Plumbing and Heating FAQ — Devon

We aim to reach most Tavistock addresses within 2-4 hours depending on call volume. For rural properties on the edges of Dartmoor, allow up to 4 hours. Our engineers cover the full 20-mile radius from Tavistock including Okehampton, Launceston, and surrounding villages. When you contact us we will give an honest estimated arrival time upfront.

Yes. Okehampton and Launceston are both within our standard service area. Okehampton is approximately 15 miles north-east and Launceston is 14 miles north-west of Tavistock. We also cover all towns and villages in between including Lifton, Yelverton, Horrabridge, and the Tamar Valley. Request a quote online and we will confirm coverage for your exact postcode.

We do not charge a call-out fee. You only pay for the work carried out, at a fixed price agreed before we start. This applies whether you are in Tavistock, Okehampton, Launceston, or the surrounding Devon and Cornwall villages. Emergency work is priced the same as daytime work — no hidden surcharges.

Yes. For planned work such as boiler servicing, drain jetting, or bathroom quotes, same-day appointments are often available if you contact us before mid-morning. For urgent problems — blocked drains, leaks, or heating failures — we prioritise same-day attendance wherever possible across the Tavistock area.

Turn off your main water stop tap immediately — usually found under the kitchen sink or where the water main enters the property. If the burst pipe is near any electrics, turn off the power at the fuse box too. Drain your taps to relieve remaining pressure, then contact us for an emergency call-out. Do not leave a burst pipe unattended.

Your main stopcock is usually located under the kitchen sink, in an airing cupboard, or where the water main enters the building. Turn it clockwise to shut off the water supply. If you cannot find the internal stopcock, your external stop tap is typically in a small chamber in the pavement or driveway outside. South West Water can also shut off the external stop tap if needed.

Boiler repair in Devon typically ranges from £80 to £400 depending on the fault and parts required. Straightforward issues such as a faulty thermostat, pressure problem, or ignition fault are usually at the lower end. More complex repairs — replacing a heat exchanger or gas valve — cost more. We provide a fixed-price quote after diagnosing the fault, so you know the full cost before any work begins.

A standard annual boiler service takes approximately 60-90 minutes. Our Gas Safe registered engineer will inspect the burner, heat exchanger, and flue, check all safety controls, measure combustion efficiency, and clean components as required. You will receive a boiler service certificate on completion. If a minor adjustment is needed during the service, we carry it out at the same visit.

Signs your boiler may need replacing rather than repairing include: it is more than 12-15 years old; you are calling for repairs more than once a year; energy bills have risen without explanation; there are unusual noises; the flame is yellow or orange rather than blue; or your engineer has advised replacement is more cost-effective. Modern boilers are significantly more efficient than those installed before 2010.

A combi (combination) boiler provides central heating and hot water on demand from a single unit — no separate cylinder or cold water tank needed. It is ideal for smaller properties with one bathroom. A system boiler works with a separate hot water cylinder but no cold water tank, making it better suited to larger homes with multiple bathrooms. Heat-only (conventional) boilers work with both a cylinder and cold water tanks — common in older Devon properties, particularly those with Rayburn or AGA-style heating.

By law, all work on gas appliances — boilers, gas fires, cookers, and gas central heating — must be carried out by a Gas Safe registered engineer. This covers installation, repair, service, and safety checks. Unregistered gas work is illegal, dangerous, and will invalidate your home insurance. You can verify any engineer's registration at gassaferegister.co.uk. All our gas engineers are fully Gas Safe registered.

A plumber handles cold and hot water systems — pipes, taps, tanks, and drainage. A heating engineer specialises in central heating systems, boilers, radiators, and underfloor heating. Many plumbers in Devon are dual-qualified, covering both. Our engineers are Gas Safe registered and handle both disciplines, so you do not need to call two separate contractors for boiler and plumbing issues.

A power flush forces a high-pressure chemical solution through your central heating system to remove sludge, scale, and rust. This improves heating efficiency and extends boiler life. Signs you may need one include cold spots on radiators, noisy boilers, and slow-heating rooms. A power flush on a typical 8-10 radiator system in Devon costs approximately £300-£500 and takes 4-6 hours.

Common signs of a water leak include: unexplained rise in your water bill; damp patches on walls, ceilings, or floors; sound of running water when all taps are off; drop in water pressure; mould or mildew in normally dry areas; soft or sunken flooring; and a water meter turning when no water is in use. Many leaks in older Devon stone properties occur in buried pipework — we use acoustic and thermal detection to locate them without unnecessary excavation.

A CCTV drain survey passes a small HD camera through your drainage pipes to inspect their condition from the inside. The camera records footage showing cracks, root infiltration, displaced joints, blockages, and scale build-up. A CCTV survey is particularly recommended when buying a property, when drains block repeatedly, before drainage works, and when requesting a repair quote. Many older Devon properties have clay pipe drainage that benefits from regular inspection.

A qualified plumber can clear most drain blockages — blocked sinks, toilets, outside gullies, and main drainage runs. We carry drain rods and high-pressure jetting equipment for this purpose. For more complex issues such as collapsed pipes, root infiltration, or shared drainage disputes, CCTV survey and specialist equipment may be needed. We cover all these scenarios, so you only need to make one call.

Older Devon properties — particularly stone farmhouses and Victorian terraces in Tavistock — most commonly suffer drain blockages due to: tree root infiltration into ageing clay pipes; displaced pipe joints from ground movement; fat and grease build-up in kitchen drains; accumulated scale; heavy autumn leaf fall blocking external gullies; and flushing of wipes or sanitary products. Properties with septic tanks face additional risks of soakaway saturation during heavy rainfall.

Drain rodding uses flexible rods pushed manually through a pipe to break up or push a blockage. It works for soft blockages close to an access point but cannot clear grease build-up, scale, or root infiltration. High-pressure drain jetting forces water at up to 4,000 PSI through the pipe, scouring walls clean and flushing all debris away. Jetting is more thorough, more effective on stubborn blockages, and leaves pipes in better condition.

You are responsible for drains within the boundary of your property (your private lateral drain). South West Water is responsible for shared sewers — drains serving two or more properties. In practice the boundary can be unclear in older Devon properties. If the blockage is within your boundary, you arrange and pay for clearance. If it is on the shared sewer, South West Water should deal with it. We can advise on this after inspecting your system.

Drain jetting in Devon typically costs £100-£250 for a domestic property, depending on the pipe run length and difficulty of access. This includes a flow test after jetting to confirm the drain is clear. We provide a fixed price before starting work. Commercial properties or longer drain runs are quoted individually.

A basic bathroom installation — replacing an existing suite — typically takes 3-5 days. A full bathroom renovation with new tiling, floor, and all fixtures usually takes 7-10 working days. The timeline depends on the scope of work, whether any structural changes are needed, and materials delivery. We provide a detailed programme when quoting so you know exactly what to expect.

Yes. Many rural Devon properties are on gravity-fed or low-pressure water systems. We design bathroom installations around your actual water pressure — this may mean installing a pump-assisted shower, a pressurised hot water cylinder, or a different shower type than you would find in an urban property. We always survey your water supply before specifying fittings to ensure everything works correctly once installed.

A Rayburn is a range cooker that also provides central heating and hot water — widely used in Devon farmhouses and rural properties. Like an AGA, it runs continuously and heats from a central flue. Rayburns can run on oil, gas, or solid fuel and require annual servicing by a qualified engineer who understands their specific components. We service Rayburns and AGAs across the Tavistock area, including remote rural properties.

Yes. We cover properties on and around Dartmoor National Park within our 20-mile radius from Tavistock. This includes farms, smallholdings, and rural cottages in the national park itself. Response times to remote Dartmoor locations may be longer than to town-centre addresses. Please request a quote with your postcode and we will confirm coverage and provide an honest estimated arrival time.

The official way to check any engineer is via the Gas Safe Register at gassaferegister.co.uk — search by company name or engineer licence number. All legitimate Gas Safe engineers carry an ID card showing their licence number and the appliances they are qualified to work on. We are fully Gas Safe registered and can provide our licence number on request. Never allow unregistered gas work — it is illegal and dangerous.
