Same-week slots · Fully insured · Local Mottingham fitters · Fixed written pricesLooking for shed assembly in Mottingham SE9? We work in Mottingham most weeks — a quiet interwar suburb between Eltham and Chislehurst — and price shed assembly against that reality rather than a London average. Fixed written quote from £140, insured fitters, the frame squared before roofing and anchors fitted where needed.
Overview
This page prices shed assembly for Mottingham SE9 specifically: inter-war stock, 17% privately rented and 3,789 households in total. Work starts at £140, fixed in writing, with parking and London Borough of Bromley permit rules costed before an insured fitter travels.
How it works
Step 1
Base checked for level and size, and the shed's height and position checked against the garden's remaining permitted development allowance.
Step 2
Panels, roof struts and fixings checked against the parts list — a shed with a bent panel or a short bag of screws is found before the frame goes up, not halfway through.
Step 3
Floor and wall panels built up and squared before the roof goes on, since an out-of-square frame is what makes doors stick.
Step 4
Roof panels fitted, felt or shingle lapped correctly and any window or vent sealed.
Step 5
Ground anchors or wall straps fitted in exposed gardens, doors hung and eased, packaging taken away.
Why choose us
Fitters carry £5m public liability cover. Most garden sheds fall under permitted development if they sit under 2.5m at the eaves within 2m of a boundary and the total of all outbuildings stays under 50% of the garden — we flag it if a build looks close to either limit rather than assume it is fine.
One fitter for a small shed on a ready base; two for anything over 8x6ft or where roof panels need lifting together. Wide roads and driveways throughout, with easy turning for a Luton.
Most builds are booked within a week, longer in spring when garden project demand peaks across London. Mottingham (Southeastern) is the nearest station, so a SE9 visit rarely needs a whole morning set aside.
We expect precast concrete panels and dense blockwork; locally that also means often with surface conduit, and with 30% one-person households in Mottingham, one adult is usually the only pair of hands on site in SE9, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is Mottingham gives us drilling blind into a panel with reinforcement or a buried cable behind it, which is what a 25% flat share across the ONS neighbourhood covering Mottingham actually produces.
Fixed prices
| Job | From | Typical time | What sets the price |
|---|---|---|---|
| Small shed up to 6x4ft, base ready | £140 | 2–3 hrs | A one-piece or simple panel shed on an existing slab, framed, roofed and felted in a morning. |
| Medium shed 8x6ft, base ready | £220 | 3–5 hrs | More panels and a ridged roof mean more bracing before the structure is rigid enough to felt. |
| Large shed or workshop 10x8ft+, base ready | £320 | 5–7 hrs | Heavier framing, often double doors and a window, and usually a two-person lift for the roof panels. |
| Paving-slab base, per m² | £45 | By area | Compacted hardcore and a sand bed under the slabs, laid to a slight fall so water runs away from the shed floor. |
| Timber bearer base on an existing hard surface | £85 | 2–3 hrs | Pressure-treated bearers levelled and packed to keep the shed floor off standing water without a full slab. |
| Anchor kit for an exposed or elevated garden | £60 | 45–60 min | Ground anchors or wall straps fitted so the shed does not lift in a gust funnelled between two terraces. |

Scope
Sulltan is the best handyman in London. He is very reliable and professional. I highly recommend.
Really pleased with our house move. The guys came on time, loaded everything carefully like a huge jigsaw! Nothing got broken and even though they were working on an hourly rate they were really efficient, not to waste any time. Our only criticism is that we needed a few items disassembled to get on the… Read in full →

Working in Mottingham
Mottingham SE9 is inter-war and social-housing-led: 25% of homes here are flats and 75% are houses, across 3,789 households (ONS Census 2021).
The social-housing-led mix here (50% owned, 17% privately rented) means a SE9 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Expect precast concrete panels and dense blockwork; locally that also means often with surface conduit, and with 30% one-person households in Mottingham, one adult is usually the only pair of hands on site behind the plaster in SE9. That is why fixings are picked in the room rather than off a van shelf, and why Mottingham gives us drilling blind into a panel with reinforcement or a buried cable behind it, which is what a 25% flat share across the ONS neighbourhood covering Mottingham actually produces is the fault we are called back to undo.
A quiet interwar suburb between Eltham and Chislehurst. That character decides the practical detail of shed assembly here far more than the borough boundary does. Mottingham is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
On access, wide roads and driveways throughout, with easy turning for a Luton — one reason one fitter for a small shed on a ready base; two for anything over 8x6ft or where roof panels need lifting together. Fitters travelling in use Mottingham (Southeastern).

Small shed up to 6x4ft, base ready starts at £140 in Mottingham across SE9, with Bromley parking rules in play — and 75% of Mottingham homes being houses, and every job is quoted as a fixed written price before a fitter is booked. Shed size and whether the base already exists. A slab or bearer base adds a separate charge but saves the shed floor from sitting on wet grass or bare soil through its first winter on SE9 jobs — and 30% one-person households here, with this being London Borough of Bromley territory.
5m at the eaves within 2m of a boundary and all outbuildings together stay under half the garden on the streets near Mottingham Village and Fairmount recreation ground, with 75% of Mottingham homes being houses. Many gardens in Mottingham are small enough that a large shed pushes close to that limit — we check before booking rather than after the kit is built for Mottingham (SE9) addresses — and a median age of 37 in this neighbourhood, with 33% social-rented stock nearby.
Yes — a paving-slab base is £45/m², with 17% of SE9 homes being privately rented, or a timber bearer base from £85 where a full slab isn't needed across SE9. With 75% of Mottingham homes being houses with a garden, most jobs here are base-plus-build in one visit on the Mottingham rounds, with this being a short walk from Mottingham (Southeastern).
Not once anchored. Terraced gardens funnel wind between the houses more than an open plot does, with a median age of 37 in this neighbourhood, so we fit ground anchors or wall straps as standard rather than leave it to the kit's own fixings for Mottingham (SE9) addresses — and 17% of SE9 homes being privately rented, which is Mottingham gives us drilling blind into a panel with reinforcement or a buried cable behind it, which is what a 25% flat share across the ONS neighbourhood covering Mottingham actually produces on unanchored builds we're called back to.
Laying a full concrete slab base — quoted separately as a groundworks job; Electrical supply to the shed on Bromley bookings — and 25% of homes here being flats, with 75% of Mottingham homes being houses, which needs a registered electrician for the armoured cable and consumer unit work; Party wall or boundary consent where a shed sits within 2m of a neighbour's fence and exceeds the height limit. Anything outside that scope is quoted separately so the Mottingham SE9 price you agree is the price you pay on the Mottingham rounds, with Mottingham Village and Fairmount recreation ground a few streets away.
All three. With 17% of Mottingham privately rented and 50% owner-occupied, roughly half the SE9 diary is agent- or landlord-instructed and invoiced separately from the person at the door around Mottingham (Southeastern) — and Mottingham Village and Fairmount recreation ground a few streets away, with 3,789 households on this patch.
Mottingham Village and Fairmount recreation ground is the marker we route to, with 33% social-rented stock nearby, and wide roads and driveways throughout on the streets near Mottingham Village and Fairmount recreation ground, with easy turning for a Luton. A SE9 slot added to an existing Bromley round usually lands the same week rather than the next across SE9, with 30% one-person households here.
