🏬 2026-06-01 — BREAKING: Savills Reverses Forecast to -2%; Conversions Surge to 40% of Planning

🚨 BREAKING: Savills Reverses 2026 Forecast

1 JUNE 2026 Savills has revised its 2026 UK house price forecast from +2% to -2%, citing the Iran conflict, rising mortgage rates, and landlord sell-offs from the Renters' Rights Act. The greatest downward pressure is expected over summer 2026. However, the 5-year forecast remains +18.5% to 2030 (~£67k average price rise), with a V-shaped recovery expected after the short-term dip.

Implication for commercial-to-resi: Lower GDV for 2026 completions = tighter margins. Target auction/distressed purchases. Hold through the dip for 2030 recovery.

📈 Planning: 14-Year Low — But Conversions Surge to 40%

26 MAY 2026 Landmark Information Group data shows planning applications hit under 689,000 in 2025 (lowest since 2012). New build apps down 5.5% YOY. But alterations and conversions now account for 40% of all planning activity, up 4.9% vs 2024 — a structural shift toward refurbishment and change of use. Grant rates remain high at 86%.

⚠️ Reform UK HMO Article 4 — Bipartisan Risk

1 JUNE 2026 Newcastle-under-Lyme council (Reform UK majority) is investigating a borough-wide HMO Article 4 Direction. Council leader Jonathan Gullis: "I will not allow Newcastle-under-Lyme to be treated as a dumping ground." This is the first Reform UK-led council to pursue HMO A4 — signalling that Article 4 risk is becoming bipartisan. Class MA not yet affected, but the direction of travel is clear.

📊 Lettings Market (Foxtons, April 2026)

Applicant demand recovered (+9.5% MoM), supply up 3.7% YOY. 99% of renter budgets spent — affordability ceiling reached. Behavioural shift: renters more discerning; properties must earn viewings.

🏠 FTB Trends (Zoopla HPI, 28 May 2026)

FTB prices up £10k (+4.3%) to £254,750. West Midlands FTB prices up 7% — second strongest nationally. But buyer demand 10% below last year. Committed buyers still acting; discretionary movers stepping back.

🎯 Updated Tactical Recommendations

• Buy in the dip: Summer 2026 expected price trough — target commercial high street purchases Jul-Sep
• Lock conversion quotes now: Before Iran-driven material inflation feeds through
• Stress-test bridging at 1.2%/mo (up from current 1%)
• Plan for 2+ year hold — capture 18.5% recovery to 2030
• Prioritise above-shop conversions (£800-1,500/sqm, 6-9 months) as safest entry

1. Class MA Planning Fee Indexation — April 2026

From 1 April 2026, all planning fees increased by 3.8% (CPI-linked indexation). Class MA prior approval fees rise from £250 to £260 per dwelling. The Planning Portal surcharge (£91.02 inc. VAT) can be bypassed by submitting directly to the LPA.

2. Sehgal v HMRC — Landmark Mixed-Use SDLT Ruling

Tribunal awarded £1.75M refund on £18.25M mixed-use purchase (apartment + parking + storage unit). The storage unit had its own title and was "legally and functionally separate." Confirms mixed-use SDLT planning remains viable post-MDR abolition. Key takeaway: Shop + flat above = strongest mixed-use claim. Separate title/lease essential.

3. Forge House, Brierley Hill — Class MA Controversy

A 1970s office block converted under Class MA (late 2023) became a crowded HMO with alleged fire safety concerns. Dudley Council refuses to answer questions. This is a reputational risk for the entire sector — if more poor-quality conversions emerge, WM councils may introduce Article 4 directions restricting Class MA.

4. Regent House, Dudley — 34-Bed HMO Recommended

Office-to-HMO conversion recommended for approval despite West Midlands Police objections citing 1,976 violent offences, 385 vehicle crimes, and 344 ASB incidents in the ward over 12 months. Developer's personal appeal addressed police concerns.

5. Class MA Housing Supply Data

Class MA conversions accelerating: 454 (22-23) → 803 (23-24) → 1,048 (24-25) = 130% growth. But total PDR change-of-use declining as office-to-resi market matures. Class MA underutilised in WM — less competition = better deals.

6. Class MA Design Challenges

Four critical hurdles: (a) Natural light — most common refusal reason, deep floorplates problematic; (b) Sound insulation — most expensive compliance item; (c) Thermal performance — budget £50-100/m² for upgrades; (d) External amenity — roof terrace or courtyard if feasible. Best shortcut: Target buildings originally built as residential, later converted to commercial.

7. Commercial Finance 2026

Three-stage path: Commercial mortgage (4-6%) → Bridging/development finance (0.75-1.5%/mo, 65-75% LTV) → BTL remortgage (4.5-5.5% IO). Promise Money offers development finance at 75% LTV with interest "above the line" (not deducted from advance) — gives more cash at day one.

8. Best WM Target Locations

Ranked: Dudley (DY1) 8.5/10, Wolverhampton (WV1) 8/10, Brierley Hill (DY5) 7.5/10 (watch for Forge House A4 risk), West Bromwich (B70) 7.5/10, Stourbridge (DY8) 7/10, Tipton (DY4) 6.5/10, Birmingham outer 6.5/10.

9. Risk Forecast

🔴 Forge House may trigger Class MA Article 4 in Dudley within 6-12 months if more controversies emerge. Act now while rights remain unrestricted.

1. High Street Crisis — The Opportunity Context

UK high streets are in structural decline, creating the buying opportunity: 13,000 shops closed in 2024 (Centre for Retail Research), 50,000+ businesses in critical financial distress (K2 Partners 2026), and high street vacancy remaining elevated in Q1 2026 (SHW). Most pronounced in the Midlands and North. Online spending now 25%+ of total retail (vs 3% in 2006). Cancer Research UK closing 88+ charity shops by May 2026 alone. Every shuttered shop is a potential Class MA conversion. Commercial values depressed in WM town centres — entry points at below-replacement cost.

2. Class MA Deep-Dive (2026 Update)

Since the September 2020 Use Class overhaul, Class E consolidates retail, offices, cafes, gyms, light industrial etc. into one super-class. The March 2024 changes removed two major barriers (1,500 sqm cap and 3-month vacancy), but the 2-year continuous Class E use rule remains the most common eligibility failure point. Councils strictly verify: they check business rates records, council tax records, and agent photos to prove the last 2 years.

3. Article 4 Risk — WM Councils Assessed

Research across all major WM councils confirms: No WM council currently has an Article 4 removing Class MA commercial-to-resi rights. WM Article 4s exclusively target HMO conversions (C3→C4). This is a FAVOURABLE SIGNAL for Class MA in the West Midlands — but with two caveats:

• Councils KNOWN to restrict Class MA: Lambeth, Brent, Hillingdon, City of London (all London). This is a London-centric issue so far.
• Risk of spread: As Class MA applications increase in the WM (driven by 2024 rule changes), councils may respond with Article 4s to protect employment floorspace. Check annually.
• Key check for each target property: Is it in a conservation area? If so, ground-floor conversions face additional council scrutiny on 'character and appearance'.
• Birmingham: City-wide HMO Article 4 since June 2020. Class MA for C3 still available. Conservation Area Article 4s for minor alterations exist in Edgbaston, Moseley, Harborne.
• Dudley: HMO Article 4 (non-immediate, 2022). Class MA for C3 still available. No conservation area Article 4s affecting Class MA.
• Wolverhampton, Sandwell, Walsall: No Article 4s affecting Class MA. Only HMO-specific restrictions.

4. Conversion Costs — Detailed Breakdown

5. SDLT Structuring — Mixed-Use Advantage (Deep-Dive)

Mixed-use properties (shop + flat above, or any building with both commercial and residential elements) are taxed at commercial SDLT rates. This is the single biggest tax advantage in commercial-to-resi.

Key structuring rules:

• Buy the whole property in one transaction — splitting into separate contracts may lose mixed-use treatment.
• Document the non-residential element: floorplans, rateable value, photos. HMRC may query if the commercial portion is very small.
• Jan 2026 Tax Tribunal: Clyde & Co reports a case where combined purchase of resi apartment + parking space + storage unit was successfully argued as mixed-use, saving £1.75M in SDLT. This confirms the principle is alive but HMRC is scrutinising.
• Risk: Government consultation (Nov 2021) proposed apportionment-based SDLT for mixed-use — residential portion charged at resi rates. Not implemented yet but could be resurrected. Act while the current regime lasts.

7. The 9 Prior Approval Matters — How to Succeed

1. Transport: Most high streets already served — low risk. Prepare a simple transport statement.
2. Contamination: Phase 1 desk study (£800–£2,000) for any former retail/industrial building.
3. Flooding: Check Flood Zone 2/3 via gov.uk flood map. If in zone, commission FRA (£500–£1,500).
4. Noise: If above continuing commercial, commission acoustic assessment (£500–£1,200). Mitigate with secondary glazing.
5. Natural light: MOST COMMON REFUSAL. Deep-plan buildings (>8m) struggle. Commission BRE daylight assessment early (£1k–£3k). Restrict unit depth.
6. Fire safety: Only if >18m or creates 2+ dwellings. Budget £2k–£5k for fire engineering.
7. Conservation area: Only ground floor changes in CA. Prepare character assessment.
8. Industrial conflict: Only if adjacent to heavy industry — rare on high streets.
9. Nursery/health centre: Only if last use was nursery or health centre — impact assessment needed.

8. Building Regulations Compliance Costs

9. Kokal Properties — Recommended Entry Strategy

10. Risk Register

1. HIGH Natural light refusal — deep-plan commercial buildings. Always commission BRE assessment early.
2. HIGH VAT (20%) on conversions — can kill marginal deals. Budget upfront.
3. HIGH NDSS geometry won't work — narrow Victorian shops (5m wide) limit to 1-bed per floor. Measure first.
4. MEDIUM Article 4 creep risk — WM councils could introduce Class MA restrictions. Monitor annually.
5. MEDIUM Structural unknowns — pre-war buildings = asbestos risk, poor loadings. Level 3 survey mandatory.
6. MEDIUM Ground floor void risk — if retaining retail, commercial lettings take 6–12 months. Budget holding costs.
7. MEDIUM EPC Band C requirement — residential lets need Band C (proposed). Factor into conversion budget.
8. MEDIUM HMRC scrutiny on mixed-use SDLT — ensure genuine non-residential element is well-documented.

1. Class MA — Deep Dive: Use Class Verification (Critical)

The #1 Class MA refusal from real Searchland cases is verifying the current Use Class under the post-2020 order. Pre-2020 A1 (shops) and A2 (financial services) were absorbed into Class E in September 2020, but NOT all A1/A2 uses automatically qualify — the building must have been in continuous Class E use for ≥2 years at the time of application.

Verification evidence: Business rates records, council tax records, lease agreements, or planning history showing uninterrupted Class E use. Gaps in use reset the clock.

2. The Geometry Trap — Victorian High Street Shop Constraints

Most Victorian high street shops are 5-6m wide × 10-12m deep (50-72 m² per floor). Under NDSS:

• ✅ 1-bed (50 m²) — works per floor
• ⚠️ 2-bed (70 m²) — works ONLY if building is 7m+ wide or L-shaped
• ❌ 2 × 1-bed per floor — needs 100+ m² floorplate (rare in Victorian stock)

Target: Buildings ≥7m wide or with rear extensions/L-shaped floorplates for 2-bed viability. Buildings <6m wide = 1-bed max per floor.

3. SDLT Structuring — Mixed-Use Is the Edge

High street shop+flat = mixed-use for SDLT = commercial rates (0%/2%/5% no surcharge). This is the structural advantage for Class MA deals:

• £200k commercial purchase: £1,000 SDLT vs £7,500 BTL residential (save £6,500)
• £300k shop+flat: £4,000 SDLT vs £14,000 BTL (save £10,000)
• £500k: £12,500 SDLT vs £30,000 BTL (save £17,500)

⚠️ HMRC is scrutinising mixed-use claims more closely (Jan 2026 Tax Tribunal confirmed validity but expect queries). Document the genuine non-residential element thoroughly and ensure the commercial use is real and material (not just a storeroom).

4. VAT Trap — Most Class MA Conversions Are 20%

CRITICAL The 5% reduced VAT rate only applies when the building has been entirely non-residential for ≥2 continuous years AND you're creating new self-contained dwellings. Most high street shops that were trading until recently do NOT qualify — budget 20% VAT on all conversion costs.

On a £180k conversion: 20% VAT = £36k extra cost vs 5% = £9k. That's a £27k swing that can kill a marginal deal.

5. Article 4 Risk — West Midlands Still Clear (May 2026)

No WM council has removed Class MA rights. Confirmed for: Birmingham, Dudley, Wolverhampton, Sandwell, Walsall. This is currently a London-centric issue (Lambeth, Brent, Hillingdon, City of London).

However, as Class MA applications increase in the WM over 2026-27, councils may respond. Check annually via council planning portal. Birmingham conservation areas (Edgbaston, Moseley, Harborne) have Article 4s for minor alterations but NOT for Class MA.

7. Worked Example — Dudley Shop + Flat

8. Strategy Prioritisation — Updated for 2026

9. Top Risks — Ranked (May 2026)

1. HIGH Natural light — #1 refusal reason. Commission BRE daylight assessment for every habitable room. Deep-plan >8m without lightwell = high risk.
2. HIGH VAT at 20% (not 5%) — £27k+ swing vs expectation on £180k conversion. Budget correctly.
3. HIGH Wrong use class verification — pre-2020 A1/A2 doesn't automatically qualify. Verify current Class E for 2+ continuous years.
4. MEDIUM NDSS geometry — narrow Victorian shops (5-6m wide) limit to 1-bed per floor. Measure before committing.
5. MEDIUM Fire safety (Part B) — compartmentation, FD30s doors, alarms. £10k-30k compliance cost.
6. MEDIUM Sound insulation (Part E) — between commercial and residential. £10k-25k compliance cost.
7. MEDIUM Ground floor void risk if retaining retail — commercial lettings take 6-12 months.
8. LOW Article 4 creep — WM safe for now but monitor annually.

10. Due Diligence Checklist

• ☐ Verify current use class = Class E (post-2020) for ≥2 years via business rates/lease
• ☐ Check council planning portal for Article 4 removing Class MA
• ☐ Measure floorplate — must meet NDSS minimums for target unit mix
• ☐ Commission daylight assessment for every habitable room (BRE)
• ☐ Get builder quote — no estimates. Budget 20% VAT.
• ☐ Check Fire Safety Act height triggers (>11m / >18m)
• ☐ Check EPC — min C required post-conversion
• ☐ Check Flood Zone — FRA needed if Zone 2/3
• ☐ Model mixed-use SDLT — factor £6.5k-£17.5k saving
• ☐ Budget 15% contingency on all costs

1. Class MA Framework (2026)

Class MA (Town and Country Planning GPDO 2015 as amended) allows change of use from Use Class E (commercial, business, service) to Class C3 (residential dwellings) without full planning permission. Replaced narrower Class O (offices only) in 2021.

Key Changes (5 March 2024)

• REMOVED Vacancy requirement — occupied buildings can now be converted
• REMOVED 1,500 m² floor area limit — any size now convertible
• RETAINED 2-year continuous Class E use rule
• RETAINED Prior approval still mandatory — 56-day decision window
• EXCLUDED Listed buildings, scheduled monuments, SSSI, safety zones

Prior Approval Matters Assessed

1. Transport & highways
2. Contamination risks
3. Flooding (Flood Zone 2/3 → FRA required)
4. Noise from adjacent commercial uses
5. Natural light to all habitable rooms
6. Fire safety (>18m buildings need fire report)
7. Sustainability of area (loss of commercial floorspace)
8. Housing design & space standards

Cost: £120–£125/dwelling application fee. Deemed consent if no decision within 56 days.

2. Article 4 Direction Risks

• Lambeth (London): 3 non-immediate Article 4 directions withdrawing Class MA in defined areas
• Kingston (London): Proposed for primary shopping areas
• Multiple London boroughs: Various — mainly targeting town centre retail cores
• Chorley: Immediate Article 4 blocking HMOs
• Dudley: Borough-wide HMO Article 4 (effective Sept 2023) — only blocks C3-to-HMO, NOT Class MA C3 conversion. Class MA still available in Dudley for C3 residential. However, any C3 created via MA cannot later convert to HMO without full planning.
• Rule of thumb: Most A4 targets primary retail frontages. Secondary high streets and upper floors are safer.

3. Conversion Costs (2026 Data)

4. SDLT — Mixed-Use Advantage

CAUTION: HMRC increasingly challenging mixed-use claims. Non-residential element must be genuine and material. Jan 2026 Tax Tribunal confirmed mixed-use on combined resi + non-resi land is valid but HMRC is scrutinising.

5. Best Towns for Com→Resi (2026)

6. West Midlands Local Context

WM commercial property investment surged 55% YoY to £2.8B in 2025 (Innes England), outperforming national for first time in 3 years.

7. Financing — Commercial → BTL Remortgage Path

1. Commercial mortgage at 6.0–9.5% fixed (65–80% LTV) for purchase
2. Bridging/development finance at 0.75–1.5%/mo for conversion
3. Remortgage to standard BTL (4.5–5.5% interest-only, 75% LTV on GDV)

8. Top Risks

1. 🔴 Article 4 creep — more councils restricting Class MA
2. 🔴 Building Regulations compliance — sound, fire, thermal cost risks
3. 🔴 NDSS space standards — irregular commercial floorplates
4. 🔴 Natural light — deep-plan buildings with limited windows
5. 🔴 Sustainability of area objection — council can refuse on loss of commercial floorspace
6. 🔴 HMO exit blocked — Dudley's borough-wide A4 locks you into C3
7. 🔴 VAT on conversion works — standard rate 20%
