FAQ

Common questions

How long does a boiler installation take?+

Most straightforward combi boiler swaps are completed in a single day. System or regular boiler installs, or moves to a new location, typically take one to two days.

Which brands do you install?+

We install and service Worcester Bosch, Vaillant and Ideal Heating boilers, with manufacturer-backed guarantees of up to 12 years depending on the model and maintenance plan.

Do you offer emergency repairs?+

Yes — our response target for existing customers is the same week, and we carry common parts on our vans to fix most faults on the first visit.

Is my Victorian terrace a problem?+

No — most of our installs are in Victorian and Edwardian terraces across London. We plan flue routes and pipework around period features rather than the other way round.
