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.

Can you look over a quote I've already had from another company?

Yes, this comes up often. Send or bring in the other written quote and we'll go through the spec — boiler size, controls, cylinder if included, and what's actually listed for parts and labour — and tell you plainly whether it looks right for the property, oversized, or missing something we'd expect to see.

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.

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.

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.

Is there mains gas across Coleford?

Most of Coleford is on mains gas, though pockets towards Kilmersdon and Leigh upon Mendip can be off-grid. We'll confirm what's at the property as part of the survey.

Coleford's Local Boiler Servicing Specialist

Boiler Servicing sits alongside the wider servicing cycle a heating system goes through over its life: commissioning, annual checks, and eventually replacement once repairs stop making sense. Thinking about where you are in that cycle helps decide whether now is the right time to act. We're Gas Safe registered and OFTEC registered, based at 24 Bristol Road, Radstock BA3 3EE, and happy to talk through where your system currently sits before recommending anything. Our van runs the A367 to reach you, 4 miles out from the Radstock workshop. Typical era of build is mixed-cottage, which affects existing pipework and system cleanliness. In Coleford itself (BA3, Somerset) that usually means former mining cottages and estates, roughly 4 miles from the workshop.

Reading the property before pricing the work

Being close to our Radstock base means straightforward logistics for a job here — quick access for the survey, easy return visits if anything needs revisiting, and no long travel factored into how the work is scheduled. That doesn't change the standard of the work itself, but it does tend to make arranging visits and follow-ups a bit more flexible than for properties further out toward the edge of the area we cover. Mains gas covers much of the area, with off-grid pockets, which changes the appliance shortlist. Water here is very hard limestone water, so scale protection is specified accordingly. Coleford is roughly 4 miles from our Radstock base via the A367. Typical property stock here: former mining cottages and estates. Coleford sits in the Somerset BA3 postcode and is part of our weekly run, so local response is quick. Annual services in Coleford include a full safety check, efficiency report and warranty stamp where applicable.

The parts of the job people rarely mention

Radiator sizing after lowering the flow temperature

Running a boiler at a lower flow temperature — typically 55°C or below rather than the old default of 70-80°C — improves condensing efficiency measurably, but it also reduces the heat output of every radiator in the house, because a radiator's output falls roughly with the square of the temperature difference to the room. Radiators sized correctly for a 75°C flow can end up unable to heat the room properly at 55°C unless they're upsized or supplemented. We check each radiator against the lower design flow temperature before recommending it, and where a room falls short we look at whether a larger single panel, a double panel, or an additional radiator on that circuit closes the gap, rather than pushing the flow temperature back up and giving away the efficiency gain.

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 Coleford 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.

Pumped-oil versus gravity feed: does it matter?

Older oil systems sometimes still rely on gravity feed, where the tank sits higher than the burner and oil flows down to it under its own weight; a pumped system uses the burner's internal pump to draw oil up from a tank at any level, including below the boiler. Gravity feed limits where a tank can be sited and is more prone to airlocks if the line runs dry, while a pumped system is more flexible on tank position but needs the pipe run and lift height kept within the burner pump's rated capacity — usually no more than a few metres of lift and a set maximum run length. When we replace an oil boiler we check which type the existing tank and pipework support before assuming a straight swap, because a tank sited for gravity feed may need repositioning or a different pump to suit a modern burner.

Coleford's A367 corridor and what it means for scheduling

Properties along or near the A367 corridor around Coleford are generally straightforward to reach without the access constraints of side lanes or unclassified roads further off the main network, which helps with scheduling deliveries of boilers, cylinders or oil tanks to a fixed slot. It doesn't change the technical requirements of the job itself, but predictable access does mean less contingency time needs building into a visit, and it makes coordinating a delivery with an installation date more reliable than on a property with a difficult final approach. We still confirm any specific parking or loading restriction on the immediate street before a job, since a fast main road doesn't guarantee easy stopping right outside the property.

How a condensing boiler recovers extra heat

A condensing boiler passes flue gases through a secondary heat exchanger before they leave the flue, extracting additional heat by condensing water vapour in the exhaust back into liquid, which is expelled as the mildly acidic condensate water down the drain. This is why every condensing boiler needs a condensate drainage route as part of its installation, unlike older non-condensing boilers, which simply vented hot dry gas straight out. The efficiency benefit only fully materialises when the boiler is actually condensing regularly, which needs a return water temperature low enough — generally below 55°C — for water vapour to condense in the first place. A condensing boiler run permanently at a high flow temperature can spend much of its time not actually condensing, which is one of the main reasons flow temperature settings matter as much as the boiler model chosen.

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.
