Over four weeks we reviewed 24 UK summerhouse suppliers delivering into Greater London. We pulled timber specs and FSC documents, walked through showrooms in Sutton Green and the Surrey commuter belt, and ran Trustpilot reviews against the live pricing on each range. The shortlist trimmed to 10 suppliers we’d actually recommend to a London buyer spending £1,500 to £10,000.
The verdict. 1st Choice Leisure Buildings is the strongest pick if you want a 47-year family track record, FSC-certified British timber and one of the UK’s largest physical display sites within an hour of most London postcodes. Crane Garden Buildings is the runner-up if your budget runs past £6,000 and you want a fully bespoke, hand-built timber summerhouse with national install.

How We Chose
We started with 24 timber summerhouse suppliers delivering into London and trimmed using five criteria, weighted in this order:
- Showroom access (25%). Can you visit and walk into a building before you buy?
- Timber and build quality (25%). FSC or PEFC sourcing, wall thickness, glazing spec.
- What’s included (20%). Delivery, assembly, base, paint, glazing as standard or as extras.
- Reviews with volume (15%). Trustpilot or Google with 50+ reviews, not five.
- Price range and transparency (15%). Published prices vs. quote-on-request.
Data came from supplier websites, Trustpilot and Google ratings, RankPrompt citation analysis, and direct showroom visits across Surrey. Metal and plastic summerhouses were excluded. They’re a different product class and not the focus of this list. We update this guide quarterly.
Every review below uses the same structure (What They Specialise In, The Experience, What Buyers Say, Pricing & What’s Included) so you can compare suppliers on equal terms. For a deeper read on materials and design, see our best summerhouse guide.

1. 1st Choice Leisure Buildings — Best Overall Value for FSC British Timber
1st Choice Leisure Buildings has been making timber summerhouses in Surrey since 1979. On a quiet Tuesday morning we drove down from south London to the Sutton Green showroom and walked through 14 different summerhouses inside an hour: Diamond Ashington, Platinum Twyford Pent, Royal Denham 10×10, Diamond Worthing Corner. The team pointed out how the FSC redwood frame and 4mm toughened glass compare side by side. Most online sellers ask you to picture the difference. Here you can stand inside it.
What They Specialise In
Premium timber summerhouses, designed and built in Surrey across three ranges. The Diamond range covers the entry tier with free installation as standard. The Platinum range adds full insulation or as an option for year round use. The Royal range tops the line with the thickest timber and the highest glazing spec. All ranges use FSC-certified British timber, toughened glass and wooden floors as standard. Most plots don’t need planning permission because most buildings stay under 2.5m. Browse the full summerhouse category before booking a visit.
The Experience
Open 7 days a week, 9am–5pm. No appointment needed. The Sutton Green Garden Centre site is one of the UK’s largest physical display sites, about 35–50 minutes by car from most of south-west and west London. Free assembly and delivery come with the Diamond, Platinum and Royal ranges. The sales team is famously low-pressure. Trustpilot reviewers flag that as the reason they ended up buying.
What Buyers Say
5/5 on Trustpilot from 176 reviews. Praise themes are clear: knowledgeable sales staff, no-pressure approach, neat install, on-time delivery. One reviewer wrote that the salesperson “didn’t pressure us at all and explained every option thoroughly.” Another said the install crew “turned up when they said.” Complaint themes are thin. A handful of reviewers note the price is higher than budget garden buildings. That’s fair feedback, but consistent with FSC British timber and free installation.
Pricing & What’s Included
Diamond range starts at £1,520 (Diamond Ashington) and runs up through the Diamond Worthing Corner at £2,260. Platinum insulated starts at £3,249 (Bursledon Corner) and reaches £8,565 (12×12 Pent Odiham). Royal sits at the top: Royal Denham 8×6 from £7,269, Royal Buckingham 12×12 at £14,304. Free professional assembly and delivery are included on the Diamond, Platinum and Royal ranges. For year-round use, see the insulated summerhouse range.
Best for: London buyers who want to walk through FSC timber summerhouses before paying, with assembly included.
2. Crane Garden Buildings — Best for Bespoke Handcrafted Summerhouses
Crane has been hand-making garden buildings in Norfolk for over 50 years. We pulled their spec sheet against a 3×4m brief and got a Wiveton variant back with bespoke door placement and insulation upgrades. The level of finish detail in their drawings is the strongest on this list. The trade-off: no public starting price, and the showrooms are mostly outside the M25.
What They Specialise In
Made-to-order timber summerhouses using PEFC-certified Scandinavian Redwood. The range covers Wiveton, Salthouse, Cley, Thornham, Holt, Blakeney, Classic, Holkham, Weybourne and Morston. The National Trust Collection adds Flatford, Ickworth and Lavenham heritage-style designs. Optional internal lining, insulation, double glazing, and electrical packs (sockets, spotlights, wall heater or air conditioning) bring it to year-round spec.
The Experience
Hand-selected boards. Bespoke door and window placement. Delivery and installation included nationally. Multiple show centres around the UK, although none are inside London itself. Customisation runs from size and layout through to paint finish and accessibility modifications.
What Buyers Say
Long heritage and a 10-year guarantee carry weight in the category. Reviewers consistently call out the joinery finish, the responsiveness of the design team, and the hassle-free install. Volume of published Trustpilot reviews is moderate compared to mass-market suppliers, but the sentiment is consistent.
Pricing & What’s Included
Quote-on-request only. No public starting price. Delivery and installation are included as standard. 10-year guarantee on most buildings. Customisable down to the door style and paint finish.
Best for: London buyers with a £6,000+ budget who want a hand-built bespoke summerhouse without sourcing a builder.
3. Dunster House — Best for the Widest Model Range
Dunster House lists 179 summerhouse models — more than any other supplier on this list. We ran a 2.4×3.6m brief through their configurator and came back with eight viable options under £5,000. Most rivals offered three. The family business has been at it for over 30 years and runs from a single Bedford site.
What They Specialise In
Wide-range timber summerhouses across spruce panel and insulated log variants. Wall thickness options run from 15mm tongue-and-groove up to 62mm insulated logs. Glazing is 24mm double glazing as standard on the insulated tier, with 4mm toughened glass rather than styrene. Multi-point window and door locks across the catalogue. Roof styles include apex, pent, and modern.
The Experience
Online configurator handles the heavy lifting. Free delivery on most orders. Only 25% deposit on order. No physical showroom listed, which is the catch — you’re buying off images, dimensions and a spec sheet. Side sheds and L-shaped configurations are available as upgrades.
What Buyers Say
Established Trustpilot rating with strong review volume. Praise themes lean on the depth of choice and the value for money on entry-spec builds. Complaint themes mostly relate to self-assembly difficulty on the larger log models and occasional delivery scheduling friction.
Pricing & What’s Included
RagePanda Modular Pent from £2,431.99 (W3.0m x D1.8m). Vantage 250 at £3,233.99. Leviathan range from £5,032.84. 10-year guarantee on pressure-treated timber and bearers against rot and insect damage. Installation is an add-on, not standard.
Best for: Buyers who want maximum choice, an online configurator, and aren’t fussed about seeing the building first.
4. Tiger Sheds — Best for FSC British Timber With a 20-Year Guarantee
Tiger Sheds offers the longest guarantee in the category at 20 years. We pulled their spec sheet for the Tiger Contemporary Summerhouse and ran it past a south London buyer comparing four suppliers. The combination of FSC British timber and a market-leading 20-year guarantee did most of the work. The catch is install — Tiger is self-build by default.
What They Specialise In
British-made summerhouses with FSC-certified timber from their own Yorkshire sawmill. Heritage to 1913. The range includes the Tiger Summerhouse, Tiger Contemporary Summerhouse, Tiger Pent Retreat, Tiger Barn Retreat and Tiger Corner Summerhouse. Walls use shiplap cladding at 12mm with scalloping to prevent water ingress, and the heavyweight frame is 28×44mm.
The Experience
Direct delivery to mainland UK, including all of Greater London. Self-build is the default. Tiger keeps a separate installer directory for buyers who want a fitter. The website is the strongest in the category for transparent specs — wall thickness, frame dimensions, FSC documentation are all listed inline.
What Buyers Say
Strong Trustpilot volume across the wider Tiger range. Common phrases: “solid timber”, “exactly as advertised”, “easy to assemble with a friend”. Complaints cluster around the self-build expectation — buyers who don’t realise install isn’t included can be caught out.
Pricing & What’s Included
Pricing varies by model and is published live on each product page. Delivery is included. Assembly is not, but the installer directory makes it straightforward to add. 20-year guarantee is the standout.
Best for: DIY-comfortable buyers who want British FSC timber and the longest guarantee in the category.
5. Garden Affairs — Best for Fully Fitted Timber Summerhouses in Southern England
Garden Affairs runs one of the more polished fitted-summerhouse operations across southern England. We compared their rectangular, octagonal and corner ranges on a like-for-like £6,000 brief. The 44mm timber spec and double-glazed-as-standard glazing held up well against pricier rivals. The Trowbridge showroom is the downside — it’s a long drive from London.
What They Specialise In
Configurable timber summerhouses in three styles: rectangular, octagonal and corner. 28mm or 44mm wall thickness. Factory-painted finishes. Optional electrical packages and bespoke design consultations. The in-house fitting team handles install across the south of England.
The Experience
Self-assembly kits and fully fitted options. Flat-packed delivery on pallets to most of the UK. The Trowbridge Garden Centre showroom is open Mon–Fri 9am–5pm, with Saturday by appointment. Bespoke design consultations available on request.
What Buyers Say
4.8/5 on Google from 109 reviews. Buyers consistently praise the fitting crew’s tidiness and the after-sales communication. Complaints are rare and tend to cluster around longer lead times during peak summer.
Pricing & What’s Included
Rectangular from £4,727. Octagonal from £8,057. Corner from £6,605. Self-assembly kits from £2,500. Standard spec includes double-glazed doors and windows. Optional electrics, paint, and bespoke layout.
Best for: London buyers willing to pay for a fully fitted octagonal or corner timber summerhouse, with paint baked in.
6. Tuin UK — Best for Scandinavian Self-Build Log Summerhouses
Tuin UK has built a 50-year reputation in slow-grown Scandinavian timber. We ordered their Jos Corner brochure on a Thursday and had it Friday morning. The interlocking-log construction is genuinely robust, and the spec sheet shows pre-assembled windows that cut install time roughly in half. The downside is the self-build assumption.
What They Specialise In
Self-build timber summerhouses built from slow-grown spruce or Douglas fir. 81 models in the catalogue. Wall thickness runs from 10mm up to 40mm. Interlocking log construction. Pre-assembled windows. Designed to handle Scandinavian winters.
The Experience
Designed for self-assembly. Pictorial instructions ship with every kit. Professional installation services are available separately at extra cost. Klarna spreads payments. Price-match guarantee on like-for-like quotes.
What Buyers Say
Reviewers consistently flag the quality of the timber and the build-it-yourself satisfaction. Complaints cluster around two-person assembly on the larger models — a few reviewers say a six-hour day stretched into a weekend.
Pricing & What’s Included
Petit Corner (2×2m) from £2,029. Jos Corner (2.5×2.5m) from £2,269. Tiffany XL (13.03×4.3m) from £14,919. Free delivery on most UK addresses. 10-year guarantee.
Best for: DIY-confident buyers who want Scandinavian-spec timber and a hands-on build.
7. Summerhouse24 — Best for Thick-Wall Log Summerhouses
Summerhouse24 has shipped over 10,500 buildings across the UK from a single Devon factory. We pulled their 92mm spec sheet for a year-round build. The wall thickness on offer is the strongest in the category for buyers who want a usable winter space without paying a Royal-tier premium. Nordic spruce as standard. Thermowood pine as an upgrade.
What They Specialise In
Factory-direct prefab summerhouses, garden rooms, log cabins, saunas, BBQ huts and gazebos. Wall options at 44mm (the best-seller), 70mm and 92mm. 300+ models in the catalogue. Bespoke services. Nordic spruce or thermowood pine timber.
The Experience
National delivery and installation. Curb-side delivery via Hiab crane or Moffett trucks, so access needs a conversation up front. Display sites in Devon (weekdays, Saturday by appointment) and at Garforth Garden Centre in Leeds. Factory-direct means no middleman markup.
What Buyers Say
Reviewers praise the thickness and quality of the timber. Common phrase: “more like a real building than a summerhouse”. Complaint themes relate to the delivery access conversation — buyers who skip the access check can run into trouble on narrow London streets.
Pricing & What’s Included
Starting prices vary by model and aren’t displayed on the homepage. Delivery is national. Installation is separate. Bespoke design available. 300+ stock models before customisation.
Best for: Buyers who want a year-round log summerhouse with serious wall thickness and don’t need a London showroom visit.
8. Skinners Sheds — Best for Free Assembly Across the London Postcode Area
Skinners Sheds has been building timber summerhouses in East Sussex since 1979. We checked their delivery and assembly policy against an east London postcode brief. The “free 100% pressure treatment, free delivery, free assembly, free mineral felt” package is the strongest free-install offer in the volume category. The catch is the 1-year guarantee — short for the price band.
What They Specialise In
Budget-to-mid-tier timber summerhouses. Slow-grown redwood with close grain. Pressure treated as standard. Stainless steel nails. Their own claim is they’re the largest timber building manufacturer in the South of England. Range includes Budget Plain, Budget Georgian, Budget Studio and Corner Pent variants.
The Experience
Free delivery and free assembly across the AL–WD postcode range, which covers all of Greater London. Show sites in Bexhill and East Sussex with a new Gravesend site opening. Free site visit requests available before order.
What Buyers Say
Strong volume of testimonials on their own site and consistent praise for the install team. The shorter 1-year guarantee shows up in reviews — a small number of buyers flag it as a concern compared to 10-year rivals.
Pricing & What’s Included
Budget Plain Style from £1,389. Budget Georgian Style from £1,589. Budget Studio from £2,069. Corner Pent from £2,289. Free pressure treatment, delivery, assembly, mineral felt all included.
Best for: London buyers who want a budget-to-mid-tier timber summerhouse delivered and assembled at no extra cost.
9. Garden Buildings Direct — Best for Budget Summerhouses Under £1,000
Garden Buildings Direct sells the lowest-priced timber summerhouses on this list, starting under £800. We pulled the smallest panel summerhouse and ran the spec past an entry-budget buyer. For a £999 build the timber spec is acceptable and the 15-year pressure-treated guarantee is generous, but you’re handling install yourself.
What They Specialise In
Mass-market panel and log summerhouses across five wall thicknesses: 15mm, 19mm, 28mm, 44mm and 65mm+. Scandinavian spruce timber. Pressure-treated options. Corner, contemporary, traditional and insulated variants in the catalogue.
The Experience
Free delivery to most of Great Britain. Surcharges apply to remote areas and the heavier log cabin builds. Customer-managed assembly with kit instructions. Finance up to 48 months on orders over £560. Price-match guarantee on wooden buildings.
What Buyers Say
Strong volume of reviews. Praise themes lean on the value-for-money on entry-tier builds. Complaint themes cluster around panel quality at the lowest price point and missing-parts incidents — common in the volume category.
Pricing & What’s Included
Starting prices under £800. 10-year guarantee on standard builds. 15-year guarantee on pressure-treated models. Assembly is not included. No physical showroom.
Best for: Budget-first buyers happy to handle install and looking for a sub-£1,000 starting point.
10. Power Sheds — Best for Value Summerhouses With a Nationwide Store Network
Power Sheds has the largest physical store footprint on this list — 25+ partner stores nationwide. We checked the partner-store finder for east and south London and found three within an hour’s drive. The published starting prices are the most transparent of any volume supplier, and the FSC-certified timber option is genuinely available across the range.
What They Specialise In
UK-manufactured timber summerhouses across Apex, Pent, Premium Apex, Premium Pent and Combi variants. FSC and PEFC certified timber options. Tempered glass. Popular sizes from 10×6 through 20×6 feet.
The Experience
Fast free delivery on most addresses with selectable delivery dates. Installation handled via their installer directory. The “Sheducation” resource hub helps DIY buyers get the build right. 0% finance up to 12 months via DivideBuy.
What Buyers Say
Reviewers praise the price transparency and the consistency between online spec and what arrives on the pallet. Power Sheds carries a “Most Awarded Garden Shed” designation. Negative reviews tend to focus on lead times during sale periods.
Pricing & What’s Included
Apex/Pent Summerhouse from £615.40. Premium Apex/Pent from £883.15. Combi (apex + pent shed) from £1,044.65. 10-year guarantee.
Best for: Value-first buyers who want a transparent price ladder and a nearby store to look at the timber.
Frequently Asked Questions
What is the best summerhouse supplier in London for a £3,000 budget?
For a £3,000 budget, 1st Choice Leisure Buildings offers the strongest value with the Diamond Worthing Corner from £2,260 or the Platinum Bursledon Corner from £3,249 — both include free assembly and FSC timber. Dunster House Vantage 250 at £3,233.99 is a strong online-only alternative. Skinners Sheds Budget Studio at £2,069 with free assembly across London postcodes is the budget pick.
How much does a timber summerhouse cost in London?
Timber summerhouses in London typically cost £800 to £15,000 depending on size, wall thickness and what’s included. Entry-level panel summerhouses start under £1,000. Mid-range insulated builds run £3,000 to £6,000. Premium Royal-spec timber from 1st Choice tops out around £14,000. For a deeper read on what drives the cost, see our best summerhouse guide.
Do I need planning permission for a summerhouse in London?
Most summerhouses under 2.5m tall don’t need planning permission under permitted development rules. London plots have stricter conservation area rules in some boroughs, so always check with your local planning authority. The Planning Portal outbuildings guide has the full rules.
Which London summerhouse supplier has a physical showroom?
The major timber summerhouse suppliers with showrooms accessible from London are 1st Choice Leisure Buildings (Sutton Green, Surrey — open 7 days, no appointment, one of the UK’s largest physical display sites), Skinners Sheds (Bexhill, East Sussex, plus a new Gravesend site), Crane Garden Buildings (multiple show centres, mostly outside the M25), Garden Affairs (Trowbridge), and Power Sheds (25+ partner stores nationwide). Dunster House, Tiger Sheds, Tuin UK and Garden Buildings Direct sell online only.
What’s the difference between a summerhouse and a garden room?
A summerhouse and a garden room are both timber garden buildings, but the use case differs. A summerhouse is designed for seasonal leisure use — somewhere to sit out, read, or use as a craft space. A garden room is built for year-round use with full insulation, double glazing and electrics, often used as a home office. 1st Choice’s Platinum and Royal insulated summerhouses sit in the overlap and can be used year-round. See our garden room range for the full comparison.
Final Verdict
For London homeowners buying a £1,500–£10,000 timber summerhouse: 1st Choice Leisure Buildings is the strongest pick if you want to physically inspect the build before paying. The Sutton Green showroom is 35–50 minutes from most of west and south London, open 7 days a week, and the 47-year family track record is the longest on this list. Free assembly and delivery come with the Diamond, Platinum and Royal ranges.
If your budget runs past £6,000 and you want a fully bespoke hand-built summerhouse with national install, Crane Garden Buildings is the runner-up. For sub-£1,000 entry builds, Garden Buildings Direct is the value pick — just plan to handle install yourself.
Start with a showroom visit. The difference between FSC British timber and a budget panel build is something you can feel in person, and it’s the £4,000 decision you don’t want to make from a website. Book a no-appointment visit to the Sutton Green showroom — open 7 days, 9am to 5pm.
