Kitchen Renovation New Barnet

GS Renovation fits kitchens throughout New Barnet, in its flats and semis and in the back addition of a Victorian terrace, where the room is long, narrow and dark, or a side return infill has just made it twice the size. We handle the structural opening, drainage, electrics and units as one project rather than four separate visits.

In New Barnet, a kitchen renovation typically costs £18,000 to £60,000 or more from design to fitting (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in New Barnet: we carry the strip-out, services and fit as one contract, with the electrics certified by a registered electrician.

Kitchens in a New Barnet back addition

A terrace kitchen in EN4 is typically a galley in the back addition, with a door at one end, a window over the sink and a chimney breast that once took a range and now takes nothing at all. Opening that breast up gives a proper recess for a range cooker, and it is the natural place to run the extraction because the flue is already there. Whether the breast can be opened out depends on what is above it, which is a question for the structural engineer rather than the kitchen fitter.

Extraction is where terrace kitchens are routinely bodged. A recirculating hood with a charcoal filter does very little about steam, and steam is what rots the window reveals in these rooms. Ducting out means 150mm rigid duct on the shortest run you can manage, with a proper hooded terminal, and in a narrow side return the terminal position has to be sensible relative to the neighbour's window rather than pointed straight at it. We set the duct route before the units are ordered, not after.

Housing in New Barnet

The valuation list shows roughly 10,670 homes in the New Barnet and Hadley Wood statistical areas, of which 17% are pre-1919, 32% interwar and 52% post-1945, split 50% flats to 50% houses. A kitchen sink in a flat in New Barnet has to stay within reach of the shared soil stack, which matters here because many homes are flats.

Kitchens over concrete floors and in newer New Barnet homes

In a post-war New Barnet house the kitchen usually sits on a concrete slab, and that decides what a new layout can do. Moving a sink or dishwasher away from the wall means a waste pipe chased into the slab at a steady fall, or boxed along the wall above floor level. Chasing a slab can cut through the damp proof membrane, which then has to be made good before the new floor goes down. With 52% of homes here built after 1945, we check the slab and the membrane before the island is drawn.

In New Barnet 11% of homes were built in 2000 or later, and some of those have whole-house ventilation, either continuous extract fans or a heat recovery system with ducts in the ceilings. A new cooker hood has to work with that system rather than against it. A powerful extractor in a sealed modern house can pull air back down a flue or disturb the balance of a heat recovery unit. Find the ventilation paperwork from the builder, and set the hood and its duct before the units are ordered.

Structure, services and flats across EN4

Where the kitchen is being opened into the rest of the house, the wall between the back addition and the main house comes out on a beam sized by a structural engineer, and the floor levels almost never match. The back addition often sits a step down, and a step in the middle of a kitchen floor is a nuisance for the next thirty years, so we resolve it in the screed or with a ply and batten overlay. Barnet Council building control inspects the beam and the bearings before anything is boarded over.

In a converted flat the constraints come from the lease as much as the Building Regulations. Moving a sink or a washing machine means a new waste run at a workable fall to an existing stack, and there is a limit to how far you can chase across a floor that forms someone else's ceiling. The freeholder's consent covers that. New circuits in a kitchen are notifiable under Part P, so a registered electrician certifies them or they are notified to building control, and we allow for the managing agent's hours and access rules in the programme.
