Boiler installers and housing in London
Compact combi boilers suit London kitchens, where a cupboard is often the only space on offer. Listed buildings and conservation areas can limit where a flue terminal may go, so ask an installer to confirm the route before you choose a model.
Most London boiler jobs are in flats and terraces, where the boiler sits in a kitchen cupboard and the flue has to find an outside wall through a party structure. That makes a combi the usual choice, and it is why a flue route and access are checked at the survey rather than assumed.
London conversions are mostly flats and terraces where a cylinder and tanks take up space the household wants back. Moving a boiler may need a flue route through a party wall or past a neighbour, so ask the installer to confirm the route before you agree a date.
In London most boilers live in flats and terraces, often in a kitchen cupboard that is hard to reach. A service takes a little longer there, and a repair that needs a part can mean a second visit. Book early in autumn, because the busy weeks fill quickly.
Inner London is dominated by Victorian and Edwardian terraces and by conversions of them into flats, so most jobs involve a party wall and a neighbour. Outer London is largely interwar semi-detached, with substantial post-war blocks and a steady supply of recent high-density flats. Solid-wall construction is common inside the North and South Circular.
Planning and building rules in London
London has more conservation areas than any other region, and in much of the inner boroughs permitted development rights have been removed by Article 4 directions. Assume you need to check before changing anything visible from the street. The Party Wall etc. Act 1996 applies to most terraced and semi-detached work, and serving notice properly takes two months, so it belongs at the start of the programme rather than the end.
The weather
London is the driest part of the UK at roughly 600mm of rain a year, a little over half the UK average, so damp is less pressing here than almost anywhere else. Heat is the live problem instead: the urban heat island keeps the city several degrees warmer than the surrounding countryside on summer nights.
