible temperature reading. A condensate blockage or freeze specifically tends to show a distinct code from a genuine ignition fault, which is why checking the external condensate pipe for ice before calling out an engineer in a cold snap can sometimes resolve the issue without a visit at all. We ask for the exact fault code and any recent history — a bled radiator, a cold snap, a recent service — before attending, since it often narrows down the likely cause before we arrive.

LPG as an alternative to oil off the gas grid

Properties around Welton that sit off the mains gas network aren't limited to oil — bulk LPG, stored in an above-ground tank on a concrete base with the same OFTEC-style clearance and access rules as oil, runs standard gas-rated boilers with only a change of injector and pressure setting rather than a different boiler entirely. It suits households that want a gas hob and gas-style modulation rather than an oil burner's on/off firing pattern. The tank still needs delivery access for a tanker, which on some rural driveways is the deciding factor over oil. We check the access route for the largest realistic delivery vehicle before recommending LPG over oil, because a tank that can't be filled easily causes more disruption than the fuel choice was meant to solve.

Why very hard limestone water shortens boiler life around Welton

The limestone geology under Somerset gives Welton very hard limestone water, which drops calcium carbonate out of solution as soon as it's heated. Inside a combi's plate heat exchanger the gaps between plates are only a millimetre or two wide, so scale narrows the waterways long before it's visible anywhere else in the system. The first symptom is usually a hot tap that runs warm rather than hot, or a boiler that fires more often for the same demand. Left unchecked, scale insulates the exchanger from the burner, forces flue gases hotter, and can crack the exchanger from thermal stress. A scale reducer fitted on the mains feed, sized to the property's flow rate, is cheaper to install once than to replace a heat exchanger twice.

Welton's place within the wider Somerset area we cover

Welton is one of several neighbourhoods we work in around the wider area, and while the postcode district and general water hardness and building stock trends are shared with the surrounding district, the specific street-level access, parking and property type still varies enough locally that we treat each visit on its own facts rather than applying a generic area answer. Nearby areas we also cover include Midsomer Norton, Radstock and Westfield, which is relevant mainly where a customer wants comparable jobs referenced or where a single visit can sensibly cover more than one nearby property in the same trip. The underlying trade standards — Gas Safe, OFTEC, correct commissioning — don't vary by neighbourhood, only the practical details of the job do.

Chimney liners for boilers using an existing flue

Where an older boiler used the property's original brick or stone chimney as its flue route, a replacement condensing boiler usually can't use the same masonry flue unlined, because the flue gases are cooler and wetter and will attack unprotected brickwork and mortar over time. A correctly specified stainless steel liner, sized to the boiler manufacturer's flue length and diameter tables, carries the flue gases safely and lets the existing chimney be reused rather than needing a new wall or roof penetration — often the only realistic option on a listed or solid-wall property in Welton where an external flue run isn't permitted. The liner has to be inspected and swept as part of ongoing servicing exactly as an open-fire flue would be, which is easy to overlook once it's hidden inside the chimney.
