How it works

Three steps to your fixed price.

  1. 1

    You answer six quick questions

    Property type, bedrooms, bathrooms, hot water cylinder yes or no, current fuel and how to reach you. Under a minute, no phone tag.

  2. 2

    We survey the job, free

    A qualified Gas Safe engineer assesses the whole job in person, because that is the only way to price it properly. No salesman, no pressure.

  3. 3

    Fixed price by email, around one working day

    The price we email is the price you pay on installation day. No surprise extras, no salesman at your kitchen table, no "the survey changed the price".

Most quotes land inside a working day. Got a question, or need an answer sooner? Just call us on 0800 980 6018 and talk to a real person in our Bradford office.

Sound right? Six quick questions, a free survey by a qualified engineer, then your fixed price by email within around one working day.
