Our process

Inspect

We assess symptoms and isolate the likely blockage point. Furthermore, we lift the nearest manhole or use CCTV access to confirm the location before any clearance work begins.

Resolve

We clear and clean drains using the right method for the issue. Therefore, you avoid both the under-clearing of repeat call-outs and the over-clearing of unnecessary work.

Prevent

We provide practical recommendations to reduce repeat callouts. As a result, our customers typically see year-on-year reductions in drainage costs after their first visit.

Boiler Repair — frequently asked questions

How much does boiler repair cost in Devon?

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.

How long does a boiler service take?

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.

How do I know if my boiler needs replacing?

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.

What is the difference between a combi boiler and a system boiler?

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.

When do I need a Gas Safe registered engineer?

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.
