Why Connected Party Deals Go Wrong
Connected party SIPP property transactions are among the most technically demanding arrangements in the UK pension landscape. They involve multiple professionals — pension administrators, solicitors, RICS valuers, and sometimes mortgage brokers — each working to strict compliance requirements within defined timeframes. When any element of the process fails, the consequences can be severe: unauthorised payment charges of up to 55%, scheme sanction charges on the provider, and HMRC investigations that can disrupt the entire pension scheme.
The good news is that most mistakes are avoidable. They typically arise from misunderstanding the rules, poor professional coordination, or allowing commercial pressures to override compliance requirements. Understanding the most common failure modes is the first step to avoiding them.
Mistake 1: Getting the Valuation Wrong
The most fundamental requirement of any connected party transaction is that it is conducted at open market value. The most common valuation-related mistakes include:
- Using a non-independent valuer: Commissioning a valuation from someone who has previously acted for the member or their business. HMRC can challenge the independence of the valuation and therefore the validity of the price.
- Using an outdated valuation: Markets move. A valuation obtained six or twelve months before the transaction may no longer reflect current market conditions. Most SIPP providers require a valuation dated within three to six months of the transaction.
- Agreeing the price before getting the valuation: The connected parties agree a price between themselves and then commission a valuation they hope will support it. This is the wrong order — the valuation must drive the price, not validate it.
- Failing to renew the rent valuation at reviews: Setting up the lease correctly but then allowing rent reviews to pass without obtaining fresh RICS evidence of market rent.
Mistake 2: Rent Payment Failures
Late or missing rent payments by a connected party tenant are the single most common compliance failure in connected party SIPP arrangements in practice. HMRC treats significant or persistent late payment as evidence that the rent is not being collected on commercial terms — which can be characterised as the SIPP providing an unauthorised benefit to the connected party.
Common rent payment mistakes include: setting up manual payments rather than standing orders; allowing a temporary business cash flow crisis to result in deferred rent without the SIPP provider's involvement; informally "agreeing" with the provider that late payment is acceptable; and failing to charge interest on overdue rent as required by the lease.
The correct approach when a connected party tenant faces genuine cash flow difficulties is to notify the SIPP provider immediately and take legal advice. The SIPP must treat the tenant as it would any commercial tenant — which means pursuing the debt. This can feel uncomfortable when the tenant is your own business, but the consequences of not doing so are far worse.
Mistake 3: Occupation Without a Lease
A connected party occupying SIPP property before the lease has been formally executed — even temporarily — constitutes an unauthorised use of SIPP assets. We have seen situations where a business has moved into premises while the lease is still being finalised, believing that "it will be sorted in a few weeks." HMRC takes a strict view: the moment a connected party occupies the property, the lease must be in force.
Similarly, allowing a connected party to use part of the SIPP property — a meeting room, a storage area, a car park — that is not covered by the lease is an unauthorised benefit. Every part of the property used by a connected party must be covered by a formal, approved lease at market rent.
Mistake 4: Acquiring Prohibited Property
The most catastrophic mistake in any SIPP property context — connected party or otherwise — is the acquisition of residential property. Residential property is a prohibited investment for SIPPs, and the tax consequences of holding it are severe. The property is treated as an unauthorised payment equal to its market value, subject to tax charges of up to 55%. This is not a recoverable situation — the tax charge cannot be reversed even if the property is subsequently sold.
The residential property prohibition extends to mixed-use properties where the residential element is not genuinely incidental. It also catches properties that are permitted as commercial but converted to residential use while in the SIPP. Any change in the property's use should be reviewed against the residential property prohibition before it proceeds. Our article on mixed-use property and SIPPs covers this area in more detail.
Mistake 5: Poor Communication With the SIPP Provider
Many connected party transactions run into difficulty because the member or their advisers fail to engage the SIPP provider early enough or keep them sufficiently informed as the transaction develops. SIPP providers are acting as trustees and have veto rights over transactions they consider non-compliant. Presenting a provider with a completed transaction that was never approved is a compliance failure — not a clever fait accompli.
The correct approach is to engage the provider at the outset, share the proposed transaction structure, obtain their preliminary approval in principle, and then keep them updated at each stage. Most providers have a defined connected party transaction checklist — following it to the letter is the most reliable way to avoid surprises at the point of completion.
