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.

Is it worth upgrading the heating controls when we replace the boiler?

Where the existing controls are an old mechanical timer and single room thermostat, replacing them alongside the boiler with weather compensation or a modern programmable thermostat usually improves comfort and efficiency more than the boiler swap alone. It's not compulsory, but it's often the single best-value addition to a new install.

What does "commissioning" a boiler actually involve?

Commissioning is setting the boiler up correctly for the property rather than just switching it on: checking gas or oil pressure and flow rates, setting flow temperatures, testing safety devices, balancing the system, and completing the manufacturer's Benchmark checklist. Skipping this properly is one of the most common reasons warranty claims get refused later.

We run a holiday let — do the same gas safety rules apply as a standard rental?

Yes, holiday lets fall under the same landlord gas safety duty as any other let property — an annual CP12 from a Gas Safe registered engineer is required, and it's worth timing the visit for a gap between bookings rather than trying to fit it around guests, which we're happy to help plan around.

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.

Broughton Gifford's Local Landlord Gas Safety Certificates Specialist

Homeowners, landlords and smallholders tend to ask different questions about landlord gas safety certificates: homeowners want comfort and running costs sorted, landlords need compliant paperwork they can hand to tenants and agents, and rural owners often need to weigh oil against other fuels. We cover all three from 24 Bristol Road, Radstock BA3 3EE as a Gas Safe registered and OFTEC registered firm, so the advice is tailored to what you actually need the system to do. Terrain is level, which matters for condensate runs and tank siting.

Flue and pipework detail from a landlord gas safety certificates job in Wiltshire — Wiltshire

Reading the property before pricing the work

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. Mains gas covers much of the area, with off-grid pockets, which changes the appliance shortlist. Broughton Gifford is roughly 11 miles from our Radstock base via the unclassified. Typical property stock here: stone cottages. A meaningful share of properties around Broughton Gifford are off the gas grid, so oil boiler installs and tank swaps make up a fair part of what we do locally. Repair calls in Broughton Gifford usually get a same-week visit, with most common faults fixed on the first attempt.

Your next move in BA14

Correct sizing matters more than most people realise for landlord gas safety certificates: 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. Terrain is level, which matters for condensate runs and tank siting.

The parts of the job people rarely mention

Heating where a home sits alongside commercial premises

Properties around Broughton Gifford 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.

Village lane access and van positioning for larger jobs

Village lanes around Broughton Gifford 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.

LPG as an alternative to oil off the gas grid

Properties around Broughton Gifford 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.

Wood-burning stoves with a back boiler alongside a main boiler

Some older rural properties around Broughton Gifford run a wood-burning stove with a back boiler feeding heat into the same central heating circuit as an oil or gas boiler, usually through a thermal store or a cylinder with two coils. Getting this combination to work safely means the stove's back boiler circuit has its own means of dissipating heat if the pump fails or a valve closes while the stove is still burning — a stove can't simply be switched off the way a boiler can if its heat has nowhere to go, so a gravity-fed safety circuit or heat leak radiator is normally required. It's a more involved design than a single-boiler system and needs planning at the point either appliance is replaced, not treated as an afterthought once the new boiler is already fitted.

Single-pipe circuits in older stone cottages

A lot of the stone cottages and farmhouses around Broughton Gifford were plumbed decades ago on a single-pipe gravity circuit, where each radiator draws from and returns to the same loop rather than having its own flow and return. It works, but radiators furthest from the boiler receive water that's already cooled after giving up heat to the ones before it, so the far end of the house is always the coldest. Converting to a two-pipe layout means new pipe runs, which in a stone cottage often means chasing lime plaster or lifting flagstones — not a trivial job. Where a full rewire of the pipework isn't wanted, we sometimes improve balance instead by oversizing the radiators nearest the end of the run and fitting TRVs to hold back the ones nearest the boiler.

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.
