VAT on Telecoms Masts and Wayleaves

PropertyVAT Team · Updated 21 October 2026 · 3 min read

Mast rents and wayleave payments are minor line items on most commercial sites. They matter out of proportion to their size, because a small stream of exempt income can restrict recovery on much larger costs.

The general treatment

Granting rights over land — a mast site, a wayleave for cables or pipes, an access right — is generally treated as a supply of an interest in land.

So it follows the land:

• No option to tax over that land — generally exempt
• Option to tax covering that land — generally standard-rated

The analysis depends on what right is actually granted. A licence to install and maintain equipment may be analysed differently from a lease of a defined area, so the documentation matters.

Why the amounts are deceptive

A mast rent might be a few thousand pounds a year on a site worth millions. The VAT consequence is not proportionate to that.

If your other income is taxable — opted commercial lettings, parking, storage — and the mast income is exempt, you are making both taxable and exempt supplies. That makes you partly exempt, and recovery on costs relating to both is apportioned.

On a site where you are incurring significant VAT on refurbishment or professional fees, a restriction driven by a small exempt income stream is a genuinely annoying outcome.

There are de minimis provisions under which small amounts of exempt input tax can still be recovered in full, which may cover the position. The thresholds are specific, so it needs checking rather than assuming.

The option to tax trap

Options to tax apply to defined land or buildings, not automatically to everything an owner holds at a location.

So an owner who opted to tax their industrial unit may find the option does not extend to:

• A mast on a separate parcel at the boundary
• Land outside the demise covered by the option
• An area acquired later and never opted

The result is exempt income sitting alongside taxable income, from a site the owner thinks of as entirely opted.

When reviewing an option, check the extent of the land it covers, not just that one exists.

On acquisition

If you are buying a site with mast or wayleave income:

1. Identify every income stream, including the small ones. They are easy to miss in a rent schedule dominated by a main tenant.
2. Establish the treatment of each — taxable or exempt.
3. Check what land the seller's option covers, and whether it reaches the mast site.
4. Work out whether the mix makes you partly exempt, and whether de minimis applies.
5. Consider whether to opt over the land carrying the exempt income, if that resolves the position.

Point three is the one most often skipped, because an option to tax is treated as a yes-or-no fact rather than a question about extent.

Code rights and renewals

Telecoms agreements operate under a statutory regime that affects rents, terms and the ability to remove equipment. Agreements have been renegotiated and valuations contested in recent years.

That is a commercial and legal matter rather than a VAT one, but it bears on VAT in one way: if an agreement is renegotiated or replaced, the supply being made may change, and the VAT analysis should be revisited rather than carried over.

What to do

• Map every income stream on the site, however small
• Confirm the extent of any option to tax, in writing
• Review your partial exemption position if exempt income exists
• Revisit the analysis when agreements are renewed or renegotiated
