Understand it before you decide
Investigate first.
Agree the next step together.
A boiler problem doesn’t automatically mean a replacement boiler. The first step is to investigate what’s happening and explain the findings.
- No heating or hot water
- Boiler losing pressure or repeatedly locking out
- A fault code on the display
- Leaks, unusual noises or unreliable operation
- Heating controls or radiators not behaving as expected
Where a repair is possible within the booked time, it can be carried out. Any chargeable parts, extra labour or further visits are quoted before you approve them.

Arrange the right visit★★★★★
“Great communication from the very beginning and even on the day of the appointment, I knew exactly when he was arriving.”Dean Cook · Google review · March 2026 · excerptRead all Google reviews
Useful details to include.
Your boiler make and model, an error code if shown, what has stopped working and when it started. A description is enough to start; you don’t need to diagnose it.
Ask a question before bookingLeave the internal work to an engineer.
Do not remove the casing or attempt repairs inside the boiler. If you suspect it is unsafe, stop using it and seek the appropriate help.
Gas safety & emergency guidanceBefore you arrange a visit
Repair questions.
Straight answers.
The initial visit, additional work and how to prepare.
What does the £125 repair visit include?
£125 includes fault diagnosis and up to 90 minutes onsite for repairs possible during the visit. Any parts, materials, additional time or return visit are quoted for your approval.
What happens if you cannot fix it on the first visit?
You’ll receive an explanation of the findings and a quote for any parts or further work. Where a return visit is needed, the next step is agreed with you.
Can you come today?
Check online booking for available appointments in your area. For a gas smell or suspected carbon monoxide, use the emergency guidance rather than booking a routine visit.
Should I book a service if the boiler has stopped?
No. Select a diagnosis / repair visit for an existing fault. You can arrange routine servicing separately or discuss it once the fault is understood.
Do I need to know what is wrong before booking?
No. Describe what you are noticing: for example, no hot water, falling pressure, a leak or an error code. A photograph of the display can be useful. Do not remove the boiler casing or attempt internal repairs.
What if I smell gas or the CO alarm sounds?
Use the emergency guidance immediately, not the ordinary booking flow. Get outside into fresh air and call 0800 111 999 from outside. For immediate danger or serious illness, call 999.
