Working with architects and building surveyors
London and Kent Construction is a main contractor for residential renovation and refurbishment across South East, South West and West London. We price from your drawings and specification element by element, with exclusions set out as clearly as inclusions, then build to the design under a JCT contract suited to the job. Quantity surveying is done in house.
What kind of projects does London and Kent take on?
London and Kent Construction works on Victorian, Edwardian and Georgian houses and flats, including listed buildings and homes in conservation areas. The work runs from whole property renovation and refurbishment to extensions, loft conversions, structural alterations and basements. Most whole property renovations we carry out cost £150,000 to £500,000, and some cost more. Single rooms are usually around £10,000 to £15,000.
Our projects are in South East London (Greenwich, Blackheath, Eltham, Charlton and Lewisham) and in South West and West London (Battersea, Clapham, Wandsworth, Kensington, Chelsea, Notting Hill, Hammersmith and Fulham). The business was established in 1995, incorporated in 2003 and is part of The New Greenwich Group.
How does London and Kent price a tender?
Every London and Kent quotation is priced element by element from a measured scope, so it can be read line by line, compared with the other tenders and value engineered without redesigning the job. Exclusions are set out as clearly as inclusions, and provisional sums are marked as provisional.
Where a package is incomplete, we say what is missing and what we have assumed, in writing, rather than pricing around the gap and leaving you to find it at final account. That matters for the reason one London practice gives in its guidance to clients: "The single biggest protection against cost surprises is tendering from a complete package. If builders price from incomplete drawings, their quotes are not comparable and the cheapest number often hides the most assumptions" (Hampstead Architecture, June 2026).
What happens to the price after appointment?
London and Kent does not revisit the number after appointment. Anything outside the agreed scope is priced in writing and instructed before the work is done. Variations are valued as they arise, on monthly valuations, rather than collected up and presented at final account. Your client sees the cost of a change while there is still time to decide, and you are not left defending a final account you have not seen coming.
Who runs the job on site?
London and Kent works with one directly employed team, supported by specialist trades. One contracts manager, employed by the company, runs the job from the first survey to handover. Valuations and variations are handled by Dotun, our in house quantity surveyor, who knows the job, rather than by a surveyor bought in for each project.
Every job has a WhatsApp group, so the design team has an open line to the people on site alongside calls and emails. We work to whatever meeting rhythm the practice prefers. A defects period of normally twelve months follows handover.
Which contract and guarantee does London and Kent use?
We work under a JCT contract suited to the job: the Home Owner contracts, Minor Works or a form for larger works. Where you are administering the contract for a homeowner, JCT publishes a version for exactly that arrangement: "This contract is for a home owner/occupier who has appointed a consultant to administer the contract on their behalf" (JCT, Building Contract and Consultancy Agreement for a Home Owner/Occupier). For projects with a fuller set of trades, JCT describes its Intermediate contract as "designed for construction projects involving all the recognised trades and skills of the industry, where fairly detailed contract provisions are needed" (JCT).
We offer an insurance backed guarantee. London and Kent Construction Ltd is company number 04853030 on the Companies House register, and we are members of CHAS and Constructionline and registered with NHBC.
Do you work to a building surveyor's schedule?
Yes. Remedial schedules, condition led work and communal repairs on blocks are priced line by line against the schedule as issued. Anything we think is missing or wrongly described is raised in writing before we price it, not claimed for afterwards. Our own work includes the refurbishment of a Chelsea mansion block: brickwork, pointing, roof works and the communal areas.
Does London and Kent design as well as build?
No. We do not have an in house design team. When a homeowner comes to us direct and the work needs designing, we bring in external architects and designers. On projects you introduce, the design stays with you: our job is to price it properly and build it as drawn.
What does a project with an architect look like?
One recent example is a four bedroom period house in Chiswick, where we worked alongside an architect. The kitchen, drawing room and dining room were rearranged and remodelled, with walls taken down to open up the ground floor and ceilings raised. The work was finished within the agreed budget.
We work regularly with one architecture practice in particular, Vertex Architecture.
We also take on jobs that another builder has left unfinished, including two in Notting Hill. If a project you are running has stalled, see taking over a stalled site. The initial assessment is free.
Questions practices ask
Will you price from our package?
Yes. We price element by element from the drawings and specification you issue. If something is missing, we say what it is and what we have assumed, in writing, before we price it.
What size of project do you take?
Most of our whole property renovations cost £150,000 to £500,000, and some cost more. We also take on extensions, loft conversions, structural work and single rooms, which usually start at around £10,000 to £15,000.
Who will we deal with?
One contracts manager employed by London and Kent, from first survey to handover, with Dotun, our in house quantity surveyor, handling valuations and variations.
How are variations handled?
Priced in writing and instructed before the work is done, and valued as they arise on monthly valuations.
Is the first site visit free?
Yes. We walk the building with you, say what we think the real issues are and what still needs designing before it can be priced. There is no charge and no obligation.
How can we check you?
