According to a 2023 report published by Nationwide, home improvements that add floor area, such as a loft conversion, can add up to 25% to the value of your property. Adding an extra bedroom can add up to 15% to the value and an extra bathroom adds up to 6% to the value of a home. Since their last survey, back in 2016, and considering the “Race for Space” driven by the pandemic in 2020 and 2021, the value added by increasing the floor space appears to have continued to improve and is now around 25% rather than 23% previously. The report found that having more usable space is generally thought to be consistent with better quality accommodation. Adding a third bedroom to a two-bedroom house can increase the value by around 14% and the Nationwide research also found that adding a second bathroom to be very favourable to adding value, potentially increasing property value by 6% alone.

A loft conversion; a luxury or necessity?

One of the big questions everyone asks prior to embarking on a loft conversion journey is: is it a luxury or a necessity? In our experience, it is a necessity. Many homeowners we work for originally bought their home with the intention of growing their family over time or as a professional with a large portion of their week working from home but who love where they live and want to stay there. Aside from making more space in your home, a loft conversion will make also your home more energy efficient. Energy costs are likely to remain a concern for households in the near future and making your home more energy efficient with a new loft conversion is a great means of lowering your energy consumption and insulating your property to be more efficient. The Government have sent a mandate to update the energy efficiency of as many homes as possible to a ‘C’ rating by 2035. They have recognised that over the past 10 years the energy efficiency in homes where improvements including loft conversion have been carried out have increased with better loft and cavity wall insulation. All of this has a positive impact on the overall value of your home.

There have been many external factors recently that have impacted the costs of a loft conversion in London. These include inflation impacting material costs and labour costs and labour availability. The FMB state of the trade Q1 2024 reports that materials costs continue to rise but at a slightly slower pace than in 2022 and early 2023. This is good news as the material costs are becoming more predictable and less likely to increase in the short-term making it better for pricing your loft conversion.

Comprehensive Planning

One of the most important things when it comes to managing the cost of a loft conversion is planning. A lack of planning or slow decision making can lead to added or unforeseen costs further down the line. We aim to provide you with the most accurate costs from the very beginning of your loft conversion journey. Alongside you, we meticulously plan every element of your loft conversion project at the very beginning. We work to be transparent, communicate effectively and get the pricing right each and every time.

Before the build gets started, our team will work with you to finalise designs, secure all necessary permits, licences and all regulatory requirements. Elements that must be considered when planning out your project are:

1. Structural requirements - structural integrity needed for your loft conversion including, steel beams needed, floor reinforcement or changes, staircase position and reinforcement, roof alterations.
2. Layout – survey to confirm precise layout and dimensions of the loft including things like placement of walls, room locations, built-in storage and large furniture items.
3. Windows and natural light – deciding on the type, size and placement of windows, roof lights and Velux windows. Also, other things to consider are juliette balcony and French doors.
4. Electrical and plumbing plans – where to place and what kind of light switches, light fittings, electrical outlets. Routing of pluming for bathrooms and placement and type of sanitary ware.
5. Heating and cooling – planning for heating with radiator placement and potentially cooling with the addition of aircon systems.
6. Insulation and Ventilation – ensure adequate insulation and ventilation plans are in place to meeting building regulations and provide comfort.
7. Interior design elements – choosing paint colours, finishings, tiles and other materials and specifying / planning positions.
8. Technology and communication – plan for your technology needs including internet connections, home office set up or home entertainment systems
9. Permissions and regulations – ensuring all necessary permits and permissions are in place prior to commencing building works

Do you need a contingency fund?

We work to be transparent, communicate effectively and get the pricing right each and every time. However, we have worked on hundreds of London homes and understand that sometimes, there are unforeseen issues that arise, particularly in older properties. Issues that generally get uncovered through a renovation are plumbing or electrics need updating, failing brickwork on chimney’s that needs to be replaced, repointing around original chimney stacks on the roof etc. The typical contingency fund recommendation is between 10% and 20% of the project cost.
