boiler servicing in Knebworth: questions we get a lot
Why don't you publish fixed prices online?▾
Because every job is different. The "from £1,499" you see on national sites almost never includes flue, system flush, controls, or any pipework changes — the bits that always come up.
Do you do landlord CP12 certificates?▾
Yes — combined service + CP12 packages available, with bulk pricing for landlords with multiple properties.
How often should a boiler be serviced?▾
Once a year. It's almost always required to keep the manufacturer's warranty valid, and it catches small issues before they become breakdowns.
