Renovations in Sidcup

Bringing interwar houses up to date

Most of Sidcup was built between the wars, and a lot of those houses are now on their second or third owner with original wiring, tired heating, a small closed-off kitchen and a bathroom from another decade. A proper renovation deals with all of it at once: rewire, new heating, replastering, a kitchen that works for how people live now, and a bathroom that adds value rather than costs it.

We're based in Sidcup and our renovations service covers all of DA14 and DA15. Most renovations don't need planning permission, but structural work, rewires and moved bathrooms do need building control, and we handle that from start to sign-off.

Sidcup Property Types

What we usually find

Blackfen, Lamorbey & Albany Park

1930s semis

Original lath-and-plaster ceilings, ageing wiring, suspended timber floors and a small kitchen separated from the dining room. A full renovation usually means rewiring, replastering and opening the kitchen into the back room.

Station & Halfway Street

Edwardian houses

High ceilings, original features worth keeping and services that have been patched for decades. We renovate around cornices, fireplaces and joinery rather than ripping them out.

The Hollies & Longlands

Cottage-style interwar

Smaller rooms and conservation area status. Internal work rarely needs planning, but replacement windows and external changes do. We check before anything is ordered.

Lamorbey & The Green

Larger detached and semis

Bigger houses where a full renovation often runs alongside an extension or loft conversion. We programme them as one job.

Sidcup flats

Purpose-built and converted

Flat refurbishments for owners and landlords, often between tenancies, with leaseholder and freeholder consents handled up front.

Post-war Housing

Foots Cray and New Eltham border

Solid walls, older heating systems and dated layouts that respond well to a full strip-out and refit.

Before You Start

What to know before renovating in Sidcup

Most internal renovation work doesn't need planning permission, but some of it needs building control, and Sidcup's conservation areas affect anything you change on the outside.

Building control

Rewires, new circuits, steels, moved bathrooms, new windows and boiler changes all need building regulations sign-off. We notify Bexley building control and manage inspections.

Conservation areas

Sidcup has eight. Internal work is unaffected, but replacement windows, doors and external finishes in these areas may need planning permission.

Article 4

Old Forge Way carries an Article 4 direction. Changes to windows and doors facing the street there need a full application.

Party walls

Cutting into a shared wall to insert a steel usually triggers the Party Wall Act on a semi. We flag it early so notices go out in time.

Asbestos

Houses of this age can contain asbestos in textured ceilings, floor tiles and boiler cupboards. We test before strip-out where there's any doubt.

Living in during works

We agree up front which rooms stay usable and how dust is sealed off, so you know what each week of the job looks like.

Conservation Areas

Sidcup's conservation areas

Internal work isn't affected, but external changes in these areas may need permission:

Christ Church The Green Halfway Street The Hollies Longlands Road Old Forge Way The Oval Willersley Avenue & Braundton Avenue

We check your address before any windows, doors or external finishes are ordered.

How It Works

Our renovation process in Sidcup

Step 1

Free consultation and site visit

We walk the property with you, room by room, and talk through what you want to achieve. We flag anything that needs structural input or building control before it becomes a surprise.

Step 2

Detailed quote and scope of works

You get a fully itemised quote and a written scope covering every room, every trade and every finish. Nothing is left as a vague allowance.

Step 3

Pre-start planning

We sequence the trades, order long-lead items like kitchens and sanitaryware, notify Bexley Council building control where needed, and agree how the house will be protected while you live in it.

Step 4

Strip-out and first fix

Old finishes come out, then electrics, plumbing, heating and any structural work go in while walls and floors are open. This is where most hidden problems are found and fixed properly.

Step 5

Second fix and finishes

Plastering, kitchens, bathrooms, flooring, joinery and decoration run as one programme with no gaps between trades.

Step 6

Snagging and handover

We walk the finished house with you, fix anything that isn't right, and hand over certificates for electrics, gas and building control. We don't close the job until you're satisfied.

Common Questions

Sidcup renovation FAQs

How much does a house renovation cost in Sidcup?

+

It depends on the size of the house and the specification. A cosmetic refurbishment of a two-bedroom flat might start from £20,000 to £35,000. A full renovation of a three-bedroom semi, with new kitchen, bathroom, rewire, replastering, heating and decoration, typically ranges from £60,000 to £120,000. We'll give you an accurate figure after visiting.

Can I stay in my home during the renovation?

+

For a kitchen or bathroom, yes, most clients stay throughout. For a full house renovation it depends on how many rooms are stripped at once. Moving out for the heaviest weeks usually makes the job faster and cheaper, and we'll tell you honestly at the consultation which applies.

Do I need building regulations approval?

+

Cosmetic work like decorating, flooring and like-for-like replacements doesn't. Removing load-bearing walls, new steels, rewiring, new circuits, moving bathrooms and replacing windows do. We handle building control notifications and sign-off as part of the job.

How long does a full renovation take?

+

A kitchen or bathroom takes 2 to 4 weeks. A full flat refurbishment takes 4 to 10 weeks. A full house renovation takes anywhere from 8 weeks to 6 months depending on scope. You get a written programme before we start.

Do you work with landlords and investors?

+

Yes. We regularly refurbish properties between tenancies and before sale, working to fixed deadlines with keys handed back on the agreed date.

Do you supply materials or do I buy them?

+

Either. Most clients let us supply everything at trade price, and choose finishes like tiles, taps and kitchen fronts themselves from a set of options. If you'd rather buy some items yourself, we build that into the programme.
