What's a CP12 and do I need one as a landlord?

A CP12 (Landlord Gas Safety Record) confirms every gas appliance in a rented property has passed an annual safety check by a Gas Safe registered engineer. It's a legal requirement before letting and at each renewal, a copy has to go to tenants, and it needs to be renewed every 12 months without a gap.

What's actually checked during an annual boiler service?

A service includes a visual and functional check of the boiler's casing and controls, flue gas analysis to confirm safe and efficient combustion, checking the flame picture and pressure, inspecting seals and condensate, and testing safety devices. It's a safety check as much as a performance one, and it's what keeps most manufacturer warranties valid.

What if a part for my existing boiler isn't available anymore?

Manufacturers stop stocking parts for discontinued models after a number of years, and once that happens a repair simply isn't possible even if the fault itself is minor. We'll confirm parts availability with the manufacturer before quoting a repair, and if it's a dead end we'll explain your replacement options honestly.

What paperwork do I get once the job's finished?

You'll get a Benchmark commissioning checklist for the boiler, a building notice or Building Control completion certificate for notifiable work, manufacturer warranty registration confirmation, and a Gas Safe (or OFTEC) record of the work. Keep these together — they're what a future buyer's solicitor or a warranty claim will ask for.

What's the difference between a boiler service and general maintenance?

A service is the annual manufacturer-required safety and efficiency check that keeps the warranty valid. Maintenance covers everything else — bleeding radiators, checking system pressure, sorting minor faults, and periodic flushing or filter checks — that keeps the system running well between those annual services rather than replacing them.

Local Maintenance & Repair for Shepton Mallet

Before quoting for maintenance & repair, we start with what's actually there: the existing pipework, the flue route, the water pressure and the age of what you've already got. Guesswork on a heating system leads to call-backs and wasted money, so a proper look at the property comes first. We're Gas Safe registered and OFTEC registered, based at 24 Bristol Road, Radstock BA3 3EE, and we size and specify jobs on what we find on site, not on assumptions. Typical era of build is georgian, which affects existing pipework and system cleanliness. Our van runs the A37 to reach you, 7 miles out from the Radstock workshop. In Shepton Mallet itself (BA4, Somerset) that usually means georgian terraces and modern estates, roughly 7 miles from the workshop.

What the buildings in Shepton Mallet change about the job

Georgian townhouses bring their own set of practical issues: tall, narrow flue runs, thick solid walls that make routing new pipework more involved, and in many cases conservation constraints on anything visible from the street. High ceilings and large room volumes also change how a heating system needs to be sized compared with a modern equivalent-sized property. We survey these properties with that in mind rather than applying a standard modern-house specification to a building that doesn't behave like one. Most of what we open up here is georgian terraces and modern estates, which dictates flue routes and pipe sizing. Our van runs the A37 to reach you, 7 miles out from the Radstock workshop. Shepton Mallet is roughly 7 miles from our Radstock base via the A37. Typical property stock here: Georgian terraces and modern estates. Mains gas covers most of Shepton Mallet, so the usual choice is between a modern combi or a system boiler with a cylinder — we'll size it correctly for the home, not just swap like-for-like. Repair calls in Shepton Mallet usually get a same-week visit, with most common faults fixed on the first attempt.

Where to go from here

If you're not in a rush, arranging maintenance & repair outside the depths of winter usually means more flexibility on scheduling and a calmer job overall. If you are in a rush because something's already failed, tell us that when you call so we can prioritise accordingly within our normal working hours. Photos of the existing setup speed up pricing for town properties like these. Our van runs the A37 to reach you, 7 miles out from the Radstock workshop. Planning constraints are usually light here, so external work is checked first.

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 Shepton Mallet, 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.

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.

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.

Access and parking constraints before we start work

Shepton Mallet's narrow terraced frontages affect how a job is planned before any pipework is touched. A boiler, cylinder or radiators have to be carried in, and on some streets that means checking parking permit zones or loading restrictions in advance rather than on the day; on farm tracks it means confirming a van can actually reach the building in wet weather, since a track that's fine in summer can be impassable after heavy rain. Old equipment being removed — an oil tank, an old cylinder, a cast iron boiler — needs the same access route in reverse, and weight matters as much as width. We ask about access and parking at the quoting stage specifically so it doesn't become a delay on the installation day.

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.

Signs a boiler repair is no longer the right call

A boiler that's failing repeatedly, needing a different part replaced every service, or over roughly ten to fifteen years old is approaching the point where continued repair costs more over time than replacement, particularly once a heat exchanger — the most expensive single part — starts to show signs of failure through leaks or reduced output. Efficiency is the other half of the calculation: an older non-condensing boiler running at 70-80% efficiency against a modern condensing combi at over 90% means a meaningful chunk of every unit of fuel burned in the old boiler is simply lost up the flue. We give a straight answer on repair versus replace based on the fault found and the boiler's age and condition, rather than defaulting to whichever is more profitable to us on the day.
