Most builders charge about £1000 – £1,200 per square meter for a basic single storey extension; this will be finished, plastered with electrics, radiators and standard windows and doors. The price will be increased when you add things like bi-fold doors, Velux roof windows, under-floor heating or any complicated knock through requiring steel-work.
Neil will be able to advise you on a suitable budget for the work that you are planning.
Please contact any of our recommended builders listed below. They will be happy to provide a quote for any work you are planning, or if you’d prefer we can contact them on your behalf.
They will come out to see you so you can meet them, discuss the work and they can answer any questions you may have. Tell them if you want to do any of the work yourself, or you want extra work like UPVC soffits and fascias or gutter replacement, so they can itemise the quote and you know what has been included when comparing quotes.
Always ask for references and even to see some of their work. Also ask about availability and time scales to see if it fits with when you want the work done and ensure that you are happy with any deposit required and payment terms. They will contact me if there is anything they are not sure about from the plans and also whilst they are working on site if they need me to ensure things run smoothly for you.
You can see examples of work by some of our recommended builders in our project portfolio.
You may want to choose a builder you have used before or recommended to you by someone you know. If you choose to do this we will still provide the same support during the build. Even if a builder is recommended by a friend, you should still follow the steps above and ask to see examples of previous projects.
