How our service works

Modular House Extensions is an introduction service. We do not design, manufacture, deliver or install extensions. We help people across Great Britain find a company that does.

What happens to an enquiry

  1. You send three things

    The postcode of the house, what you would like built and how a crane might reach it, then your name and how to contact you.

  2. We look for one firm

    A company that makes and installs modular extensions, covers your area and takes on jobs of your size.

  3. We give you its name

    By email or phone, normally within a working day. At that point the firm knows nothing about you.

  4. You choose

    Say yes and your enquiry goes to that firm, which arranges a survey and quotes. Say no and nothing is sent.

Who pays

The firm does. It pays us a fee for the introduction. You pay us nothing at any stage, and the fee is the same whether or not you go on to buy.

What we do not do

  • We do not quote for your job. Only a firm that has seen the house, the ground and the street can.
  • We do not take deposits or handle any money between you and a firm.
  • We do not pass your details to anyone before you agree, or to more than the one firm we named.
  • We do not send marketing emails or sell lists.

Your contract

If you go ahead, the contract, the guarantee and every payment are between you and the firm. Check its insurance, its references and its paperwork as you would for any builder. We have no connection with any manufacturer or builder whose name resembles ours.

The prices and guidance on this site

Prices are typical national ranges for 2026, including VAT, and the rules we describe come from GOV.UK, the Planning Portal, the Health and Safety Executive and the Scottish Government. Each page lists its sources. They are there to help you plan and to ask better questions. They are a guide, not a quote, and not legal advice.

Get a quote for your extension

Three short steps, about a minute. Start with the postcode so we know which firms can reach you.

This is a free introduction service, not a modular extension firm. We look for a firm that builds this type of extension where you live and tell you its name. Your details go to that firm only when you say yes.
