Home improvement lives on in busy property market as Brits apply to extend their homes by over 1.5 million sq metres in lockdown

  • Analysis of local authority planning data commissioned by Santander shows UK homeowners applied for over 60,000 extensions and conversions to improve their homes in the 13 weeks of lockdown 1
  • New research by Santander also reveals that Covid-19 and lockdown prompted two in five (40%) homeowners to bring forward their home improvement plans 2
  • Three in five (61%) homeowners carried out a DIY or renovation project during lockdown
  • The bank’s research suggests that lockdown will also trigger a boom in home improvements, as four in five (81%) homeowners plan to make changes to their homes in the next 12 months


While post-lockdown has seen a boom in property sales, new analysis by Santander UK has revealed that UK homeowners are also looking to improve their homes, as they submitted 61,682 planning applications in the 13 weeks of lockdown. If completed, this work would add more than 1.5 million square metres of space to Britain’s existing housing stock, the equivalent of 214 football pitches 3 or larger than Hyde Park in London.

According to Santander’s analysis of local authority planning applications, compiled by construction industry analysts Barbour ABI, homeowners submitted plans this year to extend their homes by an average of 24.875 sq metres each4. The combined total cost of this work is an estimated £1.9 billion pounds5.

Despite the uncertainty brought by Covid-19, and a lot of people now looking to move property, it seems Britain remains home to a community of improvers, who have ploughed ahead with working on their property. Research by Santander, among more than 2,000 UK homeowners, suggests that for two in five (40%), the pandemic accelerated home improvement plans and inspired future projects both small and large.

Prior to Covid-19, one in five (18%) homeowners had planned to complete larger scale home improvement or renovation works on their property in the next 12 months6, however, this has now increased to one in three (32%) according to new figures.

While social distancing measures impacted plans for some, just a tiny 4% of larger scale home renovation plans were cancelled altogether.

The figures show that three fifths (61%) of homeowners carried out a DIY or renovation project during the March to May period, with two in five (39%) saying that spending more time at home during lockdown made them aware of the changes they wanted to make. The most popular changes in lockdown took place outside, with over half (53%) of homeowners having done some work on their garden. Meanwhile, projects inside homes included decorating a room (25%), repurposing a room (8%) and creating a home office space (7%).

Graham Sellar, Head of Mortgage Development, Santander UK commented: “The entire nation spent increased time in their homes during the pandemic, and some may have found they have savings accumulated thanks to lockdown forcing a significant change in spending habits. So it’s no surprise homeowners picked up paint brushes and got to work on their homes. Whether it was finally getting around to neglected DIY projects to ready their home for selling, or planning a bigger extension or conversion to give them more space, our research shows that few homes have emerged from the pandemic as they were.”

With new UK Government planning rules set to come into effect from next month7, and the strong property market, the home renovation boom looks set to continue as people create more living space in their current home or start to move into and carry out work on their new homes. This is shown in the research as over half (54%) of homeowners said they thought the pandemic would result in more people making plans to change their homes both inside and out, and indeed four in five (81%) admit they now plan to make some kind of change to their home in the next 12 months.

Lisa Dawson, award-winning home and interiors writer and blogger, commented: "For many of us, lockdown has provided the time and motivation to complete DIY jobs around the house, or rethink how our space works for us. If you’re thinking of changing your home, there are some really easy ways to get started:

Top Three Tips
1. Find Your Style.  Look online to nail down what your core style. Save images that you like and you’ll start to see a theme coming through – it might be natural materials, bright colours or a minimalist vibe.

2. Plan Well.  Look at the bones of your room – does it have any lovely features?  Big windows, a fireplace or a beautiful wooden floor should be your starting point.  Make the most of what you already have.

3. Don’t Rush.  Rome wasn’t built in a day - Add pieces slowly and carefully and source exactly what you are looking for instead of rushing to fill a space. If you love all of your possessions, then your home will make you happy which is the ultimate aim.”

Large scale development

For those that have completed conversions and extensions, past research shows one in five (20%) homeowners did so because it was cheaper than moving, while over a tenth (14%) said they wanted to stay in their current home as it is sentimental to them. Other reasons cited were that renovating was perceived to be “less hassle” than moving, while a small percentage pointed to the lack of suitable or affordable housing in the area they wanted to buy (4%).
Meanwhile, the average budget for planned home improvement projects in the next 12 months sits at £5,600, with one in ten having increased the sum during Covid-19. The majority of people have historically funded these improvement works with savings, however, one in ten used additional borrowing on their mortgage to complete the works.

3. Each football pitch measure 7,140 sq metres.
4. The actual figure is likely to be higher as Santander’s analysis does not include projects completed under permitted development.
5. Santander also sourced average size and costs of various extension projects sourced from MyBuild.co.uk, multiplied by the number recorded in the Barbour ABI data.
6. Research is drawn from a survey conducted by Opinium research between the 7th – 13th February 2020. The base size was 2,082 UK homeowners.
7. The new rules will allow homeowners to add up to two storeys, up to a height of 18 metres, to their home through a fast-track approval process. Homeowners will also be able to demolish and rebuild unused buildings without needing full planning permission to do so.
