    FAQs

    • How much should I budget for a house extension?

    • The cost of a house extension in warrington typically ranges between £1,800 and £3,000+ per square metre, depending on the type of room and the level of finish required.

      Standard rooms generally fall within this range, while kitchens, bathrooms, lofts, and basements tend to cost more due to additional complexity and fittings.

      For single-storey extensions, the costs are as follows:

      A 20m² extension could cost between £40,000 and £60,000+.
      A 30m² extension might range from £60,000 to £90,000+.
      A larger 50m² extension could set you back between £100,000 and £150,000+.

      Larger extensions may benefit from economies of scale, slightly reducing the cost per square metre. To get an accurate estimate, it’s recommended to consult a builder or architect give us a call so we can give you a tailored quote.

    • How much can I extend my house without planning permission?

    • You can extend your house without planning permission under Permitted Development Rights, as long as the extension meets specific criteria:

      Single-storey rear extensions can extend up to 4 metres for detached houses and 3 metres for other properties.

      If part of the Neighbour Consultation Scheme, these limits increase to 8 metres for detached houses and 6 metres for others.

      Side extensions must be single-storey, no wider than half the width of the original house, and no taller than 4 metres.

      Extensions must not cover more than 50% of the land surrounding the original house.

      Keep in mind, these rules apply to most properties but not to listed buildings or homes in conservation areas.

    Reviews

    Louise King- April 2021

    Really pleased with our orangery style conservatory, looks more like an extension and has added space and value to our property.

    Lisa Hyland- February 2021

    Highly recommend Tony and his team. Excellent work throughout, beautiful windows and a patio door completed in great time . Cleanest workmen ever! Thank you to John and Gary who were here on the coldest days of the year. Kitchen next.

    Janet Galasso- February 2021

    I live in Maghull and did a lot of research and quotes before ordering from Allerton Windows in Bootle. I ordered double glazing for the front and sides of the house having already done the back a few years ago with another company (pre-covid). Hands down this is the best company.

    Michael Symington- October 2020
