boiler repairs in Chelmsford: questions we get a lot
How long does a quote take?▾
Most quotes go out within 24 hours of the survey, sometimes same-day if it's a straight swap.
Will you match other quotes?▾
We won't price-match for the sake of winning the job, but we will explain exactly what's included in our quote vs theirs — that's usually where the difference is.
Is it worth repairing an old boiler?▾
Honest answer: if it's over 12 years old and the repair is more than £400, replacement usually makes more financial sense. We'll lay out both options without pressure.
How fast can you come out?▾
We aim for same-day on no-heat and no-hot-water situations. Tell us when you call if anyone elderly or with young children is in the property — we prioritise.
