Homeowners, landlords and letting agents. ### When you need it As soon as you notice the fault. Small issues become expensive ones fast — a leak that drops system pressure will eventually damage the pump, the PCB or the heat exchanger. ### Why professional help matters There's a reason ex-British Gas trained engineers with 38+ years on the tools cost the same as a first-year fitter on a callout: you get the right diagnosis first time, and you don't pay for parts you didn't need. Guesswork is the most expensive way to repair a boiler. ## The cost of leaving it A boiler fault rarely stays small. Ignoring an F-code, a pressure drop or a noise usually means paying twice — once for the damage that follows, and once for the original fault. ### What can go wrong - A slow leak inside the boiler will corrode the pump, PCB and heat exchanger — turning a £150 repair into a £600+ one. - Repeated lockouts stress the ignition and gas valve, both of which are among the most expensive parts to replace. - A blocked condensate in winter freezes and shuts the boiler down completely — often on the coldest night of the year. - No hot water in a rented property can put a landlord in breach of their repair obligations within 24 hours. ### Common mistakes we see - Repressurising the boiler again and again without finding the leak — you're masking the fault while damage continues. - Letting a non-Gas Safe handyman 'take a look' — anything gas-side must be worked on by a Gas Safe registered engineer. - Accepting a diagnosis without a written price for the part and labour before work starts. - Buying parts online to save money — many manufacturers will void warranty on non-genuine parts fitted by a third party. ## Our process A clear, repeatable system — the same on every job, whether you're a homeowner or a landlord with a portfolio. 1. 01 ### Call Matt directly No call centre, no scripts. Matt takes the call, gets the symptoms, boiler make and model, and gives a realistic ETA. 2. 02 ### On-site diagnosis Full fault-find using manufacturer diagnostics — combustion analyser, multimeter, pressure gauges — not guesswork. 3. 03 ### Fixed price to fix Clear explanation of what's wrong and why, with a written price before any work starts. Nothing done without your say-so. 4. 04 ### Repair completed Where the part is on the van, repair done the same visit. Otherwise sourced the same day or next day and fitted at a time that suits you. 5. 05 ### Tested and guaranteed Full flue gas analysis, gas tightness test and controls check. Workmanship guaranteed for 12 months. ## What you get ### Right diagnosis, first time 38+ years on the tools means fewer parts changed 'just to see' and a lower final bill. ### No call-out fee You don't pay just for us to turn up. You pay for the fix. ### Priced before work starts Written fixed price for the repair. No open-ended hourly billing on straightforward faults. ### One-hour typical response Matt answers emergency calls personally, often on-site within the hour across our service area. ### Genuine manufacturer parts Protects your existing warranty and lasts longer than pattern parts. ### Backed by 12-month guarantee All workmanship guaranteed for a year, in writing. ## Recent boiler repair & breakdowns work Photos from real jobs completed by Matt and the Premier Heating team.

Common faults we see every week: ### Pressure loss and leaks If your pressure gauge keeps dropping and you're topping the filling loop up more than once a month, you have a leak. It might be at a radiator valve, a pipe joint, the auto-air-vent, the expansion vessel or inside the boiler. We pressure-test the system, isolate the leak zone, fix it once and refill with fresh inhibitor. ### Error codes and lockouts F22, F75, F1, EA, E133 — every manufacturer has its own dialect. We plug in the boiler diagnostics, read the fault history and correlate it with combustion readings and pressure data. That tells us whether you have a genuine part failure, a system water problem, a flue or condensate issue, or a controls fault. ### No hot water / no heating Common causes are a stuck diverter valve, a failed pump, a knackered PCB, a blocked plate heat exchanger or a scaled-up DHW sensor. The fix is usually the cheapest of these — if the diagnosis is right. ### Noisy boiler (kettling, banging, whistling) Kettling is almost always limescale or sludge on the main heat exchanger. That points to system water quality and often a powerflush. Banging pipes are usually air, expansion or clipping issues. We solve the cause, not just the symptom. ### Landlord and letting-agent repairs We work with landlords across Watford and Hertfordshire and can coordinate access with tenants directly. Invoices are itemised and suitable for management-company records. ## Frequently asked questions Do you charge a call-out fee? No. There is no call-out fee.
