boiler installs in Theydon Bois: 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.
Which boiler brand do you recommend?▾
Worcester Bosch and Vaillant for long warranties and parts availability; Ideal Logic Max for budget-conscious installs. We'll explain trade-offs honestly.
How long does a boiler install take?▾
A straight combi swap is usually one day. A boiler relocation, conversion, or full system change is typically 1–3 days.
