Prices below are typical ranges for 2026 in the UK and eurozone; your local dealer’s rates will vary with region and overhead, but these give you a baseline to judge a quote against.
What a “service” actually covers
A basic dealer service on a petrol brush cutter is not a repair — it’s the preventative work most owners either don’t have time for or don’t have the tools for. A standard service typically includes:
- Air filter clean or replacement
- Spark plug check, clean or replace, and gap set to spec (typically ~0.5 mm)
- Carburettor external clean and idle adjustment (typically targeting 2,800-3,000 rpm)
- Fuel line and filter inspection
- Spark arrestor clean (if fitted)
- Gearhead grease check and top-up
- Full fastener torque check
- Cutting attachment and guard inspection
- General clean-down and a running test under load
That’s the “nothing’s actually broken” service. If the technician finds a fault during it — a cracked fuel line, a fouled plug that won’t hold a spark, a carburettor that needs more than an external clean — that becomes a separate repair line on the invoice, quoted before the work proceeds.
Typical service prices
| Service level | What’s included | Typical price (GBP) | Typical price (EUR) |
|---|---|---|---|
| Basic/express service | Filter, plug, external clean, idle check | £35-55 | €40-65 |
| Standard annual service | Basic + carb clean, fuel lines, spark arrestor, gearhead grease | £55-90 | €65-105 |
| Full service (100-hour/annual) | Standard + compression test, full carb inspection, torque check | £90-140 | €105-165 |
| Winter storage service | Fuel-out, cylinder fogging, clean, storage prep | £30-50 | €35-60 |
These are labour-inclusive prices assuming no parts need replacing beyond a plug or basic filter. Add parts cost on top for anything else found faulty.
Common repair costs
Repairs sit on top of (or instead of) a service, and this is where costs spread widely because labour time varies with how accessible the part is and whether the fault is straightforward or takes real diagnostic time.
| Repair | Typical labour + parts (GBP) | Typical labour + parts (EUR) | Notes |
|---|---|---|---|
| Carburettor clean (external) | £25-45 | €30-50 | Often bundled into a standard service |
| Carburettor rebuild kit fitted | £45-90 | €55-105 | Gaskets, diaphragms, and labour to strip/reset |
| Full carburettor replacement | £60-130 | €70-150 | When a rebuild won’t hold or the body is damaged |
| Ignition coil replacement | £50-100 | €60-115 | Part cost varies more than labour here |
| Recoil starter (cord/spring) repair | £25-50 | €30-60 | Cord replacement alone is cheaper than a full assembly |
| Recoil starter assembly replacement | £45-85 | €55-100 | If the housing or pawls are damaged, not just the cord |
| Clutch/drum replacement | £40-90 | €45-105 | Common after a jammed attachment or dropped machine |
| Fuel line and primer bulb replacement | £20-40 | €25-45 | Cheap part, mostly labour to access |
| Piston and cylinder work | £120-250+ | €140-290+ | Often approaches the cost of a new mid-range machine |
| Gearhead bearing/seal replacement | £40-80 | €45-95 | Depends on whether the housing needs splitting |
Safety note: ignition and carburettor work involves fuel system components and, on some engines, working near a live spark source. If you’re not confident isolating the fuel supply and disconnecting the plug lead before starting, this is dealer territory, not a driveway job.
DIY parts costs, if you’re doing it yourself
If you’re comfortable with basic tools, several of the cheaper jobs above are within reach without dealer labour rates. Typical part-only prices:
- Spark plug: £3-8 / €4-9
- Air filter (foam or paper): £4-12 / €5-14
- Fuel line and filter kit: £5-12 / €6-14
- Carburettor rebuild/gasket kit: £8-20 / €9-23
- Recoil starter cord and pawl kit: £6-15 / €7-18
- Complete aftermarket carburettor: £15-35 / €18-40
- Ignition coil: £15-35 / €18-40
Doing your own carb clean or spark plug change (see our guides on cleaning a brush cutter carburettor and changing a brush cutter spark plug) can cut a £60-90 dealer bill down to under £20 in parts, if you’re willing to put in the time and follow the correct idle and gap settings.
The repair-vs-replace threshold
The rule of thumb most independent mechanics use: if a single repair quote exceeds 40-50% of the machine’s original purchase price, or if two separate faults need addressing at once (say, a carburettor rebuild plus a coil), it’s worth pricing a replacement before committing.
Work through it like this:
- Get the quote in writing, itemised by parts and labour, before authorising work.
- Add up the age-adjusted value. A machine that’s five years old and needed a coil last year is a different proposition to a two-year-old machine with its first fault.
- Check for compounding faults. A worn recoil often accompanies a tired engine generally; a single symptom rarely means a single isolated fault on an older machine.
- Weigh against a compression test result, if one’s been done. Low compression on an ageing two-stroke usually means the engine’s remaining life is short regardless of what else gets fixed.
- Factor in machine class. A budget homeowner unit nearing a £150 repair on a machine that cost £180 new is a clear replace. A professional-grade machine with a £150 repair bill on a £500+ purchase is usually still worth fixing.
Safety note: never let cost pressure push you into skipping a compression test or ignoring a suspected cracked crankcase seal — running a machine with a confirmed internal fault risks sudden engine seizure, which can happen mid-cut while the blade is still spinning down.
When to call a dealer vs sort it yourself
Call a dealer when: the fault involves ignition timing, a suspected cracked crankcase or piston damage, a carburettor that won’t hold adjustment after a clean, or any fault you can’t isolate from the symptoms alone. Sort it yourself when: it’s routine (filter, plug, external clean), the part is cheap and accessible (fuel line, recoil cord), or you’ve already confirmed the fault via a basic diagnostic (no spark with plug removed and grounded, visible fuel leak at a specific fitting).
Quick checklist before booking a service or repair
- Get an itemised quote, not just a total figure, before authorising work
- Ask if the diagnostic fee is deducted from the final bill
- Compare the quote against 40-50% of the machine’s original price
- Check whether the machine is still within any manufacturer warranty
- Ask specifically what “service” includes at that dealer — it varies
- Price a DIY parts-only fix first for routine jobs (filter, plug, fuel line)
- Factor in machine age and any prior repairs before committing to a big bill
