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.

How much longer does a full conversion take compared to a straight boiler swap?

A straight like-for-like swap in the same location is typically a single working day. Converting boiler type (for example back boiler to combi, or oil to LPG), relocating the boiler, or adding a new cylinder usually needs one to two extra days for additional pipework, flue routing, and electrical work, which we'll scope out at survey.

What support do I get after the install is finished?

Once commissioning's complete we talk you through the controls, leave the paperwork, and register the manufacturer warranty on your behalf. If anything doesn't feel right in the first few weeks — a fault code, an odd noise, a control setting you're unsure of — call us during office hours and we'll talk it through or come back out.

How often should a boiler actually be serviced?

Once a year is the standard recommendation from every manufacturer, and most warranty terms make it a condition rather than a suggestion — miss a year and a claim can be refused even if the fault is unrelated. Landlords have a separate legal duty to have gas appliances checked annually regardless of warranty terms.

Who actually carries out the work?

A Gas Safe and, where relevant, OFTEC registered engineer from our own small team carries out the job — we don't sub the install out to a third party after quoting. You deal with the same people from survey through to commissioning and any aftercare calls.

Do I need to do anything to activate my boiler's warranty?

As a Worcester Bosch Accredited Installer we register qualifying Worcester installs on your behalf, which is what unlocks the extended guarantee (up to 10 years* on qualifying installs) rather than the standard shorter term. For other brands we still register the installation; keep the confirmation with your other paperwork in case you need it.

Landlord Gas Safety Certificate (CP12)

Landlord Gas Safety Certificate (CP12), Combe Hay

Landlord Gas Safety Certificate (CP12) sometimes happens as an emergency, when a system has already failed, and sometimes as a planned replacement while the current one is still limping along. Both are valid reasons to get in touch, and the survey and quote process is the same either way. We're Gas Safe registered and OFTEC registered, contactable on 07516 118198 during our normal hours, Monday to Friday, 8:30am to 5pm. Terrain is valley floor, which matters for condensate runs and tank siting. Typical era of build is mixed-cottage, which affects existing pipework and system cleanliness. In Combe Hay itself (BA2, Somerset) that usually means stone farmhouses and cottages, roughly 6 miles from the workshop.

Flue and pipework detail from a landlord gas safety certificate (cp12) job in Somerset, landlord gas safety certificate (cp12) in Combe Hay (BA2) — 6 miles from our Radstock base

Stone cottages and farmhouses around here were mostly built long before central heating existed, so pipework and boiler locations have usually been retrofitted at some point, sometimes more than once. Thick stone walls, uneven floor levels and low ceilings can all affect where a boiler or cylinder can practically go, and older stonework doesn't always take fixings the way modern block or brick does. We work around those constraints on site rather than assuming a straightforward install. Most of what we open up here is stone farmhouses and cottages, which dictates flue routes and pipe sizing. Mains gas covers much of the area, with off-grid pockets, which changes the appliance shortlist. Combe Hay (BA2) has a healthy private-rental sector, particularly across stone farmhouses and cottages. We service a number of letting-agent portfolios across the area and keep the certification cycle running so renewals never slip.

Technical notes for this job type

Chasing pipework into lime plaster and stone walls

Solid stone or cob walls finished in lime plaster, common in the older parts of Combe Hay, behave very differently to modern plasterboard when a pipe run needs chasing in. Lime plaster is softer and more porous than gypsum, so cutting a neat, consistent chase without blowing the surface needs a slower hand and finer disc than a stud-wall job, and any repair has to be made good in a lime-based skim rather than modern filler, which can trap moisture behind it and cause the patch to fail. On solid stone we sometimes surface-mount pipework in painted conduit instead of chasing, particularly where the wall is a significant structural thickness and chasing would weaken it. Knowing which approach a wall needs before starting avoids expensive plaster damage.

LPG as an alternative to oil off the gas grid

Properties around Combe Hay 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.

Village lane access and van positioning for larger jobs

Village lanes around Combe Hay are often single-track or tight two-way roads without dedicated off-street loading space, which affects how a larger job like a full system installation or an oil tank replacement is planned — the van needs somewhere to park close enough for repeated trips carrying equipment without blocking the lane for through traffic or farm vehicles. On a job involving a full radiator or pipework replacement, materials sometimes need staging over more than one visit rather than delivered all at once if there's nowhere secure to leave them on-site between visits. We check lane width and passing places when scheduling larger jobs in village locations, and plan van access and parking as part of the job rather than as an afterthought on the day.

Heating where a home sits alongside commercial premises

Properties around Combe Hay that combine living accommodation with an attached shop, workshop or other commercial space often need heating designed as genuinely separate zones with independent controls, since a shop's occupied hours and heating demand rarely match the flat or house above it. Where the two shared a single ageing system, splitting them onto separate zone valves — or, on a larger scale, separate boilers — stops one side subsidising or interfering with the other's heating schedule. Commercial space also sometimes falls under different servicing and safety-record obligations than the residential side, depending on how it's used, so it's worth establishing which parts of the building fall under which regime before assuming a single annual service covers everything.

Condensate soakaways where there's no convenient drain

Properties without a nearby internal waste connection or external gully for the boiler's condensate — common on rural plots around Combe Hay where the nearest drain run is a long way from the boiler's location — sometimes need a dedicated condensate soakaway instead. This is a small pit filled with granular material that the condensate, which is mildly acidic, can disperse into gradually rather than running to a drain at all. Sizing and siting it correctly matters: it needs to be far enough from foundations and sited where the local ground can actually absorb the modest but steady volume a boiler produces, particularly over a long heating season. Where ground conditions make a soakaway unreliable, running a longer insulated pipe to a proper drainage connection is usually the safer long-term choice even though it's more work to install.

Working across Somerset: what being local changes

Being based at 24 Bristol Road, Radstock, 6 miles from Combe Hay via the B3110, means a callout doesn't involve a long cross-county drive, and it also means familiarity with the recurring patterns in the local building stock — stone farmhouses and cottages — rather than encountering that construction type for the first time on-site. Local knowledge doesn't replace a proper site survey, but it does mean fewer surprises: knowing in advance that a particular postcode area typically has hard water, older single-pipe circuits, or restricted parking means the quote reflects the likely reality of the job before the first visit. We're Gas Safe and OFTEC registered and work across Somerset on that basis, not by claiming coverage we don't actually deliver on.

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.

Booking work in Combe Hay

Correct sizing matters more than most people realise for landlord gas safety certificate (cp12): an undersized system struggles to keep up, and an oversized one costs more to run and buy than it needs to. We size against the property's actual heat loss and hot water demand, not a rule of thumb. Send the appliance make, model and any fault code and you get a straight answer, not a sales script. Water here is very hard limestone water, so scale protection is specified accordingly. Mains gas covers much of the area, with off-grid pockets, which changes the appliance shortlist.
