Home renovation services in Chatham range from refitting a single room to stripping a property back to the brickwork and rebuilding it. A full renovation usually covers structural alterations, rewiring, replumbing, a new heating system, insulation upgrades, replastering, joinery, and new kitchens and bathrooms, all sequenced by one contractor so the trades are not tripping over each other. What you should expect from a main contractor is a single point of accountability, the building control application handled for you, and a realistic order of works agreed before anyone lifts a floorboard.
Two things make a Chatham renovation different from a generic one, the age of the property and the ward it sits in. The terraces around Brompton, Luton and Chatham Central were built at speed in the late nineteenth century for dockyard workers and their families, which means solid walls with no cavity, party walls on both sides, and services that have been patched and extended for well over a century. Medway Council has also confirmed Article 4 directions covering seven wards, so some conversions that used to happen automatically now need planning permission first.
Chatham’s housing stock decides the scope
Three broad types of property dominate, and each renovates differently.
The Victorian and Edwardian terraces in Brompton, Luton and Chatham Central were built for dockyard families. Solid brick walls, suspended timber ground floors, original slate damp proof courses where they survive at all, and lime plaster underneath whatever has been skimmed over it since. These are the properties where the survey work matters most, because what you find behind the plaster usually changes the budget.
The post-war estates around Walderslade and Lordswood are a different job entirely. Cavity walls, concrete floors in places, and services that are dated rather than antique. Renovations here are usually about layout, insulation and replacing tired systems rather than rescuing structure.
The waterfront developments at Chatham Maritime, St Mary’s Island and Chatham Waters are modern stock. Work here is more often about reconfiguring space and finishes, with leasehold consents to consider rather than damp and structure.
We’ve found that the single most expensive mistake in Chatham is pricing a Victorian terrace as though it were a 1960s semi. The two are not comparable jobs, and a quote that does not distinguish between them has not been properly considered.
The permissions that catch Chatham homeowners out
Most people assume internal renovation needs no permission. Often true, with important exceptions locally.
Medway Council’s Article 4 direction, changed in 2026, removes permitted development rights for converting a single family home in Class C3 into a small house in multiple occupation in Class C4 across seven wards. Chatham Central and Brompton, Fort Pitt and Luton are all on that list, alongside Gillingham North, Gillingham South, Strood North and Frindsbury, and Watling. If your renovation involves splitting a house into rooms let separately, that is now a planning application rather than an assumption.
Conservation area controls also bite harder than people expect. Chatham has several, including New Road, Maidstone Road, Brompton Lines and Chatham Historic Dockyard. Inside them you need permission to alter doors, windows and walls, and even minor changes such as external painting, and demolition of any part of a building needs consent. Replacing rotten sash windows with uPVC is the classic enforcement case.
Building control in Medway is worth knowing about too. It is run by the STG Building Control Partnership, based in Rochester, which delivers the service for Canterbury, Gravesham, Medway and Swale. From working with clients across our patch, that turns out to be useful, because we are based in Meopham inside Gravesham, so we are dealing with the same building control team at home as we are in Chatham. Knowing how a particular authority inspects, and at what stages they want to see the work, removes a surprising amount of friction from a programme.
Damp is the most misdiagnosed problem in Chatham terraces
Almost every Victorian terrace renovation we are called to includes damp somewhere in the brief, and the diagnosis is wrong more often than it is right.
In our experience, fixing the external causes of damp before touching the internal walls works better than starting with an injected chemical damp proof course because in most Chatham terraces the moisture is arriving from somewhere obvious once you look. A rear path or patio raised above the original slate damp proof course. Airbricks blocked or buried, so a suspended timber floor has nowhere to breathe. Cement render and modern masonry paint holding water inside a wall that was built to dry outwards. Injecting a chemical course into a wall that is wet for one of those reasons treats the symptom, and the replastering that follows fails within a couple of winters.
Get the ground levels, the rainwater goods and the ventilation right first, let the wall dry, then decide what internal work is actually needed. It is slower and it is cheaper.
What opening up the walls triggers under Building Regulations
Renovation work pulls in requirements that a cosmetic refresh does not, and the thresholds are specific.
Under Approved Document L, renovating a thermal element brings an obligation to upgrade it once the work covers more than half the surface of that individual element, or more than a quarter of the total building envelope. Dry lining most of an external wall counts. So does stripping a roof. The improved standards are 0.16 W/m²K for roofs, 0.55 for a wall suitable for cavity insulation, 0.30 for a wall taking internal or external insulation, and 0.25 for floors. There is relief where the upgrade is not technically feasible or would not pay back within fifteen years, but you still have to reach the best value that is practicable, and generally no worse than 0.70.
Electrical work falls under Part P. Installing a new circuit, replacing the consumer unit, or altering existing circuits in a special location such as a bathroom is notifiable, and must be certified either by a registered competent person or through building control. Given how many Chatham terraces still carry a century of accumulated modifications, most full renovations here end up as a complete rewire rather than a partial one.
Ventilation matters as soon as you start sealing a draughty old house. Improving airtightness without matching it with extract and background ventilation trades draughts for condensation, and Approved Document L points directly at Part F for that reason.
Assume asbestos before 2000
The HSE position is that if a building was built or refurbished before the year 2000, you should assume asbestos is present. In a Chatham terrace that has been improved repeatedly since the 1950s, the likely candidates are textured coatings such as Artex, vinyl floor tiles and their bitumen adhesive, insulating board around boilers and behind fire surrounds, and cement products in outbuildings and rainwater goods.
In an owner-occupied home you are not the dutyholder in the way a commercial building owner is, but the Control of Asbestos Regulations still govern the work being done in your house. Any contractor who proposes to start ripping out ceilings in a pre-2000 property without raising this at quotation stage is telling you something about how they run sites.
Party walls matter more in a terrace
Chatham’s terraced streets mean most renovations touch a party wall on one side or both. Removing a chimney breast, cutting in beams, underpinning or taking down a wall between two rooms can all bring the Party Wall etc. Act 1996 into play, and the notice periods are not short. Party structure notices need two months, line of junction and excavation notices need one month.
Homeowners frequently discover this two weeks before they hoped to start. Serving notice early costs nothing and protects you if a neighbour later claims damage. This is the sort of thing that belongs in the planning stage of the project rather than the middle of it, and it sits alongside the other essential steps in a house renovation project that determine whether a programme holds.
Living in the house while the work happens
Most Chatham renovations happen around people. That changes how a site should be run.
Warren boxes in and protects the interior before any breaking out begins, and the team clears up at the end of each day rather than at the end of the job. He manages the programme and sequences the trades himself, which is the part that keeps an occupied renovation tolerable, because it is the gaps between trades, not the trades themselves, that stretch a six week job into twelve. Over thirty years in the industry that has been the consistent difference between a build that runs and one that drifts.
If the renovation includes adding space as well as improving what is there, the same principles apply to extension work across Medway, and structural alterations sit within our wider construction work. You can see completed projects across Chatham, Rochester and the surrounding towns in our portfolio, and our aftercare covers the things that only reveal themselves once you have lived through a full winter in the finished house.
