Annual service
Strip, clean, test, and record. Manufacturer warranties usually expect this every 12 months.
Service&repair
Keep the plant honest.
Heating services
A service is not a sticker. It is a combustion check, a look at the heat exchanger, a condensate that still runs, and controls that do what the homeowner thinks they do. Wales Heat matches annual services and breakdowns to local Gas Safe engineers so you are not waiting on a national diary.
Landlord certificates (CP12) sit on the same book. If you let property in more than one authority, say so on the brief and we will match coverage rather than sending three different firms without asking.
Breakdowns
No heat, no hot water, leaking valves, locked-out boards. Tell us the make if you know it.
Landlord certs
Gas safety records for rented homes, with copies for you and the tenant trail.
Powerflush
When sludge is killing the combi, a flush and a filter can be cheaper than another board.
When to repair vs replace
Age, parts availability, and the rest of the system decide it. A 15-year combi with a cracked heat exchanger is usually a replacement conversation. A two-year unit with a failed pump is a repair. The matched engineer will say which, in writing, before you spend.
