Probably not double but definitely up by 50 % since 2020. Alot depends on what part of the country you are. An average conversion in the Midlands would range from 40k to 60k for average sized house.

I wouldn't say prices have doubled but in the london/ essex area the rates are around 45k to 65k.

Hi, i would not say double, but lots of variables, Spec and scope? What is the room going to being used as? or for?. Do you have PD rights if this was a new build? Sometimes controlled by original planning, and possibly developer. You will still have to satisfy building control, also lets think of the original 10 year warranty that exists, we don't want to compromise that. I would say in summary, costs have massively increased over last 5 years, whether or not 50%, in some cases yes in others no... but certainly by 40% plus

Thank you for your question. Construction costs have risen significantly since 2020 due to increased material prices, labour shortages and updated Building Regulations requirements. However, a straight doubling is not always accurate. A dormer loft conversion that cost around 50k in 2020 would more realistically sit in the 70k to 90k range today, depending on your location, specification and structural complexity. London and the South East tend to be at the higher end. We would strongly recommend obtaining at least three detailed, like-for-like quotations and comparing scope carefully rather than just headline price, to ensure you are getting a fair and compliant quote.

Hello 👋 ​The cost of a loft conversion has certainly increased significantly since 2020 due to the rising price of materials and labor, though it hasn't quite doubled. While a dormer conversion might have cost £50k five years ago, you should now realistically budget for a 50% increase, bringing the average price for a standard-sized conversion to between £65k and £75k. These figures typically include professional fees such as architect drawings and structural calculations. Prices can still vary based on your specific location and the complexity of the design, so getting a few updated local quotes is your best next step. ​Multitrademasters

Hi there I would try and get more quotes in place (6x), make sure everyone is quoting from the same layout, details and finish.. quotes can drift a lot if everyone isnt on the same page!.. Also i would try and use a “Loft conversion firm specialist” not a general builder. Hope this helps? Thanks russell Mtr lofts ltd
