Trade work in Bromley: interwar suburbs, owner-occupiers and London's biggest patch

Bromley is London's largest borough by area, and most of it is houses owned by the people who live in them. For plumbers, electricians, roofers, builders, landscapers and every other trade, that makes it a market built on planned, owner-funded jobs rather than quick call-outs alone.

Built between the wars

Bromley became a municipal borough in 1903 and joined Greater London in 1965, but much of what trades work on today went up in between. Hayes alone grew from 222 houses in 1921 to about 2,150 by 1939. Interwar semis and detached houses like these are typical candidates for boiler upgrades, roof repairs and replacements, and hip-to-gable or dormer loft conversions.

Owners, not landlords

68.5% of Bromley's 135,828 households are owner occupied, the highest share of any London borough we have researched. 17.4% rent privately (about 23,700 homes) and 13.2% rent from a council or housing association. When the customer is the owner, reviews and photos of finished jobs on your Google profile are worth investing in. We can set up and run that Google profile for you, so the reviews and photos keep working while you are on a job.

Heating and electrics

82.2% of homes heat with mains gas only, the highest share in our London research, so boiler repair, servicing and replacement is the core of the plumbing and heating market. On the electrical side, consumer unit changes, new circuits and bathroom work are notifiable under Part P, and landlords, now including social landlords since December 2025, need the electrics inspected at least every five years.

What Bromley searches for

Our Keyword Planner research (August 2025 to July 2026) puts plumber searches in Google's 1,000 to 10,000 a month range, the busiest of any trade we tested in Bromley. Electrician, roofer, builder, loft conversion, kitchen fitter, boiler repair and emergency plumber searches each sit in the 100 to 1,000 range, every month.

Roofs and lofts: the planning catch

Bromley has 47 conservation areas, including Bromley Town Centre, Shortlands Village and Chislehurst Road. On top of those, Article 4 directions apply in named areas, including parts of Beckenham, Chislehurst and Bickley, Petts Wood, Penge, Park Langley, West Wickham and Biggin Hill, and some of them remove permitted development rights for roof alterations and upward extensions. The council does not give informal advice on whether work is permitted development and points owners to a lawful development certificate instead, so check the address on the council's Article 4 map before pricing a loft or roof. Knowing these rules wins work, and we can turn your past jobs in these areas into project pages that prove it.

New homes and town centres

The London Plan sets Bromley a target of 7,740 new homes in the ten years to 2028/29, 3,790 of them on small sites such as infill plots and conversions. Bromley Town Centre is a Metropolitan Centre with Opportunity Area status, and Orpington is a Major Centre. The council's Economic Development Strategy counted around 15,300 businesses in 2020, more than 86% of them employing fewer than five people.

Ground conditions

Historic England's review of Bromley records London Clay under the north and north-west of the borough and chalk under the south and east, rising to the North Downs, with Thanet Formation sand, silt and clay where the two meet. River gravels and alluvium follow the Ravensbourne, the Cray, the Beck and the Pool. Clay shrinks as it dries and swells when it gets wet, and that movement can lead to subsidence. That kind of local ground knowledge is worth making visible, and we can help your website show the jobs you have done on it.

Where the work is

Getting found here

Bromley is big, so pick the parts you actually cover and name them on your website and Google profile. An owner in Petts Wood searching for a loft conversion wants to see Petts Wood, not just "South London". Building a page for each area and keeping your profile current takes time, so let us do it: we write the pages, look after your Google profile and run ads in the places you choose.
